Simply hanging two wheels, let the three-stone bow exert the power of four stones, with the polished three-edged arrow, within a hundred steps through four layers of leather armor, even the most powerful Mingguang armor was shot through.

Is it powerful? No, Li Chengqian said that this is not the most powerful, and it would be better if these two wheels were mounted on a strong crossbow.

Li Er, Li Jing, Qin Qiong and the others stared blankly at the three-stone bow poked next to the shelf, no one spoke for a long time, no matter what, they couldn't understand why adding two wheels and lengthening the bowstring would increase the power to such an extent.

The power required has not changed, it is still the power of three stones, that is to say, the standard two-stone bow has been transformed to exert a power close to three stones.

In this way, the shooting distance of the bow can be increased, and the original 100 steps to open the bow has become 130 steps, and this extra 30 steps can completely increase the round of shooting. If you add a triangular arrow, a long distance, and a powerful destructive power, all this will become a nightmare for the enemy.

"Your Majesty, change your clothes!" Qin Qiong took a deep breath, suppressed the urge to go to the battlefield again, and said to Li Er in a deep voice.

"Yes, Your Majesty, let's change your clothes." Cheng bit the gold thief looked at the transformed strong bow with shimmering eyes, and couldn't help but swallow it in his stomach.

"Liu Qing, how much time does it take to transform a bow?" Li Er waved his hand, stopped the others from talking, and asked Liu Min seriously.

"If the accessories are not bad, the tea time can be changed." Liu Min recalled for a moment and said an approximate time.

"Very good, very good." Li Er nodded with satisfaction, and sighed in his heart that the bastard boy in his house really spared no effort to trap the Japanese people.

Forcibly increase the military strength of the Tang Dynasty, and then sell the eliminated things to the Japanese people, and then use the money from the sale of weapons to build new equipment.

Glancing at Li Chengqian, who was squatting in the distance digging an ant's nest, Li Er wanted to open his head to see what was inside. To be able to come up with such a strange idea, this transaction is simply too cost-effective.

And the arms business is really profitable.

A bow is sold for 30 times, and the cost is only 7 or 8 times, so it is necessary to dry the wood in the shade and shape it, which is more troublesome.

Arrows are sold to a hundred, and this one is not cheap, and this is a consumable, so it can be said that how many are not enough.

The knife is sold for 500 guan each, and the cost seems to be only about 10 guan.

If this business can be done, it will not take too much, 10,000 knives, 30,000 bows, and a million arrows, and then you will make a fortune.

"Your Majesty, Your Majesty." Li Er, who was daydreaming, was woken up by the ministers in a row, blinked his eyes and asked, "What's wrong?" ”

"Your Majesty, do you want to change your clothes?" Cheng Yanjin looked at Lao Li with sensible eyes and asked.

"Change, it must be changed, and as soon as possible." The wealth is charming, Lao Li seems to see a mountain of gold in front of him, how can he disagree.

"Well, Father, I can't change it, at least not now." Li Chengqian, who was digging out the ant nest, heard Lao Li's excited voice and hurriedly stopped him.

"Why, why can't you change it?" Without waiting for Li Er to speak, Fairy Cheng glared at a pair of bull's eyes and roared.

"Without steel, we don't have enough production, and it's not just bows and crossbows that need to be replaced, so the gap will be even bigger." Returning the three-edged army in his hand to Wu Chen, Li Chengqian returned to Lao Li's side and said slowly.

The angry veterans fell silent almost instantly, all aware of this insurmountable obstacle.

Li Chengqian is right, the steel production is not enough, and wanting to change clothes is tantamount to a fool's dream.

"What did you just give you a guard? I look very familiar, take a look. Li Er's eyes were very poisonous, and after a while, he actually noticed the three-edged army.

"Triangular Sword, a special kind of knife." Li Chengqian beckoned to Wu Chen, took the three-edged military sword that had just been wiped clean from his hand, and handed it to Lin Songhai, the guard beside Li Er, and couldn't help but sigh in his heart, Wu Chen was afraid that he would not be able to keep it.

"Triangular Army." Taking the slender hand over from Lin Songhai, the dark army slashed, and the corners of Li Er's eyes twitched fiercely.

The same shape as the triangular arrow, but much longer, according to the experience of the triangular arrow, this army is also a thing that stabs whoever dies.

"If there's anything good, take it out and see." After playing with the military in his hand for a while, Li Er handed it to Qin Qiong and the others, satisfying their curiosity and asking Li Chengqian.

As a result, more than a dozen knives were taken out of various positions on Wu Chen's body one by one.

A group of old killers, except for Li Xiaogong, the rest of the people almost didn't stare out of their eyes, but they didn't expect that there would be so many knives on the body of a simple person.

"Prince, Prince, you say...... Do you say that you can do something serious in a day, what are you doing with so many knives? Fiddling with more than ten sabers of various types in front of him one by one, Li Er said to Li Chengqian helplessly.

"Father, hobbies, look, how beautiful they are." Li Chengqian said with a bitter face.

"Hmm. I think it's good, too. Li Er nodded.

Li Chengqian didn't have any intention of betraying people when he built these sabers, so Li Er knew that these knives existed, but he never had the opportunity to see them.

Now I finally have the opportunity to see it, and I can't put it down more or less, especially the huge back teeth and deep blood grooves of the tiger tooth saber, which are sharp weapons for killing people at a glance.

More than 1,300 years have passed, but the temptation of the saber to the soldiers has never changed.

Li Er is now the emperor, but he is still a soldier in his bones, so Li Chengqian, who is full of bitterness, can only go back and rebuild.

An experiment finally turned into a saber carve-up conference, and apart from Li Chengqian, everyone got more or less something they liked.

Such a result was unexpected by Li Chengqian, so he decided to find it back in the devil, Huiri's unlucky guy has applied to see him three times in a row, and now it seems that he should be given a chance.

Uchito, the deputy envoy of the Wakoku Mission, was a pharmacist by profession, and he was also a retainer of Soga Ezo. In the case of Su I's Ezo power, Hui Ri's status naturally rose with the tide, and slowly this goods developed the habit of seeing everything in the Wa country, except for the clansmen of the Su I clan, Ya almost didn't put anyone in his eyes.

As a result, after arriving in Datang, Ya ran to Li Chengqian's heel and pretended to be, and took the initiative to send the big face to Li Chengqian's feet, and then got the ending that Wu Chen and Heizi were filled with the same as a special pot-bellied water toad.
