Hunt the Ghost Hair Jellyfish

The hole in the reef had already been opened up by the electric eel to 20 meters in diameter and 100 meters in depth. If all the seawater here had been emptied, the experts would definitely think that it was another big hole created by an aerolite. 

After days of putting in effort, the electric eel could already dive to 2,000 meters deep, but it still needed a few more days of training to be able to move around freely for a long period under that pressure range. Otherwise, it wouldn't be able to do anything when it reached Tonga Trench.

Reaching Shimen Trench again, Chen Fan decided that he would only go back after the electric eel was able to not feel any pressure at more than 2,000 meters deep. After that, he would prepare to go straight to Tonga Trench to catch the ghost hair jellyfish.

Arriving under the cliff where it previously found the treasure box, Chen Fan turned the output power of the eel's discharge to the maximum to test the terrain below.
