Chen Lei shook his head, thinking that he was thinking too simply. It was not an easy task to build a bridge between Xuanyu and Zhongyu that could be used for travel at any time. This was probably the biggest problem encountered by the great man who built the ancient road outside the domain, which was why he made such a choice.
However, they can only travel back and forth once every hundred years, which Chen Lei finds hard to accept as the intervals are too long.
He couldn't keep the ancient road outside the domain open all the time, so he would find a way to shorten the interval between opening the ancient road outside the domain. If he could open it once every fifty, thirty or even ten years, it would not be in vain.
However, even if you want to do this, it is not an easy task. The energy consumed every time you open the ancient road outside the domain is too great. If it is opened like this all year round, it won’t take long before the original power of the entire Xuan Domain will be drained. At that time, the entire Xuan Domain will be completely deserted. Chen Lei doesn’t want this to happen.
For a moment, Chen Lei didn't have a good solution and felt a little headache.
Just as Chen Lei was thinking about how to completely repair this ancient road outside the domain, something unexpected happened in the void outside the domain.
On this day, the leader of Qingyang Sect and the leader of Dark Hall, Wang Ping, came to Chen Lei together to discuss important matters.
"What? In recent times, the alien race has made unusual movements?"
Chen Lei was quite surprised after hearing the news brought by the leader of Qingyang Sect and Wang Ping.
Chen Tangxuan and Wang Ping nodded, and then Wang Ping said to Chen Lei: "Based on our observations over this period of time, there are peerless masters in the alien race who are attacking the seal you left behind, and they may break it soon."
"Really? Let's go and take a look now." After hearing Wang Ping's serious words, Chen Lei did not dare to be careless. He decided to set off immediately and rush to the void outside the domain to investigate.
Back then, when Chen Lei and the alien race were fighting outside the domain, there was a space crack that led directly from the alien domain to this void in the heart of the Xuan domain.
After killing that team of aliens, Chen Lei forcibly sealed the space crack.
Originally, the seal set up by Chen Lei was enough to seal for tens of millions of years without being damaged. But now, after only a hundred years, it could no longer hold. This was really beyond Chen Lei's expectations.
But in fact, Chen Lei's cultivation level back then was far different from what it is now. At that time, he was not even at the level of Martial King or Martial Saint, so the seal he placed was naturally aimed at that level.
Nowadays, he himself has reached the upper ninth level of the Martial Emperor realm. If the space rift connecting the two worlds is discovered and attacked by a top figure above the ninth level of the Martial Emperor in a foreign land, it will indeed be difficult to support for too long.
Soon, Chen Lei summoned many powerful men such as Xiong Da, Shi Er, Wu San, as well as Nie Qianran, Bi Manman and others, and rushed to the void outside the domain with space cracks.
Soon, Chen Lei and his team arrived outside the domain and appeared near the space crack.
After arriving near the space crack, Chen Lei saw that the armies of the seven continents had surrounded the void crack tightly and were ready for battle.
In fact, this void crack is of great importance. The eight continents of Xuanyu will take turns to send troops to guard it and closely watch every move of the space crack. However, now that the Rain Clan of Xuanyu Continent has been destroyed, there are only seven armies left to take turns to guard it.
