Yang Fei is not as optimistic as Zhou Zhi, because with his previous experience, as well as the feeling of holding the more than 20-meter big mouse just now, if you combine the feelings, it is estimated that this time it will not be able to kill the big mouse, but it will definitely be able to seriously injure it.

Yang Fei, who has some rich combat experience, is very sensitive in combat, and is very good, he followed the big mouse in the air and landed first, and only began to slow down when he was about to land, and at the same time gathered the only little true yuan power left in his body, turning into a streamer and following the big mouse.

"Boom!"

An incomparably loud sound came out, and the huge mouse fell to the ground, Yang Fei, who was flying in the air, did not feel the tremor, but the dust that rose made him frown slightly, and the people on the ground were different, all of them were crooked, even Zhou Zhi, who was in the underground command post, and it felt like an earthquake had occurred.

The golden streamer didn't waste a moment's time, and the moment the giant mouse hit the ground, it began to slash at it. Falling from a height of 10,000 meters, even if it is a mutant beast, a specially evolved existence, it is impossible to withstand it, all the bones on its body have been broken, and all its internal organs have also been shattered, but it has not died yet, because the evolution crystal that is the source of its life is still there.

Although it is not dead yet, if it can find a safe place to cultivate, it may even recover, but it has no chance, Yang Fei's last true yuan power turned into a flying sword, wanton destruction in its body, but perhaps because it is too tired, this destruction looks a little weak.

Far away on the wall of the safety zone thousands of kilometers away, a thin figure appeared, it was Duo'er after handing over Liu Yang to a few people, her divine sense could easily observe the situation over there, when she saw the crumbling Yang Fei, and the weak True Yuan Sword, she couldn't help frowning, and then also spit out a golden True Yuan Force, but did not let this True Yuan Force fly away, but left it to wander around her fingertips a few times, becoming more and more condensed, and then she threw it out with a snap of her fingers, and at the same time she quickly flew to Yang Fei's side, Carried him back.

The condensed True Yuan Transformation Sword, like an ordinary golden needle, quickly shuttled through the body of the big mouse, and after a few seconds, the big mouse stopped struggling. It's completely dead, because its evolution crystal was shattered by Doer!

Everyone cheered, and the troops inside and outside the safe zone who were involved in the battle first began to cheer, so that those managers, and then ordinary survivors, everyone was excited, they overcame, they blocked!

In the midst of these cheers, Dol did not have the opportunity to look at them with respect, but moved the three people who were all unconscious to a room and began to heal them.

She first checked Yang Fei and Liu Yang's injuries, and found that she was almost the same as she thought in her heart, they were just too tired, so she breathed a sigh of relief, she went to check Jiang Shiyu's situation again, and soon frowned, and found that Jiang Shiyu's injuries were too serious.

"How could it hurt so badly?" Duo'er hurriedly used her true yuan power to repair Jiang Shiyu's injuries. Through the observation of True Yuan Force and Divine Sense, Duo'er found that Jiang Shiyu's body was already full of holes, which was not described like this, but the meridians in the body!

As such a powerful evolutionary, Jiang Shiyu should have been repairing her body even when she was sleeping, but now the internal force in her body not only can't repair herself, but is constantly losing because of the thousands of holes in her meridians!

Duo'er looked at the henchmen sent by Zhou Zhi angrily, and said sharply: "What the hell are you doing!" She's hurt so badly, you're actually there."

It was an officer under Zhou Zhi who was yelled at by Duo'er, he was silent for a moment, and said: "We have nothing to do before you come, the safe zone has been able to survive until now, all rely on her, if there is a way to save it, how can we be?"

Duo'er looked at this person hatefully, but she couldn't blame anything anymore, because what he said was right, he was unreasonable, but how did Sister Shiyu get hurt? Why is the external injury not obvious, but the meridians that store internal force have become like this? Even the dantian was torn apart, and the internal force was only a fraction of its original strength.

"Brother Zhou asked me to come over. Ask me what you need, the security zone will do everything to do it, and when will you be able to recover your combat strength" The soldier gritted his teeth and asked, it is said that seeing the current scene, the little girl's three relatives and comrades are in a coma, he shouldn't have asked that, but the reality is that although he killed a fourth-order mutant beast, there are still two within the range of the security zone, although cruel, he has to ask.

Duo'er was silent for a moment when she heard this, knowing that she shouldn't be angry with this person, because it wasn't caused by him, and when her brother rescued her, there were also soldiers from this safe zone involved, so she should be grateful.

"Please tell Uncle Zhou, it's okay to have me in the safe zone, brother, the reason why they are in a coma is because they encountered a lot on the road and they asked me to retain my strength, just to fulfill the promise I made." Duo'er said seriously.

The soldier also looked at Duo'er, he was a little skeptical about Duo'er's words, although he saw her flying in the air just now, and the ability to transform the true yuan sword, but such an eleven-year-old girl, saying such a thing still makes people have to be skeptical.

Duo'er naturally saw this soldier's thoughts, and she said with a flat expression: "Don't doubt my strength, in this world, except for my brother, I am the strongest human being, and the fourth-order mutant beasts that died in my hands are no less than five." ”

The soldier left, and although he didn't know why, when the little girl said that seriously, he really believed it. Now although the safe zone is temporarily victorious, it is still facing a huge crisis, and there are still two fourth-order mutant beasts in the hunting range, which will accommodate the safe zone, if it wasn't for Jiang Shiyu's guidance at any cost a few days ago, the safe zone is probably gone.

Duo'er stuffed a piece of evolution crystal for each of Yang Fei and the two, and then carefully began to study Jiang Shiyu's injury: "According to the meaning of the soldier just now, before we came, Sister Shiyu was responsible for fighting those guys, but my sister hasn't married yet?" How can you confront or attract these guys? Could it be said? She checked Jiang Shiyu's meridians again, and finally found the problem, Jiang Shiyu probably created some kind of method to temporarily improve her strength, but she seriously injured her body.

"Fortunately, I'm already nuanced enough" Duo'er muttered to herself in an inaudible voice, her use of True Yuan Power is to some extent higher than Yang Fei, just like the same True Yuan Sword just now, her sword can be thin enough, so the penetration is much stronger than Yang Fei's, and now her True Yuan Power is more suitable for treating Jiang Shiyu.
