"So, please tell me." Gu Yun smiled slightly.

Cheng Yu sorted out his thoughts and finally said, "Twenty years ago, there was a master who helped me successfully destroy the old rival of Chutian Group, and also helped Ding Chen become the top five major consortium in China. As a result, I became close friends with him."

"One day, he said he was leaving. Before leaving, he gave me a sword, saying that the sword contained the secret of immortality and he couldn't guess it thoroughly, so he gave it to me."

"At that time, I thought this was just a joke, and I didn't take it seriously. Until one day, Xue Qing came back from abroad on holiday and saw this sword in the study. She felt curious and took it down and played for a while."

"As I was playing, I didn't know what happened, the hilt of the sword suddenly cracked. I went over and found a map inside. That map was the location map of the ancient tomb."

"I believe you have guessed everything that happened later." Cheng Yu took a sip of tea and continued, "All those who have been there have been old all night. Some even died there directly."

Gu Yun listened quietly, with no expression except nodding slightly.

But my heart was turbulent.

So, is that an ancient tomb?

Then that sword...

After pondering for a while, he asked, "Is that sword called the Sword of Cause and Effect?"

"That's right." Cheng Yu suddenly smiled, "Mr. Gu, it turns out that you know the sword of cause and effect?"

Gu Yun did not answer, but blurted out, "That sword is now..."

He was about to ask where he was, but then he realized that something was wrong, so he immediately changed his words as if nothing had happened, "It's no longer a secret."

Gu Laogou had to admit that his obsession with the sword of cause and effect was indeed too deep, and he almost made a mistake that only children would make.

Judging from Cheng Yu’s question just now, he may not have known that the Cause and Effect Sword has something to do with him, or that he is looking for the Cause and Effect Sword.

If you ask him where the sword is, not only will it be impossible to get an answer, but once the old fox knows that the sword is important to him, he will definitely use it to control himself.

Do you think you are not sincere enough? No one can see only underwear. If you reveal this point again, it will be really a t-tip.

Cheng Yu probably didn't hear anything, but said along the words just now, "Yes, the sword of cause and effect is no longer a secret, it's just a tool that hides the map."

Gu Yun smiled slightly, picked up the teacup, but put it down again.

Is the sword of cause and effect just a tool?

Cheng Yu's words reminded him.

If the Sword of Cause and Effect is just a tool for Hidden Map, then did Lin Jianguo have one in his hand at the beginning?

Do all those who obtain the map have a karma sword in their hands, and their maps are obtained from the hilt of the sword?

In this case, those karma swords should be fake?

Including the one Lin Ruoyin got before?

So, are these swords sent out by the same person, such as the master Cheng Yu mentioned?

Who is he and what exactly is he going to do?

For a moment, countless questions churned in Gu Yun's mind.

Seeing Gu Yun picking up the teacup and putting it down, Cheng Yu couldn't help but smile and said, "Mr. Gu, you can drink tea with confidence. The old man also hopes that you will help your granddaughter win the bet. Come back and come to the group to help me deal with those people, haha."

Gu Yun smiled without comment, but still refused to drink tea.

Old Dog Gu has never seen ghosts for hundreds of thousands of years, but he has seen them many people and half ghosts. Cheng Yu belongs to this. This old man is definitely not a good man. Don’t look at him smiling like a grandfather.

Who knows what he will do when he is about to die.

Cheng Yu was sucked away from his life in the ancient tomb. Now he knows that he has something to do with the ancient tomb. If he is in a hurry and feels that those life is obtained by himself, he may be able to turn over himself and use it to slice it as ginseng to make tea.

Of course, this possibility is very small. One of the old men hoped that they would help Cheng Xueqing save the ancient town. Two of them still had too many things to understand and wanted to find out from themselves. Thirdly, even if the ancient tomb had something to do with him, it might not be the kind of relationship that would make him live forever after eating.

However, with Gu Laogou's prudence, he will not take even a little risk - unless the expected returns far exceed the risk.

Just as he thought of this, Cheng Yu said, "Mr. Gu, the old man has answered many questions. Should Mr. Gu answer a few?"

Gu Yun nodded slightly and said lightly, "Master, please tell me, I know everything I know."

This is not a lie, but unfortunately he really doesn't know anything.

A hint of joy flashed in Cheng Yu's old eyes. He really had too many questions to ask Gu Yun.

As soon as there were many questions, he had no idea. He spent more than ten seconds to sort out his thoughts, and then said, "I want to ask Mr. Gu, is that expert still in touch with you?"

Gu Yun didn't know why Cheng Yu believed that the "expert" would have something to do with him. Could it be that Cheng Yu thought that he, like that expert, had ordinary people different from this world, so he would definitely know him?

This is a bit far-fetched reason.

