The formula of gunpowder did not have any bird use, and Yan Liqiang was not disappointed, but quickly accepted this reality, on the contrary, for some reason, Yan Liqiang still had a sense of relief in his heart, and he saw his future path more clearly.

A world that can never have thermal weapons, perhaps, is not a bad thing, when going down the mountain, Yan Liqiang secretly thought in his heart, this world has no thermal weapons, and at the same time, this world lacks the necessary conditions for the production and use of electricity, which means that this world will not have atomic bombs in the future, nuclear weapons, there are so many strange things that can make human beings easily destroy themselves, of course, there will not be so many pollution, diseases......

When it becomes more difficult to kill a person, it means that the possibility of human beings destroying themselves is decreasing, and the cost of killing each other is increasing, which is not bad, is it?

From the perspective of the development of productive forces, the peak of the development of the world's future productive forces is equivalent to the first industrial revolution on the earth, and the use of steam and the invention of the steam engine may be the most powerful force that human beings in this world can conquer the natural world.

And the principle of the steam engine is actually not complicated.

When Yan Liqiang thought of the steam engine, a 3D animation of the structural principle of the steam engine that he had seen on the Internet in his previous life naturally appeared in his mind.

Yan Liqiang, who was walking on the mountain road, shook his head.

He didn't come to this world to be a craftsman, in fact, the status of craftsmen in this world is not high, even if he takes out the design drawings of the steam engine now, the drawings don't mean much to him, and they can't change anything, there is no invention patent in this world, if the steam engine is really useful, others can buy it and imitate it, and it has nothing to do with him, maybe the steam engine drawings brought him less than one-tenth of the wealth that the Lu family rewarded him.

One hundred taels of gold is a huge wealth for any craftsman, at least Yan Liqiang has never heard of a craftsman who can be rewarded with a few hundred taels of gold after inventing something, and a few hundred taels of gold cannot solve the practical problems he has to face for Yan Liqiang now, let alone let the Hong family turn enemies into friends with him.

Therefore, in this kind of world that is forever destined to be ruled by cold weapons, if you want to mix well in this world, not be mermaids, and have the ability to protect yourself, the most important point is to cultivate, and cultivation is the king!

When he went down to the foot of the mountain, it happened that Yan Liqiang met the team of sergeants in the morning, and it seemed that the team of sergeants was also preparing to go back to the canteen to eat.

"Hahaha, big brothers, it's a coincidence......" Yan Liqiang smiled and took the initiative to say hello to the sergeant.

"Ah, how is Yan Shao practicing?"

Yan Liqiang deliberately rubbed his shoulders with a sad face, "Brother Zhou's horned python bow is too strong, I only pulled it a few times and couldn't pull it, it looks like I have to take my time......"

"Hahaha, this is a five-stone strong bow, Yan Shao can pull it out now, it's already amazing......" The captain of the sergeant who spoke glanced enviously at the horned python bow that Yan Liqiang was carrying, "I believe that Yan Shao will be able to fully exert the power of this horned python bow in the future, brothers, don't you say?"

"Yes!" a bunch of sergeants laughed.

"Thank you big brother Jiyan, go, go, go, let's go to dinner, eat......"

"Hahaha......"

......

After lunch, Yan Liqiang continued to return to the mountain.

In order to verify the formula of gunpowder, he had wasted a morning, and now that what should be proved has been proven, and what should be clear has been clear, Yan Liqiang naturally returned to the track of cultivation, and cultivated even harder.

Less nonsense......

Yan Liqiang directly gave himself a review of the Yi Jin Washing Meridian under the scorching sun to replenish his body.

After practicing the exercises, in less than two hours, Yan Liqiang felt that his whole body was washed by the aura and energy of heaven and earth again, after the exercises, the whole person was refreshed and refreshed, and the spirit was a hundred times, what is even more strange is that even under the scorching sun, after the practice, in addition to sweating, Yan Liqiang did not feel hot, but had a comfortable feeling of wind in the armpits.

It's time for the show to be truly technical...... Cough...... Cough......

Yan Liqiang, who had warmed up with the Yi Jin Washing Pulp Sutra, then opened the bow sac, took out the horned python bow, and began to practice archery.

The bow and arrow, in the era of cold weapons, was definitely the most powerful weapon, and there was no one.

Once on the earth, the Mongols, with a population of two or three million and a total of only a few hundred thousand soldiers, swept across the entire Eurasian continent with iron hooves under their crotch and bows and arrows in their hands, destroyed countless countries, and established the Dayuan Empire, which had the most extensive territory in human history.

As long as you have a strength and can shoot arrows, a reckless man can easily kill people dozens of meters away, and it is impossible to guard against it, this is the power of the bow and arrow, which is also incomparable to any other weapon.

