"Peng!"

A dull collision sounded on the school ground of the artillery army camp. This was the sound of the stone generator's wooden poles colliding with a thick cotton bracket wrapped in a thick cotton cloth. The torque of the two tendons turned into a huge thrust at this moment, ejecting a stone above six kilograms, drawing a graceful semicircular arc in the air, crossing the apex, and then sliding down rapidly, and finally hitting heavily on the ground sixty or seventy steps away.

"Okay!" A loud voice of cheering came as the black-faced Lu Shihu stroked his black and shiny beard that was maintained and shouted loudly.

"Qingzhi, the time limit given by my husband has only been two days, and the first stone-driving machine has been completed. It seems that in 60 days, you can present 300 stone-driving machines to my husband. At that time, I will definitely get some credit, and maybe Brother Yu can also benefit from this opportunity."

Chen Dexing dared to issue a military order, so he was naturally confident. Jia Sidao gave him two months and three days, which was almost 63 and 4 days. Just two days later, the first "prototype machine" has been successfully trial-made. Next, as long as the size is enlarged, he can create a stone-driven machine that meets Jia Sidao's requirements. With hundreds of craftsmen who can do carpentry work and at least more than 600 soldiers who can start, he can build 300 stone-driven machines in the artillery army in 60 days, which can be completed with his eyes closed. The time given by Jia Sidao is actually very relaxed.

"Peng!"

There was another muffled sound, and the "prototype machine" was still shooting stone bullets. Lu Shihu looked at the pile of stones next to the small stone generator, and was a little puzzled.

"Qingzhi, do these stones be knocked out with a stone generator?"

"Yes, you have to pick it up after the shooting, and continue until the stone generator is damaged." Chen Dexing said lightly, "In this way, you can know the durability of this stone generator."

"Durability...?" Lu Shihu repeatedly said this new term several times and understood the general meaning. "Qingzhi, do you want to know how many times a stone generator can re-launch stones?"

Chen Dexing nodded, "Senior Brother Lu should know that the bow and chord force will become weaker and weaker. The twisting and lever of the stone generator and the crossbar used to block the lever should all be used for the number of times."

The stone generator designed by Chen Dexing is quite sturdy. The main frames are assembled with hardwood and reinforced with iron parts in key parts, which has a certain degree of durability. However, the catapult device of the stone generator is always a consumable component and must be easily replaced - that is to say, the various components of this stone generator must be of uniform specifications and can be interchangeable!

This is difficult and easy. The difficulty lies in the fact that the craftsmen's craftsmanship is taught by different masters, each with its own standards, and even the rulers used are of size. The easy reason is that the craftsmen under Chen Dexing's command now occupy the military quota and are soldiers of the Song army. The army has its own laws, and Chen Dexing can use military orders to implement his standards. Just today, he ordered the craftsmen in the army to create a batch of measuring tools according to the samples he gave, including rulers, triangle rulers, compass, protractors, parallel rulers, right angle meters, and anemometers. Some of these measuring tools are for craftsmen of the artillery army.

In addition to unifying the gauge standards, Chen Dexing also plans to divide his more than 100 craftsmen into dozens of teams, most of which only create one part of the stone generator. In addition, there is a team responsible for inspecting the quality and size of the parts, several teams responsible for assembling, and a team responsible for inspecting the quality of the finished product. Moreover, in the eye-catching position of each component and the entire stone generator, there will be the name of the craftsmen responsible for building and acceptance, so that if quality problems arise, they will be held accountable!

Under such strict quality control, Chen Dexing naturally had the confidence to build high-quality stone-generating machines. However, these stone-generating machines were just the beginning of a whole "national-salvation plan". The second step of this plan was to introduce the three-layer pulp warship into the Song Dynasty naval army.

Because in Chen Dexing's view, such warships combined with stone generators and arson bombs are the powerful tools that can truly dominate the waters of East Asia.

"Qingzhi, you said you still want to build a ship?"

Hearing Lu Shihu's question, Chen Dexing smiled and nodded, "I just want to verify the power of the three-layer pulp warship. If it is really available, it should be offered to you by the Lord of Privy Council. Brother Lu, can you please help Yu join forces to promote this matter?"

Lu Shihu frowned while holding his beard, "Qingzhi, the cost of these three-layer pulp warships is not expensive, right?"

"It's not expensive. If you use copper coins, ten thousand guan is always needed. However, it won't cost so much to build a small boat for verification. It's enough to have a thousand guan."

"How to... verify?" Lu Shihu's expression suddenly became full of curiosity. He glanced at the stone launcher that was firing stone bombs, "Do you want to build a small one too?"

"Build two ships, one is a single-layer pulp ship used to verify the impact angle, and the other is a double-layer pulp ship used to verify the possibility of multi-layer pulp seats." Chen Dexing smiled and promoted his plan to Lu Shihu-he had seen the battleship drawings for Liao Yingzhong before, but the other party did not understand water war at all and had little interest.

Therefore, Chen Dexing believed that the only way to get Jia Sidao to support himself in building a three-layer pulp warship is to prove it. He had to show him the power of this Western-style warship in front of Jia Sidao. However, Jia Sidao is a busy man, and it is not easy for him to take advantage of his busy schedule to go to the canal east of the city to watch the collision. Fortunately, Jia Sidao sent Lu Wende's nephew to his army as an opportunity.

Lu Shihu's uncle Lu Wende was in charge of the army to aid Sichuan. He was blocked by the Mongolian commander Nuelin and was blocked east of Lin City, Fuzhou by floating bridges and warships, and it was difficult to advance in a short distance. Once Diaoyu City fell, the two armies of Wang Jian and Liu Chi in Sichuan would be decisively destroyed. The five prefectures of Ding, Li, Chen, Yuan and Jing, controlled by the generals of the Lu family, were the front line of the fight against the Mongolian army. At that time, the children of the Lu family in Anfeng would die in a pile.

Therefore, Lu Shihu was very interested in any new weapon that could help Lu Wende break the Mongolian army blockade. Just when he wanted to ask further details, he heard a disturbing sound, and someone was vaguely crying and scolding. Then he saw someone pushing the door and walking into the hall. It was the monk Liu, who was the commander of the right army of the artillery army.

"Monk, something happened outside." Chen Dexing looked at Monk Liu, and saw that his face was full of indignation, not knowing what happened.

"Brother," Liu Monk Shang made a move and called Chen Dexing according to the order of Qionghua Tower's charity. "The Tartars drove people into the city. They were all people of our Song Dynasty! They were all bullied so much..."

"Are they the people outside Yangzhou City?" Chen Dexing asked with a frown.

"Not only, there are so many people, I don't know how many!" said Liu Monk, "It should be driven by the dog Tartars from other places."

"This is the Beilu who wants to consume the food and grass of Yangzhou City. Perhaps there are some tricks mixed in. These are the common tricks of Beilu!" Lu Shihu touched his beard and said with a pale face, "Is it possible that the Shumi Gong let the people enter the city?"

"It should be released. The city gate of Beiguan is wide open. The ten-mile-long street is full of refugees coming from outside the city. It is like a tide. I don't know how many!"

"What happened?" Lu Shihu was stunned. Jia Sidao's move to let the people enter the city was obviously beyond his expectations. He looked back at Chen Dexing, "Qingzhi, I'm afraid that there will be some tricks and take the opportunity to make trouble! Don't be wary of it."

Chen Dexing nodded and said to Monk Liu: "Transfer the general order, the whole army is on guard!" Then he said to Lu Shihu, "Brother Shi, let's go and have a look together."
