Sure enough, Wang Yan had indeed come with a certain matter this time.
"Elder Brother Yunmu, we were doing a mission last month when we discovered a secret cave…"
Wang Yan recounted the crucial events of their previous mission, until the existence of a secret underground cave came to the surface.
Only, did they really find this secret underground cave because of something unexpected while doing a mission? Li Yunmu naturally didn't believe her words. In his opinion, this was definitely one of the secrets for which the descenders had come to join Blue Moon Sect.
They were just like him who had been told by Battle Sage Vega to come to this place and find a secret location. Li Yunmu just prayed that the secret region she had asked him to find wasn't the same one which Wang Yan was talking about.
Otherwise, this would make it extremely difficult for Li Yunmu to infiltrate the upper echelons of Blue Moon Sect and may even expose his identity.
"This is…"
After Wang Yan was done recounting the details of the mission and mentioned the matter of the secret underground cave, she took out an intact manuscript.
"This is a training method to improve a body's defences to a formidable level. Brother Zheng Quan said that as long as Brother Yunmu helps us with our task, this will be your reward," Wang Yan said while looking at Li Yunmu with longing.
"Cross Cover Armor!"
At the first glance, Li Yunmu's mind was jolted slightly.
This was indeed an extremely formidable limit breaking method which allowed someone with a tyrannical physical body to display their defense to the extreme.
Earlier, when Suo Lei used this skill, the flesh under his precise control had divided into several square-shaped pieces and formed an armor. From the outside, it looked as if he was wearing an armor of hardened flesh.
If Li Yunmu cultivated this skill to a minor threshold, he could fight against blades and knives with his bare hands, while if he cultivated this skill to a major threshold, he could resist natural calamities with his body alone.
From the skill choice, it became even more clear that Azure Dragon Island's hall mater Bu Jie had been assassinated by these people. They seemed to have gained a great harvest from him.
At the moment, Li Yunmu was certain that this Cross Cover Armor copy was part of Bu Jie's inheritance. Otherwise, they would have to have the original manuscript of this limit breaking method.
Li Yunmu thought about it, then agreed bluntly. "Alright, I agree, so when you are all prepared to go out, contact me."
"Then I will give this manuscript to you first. It would be best if you used the time until the expedition to cultivate it."
Wang Yan suddenly delivered the manuscript to Li Yunmu.
"Huh? If you do this and Zheng Quan discovers, won't it be embarrassing for you."
Li Yunmu hesitated slightly, not accepting the manuscript right away.
Wang Yan's actions caused him to hesitate. It wasn't that he didn't want this, but he had never anticipated that she would just quietly deliver this manuscript to him.
He was certain that a leader like Zheng Quan would never act in such a relaxed manner. Then this woman in front of him, could she have decided on this on her own?
"As long as Elder Brother Yunmu doesn't say anything, no one will know. Truth be told, that secret underground cave is extremely dangerous. Elder Brother Yunmu, take my advice and cultivate it, but unless you run into extreme danger, don't display it to others…"
Wang Yan handed over the manuscript and quickly ran away.
Once she was gone, Li Yunmu still felt a little awkward while holding the manuscript.
He hadn't expected that a woman from another plane would become so passionate about him that she would even reveal her own secret.
"System, how is this Cross Cover Armor?"
Li Yunmu shook his head, putting this matter at the back of his mind. He recorded the manuscript in the system for storage and comprehensive scanning.
In truth, Li Yunmu wasn't knowledgeable about the differences between limit breaking and body refining methods.
When he killed Devil, he had obtained various cultivation methods of the Ghost Clan. Among them was Ghost King's Body Refining Method, which was a pinnacle level cultivation method.
However, there was a stringent condition needed to be fulfilled to cultivate it. This condition was that he must possess the bloodline of the Ghost Clan.
Thus, this Cross Cover Armor that had no conditions was a perfectly suitable method for Li Yunmu to train his defense.
[This Cross Cover Armor is at least A grade. If it could be repaired, it could even approach S level. This method is extremely suitable for natives who have innately formidable bodies. It can strengthen their physical bodies to the extreme, and the more formidable is one's cultivation, the more formidable would be the effects of this cultivation method.
[It would be best for host to cultivate this cultivation method together with Great Sun Thunder Tyrant Body Muscle Marrow Secrets and Devil Dragon Bone Refining Secrets. After cultivating this method, the defensive strength of the host's physical body will be displayed to the extreme.]
As expected, the system gave a high evaluation for Cross Cover Armor.
According to Li Yunmu's thoughts, this limit breaking cultivation method had to be at least B grade. But what he hadn't expected was the system declaring that under special circumstances, it could even surpass Ghost King's Body Refining Method.
After hearing this, Li Yunmu obviously wouldn't miss the chance to train this method.
Presently, the cultivation of his Great Sun Thunder Tyrant Body Muscle Marrow Secrets had reached a bottleneck because the source energy required to cultivate this method far surpassed the level of flux energy and dark flux energy.
Even the system's ability points couldn't be used to upgrade it. So he had to wait until the system had been upgraded to the tenth level, when it could research and create an all new type of energy unit which could finally be used to upgrade the Great Sun Thunder Tyrant Body Muscle Marrow Secrets.
However, the system was only at the fifth level currently, which has opened an all new hacking feature. The shadows could now be detached from his mind and hack in the entire world.
But the system was still a long way off from being upgraded to the sixth level. To achieve it, it needed to absorb a special item.
Thus, the system's upgrade had also stagnated for the time being, because of which he couldn't advance the cultivation of Great Sun Thunder Tyrant Body Muscle Marrow Secrets. Thus, regardless of whether it was the Great Sun or Tyrant Body, the cultivation of both had been left to stay at a minor threshold.
Otherwise, if Li Yunmu could cultivate them to a higher level and accumulate more of the flame thunder energy, he wouldn't need to advance step by step by rising from flux expert to great flux expert to sage flux expert.
Therefore, Cross Cover Armor was the best way for Li Yunmu to spend a large amount of ability points which he had accumulated recently.
Not only could he cultivate this technique himself, as long as he had sufficient space elements, he could even make cultivation relaying globe to increase the strength of his ape gods by teaching them this limit breaking method.
At this moment, Li Yunmu felt that Zheng Quan was just a fool with no eyes. Since his group's physical bodies weren't powerful, he didn't value this manuscript much and easily gave it to Li Yunmu to rope him in.
If they were to learn its true worth in the future, then heaven only knew what sort of reactions they would have.
"It's good, there's still some time left before Zheng Quan and the rest will be done with their preparations. This period of time is sufficient to increase my strength to the next level."
In a split second, Li Yunmu carefully planned out his next steps. In the upcoming days, not only did he cultivate the Cross Cover Armor, but also refined croton. He planned to accumulate enough life points before leaving to get his hands on a method to strengthen his flux points.
