When I came to the outside of the Science and Technology Institute, I saw that the Science and Technology Institute was heavily guarded, and there were soldiers of the Dragon Guard Army standing guard and patrolling inside and out, and it was forbidden to enter and exit.

"My lord..." The soldiers saluted.

"Stand guard well, don't be negligent."

"No."

Lu Bu came in person, and Zhang Feng led the way, so it was unimpeded.

When I came to the square inside the Science and Technology Institute, I saw a lot of strange things.

Ma Jun rushed over when he heard the letter and said, "Lord... Lord, how do you kiss... Personally came. ”

"I'll take a look at your science and technology institute, how is it doing. I've heard that you've developed a lot of new siege weapons, but where are they? ”

"My lord, please."

Ma Jun led the way and brought Lu Bu, Chen Gong, Xu Shu, and Zhang Liang to the northwest corner of the square. There were a lot of siege equipment placed there, and everyone was amazed when they saw it.

"How are these things used?" Chen Gong asked.

Ma Jun introduced: "The first... The first is an automatic ladder. High two... Two zhang, weighing three hundred... Three hundred and fifty pounds. Push the ladder... Push it to a foot away from the city tower... a distance of one zhang, and then turn... Turn the wheel, and the first and second ladders will rise up and take them up to the castle tower. He... The good thing about him is that the soldiers are in... In the process of climbing, down, down... The distance below is two zhang away, and it will not be affected by... Under attack from the enemy, because... Because the back of the ladder is used... With iron sheets... Wrapped, bow ... Bows and arrows cannot penetrate. And on... A long distance from above, the ladder is... It's solid, and the soldiers can... You can run very quickly... Run, run to the tower. If the enemy doesn't... If you don't pay attention, a... In the blink of an eye, we, our taxis... And the soldiers went up to the city. ”

Ma Jun stumbled and finally finished introducing the first thing.

"Good, good...!" After listening to this, Lu Bu highly appreciated it.

"Thanks... Thank you. ”

Ma Jun continued: "The first... The second type is the pumping machine. OK... Can be erected on a moat, soldiers... The soldiers stepped on the roulette, and the river ... The water in the river, the water will... It's going to be pumped up, and it's going to be along this one... This pipe, sprinkled... Sprinkle anywhere. Humble... I know, our siege troops... It is very easy to be burned by fire oil, and there are... With this pumping machine, it's... Don't be scared anymore. Whereas... And his use, no... Not just for siege cities, but also... It is possible to irrigate crops.... ”

It was hard for everyone to listen, but they understood it.

"Good stuff." Chen Gong, Zhang Liang, and Xu Shu all praised Ma Jun vigorously.

"Many... Thank you for your appreciation, you... As long as you are satisfied, humble... Humble duty is relieved. Ma Jun said with a smile.

"It's a three-bow crossbow, right?" Lu Bu walked up to a device and asked.

"Yes.. Yes, how does the lord know, I just... I just finished picking a name. Ma Jun looked surprised.

Lu Budao: "Your instrument, the three bows overlap, the power is huge, it's not called a three-bow crossbow, what is it called." ”

"Lord... The lord is wise. Ma Jun introduced: "Three... Three-bow crossbow, can shoot 400 paces away, can... Pierces and pierces enemy armor. But... He's too heavy to carry, so he can only ... Can only be used for siege and fortification. No... It is not conducive to field and field operations. ”

Lu Bu called a team of soldiers and experimented with all three instruments. It's all the same as Ma Jun said, there is no discrepancy.

"Ma Jun."

"Yes."

Lu Bu said with a smile: "I really didn't misunderstand you, it only took a year of hard work to run the Science and Technology Institute so well, and also developed three powerful siege equipment, I must tell the Ministry of Rites and give you a heavy reward." ”

"Thanks... Thank you. ”

Lu Budao: "But I think you are all petty fights, at best... That is, on the basis of the original, it has been strengthened a little, and I hope that you can develop more powerful weapons. ”

"Lord... Lord, what is more... A more powerful weapon, huh? Don't... Could it be that these are still... Isn't it good enough? "Ma Jun didn't understand.

"It's amazing, but I need more than that, I need..." Lu Bu couldn't say clearly for a while, and ordered: "In this way, you organize a department, take some of the medicines from the Tai Hospital, and then mix two or three kinds together, light them with fire, and see what the reaction is." If you can generate a huge amount of energy and cause an explosion, then you have succeeded. But it's dangerous, and you'd better send your men to do it. ”

"Yes."

Ma Jun still didn't understand, but he remembered the steps Lu Bu said.

"Next, the Academy of Science and Technology will do two things. First, mass production of automatic ladders, pumping machines, and three-bow crossbows. Second, the test drug. Keep me informed of any progress. ”

"Yes."

Until Lu Bu left, Ma Jun still hadn't figured out what the research of powerful weapons had to do with medicine?

Back in the Assassin's Mansion, Xu Shu asked, "Lord, are you going to study poison?" ”

Burst...

Lu Bu took a sip of tea and said, "Who told you to study poisons." I mean gunpowder. Do you know about gunpowder? It is mixed with some drugs, and when it is ignited, it will explode. ”

Chen Gong looked confused.

Xu Shu and Zhang Liang looked at each other.

Xu Shu said: "The explosion caused by drugs is only saltpeter." Is the lord talking about saltpeter? ”

Saltpeter?

Lu Bu didn't know exactly how to make gunpowder, but the word saltpeter reminded him of this. Immediately rejoiced: "That's right, it's saltpeter!" But... How do you know? ”

Xu Shu said: "Hui Zhugong, according to the record in "Fan Zi Yeran", during the Spring and Autumn Period and the Warring States Period, there were people who used saltpeter, and when saltpeter rubbed or collided with hard objects, it was possible to burn or explode. ”

"Yuan Zhi is really full of talent, admire!"

"Don't dare, don't dare..."

Lu Budao: "You go to the Academy of Science and Technology again and tell Ma Jun to let him mix and burn with other drugs on the basis of saltpeter until it can cause an explosion, even if he has developed gunpowder." ”

"Yes."

Xu Shu left quickly.

Lu Bu was also very helpless in his heart, he only knew that the ingredients of gunpowder were three kinds of medicinal materials, but he was not very clear which three they were. If you can study hard when you are young, you won't be entangled anymore.

"My lord, the minister has also retired." Zhang Liang said politely.

"Well, go and discuss with He Shen and run the school as soon as possible."

"No."

After Zhang Liang left, Lu Bu and Chen Gong were left.

Chen Gong said: "General Luo and General Fan both recommended Bai Qi and Liang Hongyu to me, who have the talent to lead an army alone. And in last year's war, they made a lot of contributions to their establishment, I don't know what the lord's opinion is? ”
