He followed the apprentice to grind the medicine.

“Ding! 【Pharmacy】experience value +3!”

Master and brothers practice martial arts.

“Ding! You picked up a [Nursing Qi Gong Essence (White)], [Nursing Qi Gong] experience value +3!”

He killed the bandits, and actually picked up the opponent’s martial arts.

“Ding! 【Expression Concentration Skill】experience value +13!”

The master said that Qigong is not good at attacking and attacking, there is an upper limit of practice, and it can only prolong life.

But when Qin Huai picked up his experience and forcibly picked up Qi Yang Gong to the 50th floor, the qi in his body was like a real dragon, his pushing hands were like a stormy wave, and his offense and defense were integrated.

People in the world say that the two kinds of exercises are in conflict, and if you practice them forcibly, you will explode and die.

Qin Huai, who was able to gain experience, began to wander among the various forces.

He saw bones and raw flesh, living another life.

He saw the evil spirit cooking thousands of people, and his evil spirit was soaring.

He saw Buddha statues chanting scriptures in temples, and the Sanskrit sounds were like mantras.

Qin Huai picked up experience silently in order to survive in the troubled times.

- Description from novelbuddy

To reward Meng Fan for his bravery before his heroic death, the cosmos rewarded him with a ‘system’, sending him back in time to three months ago, alive.

Toradora!’s story begins with the male protagonist Ryuji Takasu who is frustrated at trying to look his best as he enters his second year of high school. Despite his gentle personality, his eyes make him look like an intimidating delinquent so he is utterly hopeless about his chances of getting a girlfriend anytime soon, and does not have many close friends either. After being greeted by his hungover mother in the morning, Ryuji goes to school and is happy to find that he gets to be in the same class as his best friend Yusaku Kitamura and crush Minori Kushieda. However, it is then that he unexpectedly knocks into “the school’s most dangerous animal of the highest risk level” — Taiga Aisaka — who just happens to also be in his class, and is a good friend of Minori.

Taiga has a negative attitude towards others and will not hesitate to snap at people. After meeting Ryuji, she takes an instant dislike of him. Taiga comes from a rich family, though she moved out to live on her own due to family issues, and by coincidence is now living in an apartment next door to Ryuji. After Ryuji discovers that Taiga has a crush on Yusaku, and Taiga finds out about Ryuji’s affections towards Minori, Ryuji suggests that they cooperate so they can win the object of their affections. Ryuji says he will do anything to get closer to Minori, which Taiga exploits, making Ryuji her personal servant, and getting him to do household chores like cooking and cleaning for her. Taiga spends a lot of her time over at his house, so much so that she could almost be considered a member of his family. Since Ryuji spends a lot of time with Taiga, he is opened up to her world and to a side of her that most people do not see. The two also attempt to help each other in order to improve how people view them. Unknown to them, however, people they know from school start to become curious about their strange relationship together and rumors begin to spread about them.
