"The city lord kept Xie Rui in exchange for more supplies?" Chu Yun was a little puzzled. According to Su Yu's past personality, Xie Rui's bones were chewed clean by wild beasts.

What Su Yu wanted was not just that little material.

"Jin State has an iron-smelting technique that can maximize the utilization of mined iron ore." Although Chu State also has iron-smelting technology, it is still inferior to Jin State.

During this period of time, she has repeatedly asked Xie Rui's party members to test their bottom line. She wants to know what steps these people can take to save Xie Rui.

So before that, Xie Rui must be alive.

If the guard's actions were instigated by others, it means that there are people with different intentions hiding around her.

Chu Yun did not expect that Su Yun would actually want Jin's iron training technique, because with this iron training technique, Jin's weapon stock is larger than that of Chu and southern countries, and in addition, Jin has not had any wars in the past few years, so it can be inferred Jin's weapon reserves are higher than those of the other two countries.

Such an important technology, would Jin really hand it over for a prince?

Chu Yun thinks this possibility is extremely small, but it’s okay to try, what if it happens?

Xie Rui woke up early the next morning.

He opened his eyes, and a slender figure instantly appeared in his pupils, and the hairs on his body stood up instantly.

Su Yan turned around slowly and looked down at him, "I didn't expect the person who wanted your life to sneak into my city."

Xie Rui's face changed, "What do you mean? Don't you want me to die?"

Su Yan raised the corners of his lips coldly, "I want you to die, and you will not live until now, First Prince, you are with me, living is more valuable."

Xie Rui was silent. It was undeniable that what Su Chen said was reasonable, but he had too many enemies, and he couldn't think of anyone with such long hands who could send someone to this ghostly place to kill him.

Su Yan sat down beside his bed, even if he just sat there, Xie Rui felt a pressure that couldn't be ignored hitting him, making him feel weak all over.

"Actually, I don't want to be an enemy of Jin. It's just that you have done so much harm to my citizens before, and you always have to make some compensation."

Xie Rui's heart was racing, and he felt that there was something in Su Yun's words, "Just say what you have to say."

"I intend to let you go, it depends on whether the people on your side have the sincerity."

"what do you want?"

"Iron practice."

"What did you say?" Xie Rui thought he had heard it wrong.

He had thought that Su Yu would ask for all kinds of gold and silver treasures, but he didn't expect her to be so courageous. Iron training is the main gate of Jin State, how could she easily take it out?

"Do you think that iron training is in my hands, and I can give it to you if you want? You really think highly of me!"

Su Yu was not in a hurry, but said leisurely: "If this thing is so easy to get, it is not worthy of the eldest prince's life. I heard that Jin's health has been declining in recent years, and he has become more and more powerless about state affairs. , presumably it won’t be long before the crown prince is established, if the First Prince stays in my city all the time, I’m afraid I’ll miss the good time.”

Of course Xie Rui knew what Su Yun said was true or false, otherwise he wouldn't have lost a lot of his hair in such a hurry.

"You can think about it carefully. If you think it through, write a letter to your people. I believe they will try their best to rescue you."

After finishing speaking, Su Yu turned and walked out, leaving Xie Rui alone to weigh the pros and cons.

Iron smelting is definitely difficult to obtain, but compared with my own life, it is nothing at all.

Without thinking about it for too long, Xie Rui sent someone to send a message to Su Yu, saying that he agreed to Su Yu's request, but the premise was to meet with his cronies, and some things needed to be said to the other party in person.

"This matter is no small matter. It may not be easy for them to take such a big risk with just a letter. The city lord should understand what I mean."

Stealing and practicing iron art is a capital crime for the nine clans.

Su Yu agreed to his request.

After receiving Xie Rui's letter, Mr. Wang sent it to Zhou Wei immediately.

"Third Master, take a look, is this true or false?"

The letter stated that Master Wang was to go to the Northern Wilderness to join him in three days, but he was clearly still in the hands of those people.

Zhou Wei looked at the content of the letter repeatedly, and was sure that it was Xie Rui's personal letter.

"I go."

Master Wang was shocked, Xie Rui was already in the hands of the other party, if he was paying a week to get in, then he really didn't have to go back.

"Third Master, there may be fraud in this, you should think twice."

Zhou Wei shook his head, Xie Rui didn't know that he had arrived in the border city, and the people in the Northern Wilderness certainly wouldn't know either, so there was no possibility of using tricks to lure him there.

The other party must know that Mr. Wang is just a errand person, and they spent a lot of time to catch a errand person for what to do.

From this, it can be inferred that the other party probably really wanted Xie Rui to see them.

So he went and could understand the other party's intentions more clearly.

"Don't be afraid, you can just go down and send a message to our people to see if they have found any useful news."

"Yes, little one, I will send someone to ask about it."

Zhou Wei was not in a hurry, but waited until the time stated in the letter, and then he took a few carts of things to the agreed place and waited.

Qiao Yang had been waiting there early in the morning.

After confirming that Zhou Wei was Xie Rui's man, he took him into the Northern Wilderness and went to Tiankui to support him.

Zhou Wei's eyes were covered the whole time, and he couldn't check the surrounding situation at all.

When Zhou Wei's blindfold was taken off, he saw a figure lying on the bed.

In a few days, Xie Rui's body recovered a bit, but he was still weak.

Xie Rui was a little puzzled when she saw Zhou Wei, she didn't recognize Zhou Wei after his disguise.

Zhou Wei stepped forward and said softly, "Is your Highness alright?"

Hearing Zhou Wei's voice, Xie Rui's eyes showed a look of shock. He quickly glanced at the door, and immediately restrained the look in his eyes, for fear of being seen by others.

"You're here, I'm fine, don't worry."

In a place where no one outside the door could see, Xie Rui held Zhou Wei's hand tightly, and he was eager to know if Zhou Wei could rescue him.

Zhou Weihui held his hand and shook his head slowly at him, "Your Highness, don't worry, talk slowly if you have something to do."

Xie Rui quickly glanced outside the door, "They want to practice iron skills."

Zhou Wei's pupils were shocked, but he quickly restrained his expression, "What a big tone."

"If I get the iron training technique, they will let me go, otherwise..."

"Tell me what you know about this place."

Xie Rui frowned, and said everything he knew.

Zhou Wei frowned after hearing this. Xie Rui has been here for so long before and found out so much?

"Uncle, you must save me!"
