The strong man of the sea clan with a crocodile head and a human body had a red face, veins bulging on his forehead, and a large amount of true energy light rising from his body. He even used all the true energy in his body, but still could not do anything to the tripod.
At this time, the hall was empty, and the other several strong men all rushed into the depths of the hall.
The powerful sea creature with a crocodile head and a human body suddenly slapped his head and said to himself: "I am so stupid. Why don't I collect the treasures that can be obtained, but instead compete with this treasure tripod."
Only now did the powerful sea creature with a crocodile head and a human body come to his senses. He gave up the tripod and flew towards the depths of the hall.
At this time, Chen Lei had already looted all the skills in the scripture libraries along the way.
As soon as Chen Lei entered the hall, he saw several supreme treasures including the precious tripod, the divine furnace, and the holy map.
However, Chen Lei knew that with his current strength, there was no way he could subdue these treasures.
The restrictions on those treasures were simply beyond their current capabilities to break.
Therefore, if you spend all your energy on those treasures, it would be a sheer waste of time.
Therefore, Chen Lei did not hesitate to abandon those treasures and instead rushed towards the depths of the hall.
Deep in the hall, there must be various martial arts classics, and this is the main purpose of Chen Lei's coming here.
And Chen Lei was indeed not wrong in his guess. In the several halls at the back, there were indeed countless books on martial arts.
However, these martial arts manuals do not have any restrictions at all and can be collected at will.
Chen Lei was like a swarm of locusts, sweeping away all the martial arts books and manuals he saw.
Since these martial arts manuals can be placed in the main hall of the Xuanwu Cave Mansion, they are naturally extraordinary items.
In fact, Chen Lei had taken a rough look at some of them and knew that these martial arts books were indeed rare masterpieces.
These books on martial arts are all-encompassing, not only containing the martial arts practiced by the human race, but also the martial arts of various races such as the demon race, the sea race, the war race, the wild race, the barbarian race and even the alien race, and all of them are top-notch martial arts.
Chen Lei just happened to lack these top-level skills. Although he could not practice the skills of other races, it would be beneficial for him to understand some of them.
Finally, Chen Lei walked to the deepest part of the hall and saw an altar.
This altar is as tall as a mountain, covered with huge and mysterious runes, and filled with the energy of the Great Dao.
Above the altar, there was a ball of light with a radius of more than ten feet suspended. Inside the ball of light was a tortoise shell that was about several feet in size.
It is not entirely appropriate to call it a tortoise shell. It should be the shell left by the mythical beast Xuanwu.
This shell exudes a bright and precious light. Around it, the void keeps collapsing and disappearing. Rays of star power keep descending from the void and merging into the shell. One can even see fragments of time surrounding it. It is an astonishing sight.
With Chen Lei's eyesight, he could also see that there were words engraved on this shell.
These words describe the inherited skills left by the mythical beast Xuanwu.
The Xuanwu mythical beast has long transcended the category of race. The skills and great principles it left behind can be practiced and learned by any race, and they can reap huge rewards.
