'Lust system': Rise of the Harem lord - Chapter 3: Lust magic Unleashed

The dawn era after the end of the half century has gradually rebuilt the order, abandoned civilization, and is full of undivided violence and desire.
The noble and powerful pioneers are in charge of the city, and the evil and mad plagues are in the wilderness.
Pure human beings who cannot mutate are the weakest, dominated by the rulers of the pioneers, and are not as good as animals in the wilderness.
A purely humanized young man with a worldly experience has quietly entered the WTO, holding a three-foot long knife and a long-distance desire to boil in the world of purgatory. From the nameless name to the sorrow of the Supreme Court, the name of the black ride is resounding!

Suddenly, a huge earthquake occurred all around the globe, throwing everyone into a desolate world.

The humans of the new world were primitive. They lived their lives facing all sorts of dangers every day, from hurricanes to attacks from huge beasts.

The humans that were brought to this world all received a totem and an egg.

Placing the totem on a certain land would turn the place into the person’s new tribe. Everyone could expand their tribes according to their strengths.

The eggs contained various beasts that would grow into humans’ most loyal companions. Humans would have to struggle to live in the desolate world with their companions and protect their own lands.

Just as Ye Chen was about to hatch his egg, he noticed he could read hidden hints.

[Monster Egg: Place a drop of blood to hatch.]

[Hidden Hint: Hatching the egg now will reward you with a Rank E Mutated Beast, Spiny Turtle.]

[Hidden Hint: Hatching the egg in 1 minute will reward you with a Rank D Mutated Beast, Dangkang.]

…

[Monster Egg: Place a drop of blood to hatch.]

[Hidden Hint: Hatching the egg now will reward you with a Rank E Mutated Beast, Yellow Horse.]

[Hidden Hint: Hatching the egg in 30 seconds will reward you with a Rank C Mutated Beast, Tiger Fish.]

[Hidden Hint: Hatching the egg in 60 seconds will reward you with a Rank SSSSS Mutated Beast, Immortal Phoenix.]

…

A few years had passed since then. Ye Chen led a group of Rank SSSSS Mutated Beasts and said confidently, “My success is the result of my hard work!”

Zhangsun Zijun and Yi Xichen are the protagonists of the novel “Record of Nine Thousand Vicissitudes.” One is solid and reserved; the other is free-spirited and uninhibited. As fellow disciples under the same master who grew up together, the two have a deep friendship that was strengthened by their numerous life and death adventures together.

However, in a popular yaoi fanfiction, the personalities of these two characters is completely OOC. Zhangsun Zijun turned into an insanely jealous, insatiable s*x addict madly in love with his wife Yi Xichen. Yi Xichen turned into a sweet, delicate little angel. Their daily life was full of kinky bedroom activities…

Suddenly, the Zhangsun Zijun character from the fanfiction was transported into the world of the original novel.
