After Fusu left, only Su Chen and Ying Zheng remained in the main hall of Zhangtai Palace.
Something called silence filled the air.
After a moment, Ying Zheng spoke first.
He looked at Su Chen. "Young Hero Su, do you truly possess a Method of Longevity?"
Su Chen smiled faintly. "If you mean truly living forever like the immortals of legend, never aging and never dying, then I would not dare make such a boast."
"However, using certain methods to help people extend lifespan is still possible."

"Whenever their lifespan nears its end, I can intervene again and renew it. By repeating this process, one can ultimately achieve longevity for tens of thousands of years."
Seeing how convincing Su Chen sounded, Ying Zheng's heart stirred, and he began to feel anticipation.
He did not ask Su Chen to truly extend his life by tens of thousands of years.
