"Uh! Diesel! What is your relationship with the Immortal Emperor of Firewood?" Xu Yuntian looked at the skeleton and said in surprise.

"Hey! I am the brother of Chaihuo Immortal Emperor! I was killed by him..." the skeleton sighed.

"What! You are the brother of Chaihuo Immortal Emperor! Why did he kill you?" Xu Yuntian said in shock.

"Hey! It's been a long story. It's been more than eight thousand years. Chaihuowang and I are both in the realm of the Golden Immortal. In the same palace, we found the note left by the Immortal Emperor and a jade box."

"That note is the cultivation experience and secret technique left by the Immortal Emperor. Inside the jade box is an Emperor's Realm crystal. In order to get the note and the Emperor's Realm crystal, Chai Huowang used despicable means to drug me..."

"When I woke up, I was tied up now. Chai Huowang forced me to hand over the letter and the Emperor Realm Crystal. He used all kinds of despicable means to hand over the Emperor Realm Crystal."

"Then Chai Huowang forced me to hand over the note again. I didn't give it to him. He locked me in the heavy magnetic water prison and tortured me. I never handed it to him."

"In the end, I was tortured by him and almost died. When I was dying, I used the secret technique in the note, leaving a trace of residual soul, waiting for the destined person..." Chai You said.

"Wow! It turns out that the Chaihuo Immortal Emperor is such a despicable and shameless person! He actually killed his own brother!" Xu Yuntian said in shock.

"Yes! Chai Huowang is despicable and shameless, he is simply not a human..." Chai You cursed.

"Uh! What is that Emperor Realm Crystal Stone?" Xu Yuntian said curiously.

"The Emperor's Realm Crystal is the cultivation crystal left by the Immortal Emperor after his death. It is the crystal of his understanding of the Immortal Emperor. As long as he absorbs the Emperor's crystal, he can become the Immortal Emperor. Chai Huowang becomes the Immortal Emperor by relying on the Emperor's Realm Crystal. Otherwise, with his qualifications, he will never be able to become the Immortal Emperor in his life!" Chai You said.

"Oh! Where is that letter? Are you hiding it?" Xu Yuntian looked at the skeleton and said.

"Yes, I hid my note in the space. I'll give you the note now!" Chai You said.

"Oh! You give me the letter, what are the conditions?" Xu Yuntian looked at the skeleton and said.

"That's right! There is no free lunch in the world. You must promise me, avenge me, and kill Chaihuowang!" Chai You said viciously.

Xu Yuntian nodded and said, "Okay, this is fine. Even if you don't ask me, I will kill the Chaihuo Immortal Emperor. I have a grudge with him!"

"Hey! Boy! Just based on your current realm, it may take tens of thousands of years to kill Chaihuowang! It is not easy to become an Immortal Emperor!"

"However, there is a way to achieve the Immortal Emperor in the letter, that is, find the Emperor's Realm crystal and absorb the Emperor's Realm crystal, and you will soon become the Immortal Emperor. At that time, you will find Chai Huowong to avenge you, which will be much easier." Chai You said.

"Are there many crystal stones in the Immortal Realm? " Xu Yuntiandao.

"There are very few crystals in the Immortal Realm. Only when the person who achieves the Immortal Emperor dies will the Immortal Realm crystals be left behind. The Immortal Emperor's lifespan is very long. He will not die unless he is killed by someone."

"Therefore, the crystals in the Emperor Realm are very rare, and there will be no more than five in the entire Immortal World. The crystals in the Emperor Realm are very precious, otherwise there would be so few immortal emperors in the Immortal World! Because it is very difficult to become an Immortal Emperor." Chai You said.

After Chai Hao finished speaking, his skeleton arm moved, the space trembled, and a purple jade appeared on the skeleton's palm.

The purple jade slowly flew up and flew to Xu Yuntian, who grabbed the purple jade.

