Qin Lang even mocked Ma Jun's name and said:

"Mr. Jun's name is Jun, and his courtesy name is Deheng. Jun refers to the shape of the utensil, and balance can determine the weight of an object."

"Sir, you don't even know the weight and size standards of a compass, yet you dare to boast that you can make a compass. Don't you feel ashamed of your name?"

Ma Jun was born into a poor family, and his official position was too humble compared to Gao Longtang and Qin Lang.

Coupled with his stuttering, he was often looked down upon by others.

But there is a resilience in him, and he must do what he sets his sights on.

The three of them even got into trouble in front of Cao Rui. Cao Rui was very interested and ordered Ma Jun to build a compass.

After continuous attempts, Ma Jun finally succeeded in creating a compass car using the structural principle of differential gears.

This incident made Gao Tanglong and Qin Lang lose face, and at the same time, the reputation of Ma Jun's skill spread throughout the court.

It is a pity that Ma Jun's successful slap in the face did not bring him much benefit as he offended the senior ministers of the Wei Dynasty and the emperor's most trusted ministers.

After Cao Rui learned about Ma Jun's skill, he did not let him build more useful things.

Instead, he asked Ma Jun to create entertainment objects for himself.

Once, someone presented a puppet show to Cao Ruijin. The shapes were quite exquisite, but the puppets could only be placed there and could not move. Cao Rui felt quite regretful.

At this time, he remembered Ma Jun, who was known as a skillful man, so he summoned Ma Jun and asked:

"Can you make these puppets move?"

Ma Jun used wood to make a motive wheel, which was driven by water to rotate. Through the transmission mechanism, the puppets could play drums, play Xiao, dance, etc.

It is known as "Water Turns Hundreds of Plays" and its structure is extremely exquisite.

The creation of this fun thing made Cao Rui very happy, but Ma Jun's official career still made no progress.

Within two years, the Great War in Guanzhong broke out and Cao Rui died of illness. In the chaos that lasted for more than half a year, even Shangshu Ling Pei Qian disappeared.

Not to mention a little guy like Ma Jun.

If Cao Shuang hadn't ordered people to build the equipment used by the Han army according to the drawings, I'm afraid Ma Jun wouldn't be remembered for a long time.

"Good...good...good stuff!"

Although he had been left out for so long, Ma Jun's eyes lit up as soon as he got the drawings.

When he saw clearly the parts and assembled objects on it, he became even more excited.

It's just that he stuttered, and now he was a little incoherent when he was excited:

"Wonderful, wonderful, this thing is so ingenious, so, so true... It is so ingenious that it is as if it were made by heaven!"

Yang Yi, who was sent here, has been suffering from the warmth and coldness of the world these days.

At this time, someone finally saw the value of the drawings he sent. He was so happy that he almost shed tears.

What's nice is that someone believes in me, but what's sad is that this person is just a petty official, let alone a stutterer!

too difficult!

But at this point, he can only do his best to prove that what he has sent is worth thousands of gold, so that he can be valued by the general.

With this mentality, he fully assisted Ma Jun in building these instruments.

Among these things, Ma Jun valued the most, and that was the stone cannon.

After he successfully built it, he was still not satisfied, so he studied day and night to improve it, and finally created a new type of rotating stone cannon cart.

It uses a wooden wheel to hang stones on the wooden wheel. In this way, a machine is installed to drive the wheel to rotate quickly, and large stones can be launched continuously.

Although it is not as good as the large stone cannon, it is more portable, has a good range, and can be ejected automatically. If it can be popularized in the army, it will be a powerful weapon in the army.

After finishing the equipment, Ma Jun happily ran to Deng Yang to inform him of the result.

"You made it so quickly? Listen to Yang Yiyan, this kind of equipment is the secret of the Shu army. Did you just build something at random to fool me?"

Deng Yang looked at Ma Jun in front of him with some suspicion.

It's already the hot summer. Ma Jun has been immersed in research these days. Where does he have time to take care of himself?

Not only was the body dirty, but there was also a lot of sawdust on it, not to mention that when you got closer, there was a sour smell.

"Chang Shi, how dare I lie to you?"

When Ma Jun heard what Deng Yang said, he immediately became anxious.

He took two steps forward, as if he wanted to explain clearly, but the movement was a little wider, and the sour smell on his body immediately dispersed, causing Deng Yang to cover his nose:

"Stop, just stand there, I can hear you, what did you build?"

"Stone cannon!" Ma Jun waved his hands excitedly, "Shu's stone cannon is indeed powerful, but I have improved it and created a lighter and more useful stone cannon."

"Stone cannon?"

"Exactly, it's similar to the Thunderbolt Chariot used by Emperor Wu in the Battle of Guandu..."

Before he finished speaking, Deng Yang understood:

"Oh, I know it!"

Isn't it just that the Shu pirates secretly learned the Pili chariot from the past somewhere?

Yang Yi said that Shulu has been improved and is more powerful than the original Thunderbolt Chariot, which can hit rocks like thunder from the sky.

Now you say that it has been improved even more than Shulu?

For example, what is more powerful about Thunder Sky Drop?

God descends to earth?

Deng Yang smiled:

"Let me ask you, apart from the Thunderbolt Car, have you built any other objects?"

Ma Jun originally wanted to say that the thunderbolt chariot used by Emperor Wu was very different from the stone cannons made today.

But Master Changshi seemed to have decided that it was a thunderbolt car.

Okay, a thunderbolt car is a thunderbolt car.

Unexpectedly, Deng Yang looked like he didn't seem to pay much attention to this important weapon in the army.

He immediately became anxious:

"Deng...Deng...Deng...Chang Shi..."
