Undead buff: I am really invincible

"Hello, classmates, don't worry about me, I'm here to see Lin Feng."

Shangguanji smiled and greeted everyone, and then looked at Lin Feng eagerly.

"Lin Feng, where's the golden crystal core you mentioned?" Shangguanji's tone was very urgent.

"Here, here you go." Lin Feng casually took out the golden crystal core from the space ring and threw it to Shangguan Ji.

Shangguanji carefully took the golden crystal core and looked at it carefully.

"Lin Feng, give me a room and come in." Shangguan Ji's face was serious.

Upon seeing this, Fatty found a room with Lin Feng and Shangguan Ji.

After finding the room, Fatty was about to leave, but Lin Feng stopped him.

Fat people are one of our own, there is no need to avoid fat people.

Shangguan Ji glanced at Fatty, said nothing, and continued to look at the golden crystal core in his hand.

Ten minutes later, Shangguanji exhaled and looked away.

"Lin Feng, I didn't expect you to be so lucky. It's really a heavenly crystal." Shangguanji said with emotion.

"Teacher Shangguan, what is this sky crystal?" Lin Feng asked. Lin Feng had never heard of this sky crystal.

"This sky crystal is a precious treasure."

After Shangguan Ji's introduction, Lin Feng finally knew what the Sky Crystal was.

Sky crystal is actually just a crystal nucleus.

It's just that this kind of crystal nucleus can only be mutated from the crystal nuclei of direct members of the alien beast royal family.

Not all direct descendants of the royal family of alien beasts can mutate into sky crystals. Only one of the hundreds of direct descendants of the royal family may appear.

And every royal family that has a sky crystal stone is a genius among alien beasts, equivalent to the supreme spiritual body of the human race.

The reason why sky crystals are precious is because if human beings absorb sky crystals, their spiritual bodies can directly evolve into supreme spiritual bodies.

Moreover, the evolved supreme spiritual body is a mutated supreme spiritual body, which is more powerful than the ordinary supreme spiritual body.

Because of this, the sky crystal can be said to be a super precious treasure, so Shangguan Ji is so excited.

[To be honest, I have been reading books recently to catch up on updates. I can switch sources and read aloud with many sounds. It can be used on both Android and Apple. 】

Everyone on the upper level of the human race knows about the existence of sky crystals, but it is basically impossible to rely on sky crystals to evolve a supreme spiritual body.

Because sky crystals are basically impossible to appear in the human world.

The direct members of the ten royal families of alien beasts all live next to the king of alien beasts.

Wanting to kill a direct descendant of a demigod next to him is basically no different from seeking death.

Lin Feng was also very lucky. The third prince just came to the human world and was killed by Lin Feng.

And the most coincidental thing is that the third prince happens to have a sky crystal in his body.

After talking about how precious the sky crystal was, Shangguanji told Lin Feng not to leak the news about the sky crystal.

Otherwise, I am afraid that I will receive coveted eyes.

When the time comes, even the powerful ones at the Tiangang stage will shamelessly snatch the sky crystal.

"Lin Feng, remember, you must hide it well and don't let others find it." Shangguan Ji repeatedly warned Lin Feng.

At this time, Lin Feng suddenly asked: "Teacher Shangguan, can anyone take this heavenly crystal stone?"

After hearing Lin Feng's words, Shangguan Ji nodded subconsciously and said: "It is true that anyone can take the Sky Crystal Stone, and it is best used by warriors who have not yet broken through to the stage of transformation.

Warriors who have not broken through to the mortal transformation stage use sky crystals. Not only can they evolve their spiritual bodies into supreme spiritual bodies, but they can also open all the acupoints through the power of sky crystals. "
