MTL - Marvel: Containment Foundation From Scratch - Chapter 101

The Heavenly Voice was bestowed upon the world, and so the calendar of the Great Dao began. The world entered a new age of digitized cultivation. Humanity activated the immortal destiny seal to become cultivators.

The story is about a boy entering high school, who answers a strange call from a public phone one night.

And with this, a very strange summer begins.
