A Mouthful of Sky-high Fried Rice, Lao Tang Apprenticed on the Spot

Ou Yezi was very confident about his prowess, but he found that Li Yi was not surprised when he saw him.

It wasn't until Li Yi casually drew a sketch of a hand blower that he knew why.

According to the sketch, he produced the required parts, and then Li Yi assembled it into a hand blower. He couldn't wait to install it on the stove and started testing it.

As a result, he was pleasantly surprised by the results of the test. The hand-cranked blower was countless times more convenient than the blower, and the effect was also better. The air supply was uniform and the wind intensity was much higher than that of the blower.

Moreover, it is best for two people to use the blower together, but only one person can use the hand blower, which more than doubles the efficiency.

After seeing the effect of the hand blower, Ou Yezi was shocked. He felt that the treasure he regarded as a treasure was instantly reduced and turned into a broken skin.

Li Yi didn't care about this, and even took the initiative to give the hand blower method to Ou Yezi, treating it as a disciple of Shuxiu.

After asking the retinue to take the message home, Li Yi stayed with Ou Yezi and learned the art of iron-making and sword-making from Ou Yezi.

After accepting the hand blower, Ou Yezi officially accepted Li Yi as his disciple and taught him all he had learned throughout his life.

After studying, Li Yi realized that Ou Yezi's method of making iron had actually already taken its prototype form.

The iron he refined is called refined iron. It actually uses repeated heating, folding and forging to make the iron structure denser, the composition more uniform, and the impurities gradually reduced, thereby improving the quality of the iron.

This process has a name in later generations, it is called steel made from hundreds of times.

Although to modern eyes, this approach may be a bit simple and clumsy.

But this was during the Warring States Period, when most metalware was still bronze.

Compared with bronze, the Baili Steel Sword made by Ou Yezi can indeed be called a magic weapon.

This folding and forging method has been passed down for more than two thousand years. Until the end of the Qing Dynasty, most blacksmiths still used this method to refine iron.

It took Li Yi three years to master what Ou Yezi had learned throughout his life.

In the past three years, the eyebrow ruler that has gradually grown up has also verified Li Yi's words.

He could not speak until he was three years old, and his reactions were slow and he looked very stupid.

Ou Yezi understood that what Li Yi said was true and realized that there was little hope of revenge for Gan Jiang, so he stopped mentioning it.

During the three years of teaching Li Yi, he also learned a lot from Li Yi.

He decided to concentrate on studying alloy technology and forge the stainless steel Li Yi mentioned as soon as possible.

Li Yi said goodbye and returned home.

The contradiction between Zhao and Qin is becoming increasingly prominent. The Battle of Changping is imminent, and everyone in the country is preparing for war.

The Xu family was also working day and night to manufacture ordnance for Zhao Jun.

It is precisely because of this that a large amount of materials have been allocated to the Xu family for management and use.

Taking advantage of this resource advantage, Li Yi began to try to smelt high-carbon steel.

During this period, Utz steel was already produced in India.

Utz steel is the predecessor of modern alloy steel. Powder metallurgy technology was already used more than 2,000 years ago.

It was through studying Utz steel that Faraday discovered that adding different trace elements to steel can significantly change the properties of steel, thus laying the foundation for the industrial production of alloy steel.

Faraday is also known as the father of modern alloy steel.

Li Yi asked Ou Yezi about wootz steel. Hundreds of years later, as the Silk Road was opened, wootz steel was brought to the country by Persian merchants and was nicknamed Bintie.

Iron was the best material for making swords during this period. The Damascus swords produced by Persian craftsmen were made of iron.

Li Yi believes that if he wants to leave this mysterious space, he must forge a better magic sword than Ou Yezi.

So he had to make wootz steel.

Wutz steel is high-carbon steel smelted in a crucible. Li Yi only remembered that its raw materials are high-purity iron ore, hemp chestnut charcoal, bamboo charcoal and the leaves of two so-called holy trees.

