PS: The third update!

Contingency measures, yes, when building the city wall, Shen Yan and they thought about emergency measures to deal with the situation in front of them, and the measures were actually very simple, that is, to open the door and put the enemy inside the base.

The first base has only two gates, east and west, and the gate is built exactly according to the portal of the second base, and the heavy gate of all alloy is five meters thick, and it is difficult to blast it open even with a cannon.

Originally, according to the design, the construction of the inside of the base was completely built after the enemy attacked the base, and the underground civil air defense was expanded to the entire base, and all the buildings on the ground would be built very solidly and connected to each other, even if it was a space separated by a street, if necessary in wartime, a simple overpass would be erected. If the four high walls of the base are four-sided bunker groups, then the buildings inside the base will also become bunker groups after the enemy breaks through in wartime.

Especially on the inside of the gates on both sides, two small urn cities were built, although the whole urn city is only 10,000 square meters in size, but it can be used as a diversion and decompression in wartime. Moreover, when the situation is critical, the inside of the urn city will be instantly filled with fuel and ignite a fire, bringing a buffer time to the defense of the base.

The expansion of the second base not only did not cancel the earlier plan, but made it more perfect. It's just that four months is too short, and the construction of the four city walls has already consumed a lot of manpower and material resources, and the second base has become the focus after the discovery of the warehouse ruins. In the end, only the four walls and three walls of the urn city were completed, and only a small part of the interior construction was carried out.

However, just one urn city is enough for now, and when the time comes, it only needs to open the gate a little and let the mutant beasts outside transfer their targets for diversion. Just like Shen Yan said, why don't you want someone to send meat for nothing, Wengcheng can completely destroy the mutant beast while collecting the corpse of the mutant beast.

Time slowly passed, and the mutant beasts outside the city walls were still attacking frantically, and the corpses were still accumulating. Even if grenades were dropped from time to time on the city walls to blow up the corpses that had been built high above, it only slowed down the accumulation of mutant beast corpses. Seeing this, Lei Zheng no longer cared about it, and directly dispatched two thousand war wolves from other city walls to the East Gate Urn City. At the same time, after receiving the notice, Zhan Tiancheng also quickly organized two thousand wolves to rush over, and they would take on the task of carrying the corpses of mutant beasts in the subsequent battles.

"Captain, what's going on over there?" The corpse blocked the street, and Shen Yan led a hundred elite wolf warriors, and with the assistance of the other four hundred elite wolf warriors upstairs, they quickly eliminated the more than five thousand mutant beasts that were blocked behind. Now the four hundred war wolves on the roof of the building have gone down to the ground to help the war wolves on the ground collect the corpses of mutant beasts.

"The fuel port has been opened, and you can move in three minutes at most!" Guan Feng was quick to respond.

"Okay, everyone retreat to the base, and we'll go capture the mutant beast." Shen Yan hurriedly said when he heard this.

"Catch the mutant beasts, what are these damn beasts caught for, wouldn't it be better to kill them and eat meat directly!" Guan Fenghu responded suspiciously, but he quickly reacted and scolded with a smile: "You little pervert and pervert, you dare to hit the attention of those big guys." However, this attention is good, raising chickens and eating eggs is indeed better than killing chickens and eating meat. ”

"Hehe, hurry up, leave someone to set fire, and the others quickly withdraw!" Shen Yan turned off the communicator in laughter, and with a wave of his hand, he led his wolf into a nearby building.

The size of the mutant beast was one or two times larger than before the disaster, and more than five thousand were really a lot, but this could not withstand the five hundred spatial rings carried by Shen Yan and the five hundred of them.

In the past four months, as Shen Yan cleared out the more than two million zombies in Fengcheng, the star energy of the second-level zombies has greatly increased, and each of them has reached as many as one hundred, not counting those third-level zombies that continue to be promoted due to various circumstances, as well as the results of killing mutant beasts. With an income of nearly 300 million star energy, Mira has been successfully promoted to level seven, and Shen Yan's level has also broken through to level seven in one fell swoop.

Level 6 is a period of transformation of Mira's ability in the process of continuous strengthening, and its bioradar scanning function not only reaches a diameter of 100 meters, but also absorbs star energy between heaven and earth on its own. As for reordering the sequence of crystal atoms, his ability to create storage space has also improved a lot, not to mention that his current level has broken through level seven in one fell swoop?

Moreover, more than two million zombies also represent more than two million primary crystals. Therefore, Shen Yan's side can definitely be said to be a shotgun in terms of storage space, and there has been a big change.

