Chapter 130: Chapter 122: Strengthening the Lungs._2

This kind of enhancement made Su Lin feel very satisfied.

He looked at the remaining vial of Strengthening Serum and took it out again!

Su Lin's tolerance for pain had become very strong,

which led him to decide to bite the bullet and use the second vial of Strengthening Serum as well.

"Ding! Do you want to use the Strengthening Serum?"

"Use."

As the scalding energy from the serum emerged once more, Su Lin felt that the pain was much more intense than the first time.

But it was still within his tolerance.

Clenching his teeth tightly, he endured it.

This time, the scalding energy moved quickly, not as slow as when it fortified his meridians.

In no time at all, it surged towards Su Lin's lungs.

An extreme pain erupted from his lungs suddenly, making it somewhat difficult for Su Lin to breathe.

The feeling of suffocation made his vision darken.
