Thousands of birds and mutant beasts flew in, which immediately attracted Lei Zheng's attention, and he asked the snipers on the city wall to pay attention to concealment and kill, and at the same time immediately informed Shen Yan of this situation.

The battle inside the base became more and more intense, and Shen Yan had already killed all over the body at this moment, and the whole was bloody. The momentum of the mutant beast group is getting stronger and stronger, even he feels the pressure at the moment, and retreats while fighting.

He didn't pay attention to the attack of a thousand bird mutant beasts, there were few of them, and he believed that the snipers on the city walls would be able to cope with it. And his only main task at this moment is to kill, kill all the mutant beasts that can be seen in front of him. Because in the face of pressure, he has already touched the slightest sign of breakthrough.

A mutant cow appeared in front of him, a mutant cow wearing scale armor, and this mutant cow was twice the size of the other mutant cows. Level 4, this is a mutant cow whose strength has definitely reached level 4. The most attractive thing about the fourth-level mutant cow is its scale armor, and the long tail behind its buttocks, in the process of its charge, many bullets hit its body, but those bullets only sparked a spark on it, and it had no effect at all. The moment that tail rushed close to Shen Yan, it slammed towards him.

Relying on the scale armor on its body, this monster is like entering a no-man's land, rampant, and even in the process of its charge, because of the push of its companions, it will use its strong body to knock its companions into the air.

"Moo!" With a deep roar, the mutant cow's thick tail slammed towards Shen Yan. After discovering the peculiarity of the other party, Shen Yan had already been lifting the other party, and when he saw his tail smashing it, he hurriedly dodged.

"Damn, this beast's tail can still grow longer and bend!"

Shen Yan, who was dodging, was shocked in his heart, because it was obvious that he felt that he should have dodged this blow with a sliding step, but the other party's tail was good out of thin air, and it suddenly extended its crutch, and finally smashed it on his body.

"Boom!" The huge power of the mutated oxtail instantly spread throughout Shen Yan's body, and Shen Yan only felt a hot pain in his back when he was pumped, and the whole person also stumbled violently at the same time as the oxtail was pumped, and his steps were disordered.

"Roar!"

Seeing this, the other mutant beasts behind the mutant cow raised their heads and roared, and in this roar, the mutant beast group seemed to have been beaten with chicken blood, and they were excited, and the speed under the hooves increased sharply, rushing towards Shen Yan, towards Guan Feng and them, and towards the entire defense line.

The whole process feels slow to describe, but it's actually happening in the blink of an eye.

Shen Yan's pace was out of order, and he didn't have time to dodge the dense charge of the mutant beast group, and suddenly, a pair of dragon teeth in his hand suddenly waved, and two cold lights appeared, quickly slashing at a mutant dog rushing towards him.

Snort! Wow!

The sharp blades slashed through the body of the mutant dog one after another, and the mutant dog, whose expression was full of excitement, suddenly darkened his eyes, and his body was directly cut into three pieces by the dragon's teeth, and the internal organs in his body were directly sprinkled to the ground after landing.

"!" The recent crisis had just been resolved, but the mutant cow immediately launched a second attack after winning the first blow, and this time it rushed towards Shen Yan as a whole, causing Shen Yan to scold.

The head of the mutant cow was low, and the two sharp horns emitted a cold light, and in a blink of an eye, they came to Shen Yan's body.

"Hey!"

The whole process was too fast, all of this was just because of Shen Yan's confusion just now, which caused him to take one wrong step after another under the siege of mutant beasts, and he couldn't keep up with the other party's speed. In desperation, he suddenly stomped his feet and jumped up, jumped into the air at the moment when the sharp horns of the mutant cow stabbed him, and jumped onto the back of the mutant cow.

"Die!" The first time he jumped on the back of the cow, Shen Yan roared, and hurriedly stabbed out the dragon tooth in his hand at the back of the mutant cow's neck. But at this moment, a ray of golden light suddenly emerged from the tip of the dragon's tooth under a stab, as if it was a sword qi, and before the dragon's tooth pierced into the mutant cow's stamina, it had already taken the lead in submerging the mutant cow's stamina.

"Well, this ...... Just now it was ......"

Shen Yan was slightly stunned, the confusion of his steps made him fall into a crisis just now, at that moment, his whole person was highly concentrated, killing, dodging, jumping, and stabbing in one go. It can be said that there was one thought in his heart at that time, that is, to solve the mutant cow in front of him.

"Moo!" With a terrible howl, blood gushed out of the thumb-sized hole that appeared in the hind part of the mutant cow.

The miserable howl of the mutant cow brought Shen Yan back to his senses, and he hurriedly jumped up on the back of the cow and pounced on the other mutant beast. There was no way, the crisis just now affected the coherence of his killing, so that his body was completely surrounded and clogged by mutant beasts, and he couldn't land on the ground at all, so he could only risk going through the back of the mutant beast to the building not far away.

