Zhou Wen felt that the iron chain was cold and bone-black. Holding the iron chain was even colder than holding the ice cube. The cold air seemed to drill into the cracks of the bones.

Hui Haifeng laughed and said, "Don't be afraid, the cold air on the iron chain can't hurt your legendary body."

"Why is this iron chain so cold?" Zhou Wen held the iron chain again, feeling like he was putting his hand into liquid nitrogen.

Of course, this is just Zhou Wen's feeling. He has never tried to put his hand into liquid nitrogen.

Hui Haifeng said: "This cave is called Longjing, but there is no water below. There is a very heavy white fog. The white fog is extremely cold. In some places, the temperature is even lower than liquid nitrogen. The iron chain extends all the way to it. It is affected by the white fog and becomes extremely cold. If an ordinary person holds the iron chain, it won't take long to freeze his fingers, but the legendary physique will not be affected too much."

"What is this iron chain for?" Zhou Wen asked while pulling the iron chain up.

"Can you fish?" Hui Haifeng asked back without answering Zhou Wen's question.

"I played when I was a child, but I just played with fishing, so I can't say I can do it." Zhou Wen replied.

"Then you have to study hard. This iron chain is used to fish for things, but it is not fish, but dragons." Hui Haifeng said with a serious face.

"Fishing dragon?" Zhou Wen looked at Hui Haifeng in surprise, hoping that he could make the words clear.

Hui Haifeng explained: "This chain was created by Mentor Mingyuan, just to fish out the dragons in the dragon well."

"There is a dragon underneath? What kind of dragon is it?" Zhou Wen became even more curious.

In this era, any kind of mythical creature may appear, but things like dragons are legendary things after all, and they are probably something that is only available at mythical level, and it is impossible for ordinary people to see them.

"I don't know, this is the inference of Mentor Mingyuan. We have never seen it before. However, the sound of dragon roars often comes from this dragon well. Occasionally, you can see strange light reflected from the dragon well." Hui Haifeng said.

At this time, a lazy voice suddenly interrupted and said, "No one has ever heard the sound of a dragon, so how can he know that it is the sound of a dragon roar? Look, even if there is really something below, it is just a dimensional creature, and it has nothing to do with the dragon in mythology."

In addition to Zhou Wen, there are three students in the laboratory, and the third person who speaks except Hui Haifeng and Jiang Yan.

He looked lazy, put his hands behind his head, lying on a chair, and his legs were casually placed on the table, looking very lazy.

"His name is Zhong Ziya, and he is also a student of the tutor." Hui Haifeng gave a brief introduction.

Zhong Ziya leaned against the chair and greeted Zhou Wen casually: "You are here just right. I used to collect the broken iron chains. Now that you are here, I am considered liberated. I have to thank you for speaking."

"It should be." Zhou Wen had no idea. He held the iron chain and continued to pull it up. He didn't know how long the iron chain was. Zhou Wen pulled it for more than ten meters, but the iron chain was still not over.

Moreover, the place where he held his hands felt more and more cold, making Zhou Wen unable to bear it anymore, so he could only use the Lotus Buddha's energy technique to protect his hands to resist the terrible cold air.

"Senior brother, you cannot use the energy skills when pulling iron chains. This is the rule set by the teacher." Zhong Ziya said lazily. Among the three, he only called Teacher Wang Mingyuan, rather than the tutor he usually used.

"Is there such a regulation?" Zhou Wen looked at Hui Haifeng and Jiang Yan.

Jiang Yan sat aside and read a book quietly, as if he had not heard Zhou Wen's words. He felt like he was not listening to things outside the window and was devoted to reading only the books of sages.

Hui Haifeng was using some equipment to exercise, and while exercising, he said, "Minister Mingyuan is indeed so prescribed, and we have no choice, so you can bear it. Fortunately, the cold air cannot really hurt you, it just makes you feel a little uncomfortable."

"What a weird tutor." Zhou Wen had no choice but to put away the lotus Buddha body and rely on his flesh and blood to fight against the cold air on the iron chain.

The more Zhou Wen pulled, the more he felt that his hands were so cold that he was almost numb and could not bend his fingers. However, Zhou Wen had no intention of stopping and was still pulling the chain.

Hui Haifeng, Jiang Yan and Zhong Ziya all looked at Zhou Wen intentionally or unintentionally, as if they were watching something very interesting.

Zhou Wen pulled it, and the last ten fingers were so numb that they were frozen. When his hand slid, the iron chain that had been nearly a hundred meters long and slid down suddenly.

Hui Haifeng and the other two just watched, no one said anything, nor did they want to help Zhou Wen.

Zhou Wen looked at the chain that had fallen down, but he didn't feel discouraged. He sat next to him for a while and waited for a while. After the cold air of his hands dissipated and his fingers returned to normal, he stood up again to pull the chain.

This time, Zhou Wen was a little stronger than the last time, and he pulled it to more than 100 meters, but he couldn't stand the cold air and the iron chain fell down again.

After Zhou Wen recovered his hands, he went to pick up the chain again. This time he pulled out more than 110 meters, but in the end he could not resist the cold air above, and the chain slid down again.

After pulling the chains repeatedly for seven or eight hours, Zhou Wen still couldn't pull all the chains out.

When Zhou Wen wanted to continue pulling the chains, he saw someone crawling out of the dragon well.

The man was wearing a cold-proof suit and a helmet on his head. After climbing up, he took off his helmet, revealing the gentle face of a mature man. He looked quite young and had long hair and a few strands of dyed white hair, which seemed to add a bit of mature male charm to him, very much like the big stars in previous film and television works.

Zhou Wen thought this was a senior, but he heard Hui Haifeng say, "Teacher, are you back?"

"Is this Wang Mingyuan?" Zhou Wen looked at the man in front of him in surprise, and for a moment he couldn't accept it.

He heard from the princess that Wang Mingyuan was about to retire, and he thought that Wang Mingyuan should be a white-haired old mentor. He really didn't expect that mentor Wang Mingyuan would look like this.

"Is your hands okay?" Wang Mingyuan nodded slightly to Hui Haifeng and the other two, then naturally pulled Zhou Wen's hands, and a warm force flowed into Zhou Wen's hands, and in a moment, the cold air in his hands was dispelled.

"Thank you, mentor, I'm fine." Zhou Wen hurriedly thanked.
