Ma Jun's face turned red, and his gray beard and hair were trembling. To belittle his invention was to insult his personality. Ma Jun could not accept this at any cost.

Ma Jun's temper was like a stubborn donkey. He dared to fight with Gao Tanglong and Qin Lang who were higher than him in the court because they repeatedly denied his skills.

In Ma Jun's view, it doesn't matter whether he is an official or not. His craftsmanship cannot be insulted by others.

Cao Liang's words were about to pierce his heart. This was the painstaking effort he had spent half his life studying, and yet he actually received a distasteful evaluation from Cao Liang.

It is bearable, but which one is intolerable? My uncle can bear it, but my aunt cannot bear it either!

"You... arrogant boy... talk nonsense!" Ma Jun's eyes turned red and he glared at each other.

At this time, Fu Xuan really regretted showing the drawings to Cao Liang. He knew Ma Jun's temper very well. Once he angered him, he would bear a lifelong grudge.

"Brother Cao, can you really understand this drawing? Even if you can, there is no need to denigrate Mr. Ma's achievements so much. In my opinion, there is no stone-making cart designed better than Mr. Ma in this world."

Fu Xuan complained.

Cao Liang put his hands behind his back and looked up to the sky with a smile and said: "I have heard for a long time that Mr. Ma is a skilled craftsman in the world. When I saw him today, he was just a little bit. His eyes were vulgar and he had the ears of a frog at the bottom of a well. It's better not to see each other than to see each other. I'll say goodbye."

Ma Jun stretched out a hand, grabbed Cao Liang's wrist, and said sternly: "Boy, today you... don't tell me that you are Chou Yinmao, don't... don't even think about leaving!"

Cao Liang asked curiously: "Didn't Mr. Ma not tolerate outsiders before? Why do you force him to stay here now?"

Ma Jun said angrily: "Stop... stop talking nonsense, you said that I... my stone machine is not good, you can... make a good one..."

The angrier Ma Jun got, the more he seemed to stammer, which made Cao Liang laugh for a while. It's no wonder that Ma Jun couldn't argue with others in the courtroom debate. With his level of speaking, he couldn't pour dumplings out of a teapot.

Originally, Cao Liang was going to treat Ma Jun kindly to gain his approval, but he didn't expect that this old guy was like a stone in the pit, smelly and hard. He said a lot of nice things, but he still ignored him, so

Cao Liang had a plan in mind, not to follow common sense and to find fault with him first.

Naturally, some extraordinary measures must be used to deal with such a weird-tempered person.

Although Ma Jun's skills are unrivaled in this era, Cao Liang is not from this era. He can easily throw Ma Jun across ten streets with just a few things.

Of course, Cao Liang understands that it is just a superficial matter. If he really wants to build a catapult now, it would be a pure test to reach the sky. However, Cao Liang is not too worried. He only needs to throw out some theoretical things.

Come, it's enough for him, Ma Jun, to doubt his life.

Cao Liang said calmly: "Mr. Ma, judging from your drawing, the range of the chain thunder car you made should not exceed 120 steps, and the hand that needs to be pulled should be at least 200 steps."

Forty people. The effective range of ordinary bows and arrows is one hundred steps, and the maximum range can reach 120 steps. The effective range of crossbows is more than one hundred and fifty steps. The chain of thunderbolt chariots wants to reach the siege position.

, it must be advanced within a hundred steps of the city. How can such a huge target avoid the strikes of the opponent's bows and arrows and crossbows?"

Ma Jun pondered for a moment. To be honest, Ma Jun is a technical geek and is good at researching mechanical weapons. However, he is not good at arranging troops and skillfully using various equipment and weapons. When he was studying the trebuchet, he considered the most.

Well, it was still a matter of efficiency of the trebuchet itself. As for battlefield application, he naturally considered much less.

"You can use...the shield soldiers as cover..." Ma Jun said vaguely.

Cao Liang chuckled and said: "Mr. Ma, when we attack the city, we attack from above and the enemy attacks from below. At this angle, even if the shield soldiers raise their shields above their heads, they can barely protect themselves. How can we still protect ourselves?"

Do you have enough energy to protect the trebuchet?"

Ma Jun frowned. He had never participated in actual combat in his life. Naturally, he did not know much about the coordinated operations between various arms. For a trebuchet alone, if it was exposed to the threat of enemy bows and arrows or heavy crossbows, it would be destroyed.

The possibility of destruction is high.

"Then... then reduce the weight of the rocks, so that... you can increase the range."

The maximum weight of the stone thrown by the serial thunderbolt car is thirty kilograms, and the range at this time is one hundred and twenty steps. If the stone thrown is reduced to twenty kilograms, the range can be increased by thirty or forty steps accordingly.

After reaching more than 150 steps, if the weight of the stone is further reduced, the combat distance of throwing the stone can be further increased.

But the lighter the thrown stones and the farther the range, the more the power of the trebuchet will decrease. What value does a trebuchet without power have on the battlefield?

Cao Liang hit the nail on the head: "A stone weighing thirty kilograms can barely shake the city wall. A stone weighing twenty kilograms will probably have no power if it hits the city wall. A stone weighing ten kilograms can barely move the city wall.

, Mr. Ma, don’t you really want to tickle the city wall?”

Ma Jun was immediately at a loss for words. This time it was really not his stuttering, but Cao Liang's words that hit the mark and exposed the shortcomings of the trebuchet, leaving Ma Jun speechless.

Even Fu Xuan was shocked. He originally thought that Cao Liang knew nothing about trebuchets, but he didn't expect that Cao Liang actually spoke eloquently and stopped Ma Jun from asking questions. Fu Xuan said that he was too surprised.

Cao Liang sneered twice and said: "Mr. Ma, what are the chances of convincing the general by bringing such a drawing to the general? From my perspective, the general will probably abandon it like worn out shoes."

Ma Jun is probably really doubting life now. Even he did not expect that the trebuchet he had studied for most of his life would be denied by others in just a few words.

He had always been aggrieved about his own experiences before, thinking that his inventions and creations were not valued by others. But now it seems that it is not entirely other people's fault. His own things still have great flaws.

"Then how...how can we convince the general?" Ma Jun murmured.

Fu Xuan also said: "Since Brother Cao knows the shortcomings of the trebuchet, he must have a way to solve it. I hope you will give me some advice."

At this time, Cao Liang started to talk about it: "Is there any way? It's not that there is nothing... I just talked for a long time and my mouth is dry. It's past noon and I'm hungry. Why don't I find a place first?"
