MTL - A War Between Spies - Chapter 1421 Where is wrong?

“Kill Hamyuts Meseta”

A story about a world where all dead people become “Books” and are housed in a Library. The boy named Colio Tonies had his memories taken and a bomb transplanted in his chest. His life’s purpose is killing the world’s strongest Armed Librarian, Hamyuts Meseta. But, one day he gets his hands on the “Book” of a beautiful princess and falls in love at first sight. Furthermore, that love will cause Colio to get involved in a grand scale battle…

Karsha, a general in the United States Army, was a loving father and husband who was accused of killing his wife and two children. As a result, he was sentenced to death. However, his life took a turn when a sinister being transmigrated his soul to a world of cultivation. He awakened as a slave and slowly rose through the ranks thanks to a strange system with its own agenda. He began walking the path of cultivation and immortality, which will soon drive him into a conspiracy so grand that his understanding of who he was, who he is, and who he is to become will be put into question.

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

A tree of 10,000 flowers, the world is the door.
The spells change a lot, but the hearts of the people are unchanged.
