MTL - Ninja School Teacher, I Can Become Stronger By Teaching - Chapter 52 There are also gaps between teachers (seeking further reading)

There are three realms in the multi verse; The Cosmic, the Mortal and the Nether realm.

Hal grew up in the mortal realm with no idea whatsoever of who his parents were.

His love for relics, adventure and the occasional danger would aid him in finding a genie's lamp.

Rubbing a genie's lamp should grant three wishes, but Hal is struck by lightening instead and eventually arrives in the Cosmic realm with a large book in his mind space titled; The Primordial Cosmic Grimiore, that apparently holds all knowledge for a perpetual reign.

And so Hal's journey begins in a little city called Salmon city, in the body of a 17 year old boy also named Hal but was sold into slavery by his own father.

Hal finds out who his mother (prior to reincarnation) whose bloodline now flows unmixed in his new body is....

Join Hal as he battles mortals, Dragons, phoenixes, Gods and many more together with his harem of Beauties for the complete subjugation of the three realms.

In a dilapidated temple, a young man receives an outdoor webcast system, and thus, his webcast journey begins. He easily finds lingzhi worth thousands of dollars, keeps a falcon as his pet, and displays skills that leave his audience in awe. When he turns his head around, he discovers that the whole world is watching him.

When he joins a show, everyone asks, “Is this webcaster cultivating to be a deity?”

Someone exclaims, “This isn’t an adventure, this is a vacation!”

A reporter asks him, “Your fans claim that you know martial arts. Is that true?”

He answers, “Not true.”

Yet, in the next moment, when a little red bird flies past him, he takes a leap from a tall platform before jumping down…

Known as the youngest academician-level senior engineer, Zhao Guoyang was reborn in the 1990s. In this era of economic globalization, with his extraordinary wisdom and extraordinary insights, he created one miracle after another and became a name that shocked the world!

Wisdom is condensed every bit, brilliance is created by sweat, and witness the rise of a great power!
