Xie Jun didn't know that besides him, there was another pair of eyes on the roof staring at the iron smelting technique in his hands.
After putting away the iron smelting technique, Xie Jun called in his confidants.
"Your Highness."
"Take your stuff and keep going north."
"yes."
The henchman took the box and left the house.
The figure hidden on the roof quickly ran towards the departing figure.
When the man left the inn, the figure quickly stepped forward and killed him, then threw the body and the box into the space. Then the slender figure quickly disappeared into the thick night.
Xie Jun has been waiting for his confidant to send him a signal. As long as he reaches the designated location, he can set off.
But we waited until the next morning and there was still no news from the other side.
Xie Jun's heart sank. Could it be that someone had seen through his plan and was trying to sabotage it?
Worried that things might have changed, Xie Jun immediately sent a message to his people.
But the reply he received was that the man who had obtained the iron smelting technique did not show up the whole night.
Xie Jun was stunned.
This is impossible! Absolutely impossible!
That was his most trusted confidant, and he didn't believe that he would betray him.
Xie Jun immediately sent people to look for him, but the man seemed to have disappeared without a trace of hair left.
Xie Jun was completely confused. He had originally planned to put on a show, but who knew that he would actually have to look for the iron smelting technique.
How could Su Yu, who had obtained the iron smelting technique, care about their life or death?
After acquiring the iron smelting technology, she was not in a hurry to leave Jin State.
Now is the spring plowing season, and they need a lot of seeds, so when she passed through various cities on the way out, she bought a lot of grain seeds, vegetable seeds, tree seeds, and even poultry. She bought everything she thought might be used.
It was nearly ten days later when she left Jin State and returned to the northern wilderness.
As for what Jin is like now, that is not her concern.
After returning to Tiankui City, Su Yu called Chu Yun to the inner hall.
"Come on, you are educated, take a look at this thing."
No one knew what Su Yu had been doing during the time she was away, so when Chu Yun unfolded the iron-smelting technique and observed it one by one, even someone as calm as him was stunned.
"Iron smelting technique? Jin's iron smelting technique?"
Su Yu ate calmly and nodded, "Yes, it is right."
"The city lord went to Jin State to steal it?"
"Yes and no. Their people stole it themselves and I took it."
Chu Yun: “…”
Although Chu Yun was speechless, he was still excited.
This is the iron smelting technique of the Jin State!
"The city lord never said before why he wanted to release Xie Rui. City lord, has he been planning this for a long time?"
As smart as Chu Yun was, he quickly figured out the connection. Before, he didn't understand why Su Yu let Xie Rui go so easily, but now he thought it must be related to the iron smelting technique.
Su Yu shook her head and nodded. Strictly speaking, it was Xiao Jin who taught her how to play chess.
Xiao Jin wrote to her all the time, complaining about her being perfunctory towards him in various ways. She was really annoyed by him, so she told him about Xie Rui's situation.
At first, Xiao Jin did not respond to this matter, but once he asked her if she really wanted to learn iron smelting, and she said yes.
Xiao Jin told her to do as he said.
It would be very difficult for the Prime Minister's Mansion to obtain the iron smelting technique if Xie Rui was kept in their hands, because the other party would also think that Xie Rui would not die before achieving their goal, and they would only keep trying to save him and delay time.
Xiao Jin asked him to take advantage of the situation, and then let the Red Devil in Jin cooperate with her to complete the rest of the time.
Just at this time, Su Yu learned about the spy from Meng Jiang, and just when he was dozing off, someone brought him a pillow.
Before she let Xie Rui go, she asked Red Devil to tip off Xie Jun about the stupid things Xie Rui had done in the Northern Wilderness. As the two were enemies, Xie Jun would definitely not let go of the opportunity to bring bad luck to Xie Rui.
Sure enough, Xie Jun did not let her down.
Afterwards, she realized that Xie Jun must have also realized that she was just asking the Red Devil to use some far-fetched things to lure Xie Jun. If he didn't have such thoughts, he wouldn't be easily fooled.
At the beginning, Su Yu was not very obsessed with iron smelting skills, but when they opened the mine, they found that the iron ore under the mine might be much more than they imagined. In this case, it was very important to have superb iron smelting skills.
Iron smelting technology is extremely important to the State of Jin, and is divided into three parts. It is indeed difficult to obtain it by simply holding Xie Rui hostage, otherwise she would not have gone through such a big detour.
Although the process is a bit troublesome, at least the result is satisfactory.
As for whether there would be chaos within the State of Jin because of this, it had nothing to do with her. After all, even without her, the king of Jin's eldest sons would not be able to let him live a few more years.
"But City Lord, this iron smelting technique is so important, I wonder how the City Lord will use it?"
Something that could be protected like that by the State of Jin certainly cannot be easily handed over to other people. Even if those people are trustworthy now, what about in the future?
"What do you think?"
Chu Yun frowned slightly. This matter really required careful consideration.
"We can only learn from the model of Jin State and let them divide the work."
"For each step, we train a group of people."
As for those who can master this technology, they need to be restrained.
There are not many people who know how to smelt iron in the Northern Wilderness now. Some of them were brought by her from the State of Chu. The situation in the State of Chu is more complicated. Even if Xiao Jin wants to obtain the iron smelting technique, she does not want to pass it back to the State of Chu now.
"You will bring all the people who will be involved in the iron smelting here tomorrow."
"good."
…
Xie Jun would never have imagined that the iron smelting technique he had worked so hard to acquire would actually be used to help others.
He never expected that he was just putting on a show, but in the end he actually came out to look for the iron smelting method.
"Your Highness, we have searched everywhere he could go, but we can't find any trace of him. Could this guy have betrayed us?"
Xie Jun's expression was almost distorted.
"Dig three feet into the ground to find the person!"
He was glad that he did not tell Emperor Zhaoheng about his discovery of the iron smelting technique, otherwise he would have been digging his own grave.
…
The Iron Smelting Technique described every step and precaution of iron smelting very clearly. Su Yu and Chu Yun spent an entire night separating them.
Su Yu’s plan is to have a small group responsible for each link, just like an assembly line in a large factory.
After they were sorted out, those who were skilled in iron smelting were brought to the inner hall.
"Meet the city lord."
