After Chen Lei stopped the silver-haired rat demon ancestor, the lightning in his hand condensed into a thunder sword again. With faint lightning light, he chopped down the silver-haired rat demon ancestor fiercely.
The sword light slashed down and hit the silver-haired rat demon in an instant.
Chen Lei's sword light was so fast that the Silver-haired Rat Demon Ancestor could not dodge it.
“Swish!”
The lightning sword broke through the layer of silver light outside the body of the Silver-haired Rat Demon Ancestor and slashed at the body of the Silver-haired Rat Demon Ancestor, leaving a deep sword mark on the skin of the Silver-haired Rat Demon Ancestor, and drops of silver blood rain fell down.
Chen Lei's sword almost cut the silver-haired rat demon ancestor into pieces.
The silver-haired rat demon opened his mouth and spit out twelve silver cold lights, which instantly broke through the void and attacked Chen Lei.
These twelve silver cold lights were extremely fast, restrained in their brightness, and contained endless power. In the blink of an eye they were close to Chen Lei.
Chen Lei swung the thunder sword in his hand continuously, and in a flash, he cut through the twelve cold lights, splitting the twelve cold lights instantly into the void.
“Boom boom boom…”
Rays of cold light exploded one after another, and the power fluctuations emitted directly destroyed dozens or hundreds of stars.
Amid the light of the explosion, the silver-haired rat demon fled again, trying to take this opportunity to escape Chen Lei's sight and escape Chen Lei's pursuit.
However, Chen Lei’s divine consciousness enveloped the sky, making it impossible for the Silver-haired Rat Demon Ancestor to escape.
In the blink of an eye, Chen Lei's figure turned into lightning and chased after him again.
The silver-haired rat demon was quite powerful, but under Chen Lei's full pursuit, he still could not escape Chen Lei's pursuit. After hundreds of moves, he was blasted to death by Chen Lei in the void.
Chen Lei then extracted the rules of heaven and earth mastered by the Silver-haired Rat Demon Ancestor and refined them into the Thunder Realm.
After Chen Lei killed the silver-haired rat demon, countless demons from outside the domain were completely speechless and could not believe this scene.
The ancestor of the silver-haired rat demon has a very high status and prestige among the demons from outside the domain. Although he is not the number one demon among the demons from outside the domain, he can definitely be ranked among the top five.
However, even such a powerful demon ancestor is no match for Chen Lei. No matter how stupid the other foreign demons are, they know that they are no match for Chen Lei.
Therefore, the remaining demons from outside the domain no longer dared to surround and kill Chen Lei and die in vain.
After Chen Lei killed the Silver-haired Rat Demon Ancestor, while extracting the rules of heaven and earth from the Silver-haired Rat Demon Ancestor's body, he also read the Silver-haired Rat Demon Ancestor's memory.
Through the memory of the Silver-haired Rat Demon Ancestor, Chen Lei learned that the entire outer space was actually controlled by the five great demon ancestors, or in other words, these five demon ancestors were the most respected.
As long as these five demon ancestors are destroyed, the demons outside the domain will be reduced to loose sand and will never threaten the spiritual world again.
Chen Lei knew from the memory of the Silver-haired Rat Demon Ancestor that the five great demon ancestors were three demons and two monsters.
The three demons are the Blood Demon, the Bone Demon and the Sky Demon.
The two monsters are the Pig Monster and the Ox Monster.
Each of the five demon ancestors, including the three devils and two monsters, possesses unfathomable and terrifying strength, which is several times stronger than the silver-haired rat demon ancestor.
After Chen Lei understood the strength of the three demons and two monsters, he decided to kill them all. With his current strength, killing the three demons and two monsters should not be a problem.
