Ma Jun's face was flushed, and his gray hair was trembling, belittling his inventions and creations was like insulting his personality, which Ma Jun could not accept under any circumstances.

Ma Jun's temper is really like a donkey, and he dared to fight Gao Tanglong and Qin Lang in the court, who were higher than his official positions, because Gao Qin and the others repeatedly denied his skills.

In Ma Jun's view, it doesn't matter if you are an official or not, your skills must not be insulted.

Cao Liang's words were simply about to poke into his heart, this was the hard work he had studied for half his life, and he actually got Cao Liang's bad evaluation.

It's bearable, it's unbearable, uncle can bear it, and aunt can't bear it!

"You...... Megalomaniacal Boy...... Honest and untrustworthy! Ma Jun's eyes were a little red, and he looked at each other angrily.

Fu Xuan really regretted showing the drawings to Cao Liang at this time, Ma Jun's temper was very clear to him, once he was angry, he would have to remember a lifetime of hatred.

"Brother Cao, can you really understand this drawing? Even if you can understand it, there is no need to denigrate Mr. Ma's achievements so much, in my opinion, there is no better stone truck designed by Mr. Ma in this world. Fu Xuan complained.

Cao Liang put his hands on his back and looked up to the sky and smiled, and said: "I have heard for a long time that Mr. Ma is a skilled craftsman in the world, and when I see it today, it is not more than Er'er, his eyes are rude, and the frog ears at the bottom of the well are really better than not seeing each other, and I have taken my leave." ”

Ma Jun stretched out a hand, grabbed Cao Liang's wrist, and said sharply: "Boy, you ...... today If you don't name a ugly man, Hugh ...... Don't want to leave! ”

Cao Liangqi said: "Didn't Mr. Ma accept outsiders before, why do you want to stay here now?" ”

Ma Jun said angrily: "Less...... Less nonsense, you say me...... My stone cart can't work, you can get it...... Make a good one to see ......."

The more angry Ma Jun became, the more he seemed to stutter, and Cao Liang laughed for a while, no wonder Ma Jun couldn't argue with others in the court, at his level of speech, the dumplings were boiled in the teapot, and he couldn't pour them out.

Originally, Cao Liang was going to treat Ma Jun with each other in order to gain his approval, but he didn't expect that this old guy was a stone in the pit, smelly and hard, and he said a lot of good things, but he still loved to ignore it, so Cao Liang had a plan, and he didn't play cards according to common sense, so he picked on him first.

To deal with such a strange-tempered person, it is natural to use some extraordinary means.

Although Ma Jun's skills are unmatched in this era, Cao Liang is not a person of this era, he can easily throw Ma Jun up ten streets with a little thing.

Of course, Cao Liang understands, it's just a superficial thing, really let him build a catapult now, that is purely a test to climb to the sky, but Cao Liang is not too worried, he only needs to throw out some theoretical things, which is enough for him to doubt life.

Cao Liang said unhurriedly: "Mr. Ma, judging from your drawings, the range of the chain thunderbolt you made should not exceed one hundred and twenty steps, and the number of drags that need to be pulled must be at least two hundred and forty people, while the effective range of an ordinary bow and arrow is one hundred steps, the maximum range can also reach one hundred and twenty steps, and the effective range of the bed crossbow is more than one hundred and fifty steps. Excuse me, how can such a huge target evade the blows of the opponent's bow and arrows and bed crossbows? ”

Ma Jun pondered for a while, to be honest, Ma Jun belongs to the technical nerd, he is good at studying mechanical weapons, and he is not good at arranging troops and skillfully using various instruments and weapons, when he is studying trebuchets, he thinks about the efficiency of the trebuchet itself, and as for the battlefield application, he naturally thinks much less.

"You can take advantage of ...... Use shield soldiers as cover......" Ma Jun said vaguely.

Cao Liang smiled and said: "Mr. Ma, when attacking the city, our side is attacking from the back, and the enemy is attacking from below, at this angle, even if the shield soldier raises the shield above his head, he can only barely protect himself, how can he still have the strength to protect the trebuchet?" ”

Ma Jun frowned, he had never participated in actual combat in his life, so he naturally didn't know much about the coordinated operations between various arms, and in terms of trebuchets alone, if they were exposed to the threat of enemy bows or heavy crossbows, the possibility of being destroyed was very great.

"That'...... Then reduce the weight of the stones, so that you can ...... You can increase the range. ”

The maximum weight of the stone thrown by the chain thunderbolt is 30 catties, and the range at this time is 120 steps, if the stone is reduced to 20 catties, the range can be increased by 30 or 40 steps to more than 150 steps, and if the weight of the stone is further reduced, the combat distance of the stone can be increased again.

But the lighter the stone and the longer the range, the less powerful the trebuchet will be.

Cao Liang hit the nail on the head: "Thirty pounds of stones, barely able to shake the city wall, twenty pounds of heavy stones, smashed on the city wall, I'm afraid it is difficult to have power, to the bottom of more than a dozen pounds of stones, Mr. Ma, don't you really want to tickle the city wall?" ”

Ma Jun was suddenly speechless, this time it was really not caused by his stuttering, but Cao Liang's words hit the nail on the head, exposing the shortcomings of the trebuchet, leaving Ma Jun speechless.

Even Fu Xuan was shocked, originally thought that Cao Liang didn't know anything about trebuchets, but he didn't expect Cao Liang to be honest and ask Ma Jun to stop, Fu Xuan said that he was too surprised.

Cao Liang sneered twice and said, "Mr. Ma thinks that with such a drawing, what is the chance of persuading the general?" In my opinion, the general may have abandoned it. ”

Ma Jun is probably really a little skeptical about life now, and even he didn't expect that he had studied trebuchets for most of his life, and he was actually denied by others in a few words.

He had always been indignant about what happened to him before, thinking that his invention was not valued by others, and now it seems that it is not entirely someone else's factor, and his own things are still very flawed.

"How's that ...... How can you convince the general? Ma Jun muttered.

Fu Xuan also said: "Since Brother Cao knows the shortcomings of the trebuchet, there must be a way to solve it, and I hope to give him advice." ”

Cao Liang sold Guan Zi at this time: "Is there a way, it's not that there is no ...... It's just that I've been talking for a long time, my mouth is dry, and it's past noon, and I'm hungry, so it's better to find a place to solve my appetite first, and then study it another day when I'm free? ”
