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

"What is a snake molt?" asked Apricot curiously, "I know almost all these things I perceive, but I don't know this." ”

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

When I lived here with the Heavenly Phoenix Fairy, after all, it was 10,000 years ago, and many things I might have "seen" before, but now I really don't have an impression.

"Snakes," Wang Lun explained, "many kinds of snakes will molt, they crawl on the ground, the surface skin is smooth and tough, can ensure that the flesh and blood are not hurt when rubbing against the ground, you can understand the snake skin as the fish scales on the fish, the fish scales do not need to be replaced, but the snake skin rubs against the ground for a long time, it will gradually age, and the snake also needs to put on a new skin, so the old skin will fade, and the skin taken off is the snake molt." ”

I hesitated before, because I felt that this golden, snake-like thing could be understood as both a snake and the skin of a strange insect. Of course, Wang Lun felt that it was more likely that the snake had molted.

"It turned out to be the skin of a snake. Apricot said she understood.

After she finished saying this, she directly cut off her voice, and it took two seconds before the voice appeared in Wang Lun's mind again, and it became an explosion.

"Wang Lun, I remember!"

Little Apricot shouted.

Wang Lun hurriedly asked the other party with consciousness: "Little apricot, what do you remember?"

He expected the machine spirit to remember how to use the energy here.

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

"The bones of the snake demon are buried in the ground of the residence?" Wang Lun immediately asked, "The Heavenly Phoenix Fairy is doing this, is it to use the bones of the snake demon to suppress something?

Apricot shook her head and said she didn't know.

She just happened to hear Wang Lun's explanation of the snake molt, and repeatedly mentioned the snake in her words, so she suddenly felt blessed in her heart, thought of the snake demon, and remembered the memories of 10,000 years ago.

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

On that day, the Heavenly Phoenix Fairy left the Wanling Treasure Vase at the beacon location in the lake, and the Heavenly Phoenix Fairy herself went out, and the machine spirit did not know what the master had experienced, but only that it was very late that day, the master came back, left the beacon location with the Wanling Treasure Bottle, and returned to the residence.

Then, with divine sense, the machine spirit sensed and "saw" that the Heavenly Phoenix Fairy shook a storage ring and shook the corpse of a big snake to the ground.

The snake demon was about two hundred meters long, curled up in a ball, forcibly squeezed together by the owner, stuffed into the storage ring, and after landing, the owner straightened the snake demon's body, and then used mana to remove the flesh and blood of the snake demon, revealing the complete skeleton of the snake demon.

After that, the owner dug a passage about the size of the snake demon in the underground of the residence, about square in shape, running through the entire courtyard of the main courtyard, and then buried the bones of the snake demon in the passage.

Because the machine spirit has a natural aversion to snakes, he did not ask his master why he buried the bones of the snake demon in the ground of his residence.

After listening to Xiao Xingzi's story, Wang Lun didn't know anything else, but one thing was certain: Tianfeng Fairy would not casually do things without a purpose.

At this moment, Wang Lun did not continue to use the Ten Thousand Souls Treasure Bottle to absorb the energy contained in the items in the room, but inspected the position of the back window of the three utility rooms and selected the most suitable place to observe the main courtyard.

The location of the utility room, diagonally behind the main courtyard, in the middle of the connection, is the pond and the pavilion.

Choose a location at the back of the utility room, and you can see about half of the front door of the main courtyard.

Wang Lun would not choose to leave the utility room and take the risk of observing outside, in order to gain the opportunity to fully monitor the main courtyard. If you do that, if you are discovered, your efforts will be lost.

Staying in the utility room, as long as he restricts his breath and uses mana in a small area, the utility room will be his natural shelter, which can facilitate his observation of the main courtyard.

Wang Lun found a table and transformed it, after sitting on it, he could see the outside without bending down, and his body could maintain a more comfortable posture.

Then, Wang Lun opened his eyes, observing and cultivating carefully.

The purpose of cultivating in this environment is not to improve cultivation, Wang Lun wants to keep himself in a state of sufficient mana at any time.

In a flash, Wang Lun observed for two hours.

In the past two hours, at the main gate of the main courtyard, neither the demon beast went out, nor did the demon beast enter.

The size of the demon beast is generally large, even if he can only observe half of the main entrance, in general, he can guarantee that he will not miss it.

"It seems that the alliance leader of the demon beast force, that golden dragon, is still fighting with Yuan Feng. ”

If the fight is over, the golden dragon should enter the ancient building.

Wang Lun continued to observe, and this time only a few minutes later, he heard a loud voice in the air outside.

