Zheng Xiangtai's residence did not seem to be too far from Gongsun Xia's courtyard, and after about half an hour, Wang Wu rushed back.

He was holding a square wooden box in his hand, and when he opened it, there were several sheets of oiled paper that had been clearly torn.

"I originally wanted to frame this piece of oil paper neatly and save it again, but I wasn't quite sure which side was the front side and which side was the back side, so I packed it up like this!" Zheng Xiangtai said, handing the wooden box to Ding Sicheng, "It's also fortunate that this is the case! Otherwise, if it is framed, I will have to bother to open and frame it today in order to compare it with the other complete oil paper!"

Ding Sicheng nodded, and with his gloved hands, he carefully picked up the torn oiled paper and examined it.

Indeed, there are simple lines and faint ink on those few pieces of oiled paper.

Ding Sicheng asked Bai Yang Xiang Aiguo to find a clean sheet in the closet, spread it on the bed board, and then carefully spliced the torn oiled paper on the sheet into a whole sheet.

Zheng Xiangtai seems to have seen this piece of paper many times, so he is familiar with the road and quickly completes the splicing.

But because he has seen it too many times, this torn oiled paper has been crumpled to a slight hair, not only the transparency is much worse, but some lines and splashed ink are also quite blurred.

Ding Sicheng held the other piece of undamaged oiled paper in his hand, and carefully compared it with the oiled paper spliced on the bed sheet.

Bai Yang's heart moved, and he said: "This oil paper is translucent, do you want to look at the two pieces of paper together?"

Ding Sicheng nodded and said, "It should be like this, so I have to align in the direction!"

As he spoke, he turned the oiled paper in his hand upside down and held it again, and then he gently and gently covered the oiled paper in his hand on the oiled paper spliced below.

The miracle appeared in front of me in an instant, the lines of the two sheets of oiled paper overlapped with the splash of ink below, and the originally intermittent and meaningless lines became a whole pattern that crossed and connected with each other. And those meaningless splashes of ink have also become undulating mountain graphics.

What's even more wonderful is that at the top of the oil paper, several seal characters suddenly appeared. Bai Yang carefully identified it, vaguely like the five words "Heavenly Master Immortal Palace Map".

He could recognize those four words, and Ding Sicheng and Zheng Xiangtai could naturally recognize them more easily.

Zheng Xiangtai even bumped into Ding Sicheng very recklessly, stood directly in front of the two sheets of oiled paper stacked on top of each other, and blurted out: "Heavenly Master Immortal Palace Diagram, my God! Could this be ...... Gongsun Old Thief deceived my seven or eight junior brothers back then and didn't know whether Yuan Tianshi's underground palace map was alive or dead, how is this possible?"

Ding Sicheng glanced at him, slowly moved along the overlapping complete lines with the tip of a finger, and said, "There seem to be two words here, but they are too blurry to see clearly, you have to find a magnifying glass to see it!"

"This also blames me, I have been studying these torn pieces of oil paper over and over again over the years, and I can't see clearly in many places!" Zheng Xiangtai said with annoyance.

"It's okay, wait until I take it back and study it slowly with professional tools!" Ding Sicheng opened his mouth to answer, "It's just...... You have to lend us Master Zheng's torn oil paper to see for two days, or if Master Zheng has time, he can also study it with us!"

"I'm with you!" Zheng Xiangtai said immediately.

Ding Sicheng nodded, and ordered Xiang Aiguo to close the cellar door, he put away the complete piece of oil paper by himself, and Zheng Xiangtai repacked the torn oil paper into the wooden box that Wang Wu brought over.

Several people walked out of the bedroom and into the courtyard. Xiang Aiguo closed the door, and Poplar jumped onto the courtyard wall and pulled the rest of the people out of the courtyard one by one.

On the way back to the building where the grave search team was located, Ding Sicheng asked, "Does Master Zheng have any thoughts on the maps presented on these two pieces of oiled paper?"

Zheng Xiangtai had been thinking about it for a long time, and when he heard Ding Sicheng's question, he said with a wry smile: "Back then, Gongsun Xia found my master and said that he got a map of the Heavenly Master's Immortal Palace, which clearly drew the underground palace map of Yuan Tiangang, the most famous master of fate from ancient times to the present. My mentor asked him to take out the map and look at it, but the old thief resolutely refused. But he said the truth, and he did not allow my teacher to believe him. As a result, my mentor ordered my seven brothers and sisters to follow Gongsun Xia to excavate this Yuan Tianshi underground palace. But this time, my seven brothers and sisters have never heard from me again. ”

As he said this, a sad look on his face.

Ding Sicheng was silent. Bai Yang couldn't help but speak: "If this map is really the map of Yuan Tiangang's underground palace that Gongsun Xia led Master Zheng and several brothers to jointly excavate, then this map is useless, why does Gongsun Xia still treasure it? Also, those cultural relics we found in the cellar, although they are very precious, but most of them have already been determined, and it can be basically determined that there are no cultural relics in Yuan Tiangang's underground palace, so where did Gongsun Xia hide these cultural relics?"

When he asked, several people were silently pondering and unable to answer.

Instead, Wang Wu interjected and said, "Could it be that the old thief of Gongsun has already sold the cultural relics in Yuan Tiangang's underground palace?"

