Regarding the cleaning of the battlefield, Lin Feng has always been selfish, he thinks that whoever kills the zombie trophy is who's own, it's just a crystal of energy, there is no need to make enemies with others because of what you can still get, there are a lot of zombies on the battlefield this time, and there are also a lot of crystals for energy, but there are no high-level zombies, these people shouldn't make anything happen because of some low-level crystals.

What Lin Feng had to do now was to find out what unknown weapons were in the arsenal, and what the huge weapon in the crystal arsenal was for.

These things don't seem to have anything to do with Lin Feng's homecoming, but if you think about it carefully, you will find that many of these weapons are not available in this world, such as 'quantum cannonballs', because there is no quantum doctrine in the end times, so Lin Feng feels that this weapon should be made by people in his own world.

As for the question of energy, it seems that only the quantum theory can fully explain the demise of energy, and only the quantum theory can maximize energy.

The huge weapon in the crystal library is to use the energy in the huge underground energy pool as the emission power and energy source, and the energy of the underground energy pool is not artificially created energy, but the energy in nature, which can gather the energy of the natural world together, except that the natural world is formed by itself.

Perhaps someone like himself wondered where the low temperatures in the northern country came from, why the snow line produced cold energy waves, and who discovered the energy pool and created this weapon on it.

Lin Feng didn't know who did it, but he was sure that this person might have the Demon Wolf Technique.

Because in the last days, there are very few divine souls that can see the energy level, and the divine souls of these people have limitations, that is, they can only see the energy level of the cultivator or the type of divine soul of the cultivator, and the divine soul that can see the energy fluctuations of the outside world has not yet been discovered.

And now Lin Feng knows, the only thing that can see the fluctuations of external energy is the active skill of the Demon Wolf Technique, but the Demon Wolf Technique is a technique only available to the beast clan in the ancient underground city, and he just happened to change the Demon Wolf bloodline gene in the exchange machine in the supermarket, and happened to learn the Demon Wolf Technique, if all this was just a coincidence, Lin Feng didn't dare to believe it.

If the Demon Wolf Technique is the only way to see through the energy of the outside world, then this weapon is likely to have been made by the orcs of the ruins of an ancient underground city.

There is a person among the orcs who knows the magic wolf technique, and he has discovered the naturally formed energy pool under the northern country, but this energy is very huge and cannot be used directly, and the cold air cannot change the temperature, so the orcs should want to use this weapon as a conversion device.

However, the cold energy of the underground energy pool is very powerful, and this weapon has just been built and frozen by energy erosion, or because this weapon is too powerful, it is frozen and surrounded by walls.

Now Lin Feng wanted to test this weapon, originally he just wanted to find clues from the weapon, but he didn't expect that looking for it was very similar to trying this weapon, he wanted to know how powerful the weapon made by the orcs was.

In order to prevent the cold air underground from appearing again, Lin Feng released the silver wolf from the doomsday table, he asked the silver wolf to stare around, and once the cold air appeared, he should immediately stop the cold air from leaking out, and then notify himself.

The silver wolf nodded to show that he understood what Lin Feng meant, and then Lin Feng came to the weapon's console, ready to activate this huge weapon.

Lin Feng had just pressed the start button, and suddenly the temperature around him became colder, but there was no cold leakage from the ground, and the cannon body of the weapon also became colder, and the ice on the cannon body had obviously thickened.

The actual energy on the weapon's display table is gathering, and there are still 10% to launch, and the time is about 1 minute, within this minute, Lin Feng feels that the temperature around him has dropped by at least ten degrees, and the thicker the ice on the cannon, the higher the energy value on the display table.

"Sure enough, this weapon is powered by the cold energy in the underground energy pool."

When the energy value on the display table reached 100%, Lin Feng changed the launch destination to the open space on the edge of the northern country, and the attack range was also adjusted to the minimum range, because it was only the experimental stage, and when he was not sure how large the killing range of this weapon was, he still had to be careful.

After adjusting all the data, Lin Feng pressed the launch button, and then a blue pillar of light emitted from the muzzle, and the surrounding temperature had dropped to more than minus 40 degrees at this time, if Lin Feng hadn't resisted with energy, he would have frozen to death.

It is also beneficial for the surrounding temperature to be lower, that is, the crystals in the crystal library next to it are all wrapped in a layer of ice crystals, these ice crystals are formed by cold energy, which can not only slow down the action of the zombies, but also seal the energy of the crystals to prevent energy leakage, so that the zombies will not be able to sense the energy fluctuations of the Nanqi base and will not attack again.

Lin Feng watched the blue beam of light launched by the weapon rush straight into the sky, and then a loud noise came from a distance, Lin Feng thought that there was an accident on the battlefield, he hurriedly put the silver wolf into the apocalyptic table, and then came to the battlefield outside the city gate as fast as possible.

The people on the battlefield were all standing in place intact, they were also frightened by the sound just now, originally when they were cleaning the battlefield, they saw a blue light shooting vertically into the sky from the Nanqi base, and then there was a huge explosion in the distance, and everyone didn't understand what was happening.

"Leader, I have already sent a disciple to check the situation, and I will know what is happening over there in a while, but I am very concerned about the beam of light emitted from the base."

Seeing that Lin Feng had also come to the battlefield, Mr. Qian thought that Lin Feng knew what was going on over there, but seeing Lin Feng's confused expression, he guessed that Lin Feng didn't know what was going on, and he didn't know if Lin Feng noticed the beam just now.

"Manager Qian, I'll tell you what's going on with that blue beam when the disciples who check the situation come back."

Lin Feng knew that Manager Qian was deliberately asking this, Lin Feng was the only one who could make a big move in the base, thinking that the beam of light must have something to do with Lin Feng, but Lin Feng was deliberately selling Guanzi, hanging on the appetite of Manager Qian.

After more than ten minutes, the two disciples sent out came back, but their expressions were a little funny, their faces were full of snot and frosted eyebrows, and the two of them seemed to have gone to Antarctica.

"Report to the leader, Mr. Qian, in the place on the border of the northern country, a big pit suddenly appeared, more than a hundred cubic meters, and this pit was filled with a whole block of ice, and the temperature around it was also very low, and we used all the energy of our bodies to barely support it."

Looking at the two disciples, it didn't look like a lie, and they also had frostbite on their bodies, combined with what they said, Lin Feng knew that it was related to the weapon in the base, but he didn't expect that weapon to be so powerful, and the speed was amazing.

"Nickname it, Ice Launcher!"

Lin Feng silently named the weapon in his heart. (To be continued.) )
