After his retirement, he began college in South India. His longtime goal is to successfully carry out and finish his project, which is to create humans who can healthily live for 150 years. He decides to use Ponni as his test subject and injects the Neanderthal DNA that he has collected back in his home country into her womb. This starts having an impact on Ambuli. Wellington dopes her with strong sedatives so that she visits him often for checkups and he can carry out his tests without any problems. As she reaches her due date, she is affected too much by the sedatives and starts heading to Wellington's laboratory to get herself checked. That day turns out to be the solar eclipse, and unfortunately, she is affected by the radiation from the eclipse. This causes a big change in her womb, and thus, Ambuli is born as a beast. Seemati, who checked her pregnancy and is terrified by the looks and behavior of Ambuli, tells Ponni to kill Ambuli. But she lets Ambuli escape and commits suicide out of humiliation. Angered by this, Sengodan kills Wellington, who is the reason for all this.
