After hesitating for a moment, Wang Lun looked carefully and said in an uncertain tone, "Is this a snake shed?"

"What is a snake shed?" Xiao Xingzi asked curiously, "I know almost all the things I feel, but I don't know this."

The reason why she asked Wang Lun just now was that her spiritual sense sensed the old object in the room, and she found that she didn't know this.

After all, I lived here with Fairy Tianfeng, after all, it was ten thousand years ago. I might have seen many things before, but now I really don’t remember them.

"Snake sheds," Wang Lun explained, "Many kinds of snakes will shed their skin. They crawl on the ground, and their surface skin is smooth and tough, which can ensure that they do not damage the flesh when rubbing against the ground. You can understand snake skin as the scales on the fish. The scales do not need to be replaced, but the snake skin will gradually age after a long friction with the ground. The snake also needs to replace it with new skin, so the old skin will fade away, and the peeling skin will be the snake shed."

I hesitated before that I felt that this golden, snake-like thing can be understood as a snake-like shed or a strange insect skin molt. Of course, Wang Lun thought that it was a snake-like shed.

"So it was the snake's skin." Xiao Xingzi understood.

After she finished saying this, she stopped the sound directly. After two seconds, the sound appeared in Wang Lun's mind again and turned into an explosion.

"Wang Lun, I remember it!"

Xiao Xingzi shouted loudly.

Wang Lun quickly asked the other party with consciousness, "Xiao Xingzi, what have you remembered?"

He was looking forward to the instrument spirit remembering how to use the energy here.

Xiao Xingzi said happily: "Snake, the owner once left the skeleton of a snake demon underground in the main courtyard."

"The skeleton of the snake demon is buried underground in the residence?" Wang Lun immediately asked, "Is Fairy Tianfeng doing this to use the skeleton of the snake demon to suppress something? Is it not peaceful here and it needs something to carry out some balanced suppression?"

Xiao Xingzi shook her head and said she didn't know.

She just happened to hear Wang Lun's explanation of the snake. When she mentioned the snake repeatedly, she suddenly felt blessed to the heart. She thought of the snake demon and the memories ten thousand years ago.

Then, she explained the relevant information she knew in detail to Wang Lun.

On that day, Fairy Tianfeng left the Ten Thousand Spirits Vase at the beacon position in the lake, and Fairy Tianfeng himself went out. The spirit of the artifact didn't know what the master had experienced. He only knew that it was very late that day, the master came back and took the Ten Thousand Spirits Vase to leave the beacon position and returned to his residence.

Then, the spirit of the weapon sensed with his spiritual sense and "sees" that Fairy Tianfeng shook a storage ring and shook the body of a big snake to the ground.

The snake demon was about two hundred meters long and curled up into a ball. It was forced to squeeze together by the owner and stuffed into the storage ring. After it landed, the owner straightened the snake demon's body, and then used magic power to remove the snake demon's flesh and blood, revealing the snake demon's complete skeleton.

Afterwards, the master dug out a passage about the same size as a snake demon on the ground of his residence, which was about square and penetrated the entire courtyard of the main courtyard, and then buried the skeleton of the snake demon in the passage.

Because the spirit of the weapon has a natural disgust towards snakes, he did not ask the owner why the snake demon skeleton was buried underground in the residence.

After listening to Xiao Xingzi's story, Wang Lun didn't know anything else, but one thing was certain: Fairy Tianfeng would not do purposeless things casually.

At this moment, Wang Lun no longer continued to use the Ten Thousand Spirit Treasure Bottle to absorb the energy contained in the items in the room.

After measuring, I checked the rear windows of the three utility rooms and selected a place that is most suitable for observing the main courtyard.

The location of the utility room is slanted behind the main courtyard, and the middle area is connected to the pond and the pavilion.

Choose a location behind the custard room and you can see about half of the front door of the main courtyard.

Wang Lun would not choose to leave the custody room and risk going outside to observe and get the opportunity to fully monitor the main hospital. If he does that, once he is discovered, all his previous efforts will be wasted.

Staying in the custard room, as long as you converge your breath and use your mana within a small range, the custard room will be his natural shelter, which will facilitate his observation of the main courtyard.

Wang Lun found a table and changed it. After sitting on it, he could see outside without bent down and maintain a more comfortable posture.

Then, Wang Lun opened his eyes and observed while practicing carefully.

The purpose of practicing in this environment is not to improve one's cultivation. Wang Lun wants to keep himself in a state of sufficient magic power at any time.

In a flash, Wang Lun observed for two hours.

In the past two hours, there were neither monsters nor monsters entering the main entrance of the main courtyard.

The monsters are generally larger in size. Even if they can only observe half of the main entrance, generally speaking, they can ensure that they will not be missed.

"It seems that the leader of the demon beast power, the long golden dragon, is still fighting with Yuan Feng."

