Ailang couldn't help but shout, "It's not just that it's much stronger! It's so much stronger!! How can the tinder tank be compared with this thunder and fire bomb!! It's just one in the sky and the other on the ground! Yueying, you're so amazing!!!" Huang Yueying was so happy when she heard Ailang's praise! The tinder tank mentioned in the conversation between the two of them was actually a very common weapon in this era, and it was the most primitive incendiary bomb. It was to use the can to fill the tinder oil mainly made of tung oil for combustion.

The agent was then ignited and shot out with a catapult. The can hit the ground and immediately shattered, and the turtle oil in it immediately overflowed and burned violently when it encountered fire. It was a very powerful weapon in ancient times. However, the power of the turtle oil tank cannot be compared with the thunder and fire bombs in front of you. If you want to use the turtle oil tank to create the current burning effect, at least twenty or thirty catapults would have to fire the turtle oil tanks at the same time. In other words, the power of the thunder and fire bombs is at least five or six times that of the turtle oil tank, or even stronger.

Ailang suddenly thought of something and asked improvisably: "Yueying, this kind of gunpowder is much more powerful than before, right?" Huang Yueying nodded, "I used the purification method, and the power of gunpowder has been greatly enhanced..." Ailang hurriedly asked: "Can it be used on cannons?" After Ailang came to this era, he was determined to use gunpowder weapons far beyond this era to abuse the army of this era, so he was obsessed with the cannons.

Huang Yueying shook her head and said, "No!..."

"no?"

Huang Yueying explained: "I have tried it. The power of gunpowder burning can indeed remove the projectiles, but its power is very limited, and it is not as good as ordinary stone casters! However, the production of cannons is very expensive and very consuming iron materials! I think this kind of cannon is really, really..." Huang Yueying didn't continue. However, Ailang understood what she meant, and she meant that 'cannons are really useless and expensive waste'.

Ailang was very unwilling to give up and said angrily: "I don't believe it! Why can't it be possible?" Huang Yueying said: "Maybe, maybe it's because the purity of gunpowder is not enough, which leads to insufficient power. I will continue to find ways to purify gunpowder. Maybe one day the cannon can really exert the power described by my husband!" Ailang nodded, feeling that this is the only way to do now.

At this moment, Ailang saw more than 200 technicians below shouting horns and pushing a huge object covered with tarpaulin. Ailang was surprised and hurriedly pointed to the thing and asked, "What is that?" Huang Yueying smiled and said, "Honey, did you mention to me before, there is a heavy catapult that can take more than 350 steps (more than 500 meters)?" Ailang immediately opened his eyes wide and looked incredible. He naturally remembered what he said to Huang Yueying. At that time, he was just drinking with Huang Yueying and was so excited. In order to show off his knowledge, he once appeared in the "Exploration and Discovery" Festival.

I just said it with added fuel to the fire. Ailang told Huang Yueying at that time that the method of using extended arm rods and increasing counterweight should be able to create a heavy catapult with a range far exceeding all current catapults. However, when Ailang watched that episode, he only watched half of it. In fact, he still didn't understand many things, so he never wanted to ask a technician to make it. However, what Ailang never expected was that the speaker was unintentional and the listener was intentional. Huang Yueying actually tinkered with this heavy catapult that had not appeared until the Song Dynasty based on his ideas?!

Ailang looked at the object as huge as a hill and widened his eyes and felt incredible.

Not long after, the more than 200 technicians finally pushed the catapult cart like a hill into position. With the middle-aged technician shouting, more than 20 young technicians took action together and pulled down the huge tarpaulin that was covered by the catapult cart. As soon as the tarpaulin left, the true face of Mount Lu immediately showed off. Ailang saw a huge catapult cart as tall as a hill, just like the packed catapult cart in the game "Age of Empires 2" appeared in front of him. Ailang was shocked and could not speak.

Huang Yueying saw Ailang's expression in her eyes, and her eyes couldn't help but show a proud look.

As the middle-aged technician shouted, more than twenty technicians pulled a rope backwards, and the arms that were originally raised were slowly flattened. Then more than twenty technicians adjusted the counterweight. The twenty technicians had released the rope before, and the arms were kept level and did not lift up. Five or six particularly strong technicians came over with a huge rock of hundreds of pounds. With a shout, he suddenly lifted the stone and placed the stone in the huge iron spoon on the top of the arm. The middle-aged technician shouted again, and more than two hundred technicians immediately grabbed a rope connecting the counterweight and the end of the arm. The middle-aged technician signaled everyone to prepare, and everyone held their breath and waited for the middle-aged technician to give the order. Ailang couldn't help but feel nervous when he saw this scene.

