As the general in charge of Shanggongfang, before Gongshuqiu came back, he was the head of Shanggongfang. Xiangli Ao naturally knew the ambitions in Ying Zheng's heart.

He wanted to replace bronze with iron cavalry and enter the Iron Age.

The bronze technology of the Great Qin Empire was very advanced. When Xiangli Ao first entered Shanggongfang, he was amazed at the bronze technology of the Great Qin Empire.

However, Xiangli Ao knew very well that bronze technology had reached its ultimate in Daqin. Even if the craftsmen in Shanggongfang were so powerful, they would not be able to continue to make breakthroughs.

Humans can only constantly dig, but cannot break through its limitations and derive another type of object.

Therefore, when he walked into Shanggongfang from Xiangli Ao, he knew that the future would be the Iron Age to replace the Bronze Age.

The Qin Empire must bear the pain caused by this change.

Subsequently, Emperor First Emperor shocked Xiangli Ao and also felt a little loyal to Emperor First Emperor.

There is a saying, but heroes have similar views.

At that moment, Xiangli Ao felt that Ying Zheng was his like-minded person.

Since Ying Zheng issued an edict, he must have heard that it was inevitable that the Iron Age would replace the Bronze Age, which made Xiangli Ao very excited.

However, in addition to being the mastermind of Shanggongfang, Xiangli Ao himself is also a master craftsman. As a skilled craftsman from Qin Mo, he naturally knew how difficult it was to achieve this step.

This not only requires time to accumulate experience, and to obtain data through experiments over and over again, but also requires huge amounts of money and food as resources. Only in this way can the Iron Age arrive.

Although the Qin Empire had the strong support of Ying Zheng and continued to flow in money and food, he knew in his heart how difficult the Qin Empire was in finance.

If it weren't for the land reform, Wang Jian personally took action to kill all directions, and the Qin court today would soon be unable to continue to operate.

...

"Your Majesty, there have always been iron smelting on the Central Plains before. Even though His Majesty put forward many suggestions, it is extremely feasible, but those are all a theory and require experiments and verifications again and again."

"Since Shanggongfang developed a hydraulic blast furnace based on what His Majesty, Bailian Steel has just begun to be forged continuously, but Daqin has a huge demand for Bailian Steel."

"This also leads to the Qin Empire's need to make iron smelting technology advance by leaps and bounds, at least further than now. Only in this way can we ensure that the needs of the Qin Empire are met."

Xiangli Ao looked solemn. As a general of Shanggongfang, he naturally knew what life the craftsmen in Shanggongfang and the craftsmen in Shaofu had lived these days.

Some people even slept in workshops.

"Block iron smelting is iron that contains more inclusions. This iron is a sponge-like solid with more impurities, low carbon content, soft texture, and can only be forged and cannot be cast."

"Iron tools made by heating and forging, extruding inclusions and improving mechanical properties are called block iron smelting forgings. If during repeated heating, block iron smelting comes into contact with carbon fire, carbon seeps in and becomes hardened, it becomes block carburized steel."

At this moment, Xiangli Ao looked at Ying Zheng with a solemn tone and said, "Your Majesty, this is the result of Shanggongfang and Shaofu craftsmen over the past few days."

"However, I still don't understand the ideas provided by Your Majesty. The strength of the carburized steel is still insufficient..."

Upon hearing this, Ying Zheng's expression moved slightly. He knew in his heart that the steel frying method and the steel filling method he proposed were too advanced compared to this era.

This is the Qin Empire, and the emergence of steel speculation and steel filling methods are already in the late stage of feudal society, and are close to the Ming and Qing dynasties.

Moreover, in order to annex the world and maintain its advantages over weapons, the Qin Empire has never studied iron smelting technology, but has been constantly strengthening the evolution of bronze technology.

Although bronze technology was studied almost like black technology, this also led to the Qin Empire being at the lowest level in the seven countries in iron smelting technology.

As an emperor, Ying Zheng had a little understanding of it. He knew that the iron smelting technology of the Qin Empire had always melted iron ore from a vertical furnace, and then directly cast it with ceramic mold after obtaining the iron.

The forged cast iron in this way is all white iron, brittle and hard, and easy to break. In order to make cast iron production tools, Daqin learned tough cast iron from South Korea.

In this life, due to its own intervention, the Qin Empire had large iron smelting furnaces and hydraulic blowers, which made the cast iron heat treatment technology of Daqin in iron smelting technology significantly improve.

Ying Zheng knew several steelmaking methods, but he knew that it was too advanced and could not be realized in a short period of time. Therefore, he had only one idea, that is, the Qin Empire conquered the pig iron steelmaking method in the shortest time.

Moreover, Shanggongfang has mastered the technology of block iron smelting and block carburizing steel. If you want to overcome it, there is a great opportunity to develop the bio-iron steel smelting method.

As soon as he thought of this, Ying Zheng looked at Xiangli Ao and said, "When I was negligent at the beginning, everything needs to be done step by step. Let's stop the research on the steel frying method and the steel stuffing method."

"The craftsmen in Shanggongfang and Shaofu gathered together to study the birth iron steelmaking method in block iron smelting and block carburizing steel technology, and then let iron tools replace bronze tools."

"As for the steel frying method and the steel stuffing method, we can study it step by step in the future."

...........

"promise."

Nodding and agreeing, Xiangli Ao gave a breath in his heart. He knew that what Ying Zheng said was also a method, and it would be much easier to make breakthroughs based on block iron smelting and block carburizing steel technology.

As soon as the thought moved, she felt a tentative thought in her eyes: "Your Majesty, I don't know the method of making steel from pig iron..."

At this moment, Ying Zheng spoke and said, "I have a technique, pig iron steelmaking method, which mainly uses pig iron decarbonization. While heating repeatedly, blow air into decarbonization to turn pig iron into steel. This technique is: blowing oxygen."

Upon hearing this, Xiangli Ao hurriedly bowed to Ying Zheng and said, "Thank you for your advice, I have recorded it!"

Xiangli Ao is a top craftsman of Qi Mo and is also leading the reform of iron smelting technology. Naturally, he knows every step of iron smelting technology.

He just tried it, but unexpectedly Ying Zheng really gave him the answer. Although he didn't know the truth or the false, he felt that it was very likely to succeed in his research on iron smelting technology over the past few days.

Because of this, Xiangli Ao looked at Ying Zheng with a hint of awe. His Majesty the First Emperor of the Great Qin not only had the appearance of returning to old age, but also had the ability to know it in life.

It is really the luck of the Qin Empire to have such an emperor, the luck of the people, and even the luck of this era.

With such an emperor, it is really clear that the heavens have eyes!

After hundreds of years of chaotic battles and countless people died, we finally welcomed a holy lord. On the Central Plains, there will be prosperity and prosperity.

At this moment, Xiangli Ao believed it very much.
