After Chen Lei activated the Immortal Demon Transformation Technique, wisps of pure death energy and spiritual energy flew out from these dead stones and spiritual stones, sank into Chen Lei's body, and merged into his Dantian sea.
And in Chen Lei's dantian sea, all of his cultivation at this moment turned into pure gray spiritual energy.
Before this, Chen Lei practiced the Immortal Demon Transformation Technique, and the cultivation in his body was half black and half white, clearly divided.
But after receiving the Tower of Eternal Life and the Heaven-Devouring Demon Pot, his skills were influenced by the Tower of Eternal Life and the Heaven-Devouring Demon Pot and merged together, turning into pure gray.
This gray spiritual energy is purer and more powerful. At the same time, it can change more flexibly and can be transformed into black demonic energy or white spiritual energy at will.
At this time, Chen Lei was able to absorb the dead energy and spiritual energy, integrate them, and transform them into pure gray spiritual energy to improve his cultivation.
As time passed, the spiritual energy and death energy in the piles of spirit stones and dead stones in front of Chen Lei were absorbed by Chen Lei, and these spirit stones and dead stones were all turned into powder.
After absorbing and refining the spiritual energy and death energy from these spirit stones and dead stones, Chen Lei's cultivation level increased significantly again.
In the following period of time, Chen Lei practiced here. Several months passed. On this day, after Chen Lei finished his practice, his aura was shocking. He finally broke through to the seventh level of the Dao Transformation Realm.
After breaking through to the seventh level of the Dao Transformation Realm, Chen Lei's strength was greatly improved in all aspects. Both his physical potential and the depth of his vital energy were improved several times.
But this is not what makes Chen Lei most satisfied. What makes Chen Lei most satisfied is that he has re-comprehended the two kinds of rules of heaven and earth.
These two kinds of great laws of heaven and earth are the great laws of death contained in the dead air, and the other kind of great laws of heaven and earth are the great laws of life emanating from the Tower of Longevity.
The two great rules of life and death are inherently opposite, yet they contain countless mysterious connections. After comprehending these two great rules, Chen Lei's lethality and recovery ability have reached an astonishing level.
Now, Chen Lei's attack contains the rules of the Great Dao of Death. Wherever it passes, it can destroy all life. It is truly unsolvable.
The great rules of life, whether applied to oneself or added to the elixir one is refining, all have supreme miraculous effects, and can bring the dead back to life, bring the dead back to life, and turn bones into flesh.
After mastering these two great rules, Chen Lei's survival ability was greatly improved. At the same time, after Chen Lei comprehended these two great rules of heaven and earth, he no longer needed to rely on the death energy contained in the dead stone to cultivate this pure gray spiritual energy.
In the outside world, Chen Lei absorbed and refined ordinary spiritual energy, which, after being transformed by the rules of the Avenue of Life and Death, could be transformed into the purest gray spiritual energy.
After comprehending the rules of the Great Dao of Life and Death and breaking through to the seventh level of the Dao Transformation Realm, Chen Lei decided to leave this star field and return to the Thousand Faces Demon Sect.
Now, Chen Lei's cultivation has broken through to the seventh level of the Dao Transformation Realm. He can now easily defeat or even kill an ordinary master of the first or second level of the Lesser Saint Realm.
However, it might be a bit difficult for him to face off against a master above the third level of the Lesser Saint Realm, but it is enough to protect himself.
