With the materials, it is much easier to configure black powder, and the only thing that needs to be paid attention to is to master the ratio of the three materials.

Soon, the first gunpowder was configured, and Ye Xiao decided to test its power to determine whether the configuration ratio was appropriate.

Wrapped the gunpowder powder in the animal skin, Ye Xiao took it to the outside of the cave, and put it in a place selected in advance, and Ye Xiao put a big stone on the animal skin explosive package.

Ye Xiao took out a lead made of hay leaves, inserted it in the medicine bag, and after looking at the fact that there was no one around, Ye Xiao lit the lead and then hid in a low-lying area next to it.

The lead made of hay leaves was also filled with black powder, so the burning speed was very fast, and Ye Xiao didn't have long to hide in the low-lying area before he heard a roar.

"Boom."

The animal skin bag exploded, the snowflakes on the tree were shaken, and after confirming that it was safe, Ye Xiao walked over and observed, because it was just for experiments, so Ye Xiao didn't put a lot of gunpowder, so the power was not very great.

The explosion point was scorched black by gunpowder, the stones covering it were blown loose, and a small pit was blown out on the ground.

The power of this explosive is still in line with their expectations, which means that the proportion of their configuration has not deviated much, and they only need to improve it.

Next, Ye Xiao and the ghost doctor conducted several more test explosion experiments, and finally determined a better configuration ratio, but the potassium nitrate and sulfur collected before were almost used, so they could only wait until enough materials were collected again before configurement.

During this period, the people of the Kunshan tribe and the warriors training at the foot of the mountain heard the explosion from the back mountain from time to time, and they were very puzzled, not knowing why such a huge noise came from the back mountain.

But because the road to Houshan was guarded by Ye Xiao and Lan Heng, they could only give up the idea of going to join in the fun.

After Lan Heng saw the power of this black powder, he was full of praise for it, and called Ye Xiao a god.

Lan Heng originally wanted to hold a bonfire feast to celebrate Ye Xiao and the others, but Ye Xiao refused, saying that now was not the time, and it was indeed not suitable for holding a party, seeing Ye Xiao's resolute attitude, Lan Heng had no choice but to give up this idea.

For the various weapons that Ye Xiao had recently created, Lan Heng only felt that he had lost his luck, and he had already decided in his heart that Ye Xiao was sent by the Yushen to help their Kunshan tribe rise.

As the leader of the Kunshan tribe, he knew very well what these weapons meant, and he believed that once they possessed these weapons on a large scale, their Kunshan tribe would be invincible in the future enemy.

In order to prevent the leakage of information, Lan Heng ordered the blockade of the Kunshan tribe, which strengthened the defense of the tribe, and no one was allowed to leave the tribe at will without permission.

Of course, except for those who were sent to the hot springs to collect sulfide and search for medicinal herbs, the hunting team was also hurrying to hunt, and everything was going according to plan.

After another month of training, the training of ordinary soldiers came to an end temporarily, Ye Xiao took out a group of people from it and trained them to use weapons other than gunpowder, because gunpowder was too dangerous and would explode if it was stained with sparks, so Ye Xiao did not let them use it.

Armed with crossbow arrows, crossbows, trebuchets, gunpowder...... These will be the trump cards of the Kunshan tribe in the future, and the Kunshan tribe is also seizing the time to make it.

A group of dragon beasts were hunted for tendons, and then used to make crossbow arrows, Ye Xiao formed a team of 100 archers, and on the training ground, a separate area was set aside for their training.

The ghost doctor is arranging gunpowder, and several other people also have their own tasks, and the task of training archers naturally falls on Ye Xiao.

Ye Xiao first trained them to use the basic movements of the bow and crossbow, and only after they could master it almost did Ye Xiao train them to shoot targets.

At this moment, in a corner of the training square, a row of arrow targets was erected, and fifty steps away from the arrow targets, a hundred archers were divided into five teams, and each twenty people were a small team, neatly arranged together.

"First Squad, Ready." Ye Xiao stood aside and gave orders.

The "Ka ......" twenty-person squad quickly loaded the crossbow arrows according to Ye Xiao's teaching, and prepared to shoot.

"Put!"

"Woo Woo ......"

With Ye Xiao's order, twenty crossbow arrows shot out quickly.

"Puff puff ......"

Some shots, some misses, and those who shoot are naturally happy, and those who don't shoot have bitter faces and are a little depressed.

"Remember what I told you about shooting, and come again." Ye Xiao was expressionless and ordered them to continue shooting, and after the first team shot ten arrows, Ye Xiao asked people to collect the arrows on the arrow target.

After the first team finished shooting, they consciously retreated and trimmed, and the second team waiting behind immediately stepped forward.

"Second Squad, Shoot Ready!"

……

On the arrow field, only Ye Xiao's command and archery sound were heard, in order to improve their archery skills in the shortest possible time, Ye Xiao prepared a large number of crossbow arrows for them, so the shooting on the arrow field has not stopped, and they will only have a little time to rest when each squad rotates to shoot.

Fortunately, they used crossbows, not longbows, so they didn't need to use much force.

One day was spent in training, and the next day was the same, and the hundred archers did not know how many crossbows they used every day, they only knew that they were repeating the same movements, and they were almost getting used to it.

The high-intensity archery practice made their archery skills rise rapidly, even if it was not as exaggerated as a hundred shots, but the effect also made Ye Xiao very satisfied.

One can imagine how overwhelmingly advantageous they will have in future battles with other tribes, with the help of these hundred archers.

In the eyes of outsiders, the Kunshan tribe has not made any moves in recent times, but they don't know that its strength is steadily rising.

All kinds of things are moving forward according to Ye Xiao's expectations, and Ye Xiao wants to believe that as long as he is given enough time, he will build a powerful army.

This is not arrogance, with bows, trebuchets and black powder, they are undoubtedly invincible here.

……

While Ye Xiao was training the warriors of the Kunshan tribe, Anderson was also training the warriors of the Heiya tribe on the other side.

His idea was similar to Ye Xiao's, that is, he wanted to use the modern training methods they had mastered to improve the combat effectiveness of the warriors of the Heiya tribe, so as to facilitate and better expand their strength.

But unlike Ye Xiao and the others, Anderson didn't think of making any trebuchets, crossbows and black powder here.

They are just carrying out the basic task of training soldiers, in fact, this is not to blame them, those things made by Ye Xiao are all weapons used in siege battles in ancient China, they have no ancient history, and people who are used to using modern means of warfare will not be able to think of these weapons used in the era of cold weapons for a while.