The purple jade disappeared into the palm of his hand, and the content of the note appeared in Xu Yuntian's mind. Seeing the content, Xu Yuntian showed shock.

This note was actually a note left by Emperor Yu. Xu Yuntian learned about Emperor Yu’s deeds from the memory of the celestial immortal Sun Haoyun.

Emperor Yu was the greatest immortal emperor in the ancient times of the immortal world and the most powerful immortal emperor in the immortal world. He once unified the immortal world, but later he didn't know what happened, Emperor Yu disappeared.

Some people say that Emperor Yu was killed by someone, while others say that Emperor Yu left the immortal world and went to practice in order to achieve the immortal ancestor.

These are all legends. No one knows what happened to the Yudi.

"Oh! This is the letter from Emperor Yu!" Xu Yuntian said in surprise.

He was shocked when he saw the content of the note. The note recorded many top immortal arts and secret cultivation techniques of the soul.

"Yes, this is the handwritten note of Emperor Yu, which is even more precious than the Emperor's Realm crystal stone, because many of the various immortal techniques, formations, weapon refining and other people recorded here are lost secret techniques."

"I forced me to hand over the letter and the Emperor Realm Crystal Stone back then. I handed over the letter first because this letter is more precious than the Emperor Realm Crystal Stone. Unfortunately, I didn't have time to practice at that time, otherwise I wouldn't have been harmed by the Crystal Stone back then." Chai You said.

"Diesel! Don't worry, I will avenge you!" Xu Yuntian looked at the skeleton and said.

"Well! I hope you have a chance to avenge me! Okay, my remnant soul is about to dissipate..." After the skeleton finished speaking, his arms dropped and his open mouth closed.

"Senior Chai You! Senior Chai You..." Xu Yuntian shouted a few times, but did not respond. He knew that Chai You's remnant soul had really dissipated.

Looking at Chai You's skeleton, he swears: "Senior Chai You! Rest in peace, I will definitely avenge you and kill Chaihuo Immortal Emperor!"

Then Xu Yuntian sat down and read the note left by Emperor Yu. He saw a secret technique for the cultivation of the soul and said in surprise: "Wow! This secret technique for the cultivation of the soul is actually a secret technique for improving mental power!"

"As long as I increase my mental power to the early stage of the Heavenly Level, I will be able to refine the intermediate Immortal Destroyer and kill the Golden Immortal in seconds!" Xu Yuntian said excitedly.

He immediately began to practice the secret technique of the soul cultivation. The secret technique of the soul cultivation of the Yudi Emperor was different. His principle was to improve the ability of the soul, so that the soul could leave the body and absorb the energy from the void.

Therefore, Xu Yuntian's little saint left his body and sat cross-legged on his head to absorb the energy from the void.

About an hour later, the little saint Xu Yuntian's soul changed. The little saint became much bigger and transparent, just like a little glass man.

"Uh! If you want to improve your mental power to the middle stage of the Heavenly Level, it will not work for a short period of time! It's better to find a way to leave the Heavy Magnetic Water Prison! Otherwise, you will be killed by the Chaihuo Immortal Emperor sooner or later!" Xu Yuntian stood up.

To leave the Heavy Magnetic Water Prison, the formation must be broken. Xu Yuntian began to study the experience of the formation left by Emperor Yu. About an hour later, he finally found a way to break the Heavy Magnetic Water Prison Formation.

The formation on the wall of the heavy magnet water prison is the eight-star cage formation, which is an intermediate formation. The solution is very simple. You must find the array eye stone and break the array eye stone. The eight-star cage formation will be cracked.

"Where is the array eye stone of the Eight-Star Cage Formation?" Xu Yuntian glanced around the Chongmagnetic Water Prison to look for the array eye.

According to the Yu Emperor's experience of formation, the array eye stones of the eight-star cage formation are generally in the northwest direction. After Xu Yuntian determined the direction, he walked towards a tall stone pillar.
