Sheepskin, chicken feathers, pigskin glue, fine wood, and soon, a new double-acting piston bellows was born.

This was the idea that Li Ling had when he went to the blacksmith shop to make stirrups, because it was not until he arrived at the blacksmith shop that Li Ling discovered the most fundamental factor of the backwardness of the current iron-smelting technology.

Li Ling had always thought that the improvement of iron-smelting technology could only start with two methods, the formula and the forging method, but when he got there, Li Ling found that there was actually another way to go, that is, to increase the temperature of the furnace and force out as many impurities as possible in the ironmaking stage.

The most direct way to increase the temperature of the furnace is a blower, Qin does have a blower equipment, but it is a kind of thing called a blower, in fact, the image is basically equivalent to a manual oversized plastic bag, sucking air, and then blowing out.

It seems to have some effect, but the effect is extremely limited and does not provide continuous wind power at all, which is why the furnace temperature cannot reach an optimal temperature.

The simple bellows, an old object that has long been obsolete in the eyes of later generations, has become an epoch-making invention here.

"I've given you the bellows now, in addition to increasing the number of forgings, you can also try adding something else to the molten iron, maybe it will have unexpected effects, I hope you don't let me down."

Giving Hu Yan the greatest convenience, let him concentrate on researching and improving the iron-smelting technology, and as for forging horse harnesses, it was handed over to his apprentice, Li Ling looked at the burning red furnace, and his heart was full of enthusiasm.

I thought that I might be dormant for a while, and I was planning to enjoy life, but I didn't expect to have so many gains.

"Looks like I need to beg someone."

After having the perfect cavalry equipment, Li Ling really couldn't hold back the excitement in his heart, and he couldn't wait to equip the troops with these things in batches immediately, but now he ......

Going straight to the Wenxin Marquis Mansion, Li Ling went to ask for someone for the first time, and he was still asking for a person who already regarded himself as a threat - Lu Buwei.

After staying in Lü Buwei's mansion for less than half an hour, Li Ling left satisfied, and even Lü Buwei personally sent Li Ling out.

In fact, Li Ling didn't pay anything, and he didn't ask for much, that is, he wanted to form a cavalry of 1,000 people, as for the reason, he was too bored to be idle now, and he really had nothing to do.

Forming a cavalry force of 1,000 people and garrisoning outside the Xianyang City Gate, it did not pose any threat to Lü Buwei, and at the same time, Li Ling even took the initiative to indicate that he did not plan to return to his 10,000 foot soldiers before.

In Lu Buwei's opinion, this kind of behavior is to take the initiative to show weakness and curry favor with himself, which naturally makes him very happy, he not only promised Li Ling, but even promised to package all the equipment and materials of this cavalry, but Li Ling chose to refuse, but the words of refusal were very beautiful, it seemed that Li Ling wanted to follow Lu Buwei very much, but he didn't want to add even a little burden to Lu Buwei.

"Uncle, uncle, have you heard, Wu Sui has been defeated, and we have walked out of Hangu Pass again!"

"Oh, I heard."

Li Ling, who was recruiting troops, reacted very coldly to Meng Tian's words, this was the third day that he had received Lü Buwei's promise to form cavalry, but now his cavalry team had only recruited more than 300 people.

This is not that the Qin people are unwilling to join the army, but at the same time, there are other generals who are also recruiting soldiers, and other troops are recruiting soldiers to go directly to Wusui, and they have the opportunity to make military achievements and become officials.

But Li Ling's cavalry, I don't know who released the rumors, saying that it was just because Taifu was bored and wanted to form a team of people for him to have fun......

"It's Grandpa Wang Su's Wusui City that broke first!"

"Oh, got it."

"I heard the news from my father that the troops led by Grandpa Wang Su are your uncle's soldiers and horses."

"Hmm."

"Hmph, if you don't want to deal with me, I'll go play by myself!"

"Oh."

"Then I'll go and play with Mo You."

"Hmm."

Meng Tian bounced away, Li Ling drooped his face, it was not interesting for him to stay here, it was still interesting to play with Mo You.

Li Ling was distressed, he knew that the fundamental reason why he couldn't fight for the source of troops was the rumor, but he couldn't refute it, because the so-called rumor was the reason he said when he went to find Lu Buwei.

"You stay here, I'll go back to the camp first."

Handing over the scene to a subordinate, Li Ling went back to the camp directly, and it was really aggrieved to stay here.

......

"You may have also heard that this cavalry team is what I am bored to do, you may not have the opportunity to go to the battlefield, let alone make war exploits, why do you choose to follow me?"

Back in the camp, looking at the more than 300 people in this area, Li Ling asked directly.

However, no one answered out loud.

"You, tell me, why?"

"My brother died on the way from Gongcheng to Gaocheng."

"Aha? What are you doing, you want to seek revenge on me? Or are you afraid of death and don't want to go to war? ”

I ordered a random person, but I didn't expect to find that this person still has some relationship with himself, but this origin is not a good thing.

"I heard a man who came back from Gaocheng talk about the general, so I don't believe the general is just for fun!"

The man raised his head suddenly, staring at Li Ling directly, he was waiting, although he was just an ordinary person, he was not afraid, he was expecting.

"What about you?"

However, Li Ling didn't give the man any response, and went directly to a farther place, found a guy who looked submissive, and asked again.

"My father lost a leg in Gaocheng, and he asked me to come."

Another similar answer!

Li Ling then asked several more people, and the answers they got were almost all similar, all of them had a certain relationship with himself.

"You are all here because of me Li Ling! Right! ”

"Yes!"

"Well, whether I came here because you trusted me or because my family asked me, I want to tell you that your future, on the battlefield, your stage is the whole world!"

No wonder Lü Buwei would have agreed so happily after hearing his reasons, if it weren't for the fact that these people were relatives and friends of his subordinates, I am afraid that he would not even want to recruit any soldiers.

"If you have horses, weapons and armor, you can bring them when you go home, and if you don't have them, go to my side to make a registration, and I will make arrangements."

As soon as Li Ling left, the quartermaster immediately took action to make final preparations for the official start of the training.
