The Black Beast’s Useless Concubine - Chapter 2500

Demons and Beast descended, terrorizing the whole world for the past hundred years. Everyone can awaken a grimoire and summon a beast during their age of ceremony. Lucas, awakening the weakest grimoire, also awakened the weakest beast- a small dog with no combat capabilities. Fortunately, as a transmigrator, Lucas also mysteriously awakened a system that allows him to evolve his summons into their mythical beast counterpart. Follow Lucas and his journey to greatness as he evolved his beasts into never been before seen mythical creatures.

Gu Yang crossed over to a high-martial world, eked out a living in small village for two years, and finally saved up enough and activated the Life Simulator system.

With a certain amount of money, a simulation can be run.

After the simulation ends, one of the three can be retained: realm, martial arts skills, or life wisdom.

[For five years you were an accountant, saved up enough money to buy a cultivation manual, practiced hard for ten years and became a Ninth Realm martial artist, but then ran into an enemy and died!]

[Once you left the mountains, you were at the Ninth Rank, became a protector of a certain family, practiced intensely for twenty years, broke through to the Eighth Grade, and ultimately, died of old age in a small town.]

[Once you left the mountains, you were at Eighth Grade, received recognition from a noble clan, were taught profound martial arts, but due to slow progress, were marginalized, and after a dozen years, you finally broke through to the seventh grade, but then encountered powerful foes on a mission and were killed.]

…

After countless rounds of simulations: [You encounter people, but none are a match for you. You realize that you have become invincible.]

The second day.

Xu Xing suspected that he had seen a pair of ‘gay’s. The left side of the boy’s body had two red strings. The one in front was tied to his hand, the one in the back was tied to the boy’s right side.

Xu Xing: Excuse me???
