The loud bang made the soldiers guarding outside the test site dare not rush in.

When they came in, they saw three people lying on the ground - Yan Ming, Wei Qing, and Han Yan.

"What happened?" Wang Dajian, who was the leader, scratched his head, looking at the smoke and dust that had not yet dispersed in the distance, as well as the broken flesh and blood in that place.

Originally, the chickens, ducks, cattle and sheep were all brought by them and placed in the test ground. Now, all the living creatures have fallen.

See the smoke and dust that slowly dissipate, and then look at the dead things on the ground. No matter how stupid these people are, they can understand that it was a loud bang just now that killed all those livestock.

The soldier came in, Yan Ming also stood up, patted his clothes, looked at the creatures on the ground in the distance, or were still alive, and said in a deep voice, "Come with me to check." Those who are still alive are sent to the biological garden in Hongyan Hall, and no one is allowed to hunt them, so that they can be raised alive, and they are buried after death, and they are not allowed to eat. ”

"No!"

Everyone replied respectfully, but they didn't know why Hou Ye cared so much for those animals that didn't die.

Even Wei Qing and Han Yan didn't understand Yan Ming.

Yan Ming didn't need them to understand, among these creatures, except for Li Shaojun, none of them deserved to die. Now they are dedicated to the first test for the sake of the military strength of the Great Han. Those who didn't die were lucky, and Yan Ming wanted to give these surviving animals a pension.

On the ground, an iron ball bomb blasted a pit half a meter wide.

From afar, there were some pieces of broken iron stuck in the deep pit.

Three paces away from the edge of the pit, a corpse in heavy armor was no longer visible.

One arm was missing, and the leg was blown to pieces. The junction between the neck and the body was also blown open and bent to the side.

The heavy armor on his body was scattered by iron sheets. Blood gushed from under the heavy armor. Even half of the intestines fell out.

Li Shaojun is already dead.

Seeing Li Shaojun's death, even these soldiers who had seen the big battle couldn't help but feel a little disgusted. Yan Ming retched a few times and forcibly held back.

The chickens, ducks, cattle and sheep on one side were killed and wounded. In particular, most of the chickens, ducks, cattle and sheep near the explosion zone were mutilated and died in extremely miserable conditions.

"Clean up!" Yan Ming couldn't bear to look at it anymore and turned to leave.

"That Li Shaojun, let's also bury it." Yan Ming added. Although it is not a pity for this guy to die, he can test it before he dies, which can be regarded as forgiveness. Give him a good burial, and hope that he will be a good person in the next life.

Han Yan's already white face now looks even whiter. Wei Qing can't forget the scene just now. This kind of iron ball, before the experiment, none of them expected that it would be so powerful.

"In the evening, please eat meat!" In order to alleviate the embarrassing situation, Yan Ming made a vulgar joke.

"Vomit-" Hearing the meat, Han Yan covered her mouth immediately.

Wei Qing's face was not good-looking, but it was not as obvious as Han Yan.

"Yan Ming, if you dare to talk about meat again, I will break off my friendship with you." Han Yan retched for a long time, but she said a meat word and retched for a while.

Yan Ming couldn't help but shake his head and sigh, the ancients who hadn't seen the bloody blockbuster just had no resistance. When I saw it myself, I did feel a little sick. But it doesn't make the mention of meat disgusting.

"Okay, let's not mention it." Yan Ming walked first.

Han Yan snatched it in one step, grabbed the corner of Yan Ming's clothes and said, "What you got just now, you must explain it to me clearly." ”

Yan Ming raised one finger and silenced his mouth, and then whispered, "This is a big killer." Now it's a state secret. If you leak it out, Your Majesty will definitely cut off your head. ”

Han Yan pushed him angrily, but the retching just now made him a little weak. was gently dodged by Yan Ming.

"Will Lao Tzu leak secrets?" Han Yan scolded.

"It's good that it won't leak secrets, and you can tell the emperor about it tomorrow. So I asked him to see the power of this thing. Yan Ming smiled.

"What? Let me run errands for you back to Chang'an? Han Yan pursed her lips and said.

"I didn't let me, didn't I see my third brother coming, he is now in the name of General Xiaocai, leading the army of the captain of the Hu cavalry." Yan Ming said.

"Damn, when you go to the border, you let me go back to Chang'an. Or should I be a brother? What's more, your thing is so powerful, how can I not go to the border to take a look? Han Yan kicked Yan Ming and said indignantly.

Yan Ming flexibly dodged Han Yan's kick and said with a smile: "I didn't mean to let you go back to Chang'an. This is what His Majesty said. ”

"You wait, I'll go back and tell Your Majesty. Even if I resign, I will go to the border. Han Yan gritted her teeth and said.

Wei Qing and Han Yan didn't mention Yan Ming's shock of the iron ball bomb, and they didn't mention the handover of the military.

Speaking of Yan Ming alone, after this experiment, it was found that this iron ball bomb still has an obvious shortcoming. It's a matter of leads.

If the lead is too long, it may go out when it hits the ground and will not explode. When facing the enemy, there are more variables. In order for the iron ball bomb to explode accurately, it also needs accurate measurement calculations.

And those sulfur and saltpeter at the bottom of the eastern valley are simply treasures given to him by heaven.

These things must be brought back and made into black powder.

Just to make gunpowder, you must have a safe environment. When you think about it, there's so much to do.

Although there is no gunpowder, you can make as many hollow iron balls as possible to make iron ball bombs. These cast iron balls do not need good iron, they only need to be cast. It can be prepared in the hundreds, if not thousands, and once the gunpowder is ready, it can be loaded, and then it will be a lethal bomb.

If the Huns dared to attack, they would use these things to attack them head-on.

Of course, these iron ball bombs were prepared by Yan Ming for the large army of the Huns. If you encounter a small group of Xiongnu besieging the city, you can completely suppress it with military crossbows.

The next day, when Yan Ming was still experimentally measuring the burning time of the lead, Han Yan had already set off with Yan Ming's recital.

Yan Ming knew that Liu Che was coming.

Before Liu Che came, he wanted to make the iron ball bomb more fine.

While experimenting with the lead length of the iron ball bomb, he instructed the elder Chen to try to cast all the edges and corners of the iron ball when casting the hollow iron ball.

Cast iron is inherently brittle and prone to chipping. Now that edges and corners are added to the surface, they will naturally break along the edges and corners, so there is no need to add broken iron pieces or the like to it separately.

The two of them performed their own duties, and they were in full swing to make this simple murderous weapon.

In Chang'an City, Liu Che saw Han Yan, and before he had time to reminisce, his jaw was almost off hook when he was shocked by the news brought by Han Yan.

What can blow the earth out of a crater with a loud bang?

What can kill a large number of creatures with a single flash of fire?

The Han Dynasty had this thing, what would it be like if they could be thrown into the cavalry of the Huns?

Thinking of this, Liu Che's fart. The stock couldn't sit still any longer, no matter if Han Yan had just returned from Maolingyi, he immediately dragged him back to Maolingyi.
