"Your lord, the boy did help his father, but even if there is no boy, there will be others who will improve." Mrs. Xu said.

It is not that there is no blast furnace in Zhao State, but it is just a copper smelter, not an iron smelter. However, in Mrs. Xu's opinion, everything is almost the same, as long as some simple adjustments are made, the sealing and thermal insulation performance is improved, and the blast equipment is changed to make the blast furnace reach a higher temperature, everything is a matter of course, without him there will be others.

As everyone knows, Zhao Guo has been trapped for four whole years at this step, without him...... Maybe I'll be trapped for another four years.

There are some things, in the hands of geniuses, which can be solved quickly, but in the hands of ordinary people...... Maybe it won't be solved in ten or twenty years...... The reality is so cruel.

"I remember that your father has a place in Handan Academy, why didn't he enter Handan Academy?" Zhao Kuo asked.

It was the time for classes at the academy, but Mrs. Xu was in the workshop, obviously not going to Handan College to study.

With a talent like Mrs. Xu, it would be a pity if she didn't enter the academy for systematic study.

"Your Majesty, the kid is studying at Handan Academy now. It's just that I heard that the furnace was opened today, so I asked for leave......" Mrs. Xu scratched her head and said with some embarrassment.

"Study hard, not only to learn the basics well, but also to maintain your spirituality, remember?" Zhao Kuo admonished.

"Boy, remember." Mrs. Xu nodded solemnly, as well-behaved as a child. Well, he's still a kid now, but with his rugged appearance, it's a little funny.

Liu Ping, who didn't know when he disappeared, returned to Zhao Kuo's side, lowered his head and whispered a few words.

"The order, Mrs. Xu has made meritorious contributions to improving the blast furnace, and she will be named Xiaqing, and the rest of the people will still be rewarded." Zhao Kuo heard the news that Liu Ping had just gathered, and opened his mouth to announce.

According to the workers in the workshop, Mrs. Xu did often go in and out of the workshop, and put forward constructive suggestions, and the success of the blast furnace construction is inseparable from Mrs. Xu's help.

Although Zhao Kuo had heard of Mrs. Xu's name in history, after all, it was really hard to forget this name after seeing it once...... But let's make sure.

This is also what the reward must do, and it is impossible to directly award the reward without even confirming it.

"The king, the minister......" Xu Da took a step forward.

"You're still the same." Zhao Kuo waved his hand to interrupt it, and the dignified Zhao Kingdom was not short of this reward. Besides, a false name and some land in exchange for the loyalty of father and son, it is not too cost-effective.

"Thank you, Your Majesty." Xu Da was excited. He originally thought that after this matter was said, his reward would be gone, but he didn't expect that King Zhao not only rewarded his son, but even his reward was not withdrawn.

"These are all things that Qing deserves." Zhao Kuo waved his hand and said.

"The boy has something he wants to dedicate to the king." Xu Da pondered for a while, and finally made up his mind and said solemnly.

"Oh? I don't know what it is? Zhao Kuo asked with a smile. Xu Da didn't speak, but looked around, signaling that there were many people here.

"Okay, let's disperse, what to do and what to do." Zhao Kuo waved his hand and said,

"In the next period of time, the workshop will focus on building blast furnaces, and how many can be built."

"No." After the people had bowed, they dispersed in all directions. Jurisdiction

"Let's go outside and talk." Zhao Kuo turned around and walked outside, and Mrs. Xu followed closely behind. When he got outside, Zhao Kuo stopped and motioned for Mrs. Xu to speak.

"Your Majesty, what the kid wants to offer to the King is the Spiritual Injection Technique, a technology that can inject aura into the weapon, conceive the weapon, and improve the performance of the weapon." Mrs. Xu whispered.

"Soul technology? Is there a physical object? Zhao Kuo's eyes lit up, if what Mrs. Xu said was true, the importance of this technology would go beyond the blast furnace.

Due to the existence of aura in this world, the mountains and rivers are being subtly changed all the time, and the difficulty of metal smelting is higher than in history, and the quality of the weapons created is also higher than in history.

However, this increase is not large, and it is not worth mentioning at all compared to the improvement of living creatures such as humans and beasts.

This has led to a phenomenon that weapons, armor and other equipment are far inferior to people in terms of improving their strength. Governing a legion dressed in cloth against a well-equipped legion, even if it will be defeated, it will have a certain ability to resist.

But a group of miscellaneous soldiers, not to mention encountering the super elite and the army soul legion, is encountering the elite, and it is also a one-sided slaughter.

Of course, no country's super-elite fights in cloth...... Strong legions are bound to be equipped with the best equipment.

With the Soul Infusing technique, the performance of the weapon will be greatly improved, and it will become as important as a person.

What's more, in the future, Zhao Guo will face the six countries, even if the troops are the same, it is very likely to play a crushing record, or even sweep!

"Your Majesty, please look." Mrs. Xu took off the small hammer on her waist and handed it to Zhao Kuo. From the outside, there is no difference between the small hammer and the ordinary hammer, but after falling into his hand, Zhao Kuo obviously felt that something was different, this hammer was more textured, and the internal qi was transmitted more smoothly inside.

Zhi Zhao Kuo waved the small hammer and smashed it towards the bluestone on the side, only to hear a 'boom', the bluestone was torn apart, and the small hammer was intact.

"However, this technology has certain limitations, and it can only be used by craftsmen with internal qi, and ordinary craftsmen cannot inject spirit into equipment." Mrs. Xu said.

The biggest difference between the Soul Injection Technology and the Spirit Sealing Technology is that one is to inject Aura after it is built, and the other is to inject Aura during the creation process.

The advantage of sealing the spirit is that it is highly popular, and after the equipment is built, it can be sent directly to the soldiers to instill the aura, and the disadvantage is that it takes a long time, it may take a year, and the performance of the equipment can be improved to the limit.

The advantage of infusion is that it takes a short time, and it is the strongest equipment to be created, but the disadvantage is that the popularity is low, and the craftsman must have internal qi, otherwise it cannot be completed.

All the craftsmen of Zhao Kingdom combined, it is difficult to say whether they can make up five hundred craftsmen with internal energy, and it is impossible to pull them all over to build equipment.

"What if we arrange for a martial artist with internal qi to assist the craftsman?" Lin Xiangru asked. He has realized the importance of this technology, and even if the standard equipment improvement is not so large, it is still a milestone improvement compared to the current one.

Zhao Guo didn't have so many craftsmen with internal qi, but if he was just a martial artist, he could still make up a lot.

"Xiangguo, the kid hasn't tried." Mrs. Xu shook her head.

"Try it, whether you succeed or not, this king will count you as a great achievement." Zhao Kuo said.

"Thank you, Your Majesty." The excitement on Mrs. Xu's face became more and more obvious.

"Of course, this technology can't be unappreciated, this king is ready to crown you as a thirteenth-level knighthood left master, the same as your father. Your kid is the only person in the history of my Zhao Kingdom who has been promoted to the title twice in one day. And at the age of sixteen, he obtained the title of Zuo Shi, which can be regarded as a beautiful talk. This king is waiting for the day when you will be crowned a marquis, or even a duke. Zhao Kuo said to Mrs. Xu.

"Boy, thank you." Mrs. Xu said excitedly. Being a craftsman was something he couldn't have imagined before, and now it seemed that he was really not far from his goal.

Although it is more difficult to rise to the rank of knighthood, he is only sixteen years old, and he still has a lot of time.
