Douluo Continent: Crossing Over to Battle Through the Heavens, Starting with a 100,000-Year Soul Rin

Xiao Wujiu transmigrated into Doupo and became a three-star Dou Zhe at the age of fifteen. Originally one of the Xiao family's twin stars, he has now become the Xiao family's number one genius!
After witnessing the third stage of Dou Qi, he activated the Double Passage Gate. When he stepped into it fully prepared, he discovered that he was actually in Douluo Continent! And this was before Tang San even touched the immortal herbs, when he had just left for Shrek Academy?
Xiao Wujiu: "Then I'm sorry, the Ice and Fire Yin-Yang Well is mine!"
While passing through the double portal, Xiao Wujiu learned that due to the different rules of the world, one sometimes has to adapt to the rules of the different worlds.
So he discovered that a sixth-tier magic core he had accidentally obtained could actually be transformed into a 100,000-year soul ring?!
From this moment on, the person who achieved the first ring in 100,000 years of Douluo history appeared!
Xiao Wujiu: "Then what else is there to say? Any of my spirit rings that are less than 100,000 years old are not even worth my attention!"
From then on, with the support of two worlds, Xiao Wujiu continued to grow until he stood at the top of both worlds!
Xiao Wujiu: "In Douluo Continent, I am the supreme creator god; in Battle Through the Heavens, I am the number one emperor of a thousand years!"
