The entire underground research institute covers a large area, and there are more than ten floors in total. If a team with poor strength is defeated one by one, it can often last for a whole day, and there may not be many unlucky teams in the process?

However, with Dugu Fu's heroic monster-pulling method, in just over ten minutes, the four of them had already arrived at the seventh and eighth floors underground...

If we don’t count the overwhelming zombie army behind us, the progress of the copy will be considered to be over half!

But the heroic Rafa also brought heroic troubles. Since from this floor, due to the large number of zombies following behind him and the limited floor space, it gradually showed that the tail was too big...

Why can't you lose the big tail?

The situation is that every time the four people are down, they will rotate ninety degrees clockwise, thereby staggering the torrent of monsters following each other, and also attracting zombies on the external platform. It is like... four greedy snakes run on a screen, discussing tactics with each other, and avoiding them in an orderly manner to prevent them from colliding and dying.

However... as more and more zombies followed behind, the team grew longer and longer, and the greedy snake's body continued to expand and grow longer. Gradually, the research center's originally spacious space was a bit too short for them to run.

This is because the zombies have different speeds. Some are talented and run fast, some are average in speed, and some are lacking in arms and legs and can only move slowly behind.

If there was no one behind, they would have been unable to withstand it sooner!

Fortunately, this is not a greedy snake that will hang up once it hits, it just looks like it.

With the flexible skills of the four top experts, you can withstand the pressure of zombies. In addition, passing zombies often hate themselves and forcefully pass through each other's teams... However, during the process, it is normal to be torn, bitten, pulled, hit and affected by speed. It can be said that every time you travel, it means an adventure.

Think about it, it’s like on the bustling street, you are going to run from the crowded streets and traveling there. And everyone is your enemy, and you will give you a few strokes when you get close to you... Do you feel creepy?

But no matter how terrifying it is, you have to persevere! To achieve good results, you must take such risks!

The four people went down like this, and when their tails were too big, they could not slowly rotate and pull 90° to 180°. Then they were 270°, 360°... and responded in such a change.

After the last two levels, the situation became worse.

They pulled a surging team around the same platform, crowded with people, and could hardly tell where the exit entrance was.

At the same time, I really encountered several small bosses at the zombie captain level, or zombie mutants with special skills, mixed in the zombie bush, and jumped out from time to time to cause some trouble for them...

Among the four, Dugu Fu had the lowest strength, so he was the most passive. He was already very injured when he was chased by ordinary zombies, and with the interference of the zombie captain, he was almost rushed by the zombie team several times and was drowned in the tide of immortality.

Fortunately, he also has a life-saving prop, teleportation, healing, invincible... if you can use it, use it.

The cultivation level of the Dark Power level can offset the virus infection under the captain, and the superpowers will be selected to recover. The small injuries accumulated by the body are a little troublesome when the platform is in chaos. When the zombies enter the downward channel, the zombies cannot keep up for a while, so they can take the opportunity to recover. In addition, there are some privileges in awakening NPC, which can barely support it.

Li Shier is almost passive like him.

Why? Because Dugu Fu, Qayuliao and Xiangying have already awakened NPC. Their interface display is no different from that of players. When surrounded by groups, it is easy to distinguish the direction and find the right path through the map provided by the system interface.

And Li Shier, he did not awaken. He could not do it.

Fortunately, he has a Death mobile phone. The Death mobile phone originally prepared for players has imported the map navigation function provided by the system. Although it is not convenient to display in the direct field of view, it can still be used.

In addition, Li Shier, a natural combat madman, the more dangerous he is, the more he can explode his potential. The grandmaster-level combat power is indeed strong. If he continues to kill the generals, he is a little more relaxed and comfortable than Dugu Fu!

They both held on, not to mention the reserved Yayuyao and Xiangying...

============

arrive!

After half an hour of running, the four people stepped onto the bottom floor of the base without any particular order. They all breathed a sigh of relief in their hearts.

Half an hour! From the ground to the ground hundreds of meters deep, along the rugged corridor, you must be wary of the zombies behind you at any time. You must also explore the unknown terrain ahead. You cannot run the wrong path, hit the wall, or leak too many zombies. Later, the team grew stronger and you must also be wary of strange attacks that may come from all directions...

The tension and fatigue that went along the way were almost the same as Dugu Fu was entangled with the immortal plot characters in the second-level dangerous house.

Everyone was sweating heavily and their heartbeat was fierce. But... this was not the end, this was the beginning of the final part!

Those who travel a hundred miles apart are half a dozen, and this last part is also the most critical!

The four people who came down from the passage in four directions did not delay for almost a second. They quickly observed the map and ran at the bottom layer with zombies in the same way.

The underground research institute is a copy, and the terrain is not fixed. It is just the number of layers, the pattern of elevators going down one by one, and the general structure is the same, the microstructure, secret rooms, monster distribution, etc. are not fixed.

It was better on the road just now. The lowest floor is the largest area and the most places, and even the central elevator shaft has become a solid ground that can be stepped on... and this also includes the bottom boss that must be faced.

You must plan carefully to attract more monsters as much as possible and achieve better results!

However, the focus of passing the level is not here. But... Guo Xingxing, the boss's wife, Huan Haisha and Xia Zhiban.

Just as Dugu Fu and the other two thought to themselves, the four girls also arrived at the lowest floor through the elevator, and were slightly nervous: It was here!

For the first time, they did not follow Dugu Fu and the four men's buttocks, but chose to arrive at the same time as the four masters.

Why? Because they have to make some arrangements for the final pass...

The bottom floor of the elevator shaft is the smooth ground. Walking out of the glass-like elevator, there is no monster wandering around in the surrounding area. Even in the central area, there are dense zombies that have fallen to death, the rich doomsday virus is floating away...

This is the benefit given to the players by the system. From the elevator down to the last floor, there is such a blank area. Players can take a break and prepare for the last and most difficult battle.

So the four girls began to prepare. From each person's space bag, they took out one light, thin but very tough iron grille, just like building blocks. They quickly used this grille to surround the elevator and formed a semi-open area with a diameter of more than ten meters, up to three or four meters high, with openings on all sides.

If you have a good memory, you should remember that the system army used this kind of prop when Lingling besieged the city.

After getting the skeleton, the four girls took out the suction cups they had prepared early, started to spin around the iron grille, and shot the suction cups that were dragging the rope one by one onto the outer wall of the elevator. Soon, the ceiling composed of twenty or thirty ropes began to take shape.

Then take out the prepared canvas from the space bag, shake it open, take the pole that was also prepared early, and spread the canvas piece by piece on the ceiling.

Soon, one of them had nothing to look like, but it was actually weak and would shake if it pushed hard. If you pushed hard, you would shake it. If you pushed a few more times, the entire yurt-like thing that would fall off the roof was ready.

Although it was so rough and fragile, the girls seemed to have completed an amazing project. When the tent was set up, they all breathed a sigh of relief.
Chapter completed!
