"Imperial mausoleum? The mausoleum of an ancient emperor?" Qin Yu stepped out from behind Jiang Yao, looked inside, and was startled.

"That's right. Legend has it that this place was the capital of the ancient dynasty. It was called Guanzhong. It's not surprising that there are imperial mausoleums there. I didn't expect it to be occupied by a group of sand ghosts and turned into a ghost cave."

Qin Yu is obviously very knowledgeable and knows nothing about ancient history. At least he knows what an imperial mausoleum is.

Jiang Yao looked at the murals on the left and right passages and said with certainty: "Yes, this is an imperial mausoleum. The reason why those sand ghosts can survive is because they occupy the imperial mausoleum..."

He pointed at his feet: "This is a Yin point, where the cold heart lies. Logically speaking, it shouldn't be used as an imperial mausoleum, but it has become an imperial mausoleum. It's a bit weird."

This tomb is grand in size, but the coldness of the tomb is contrary to the requirements of the imperial mausoleum.

Although the imperial mausoleum is a tomb, it is completely different from ordinary tombs. It requires a "flying dragon in the sky" and abundant yang energy.

As the two of them were talking about this, they suddenly heard a strange sound coming from the depths of the ghost cave, as if someone was sighing quietly.

Hearing what sounded like a sigh, the two of them couldn't help but feel a little nervous.

Qin Yu said: "Compared with the outside, it's not very comfortable here. It's cool and sweat-free. I don't want to go out."

Jiang Yao suddenly squatted down and found a line of footprints on the sand beside the tomb passage.

"Brother Qin, look at these footprints."

Qin Yu knelt down and took a closer look, and said slowly:

"Only a noble lady can afford to wear jade-like clogs. She is about sixteen or seventeen years old. She has a well-proportioned figure and is used to holding things with her left hand. She has a graceful gait and is confident. She seems to be familiar with this place."

"She entered the imperial mausoleum several months ago and has never gone out or returned the same way. In addition, she may have left these footprints on purpose."

After he finished his analysis, he looked up at Jiang Yao and said, "I can see this, what else can Zhongda see?"

Jiang Yao nodded: "Brother Qin's analysis is thorough and complete. I have nothing to add."

From the analysis of the footprints, the owner of this line of footprints is a girl of sixteen or seventeen years old. The footprints are neither deep nor shallow, indicating that she is neither fat nor thin. The footprints on the left are slightly darker, indicating that she is accustomed to carrying things with her left hand or shoulder.

A graceful gait means that the left and right footprints line up in a straight line, indicating that the person is walking in a cat-walk.

As for self-confidence, it is because the footsteps hardly stopped on the spot or hesitated, but entered the imperial mausoleum at a leisurely pace, showing that he had the pearl of wisdom in his grasp.

This may also be because she is no stranger to this imperial mausoleum.

To sum up, Qin Yu's analysis can be said to be very accurate and there are no omissions.

Qin Yu said: "If my guess is correct, these should be Yan Lazi's footprints. She walked along the innermost side, and she should have deliberately left clear footprints so that the footprints would not be destroyed and could be seen by those looking for her."

"There is one more thing that needs to be explained. We found this place accidentally, and she should know about it, or come here directly."

"But - if she doesn't come out for so long, will she..."

Jiang Yao looked into the depths of the imperial mausoleum and couldn't help but feel excited and worried at the same time: "She should be fine, I believe her."

He also thought it was Yu Kuan because Yu Kuan was really used to holding things with his left hand.

Qin Yu shook his head and did not comment on Jiang Yao's words.

He wished that Yu Kuan would be unlucky. What he was concerned about was whether anything was found in the imperial mausoleum.

However, if Yu Kuan dies inside, how can he and Jiang Yao survive?

"Let's go in. Yu Kuan dares to go in alone, what are the two of us afraid of?" Jiang Yao walked inside with two guns in hand.

The two of them walked deeper and deeper. At first they felt cool and refreshing, but soon they felt the chill and shivered.

"Why is it so cold in the depths of the imperial mausoleum? Isn't it really chilling?" Qin Yu couldn't help but say.

Jiang Yao frowned: "It must be a chill. This is the imperial mausoleum of the Great Yin. Who is buried there? Could it be..."

Jiang Yao suddenly stopped and said, "Brother Qin, please help me recall my memories. Apart from the big sand dune where the imperial mausoleum is located, are there any other big sand dunes outside?"

Qin Yu shook his head and said: "No. As far as the naked eye can see, I remember there is only this big sand dune, and the surrounding area is very flat."

Jiang Yao muttered: "This is strange. I am sure this is an imperial mausoleum. But there are many accompanying tombs in the imperial mausoleum, or in the entire mausoleum area, there is rarely only one imperial mausoleum alone."

Qin Yu's eyes flickered and he said with admiration: "Zhongda knows a lot, he is really young and profound. But why are you so sure that this place is an imperial mausoleum?"

Jiang Yaodao: "I have seen it in ancient books, so I am sure."

Qin Yu said: "I only know the existence of the imperial mausoleum. I don't know what the imperial mausoleum looks like at all. But I know that people should not be buried here."

"I also know something about tomb repair. In my opinion, rather than burying noble people here, it is better to say that something is locked up, for example..."