The middle-aged technician shouted loudly: "Start!!" Then the more than two hundred young technicians shouted and pulled the rope together to run back. The rope quickly dragged the counterweight and the tail of the throwing arm. The originally flat arm raised upwards at an extremely fast speed! With a loud bang, the large rocks of hundreds of kilograms actually flew into the sky, flew high, and flew away. After a while, the huge rock fell into the middle of the river in the distance. After a while, the loud noise of heavy objects falling into the water came from!

The first time Ailang saw such a fierce catapult, his chin fell to the ground! He had always been very suspicious of the range of the heavy catapult mentioned in the "Exploration and Discovery" program. In his opinion, how could the primitive catapult throw a huge rock worth hundreds of kilograms away five hundred meters away? However, seeing this scene today, Ailang finally believed that the Chinese ancestors were really incredible!

"Husband, how about it? This catapult car is good, right?" Huang Yueying asked proudly.

Ai Lang came back to his senses, gave Huang Yueying a thumbs up, and exclaimed: "Wife, you are so awesome!" Huang Yueying couldn't help but smile, with a smug charm between her eyebrows. Being able to show off in front of her husband and make her husband stunned was Huang Yueying's happiest thing.

Ailang suddenly thought of something and asked: "Yueying, can this catapult car be manufactured at the siege site so complex?" In this era, heavy equipment was not transported from the rear like modern society, but was temporarily made at the siege site. The army generally only carries some key metal components. Generally, after the war, the army will dismantle the metal components and leave the wooden components on the site. The production of siege equipment in ancient times was not complicated, so it could be done like this, which greatly reduced the burden on the army when marching.

Huang Yueying said: "Although it is more complicated than ordinary catapults, I think it is completely fine to make it on site like an ordinary catapult. In terms of production cost, since the iron components are more than ordinary catapults, the cost is relatively higher, and there is nothing else." Ailang was very happy when he heard this. Looking at the huge earth and stone cart like a hill, I couldn't help but murmur excitedly: "If I use this catapult to hit Xuchang, my bastard father-in-law would definitely be shocked!" Huang Yueying couldn't help laughing and gave Ailang a blank look.

Ailang said excitedly: "Yueying, are there any other equipment? Let me be surprised!"

Huang Yueying seemed to want to say something, but changed her mouth and said, "No more for the time being!"

Ailang couldn't help laughing and said, "I thought you were Doraemon, and the energy source kept bringing out strange things!" Huang Yueying blinked and asked in confusion: "Husband, what is this Doraemon?" Ailang uh, laughed and clenched his head, "That, it's actually a very magical boy I've met in the past. He can bring me a surprise every day!" Speaking of this, Ailang couldn't help but reveal a look of memories. He recalled the joy and excitement when he was a child when he was a child. When Huang Yueying heard Ailang's words, she couldn't help but frowned, and was a little dissatisfied with the Doraemon guy. She couldn't help but make up her mind to surpass that guy and let her husband know that he was the best!

Ailang and Huang Yueying returned to the gate of the mansion. Huang Yueying suddenly remembered something, screamed, and said hurriedly: "I forgot the date with Sister Xiao and Sister Zhen Mi!" Then he said to Ailang: "Husband, I want to go to Sister Xiao's house, you go back first!" After that, without waiting for Ailang to answer, he led his maids to the residence of Xiao and Zhen Mi.

Seeing her look in a blazing mood, Ailang couldn't help but smile.

As soon as he entered the gate, a personal soldier immediately rushed up and bowed, "General, Mr. Chen Gong is waiting in the hall." Ailang immediately walked into the hall. As soon as he entered the hall, he saw Chen Gong sitting upright behind a short table drinking tea, while a middle-aged man with dark skin but temperamental poetry stood behind him.

"Old Chen!" Ailang greeted.

Seeing Ai Lang coming back, Chen Gong quickly got up and paid homage to Ai Lang: "General!" The middle-aged man also followed Chen Gong to pay homage to Ai Lang. Chen Gong quickly straightened his waist, pointed to the middle-aged man behind him, and smiled and said, "This is a sea merchant sent from Xia Pi. The family of three generations has traded with the Japanese!" The middle-aged man quickly paid homage to Ai Lang: "Grandman is sophisticated, pay homage to the general!"

When Ailang heard this name, he couldn't help but say jokingly: "This name is so good!" Gao Shen smiled, "The grass people are helpless because of their parents!"

"Well. Do you know why I called you here?"
