Chapter 4275 Underwater World

Only at that moment did the underwater world fully reveal itself before the two of them.

What filled their sight was a house shaped like a shell. The house was not big, but it could accommodate several adults. On the ground surrounding the house, there were countless seaweeds resembling terrestrial plants, giving an impression of a farmland.

Jacob glanced at the plants, taken aback. "Sea Spirulina?"

"Master, what is this?" Gunner asked.

"This is a very precious treasure of nature, belonging to the class of spiritual drugs," Jacob explained. "It is incredibly hard to find, and I always thought it had disappeared from this world. But unexpectedly, we have found it here, growing in the underwater world."

"Master, what's its use?" Gunner asked.