Not to mention others for the time being, the ten members of the Wolves team alone, now each person's space bracelet has reached five hundred cubic meters, and each person is still two configurations, which is completely for the preparation of convenient collection of materials during the battle. And for the two thousand elite wolf warriors, Shen Yan is not ambiguous at all, and the configuration of each person is all 100 cubic meters of space. Therefore, the five thousand mutant beasts are large and small, and the average volume is only three or four thousand cubic meters, and in the face of Shen Yan and the five hundred elite wolf warriors under his command, can they still fit it?

More than 5,000 mutant beasts were killed and injured under Shen Yan's joint killing, and a hundred elite wolf warriors were only slightly injured. The other four hundred elite wolf warriors only came down to collect a corpse, and there was nothing at all. The speed of retreat was extremely fast, and through the connection of the empty bridge, Shen Yan and they quickly moved to the city wall of the base, and at this time, the fire on Guan Feng's side was already raging.

"Again...... This trick, alas, the earth ...... The creatures on it are really ...... Low-grade, virus-...... The enhancement of the face ...... The flames are still so afraid! Ling Yan Thirteen, who was three thousand meters away to the east, looked at the raging fire, and felt a little helpless in his heart, although the fire together could not stop the group of mutant beasts from continuing to attack, but the chaos caused was even stronger than what Guan Feng had created with grenades before.

The street leading to the east gate was completely covered in fuel, and when the fire was not ignited, the mutants kept passing through it, and each of the morphing beasts that passed through was contaminated with a lot of fuel. And as the fire was ignited, one by one the mutant beasts were instantly covered by flames, and those mutant beasts with fire on their bodies let out terrible screams one after another, crashing around frantically, and in the blink of an eye, those mutant beasts that were contaminated with fuel but not ignited were ignited. This scene is like a torch relay, one implicating the other, when many chameleon beasts with fire on their bodies gather together, and even ignite those mutant beasts that are not contaminated with fuel, after all, they have no less hair on their bodies.

The effect of the fire only played a certain disturbing role, and the number of mutant beasts that could be affected was only tens of thousands. Therefore, if you really want to exterminate the mutant beast, you still have to rely on normal killing methods.

"Crunch!" The east gate of the base slowly rose, but the gate stopped after only three meters high.

The mutant beasts finally found the way to the inside of the base, and they swarmed for a while, but there were too many of them, and under the hugs of the front and back, the mutant beasts in front did not run into it by themselves at all, but were pushed into it by the mutant beasts in the rear.

Shen Yan had already arrived in Urn City, and when the gate opened, he stood in front of another gate leading to the interior of the base in Urn City, along with ten members of the Wolf Team including Guan Feng. At the same time, there were nearly a thousand elite wolf warriors lying on the three walls of the urn city, and outside the urn city, there was a circular defense line formed by thousands of war wolves.

"Damn, do this kind of crazy thing with you little pervert and pervert, don't you think the space here is too narrow?" His eyes were fixed on Guan Feng, who opened the door, and he couldn't help but turn his head and glance at Shen Yan and scolded: "How do I feel, I am like the eighth king in the urn now, waiting for the mutant beast to come and eat me." ”

"Haha, Captain, if you're afraid, just leave! Chirp crookedly doesn't look like you at all. Shen Yan teased in response, but his eyes were fixed on the slowly opening door.

Indeed, as Guan Feng said, the space in the urn city was too narrow, and after the mutant beasts outside swarmed in, the momentum they formed under the wild rush was by no means something that ordinary people could resist, even if it was the first time for Shen Yan himself to face such a scene. This is not just killing mutant beasts in the southeast, after all, there is still room for maneuver over there, and there are still buildings to drill if it is really not possible. And this urn city has been closed at this moment, and they can only resist in the face of the charge of mutant beasts.

However, the strength of the seventh-level enhancement made Shen Yan feel a little worried in the face of the impact of the mutant beast, but more than that, he had strong confidence. Even if it was Guan Feng, it was already a sixth-level strengthened existence, and the other eight members of the Wolves team were now all fifth-level existences. The number of mutant beasts is indeed large, and they who have gone crazy are indeed more fierce in the face of this small space, but after all, their level is only two or three levels, and such an opponent is completely a piece of cake for them.

Fighting is the best way to hone strength, strong pressure is the best means to break through strength, in order to improve his strength, Shen Yan must do this, he can't wait for Mira to upgrade and come to feed. In fact, this is not just his own idea, although Guan Feng is chirping, but this is just a way for him to relieve pressure, the glory of the past has passed, and now he is facing more danger than when he came out, he just has a better start than most people.

"Boom! Rumble! Boom ......"

The mutant beast finally came out from under the gate, and Shen Yan could clearly see that the mutant beast in front of them was not running in, but rolling into the gate after being pushed by the companions behind.

"Come on, let me see how strong you really are?" Shen Yan shouted in his heart, and a pair of dragon teeth held in his hands were tightened by him.
