MTL - Longevity - Chapter 27 condition

God's Seal Cathedra Rex, Part Two!Two sons of the dragon, each different; a genius elder brother and a good-for-nothing younger brother, who despite being identical twins, are worlds apart. However, they share an identical desire for peace. On the night of their birth, the moon was high in the sky.

Reincarnated as a fox by mistake, Tang Li Xue got a system that can help her evolve and reach Deity hood as her compensation.

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.
