??The acceptance meeting of the Sky Thunder was "successfully closed" in Xianduyuan, the western suburbs of Yecheng. The guests praised the power of the Sky Thunder, and Prime Minister Yuchi Jiong was very satisfied with the weapon presented by Shannan.

There were many exchanges of interest between Shannan and the court. The more than 10,000 war horses allocated by the court in Shannan were just a "deposit". Now that the Hongtian Lei was successfully accepted, the remaining "final payment" could be settled.

After talking to Yuwen Wen for a moment, he said many encouraging words such as "Young man, do it well, I'm optimistic about you." Yuchi Jiong took the lead in returning home, and the rest of the people left one after another. Yuwen Wen did not rush to leave and stayed there to chat with his father-in-law.

That day, he "spun the palace" and returned to the palace to recover from his wounds. Yuchi Shun came to visit him, and he also met when he handed over the secret recipe of Hongtian Thunder. After all, the two were father-in-law and son-in-law, so there were more topics to talk to.

The thunder of the sky was a smooth handover, and many affairs of Shannan and the court were sorted out. There was no special big thing next. After the Shannan delegation returned, Yuwen Wen would stay in Yecheng for three months.

During this time in Yecheng, only Yuchishun's family was considered a relative of Yuwen Wen. Just like before, Yuchishun was in Anlu, there was only a place between his father-in-law and son-in-law.

Seeing that his son-in-law's eyes narrowed slightly, as if he was starting to hold back his water, Yuchi Shun couldn't help but knock: "It's up here, I'll visit Duke Shu in a few days. I'll accompany you together, so don't make any troubles."

He mentioned that his father used the title of "Duke of Shu" instead of "Prime Minister", in order to lighten the officialdom and appear closer. After all, his son-in-law is also his father's grandson-in-law, so it is much more relaxed to visit as a junior.

"Are Wei Angong and others here too?" Yuwen Wen asked,

"It's not clear that it's just an ordinary family banquet after all. I believe that Duke An of Wei and Duke Xidu will not come."

After hearing what his father-in-law said, Yuwen Wen nodded and visited the Prime Minister's Mansion as he was. He was not yet at the point where Yuchi Dun and Yuchi Youqi had to sit with him, but he didn't want too many people.

Yuwen Wen was not afraid of facing the men of the Yuchi family, but these people were all the ones who led troops to fight. Their drinking capacity should be similar to his father-in-law. If he had to go out for a few rounds of wine, he would have to go out sideways.

If you get into trouble after drinking, it will be a bad thing!

After drinking too much, he got drunk and got crazy on the spot. It shouldn't be the case if he saw a woman. Yuwen Wen was just worried that after sobering up, he would be a bit bloody when he was surrounded by many people, a beautiful and disheveled sleeping woman, who would make her hit the ball later.

He doesn't like the feeling of losing control and being merciless, just like taking Diyega before, how nauseous it is. Fortunately, he is not addicted. Whether intentionally or unintentionally, Yuwen Wen has sent someone to check it quietly.

After talking to his father-in-law for a while, he followed the opportunity and proposed to visit Xianduyuan, which was temporarily designated as the experimental land for the Sky Thunder, so Yuchi Shun, who was specifically responsible for the Sky Thunder production, could make the decision.

"I'll try it out later, don't be scared." Yuchi Shun explained. Seeing that his son-in-law nodded, he sent an official to take the other party around, and accompanied him to make sure that he could make a move.

Xianduyuan has been abandoned for several years. Although it has been repaired again and there are soldiers guarding it everywhere, Xianduyuan covers a wide area. In addition to the places where the sky thunder are made, the defense is tight, and there are inevitably robbers from other areas, including chickens and dogs.

The son-in-law has a slightly special identity, so nothing can happen. Otherwise, Yuchi Shun would not be as instructed as his father, and it would be even harder to explain to his daughter Yuchi Chifan.

......

Yuwen Wen stood on the "Zhongyue Songshan" and looked at the surrounding mountains in the east, south, west, and north. This former royal garden was indeed grand enough. It piled up soil to make mountains, digging ponds and seas. Flowers, plants and trees were planted everywhere. Looking up, it looked lush and lush.

But now it has been ruined for many years. Looking at the remains of buildings drowned in the sea of ​​trees, a ridiculous feeling suddenly appeared in his heart, as if he was in the American jungle, with a Mayan city ruins in front of him.

The prosperous towers of the past are now empty, and the birds landed on them are chirping, as if telling the lively scene of the past.

"I saw him rise up a tall building, he saw him entertain guests, and he saw his building collapse..." Yuwen Wen murmured, turned around and walked down the mountain, while acting as a tour guide. Listening to him humming, he felt the words were filled with sadness.

Yuwen Wen walked on the forest path, looking at the flowers and plants on both sides, thinking about things. The Yuchi family's camp was quite shocked just now. When he was envious, he was also planning to circle around.

