Song Ren was thrown into the endless deathly aura, and he and the sword became one, transforming into a purple sword light that rushed towards Long Yu.
However, in the surrounding death energy, bone dragons continuously spewed out death energy beams, which continuously attacked the purple sword light, greatly weakening its speed and making it difficult to catch up with Long Yu.
Just after a few breaths, Long Yu finally stepped into a place where the aura of death was even more intense.
This place is the center and deepest layer of the Dragon Bone Burial Ground!
The concentration of death energy here is at least a hundred times higher than that of the death energy outside the Dragon Burial Ground. Even Long Yu, who came here, began to be eroded by the death energy, not to mention others.
Song Rentou followed Long Yu closely and when he stepped in here, he found that he needed to spend half of his strength to resist the erosion of the death energy. His face suddenly became extremely gloomy.
He came out of the state of unity between man and sword, probably knowing that he could not catch up with Long Yu. At this desperate moment, he shouted at Long Yu: "How about we talk? I will not chase you anymore, and you don't have to kill me. After I leave safely, I can teach you the method of practicing the infinite martial art, Purple Bat Reflection. How about it?"
This guy actually started to use the training method of endless martial arts to tempt Long Yu, but Long Yu was not fooled at all.
He was indeed looking forward to the endless-level martial arts, but forget about the purple bat reflection. Long Yu could feel that the purple lightning that attacked him before contained the power of immortal purple blood.
If Long Yu guessed correctly, even if he got the training method of the endless-level martial arts skill Purple Bat Reflection, he would not be able to practice it because he did not practice the martial arts secret skill Immortal Purple Blood.
Simply put, Purple Bat Reflection should be a martial art that matches the Immortal Purple Blood. Even if other people get the practice method of Purple Bat Reflection, it is definitely impossible for them to practice it successfully.
However, since the other party wanted to negotiate terms, Long Yu was happy to have a good fight with him and find an opportunity to kill him completely.
So Long Yu laughed, slowed down his pace a little, and said directly: "Purple Bat Reflection, I don't really want to practice, but I want to practice the Undead Purple Blood. If you tell me, I will let you go, how about it?"
"Can."
There was a hint of surprise in Song Rentou's eyes, as if he was surprised that Long Yu could withstand the temptation of endless martial arts, and calmly asked him for the Immortal Purple Blood.
He was puzzled, but he just thought that Long Yu had never seen the world and didn't know the value of endless martial arts... Even in the outer space, endless martial arts can be said to be the treasure of every tribe. For example, the Purple Brahma tribe only has the endless martial arts of Purple Bat Reflection.
"Well, I will record the cultivation methods of Immortal Purple Blood and Purple Bat Reflection in this jade slip and place it where I am. Then, you fly outside the Bone Burial Dragon Field, and I will chase you out. When I reach the outer layer, I will let you go, and you can also come back to get the jade slip. What do you think?"
Song Rentou took out a jade slip and suggested to Long Yu.
Long Yu narrowed his eyes. The other party's idea seemed to be good, but in fact it was quite disadvantageous to Long Yu. First of all, Long Yu could not be sure whether the jade slip really recorded the method of practicing the Immortal Purple Blood. Secondly, it was impossible for Long Yu to return to the outer layer of the Dragon Burial Field while being chased by the other party. That would be purely seeking death.
Although Long Yu was able to escape to the depths of the Dragon Burial Field while being chased by eight people, that was because the other party was not prepared. If it happened again, Long Yu was not sure if he could return here alive.
Furthermore, as a genius of the Zifan tribe, Song Rentou must attach great importance to the Immortal Purple Blood and the Purple Bat Reflection. If he gives them to other people so easily, he will most likely be severely punished when he returns, or even sentenced to death!
After all, the Immortal Purple Blood and the Purple Bat Reflection are the treasures of the Zifan tribe. How can they be leaked so easily
If this is the case, Song Rentou either does not intend to give these two items to Long Yu, or he is sure that he can kill Long Yu.
"Okay, you should first record the Immortal Purple Blood and the Purple Bat's Reflection into the jade slip."
Long Yu nodded, with a greedy look in his eyes. He was trying to confuse Song Rentou and make him believe that he was greedy.
"That makes it easier to talk."
Song Rentou laughed, took out a jade slip and began to write something into it.
Song Rentou was the most defenseless at this time, because he was sure that Long Yu would not touch him before he completely wrote down the cultivation methods of Immortal Purple Blood and Purple Bat Reflection. After all, once he died, these two cultivation methods would be gone!
But he didn't expect that Long Yu never wanted these two things from the beginning to the end.
If it was given for free, Long Yu would not refuse, but, is it possible
The other party used these two things as bait, but their goal was to take Long Yu's life!
