According to Liu Gan's estimate, the order of the twelve zodiac signs this time is no longer the twelve zodiac signs, but has been changed to twelve hours. So, he just needs to find the order of these cells in the order of twelve hours.

Zi hour, Chou hour, Yin hour, Mao hour, Chen hour, Si hour, Wu hour, Wei hour, Shen hour, You hour, Xu hour, Hai hour.

Sure enough, on the wall of one of the cells, Liu Gan saw the dark patterns of the ancient text "Zi". It seemed that this was the first zombie that needed to be hunted.

After Liu Gan and Liu Ruyan worked together to crush the banned light curtain of the cell, the two of them killed the zombie in a familiar way, and then Chou Shi, Yin Shi...

After killing the twelve zombies in sequence, the system did not show any prompts of the last task failure, but instead flashed a green aperture in the center of the hall, indicating that Liu Gan and Liu Ruyan entered the aperture.

When Liu Gan and Liu Ruyan stood within the green aperture range, a rumble sound was heard on the ground where the green aperture was located, and then it began to slowly descend, which looked like a lift, leading to an area below the ground.

After the lifting ladder stopped, Liu Gan and the others came to a cabin underground. According to the prompts, they opened the cabin door in front and reached the last level and could communicate face to face with the level 9 wavess.

Fortunately, the chip in the brain has a playback function, otherwise, Liu Gan would not think that he would notice the dark patterns the second time or the third time. What's more, these dark patterns will change every time. Twelve zombies attack the light curtain together and will all come out in a quarter of an hour, forcing players to focus on how to eliminate these zombies, so it will not be easy to observe the dark patterns on the wall behind them.

After opening the cabin door in front of me, there was a hall larger than the first floor lobby, each with a length of more than 20 meters wide. After the two entered the hall, a zombie fell from the sky and appeared more than ten meters away from them.

The zombie held an orange-loaded pistol in his hand, and then shot Liu Gan. The energy bullets flew out of its pistol like a submachine gun, instantly evacuating about fifteen percent of Liu Gan's armor energy!

"Damn it! Can a pistol be used as a submachine gun? Is level 9 zombies so fierce?"

Of course, Liu Gan immediately rushed over and called the level 9 zombie with a abilities. After the Bone Slash and the Lengkong Slash, Liu Gan did not use the Overlord Slash as usual, but stopped.

Because, the moment Liu Gan approached it, this level 9 zombie suddenly changed. Liu Gan's attack just now fell on one of them, and it could not cause any damage to it!

"Attack that one! This is just a phantom!" Liu Gan shouted at Liu Ruyan, gave up attacking this zombie, and attacked the other zombie.

"Bang bang!"

Liu Ruyan fired the gun and cooperated with Liu Gan to shoot at another zombie, but it also failed to cause any damage to it.

The two zombies each held an orange-mounted pistol and shot at Liu Gan and Liu Ruyan respectively. This time they did not cause the kind of submachine gun-like damage they had just made, but the bullets they shot were not phantoms. They actually took some of the armor energy of Liu Gan and Liu Ruyan respectively!

"None of them are phantoms! And they are invincible! How to play this?" Liu Gan cursed, not knowing what to do for a while.

The attacks of Liu Gan and Liu Ruyan were ineffective against the two zombies, but the two zombies did not stop shooting and attacking Liu Gan and Liu Ruyan for a moment, drawing out the armor energy outside Liu Gan and Liu Ruyan's bodies bit by bit.

"Calm down! Calm down! There must be some rules that have not been cleared. These rules should be prompted in some places." Liu Gan tried hard to calm himself down, and then ran around the hall, looking around the surrounding walls, ceilings, and ground, wanting to find relevant rules prompts.

Soon Liu Gan found two clues.

There are two huge murals, one on the wall to the east and one on the wall to the west.

The mural on the east wall depicts a pair of brothers hugging each other tightly, and the two showed happy smiles on their faces; the mural on the west wall depicts the brothers separated and looked at each other with tears in their eyes and sadness.

"I understand! They must be separated to a certain distance before they can be effective!" After Liu Gan figured it out, he immediately explained to Liu Ruyan. The two of them attracted the hatred of the two zombies and ran towards the two diagonals of the hall.

One of the two zombies chased Liu Ruyan, and the other followed Liu Gan to another diagonal. After feeling that the distance between them should be far enough, Liu Gan turned around and launched a supernatural combo to the zombie chasing him. At the same time, he also released an alien zombie to assist Liu Ruyan. If she could not make a meat shield for Liu Ruyan, her pressure would be greater.

Sure enough, this time the zombie is no longer invincible. Liu Gan's supernatural attack was attacked and took time to 20% of the zombie's energy, but the actual energy drop of this zombie was about 33%. Soon Liu Gan understood... These two zombies are in the common energy trough, and the additional damage of about 13% was caused by Liu Ruyan just now.

After being attacked, the zombie became furious. After retreating quickly to the distance, they launched the submachine gun-like continuous shooting at Liu Gan and Liu Ruyan again, causing about 15% damage to Liu Gan's armor energy again. Liu Ruyan's armor energy was evacuated by about 20%. The reason for this difference should be related to the two orange armor chips.

Although Liu Gan and Liu Ruyan are still only at level 8, their strength is even higher than that of normal level 9 players. After finding the correct attack method, they took a few minutes to easily knock down the level 9 wave ss zombie.

The last blow Liu Gan was handed over to Liu Ruyan.

The reason why Liu Ruyan upgraded first... is that this level 9 wave ss happens to be a gun. If Liu Ruyan kills it, the possibility of bursting out a gun-like superpower chip will be very high. Liu Gan is no longer short of chips now. It would be great if Liu Ruyan could explode the submachine gun-style superpowers used by the level 9 wave ss zombie just now.

After the level 9 wave ss zombie fell to the ground, an orange treasure chest was burst out, an energy level 3 superpower chip, ten rare-level special alloys, twenty level 4 soul beads, and a storage value card of 50,000 energy coins.

The energy level 3 superpower chip is an attack-type superpower chip that can be used by a pistol called "Quick Fire"! According to the instructions, there is no doubt that it is the submachine gun-style rapid-fire superpower used by level 9 waves just now. (To be continued.)
