With Wei Chigong's deterrence this time, the Western Turks knew that the Tang Dynasty was making a locust plague, and they did not dare to attack easily, after all, Wei Chigong's pursuit of more than 30 miles did not seem to be a fraud.

After all, I haven't seen Datang's mysterious, explosive weapon.

The envoys who entered Chang'an were not only the Western Turks, but also Xue Yantuo, Tuyuhun and other envoys who entered Chang'an in the name of "friendly diplomatic relations" to inquire about "weapons that can explode".

However, they all failed, and they were even inferior to the Western Turks, because they had seen the arrow boxes on the Dragon's Tooth soldiers and guessed that they were weapons that could explode. But even so, they didn't get to see the scene of the thunderbolt being fired.

What is unknown is what is scary.

The Dragon's Tooth Army entered the Qinling Mountains with gunpowder weapons arranged by Tang Jian, and as a qualified diplomat, he achieved the ultimate in grasping people's hearts.

And Wei Chigong and Cheng Biting Jin, although they didn't catch the thunder arrow, they secretly gave them a thunderbolt when they set off.

Ground-level thunder!

In the small warehouse, Zhang Zhongqing saw this big guy.

Wuli Sima stood at the door of the small warehouse, as the emperor's direct officer, the daily management of the prefecture-level thunder was his responsibility, and he would not allow anyone to touch the ground-level thunder, including Zhang Zhongqing, the maker.

"Very good, there is no firewood in the storeroom, no open fire."

Zhang Zhongqing was very satisfied, it seems that this Wuli Sima has eaten his instructions thoroughly, and he is not stupid to the point of death.

Wuli Sima said expressionlessly: "Where the duty is, don't dare to be negligent, within a radius of 100 meters, no open flames are allowed to approach, otherwise, if the unequal level thunder is used to kill the enemy and blow up your own people, wouldn't it be unjustly killed." ”

Zhang Zhongqing nodded, and uncontrollably came up with the idea of developing fire prevention measures for gunpowder weapons, which were extremely flammable, if the enemy attacked them with fire.........

Wouldn't that be an apocalyptic disaster, and it would be devastating for the gunpowder weapons used against the enemy to exert their might in their own ranks.

As soon as this idea came to him, he couldn't stop the car, Zhang Zhongqing thought hard all night, even if the team had left the border and entered the territory of the Western Turks the next day, he still had no clue.

Seeing Zhang Zhongqing swaying on the horse and possibly falling off the horse at any time, Leng Feng couldn't help but slow down the horse, patted him and said, "What do you think, look at you, the dark circles under your eyes are out, and you haven't slept all night?" ”

Zhang Zhongqing rubbed his temples and said: "I'm thinking about how to make gunpowder weapons fireproof, think about it, if the enemy is not afraid of casualties and assault our barracks, as long as a rocket is fired into the warehouse where gunpowder weapons are stored, it can blow us up into the sky." ”

"It's easy." Leng Feng opened the arrow box on his back, took out a cloud-piercing arrow, pointed to the gusset that hid the fuse, and said, "As long as you optimize this place, so that there are not too many gaps between the gusset and the arrow shaft, even if the fire is burning, it can last for a while."

Especially for ground-level thunder or something, you have designed a gusset plate to hide the fuse at the fuse, and then seal a layer of wax, and the open flame roast cannot be burned, it must be in direct contact with the open flame. ”

Zhang Zhongqing patted his face: "Your method sounds okay, but you have to experiment to know how it works." ”

Speaking of this, Zhang Zhongqing remembered that he was now in the grassland, not in his well-equipped Thunderbolt Laboratory.

"Premature life!"

Zhang Zhongqing sighed, grabbed the reins of the horse, jumped off the horse, found a carriage loaded with cotton clothes, tied the horse to the back of the carriage, and jumped up to sleep.

On the grassland, where you have ideas but can't experiment, you can only sleep!

Keep going.........

When a small river three or four meters wide appeared in the telescope, Li Ke urged the war horse to take a few quick steps, caught up with the master and said, "Master, there is a river ahead, should we avoid it?" ”

It is common sense that the rivers on the grassland are generally inhabited by herders.

Li Xiaogong wanted to look through the telescope and shook his head: "This river is from west to east, just blocking our forward route, it's useless to go around, be ready to meet the enemy at any time." ”

After speaking, he raised a small yellow flag, and when he saw the soldiers of the flag, they all drew their weapons and passed the message backwards, which was a signal to prepare for war.

After only three miles of progress, I saw herds of horses drinking water by the river, and huge flocks of sheep.

It's okay to see a herd of horses on the grassland, horses are everywhere on the grassland, but the sheep are not good, and the sheep represent the herders who graze them nearby. Such a large flock of sheep is definitely not something that a few families can have, it should be a sheep of a large and medium-sized tribe.

The Western Turks are all soldiers, a large and medium-sized tribe, to say the least, there are thousands of people, which means that there are likely to be thousands of enemies nearby!

Sure enough, a row of war horses that were obviously not wild horses appeared from the front, followed by rows and rows of war horses.

Not long after entering the new land of the Western Turks, it was actually exposed!

"Prepare for battle!" Li Xiaogong shouted, and raised the yellow flag and the red flag at the same time.

The yellow flag is a signal to prepare for battle, the red flag is a signal to charge, and the appearance of red and yellow together means to act at the opportunity and decide when to fight.

It's a fool to take the initiative! Since the Western Turks are charging this way, it is better to wait for them to come to the front and consume some strength before meeting the enemy.

He tried his best to make a profit, and few old fritters on the battlefield didn't know.

"Damn, don't let people sleep."

Zhang Zhongqing, who had just fallen asleep, was woken up by the sound of drawing his blade, he was in the carriage, and stood up just in time to see the war horses running in the distance, as well as the Turks wielding scimitars on the war horses.

"Save the fuse on the nail cannon, grandma's, I'm worried that I won't have a chance to test it!"

The Turks of this tribe charged, and the rows were very neat, for Zhang Zhongqing, there was no formation more suitable for him to experiment!

Several members of the Thunderbolt Division jumped off their horses and lifted the nail cannon down from the carriage, the weight of the nail cannon is not large, two strong men can lift it, and its base has its own wheel, and there is also a turntable under the barrel, which is the most convenient to use!

The nail cannon is different from the artillery in that the gunpowder in it is already loaded, and when it is used, it is only necessary to pull out the plug in the front and insert the fuse in the back.

Completely fool-proof operation.

Seeing that Zhang Zhongqing was about to use a big killing weapon, Leng Feng hurriedly beckoned his legs to the back of the nail cannon, saying that he forgot to let Zhang Zhongqing calculate the fan-shaped attack range of the nail cannon!

After inserting the fuse, Zhang Zhongqing blew the fire fold and quietly waited for the Turks to approach.

100 steps, 80 steps, 50 steps!

Zhang Zhongqing lit the fuse.

Bang!

Smoke from the burning of gunpowder rose and countless triangular pyramid-shaped nails were sprayed out.
