I have to say that Liu Asi's knowledge is still relatively broad, and he actually knows that gunpowder can be used for alchemy.

The appearance of gunpowder was indeed inadvertently invented by Taoist priests at the earliest.

As we all know, although the Chinese Taoist priests have a strong heart, they are really bold, and this is not acceptable.

In order to seek immortality and ascend to immortality, dare to do anything, the pill is mixed with mercury, sulfur, and all kinds of heavy metals that cost human life, and the refined pill not only dares to swallow it yourself, but also dares to give it to others, and even dares to give it to the emperor.

As far as Qin Shi Huang and as close as Li Shimin, they have all been plagued by the elixir of Taoist priests, if the two of them believe in science and do not take drugs, they can live at least one or two decades longer.

Gunpowder came out inadvertently in the process of Taoist alchemy.

There is a book "Taiping Guangji" that in the Sui Dynasty, a man named Du Zichun went to visit a Taoist priest who made alchemy, and heard a bang in the middle of the night, the alchemy furnace exploded, and the air exuded a strong smell of sulfur saltpeter, which is probably the earliest record of gunpowder.

Li Qinzai was convinced of Liu Asi's erudition, but it was out of place.

"Why did I let you take the top prize!" Li Qinzai said, "Gunpowder, what else can you do besides filling the three-eyed gun? Use it to explode the eggs!"

Liu Ah Si smiled: "Li Shuai is not strange, the villain was very smart when he followed Li Shuai, but after a long time with the miscellaneous people of the special operations team, it seems that he has not woken up......

Li Qinzai instructed his subordinates to bring a few pieces of oiled paper, and half a catty of gunpowder, and demonstrated in front of Liu Asi, using oiled paper to tightly seal the half-catty gunpowder layer by layer, and finally pulled out a long lead from it.

An improvised explosives pack is complete.

"The fuse is a little longer, and the future generations are a little farther away when it is ignited, the power of this thing ...... Well, you've seen landmines anyway, right?" Li Qinzai said.

Liu Asi's face changed, and he stammered when he spoke: "Li, Li Shuai, this thing...... What are you doing it for?"

Li Qinzai took a moment to point to the top of the canyon at the end of the mountain road, and said, "You take the special operations team to make a few more explosive packs according to the method I just made and bury them in the canyon."

"After the ambush, if the enemy escapes from here, you are our last sniper position, seeing the moment for the enemy to pass through and blowing up the canyon, do you understand?"

Liu Asi nodded: "Understood."

Li Qinzai smiled and said, "Go ahead, if you have made meritorious contributions in this battle, my brother will find you a sister-in-law when you go back."

Liu Asi thanked him excitedly, rubbed his hands, picked up the freshly baked explosives bag with a solemn expression, and left tremblingly as if he were holding the ancestral tablet.

The scout's information was accurate, and two hours later, a troop of 3,000 men and horses came on foot and made their way through the mountain path.

Li Qinzai looked coldly at the enemy troops passing under the mountain, and did not give any orders.

He knew that this was the vanguard of the enemy, and this group of men and horses had to be let go, otherwise they would be startled.

After the enemy's advance passed, and after waiting for another hour of incense, the Chinese army finally came.

Li Qinzai's eyes lit up, he held his breath and stared at the enemy soldiers walking on the mountain road, his expression was slightly nervous, and then he looked at Wang Fangyi beside him silently.

Professional things are left to professional people to do, and Li Qinzai has delegated power to Wang Fangyi, and he decides when to launch the ups and downs.

In the quiet mountain forest, I don't know when a layer of surging fog was shrouded, and the murderous machine lurked in the mist.

Wang Fangyi stared at the enemy troops on the mountain road, and after the Chinese army had exceeded thousands of people, finally, Wang Fangyi personally lit a ringing arrow.

There was a sudden explosion, and the valley echoed with the aftermath. At the same time, countless Tang soldiers stood out from the dense forest, and the three-eyed guns simultaneously opened fire on the enemy troops on the mountain road.

At the first volley, thousands of enemy troops fell with screams.

Caught off guard, the enemy was stunned in an instant, and the main general had no time to react, let alone ordinary soldiers, the entire army and horses fell into a panic, the general did not know the soldiers, the soldiers did not know the generals, and after several rounds of volleys, the enemy's formation was disrupted.

When the Tang soldiers ruthlessly slaughtered the enemy, Wang Fangyi pointed to the rear of the enemy and shouted, "Liu Renyuan, lead 3,000 soldiers

The horse made a detour to the rear of the enemy and cut off his retreat!"

Liu Ren was willing to lead the army and hurried away.

Wang Fangyi said again: "Black teeth are common, and the dogs only care about their own fights, what about people?"

Deep in the dense forest, Black Tooth Changzhi excitedly rushed out.

Wang Fangyi glared at him and said, "You are the forward officer, what kind of excitement is there here, immediately lead the forward battalion to the front and cut off the enemy's front."

Hei Tooth Changzhi smiled, turned around and ran again.

Wang Fangyi breathed a sigh of relief at this time, smiled at Li Qinzai, and said, "Li Shuai, the front and back are blocked, most of the enemy's soldiers and horses have entered the Ghost Gate Pass, and the King of Hades can't be saved."

Li Qinzai nodded: "I don't have to worry about handing over the wartime command to you."

Wang Fangyi was quite touched by Li Qinzai's trust, and sighed: "It would be great if the last general could follow Li Shuai for the rest of his life, and it is really a great joy in life to follow Li Shuai to fight."

Li Qinzai glanced at him and said in a surging voice: "You just bully me and don't understand anything, and you don't dare to joke with the lives of soldiers, so I can only give you power, right?"

Wang Fangyi said with a smile: "Li Shuai said this, no matter who commands it, the imperial court can only recognize Li Shuai, I am just your lieutenant general."

On the mountain road, the enemy army has become more and more panicked, this army is a little strange, looking at their fighting quality, it is very different from the Goguryeo army that Li Qinzai encountered in the past, obviously much weaker, inexperienceless.

After observing for a long time, Li Qinzai finally came to a conclusion.

The seemingly mighty 30,000 enemy soldiers and horses should be a new army, or rather, it was formed by the Goguryeo people who temporarily pulled Zhuangding, and there was no time to practice and fight, so after encountering an ambush, the performance would be so unbearable.

In today's situation, Goguryeo is losing and retreating, losing cities and losing land one after another, the Tang army has taken the initiative, and the soldiers and horses of Goguryeo that can resist the Tang army are also constantly being consumed.

The regular army has become increasingly insufficient, and there will be more and more of this kind of makeshift patchwork of troops in the future.

The national situation has gone, and the sword soldiers are declining, which is so intuitive.

In today's ambush, Li Qinzai was completely relieved.

There is no suspense about belonging.

Seeing that the enemy's casualties were almost half, and they still couldn't organize an effective counterattack, and the officers and men of the Tang Army were simply slaughtering unilaterally, Li Qinzai showed a relaxed smile on his face.

At this moment, a scout, sweating profusely, walked through the dense forest and rushed to Li Qinzai's side.

"Li Shuai, Black Bone City is in an emergency!"

Li Qinzai was stunned for a moment and looked at the scout: "Say."

"Three days ago, Yinggong, the general manager of the Liaodong Road march, led the king's division to open the Black Bone City, because of the wind and sand, the horse's eyes were lost, the war horse went crazy, Yinggong was thrown off the horse, his right leg was broken, bleeding nonstop, and the person was also unconscious."
