However, the grade of this divine furnace is too high and Chen Lei is not able to refine it now.
As soon as Chen Lei sat cross-legged in front of the divine furnace, he felt a huge pressure coming. The divine furnace was spiritual, and if one wanted to refine the divine furnace, he would have to get the recognition of the divine furnace.
At this time, Chen Lei was sitting cross-legged in front of the divine furnace. He was not thinking about refining the divine furnace. Instead, he started to practice Qi refining techniques.
Previously, Chen Lei's cultivation level was at the seventh level of Lingyuan Realm, and no matter what, it was difficult for him to break through to the eighth level of Lingyuan Realm.
The reason for this is that, firstly, he encountered a bottleneck, and secondly, the spiritual energy outside Ziyun Mountain was too thin to support Chen Lei's breakthrough.
The spiritual energy in Tianjun's villa is extremely rich, probably even richer than the deepest part of Ziyun Mountain.
Moreover, the spiritual energy here is extremely pure and does not require excessive refining before it can be used for one's own benefit.
Chen Lei started to practice Qi Refining Technique at this moment. All of a sudden, countless spiritual energy rushed into Chen Lei's body, flowing continuously. Even the sound of roaring waves was heard in the void.
At this time, Chen Lei's body turned into a bottomless pit, madly devouring the spiritual energy.
When Qin Yaoer saw this scene, she was stunned.
Because the speed at which Chen Lei absorbed spiritual energy at this time was really too astonishing.
Even though Qin Yaoer had seen many amazing geniuses, she couldn't believe that there was someone who could devour spiritual energy at such a terrifying speed.
Now, Chen Lei can no longer be described as refining, it is completely devouring.
Almost all the spiritual energy in the entire Tianjun Villa was attracted by Chen Lei and gathered towards this area.
In the end, these rich spiritual energies turned into spiritual liquid, which continuously poured into Chen Lei's body.
An ordinary genius, if trained with such a brutal and violent method, would probably have been blown up in the first place.
However, Chen Lei is different. His physique is extremely strong and abnormal. All the meridians in his body are open. After being tempered by the heavenly tribulation, he is extremely tough. Even such a huge amount of spiritual energy does not put any pressure on Chen Lei's body.
With such rapid training, Chen Lei's realm began to break through.
Soon, Chen Lei broke through to the eighth level of Lingyuan Realm, and then continued to advance rapidly, suddenly reaching the ninth level.
As Chen Lei broke through to the ninth level of the Lingyuan Realm, countless spiritual energy turned into a huge vortex in Chen Lei's dantian, slowly rotating.
Gradually, within the vortex, the extremely pure spiritual energy began to crystallize and turned into transparent spiritual crystal particles the size of rice grains.
These spirit crystal particles are mixed in the liquefied spirit energy, like a huge star field, beautiful yet full of dangerous aura.
These crystal particles eventually became more and more numerous, and finally merged together to form a transparent and crystal clear Yuandan.
At this time, Chen Lei actually broke through to the Yuandan realm.
At the moment when Chen Lei's Yuandan condensed into shape, within Chen Lei's sea of soul, when he was undergoing the tribulation, the spirit bead transformed from Chen Lei's martial soul, the Tribulation Thunder Lotus, quickly sank and appeared in Chen Lei's Dantian sea. This spirit bead directly merged into one with the Yuandan that had just condensed into shape.