Just when talking to his father-in-law, Yuwen Wen wanted to say that his father-in-law would have to be introduced to him in the future, so he went to Yuchi Dun and Yuchi Youqi's mansion to visit him, but then he thought about it and gave up. He just wanted to go by himself, and let his father-in-law go it was unhappy.

My father-in-law and his two younger brothers are half-brothers, and they are just a little bit of a relationship with each other. Like the stepmother in the usual sense, the stepmother Wang is not very good to Yuchi Shun, who is not born. She just wants to dial all the dishes in the dish to her two sons.

Yuwen Wen once heard his wife Yuchi Chifan mention it. Since Yuchi Jiong's re-stringing, there has been a fire in the backyard in the mansion.

Yuchi Jiong's original wife was Princess Jin Ming, daughter of the Western Wei emperor Yuan Baoju. She gave birth to Yuchi Yi, Yuchi Kuan and Yuchi Shun. After Yuan died of illness, she returned to Xian Wang and gave birth to Yuchi Dun and Yuchi Youqi.

Yuchi Wulang Yuchi Youqi was considered to have a son from Yuchi Jiong when he was old. Although Yuwen Wen was not sure about the specific age of this "Fifth Uncle", the other party was similar to his brother and his name was "Youqi". You can think of Yuchi Jiong who loved this son quite much.

In ancient times, it was called "Qi". According to the ages of Yuchi Youqi and Yuchi Jiong, Yuchi Jiong was about the age of about 60 years old. The meaning of "Yuqi" was to bless him, the old man, and the name of "Yuqi" was very clear about the love for his youngest son.

At this time, Yuchi Jiong was over 60 years old, and his energy was naturally not as good as before. The relatively young Xuxian Wang was very energetic and capable of taking charge of the affairs of the mansion and extremely protective of his two sons based on human nature.

Therefore, the relationship between the first three sons of Yuchi Jiong and the last two sons was not very good. The three sons left by Yuanshi are now gone, and the remaining Yuchi Shun is naturally alone.

Yuchi Shun had no son and basically had no chance to take over Yuchi Jiong's mantle, and could not threaten Wang's sons Yuchi Dun or Yuchi Youqi. I think in the eyes of Wang, the threat has been reduced a lot.

However, it will definitely be of great use to recall his son from thousands of miles away. I don’t know if Wang would blow the pillow wind and fan the cold wind to light ghost fires to prevent Yuchi Shun from endangering his son’s status and share more property in the future.

It is precisely because of this that Yuwen Wen wanted to help his father-in-law and secret recipe for thunder. He only handed it to Yuchi Shun, and said in front of Prime Minister Yuchi Jiong, "If there is any leakage, please kill the Duke of Angu County to warn others."

Although I had the idea of ​​getting a little trick, it was mainly to help my father-in-law. No matter what the secret, the fewer people know, the easier it is to keep it secret. Anyway, Yuchi Shun knows it, and it is not difficult for Yuchi Jiong to know it.

Yuchi Shun is responsible for the production of the Sky Thunder. As long as Yuchi Jiong is not too partial, this is the only business. Yuchi Shun has a greater say among his peers with this weapon.

The reason why I thought of this was that Yuwen Wen had fantasies that could incite internal struggles in the Yuchi family and achieve the benefits of the fisherman's profit. However, if you think about it carefully, unless Yuchi Shun has a son, who else can such a hard struggle be passed on to?

Yuchi Jiong's five sons, Yuchi Yi, were killed. The sons were underage and imprisoned in Chang'an by Yang Jian, and they did not know how life and death were. Yuchi Kuan died early and could not leave behind his descendants.

Yuchi Dun left Chang'an three years ago, and his family was trapped there. Later, after the prisoners exchanged, his wife and children came to Yecheng. His younger brother Yuchi Youqi was married and had a son. Just by whether he had children or not, Yuchi Shun would definitely not be able to fight.

Unless there is a son, this is not impossible to solve. Yuchi Shun can adopt one of his brother Yuchi Yi's sons, but the key is that those who can come back alive must be normal people and have not been castrated. This is not a joke.

When Yuwen Tai founded the Western Wei Dynasty, his nephew Yuwen Shifei was trapped in the hands of the powerful minister Gao Huan and was killed soon after. Yuwen Shifei's son Yuwen Zhou was young. Although he survived, he was castrated and sent to the palace to be an eunuch.

Later, when East and West exchanged prisoners, Yu Wenzhou returned to his uncle Yuwen Tai, but he was disabled and unable to reproduce his offspring. It was uncle Yuwen Hu who adopted his youngest son to him and continued the incense.

Yuwen Hu was regent and killed two cousins ​​who were emperors. He was killed by his third cousin Yuwen Yong, who was the emperor. All his sons were killed. Yuwen Hui, who was succeeded to Yuwen Zhou, was not spared. Yuwen Zhou became a lonely man again, and finally died in the war in the second year of Daxiang, leaving his descendants.

In view of this, Yuwen Wen felt that it is very likely that Yang Jian would play in the performance art eunuch, so don’t have too much hope. If Yuchi Shun doesn’t have a son, it would be boring to fight around, even though his son-in-law is still worth half of his son...

