Douluo Dalu - The Strongest God

Then they met the academy's guard.

"This Grandmaster wants to be a teacher here," A City Wall Guard said.

Ryu shows his registration card and his recommendation letter. When they saw this, "Oh… please follow me, Grandmaster"

Then Ryu followed him and met the board of Education. He met 3 peoples, one principal and two vice principal, each of them was a Spirit Douluo (rank 80 spirit master)

"I'm Yao Lao. Greet to Principal and Vice Principals" then Ryu kneeled.

"Stand up. What's the matter?"

"I want to apply here as a teacher" then Ryu show his registration card and his recommendation letter.

"Although you have a recommendation from Spirit Hall, you must have the ability to be a teacher here...." one of vice principal said

Then Ryu shows them his Spirit Rings: 7 Black Rings appeared.

"What?"

"Rank 75 Spirit Master"

"Moreover, all of his spirit rings were black"

"He isn't ordinary Spirit Master"

"He got Spirit Hall Recommendation too"

There is an optimal age of Spirit Ring for every bottleneck that identifies the oldest possible Spirit Ring that can be absorbed without significant risks. Spirit Master can naturally absorb younger Spirit Ring, but the absorption of an older Spirit Ring can result in heavy injuries or even in death upon rejection.

However, there have been a rare few cases of Spirit Masters who successfully absorbed Spirit Rings beyond the optimal age.

Usually Spirit Master could only absorb 10.000 years old spirit beast for his 5th spirit ring. If they absorb 10.000 years old spirit beast for his 1st until 4th spirit rings, they would get a soul shock.

Soul shock is a special ability that arises when a spirit beast older than 10,000 years is dead, but its soul is yet to be dissipated. If your mind is not matured and cannot decrease the soul shock from the ring, you will become mentally retarded and have the mental capacity of a 2-year-old.

Of course, Ryu had 2 Golden, 1 Red, and 4 Black Spirit Rings. He used Genjutsu to make all of them black.

"Although you are rank 75 Spirit Master, you must show us how powerful you are. Now .... " before the principal finished, Ryu used Soru and appeared behind the principal, and put his katana on the principal neck.

"Too fast"

The three of them were shocked. If this was a true battle, they would die in a second, they were defenseless without summoning their martial spirits.

"Am I accepted"

"Yes"

"Start from now, Yao Lao is a teacher in the Star Luo Imperial Academy"

Then they told him about the academy.
