I can communicate with mythical beasts!

Liu Feiyang and the ancient thunder dragon looked at each other. This pattern was indeed strange. It was this pattern that was constantly absorbing the ancient thunder dragon's spiritual power, causing it to become extremely weak.

"Senior, what is the origin of this pattern? I only know that the spear is not very powerful in that person's hand, but the power of the seal is very strong."

The ancient thunder dragon stepped forward and asked.

"Haha, this only shows that the person who attacked you has not yet mastered the true power of this pattern. I have truly experienced it myself. The owner of this pattern can wipe out all the vitality of the world with just a wave of his hand, leaving no grass behind."

The Medicine Emperor snorted coldly, as if he was remembering the great battle that year.

As soon as these words were spoken, Taikoo Thunder Dragon and Liu Feiyang all took a deep breath. The strongest opponent they had seen so far was the half-step wild beast Ghost-faced Whale. However, they asked themselves, the Ghost-faced Whale did not have the ability to directly wipe out all living beings.

"We originally thought that we had sealed that guy away forever, but we didn't expect to encounter him again in this way. It seems that the world is about to face another great disaster."

The Medicine Emperor sighed lightly and returned the silver needle in his hand to Liu Feiyang.

But Liu Feiyang held these silver needles as if they were holding a pile of hot potatoes.

"Senior, please tell me the origin of this pattern."

The ancient thunder dragon asked.

"…The story began tens of thousands of years ago. At that time, there were five Spiritual Emperors on the entire continent, which are now known as the Five Ancient Emperors. The five of us restrained each other, which allowed the continent to enter a long period of peace."

The Medicine Emperor sat cross-legged, and the spiritual power in his hand turned into a cloud of mist. Then five little figures stood in the shape of a five-pointed star and floated above a dusty map under his feet. Each of these five figures had a small crown.

"But soon, this peace was broken. A dimensional crack suddenly appeared, and a large number of void monsters poured out of it, slaughtering the Holy Spirit wantonly. The Medicine Emperor of your beast tribe took the lead and led 9981 powerful wild beasts to launch a counter-encirclement and suppression against these void monsters."

Having said that, the Medicine Emperor looked towards the Ancient Thunder Dragon, and his words revealed his respect and admiration for the Demon Emperor.

"Who summoned this interdimensional rift?"

The ancient thunder dragon asked.

"I don't know, and no one knows. This matter has remained a mystery until now. After the Demon Emperor set an example, the other four emperors led their own forces to counterattack. Victory reports came from various battlefields until we attacked the entrance to the rift in the other dimension..."

Having said this, Yaodi's expression became even more serious.

"Did you destroy the rift?"

Liu Feiyang asked.

"not at all."

Yao Di shook his head and looked at the five little men standing in a row in front of him.

"Could it be that even the combined efforts of the five Spiritual Emperors were unable to destroy that Forgiveness Crack?"

Liu Feiyang was a little shocked. The combined power of the five Spirit Emperors was enough to sweep across the entire continent, but they were unable to destroy a small crack.

"It's not because we are not strong enough, but because the master of these void monsters has come out. That man calls himself the Demon Emperor. The five of us together are no match for him. In the end, the Demon Emperor, the Human Emperor, and the Dao Emperor burned their souls and exploded before they could barely seal him back into the dimensional rift."

The Medicine Emperor waved his hand gently, and the misty figure in front of him slowly dissipated.

After hearing this story, Liu Feiyang and Taikoo Leilong's outlook on life was overturned. They did not expect that such a horrifying incident would happen on the continent ten thousand years ago.

"Could this pattern be..."

Liu Feiyang looked at the silver needle in his hand with some shock and had already guessed what it was.

"Yes, the pattern on it comes from the Demon Lord, and this spear also came from his hand."

The Medicine Emperor nodded. Although he was extremely reluctant to see this happen, the traces of the Demon Lord did reappear on the continent.

"What should we do? Is there anyone who can be a match for the Demon Lord now?"

Liu Feiyang asked in a panic.

"Don't panic. If the Demon Lord has reappeared, how could he not continue to cause chaos in the world? This proves that he has not completely escaped from the seal. You young people still have time to grow up."

Yao Di placed his hand gently on Liu Feiyang's shoulder, his eyes full of hope.

The failure of the Five Ancient Emperors was partly due to their unfamiliarity with the Demon Lord. Now, if the Demon Lord escapes, their strength will inevitably be greatly reduced, and they may not be unable to defeat him.

"Senior, may I ask where the Demon Emperor of our clan is buried..."

The ancient thunder dragon asked with some sadness.

"I don't know about that. The three emperors burned their souls and can no longer enter the cycle of reincarnation. Even if I use the dead tree to revive, it can only make them live ten more years. As for where their descendants will bury them after ten years, only they themselves know."

The Medicine Emperor shook his head helplessly. The Great Emperor had fallen, and even as the Medicine Emperor he could do nothing to stop it.

"Okay, thank you, senior..."

The ancient thunder dragon bowed and already had his own ideas in mind.

"As for you, kid, I originally planned to let you master all of my knowledge step by step. Now it seems that time is obviously not enough. You need to grow up as quickly as possible."

Yaodi thought about it and decided to start the hellish training for Liu Feiyang.

Liu Feiyang seemed to understand the seriousness of the matter. He no longer disliked the boring training and nodded vigorously.

In the following time, the two people in the Tomb of the Medicine Emperor began to practice madly. During the waking hours, Liu Feiyang continued to practice different acupuncture methods, medical skills, and study pill recipes. Even when he fell asleep, he would be soaked in a large medicine barrel.

According to Medicine Emperor, even if you are a doctor, you must have enough strength to protect yourself. Only by taking your life into your own hands can you be safest.

And Liu Feiyang doesn't have to worry about the side effects of forcibly improving his strength through drugs. After all, his master is the strongest doctor in history—the Emperor of Medicine.

Three months passed in a flash, and when Liu Feiyang woke up from the medicine barrel for the last time, the Medicine Emperor was already standing in front of him.

"The three months are up. You said before that you had things to do. I don't care about that, but you must never forget the mission you are carrying."

Yao Di handed Liu Feiyang an exquisite wooden token and gave him instructions.

Liu Feiyang took the token and found that although it was made of wood, its weight was no less than a piece of pure iron. There was also an antique word "medicine" engraved on it.

"This token symbolizes your status as a teacher. With the token, you are the Medicine Emperor's only disciple."
