A continuation from where High School DxD Volume 25 left off.

Meng Qianqian, at the age of 15, married into the Lu Family to bring joy to the elderly matriarch.On the wedding night, urgent news arrived from the border that her husband had been commanded to go to war. Six months later, he tragically died at the hands of Beiliang soldiers.Five years later, the husband who had been presumed dead returned, and by his side was an ethereal mute woman named Wan'er.Lu Lingxiao said that Wan'er was the descendant of a loyal and righteous family, entirely different from her—a merchant girl reeking of copper coins. He claimed Wan'er was a true paragon of noble character.Lu Lingxiao also said that Wan'er was an eagle soaring in the heavens, while someone like her was nothing more than a fragile flower, unworthy of comparison.It was not until the land was broken, the city walls fell, and she wielded a Red Tassel Spear to crush countless soldiers that Lu Lingxiao realized he had misjudged her.She was not a delicate flower confined within the depths of the mansion; she was the fiercest west wind of Yumen Pass.

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.

[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.]

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!”
