Tate no Yuusha no Nariagari - Chapter 309 - Straying Off Course

Lin Yuan took a ‘Gate to All Realms’ and traveled to the vast universe of the Star Sea.

The most powerful person here can destroy the starry river system with a snap of his finger, and tens of millions of light years are coming in a blink of an eye.

Lin Yuan, who has been reduced to the bottom, can only rely on the ‘Gate of All Realms’ and the bound talent ‘Heaven-defying Comprehension’ to travel through all realms and become stronger silently.

[You have incredible understanding, practice the Yi Jin Jing, and understand the ‘Yi Jin Jing, body exchanging blood and quenching the gods’]

[Your understanding is against the heavens, you understand the thunder in your palm, and understand the ‘Thunder Creation and Development Method’]

[Your understanding is contrary to heaven, watching the birth and death of the world, and realizing the ‘world in the palm of your hand’]

[Your understanding is contrary to the heavens, you have studied the art of incarnation outside the body, and realized the ‘Great Law of Self-Transformation’]

…

As he traveled back and forth again and again, Lin Yuan grew stronger endlessly, until… he was invincible in the world.