During smelting, it is burned and heated in a ceramic furnace to burn all the raw materials to form a ball of metal, which is then repeatedly melted and cooled, and finally made into high-purity wootz steel.

But apart from this information, Li Yi knew nothing about the smelting process.

Therefore, he could only use the stupidest and most useful exhaustive method to conduct experiments.

However, midway through his experiment, the Battle of Changping began.

Xu Qing also has military status, so he naturally needs to go into battle with the army.

However, Xu Qing's father asked him to stay at home and guard him while he wore armor and went into battle to defend the country from enemies.

Li Yi knew the outcome of this war. The Zhao army would be defeated because of Zhao Kuo, who was talking about war on paper. In the end, all 400,000 Zhao soldiers surrendered and were all trapped and killed by Qin Guo Baiqi.

He found Xu's father and reminded him tactfully, but Xu's father disagreed and thought that what he said was simply a fantasy.

There is a veteran general in Zhao State, Lian Po, who has defeated the Qin army several times. Is there any reason for An's disastrous defeat?

Seeing that he didn't believe it, Li Yi had no choice but to persuade him and could only watch him go to the battlefield.

The wheel of history will not change because of the obstruction of the mantis arm.

In the end, Xu's father died in the battle, and the 400,000 surrendered soldiers of Zhao were slaughtered by Qin general Bai Qi, leaving only 240 young Zhao soldiers who were released to Zhao.

For a time, in the Zhao Kingdom, the sons cried for their fathers, the fathers cried for their sons, the brothers cried for their younger brothers, the younger brothers cried for their elder brothers, the ancestors cried for their grandchildren, and the wives cried for their husbands. The streets and markets were filled with howls of pain.

Xu Qing's grandfather, Xu Du, was heartbroken and fell seriously ill because the white-haired man gave away the black-haired man.

Although Li Yi had predicted such a result, he could not change it.

He could only spend time in the weapons workshop, concentrating on refining iron, hoping to return to reality as soon as possible.

Because there were too many differences over the ceded land, King Zhao broke the contract and instead prepared for war. As a supervisory weapon, the Xu family was under great pressure.

Xu Du, who was originally in poor health, suddenly contracted a windstorm and died. The pressure of weapons production suddenly fell on Xu Qing.

Therefore, Li Yi could only shoulder the heavy burden, set up an assembly line, and urged the craftsmen to work hard to make weapons.

Perhaps because of the timely supply of ordnance, the Qin army failed to attack Handan repeatedly. In the end, the King of Qin killed Bai Qi in anger.

Later, Lord Pingyuan relied on diplomacy to invite the Wei and Chu coalition forces, and jointly defeated the Qin army.

At this time, Li Yi finally had a chance to breathe and focused most of his energy on the manufacture of iron.

Finally, after spending a total of ten years, he finally refined the iron and forged his first sword.

This is a standard eight-sided sword, the sword is three feet three inches long, the blade is two feet three inches long, and the hilt is about one foot long.

The eight-sided sword is the standard for bronze swords, because the texture of bronze is hard and brittle, which limits the length of the sword.

Therefore, when casting a bronze sword, the sword body will be widened and narrowed in the upper half. During casting, bronze with different tin contents will be used on the spine and blade to ensure its hardness and avoid breakage.

Li Yi's eight-sided sword forged from iron is much stronger and tougher than bronze, so it can have a blade length of two feet and three inches.

Moreover, the blade forged from iron is so sharp that it can break hair with ease.

Coupled with the exclusive oil quenching and tempering techniques learned from Ou Yezi, this sword is also unique in the world in terms of toughness. It can instantly return to straightness when bent at 90 degrees, and the quality is excellent.

No matter from any point of view, this eight-sided iron sword is better than the magic weapon Ou Yezi forged before.

However, what puzzled Li Yi was that after forging the sword, he did not return to reality.
