Global Awakening: Only I Can Respawn - Chapter 94: Final Trial? (2)

Tang Long was brought to the Immortal Cultivation World by an immortal who noticed his affinity to wood and cultivation.
Relying on his amazing talent, became one of the five emperors of that world.
He failed his Heavenly Tribulation and had his soul scattered into pieces but one part found its way to Qin Haodong on Earth.
With his excellent medical skills, he became a divine doctor of traditional Chinese medicine and encountered the baby girl he made before going into the Cultivation World, whose mother was as pretty as a fairy. The little girl even asked him to find more lovers. What a cute girl…

At level 2, most people unlocked their first talent; those who didn’t were considered fortunate, as they had the potential to unlock rarer talents requiring higher levels. The world’s most rare and powerful talents were revealed at level 5. But what if someone didn’t obtain a talent? Luck quickly turned to misfortune as they were labeled talentless, with no hope of gaining a talent. Sol was one such person who was unable to unlock his talent, but he refused to give up. He persistently fought and trained every day, slowly increasing his level despite the disadvantage in skills. He held onto the hope that, one day, he would be bestowed with a talent like everyone else. As years passed, his determination began to wane until one fateful day. You have leveled up! +5 Free stats. Talent Unlocked - [Siphoner]! This event marked the beginning of his story.
