Immediately, Lu Chen returned to Lu Mansion and began to explore the production of this black powder. www.biquge.info he first wrote down all the production processes he could think of on paper. Although for the detailed process, Lu Chen is not clear. However, as long as it is mixed according to the ratio of one nitrate, two sulfur and three charcoal, it is fine.

After writing the production process, Lu Chen arrived again and came to the house. Although there is no sulfur yet, Lu Chen first sifted the charcoal and saltpeter.

At dusk, Song Cai finally sent someone to deliver the first batch of sulfur. It's just a few ores rich in sulfur, but that's enough for land dust.

Lu Chen first sifted the sulfur, and then mixed the three ingredients together according to the proportions. In the end, Lu Chen made a shell for the black powder mixed together.

After a while, Lu Chen took the black bomb he had just made, carefully observed it for a while, and when he felt that there was nothing wrong, he made another one.

After making the second bomb, Lu Chen rushed out of the city with two bombs. When he came to a wooded area and made sure that there was no one around, he carefully dropped one of the bombs on the ground and ignited the gunpowder letter with flint.

Igniting the bomb, Lu Chen hurriedly hid in the distance, he hid behind a tree and quietly watched Xinzi burn out. However, the black bomb did not react in the slightest.

The puzzled Lu Chen slowly walked forward, only to see that the black ball was still in place and did not react at all. Seeing this scene, Lu Chen walked over with a light sigh, wanting to check what the problem was.

However, as soon as Lu Chen picked up the bomb, he heard a soft pop. Lu Chen only felt a flash in front of him, and he subconsciously closed his eyes. When he opened his eyes again, he saw that the clothes on his body had turned black at this time, not only the clothes, but even his hands and even his face were blackened by the moment just now.

Seeing this, Lu Chen could only helplessly throw away the remaining black shell in his hand. Apparently because the bomb was not completely sealed, all the gunpowder turned into sparks and did not explode.

At this time, Lu Chen, who was dressed in pitch black, took out another bomb and put it on the ground, and carefully lit the letter again. After seeing that it was ignited, Lu Chen immediately ran into the distance. However, he had not been far away when he heard a loud bang behind him. Hearing this sound, even if he didn't look at the scene behind him, he knew that it was most likely a success.

Lu Chen turned around and looked, and sure enough, in the original block, a soil pit of about five or six meters appeared. Although the pit is not very big, Lu Chen is already very satisfied. After all, there was not a lot of gunpowder in the bomb just now, so the power after the explosion was not very great.

After seeing the success of the bomb he made, Lu Chen swept away the disappointment on his face, and he immediately walked towards the mansion where the raw materials were piled up.

When he came to the mansion, Lu Chen taught the production method to a few people who guarded the yard and asked them to help him make bombs. After having this killer feature, Lu Chen finally has a certain confidence in this war.

He believed that with these bombs made of black powder, even if they couldn't kill many people, they could at least disrupt the opponent's formation. When the time comes, the army of the Shannan West Dao Jiedu Envoy will rush up again, and the army of Yizhou Taishou will definitely be defeated in an instant.

However, the number of bombs needed for this battle is certainly quite large, at least in the thousands. And there are less than ten people in this house, even if they make it quickly, it is estimated that they will make one or two hundred pieces a day, and if they want to accumulate a few thousand, they will have to wait at least ten days and half a month. But now the decisive battle between the Yizhou Taishou and the Shannan West Dao Jiedu envoy is about to break out. And once the decisive battle occurs, the winner will soon be decided, and then Lu Chen must even arrive and help. Otherwise, once the Shannan Xidao Jiedu envoy is completely defeated, Lu Chen will not be able to save the battle even if he goes.

Thinking of this, Lu Chen immediately called over a person who was making a bomb and said, "You go to Song Cai and ask him to send back five or six people." Remember, these people must be faithful."

A moment later, the man who had left before led the eight people back. With the addition of these eight people, their production process has also been much faster. After all, making a bomb out of black powder is very simple, and there is no complicated process. So, in this evening alone, they had already made nearly a hundred bombs.

Looking at the bombs piled up in the yard, Lu Chen repeatedly warned, "You must not bump these things, and besides, these bombs must be kept away from the fire, otherwise your lives will be in danger" It was not until he saw that they all realized the danger of these black balls, and then Lu Chen left this place. After all, none of these people have seen a bomb, in case anyone can't help but be curious and light one, Lu Chen estimates that this piece of mansion does not exist.

In order to prevent accidents, Lu Chen had already instructed them to transport every hundred they made out of the city, and then find a hidden place outside the city to store them. Otherwise, once thousands of bombs explode in Chang'an City, it is estimated that one-third of Chang'an City's urban area will be flattened by it in an instant.

As for the soldiers who were inspecting at the city gate, Lu Chen was not worried. Because these people didn't know about bombs, it was impossible to keep them.

After Lu Chen returned to Lu Mansion from here, he opened the map he had bought with a lot of money again, and began to study the river where the two sides were facing each other and the terrain around it. Lu Chen had to find a place suitable for a sneak attack, otherwise, he would not be able to cause great casualties to Yizhou Taishou at all.

Because the Jialing River is located in the southwest of the Tang Dynasty, there are many mountains and rivers around. If you add those small hills and rivers, you can say that there are small hills and rivers everywhere.

Seeing such terrain, Lu Chen's heart was also slightly relieved. With these hills and rivers, it was still easy for his thousand people to hide. And next to the river where the two sides are facing each other, the large and small mountain ranges are even more layered.

Lu Chen found two mountain ranges next to the river, the mountains were not very large, but they were very close to the location of the decisive battle between the two sides. Sneak attack from the back of that mountain range, Lu Chen believed that the Yizhou Taishou would never think of it. The only trouble is that when they pass through the mountain range, they will definitely encounter those poisonous insects and beasts, and when the time comes, Lu Chen's manpower will definitely have casualties.

Thinking of these poisonous insects and beasts, even Lu Chen felt a little helpless. For poisonous insects, he may be able to find some herbs, and the smell of herbs can smoke away poisonous insects. However, for those fierce beasts in the forest, Lu Chen had no choice. Those beasts of prey are not something that can be smoked away by the slightest smell.
