Chen Lei came out of seclusion only after he had refined this natal spiritual treasure.
After coming out of seclusion, Chen Lei also joined in the expansion of the Void City.
The expansion of the Void City and the improvement of the formation is a long and massive project that cannot be completed overnight.
While Chen Lei was helping to complete the Void City project, his attainments in formations also improved by leaps and bounds, which was a pleasant surprise.
Of course, even when he was perfecting the formation of the Void City, Chen Lei did not forget to practice, and his practice time was unshakable.
Just like that, more than five years passed in a flash.
Five years later, Chen Lei was preparing to continue to perfect the formation of the Void City, but he was stopped by a disciple and asked to go to the Demon Subduing Hall, as the deputy palace master had something to arrange.
When Chen Lei rushed to the Demon Subduing Hall, he discovered that not only him, but also some talented masters in the Yuxiao Palace had gathered in the Demon Subduing Hall.
The deputy palace master of Yuxiao Palace said after seeing everyone gathered, "I summoned you here today because I have a task to arrange. For the time being, our void crack still has five years of stability, which can be said to be a buffer period. However, the void cracks in charge of the other major sects are under tremendous pressure. We have received news that many foreign demons have come out of other void cracks and crossed the blockade of several major sects and entered the spirit world. I summoned you here today to let you return to the spirit world and clear out the foreign demons that appeared in the spirit world again, understand?"
After hearing the deputy palace master's order, the disciples of Yuxiao Palace said in unison: "Yes, sir."
The deputy palace master of Yuxiao Palace said: "Okay, then we should leave without delay. This is your mission area. After returning to the spirit world, you must rush here immediately to kill these foreign demons."
After saying that, the Palace Master of Yuxiao Palace waved his sleeves, and the jade pendants turned into streams of light and flew towards Chen Lei and others.
In the blink of an eye, these jade pendants accurately fell into the hands of Chen Lei and many other Yuxiao Palace disciples.
There was also an extra jade pendant in Chen Lei's hand. He probed his mind into the jade pendant and a specific location immediately emerged. The location marked on the jade pendant was the location of a powerful foreign demon.
However, Chen Lei's strength has been verified, and these foreign demons should not cause any trouble to Chen Lei.
Chen Lei put away the jade pendant, and then he and other disciples of Yuxiao Palace boarded a flying boat and returned to the spiritual world.
After stepping onto the ground of the spiritual world, these disciples immediately split up and headed towards the location marked on the jade pendant to eliminate the foreign demons here.
Chen Lei also rushed towards the mission area marked on his jade pendant at a very fast speed.
The area marked on Chen Lei's jade pendant is a swamp, covering tens of thousands of miles in radius.
However, this swamp did not look like this before. Instead, it was a vibrant and spiritual continent with several powerful countries and a dense population.
Unfortunately, this continent was destroyed by foreign demons, countless countries were destroyed, and the human race was devoured.
