The tide of corpses will arrive at the Southern Qi base in ten minutes. Although we know that the zombies in the northern kingdom are very strange and their movement speed is very slow, no one like Lin Feng has really seen the appearance and movement speed of these zombies. Seeing can make the most accurate battle plan.

In order to prevent the base from being directly attacked, Lin Feng still used heavy laser cannons and super heavy laser cannons in the front row of the base as before, and a team of dozens of people with concentrated nuclear magnetic rocket launchers was used to harvest.

However, the energy-gathering nuclear magnetic bazooka at the Nanqi base is different from the ones used at the Beishan base. There is an extra energy slot on the barrel of these bazookas, which seems to be placed with crystals, so this energy-gathering nuclear magnetic bazooka is an improved product. It can be launched alone , You can also use crystals as energy to launch more powerful shells.

Lin Feng is now instructing Manager Qian to take the laser cannons to the outside of the base to arrange them, and to take some people to line up the laser tanks in the gaps between the super-heavy laser cannons, so that the front of the base is completely covered by weapons.

In the arsenal, apart from large weapons, the only weapons that can be held by people are laser rifles and laser super-heavy snipers. The number is still amazing. One can imagine how many people were guarding the Nanqi base in the past.

And now the Southern Qi base has turned into a dead city, what happened?

Manager Qian used the post-apocalyptic watch to transmit the dynamics of the zombie group outside the base. From the screen, the speed of these zombies is indeed very slow. It looks like the slow-moving zombies in Plants vs. Zombies, and these zombies look the same as before. It's different, exactly where it's different Lin Feng didn't remember.

In the northwest corner of the arsenal of the Nanqi base, Lin Feng discovered a hidden door. The iron door with the same color as the wall was very thick. It was only when Lin Feng pushed it open that he realized the secret of the door. It turned out that the door was wrapped in iron. All the walls and the canopy floor of the room behind the secret door are made of lead, and the function of lead is to isolate energy.

That's right, the room behind the secret door is full of crystals. There are all kinds of crystals in the zombie's brain. The lowest level of crystals is light yellow crystals, the highest is red crystals, and there is another kind that Lin Feng has never seen before. Blue crystals, there are hundreds of thousands of these crystals. Lin Feng knew that the red crystals were the brain crystals of level-6 zombies, so the blue crystals should only be found in higher-level zombies. He never expected that the Nanqi Base could collect them. So much vigilance, but it doesn't look like the crystals are being used.

There is also a crystal library hidden in the weapon arsenal, and it is sealed with a room of lead. It stands to reason that this is redundant, because although practitioners can absorb the energy of crystals, they cannot feel the existence of crystals outside, and in It is very dangerous to absorb energy near weapons. If you are not careful, the energy in the crystal will activate nearby weapons, and even powerful practitioners will die here.

Ordinary practitioners of course cannot feel the energy of the crystals from the outside world, but Lin Feng is different now. After he learned the magic wolf technique, his passive skills have always allowed Lin Feng to feel the energy fluctuations and energy levels around him, but in Outside the room made of lead, Lin Feng could only feel the energy of a dozen or so sixth-level zombies.

A room made of lead can't stop the energy leakage in the crystal pool. What if the room made of lead is destroyed? Will there be super energy equivalent to the explosion of an antimatter weapon?

"Could it be that the reason why this crystal library is so tight is to prevent someone from finding it, and this person should be referring to the zombies?"

Lin Feng suddenly thought of the secret of the crystal vault. If it is to prevent practitioners from stealing the crystals, it is really unnecessary to do this. The only reason that can explain the crystal vault and the weapon vault is the zombies.

Perhaps the energy of the crystals in the crystal library is too huge, but this energy can be sensed by zombies. Low-level zombies will look for high-level zombies, and high-level zombies will look for higher-level zombies. When zombies reach a certain level, they will mutate Mutated high-level zombies are produced, and the mutated zombies will attract low-level zombies to their side and devour them to provide energy for themselves.

If this cycle is established, it makes sense that the Nanqi base has so many super-large weapons and ultimate weapons, but Lin Feng can't figure out why the Nanqi base has such a large crystal library. If these crystals are hunted by the Nanqi base In the end, Lin Feng definitely didn't believe it.

Not to mention that there are as many as 100,000 low-level zombie crystals in the crystal library, and there are thousands of red crystals in the crystal library. Those are all produced by level-6 mutant zombies, and level-6 mutant zombies are What a terrifying existence, Lin Feng, a peak cultivator of level nine, couldn't easily deal with it, not to mention how terrifying the number of red crystals here is.

In addition, there are blue crystals in the crystals, which are crystals that Lin Feng has never seen. From the perspective of energy fluctuations, the energy of the blue crystals is many times higher than that of the red crystals, which should be level 7 zombies or above A senior zombie, Lin Feng felt scared just thinking about it.

Besides these crystals, Lin Feng found something that made him very excited in a locked box by the wall.

"Black beads"!

Seeing the things in the box, Lin Feng felt indescribably happy. The production of this kind of black beads is very rare, but the number of black beads in this box is astonishing, there are hundreds of them, but these black beads have no energy It is also impossible to tell from the appearance what level of zombies the black beads are produced from. At present, they can only be put into the doomsday watch first, and then taken to the supermarket for testing after defeating the zombies.

Lin Feng was the only person in the crystal storehouse. Elder Sima and other subordinates stayed outside to keep watch. The inventory of the crystal storehouse was astonishing. Lin Feng did not plan to announce this, because if this place was made public, some people with ulterior motives would find a way Stealing, if the door is opened, the energy of the crystal will leak out, and more zombies will be attracted at that time, and the blue crystal will definitely attract more advanced zombies.

The weapon arsenal and the crystal arsenal have been inspected. Now Lin Feng has to arrange a specific battle plan. Although there are a large number of zombies outside, their movement speed is very slow. With this, Lin Feng is sure that he can repel this wave of corpses. He believes that what the Nanqi base can do, he can do it too.

When leaving the crystal library, a wall next to the crystal library caught Lin Feng's attention, because there were a lot of ice crystals on that wall, many, many very regular ice crystals. (To be continued.) For mobile phone users, please visit m.wenxue6.com for a better reading experience.
