At this time, Chen Lei focused all his attention on finding the central control hub of Qingyang Palace.
Once he has control over the entire Qingyang Palace's control hub, then all other people in Qingyang Palace will be completely under Chen Lei's control, and he can control them however he wants.
Chen Lei displayed his skills and flew quickly to the depths of Qingyang Palace. He did not bother to take any of the treasures he encountered along the way.
There is no point in collecting these treasures now. After finding the hub of the entire Qingyang Palace, all the treasures will belong to him.
Chen Lei flew as fast as lightning towards the deepest part of Qingyang Palace.
There is a huge space formation arranged here, and the internal space is so large that it is almost boundless.
Chen Lei directly used the Lightning Void Step, but even so, it took him dozens of days to reach the deepest part of Qingyang Palace.
At this time, Chen Lei stopped at the top of a lapis lazuli mountain, looking at a huge thunder pool on the top of the mountain with huge thunder waves, and couldn't help being moved.
This huge thunder pool is obviously the central hub of Qingyang Palace.
Chen Lei had not expected that the ancient Qingyang Palace would be so generous as to build a thunder pool as a hub.
This thunder pool is not the artificially imitated thunder pool in the Thunder Emperor Palace, but a real naturally formed thunder pool.
Chen Lei once obtained a natural thunder pool, which was found at Xuan Lei Peak of Xuantian Sect.
However, the gap between that thunder pool and the one in front of him was too huge. It could be said that the thunder pool in Qingyang Palace was completely at the grandfather level, while the thunder pool in Xuanlei Peak was not even at the grandson level.
Chen Lei was looking at the thunder pool at this moment, knowing that a great opportunity was right before his eyes.
If he could refine this thunder pool as well, then it wouldn't matter at all even if he couldn't get the Qingyang Palace.
Chen Lei collected his thoughts, sat cross-legged on the top of the mountain, emitting his spiritual sense, and began to refine this thunder pool directly.
If it were an ordinary person, as soon as his consciousness left the body, it would be wiped out by the enormous power of the thunder pool.
But Chen Lei is different, because he has a real thunder pool in his body, and his spiritual consciousness has been refined by the thunder pool countless times, and is extremely pure and solid. Therefore, although this thunder pool is huge and powerful, it cannot erase his spiritual consciousness at all.
As Chen Lei's spiritual consciousness was refined, this thunder pool gradually began to bear Chen Lei's mark.
Although this thunder pool is powerful, it has existed for countless billions of years and has long become ownerless.
Such an ownerless object had been refined by someone before, so it was not a difficult task for Chen Lei to refine it now.
At the same time, Chen Lei also has unparalleled experience in refining the thunder pool. Therefore, Chen Lei's refining of this thunder pool was very smooth.
A month had passed since Chen Lei finished refining the thunder pool. He had already mastered nearly 90% of it.
In the past month, the entire Qingyang Palace and every hall have been turned upside down by many powerful people from the Qiankun Holy Land, Lingxu Holy Land, Juntian Holy Land and other places, and the harvest is huge.
