When Li Mu returned to his home on Earth, he saw many missed calls on his mobile phone, all of which were called by the big guys. He replied to a call. The big guys told Li Mu that the ruby ​​had been prepared and saw when Li Mu would launch the Vidobao Aurora Cannon and explode the alien who wanted to invade the earth.

"Of course, the faster the better. I'll rush over now." Li Mu said.

"We left a special plane at the airport in H City and went directly to pick you up." The other side said quickly.

"No need, I can drive to the airport by myself, it's more convenient." Li Mu hung up the phone and drove to the airport.

As soon as I drove to the city, I saw a girl waving to him on the side of the road. When I looked closely, it was Qin Yumeng. Li Mu leaned over.

"Yu Meng, haven't you gone to school? Why are you back at this time?" Li Mu looked at Qin Yumeng strangely. Qin Yumeng should be living in a university in another place at this time, so why is he in H City?

"Uncle, why don't you have any common sense? It's May Day holiday now. I've been back for a few days and I can't find anyone to find you. I'm going back to school now. Now I'm going to the airport with my classmates." Qin Yumeng said with dissatisfied pouting.

"Don't you know that you are not allowed to park here?" A fat woman came over on a motorcycle. She saw that it was Li Mu's car that stopped, but she still walked over.

"I'm sorry, I'm sorry, I'll drive away immediately." Li Mu quickly said to Qin Yumeng and her two classmates: "You get in the car first, I'm going to the airport, and I'll take you there too."

"Forget it this time, I will issue a ticket next time I will do this." Sister Jiu said to Li Mu.

"Thank you, Sister Jiu." Li Mu quickly started the car and left. In fact, he still admired Sister Jiu quite a bit. If there were more people like Sister Jiu, the city order would be much better.

"Uncle, what are you going to do?" Qin Yumeng asked while sitting next to Li Mu.

"Go and save the world." Li Mu said casually.

"Puff!" The two female classmates sitting behind laughed: "Yu Meng, your friend is so old-fashioned. What era is now? You still use such old-fashioned memes."

"Uncle said he was going to save the world, maybe it was true." Qin Yumeng said seriously.

"Tsk, Yumeng, you are so old and still so naive. We are all college students. Forget about such old-fashioned humor." The two girlfriends naturally didn't believe that Li Mu was going to save any world. They just felt that Li Mu used an old-fashioned humor.

Li Mu didn't explain, but just smiled and drove Qin Yumeng and the others to the airport.

Because it was the May Day holiday, even the airport was crowded with people, Li Mu brought three people inside, preparing to send Yumeng in before leaving, but Qin Yumeng and the others got very bad news. There was something wrong with the flight they booked, and they didn't know when they would take off normally.

Li Mu went to ask the airport staff. The staff said it was under emergency repairs. He didn't know when it would be repaired, because there is no extra plane to use during the May Day holiday, so he had to wait a little longer. If you can't wait, you can refund the ticket in full.

"Well, come with me. Take my flight." Li Mu thought for a moment. He flew to the North Pole, and he should have passed by the province where Qin Yumeng and his school are located. He could take them all the way.

"Uncle, where did you fly? If you didn't go to City D, it would be useless for us to take it. Moreover, I don't have a plane ticket, so it's too late to buy it now." Qin Yumeng's classmate said.

"Since the uncle said that, there should be no problem." Qin Yumeng walked with Li Mu.

Qin Yumeng's two classmates followed Qin Yumeng half-believingly, and naturally they were half-believing and half-doubted. They had already seen it when they booked the air tickets before. During this period, they could not buy other air tickets to D City.

Li Mu made a phone call and soon someone in uniform came to pick him up, but it didn't look like the uniform of the airport staff, and it looked a bit weird.

"Mr. Li, the plane is ready and can take off at any time." The leader said to Li Mu.

"Can the plane stop in City D?" Li Mu asked.

"Yes." The man said directly.

"Okay, let's get on the plane and take off immediately." Li Mu waved his hand and took Qin Yumeng and the others to the airport.

Qin Yumeng's two classmates were stunned. What does it mean to stop in City D? Is this an airplane or a taxi?

The two classmates followed Qin Yumeng into the airport with a strange look. After boarding the plane, they found that there was no one else in the plane, and it turned out to be a special plane.

"Yu Meng, what are you doing, your friend? He even booked a special plane when he went out!" While Li Mu was away, the female classmate asked Qin Yumeng.

"Uncle, he runs a bodyguard company." Qin Yumeng said with a smile.