If the fight ends, the golden dragon should enter the ancient building.

Wang Lun continued to observe. After only a few minutes this time, he heard a loud voice coming from the air outside.

"Yuan Feng, you are too useless. When you come to the territory of my monster power, you can't even hurt a single hair of my hair, hahaha!"

The voice was arrogant, exuding contempt for Yuan Feng.

Without analyzing, Wang Lun also knew that the sound could only be made by the Golden Dragon.

No one in Jin Long and Yuan Feng should be able to do anything to each other, and the battle will not determine the outcome.

This is also within Wang Lun's estimate. Which side really has the strength to kill the other side, and the other cultivator has long since disappeared.

Jinlong's voice fell, and Yuan Feng's voice immediately rang: "So what if you are in the core area? I come whenever I want to come. If I want to leave, I can leave at any time. Why don't you accept it? Jinlong, if you use some use, just use your strength to keep me."

Tit for tat.

However, the two middle-level cultivators in the Nascent Soul Realm did not continue to talk. After Yuan Feng finished speaking, there was no movement outside.

More than ten minutes passed, and Wang Lun saw the gate of the main courtyard slowly opening, followed by a golden dragon quickly passing through.

Then, the door closed again.

In the short time when the door opened, Wang Lun only saw that the main courtyard was about the shape of a courtyard. Because the perspective was limited, he could not see more interior layouts.

After recording the time when Jinlong entered, Wang Lun waited.

There is no need to guess now. The monster team went out to hunt wild animals. What the beasts did after they were brought into the ancient building must be related to the snake demon skeleton buried underground.

The snake demon has heavy yin energy. If we bury the snake demon with extremely heavy yin energy into the ground from the perspective of suppression, the Yin evil produced will make a place become Yin evil.

But after Fairy Tianfeng built her residence, she suppressed the snake demon skeleton underground. She did not have to do anything when she was full, but needed to take advantage of a certain characteristic of the snake demon skeleton.

If you believe that it is the use of the yin energy of the snake demon, then the place in the main courtyard is a place with an abnormal fire.

The yang fire was raging, affecting the main courtyard, and the snake demon bones were needed to regulate yin and yang and maintain balance.

"This is just my speculation from one aspect. What's going on, and I have to investigate it on the spot."

Wang Lun next thought about what the monsters were doing.

The monsters may want to use some method to collect the energy that has been integrated into ancient buildings for ten thousand years through snake and demon bones?

Or is it that you want to control the skeleton of the snake demon, for example, refining the snake demon into a yin object?

Wang Lun tends to be the second speculation.

Because for the monsters, the total amount of energy in the ancient buildings is also very small, and Wang Lun could not have imagined that the monsters would use these energy.

For example, if he hadn't been able to absorb such high-level energy without the Ten Thousand Spirit Treasure Vase, he would have no use to hold it himself and would not have been useful.

If it is used directly, in fact, the mana consumed in the acquisition process alone will be much more. Eliminating these losses, there is not much energy that can be used, and monsters are unlikely to do such thankless things.

The second speculation is much more likely.

Of course, Wang Lun knew that he had to go to the underground of the main courtyard in person.

After Jinlong left, Wang Lun continued to observe for two hours.

During the process, Jinlong did not enter the ancient building again.

This represents a lot of meaning.

"As the strongest monster, the Golden Dragon is not in charge of ancient buildings, which shows that the things the monsters do in ancient buildings do not need the Golden Dragon to dominate."

"Secondly, it also shows that Jinlong is very at ease with the defense in the ancient buildings."

Wang Lun was naturally happy to see this situation.

He wants to enter the main courtyard, the premise is to avoid encountering powerful people like Jinlong, who are in the middle stage of the Nascent Soul Realm.

Wang Lun continued to calculate the time and waited for more than five hours before the golden dragon finally appeared and entered the ancient building.

The last time I left, and now I have been in, there have been almost eight hours apart!

Moreover, Jin Long stayed in the main courtyard for less than twenty minutes and left again.

After observing this, Wang Lun was very convinced that the ancient building was not the residence of the Golden Dragon, nor was it a place for cultivation. The Golden Dragon would not appear here for most of the day.

As for other monsters, there were very few situations in and out. During these eight hours, Wang Lun only saw a few teams of monsters appear outside the gate of the main courtyard with ordinary beasts they were hunting.

But the monster team could not enter.

After getting outside, the monster team will send a signal, and then a special white bear monster will come out to take away the ordinary beasts they are hunting.

The monsters in the ancient buildings are almost fixed, and it is not known how many monsters are inside.

"The main courtyard is independent and the environment is relatively closed. The monsters inside are only busy with their own affairs. In addition, they think that the environment is safe and their alertness should not be very strong. If I sneak in, be careful and I should be able to detect some things."