Fortunately, he was extremely fast, and he was only less than ten meters away from the target building, and a few agile relays quickly climbed to the second floor of the building. But just when he breathed a sigh of relief in his heart, his body suddenly softened and he fell to the ground, as if the strength of his body had been completely exhausted at this moment.

The danger that Shen Yan faced before, Guan Feng and the others had seen it with their own eyes, but at that time, they had already retreated to twenty meters away, and even if they wanted to rescue, it was too late. Seeing that Shen Yan had fled all the way to the building on the back of the mutant beasts, he couldn't help but breathe a sigh of relief while admiring in his heart.

"Mira, how do I feel like I'm completely out of strength? Also, what was that golden light emitted from the dragon's teeth just now? The sudden weakness of his body made Shen Yan feel horrified, and as soon as he was safe, he hurriedly asked Mira.

"Congratulations to the master, the master has just triggered the star energy in his body under a high degree of mental concentration. The master's body is weak now, and it is also because after the star energy is urged to attack, the consumption is too great, it is like losing strength, and he just needs to take a rest! Mira was quick to explain.

"This ...... How is this possible, I can't even perceive the star energy in my body, how is it possible...... Hey...... This is? Hearing Mira's explanation, Shen Yan was shocked and wanted to question, but soon he discovered a strange thing, he actually felt some kind of filamentous heat flow around his body, which was slowly flowing into his body, and in the process of these heat flows, he actually felt that his physical strength was slowly recovering.

Just when Shen Yan felt this change in his body, Mira's voice sounded at the right time: "Master, when Mira reaches the sixth level of strengthening, she will be able to feel the star energy between heaven and earth, and then as the level continues to improve, this perception ability will become stronger and stronger." And Mira is now parasitic in the master's body, and its own function is to transform the master's body. For example, feeding back to increase the master's strengthening level, residing the brain to open up the master's brain domain to improve mental power, and the additional effect of bioradar, all of which are the effects of Mira's parasitism! Of course, this sensing star energy between heaven and earth will not be an exception! Otherwise, Mira wouldn't have been transformed into what she is now, and there wouldn't be so many people in the universe who wanted to capture Mira! ”

Mira's explanation made Shen Yan understand but a little confused, he already knew the various enhancements in Mira's mouth, but even if he could perceive star energy, it would be impossible to force star energy out at once!

As early as when the ruins of the alien warehouse were discovered, that Yantong used the golden knife to use a certain method to force out a golden light. At that time, Shen Yan asked Mira what was going on, but the other party clearly told him that it was because there was star energy in the golden knife, and the reason why Yan Tong was able to make the golden knife emit golden light was mainly because he had mastered the method of triggering, but it could not really trigger itself, it was just a passive use.

Mira sensed some thoughts in Shen Yan's heart, and sighed helplessly: "It's a pity that the master didn't accept the Xuanyuan inheritance, and Mila didn't accept the information inheritance of the starship wisdom brain, otherwise...... I don't know anything about these Miras now. If you have a method of cultivating star energy now, you don't have to be so confused. ”

"It's inheritance again!" Shen Yan muttered in his heart, but after thinking about it, this was indeed the case. Now his battle can be said to be completely based on his body itself, that is, speed, strength, and reactions. In addition, there are some fighting techniques that he learned from Guan Feng, but as his strengthening level gets higher and higher, there will always be a feeling that he can't use his full strength in battle.

And just now, after suddenly emitting that golden light, although it brought him endless exhaustion, it made him feel extremely happy. Even now, the slightest stream of heat continues to pour into his body, which makes his body feel extremely comfortable, and there is a feeling of nectar on the dry earth for a long time, which is extremely wonderful.

The exchange of consciousness was already very fast, and in only a few seconds, Shen Yan got up from the ground and walked all the way to the window. On the street outside the building, the mutant beast group had already rushed crazy at this moment, Guan Feng and his party had retreated to two hundred meters away, and the nine of them had completely formed a tight defensive formation. The two thousand elite wolf warriors are also a little precarious at the moment, the number of wounded is increasing, although there are no deaths, but the increase in the number of wounded has made the combat power of the elite wolf warriors more and more weak. In addition, even those wolf warriors who have the support of the defensive line are in many dangers at this moment, and many agile mutant beasts have rushed into several surrounding buildings, obviously to attack those warrior wolves who rely on the buildings to fight.

"No, the impact momentum of the mutant herd has taken shape, and it will be more and more difficult for us to defend if we continue like this." Seeing such a scene, Shen Yan immediately issued an order to the thunder array through the communicator, asking it to close the east city gate.

ps: It's still one chapter today, alas, this time I owe four more chapters. Anyway, I suddenly didn't have time for a day, and I was really a little uncomfortable, and the writing was somewhat starting to get stuck now, which was really depressing! Owe it, anyway, the old wolf remembers it one by one, and he will definitely make up for it. Sweat...... Clench your fists!