"Yuan Feng, you are too useless, come to the territory of my demon beast forces, but you can't even hurt a single hair of mine, hahaha!"

The voice was arrogant, revealing contempt for Yuan Feng.

There was no need to analyze, Wang Lun also knew that the voice could only be made by the golden dragon.

Jin Long and Yuan Feng should be helpless against anyone, and they don't know whether they win or lose.

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

Jin Long's voice fell, and Yuan Feng's voice immediately sounded: "What if you are the core area here, I can come if I want, I can leave if I want, I can leave at any time, why don't you accept it, Jin Long, if you have some use, just use your strength to keep me." ”

-for-tat.

However, the two cultivators in the middle of the Yuan Infant Realm did not continue to fight, and after Yuan Feng finished speaking, there was no movement outside.

After another ten minutes, Wang Lun saw the gate of the main courtyard slowly open, followed by a golden dragon passing quickly.

Then the door closed again.

In the short time when the door opened, Wang Lun only saw that the inside of the main courtyard was roughly in the shape of a courtyard, and because the perspective was limited, he could not see more layout inside.

Noting down the time when the golden dragon entered, Wang Lun waited.

There is no need to guess now, the demon beast team went out to hunt the beast, and what the beast did after bringing it into the ancient building must be related to the bones of the snake demon buried in the ground.

The snake demon has a heavy yin qi, and if you bury the extremely yin snake demon into the ground from the perspective of suppression, the resulting yin evil will make a place become yin and evil.

But after the Heavenly Phoenix Fairy built a residence, he suppressed the snake demon bones under the residence, not because he was full and had nothing to do, but because he needed to rely on a certain feature of the snake demon bones.

If it is determined that it is with the help of the yin qi of the snake demon, then I am afraid that the place in the main courtyard is a place where the furnace fire is so strong that it is abnormal.

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

"This is just my speculation from one aspect, and I have to go to the field to find out how it is. ”

Wang Lun then thought about what the demon beasts were doing.

Maybe the monsters want to use the bones of the snake demon to collect the energy that has been integrated into the ancient building for 10,000 years in some way?

Or, do you want to control the bones of the snake demon, for example, refining the snake demon into a yin thing?

Wang Lun leaned towards the second speculation.

Because for the demon beasts, all the energy in the ancient building added up to the amount was very small, Wang Lun couldn't imagine that the demon beasts would have a place to use these energies.

For example, if it weren't for the Ten Thousand Spirits Treasure Bottle that could absorb this kind of high-grade energy, he would hold it himself, but it would be useless and useless.

If it is used directly, in fact, there is a lot of mana consumed in the process of obtaining it, and there is not much energy that can really be used to remove these losses, and it is unlikely that the monsters will do such a thankless task.

The second speculation is much more likely.

Of course, what is the specific, Wang Lun knows that he must go to the underground of the main courtyard in person.

After the golden dragon left, Wang Lun continued to observe for two hours.

In the process, the golden dragon did not enter the ancient building again.

There are many meanings for this.

"As the strongest demon beast, the golden dragon does not sit in the ancient building, which shows that the things that the demon beasts are engaged in in the ancient building do not need the golden dragon to lead. ”

Secondly, it also shows that Jinlong is very relieved about the defense inside the ancient building. ”

Wang Lun is naturally happy to see this situation.

The premise for him to enter the main courtyard is to avoid encountering a powerhouse in the middle of the Yuan Infant Realm, such as Jin Long.

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've gone in, and it's been almost eight hours in between!

Moreover, Jin Long only stayed in the main courtyard for less than twenty minutes before leaving again.

Observing this, Wang Lun was very sure that the ancient building was not the residence of the golden dragon, nor was it a place of cultivation, and the golden dragon would not appear here for most of the day.

As for the other demon beasts, there were very few cases of entering and leaving, and in the past eight hours, Wang Lun only saw a few groups of demon beast squads with the ordinary beasts they had hunted and killed appear outside the gate of the main courtyard.

But the monster team can't get inside.

After arriving outside, the monster team will send a signal, and then a special white bear demon will come out and be responsible for taking away those ordinary beasts that are hunted.

The demon beasts in the ancient building are almost fixed, and it is not known how many demon beasts there are.

"The main courtyard is independent, the environment is relatively closed, the demon beasts inside will only be busy with their own affairs, plus they think the environment is safe, the sense of vigilance should not be very strong, if I sneak in, be careful, I should be able to detect something. ”

Wang Lun didn't plan to wait any longer. With the help of Yuan Feng and the golden dragon fighting, he has successfully come to the utility room in the ancient building, and there is no condition to wait for a better opportunity to appear.
