In fact, even the eighth-level formation disk provided by Chen Lei cannot be opened for a long time. It can only be opened in the most dangerous time.
You know, the activation of this formation requires a large amount of heaven and earth energy, or spiritual energy. However, in this sky battlefield, the heaven and earth energy and spiritual energy are extremely scarce. Even if everyone has a large number of Yuan Crystal Stones in their hands, it is impossible to supply the formation for a long time.
On the contrary, it was the formation of the Hundred Races Alliance that consumed the bloody evil energy that was omnipresent in the sky battlefield and could be activated at any time.
However, the formation model that consumes blood evil energy to provide defense is too mysterious. Although Chen Lei has deduced such a formation model, there is still a long way to go before it can be applied in practice. For the time being, he can only rely on the eighth-level formation plate provided by Chen Lei to establish a position to block the enemy, and then rearrange it after conquering the formation powered by blood evil energy in the future.
At this time, Emperor Bone Ridge was the first line of defense established by the Hundred Races Alliance.
The situation in the Meteorite Sea has begun to become unfavorable to the races of the Eight Clans of the Xuanyu Continent, but they cannot give up easily.
You know, the Meteorite Sea is a rare treasure land in the sky battlefield. If it is given to alien races, it will definitely be a huge loss for the eight continents of Xuanyu.
Therefore, Chen Lei asked these frightened warriors to leave first, and he went with Nie Qianran and others to see how much of the Meteorite Sea had fallen into the hands of aliens.
Chen Lei and others moved towards the Meteorite Sea and found that the situation was indeed not optimistic, because in most areas, there were alien figures appearing in groups and in organized organizations, and they had completely controlled most areas of the Meteorite Sea.
Chen Lei and others also encountered several groups of besieged humans. They actively helped and rescued the trapped humans, and even rescued several groups of powerful monsters from the demon tribe, sea tribe and barbarian tribe.
After Chen Lei rescued these powerful men from various tribes, he asked them to rush to the Emperor Bone Ridge to reunite, while he continued to explore the depths of the Meteorite Sea.
With Chen Lei's current capabilities, as long as he was determined to hide, it would be impossible for ordinary aliens to discover his whereabouts.
As for Nie Qianran and others, since this matter was too dangerous, Chen Lei had asked them to return first and wait for him at Di Gu Ridge.
Chen Lei sneaked all the way, trying to find out how much of the Meteorite Sea was occupied by alien races.
The deeper he went, the more shocked Chen Lei became. In just a few days, the aliens had occupied as much as 70% to 80% of the Meteorite Sea. Moreover, wherever Chen Lei passed, he could see countless powerful aliens, each of them exuding an extremely powerful aura.
At the same time, Chen Lei also saw countless tragic scenes. The number of humans killed by alien races was countless, as many as hundreds of thousands. Of course, in addition to humans, there were also monsters, sea creatures, barbarians and other races. All of those who were killed were eaten by alien races, leaving only bones all over the ground.
No matter whether it is human, demon, barbarian or sea race, as long as it is a race that cultivates vital energy, it is the best food in the eyes of alien races and has a fatal attraction to them.
Devouring flesh and blood that carries vital energy can make the alien race quickly become strong.
