The effect this time was astonishing, and nearly a hundred masters outside the Sin Domain were killed. After this incident, there are probably not many masters outside the Sin Domain left, and they cannot cause any trouble.
The reason why Chen Lei was able to kill so many masters outside the Sin Domain this time was that he self-destructed the Soul Refining Tower.
Inside Chen Lei's soul refining tower, there are also the souls of nearly a hundred masters from outside the domain, constantly undergoing the torture of refining.
This time, facing the crisis, Chen Lei directly detonated the Soul Refining Tower. The power of the explosion of the souls of nearly a hundred powerful outsiders was earth-shattering, and it exerted a destructive power.
It was also because of this that he was able to wipe out the more than one hundred foreign masters who attacked him.
After defeating these masters from outside the domain, Chen Lei raised his hand, collected the storage rings one by one, and then turned and left.
And this time, no one dared to chase Chen Lei.
Even though they knew Chen Lei was seriously injured, no one dared to attack him.
After Chen Lei left this time, he found a place to heal his wounds. After a few days, his injuries were completely healed.
After Chen Lei recovered from his injuries this time, he did not go out again, but found a place and began to practice in seclusion.
He has now reached the Spiritual Soul Realm, and it is somewhat difficult for him to break through to the Spiritual Sea Realm. However, there is no bottleneck in cultivating to the Great Perfection of the Spiritual Soul Realm. He only needs to use various spirit stones and elixirs.
He now has treasures left by nearly two hundred masters from outside the domain, and he has no shortage of various resources for cultivation.
Therefore, he can now retreat for a period of time and improve his cultivation to the ninth level of the Spiritual Soul Realm.
After spending several years, Chen Lei's cultivation finally broke through to the ninth level of the Spiritual Soul Realm.
After breaking through to the ninth level of the Spirit Soul Realm, Chen Lei's combat power naturally became much stronger.
In the past few years, the sects outside the domain have stopped sending disciples to the Sin Domain.
More than 200 elite disciples from various sects outside the domain all died in the sin domain. This was hard to imagine in the past.
These sects knew that an unrivaled strong man had appeared in the Sin Domain, and that sending more masters to the Sin Domain would be useless, as they would just be sending their heads to the Sin Domain. Therefore, each sect would no longer do such a stupid thing.
Even the Silver Holy Sect, after losing an innate spiritual object, did not think of recovering it, because even if they sent out more disciples, they would not be stronger than Xu Zhilong.
In this way, the Sin Realm finally calmed down.
Moreover, after several years, some surviving disciples outside the Sin Domain had reached the end of their training period and were no longer allowed to stay in the Sin Domain, but had to return to their respective sects.
There are also requirements for the time when these disciples return to their respective sects. After these masters from outside the domain return, the various sects responsible for guarding the Sin Domain will completely close the passage between the Sin Domain and the outside world.
Once the passage between the Sin Domain and the outside world is closed, the Sin Domain will become a dead place, unable to connect with the outside world.
Chen Lei naturally knew this, so he ended his retreat at this time.
Chen Lei, who had just finished his retreat, wanted to leave the Sin Domain and head to a wider world through the channels connecting these sects and the Sin Domain.
