And this Six Deadly Demons once left behind a set of martial arts skills, which was obtained by someone and once appeared in the black market.
The two powerful werewolf warriors had seen this technique before, but they were not interested in it, so they did not buy it.
However, after Chen Lei searched out this information from the Nascent Souls of two powerful werewolf warriors, he took it to heart.
After all, the situation of these six heavenly demons is not much different from his.
The Six Absolute Heavenly Demons cultivated six Nascent Souls. Although the number was three less than Chen Lei's, Chen Lei knew that it would definitely not be easy for the Six Absolute Heavenly Demons to break through to the Nascent Soul Realm.
And since this Six Absolute Heavenly Demons has broken through to the Yuanhun Realm, he must have some unique method.
If Chen Lei could obtain the martial arts that Liu Jue Tian Mo had practiced, he might be able to find out the secret of Liu Jue Tian Mo's breakthrough to the Yuanhun realm.
Therefore, this is Chen Lei’s main purpose for coming to this black market.
Chen Lei stopped in front of a rather old stall.
The owner of this stall is an old man, whose cultivation level is around the third level of Yuanhun Realm.
On the old man's stall, there were a few worn-out secret books and a few black stones, none of which looked very impressive.
Chen Lei came to the stall and looked at the several worn-out secret books on the stall.
"Um?"
When Chen Lei's gaze fell on a few worn-out secret books, his eyes were stern. These worn-out secret books were actually all high-level Qi-refining techniques, which were priceless in the outside world.
However, here, these worn-out secret manuals were sold for only 100 magic crystals each. This was simply too cheap.
"Brother, are these secret manuals really sold for only one hundred magic crystals?" Chen Lei still couldn't believe it and asked the old man.
"Yes, if you want, I can give you a 10% discount."
The old man said that when he saw the business coming, a gleam of light flashed in his dim old eyes.
Chen Lei looked at these secret books and found that the martial arts technique left by the Six Absolute Heavenly Demon was also among them.
Chen Lei got the information by searching the souls of two werewolf Yuanyings, so he was able to find the old man directly.
What he was most worried about was whether the skills left by the Six Absolutes Demon would be bought by someone during this period of time. But now it seems that his luck is not bad, and no one has bought the skills of the Six Absolutes Demon.
After all, there are very few strong people who can cultivate multiple Nascent Souls. The Six Absolute Heavenly Demons is already an extreme exception. It is useless for others to obtain the Six Absolute Heavenly Demons' skills.
Therefore, this old man's Six Absolutes of the Heavenly Demon technique has never been sold.
In fact, in the entire Purgatory battlefield, the least valuable things are these skills.
This was because all these techniques needed to absorb the spiritual energy of heaven and earth in order to be practiced, but this battlefield of purgatory was filled with demonic energy and no spiritual energy at all, so no one was interested in these techniques.
This old man had been injured outside recently and has not fully recovered yet. He dares not leave the black market at all.
Once he steps out of the black market and encounters monsters, he will surely die.
Staying in the black market to recuperate is also a huge expense for this old man. Every day, he has to pay a certain amount of magic crystals to the black market in order to stay in the black market.