Anyway, it is impossible for Yuwen Wen to become Yuchi Wen!

"Duke of Xiyang County, the time is coming." The official next to him suddenly reminded. When Yuwen Wen heard this, he remembered that his father-in-law mentioned that he would try to explode the sky thunder, but this place is quite far from the venue, so the sound would not be deafening.

Yuwen Wen has now come to a large pond by the forest, looking at the calm water surface, standing quietly waiting for the loud noise, and many birds fell from the trees in the forest, chirping from time to time.

The surroundings gradually became quiet. At this moment, a dull thunder sound suddenly came from the east, alarming countless birds in the forest. Seeing the frightened groups of birds hovering in the sky, Yuwen Wen's thoughts also flew into the sky.

Two years after the thunder of the sky was launched, there was still no choice but to spread technology, which will sooner or later spread to various countries.

The sky-booming thunder is a fried pot or bag made of fire and medicine. The gunpowder is very simple, but it was discovered by alchemists in history until the late Tang Dynasty. Its characteristics were discovered by people and then put into military use. However, the form of the sky-booming thunder did not appear until the Song Dynasty.

Yuwen Wen advanced the appearance of the sky-blasting thunder four or five hundred years ago. From the moment he entered the battle, the spread of technology was inevitable. After all, everyone wanted such a sharp weapon, and once the court had thought about it, Shannan could not hold it.

Unless they proclaim themselves as kings and do not surrender to others, but are too weak, that is impossible.

Not only that, the gravity trencher has also spread out. This simple siege equipment has actually nothing surprising. Compared with the human trencher, the principle is simply a layer of window paper.

Based on the speculation that the Sui Kingdom might have mastered the gravitational catapult technology, Shannan actively presented the drawings of the gravitational catapult to the court. The Sui Kingdom, which was suffering from the gravitational catapult, really mastered this technology, and the offense and defense of both sides returned to the starting point again.

The continuous reinforcement of city defenses in various cities on both sides weakened the power of gravity catapults. The battle example that took only a few days to break through Xiangyang may be difficult to reproduce, and Chen Guo in Jiangnan won this technology not long before it was obtained.

'Fortunately, the cannon was not launched, otherwise it would be really over.' Yuwen Wen thought in his heart that the shadow of technology spread was the reason why he dared not let the cannon "come out".

Wars are continuous, and once military technology breaks through, unless the holder can quickly defeat the enemy country, various forces will naturally rise up and follow suit. War is the best catalyst for technological progress. Yuwen Wen knows the structure of artillery, but he dare not create it and put it into combat.

Artillery and muskets are a major innovation in the form of fire medicine utilization. Artillery is a powerful tool for field battles, siege and defending cities. The size of national strength directly affects the number of artillery.

Cast cannons require a lot of metal, and shells are no exception. Fire medicine requires a lot of saltpeter and sulfur. These are all short of Shannan. Once various forces have an arms race for casting cannons, Shannan will definitely be at the bottom.

Yuwen Wen has a secret method to solve the problem of nitrification, but sulfur is difficult. There is not much natural sulfur in the territory of Shannan Prefectures and counties. Using pyroferite to prepare sulfur is also "high-tech". The output of fire medicine cannot be increased, let alone the large amount of copper required for casting cannons.

The metal of cast guns can be bronze or iron, but the difficulty of casting iron cannons is greater than that of bronze cannons. Whether it is iron or copper, there are no large mines in Shannan today. If the raw materials are insufficient, don’t want to compete with others to build cannons.

The power of the cannon is obviously far beyond the thunder, and the principle is not much complicated. Yuwen Wen’s concern is that once the cannon is released, all forces will sooner or later master this high-tech weapon.

It would be fine in the Central Plains. If the Turks on the grassland master artillery, it would be a disaster.

Just like the Later Jin Dynasty in the late Ming Dynasty, when there was no artillery force, it would only cause trouble in Liaodong. With artillery, it would be unstoppable. The Ming army could not defeat the Later Jin army in field battles, so they could only rely on the strong city to defend and wait for assistance. However, with the other party having siege artillery, everything was over.

Nowadays, there are constant disputes in the Central Plains, and the Turkic army on the grassland, with the strong power of Maduomo, can unscrupulously invade the Central Plains to "kill the grass valley". The Central Plains army can only defend the city, Jianbi Qingye and other main forces to rescue it. Once the Turks obtain artillery, the city will not be able to defend.

The Turks were originally the iron-forging slaves of the former overlord Rouran, the former overlord of the grassland. The metallurgy level was not bad. They backed Rour and then became the new overlord on the grassland. An empire with many cavalry, and they mastered the weapon of artillery. The scene was so beautiful that Yuwen Wen dared not think about it.

It took three or four hundred years to appear in the late Tang Dynasty to the prototype of artillery in the Yuan Dynasty. If there is no interference and according to the normal evolutionary route, Yuwen Wen may never see artillery in his life.
