The experimental subject piled up building blocks on No. 0, like layers of rough-looking armor, pressing it completely on the bottom layer and protecting it. Cassia wanted to run behind them, but she had the idea of ​​turning around. The gray-brown waves had swept forward. In the blink of an eye, the waves of twisting space were directly over them, and the next moment they had gone dozens of meters away. It was not until it walked nearly a thousand meters that it completely lost its power and gradually dissipated.

Within this huge fan-shaped range, the dead leaves were completely lost. The trembling ground calmed down, as if a layer of frosted black paint was sprayed, which was even and beautifully twisted and flat. The roots of the ancient tree and the exposed rhizomes all lost their bark, and the sap quickly flowed over the surrounding ground.

"Dong!" An ancient tree was shaking violently and tilting towards a center. After the sound wave attack just now, the three-headed dragon almost rushed over, and the ground exploded under the pressure of three huge claws. Large pieces of extremely powerful mud and stones splashed, hitting the trunk of the tree could break the fist-sized pit.

Seeing a shadow flashing past, instantly pulling the distance away and avoiding the attack, Sasser, Hainuoyi and others were not surprised. Hainuoyi and another dragon knight continued to pursue. The next moment, Sasser drove the dragon to extend his claws to grab the smoke generated by the slap, and took out the experimental body with blood flowing out. Number Zero drilled out of a pile of experimental body and jumped to Sasser. The dragon put down a pile of experimental body, and some people on the inner layer immediately got up, not caring about the injuries on his body, and began to chase. Sasser immediately turned his direction and chased Cassia with a light blue all over his body.

"How is it?" As the dragon ran thunderously, Sasser did not forget to care about the current situation of Zero. He was the guarantee of himself and Hainuoyi and others. If Cassia approached the subsequent attack, he would still rely on Zero to carry out emergency restraint. The dragon's huge body was destined to be difficult for them to deal with flexible and small enemies.

Zero exhaled a long breath, and the crackling sound of his body moved made several cracks on his blood-red fusion scales continue to crack a lot.

"It's not a big problem." Zero answered calmly, looking at Cassia who was avoiding attacks from Hainuoyi and others in front of him, and her cross pupils contracted again. "My own injury is not very serious, which means that Cassia's condition is roughly similar to mine. Even though he does not have the protection of the experimental subject, his body is even more weird than me. You can't be fooled by his performance." As he spoke, the cracks on the fused scales of his body had closed like a wound, as smooth as before, and there was no trace of cracking.

"Even if we separate it, we will reach the first step of the plan. Let's see how long we can take." Without continuing Zero's words, chasing Shanghai Noyi and others, Sasser also joined the battle. Zero jumped off the back of the dragon's spine and went to Kemishul and others who had walked an arc route.

Everyone observed on the side. In the battle of the Dragon Knight, Zero often had no chance to intervene. The dragon not only had a huge body, but also did not seem extremely clumsy in its own flexibility. Because of its huge power, the threat of each attack was comparable to that of a sniper firearm aimed at the head. If it was affected once, it would cause a chain reaction.

Komishul and others used guns and cannons to assist in shooting, further compressing Cassia's range of activity space and forcing him to reveal fatal flaws as much as possible. Zero then rested behind them, and stepped up time to recover their physical injuries. The attack launched by the three-headed dragons, although the experimental subject helped it block the huge impact, the vibration it carried could ignore the experimental subject that surrounded it and could only rely on the strength of its body to resist.

There are only less than fifteen experimental subjects left. Number Zero stared at them who were dodging by instinct between the attacks of the three dragons. For some reason, he always felt that no matter whenever he seemed to have the advantage, but after careful consideration, he could always find that compared with the target Cassia, the one who suffered the most losses was always his own side.

The fifty experimental subjects only have the current number, and most of them are injured, and the threat is reduced by more than half. Faced with the target, this number cannot play any role. The other members in the team have not decreased in number, but Zero knows that these members have no substantial effect than the experimental subjects. As long as they lose their own or the Dragon Knight's limit, their death is only a matter of time and speed.

At this moment, more than 200 people evacuated went to the entrance of the cave where Foster was located and defended two or three thousand meters away, which helped Foster relieve some of the pressure.

When Saswa observed No. 0, he issued an order to keep the people around him away. It is always a hidden danger to have team members around him. Although it is difficult for Casia, who is surrounded by three giant dragons, is difficult to rush out, Sasser and others have no way to let the dragon capture Casia, who is close to the limit at this stage. Zero needs to be around all the time, not only does he need to give Casia pressure at any time, but also needs him to create a link in the chain to ensure that Casia and everyone between them will not use breath or dragon breath easily.

The three-headed dragon sported its wings from time to time, dispersing the smoke that spread. The armor on their bodies was full of corrosion marks, and pungent black and gray smoke continued to emerge. The dragon of Hainoy had removed the red-like heat device on the two sharp claws, and the corrosion of Cassia's blood directly made them useless.

The light green blood on Cassia's body was roughly thrown away by him during the battle. At this time, he almost stopped attacking, but continued to avoid it through speed, his own flexibility, and the interference between the three-headed dragons.

The high-frequency sound waves were superimposed at the next moment. Cassia wanted to get close to the entrance of the cave, but was completely blocked by Sassel and the others, so she could not move forward any further. It was only about two thousand meters away from the entrance of the cave. Cassia, Sassel and others could see the charred area after being swept by the dragon breath. The sunlight that was getting closer to noon shone it was extremely bright.

Feeling the high-frequency sound waves spreading, Mishul, Jeremy and others looked at the entrance of the cave. At this moment, the situation that should have relaxed them a little, made them under greater pressure in another form. Their spirit became tense, but Mishul and others seemed very passive in front of this sense of unknown feeling.

"Pay attention to the hole! Captain Sasser, if the situation remains stalemate, you can use the red mercury bomb when necessary!" Kemishul reminded in the communication that she sometimes even thinks that the target emits sound wave pulses, which are deliberately used to distract them.

"Well, oh, oh,"

At the same time, Cassie Hei was moving forward. Not only was the high-frequency sound waves captured, it also sensed the vibration transmitted from the ground. No longer moving forward rapidly, Cassie Hei had a little impression of this place. Because it was not far from the entrance and exit of the cave, the place he had just passed was the cavity it used to collect materials for the "Stone Gate".