"Is the person who runs a bodyguard company so rich?" The two female classmates were skeptical.

The plane stopped at the airport in City D and put Qin Yumeng and the other three down. Before leaving, Qin Yumeng said to Li Mu: "Uncle, we will have summer vacation in a while. Can we go on a trip with me?"

"I don't know if there is time, so of course I can do it if I have time." Li Mu didn't dare to agree to Qin Yumeng easily. This little fairy is becoming more and more charming, and she is so eccentric. I don't know if she comes up with any strange ideas at that time.

Moreover, Li Mu didn't know if he had time by then.

"Uncle hates it the most." Qin Yumeng turned her head and walked away angrily.

Li Mu smiled helplessly. After reaching the location of the Vidobao Aurora Cannon, the big guys welcomed Li Mu over. Li Mu could easily see boxes of rubies piled up next to the Vidobao Aurora Cannon.

Even a man like Li Mu who is not very interested in gems can't help but be moved when he sees those boxes of beautiful rubies. If a woman is here, he will probably pounce on him like a dragon immediately.

"The high-quality rubies we can collect are all here. I wonder if these rubies are enough?" The big guys looked at Li Mu worriedly.

"I don't know, this Vidobao Aurora Cannon requires high-quality rubies as energy, but the rubies on the earth are not of high quality, so it is hard to say that it can exert almost the power of the Aurora Cannon at that time." Li Mu naturally couldn't guarantee that it would be useful.

"Will you wait until the alien spacecraft is closer to the earth before firing the aurora cannon?" said a big boss.

"You can't wait. The technology of aliens is not something we can understand. The closer they are to the earth, the more dangerous we are." Li Mu shook his head and said.

This aurora cannon will definitely not kill Longji. It is mainly to destroy their spacecraft and trap Longji and the others in space. If they are too close to the earth, who knows if they have any other means to cross the earth. And if the distance is too small, the fluctuations generated by the Vidobao Aurora cannon when it is activated will be easily perceived, and it will be too easy to avoid it.

All the big guys are now following Li Mu's horse's head. Since Li Mu decided to fire the aurora cannon immediately, he naturally did not dare to object. He quickly ordered the soldiers to throw all the rubies into the Vidobao aurora cannon.

Li Mu opened the control system of the Weiduobao Aurora Cannon and saw that the energy of the Weiduobao Aurora Cannon was rising continuously, but the energy intensity and purity data were not high, and even ten percent did not reach it, only seven percent and eight percent. This means that the Weiduobao Aurora Cannon's attack may not even be able to exert one-tenth of its power.

After most of the rubies were put into the Vidobao Aurora Cannon, the energy display slot was finally filled and the Aurora Cannon could be activated.

"The strength and purity are less than 10%. Can this gun explode Longji's spacecraft at such a long distance?" Li Mu asked Lai Cai.

"There should be no problem. Aurora Cannon originally exists to bomb large cosmic fortresses and planets. Although it cannot even exert one percent of its power now, there should be no problem if it kills a small spacecraft, as long as it is not discovered by them in advance." Lace replied.

"Not one percent of the power? Isn't it one tenth?" Li Mu asked in confusion.

"It's not what you calculated. The quality of these rubies is still too poor. I said one percent is already an ideal estimate. Maybe it won't even be able to achieve the power of one ten million," said Lai Cai.

"Forget it, let's try it. If it really doesn't work, I can only solve Longji by myself." Li Mu controlled the controller and soon saw the Vidobao Aurora Cannon accumulated with red crystals. Starting from the bottom layer, a strange red light shone out, and then the light rose layer by layer, and the process was quite slow.

Everyone looked at the red crystal-like pyramid nervously. This cannon has already held the hope of all earthlings. If even this cannon cannot defeat the invading aliens, it will be a disaster for all humans.

About half an hour passed, a red light finally appeared at the tip of the pyramid. The entire pyramid emitted a strange red light, and all the red light condensed towards the tip. When the fearful red light condensed like a small sun, it suddenly erupted a red aurora like a volcano erupting, instantly penetrated the atmosphere and bombarded into space at an incredible speed.

Everything that blocked the red aurora evaporated into gas instantly, even the huge meteorites that were as huge as islands were no exception.

The big guys who saw all this through the video sent by the satellite guards all showed joy on their faces. They were originally a little doubted whether this aurora cannon was really as powerful as Li Mu said. Now it seems to be even more powerful than Li Mu said. At least humans themselves have not yet created a weapon that can attack at such a long distance. (To be continued. (.))
