At this moment, Qin Yuan couldn't help but feel happy in his heart. This dolphin is indeed a master of curing diseases and saving lives. These three options seem to be very useful!

Qin Yuan looked at these three choices and directly chose the second item. After all, Qin Yuan knew that the dolphin's sonar detection ability was very strong, and even the sonar in the submarine was created by imitating the dolphin!

Qin Yuan also lacks some ability to explore the seabed, so he naturally needs to get this ability first!

"System, I'll choose the second option!"

"Dingdong, congratulations to the host for obtaining world-class sonar exploration ability, which can help the host explore all creatures and obstacles within a radius of one thousand meters in the ocean!"

"Oh, it was 1 kilometer from the beginning?"

Qin Yuan couldn't stop being surprised. He thought that his sonar exploration ability was similar to night vision ability, and he had reached the top level, about five thousand meters, but now it was 1 thousand meters, so Qin Yuan couldn't help but get it.

Not surprised!

Moreover, because of the obstacles of water flow, no matter what kind of creature it is, its speed in the sea water is not very fast. With Qin Yuan's current swimming speed in the water, no matter what happens, it is enough to react to Qin Yuan.

Opportunity.

Qin Yuan looked at the active dolphins around him, and immediately smiled and rushed over, receiving all the dolphins into the grid. Then he made a series of choices to directly upgrade the sonar exploration ability to the universe

class.
Chapter completed!
