After packing up the spoils that the ghost wolf exploded, I walked through the aisle and entered a hall. The hall was about 200 square meters and was illuminated by the fluorescent lights on the ceiling. It was completely different from the narrow aisle before. Only those broken instruments and mottled blood stains mean that it was not peaceful here.

There is an alloy door on the walls around it, and the silver-white alloy door is tied up, and low sounds come from outside the alloy door directly in front.

"There are four waves of monsters here. The first two waves are zombies, the third wave is a virus carrier, and then a few mechas. After this, it will be the final boss." Xia Tian said. After all, Xia Tian had personally visited the war zone laboratory several times, and he knew much more clearly than Ye Luo.

Zombies move slowly and carry toxins in the attack, which is easier to deal with for long-range professions. In the war zone laboratory with ordinary difficulty, there are about ten zombies in the first wave and fifteen in the second wave.

The seemingly very strong alloy door was knocked open by a powerful force, and a ferocious zombie rushed in with a roar. Of course, two bullets were greeted.

Polluted tester, level 20, ordinary monster.

These zombies were wearing broken work clothes, with only the whites left in their eyes. The blood volume of one zombie was about 2,200. This hall was big enough that Ye Luoxia and the others could easily deal with these zombies.

The second wave of zombies broke into the door three minutes later. If the first wave of zombies were not cleared out in time, the difficulty of the two waves of zombies would increase sharply. The average team can easily solve the first wave of zombies. There are only two gunmen in this team, Ye Luo and Xia Tian. It is hard to say whether they can clear ten zombies in three minutes.

Zombies have a high attack and also have toxin attacks. With Ye Luo's life and defense, they will get residual health if they are scratched to one claw. First of all, you have to ensure your safety, which will inevitably reduce the output. You can resist several attacks in summer, but after all, you are not a warrior and cannot carry the zombie attack to output.

One left and one right in this hall, they were dealing with the zombies. Each time they attacked the same monster. As the number of zombies decreased, the pressure became smaller and smaller. They killed eight zombies in three minutes.

"I've upgraded." Ye Luo laughed. When he was in the War Zone 131, his experience was nearly level 12. He killed seven level 18 ghost wolves and eight level 20 zombies, and directly upgraded to level 12, and his status was full!

The metal door on the left was also knocked open, and more zombies rushed in, making the hall crowded suddenly. Ye Luo put away the sniper rifle and replaced the Sand Eagle. Although the single damage of the sniper rifle is much higher than that of the Sand Eagle, the firing rate is far less than that of the pistol. Anyway, Ye Luo has not learned the counterattack skill that requires large guns to release, so it is more appropriate to use a pistol now.

He sideways and avoids the zombie's pounce, stepped on the zombie's buttocks, and stuffed all the remaining bullets in the magazine into the back of the zombie's head, and more than one hundred damage appeared one by one.

Ye Luo's eyes lit up and he shouted, "The back of his head is the key!"

"receive!"

Hitting the back of the head can cause about twice the damage. It is an ordinary key. After knowing the key, killing monsters will be much faster. Ye Luo's soul is dealing with several zombies' claws. Bullets can always accurately land on the back of the zombies' head. The zombies roared repeatedly, but they had no choice but to watch their health decrease little by little.

"There is one minute that the big zombies are about to come out, and there are still six zombies left to try to kill them in one breath!" Xia Tian said.

The dirty blood flew everywhere, and the leaves inevitably got some blood on their bodies. These traces will be automatically refreshed by the system in half an hour.

He killed 17 zombies in three minutes, which was more than twice as good as the first time. Even two level 20 gunmen were difficult to achieve this result. In addition to the two of them's powerful skills, key attacks are also an important factor in laying this speed.

17 zombies at level 20 have increased Ye Luo's experience by 5%. It has only taken more than ten minutes to enter the dungeon. After all, it is a level 20 dungeon, which is higher than Ye Luo's level, and the experience bonus is very high.

With a blast, the alloy door was directly hit and bounced to the wall at the other end. A monster behind the alloy door directly squeezed the door and penetrated into the hall. The monster was more than five meters tall, full of strong muscles, and his head was covered with blood. I don’t know if it was his own or someone else’s. The monster was covered with disgusting green liquid flowing all over the monster. His white eyes turned and locked directly on Xia Tian’s body.

"Damn it, it's me again."

Virus carrier, level 25, elite monster.

"The big zombie has about 12,000 yuan in health, and its defense is average. It will be damaged by toxins within two meters near the body, 20 yuan per second, the melee nemesis." Xia Tian said.

Both are elite monsters at level 25, the big zombies do not have many long-range attack methods, and the threat to Ye Luo and the others is far less than that of the elite expelling mechas. As long as you avoid the toxin spit, the long-range profession can easily grind them before the 30% of the blood volume of the big zombies.

When the zombie is 30% of its health, it will enter a violent state, its defense is reduced, its attack power and movement speed will increase. The first attack will be accompanied by a stun effect, and the toxin damage within two meters will become 30 per second. If Ye Luo is caught up and slapped, it will definitely be instantly.

The big zombies in the violent state have almost no defense. Ye Luo kept each shot at around 120 to 140. The key to the zombies is the back of their heads. When they reach the big zombies, they will not work, but the blood volume of more than 3,000 was quickly worn down.

"Hide in the corner, this guy is about to explode." Xia Tian shouted.

The blood volume of the big zombie is less than 3%, and a lot of green liquid suddenly gushes out. Xia Tian said that the big zombie is immune to all damage below 1,000 points and can only dodge honestly.

When the first time the war zone laboratory was opened, many teams suffered a lot here. After detecting the abnormality of the big zombies, they accelerated the output. They found that they did not cause any damage to the big zombies at all. After the big zombies self-destructed, they would not have different damage to the whole hall. Only by starting the shield war and heavy battle with defensive skills in time can they survive.

Even if it was just ordinary difficulty, many level 20 teams returned in terror. Until later, more and more people passed the war zone laboratory, and the complete strategy was also circulated. When the big zombie self-destructed, as long as they hid in four corners, a protective cover would rise, and the self-destruct preparation time was only 5 seconds. Professions with slow movement speed could only seek more blessings.

Ye Luo had watched the video and knew that there was this one now. He quickly leaned against a corner tightly. The big zombie roared, and his body swelled up like a balloon and exploded with a bang!

The misty green poisonous fog fills the entire hall. All players in the poisonous fog will suffer 2,000 points of ignoring defense damage at one time. Ye Luo hid in the corner, and a light curtain shot out from the wall, covering this small place less than one square meter, isolating all poisonous fog, and the light curtain disappears again until the poisonous fog dissipates.

System: Kill elite monster virus carriers and obtain experience value of 2680.