"Unlikely!" Bai Yang shook his head, "From the artifacts in Gongsun Xia's cellar alone, it is already known that he was chased too closely by enemies like you, and he had no chance to sell the Chinese objects in his hand, so that he was obviously living in poverty, but there were a large number of treasures hidden in the cellar." What's more, since he risked forming a mortal enmity with Master Zheng's sect, killed several of Master Zheng's brothers and sisters, and monopolized the treasures in Yuan Tiangang's underground palace, then this treasure must be extremely precious, and it is likely that all the treasures in his cellar cannot be compared to it combined. But if he really wants to sell such a shocking cultural relic, not to mention Gongsun Xia's other enemies, even your master and apprentice shouldn't be unheard of at all, right?"

His words made Wang Wu speechless.

Zheng Xiangtai thought about it for a while, and it wasn't until the group walked into the courtyard of the building where the tomb search team was located that Zheng Xiangtai suddenly said: "The question that Little Brother Bai mentioned just now is very reasonable, I think ...... Does Little Brother Bai want to say that Yuan Tiangang's underground palace, Gongsun Lao Thief is likely not successful in stealing and digging at all?"

"That's exactly what I think!" Poplar nodded, "We've also unearthed some very dangerous big fights, such as ...... Wang Jiutang Tomb, I think Master Zheng should have heard of this matter, we died nine times in Wang Jiutang Tomb, and there were eleven first-class inverted bucket masters who went in at that time, and only four or five came out alive in the end. And Yuan Tiangang is a celestial master-level figure who is more famous than Wang Jiutang, and the complexity of the organs in his underground palace is probably even better than that of Wang Jiutang's tomb, right?"

Zheng Xiangtai was speechless for a while.

Ding Sicheng glanced back, smiled and asked Zheng Xiangtai to go upstairs first.

Upstairs, Ding Sicheng opened the office door, and while instructing Xiang Aiguo to prepare tools, he asked Zheng Xiangtai to sit down on the sofa.

Ding Lingling made tea, but Zheng Xiangtai had no intention of drinking it, so he thanked him and put the teacup aside.

Ding Sicheng took out the complete piece of oiled paper and spread it on the desk, and then asked Zheng Xiangtai to splice and stack the torn pieces of oilpaper on the complete oiled paper.

But those pieces of torn oil paper have been kneaded to see that the transparency is very poor, so I can only pick up the complete map, first put the torn oil paper on the desk and put it neatly, and then adjust the direction of the complete oil paper to cover it.

After that, Ding Sicheng took the magnifying glass and other objects handed to Xiang Aiguo, and gathered with Zheng Xiangtai to carefully survey the map inch by inch.

A few young people couldn't intervene, so they could only keep quiet and wait aside.

For a long, long time, finally, Zheng Xiangtai and Ding Sicheng stood up straight at the same time, the two looked at each other, and then nodded together.

"How is the teacher?" asked Xiang Aiguo immediately.

The location is near Huojing, Sichuan, which is now Qionglai County. It also happens to be the hometown of the legendary Yuan Tiangang, and it is said that Yuan Tiangang was buried there after his death!" Ding Sicheng said.

"Yes!" Zheng Xiangtai smiled bitterly, "For thousands of years, I don't know how many inverted masters have wanted to find Yuan Tiangang's tomb, but there has never been any result. So much so that the old thief Gongsun mentioned to my mentor that he found a map of the heavenly master and the earthly palace, and my mentor knew that he had a despicable temperament, so he still moved his mind and arranged for several of my brothers to follow the old thief of Gongsun to Sichuan, and among them was the son of my mentor who valued him the most......"

When Zheng Xiangtai said this, he suddenly choked up, and he couldn't say the next words.

"But now that the drawings are here, and Gongsun Xia has obviously torn them up, but they have been re-collected, and he is reluctant to destroy them completely, what does Master Zheng think this means?" Ding Sicheng asked.

This illustrates...... It is very likely that the old thief of Gongsun took a few of my senior brothers and ...... at all There was no success in digging up Yuan Tiangang's underground palace!" Zheng Xiangtai took a breath and replied slowly, and quickly turned his face to look at Bai Yang, "Little Brother Bai raised several questions before, he must have a very clear idea, right?"

"Almost!" Bai Yang nodded, "I don't think Gongsun Xia killed several of Master Zheng's senior brothers, but ...... Yuan Tiangang's underground palace was too dangerous, and several of Master Zheng's brothers were trapped in it and couldn't come out. Only Gongsun Xia ...... Maybe he was more cunning, and when he saw that something was wrong, he immediately left several of Master Zheng's brothers and sisters to escape alone, which barely saved his life. ”

"If that's the case, then why didn't Gongsun Xia go and explain it to my mentor? Even if my mentor was angry with him because of the deaths of my junior brothers, as long as he handed over this Yuan Tiangang underground palace map, he should be able to save his life! But why did he hide and let everyone in the inverted dou world think that he killed my junior brothers?"

Zheng Xiangtai's questions were very sharp, but they were also reasonable.

Bai Yang's heart turned around, turned his head to glance at Ding Sicheng, Ding Sicheng smiled and said: "If you have any ideas, just say it!"

Poplar nodded, sorted out his thoughts a little, and then spoke cautiously and slowly.

"I think it's very likely that Gongsun Xia saw extremely strange and terrifying things in Yuan Tiangang's underground palace, so terrible that he felt chills when he thought about it! He may even be afraid that the things in the underground palace will come out and ask for his life, so that he has been hiding in Tibet for so many years, in fact, what he is really hiding is not only his enemies, but also the terrible things he saw in the underground palace!"

After hearing the words, Zheng Xiangtai and Wang Wumian looked at each other and couldn't make a sound.
