One attribute point per second, I am invincible!

"They have gone in, but they are not disciples of Wandao Academy. They only have a general understanding, but not a deep understanding!"

"According to what they said, the secret here has something to do with Wandao Academy, and they don't want to get involved!"

Wang Nian'an sighed, the Spiritual Clan's Reincarnation Realm and the Wuji Empire's Reincarnation Realm both said this.

It seems that the secrets involved in the cabin are dangerous and they are not willing to take the risk.

Moreover, if you don’t reach the realm of reincarnation, you don’t even have the qualifications to know this secret.

"Lin Mu, after entering, if the things involved are too dangerous, don't be reckless!"

"This secret is actually no longer important to Wandao Academy!"

Wang Nian'an sighed, 1.3 billion years have passed, and it no longer matters what the secret is.

However, there is only one Lin Mu, and the wishes of several deans of Wandao Academy over the past 1.3 billion years have come true.

He didn't want Lin Mu to get involved in danger for that illusory secret.

"Teacher, don't worry!"

Lin Mu nodded cautiously to Wang Nian'an. Wandao Academy involves Xuanhuang Palace, and Xuanhuang Palace involves the entire universe.

After returning from Zhengqing, he knew that the secret of Wandao Academy was not simple.

He came to the wooden house and put his hands on the wooden door.

A force came from the wooden door and circled in his soul space.

Not feeling any harm from this power, Lin Mu ignored it.

He knew that this was a way for the wooden house to test his realm.

"Click!"

There was a soft sound, and the wooden door slowly opened.

A white barrier appeared behind the wooden door, blocking Lin Mu's view.

"Not only are there means of detection, but there are also barriers to stop it!"

Lin Mu took one look at the white barrier and instantly understood its function.

He mobilized the soul power in his true self, and a hole wide enough for one person slowly appeared in the barrier.

This barrier is to prevent someone from following him in, and to prevent low-level people from entering the wooden house.

After stepping into the barrier, the barrier returned to its original state and the wooden door slowly closed.

Wang Nian'an looked at the closed wooden door and murmured: "Teacher, what is the secret inside this wooden house?"

He told Lin Mu to be careful, but actually he still wanted to know what secrets the first dean left behind.

His teacher mysteriously disappeared after entering the cabin.

Lin Mu looked around inside the wooden house. The furnishings inside were very simple.

A wooden table, a futon, and a portrait.

The portrait shows an old man with white hair and beard standing in a green grassland.

The moment he stepped into the wooden house, the portrait began to change.

On the portrait, a dark vortex slowly appeared, and finally settled on the portrait.

"Time and space channel?"

Lin Mu looked at the vortex and could tell what the vortex was just at a glance.

Within the vortex, a strong force of time and space is spreading outward.

He squinted his eyes and looked at the portrait. There was actually a space inside the portrait!

However, there is a layer of restrictions on the portrait that blocks his vitality detection.

He couldn't see what the inside of the portrait looked like. He could only feel that the space inside the portrait was not very large.

And this vortex is the entrance to the inner space of the portrait.

Lin Mu pursed his lips and stepped into the vortex.

Since the two elders of the Eastern Alliance have entered this wooden house, it proves that the inside of the portrait should be safe.

When he opened his eyes, he saw a blue sky and white clouds in front of him, and Lin Mu was standing on the soft grass.

The space here is really not big, only the size of a football field.

There was a big tree not far from him. Under the big tree, sitting cross-legged, was the old man in the portrait.

"come on!"

Feeling Lin Mu's arrival, the old man with his back to Lin Mu spoke slowly.

Lin Mu teleported directly to the old man.

"Junior Lin Mu, I have met my senior!"

He bowed his hands in salute, took a closer look at the old man, and found that the old man was not in a physical state, but in an energy state.

"Are you a disciple of Wandao Academy?"

The old man slowly opened his eyes and looked at Lin Mu.

"Yes!"

Lin Mu nodded. There was nothing to deny. He came here just for the secret of Wandao Academy.

"It has been 1.3 billion years, and you are the second disciple of Wandao Academy to come here!"

"Let me introduce myself. My name is Li Wandao, and I am the first dean of Wandao College!"

The old man sighed, obviously a little disappointed with the performance of Wandao Academy over the years.

In 1.3 billion years, only two people in the reincarnation realm were cultivated!

In fact, Lin Mu knew who this old man was before he came in. Zhengqing had already told him.

And what’s in this portrait space should be Li Wandao’s true self.

"Disciple Lin Mu, pay homage to the Patriarch!"

Now that Li Wandao has revealed his identity, the due etiquette is still indispensable.

At first Li Wandao did not explain his identity, he could only call him senior.

Now that Li Wandao has revealed his identity, he will be called the Patriarch!

"There's something I don't know about my disciple. Why can't I know the secret you left behind if I'm not a disciple of Wandao Academy?"

Lin Mu did not go straight to the topic, but asked the doubts in his heart.

"I never said that only disciples of Wandao Academy can know this secret!"

"It's just that they are not willing to take this risk!"

"The same goes for the disciples of Wandao Academy. They don't want to take risks, and I won't force them!"

Li Wandao said slowly, a total of three people have come over the years, including Lin Mu, four.

Two students who were not disciples of Wandao Academy chose to quit immediately after learning about the risks.

There was also a disciple of Wandao Academy, and he was the only one who chose to take the risk and learn this secret.

Maybe it’s because of spreading rumors like this!

Hearing this, Lin Mu reacted. The teacher also told him that the reincarnation state could know this secret.

It did not say that only disciples of Wandao Academy could know this secret.

And this secret is related to Wandao Academy, and it seems that it came from the mouths of two reincarnation realms in the Eastern Alliance.

"What exactly is this secret?"

Lin Mu asked, the more this happened, the stronger the curiosity in his heart.

What kind of risk caused the two elders of the Eastern League to give up?

"Before knowing this secret, there is something I must tell you!"

"You say!"

Lin Mu knew that the prerequisite for discovering the secret was here!

"You must swear with your soul that after knowing the secret, you must go to the primitive continent within a hundred years!"

Li Wandao said slowly. After speaking, he looked at Lin Mu calmly, waiting for Lin Mu's response.

"Soul swear, primitive continent?"

After hearing this, Lin Mu frowned.

He had heard about the primitive continent from Xuanyou and Zhengqing. This place should involve some secrets of the universe.
