Bai Xiaofei's heart was a little calm, and he was about to ask Long He, what weakness Xu Fu had, when suddenly Ling Lan's telepathy came to his mind: "Bai Xiaofei, Nima said that there is a very urgent matter to find you, let you rush to her as soon as possible - this matter is related to the earth and the other world!" ”

Bai Xiaofei immediately said: "Give me Nima's coordinates, and I'll rush there immediately." He looked at Long Ji, and Long He nodded: "Xia Gu and I will go with you." Aunt Xia snorted: "Who is with you, so shameless, Long And, our business is not over yet!" Having said that, Xia Gu still rose into the air, and together with Long Ji and Bai Xiaofei, flew towards where Nima was.

Nima is not in H City, nor in the capital, but in a desert in the northwest.

Nima set up a temporary laboratory in the deepest part of the desert, and a large group of corpse brothers and soldiers were busy digging a deep pit with a diameter of several kilometers, seeing Bai Xiaofei and Long Ji and Xia Gu behind him, Nima nodded and said: "Great, with the three of you here, my experiment will be more certain." ”

Bai Xiaofei asked hurriedly, "What experiment?" What does it have to do with the survival of the other world and the earth? Nima, the invasion of another world is coming, why don't you hurry up and study the spaceship of the space immigrants, what the hell are you doing in this desert with only sand? Bai Xiaofei was a little speechless, during this period of time, he was repeatedly frustrated, in a bad mood, frustrated and disappointed, almost crushing his always tenacious nerves.

Nima was not angry, and said to Bai Xiaofei: "Bai Xiaofei, this experiment is very important, if my analysis is correct, we have added a powerful super weapon against the invasion of another world." ”

Bai Xiaofei was stunned for a moment, and continued to be overjoyed - if Nima used "super weapon" to describe a certain weapon, then the power of this weapon is definitely not under Shenzhou No. 1! --"What kind of weapon?" Say it! ”

Nima looked directly at Bai Xiaofei: "Do you know antimatter?" ”

Bai Xiaofei nodded: "I know, this is a conjecture of physicists, they believe that after the Big Bang, positive matter and antimatter were produced, and what we can usually see and detect is positive matter, but there should be the same amount of antimatter, hidden in the universe." Mankind has been exploring the search for antimatter, believing that it can unravel the mystery of the birth of the universe. ”

Nima pushed his glasses: "Very correct answer, then do you know what happens if positive matter meets antimatter?" ”

Bai Xiaofei frowned: "Well, human beings have not found antimatter so far, but scientists believe that once the positive and antimatter come into contact, they will annihilate each other, and when they are annihilated, they will burst out with huge energy." The power of this explosion is several times that of nuclear fusion, and some people have even calculated that as long as 7 grams of positive and antimatter are annihilated, the entire earth can be destroyed. He quickly came to his senses: "God, Nima, you can't have obtained antimatter, right?" Wait, I've never heard of you doing research on this, huh? Even to scientists across the planet, antimatter is just speculation. ”

Nima nodded: "Scientists have not been able to determine what kind of existence antimatter is, but the emergence of another world has given me new inspiration. Bai Xiaofei, you have told us before that the other world is the mirror world of the earth, and everything on the earth has a corresponding existence in the other world, such as land, sea, race, and even individual life. It's just that because of the division of the sun, the other world has brought drastic changes to the environment, and the originally beautiful world has become hell. I can't help but wonder if the other world, as far as the earth is concerned, is antimatter? Isn't it the opposite that the other world and the earth are mirror images of each other? ”

Bai Xiaofei was dumbfounded, but he quickly shook his head violently: "Impossible!" No way! If the other world is the antimatter of the earth, then when the summoned beast came to the earth in the past, it would cause the annihilation of the positive and antimatter, causing a big bang! ”

Nima said: "That's because there is no real meeting between positive and antimatter - only the meeting of two specific matter, corresponding to the other world and the earth, will cause annihilation. ”

Bai Xiaofei suddenly remembered something, and he pointed at Nima: "You asked me to bring a stone from the lonely peak of another world--"

Nima nodded: "You guessed it, that stone is exactly what I used for experiments." She took Bai Xiaofei, Long Ji, and Xia Gu to the bottom of the huge pit, and in the center of the bottom, there were two stones quietly, and the appearance of the stones was exactly the same.

There is a proverb on the earth - no two grains of sand are exactly the same, but the stone placed in front of Bai Xiaofei now is exactly the same, and even Bai Xiaofei can't debate any difference when he observes it with his godhead.

Nima said: "One of these stones was taken from the Lonely Peak in the Other World by Bai Xiaofei according to my request, and the other stone was taken from Mount Everest by asking the Immortal Master and the Ginseng Doll. I thought that Lone Peak was a mirror image of Mount Everest, that is, antimatter, so I carefully measured and took exactly the same stone at the corresponding location. These two stones will be subjected to positive and antimatter annihilation tests. ”

Bai Xiaofei looked at the two stones, that was the most ordinary stone, one of which he had collected by himself, he could be 100% sure that the stone was a stubborn stone, and it had no power at all.

Bai Xiaofei laughed dryly: "Nima, I can understand you, I am eager to research a new weapon to use against Xu Fu, but this positive and anti-matter statement is really funny - these are just two stones." ”

Nima interrupted Bai Xiaofei's words: "Even if it's a joke, then you just let me try it, if it succeeds, then it's naturally better, even if it fails, we have nothing to lose, as you said, it's just two stones." ”

Nima's words were very reasonable, Bai Xiaofei couldn't refute them at all, he sighed: "Then what do you need us to do?" ”

Nima said: "It's very simple, please be on your side, once the positive and antimatter come into contact and annihilate, if the energy of the outbreak is too large, you can take action in time to suppress the energy and prevent it from scattering." ”

Bai Xiaofei looked at the huge crater, and then glanced at the boundless desert, where countless nuclear weapons have been tested, including hydrogen bombs, it is the safest test site, could it be that when these two small stones collide, the power of the explosion can still exceed the desert? Nima is so careful!

Bai Xiaofei nodded: "No problem." ”

Nima invited a few more people at this time, but it was the Immortal Master, Yu Xiaojia and Xiao Pang, the Immortal Master, like Bai Xiaofei, Long Ji, and Xia Gu, was also here to guard, but Xiao Pang wanted to take the samples for the annihilation test from the two stones by himself.
