The location of the cause of formation of the blood spar. Although it is an ore-like material, it is actually just a crystallization of an unknown change in the blood in the body after the organism dies.

The method of obtaining blood spar is more troublesome, and it must be collected with special tools. Moreover, the degree of coagulation of the blood spar also determines whether the mining is successful, and the blood spar that does not meet the standard will be broken during the mining process.

There seems to be a large amount of blood spar in this lair, but it will not take less time to obtain 20 blood spar. The three of Yu Tu can only increase their speed as much as possible, hoping to complete the task before the master returns here. If there is no need, Yu Tu and the others are unwilling to fight the boss.

But things backfired. It took them nearly an hour to collect enough blood spar. And the owner here has already rushed back. From a distance, I found Yu Tu and others tossing in their lair, and after a roar, they rushed over.

A large number of dry bones were washed away due to the impact of the boss and flew into the air.

The three of Yu Tu avoided the impact in time, but they were also separated by the boss. Yu Tu, who is closest to the boss, narrowed his eyes and looked at the boss in front of him.

This monster lord is completely an enlarged fear lizard. It's just that there are a lot of whiskers on the neck, the whole is black, and there are hideous bones on the chest and abdomen, which protect the chest cavity. There is a fin more than three meters high on the back, which has a strange pattern like a human face.

Dread the lizard. Ninety level boss. After seeing the monster's attributes, Yu Tu breathed a sigh of relief. It is the enemy they can solve.

But Yu Mu launched the attack first, covered by the sun's fire, and launched the invitation to death, jumping directly to the boss's head, suppressing the boss on the ground.

Because of the boss's body structure, after being pressed to the ground, the two limbs that acted as hands and feet were constantly struggling, but because of the existence of withered bones, he would be unable to get up for a while.

Of course, Yu Mu did not do it alone. With Yumu's physique, it is impossible to put a monster more than ten meters long on the ground and unable to get up. Just adding a heavyweight vine giant is not the same.

After successfully reaching the sixth level, the vine giant body that Yu Shuang summoned finally changed. The height has reached eight meters. There are two more skills. One is photosynthesis, in the battle, always maintain a state of recovery. The other is the hand of the vine. It is also a skill currently being used by giants.

Dozens of tough vines came out of the vine giant's wrist, and firmly bound the boss's wrist and tail. Yu Shuang also commanded the vine giant and gave the boss a cross lock.

In this case, the boss really has no means to resist. Beaten throughout. Can not attack Yu Mu above his head. The only tail that can move can only hit the vine giant in the armor of thorns.

Yu Shuang and Yu Tu both stood in a safe position and cooperated with their pets for stress-free output.

Finally, the boss got his first outbreak. The hot flame spurted from its mouth, directly covering the area where Yu Tu was located.

But the very exaggerated and obvious forward shaking movement made Yu Tu a step away from the distance, without any harm at all.

After the eruption, the dread lizard wailed again and entered the point of passive beating.

In the middle, it is not that it has not broken free from the shackles of the vine giant. But after that, Ivan's flames bound, Yu Shuang's all things growing in addition to Yumu's death hammer, multiple control effects made it dizzy. When he woke up, the vine giant had completed the fixation again.

Both the second and third bursts strengthened the bones outside the body, as well as enhanced jet flames. But none of these can help it get rid of its shackles.

Forty minutes later, the dread lizard ushered in its last eruption. This time, a terrifying black flame ignited on its body. Realizing that something was wrong, Yu Mu left the attack range in time.

The bulky vine giant is not so lucky. The flames swallowed the giant vine directly, and then the body of the entire dread monster lizard began to change.

The flame not only helped it resolve the constraints on its body, it was also devouring its body. What came out of its mouth was not a threatening roar, but a painful neigh.

The strange change left the three of Yu Tu puzzled. Trial attacks can't cause any damage to the boss in the flame. The three of them could only distance themselves cautiously, waiting for the end of the boss change.

This process lasted a full five minutes. Has completely broken away from the extent of the boss outbreak.

The three of Yu Tu witnessed all the changes of the boss.

The flesh and blood on his body was burned into coke and attached to the bones. The internal organs are directly burned out. The dry skin was like rags, wrapped around the bones, and the whole monster became extremely hideous. The bare bones became more hideous and terrifying on the original basis. Something like dark red plant roots spread out from the position of the monster's heart, connecting all the bones together.

When the flames dissipated, the dread lizard had completely transformed into a skeleton monster. The only thing that can be counted as flesh and blood is the shriveled heart on its body.

And that heart, like a disgusting tumor, the roots drilled out of it firmly bound the skeleton.

Yu Tu and Yu Shuang are no strangers to that thing. It was the same thing that I had encountered before in the forest near the Secret Realm of Ancient Trees when destroying the mutant Goblin Village. Just like the heart of the abyss turned into a dead soul.

Yu Tu and Yu Shuang looked at each other, and they both understood the meaning. The power of the undead had already penetrated below this forging mountain city. Although it was not clear how the opponent did it, Dushan City was already very dangerous now.

Although the mutated dread monster lizard has improved attributes, it also has a lot of weaknesses. But it also lost the ability of long-range strikes and magic attacks. Pure physical damage is not so terrible to the vine giant.

The fear lizard, which had a small amount of blood, was completely defeated in less than five minutes. The dead body turned into a pile of scattered dead bones.

After picking up the drop, Yu Tu frowned.

Yu Shuang came over and asked, "Why didn't I see the heart?"

"I don't know. Just now the boss made too much action after his death, and the position of his heart was covered. This thing shouldn't be able to run, right?"

Yu Mu asked: "What are you talking about?"

After Yu Tu briefly talked about the heart they encountered before, Yu Mu immediately made a judgment.

"It should have run away. A large part of these parasitic things have the ability to change the host. Among them, some have the ability to act on their own. It is convenient to change the host."

Yu Tu thought for a while and said, "Go back first. Tell the people in Dushancheng about this. We don't have the ability to manage so many things."
