The 100,000 people in the military city have been adapting for a year. Li De did not intend to send troops rashly. He must understand the situation in Liaobei and prevent the sneak attacks of the Goryeo people.

Another thing is that he is very busy now. The application of Zhuge crossbow chariot has given him hope. When fighting, the ships and cannons must be strong. The location of the military city is very special. It is a place of a heavy defense, so it must be foolproof.

So Li De was not idle, and Yanyun Cavalry and the elite soldiers of the military city were cooperating with the chariot tactics to perform drills to play the greatest role of the chariot.

The chariots and cavalry were conducting exercises repeatedly, and Li De watched from the side, and there was a tactical plan given by Li Jing and others on the table in front of him.

"Li Jing, Zhuge crossbow truck has been used. What do you think is there any shortcomings?" Li De asked.

"The chariots exert the power of crossbow arrows in close combat and can effectively break armor. If it is to say that the disadvantage is that the arrow is too small, the lethality caused by insufficient." Li Jing said.

Li De actually didn't say that in ancient times, some strange things would be applied to hidden weapons, and it was not difficult to cause lethality.

But it's hard to say this kind of thing openly.

"Letering power, you remind me that the bearings on the crossbow carts now need to be longer. If you lose the ability of the crossbow cart, you can still use it as a crash. You should hit a few long hammers on the cart."

Li De proposed a new plan, but Lu Mingyue around him didn't think so.

Lu Mingyue followed Li De to Bingcheng to test the actual application effect of the new type of combat vehicle. After yesterday's battle, many people have some understanding of the performance of the combat vehicle.

As a craftsman and a builder of the chariot, Lu Mingyue naturally has a better understanding of the chariot.

"Grandmaster, the load-bearing of the crossbow truck has reached its limit. If the impact of the wooden cone is installed, the speed of the tank will decrease and affect the maneuverability."

Li De nodded. It is better to let professionals handle professional work. He just wants to use the multifunctionality of the chariot, but not all chariots can have multifunctional abilities.

He thought that in terms of current technology, it was already considered a very cross-age thing to be able to invent the Zhuge crossbow. Li Jing said that the lethality was not enough, but in fact he decided that it was indeed the case. He thought that it would be great if the equipment in later generations had the ability to kill a range like those of later generations.

After seeing the Spitfire Chariot appear, it is really like seeing a big killer.

"Range damage, how about Piercing the Sky Monkey?"

Li De suddenly thought of a fireworks that he played with when he was a child. The firearms developed very advanced after the Ming Dynasty, but they did not give full play to their leading advantages.

"Yes, the monkey in the sky is a killer weapon for range damage."

When Lu Mingyue saw the Grand Commander whispering, she couldn't understand it but it didn't affect him. She had already guessed that the Grand Commander had come up with new things.

In fact, the biggest trump card of the Pioneer Soldier is black gunpowder. It has been used in several key battles as the top secret of the Pioneer Soldier. Now I will mention it again to further apply gunpowder.

Li De’s idea is very simple. It is actually good to use it to make some smoke to confuse the public. It is really like the Chuantian Monkey. It is OK to play with it. There are still dangers in the application. After all, many things in technology cannot meet the requirements.

However, this does not affect the use of gunpowder as auxiliary equipment.

The rocket that he just came up with has been denied by him. One is the question of distance, and the other is that the damage range and power cannot achieve the desired effect.

It is better to settle for the second best and make some smoke bombs to use, which can be used in conjunction with a weapon with indiscriminate attacks like Spitfire Tank.

The enemy cannot see the location of the Spitfire chariot clearly, and the use of smoke bombs is not only single, it can also specify positions.

Cooperating with tactics will have a good effect.

When Lu Mingyue saw Li De, she smiled foolishly, and didn't dare to ask, so she could only stand aside and wait for him to come back to her senses.

After a chariot training, He Bida came to Li De. He sweated a lot and asked before he could wipe it, "Grandmaster, do we still need to correct our tactics?"

Li De was interrupted by He Bida's voice. In fact, he was just imagining that he thought about it for so long and had the chariot run a lap.

"It's pretty good, let's have a rest." Li Dedao.

He Bida then took his people to rest. The soldiers could not leave the main generals. They had to gather together to discuss tactics. This was the habit of the middle and senior generals of the vanguard soldiers.

It all corresponds to what Li De said. If there is only one problem, then there will be countless answers to the problem. All the lieutenants and lieutenants have implemented the meaning of this sentence, and there are enough plans no matter when.

Li De, who was sitting aside, encouraged them to do so. He was not involved and was afraid that the generals would be nervous. He still had many ideas. Now that he had chariots to assist in combat, should he start a plan for air combat?

Suddenly, an inspiration made his thoughts start to be wild. Since there is the Zhuge Divine Crossbow, can the wooden ox and flowing horse be realized?

Legend has it that the wooden ox and horse are very powerful. He has also seen someone restore this magical cargo transport tool, which is actually a wheelbarrow with a bracket, and some people say it is a four-wheeler.

Li De thought about the vehicle carefully and had already made a large number of customizations in Youzhou Workshop, and suddenly he thought of something very powerful.

Kongming lanterns, when he was on the wall of the military city, had this idea. Although Kongming lanterns could be launched at night, they were also flammable things. If they were released on the wall, they would fall after being ignited after being evacuated.

If the Kongming lamp is filled with tincture oil, it will cause damage to enemies on the ground. This method is suitable for when the weather symbols are in their favor.

You can use defensive cities.

Li De recorded all the whimsical things, and whether they were useful or not, they had to be made and tested before they could be known.

Lu Mingxing knew that these craftsmen were here to live again.

Just as Li De was studying various new items in the Bingcheng, Yanmen and Shuofang on the border of the Sui Kingdom were attacked by Turkic soldiers, especially the Yanmen Pass had been lost, and 100,000 Turks were going directly through Yanmen and were about to attack Taiyuan.

Emperor Yang of Sui in Jiangling was furious. How could he not be angry when he was defeated and was invaded into the pass by the Turks?

"I remember that he recruited 50,000 elite soldiers. Now only the Duke of Tang sent troops to resolve the current crisis." Emperor Yang of Sui said to several confidant ministers.

The ministers looked ordinary, not because they were not worried, but because they were in Jiangling, even if the Turks entered the pass, they probably wouldn't be able to hit Jiangling, so they were not in a hurry.

He just obeyed the orders of Emperor Yang of Sui.

The Duke of Tang in Taiyuan Prefecture has received news that 100,000 Turkic cavalry entered the country from Yanmen Pass and drove straight into Jiangling.
