The process of escape and pursuit continued, and the strange prison wolf dragon didn't know what it was doing, and stared at the dinosaur. And although the dinosaur has been running away, it is not a good-tempered master, and every time it happens to have a full meal, it will always reflexively attack when the Prison Wolf Dragon stops to rest.

The combat power of a well-fed dinosaur is naturally not something that a prison wolf dragon can resist, but in the face of an opponent who can recover quickly no matter how great the trauma is, the only thing the dinosaur can do is to continue to escape.

In Shi Leiyin's opinion, the Dinosaurus was actually on the verge of victory once, and the long-lasting dragon-slaying breath had already made the purple-black aura on the Prison Wolf Dragon's body begin to fade, as long as he rushed up to tear apart the body that the Prison Wolf Dragon had just recovered, the purple-black breath would not be able to forcibly reassemble the corpse. However, the dinosaur, which had been breathing for a long time, did not rush forward, but turned around and ran, which made Shi Leiyin very regretful.

However, this regret turned into happiness the next time the two sides fought. Due to the fact that the Prison Wolf Dragon was seriously injured last time, when the two sides fought again, the Prison Wolf Dragon still had a strong purple and black aura on its body, and the wound was constantly recovering. Therefore, Shi Leiyin finally knew why the dinosaur didn't take advantage of the period when the prison wolf dragon was seriously injured and the purple-black aura faded to give the final blow.

An ice rabbit who didn't have time to avoid the two sides of the battle was inadvertently bumped into the purple-black aura beside the prison wolf dragon when he was scared by the warring parties, and the result was only a slight contact, and the ice rabbit immediately rolled on the side with the same purple and black breath, but unlike the hellwolf dragon, although the ice rabbit also became a lot stronger, it lay motionless on the ground after more than ten seconds. The purple-black aura wrapped around the ice rabbit was as strong as when the Hellwolf Dragon was resurrected, but the Ice Rabbit did not stand up again like the Hellwolf Dragon, but turned gray-black all over. When the Prison Wolf Dragon moved, the wind blew away the purple-black aura on the ice rabbit's body, and Shi Leiyin was surprised to find that the ice rabbit itself had also turned into a gray-like thing and was blown away by the wind along with the purple-black aura.

With this verification, Shi Leiyin can be regarded as knowing why the dinosaur did not take the opportunity to attack the seriously injured body of the Hellwolf Dragon. Obviously, that purple-black aura has a great deal of uncertainty, and it may make the contaminated creature become almost immortal like the Hellwolf Dragon in front of it, or it may directly consume the life of the light creature and turn it into a pile of flying ashes. And in either case, the sanity of the creature itself will be significantly affected.

Thinking back to the previous battles, Shi Leiyin noticed that the few contact battles between the Dinosaurus and the Hell Wolf Dragon were all under the condition that the purple-black aura was basically completely converging. And when the purple-black aura permeates and begins to repair the wounds of the Hell Wolf Rex, the Tyrannosaurus will choose to use non-contact attacks such as throwing clods of dirt or slaying the dragon's breath. Obviously, this dinosaur knew that the purple and black aura could not be touched.

Due to the protection of this untouchable purple and black aura, this time the battle was still fruitless. The dinosaur didn't even use the dragon slaying breath, and directly threw out more than a dozen huge clod balls in a row to bury the Prison Wolf Dragon, which had not fully recovered its strength, and then turned around and ran.

With the example of the rabbit, Shi Leiyin also figured out why the dinosaur would choose to stop and fight from time to time when he knew that he could not kill the other party. That purple-black aura will obviously not only repair the bodies of entangled creatures and increase their strength, but also consume a lot of the creature's ** potential. Once the potential is depleted, it will be like the rabbit and will be directly reduced to ashes.

However, Shi Leiyin still doesn't understand, first, what is that purple-black aura? Where did the Prison Wolf Dragon get contaminated from, and secondly, from the example of rabbits, although it can be quickly infected with only a slight contact, but once the contaminated creature dies, if the purple-black gas can't find the host immediately, it will dissipate very quickly in the air, and it does not have highly infectious characteristics like the zombie virus. In the end, although those purple-black breaths will consume a large amount of life ** energy of the entangled creatures, from the rabbit's body, the purple-black breath itself does not get much energy from it, and only a very small part of the energy consumed is converted into a purple-black breath with a higher concentration, and most of it is used by rabbits to release more powerful power.

For Shi Leiyin, although it is his habit to analyze problems, another habit is to throw aside problems that cannot be analyzed and do not concern him. So Shi Leiyin happily put his attention back on himself.

Dinosaurus is not in a good situation now, as a top predatory creature, dinosaur is actually not suitable for long-term running life, especially in the absence of adequate nutritional supplements, and must continue to consume the life energy of the chasing prison wolf dragon, just three days, the body of the dinosaur has been thin at a speed visible to the naked eye. Of course, the reduced fat also gave the dinosaurs a lot of speed and more time to rest.

What Shi Leiyin has to consider now is whether to leave the body of the dinosaur. The erosion of the body of the dinosaur has reached a deep level, and almost eighty percent of the doppelganger's body has completely entered the inside of the dinosaur's wound, and is fusing and absorbing the ** of the part of the dinosaur, and the body left on the outside is almost fused with the skin scale armor. Now unless the dinosaur ripped off this part of the **, it can't stop Shi Leiyin's continued invasion. But the problem is that Shi Leiyin found that as a top-level ancient yasaurus, the ** of the dinosaur also has a strong resistance to erosion, and the deeper it goes, the higher the rejection of the cells against Shi Leiyin's assimilation and erosion. According to this trend, if Shi Leiyin wants to invade the heart like he did before against the sword thorn badger, absorb all the essence and break out of the body, it will take at least a year or two. This time is too long, unless Shi Leiyin uses the main body, and does not care about the possibility of being discovered and invaded by the dinosaurs, and erodes with all his might, this can be completed in a few days. And now the dinosaur** gene obtained by Shi Leiyin is only the heart part that can make blood essence. In other words, if Shi Leiyin is willing to consume a lot of energy, he can already imitate the strength of the dinosaur, of course, the breath of the dragon slayer still can't be released.

In addition to the fact that it takes too long to continue to erode the body of the dinosaur, the Hellwolf Dragon, which has been chasing for unknown purposes, is also a big trouble. Judging from the example of the rabbit and the performance of the dinosaur, sooner or later, the Hellwolf Dragon will be completely destroyed by consuming all the essence of **, but this time is uncertain. The kind of purple-black aura that will consume the essence of the creature**, Shi Leiyin doesn't want to try the taste of being entangled, although now this body is just a perfect doppelganger, but this world is a magical world with magic and souls, and the ghost knows if that purple-black aura will annihilate the soul consciousness, judging from the appearance of the Hell Wolf Dragon, this is really difficult to judge.