"Fire Origin Pearl!" Jiang Yao blurted out, "This imperial mausoleum is probably an illusion, just to hide the Fire Origin Pearl."

Qin Yu nodded: "It's very possible. No high-level ring can store fire beads for a long time. But this tomb with the cold heart of the earth can!"

"That should be correct. Yu Kuan came here to look for the Fire Pearl. It's so cold here, which means the Fire Pearl may have been taken away."

At this moment, Qin Yu was shivering with cold, and Jiang Yao also started to shiver.

However, we have not yet entered the deepest part of the imperial mausoleum.

"No way." Qin Yu stopped, "If the person who went in is really Yu Yan, then she must have brought something warm. Her left hand..."

"The thing on her left hand is not light. It must be a cold-proof treasure such as the spirit mink fur. She wears warm clothes to enter, but we are freezing to death."

Qin Yu was very resentful towards Yu Kuan.

The two of them walked another mile, Jiang Yao's hair was covered with frost, and Qin Yu was too cold to move his legs.

Jiang Yao couldn't bear it anymore. It was at least 100 degrees below zero here. If he continued walking, he would freeze to death.

Yu Yan wouldn't know, would he freeze to death inside?

Thinking of this, Jiang Yao felt that his heart was frozen.

"Zhong...Da, don't...leave again, it's too cold!" Qin Yu said from behind.

After he said this, he turned around with difficulty and returned the same way.

Ginger Yao was also very cold, so he had no choice but to follow him out first.

As soon as he left the tomb passage and returned to the ground, Qin Yu couldn't help but open his arms, embrace the hot rolling sand, and said with a smile: "Warm! Warm!"

The ginger medicine is also very comfortable to inhale, warm and comfortable.

It was really freezing at that moment. If we were a real mortal, we would have been frozen into several pieces.

The two of them "basked in the sun for a while," and the chill on their bodies was quickly driven away by the wind and sand, and soon they felt the unspeakable heat again.

So hot!

The two of them went into the ghost cave again and stayed in the shallow part of the tomb passage without going deep. It was neither cold nor hot here, which was the most comfortable place.

Their bodies felt comfortable, their minds were clear, and they discussed their next plan.

…

"...I know that Zhongda was originally looking for Yan Lazi, and you must go in. I don't advise you either." Qin Yu sat cross-legged on the ground, writing and drawing on the ground.

"However, the extreme cold in the depths of the imperial mausoleum is not something we with forbidden cultivation can bear. If we must go down, there is only one way."

Jiang Yaodao: "I would like to hear the details."

Qin Yu pondered and said: "The only way is to think of a way to cause enough damage at the top of the key pass of the tomb passage to let the sand flow in and affect this chill."

"The restrictions on this imperial mausoleum must have been relaxed or even abolished a long time ago. It is not too difficult to destroy it. Just use your pistol. Your pistol is very powerful. If you shoot it a few times, it will be almost done."

Jiang Yao said in surprise: "Will this method work?"

He immediately thought that Qin Yu was cheating him and wasting pistol bullets.

"It should be feasible." Qin Yu nodded, "In order to complete the mission of the saint, I often organized people to excavate various ancient tomb sites, and I encountered Han Xin..."

"You may not be aware that the cold power of Han Xin was originally the core of the natural cold zone. Han Xin is often targeted and exploited by others. Once the pattern changes, Han Xin's direction will change."

Han Xin is the center of the natural cold formation? Is there any direction?

This was the first time Jiang Yao heard this statement. His understanding of the true world was still inferior to Qin Yu's.

Qin Yu continued: "According to our speculation, if Han Xin is used to seal the Fire Yuan Pearl, then after the Fire Yuan Pearl is taken away, the cold realm will have no resistance, and the cold power will definitely be unleashed."

"But precisely because of this..."

Jiang Yao understood, "Because of this, the internal structure of this imperial mausoleum has been frozen by the cold zone without the control of the Fire Yuanzhu, and has become very fragile?"

Qin Yu smiled and said: "Yes, you are very smart. Without the Fire Yuan Pearl, how long can the imperial mausoleum with loose formations last in such a terrifying cold region, no matter how strong it is?"

"In my opinion, although this imperial mausoleum is deep enough, it is riddled with holes and is in danger. As long as a roof is opened from the tomb passage to the ground, and sand is poured in, the pattern of Han Xin will change, and the direction will change."

"The direction of the cold heart is the strongest point in the cold region. Only when the direction changes can we go deep into the tomb passage."

Jiang Yao thought it made sense and decided to give it a try.

Qin Yu said with great anticipation: "Also, I don't care about Yu Kuan, but I know that in cold areas, there is often too much ice. As long as we take one piece, we will not be afraid of the heat at all."

Of course he was so proactive in coming up with ideas because he wanted to get something that could withstand the heat and cold.

"Okay, let's go in again." Jiang Yao said, "But if Yu Kuan is really inside, will the imperial mausoleum collapse? She..."

Qin Yu said with a smile: "You are so caring that you are confused. Yan Lazi obviously came prepared. A human spirit like her should have obtained the Fire Yuan Pearl and left through another exit."

"It's totally unnecessary for you to worry about people like her. Hey, you are still an honest person."

Jiang Yao's face looked a little ugly, so he walked down again without saying anything to Qin Yu.
