Cultivation by Trial and Error - Chapter 24 - Leech VS Toad

Reborn into the world of Yugioh, it's natural if my goal is to become the best duelist!

Feng Xia transmigrated to a fantasy world. This was the era when spiritual auras were exhausted, various scriptures were lost, and all cultivation techniques failed to aid the cultivators in improving. Feng Xia discovered that he had a superpower of attributes, but something seemed off.

He killed a Black Jade Spider by stepping on it. [Spider Maiden x1] dropped.

He defeated a strong opponent that qualified as a Great Emperor. [Teenage Great Emperor x1] dropped.

He was in a fight with a goddess for three days and three nights. [Mysterious Young Girl x1] dropped.

“Daddy,” a young girl greeted him in a sweet voice. Feng Xia was struck dumb.

On modern-day Earth, An Lin seems to have been abandoned by God.
When his father suddenly disappears, An Lin is left with his father’s immense debt, putting his life at risk.
After being forced to a rooftop by his pursuing creditors, An Lin is unexpectedly swept off his feet and brought to the ground safely.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.
