I Eat Tomatoes

In a world dotted with World Entrances to a demon world, demons have invaded humans for centuries. Humanity has united and one of the most ancient sects in the world, the Archean Mountain Sect, has set up an entire education system in the form of Dao Academies and defenses at the World Entrances.
Meng Chuan, a young genius, is an expert at the swift saber. Despite his noble heritage, he has one goal—kill all demons. Scarred by demons because of how his mother sacrificed her life for him, he strives to enter Archean Mountain Sect to get the best resources and training.
Other than cultivation, his only pleasure is drawing. And as he draws, he becomes stronger… 
Enjoy this blood-pumping piece of art in Meng Chuan's journey to slay demons with the help of united human comrades.

Archean Eon Art

How did he kill the demon commanders?

Meng Chuan's heart tightened. His grandaunt had long ordered him to keep the glabella space a secret until he had figured out what it was after entering Archean Mountain.

"Marquis," said Meng Chuan respectfully. "When I rushed to Blazing Sun Dao Academy, the demons had already attacked Blazing Sun Castle. Qiyue was also heavily injured. I was eager to save her, so I didn't think too much as I tried to stop the two demon commanders. I never expected my body to erupt with such extraordinary strength at that critical moment. The power of my saber arts also soared, and I managed to kill a demon commander with one slash. Following that, I killed the second demon commander."

"An eagerness to save Liu Qiyue?" Marquis Southcloud came to a realization. He nodded and smiled. "It looks like Liu Qiyue is very important to you. She managed to catalyze the eruption of your potential."
