At this time, Chen Lei, Jingjing and Li Hanxing had already left this troubled place far away and found a secluded place to stop.
Afterwards, Chen Lei raised his hand and set up a hidden formation here to hide them. The main purpose of doing this was to reduce some trouble, because Chen Lei had to refine this Thunder Gourd within this period of time.
With the protection of the formation and the guards of Jingjing and Li Hanxing, Chen Lei felt very relieved and began to refine the Thunder Gourd he had obtained.
Chen Lei sat cross-legged on a piece of bluestone, took out the Thunder Gourd, and then began to refine it by activating the skills in the Thunder Emperor Sutra.
A trace of pure lightning energy overflowed from the Thunder Gourd and merged into Chen Lei's body, constantly strengthening his physical body, as well as his true power and spiritual power.
These lightning energies did not have the slightest destructive aura, but were full of vitality. Their effects were comparable to those of the Thunder God's Liquid, greatly improving Chen Lei's cultivation.
As he refined the lightning energy in the Thunder Gourd, Chen Lei's cultivation level increased rapidly. He broke through one small realm after another, and finally, he reached the peak of the ninth level of the Martial Ancestor Realm. His soul cultivation level also increased hundreds of times. Although Chen Lei's soul cultivation level is still at the Martial Ancestor Realm, it can be compared with the strong men at the second and third levels of the Martial Emperor Realm. As for his physical body, it has reached an extremely abnormal level.
In the end, Chen Lei completely refined the Thunder Gourd. Under normal circumstances, Chen Lei would naturally choose to transform the Thunder Gourd into a martial soul. However, the Thunder God Lotus martial soul in his body was much more powerful than this Thunder Gourd. Therefore, Chen Lei only refined the Thunder Gourd a little bit and turned it into a powerful treasure.
This powerful gourd treasure can emit endless lightning, has the power to destroy the world, and its lethality is terrifying.
At this point, Chen Lei had another big trump card in his hand, and his strength increased several times again.
After refining the Thunder Gourd, Chen Lei stood up and asked Li Hanxing and the others how many days had passed.
While Chen Lei was refining the Thunder Gourd, Li Hanxing and the others had been calculating the time and told Chen Lei that three months had passed.
Chen Lei calculated carefully and found that they had entered this secret realm on the sea for five months. In less than a month, this secret realm on the sea would be closed.
There is only one way to get out of this secret realm on the sea, and that is to go out through the entrance. This entrance will only be opened at a specific time and will only last for one hour.
If you miss the entry and exit time of the secret realm on the sea, then the secret realm on the sea will be closed, and the people trapped inside will be swallowed by the secret realm on the sea and turned into nutrients for the secret realm on the sea.
Therefore, what they have to do now is to rush to the entrance of the secret realm on the sea in advance and make preparations before leaving. As for searching for other opportunities, it is no longer the top priority for Chen Lei and his friends.
The three of them all gained something in this secret realm on the sea. The richness of the harvest has far exceeded their previous expectations. They are no longer dissatisfied. Now they just need to wait quietly for the entrance to the secret realm on the sea to open.
