After Chen Lei entered the hub of the formation, he could see that it was like a deep starry sky, with huge runes like stars everywhere, slowly rotating.
These star-like runes are composed of billions of small runes. The properties of these runes are divided into two types: wind and thunder.
Among them, some runes were dim, obviously destroyed, but a large part of the runes were still shining brightly, emitting terrifying pressure, which made Chen Lei feel frightened.
The powerful person who set up this formation back then had absolutely amazing attainments. At least now, it is still difficult for Chen Lei to set up such an exquisite sect protection formation.
However, Chen Lei already knew all the control methods of this formation at this time, so he naturally understood the mystery of this formation.
Chen Lei immediately saw the problem with this formation. Several key nodes were destroyed and the rune stars had completely dimmed.
These rune stars are extremely critical. Once they are destroyed, the entire formation will not be able to function and will lose its defensive and enemy-killing effects.
Obviously, Lei Yunshan also had a thorough understanding of this formation. Otherwise, it would be impossible for him to act so steadily, accurately and ruthlessly, and paralyze the Fenglei Sect's protective formation in such a short time.
However, Leiyunshan obviously did not have enough time to destroy this large formation, and he only destroyed a few key runes.
If Lei Yunshan destroyed all the runes of the sect protection formation, or destroyed half of them, it would be impossible for Chen Lei to restore the entire sect protection formation, at least not within a few years.
However, Leiyun Mountain only destroyed a few runes and a few nodes. For Chen Lei, it was not a difficult task to restore the entire protective formation.
After all, Chen Lei's attainments in formations were also very amazing. Even if he didn't know the control method of this formation, it would be a very easy thing for Chen Lei to restore these destroyed runes. What's more, now he knew every detail of this formation, so restoring the destroyed runes was even a piece of cake.
Chen Lei did not waste any time and started to restore the damaged runes.
In fact, these destroyed runes were not completely damaged, but their connection with the entire formation hub was cut off.
As long as these runes are connected to the entire formation hub again, they will naturally be able to obtain enough energy from the entire formation hub and then recover completely.
Chen Lei connected these destroyed runes with the hub of the entire formation. Then, he saw countless tiny runes flowing along the rune lines into these dim runes, making them light up again.
After the energies flowed into these destroyed runes, countless tiny runes lit up layer by layer. Finally, the light became bright and turned into a huge rune star that slowly rotated.
Several other huge rune stars eventually lit up one by one, and then instantly merged with the entire hub formation. The Fenglei Sect's protective formation was activated again.