So, while the other party was tampering with the jade slip, Long Yu had already mobilized the bone dragons in the dead air around him, and even let a dozen bone dragons surround this place silently.
These bone dragons are all condensed from deep-seated death energy, and each one is at the level of a seven-star emperor!
"Almost... Kill!"
Long Yu looked at Song Rentou who was still fiddling with the jade slip, with greed still in his eyes, but he had already moved his mind and controlled those seven-star emperor-level bone dragons to bombard Song Rentou!
More than ten deathly light pillars suddenly came crashing down from all directions, instantly submerging Song Rentou in them!
Such an unexpected situation left Song Rentou completely stunned.
How could this be the case
He hadn't even finished writing the cultivation methods for the Immortal Purple Blood and the Purple Bat Reflection, but this guy had already started? This was unscientific! Could it be that he had no idea about the secrets of martial arts and the infinite martial arts
Surrounded by an endless vortex of death, Song Rentou glanced at Long Yu, only to find a teasing look in Long Yu's eyes. It was obvious that he was laughing at Song Rentou for being too stupid.
In this calculation, it is obvious that Long Yu is better and has the upper hand!
The price of failure is death.
Song Rentou was not stupid, and the method he came up with was a surefire way to kill Long Yu. However, he had not expected that Long Yu had no greed in his heart at all.
Without greed, the bait he threw out was completely ineffective, and it could even be said that he was tying himself up in knots, causing himself to die faster at the hands of Long Yu.
When Song Rentou was swallowed by the vortex of death and no trace of his body remained, the jade slip he was fiddling with in his hand suddenly exploded, and a burst of purple light burst out!
"Sure enough, he is playing tricks."
Seeing this, Long Yu sneered.
The reason why the jade slip exploded must be because Song Rentou never thought of recording the two cultivation methods in it. Instead, he input his own power into it. Once Long Yu wanted to check it, the power would explode directly. In that case, Long Yu would die without Song Rentou doing anything himself.
It’s a pity that Song Rentou still doesn’t know Long Yu well enough. If he knew Long Yu’s character, he would know that Long Yu would never suffer any loss in any calculations.
For Long Yu, if he had a choice, he would never gamble with his life. Since he could kill the other person, why not
If Song Rentou was facing someone else, he might have succeeded, but unfortunately he was facing Long Yu.
Song Rentou's entire body turned into death energy and was sucked into the vortex of death energy. The jade slip in his hand also exploded directly. There was nothing recorded in it, but it only condensed unstable power.
After dealing with the last Song Rentou, Long Yu turned around and flew towards the center of the deep dragon burial ground.
After a stalemate chase, Long Yu was finally about to reap the rewards. If he guessed correctly, the Nine Nether Dragon Emperor must have prepared a lot of things in the center of the Dragon Burial Ground.
As Long Yu continued to go deeper, the death energy around him became more and more dense. Although the 42% of the Nine Nether Seal he mastered could help him absorb most of the death energy, there was still a trace of death energy that began to erode his entire body.
Long Yu had no choice but to condense the death energy around him and rely on the powerful death realm body training to resist the erosion of the death energy. For the time being, there would not be any big problems. However, it seems that before Long Yu has mastered the Nine Nether Seal 100%, he will not be able to freely enter and exit the deepest part of the Dragon Burial Field.
The deeper Long Yu flew, the more he felt the extremely dense death energy, as well as increasingly powerful bone dragons appearing in the death energy around him.
Among these bone dragons, beings at the level of dominating secret realms began to appear. It seemed that there was a small world inside the body of each bone dragon, but this small world had been shattered.
Through the information conveyed by the Nine Nether Seal, Long Yu inexplicably knew that a bone dragon like this one that dominated the secret realm could not be condensed at will, but required a broken small world to condense.
Whenever the Nine Nether Dragon Emperor kills an opponent who dominates the secret realm, he can absorb the opponent's broken small world and then integrate it into the infinite death energy, thus condensing a bone dragon of the level of dominating the secret realm.
If Song Rentou had chased to this place just now, these bone dragons that dominated the secret realm would have killed him with one bite, leaving him with no room for resistance at all.
However, if Song Rentou came here, there would be no need for the Bone Dragon to take action, because the thick death aura nearby was enough to be fatal. A strong man at the level of Seven-Star Emperor could no longer resist such a deep and thick death aura. When he came here, his whole body would be eroded by the death aura, gradually corroded, and eventually become a part of the death aura.
Even Long Yu's body began to be gradually corroded by the death energy, and he knew that he didn't have much time left.
Fortunately, the very center of the entire Dragon Burial Ground was finally in sight. Long Yu flew forward for less than a hundred miles and arrived at the core of the Dragon Burial Ground.
He saw at a glance that there were some things floating in the densest death energy in the center. These should be the things left behind by the Nine Nether Dragon Emperor!