Or is it that "expert" who mentioned himself to him?

Old Gou Gu couldn't show his bottom, so he smiled mysteriously and said, "I don't know who you mean?"

"Mr. Gu, don't joke. The old man pointed to it, of course, the master who gave me a sword."

"There are so many experts in this world, how do I know which one you are talking about?" Gu Yun continued to practice Tai Chi.

Cheng Yu frowned slightly, and then said, "What the old man said is the master who lacks front teeth. He calls himself 'Mr. Zhu' to me, but he doesn't know his real name."

"Mr. Zhu, are there any front teeth?" Gu Yun smiled when he heard this, "That guy hasn't seen you for a long time."

I haven't lie, I haven't seen you for a long time.

But I haven't seen it before.

He can't blame him if he only said half of the words, after all, he only promised to speak everything, but he didn't say everything.

But to be honest, Mr. Gu must say that.

He was almost naked in front of Cheng Yu before, but now he has to wear clothes one by one so that Cheng Yu can no longer see through him.

Only if a Gu Yun who cannot see through can Cheng Yu show sincerity in cooperation, otherwise would it be so simple to be this old man who has been in the mall for most of his life?

Upon hearing this, Cheng Yu asked unwillingly, "Can you still contact me?"

It is probably because he knew that he might not have much time left, so he was so anxious. After all, the cause of everything was that "expert". Now that he has fallen into this field, how could he not want to ask him "why" again?

"Of course I can't contact you. How could someone like him leave contact information?" Gu Yun asked back.

Cheng Yu nodded, "That's right... Then, the second question is, Mr. Gu knows what is in the ancient tomb? Why does it attract life, and why do some people think it hides the secret of immortality?"

Gu Yun thought to himself that you asked the right person. This is the first time I have heard of the ancient tomb. I want to ask where you are.

"These are two questions." Gu Yun smiled slightly, "But I can answer you. What exactly is in the ancient tomb? I can't tell you now. As for the second question... do you know the conservation of energy?"

Old Gou Gu didn't say anything, but seemed to know everything.

"Energy conservation?" Cheng Yu was slightly stunned, then smiled slowly, "I understand, I understand... but Mr. Gu, what is in the ancient tomb? If you think it's OK, please tell me."

He paused and smiled bitterly, "If you can know this secret before you have a lifetime, you will die... and be in peace."

"Okay." Gu Yun nodded, "Do you have any questions?"

"The last question." Cheng Yu took a sip of tea, calmed down, and asked again, "Why should I help Xueqing?"

Gu Yun thought to himself, he asked well.

But he didn't hurry to answer and asked, "My grandpa, I want to ask a question before this question."

"Haha, even if Mr. Gu asked, the old man knew everything."

"How much do you know about Professor Sun's death?"

Since Cheng Yu was interested in exchanging questions, Gu Laogou would have to ask this question that had been hidden in his heart for a long time.

Cheng Yu looked at Gu Yun in surprise, pondered for a while, but said, "Professor Sun wanted to go to the ancient tomb to see what happened, but he died of a heart attack in front of the stone gate. I also heard about this. When he told me this plan, I advised him not to go."

Gu Yun understood a little, and first of all, Professor Sun also knew the existence of this ancient tomb.

So, after Professor Sun's death, the person who was almost exactly the same as Professor Sun, but was just an older person...

It's probably his son!

A reasonable explanation is that when Professor Sun went to excavate the tomb, he specially brought his son Sun Zhenmin with him. As a result, he was too old and could not withstand the chance of extracting life as soon as he approached the tomb, so he hung up directly.

In order to bring out his body, Sun Zhenmin was taken out with a lot of vitality and became like that in an instant.

Because the father and son look very similar, although there are some differences between them, Professor Sun, whom he saw, was born after death, so he naturally attributed these differences to the differences between people after death and before his death, and mistakenly believed that the two were the same person.

However, something strange is that Sun Zhenmin's legs and feet were surprisingly fast after he got old. That day, he even let him run away when he chased out at his own speed.

Are there any more secrets about Sun Zhenmin?

He has been to the ancient tomb, but instead went to find Lin Ruoyin. What is the reason?

It seems that it is necessary to look for him again.

After Cheng Yu finished answering, he looked at Gu Yun who was thinking and asked, "Mr. Gu, can you answer my question now?"

"Of course." Gu Yun said, "You have heard carefully. I did this not to help Cheng Xueqing, but to help you."

Cheng Yu was stunned after hearing this, and then smiled, "Why, why did Mr. Gu help the old man? The old man has nothing but money now."

Gu Yun thought to himself, just pretend.

Even Professor Sun’s son knows so much about the ancient tomb. Do you know this?

Then the "expert" has not revealed any other information for you for so long?
