The level of the martial artist is from the first layer to the ninth layer of internal strength, corresponding to the first to ninth level of the fusion degree of the genetic person, and corresponding to the first to ninth layers of the qi refining period.

The level of cultivation is divided into: Qi refining, foundation building, knotting, Yuanying, transforming gods, refining void, merging, Mahayana, and true immortals

The protagonist Li Ruofan is an ignorant cultivator with chaotic qi in his body, the last cultivator on earth.

Li Ruofan's parents entered the ranks of cultivators after eating the Qi Refining Pill.

The probability of success of genetic injection is extremely low, and even if it is successful, there will be two major risks: the danger of explosion or the continuous reduction of fusion. Human genes are naturally protected and rejected by foreign genes.

Martial artists cultivating muscles, bones, and skins will have hidden diseases and dark wounds.

Even for cultivators, the direction of the main attack is different. For example, the nine-tailed fox in the demon clan cultivates not strength, but the charm of the direction of spiritual power. Like Bai Suzhen, who cultivates in the direction of spells, naturally there are also those who major in the direction of power.

Many Dan masters or rune masters in the cultivation realm have very low force value, and their means of life preservation and attack all rely on poison pills, cartilage pills, rune paper, and rune arrays.

Of course, the novel is mainly written about the story of the mortal earth. The plot and characters are completely fictional, although there are depictions of officialdom officials, none of which have anything to do with reality.