In the Silver Continent, archery is called kyudo, and after advanced samurai, archery is the head of the six arts. And because the cultivation method of kyudo is different from ordinary martial arts, many people even juxtapose kyudo cultivation with martial arts practice, and some extremes even think that the importance of kyudo is far above martial arts, which shows the importance of kyudo.

When the unknown danger is rapidly approaching you, and someone wants to kill you, you have two choices in front of you, one is to find a master to practice martial arts, to fitness, to learn sanda martial arts, and the second choice is to pick up the rifle or pistol in front of you and learn to shoot, which one will you choose?

Yan Liqiang will not hesitate to choose the second one, because the second one has the fastest effect and the most powerful, so this is why he chose to start learning archery today.

Archery is a method that can transform a person's strength into lethality in the most efficient way, and at this point, no martial arts can surpass it.

Yan Liqiang has nothing else now, but he has strength.

To practice archery in the mountains and forests, you don't need any targets, you just need to find a big tree at random.

Yan Liqiang's target is a big tree thirty meters away from him, the trunk of that big tree is as thick as a person hugging him, it looks just a little thicker than a human body, and behind the big tree is a dirt slope and grass, and the arrow will not hurt people after shooting, let alone running too far to pick it up, which is the most suitable for practicing archery.

The first arrow, Yan Liqiang pulled a full bow, he aimed at the tree trunk in the distance, as soon as his hand was loosened, the bowstring of the horned python bow shook, and only a slight "boom" was heard in his ears, and the arrow had already flown out, as fast as lightning, and disappeared in ......

The arrow that shot out really disappeared, because Yan Liqiang's eyesight couldn't catch the trace of the first arrow shot out at all, he didn't even know where the arrow had shot, he only felt that it was missed, because after he shot it, the trunk of the tree that was the target was still empty, and there was nothing.

The first arrow missed, and the horned python bow was drawn too full, and the power was too great, and at such a close distance, there was no need to fill the bow at all.

When shooting the second arrow, Yan Liqiang learned the experience of the first arrow, only pulled the bow to about one-third of the position, and shot another arrow, after the arrow of the second arrow was shot, it was still difficult to catch with the naked eye, and the speed was still fast, but Yan Liqiang still saw that this arrow flew from the left side of the trunk of the big tree and did not enter the grass pile on the dirt slope behind it.

Yan Liqiang adjusted again, and the third arrow shot out......

This arrow is somewhat to the right.

The fourth arrow, then to the left......

The fifth arrow, grazed the trunk of the tree......

For Yan Liqiang, archery is completely a strange enjoyment, when shooting each arrow, no matter whether the arrow hits the target or not, Yan Liqiang's heart, there will be a warm and quiet sense of joy, the arrows flying out of his hand, in Yan Liqiang's eyes, like he opened the cage and released a small bird into the sky, and like a small fish and loach that he bought from the fishing market and put into the rivers and lakes, as long as he can watch these things return to freedom from his own hands, this in itself is already a kind of enjoyment and satisfaction, like a spiritual massage。

The lifeless horned python bow and cold arrows, in Yan Liqiang's eyes, seemed to slowly turn into life with warm body temperature from the moment he began to pick up their first arrow, which naturally made him feel close.

......

The eighth arrow was shot, and finally, with a "grab" sound, the arrow of the arrow finally nailed to the trunk of the tree like a nail, and the whole arrow was submerged into the trunk, only the shaft of the arrow was still trembling after hitting the target......

The ninth arrow, which hits the target again, and the tenth arrow, still hits the target......

This first pot of arrows, a full thirty-six, except for the first seven arrows did not hit the target, the back twenty-nine arrows, all hit the trunk of the tree, firmly nailed to the trunk.

This arrow didn't seem to be too difficult, Yan Liqiang muttered in his heart, walked over, and collected all the arrows he shot.

The arrows that hit the trunk of the tree had to be matched with a knife to dig out the arrows, and the seven arrows that shot to the back slope were found six, and the first arrow shot by Yan Liqiang was too strong, and the whole arrow was completely submerged in the dirt slope, only a little feather at the tail of the arrow was still exposed, and when Yan Liqiang wanted to pull it out, he found that the shaft of the whole arrow had already been broken......

......

After all, the strong bow of five stones is a strong bow of five stones, after shooting thirty-six arrows, even if the bow is not full, Yan Liqiang still feels that his arm is a little sore, and his strength consumption is very large, he ran to the edge of the mountain spring next to him, drank a little clear and sweet mountain spring, and rested for a while before continuing to practice archery......

In the second exercise, all 35 arrows were shot at the trunk of a tree 30 meters away, and none of the arrows missed the target......

In the third exercise, all 35 arrows were shot at the trunk of the tree in one go, and none of the arrows missed the target and shot crookedly......
