Regarding the question raised by Gao Zhuling, Zhang Xiangyang finally gave the conclusion: "The galaxy system of the triad star is extremely unstable, and the living environment is also extremely harsh, even if there are terrestrial planets, it may not be suitable for human migration, and he believes that the instability of the three-body galaxy is likely to eventually lead to its evolution from a three-star system to a two-star system, and this evolution process will bring extremely strong destructive power, so that even if human civilization can gain a firm foothold and survive on the terrestrial planet of Proxima Centauri, it is not a long-term solution after all." , which is why Sirius, which is twice as far away as it, is considered. ”

At the end of the report, Zhang Xiangyang also gave his own suggestions on how human beings can fly to Sirius, and listened to him say: "If a human spacecraft takes off from the earth, it must always consider the problem of breaking free from the earth's gravity, and this process will also consume a lot of energy, if we can establish a space base on the moon, launch a spacecraft from the surface of the moon to explore outer space, and improve the power system of the existing spacecraft, and introduce a controllable nuclear fusion thruster that has become mature and stable. Then the speed of the spacecraft may be increased to 30,000 kilometers per second, so that the time we can fly to Sirius can be reduced from 86,000 years to 86 years, that is, the speed is a full 1,000 times faster! ”

"Wow! ————”

There was an exclamation from the audience, and everyone unanimously expressed their shock at this conclusion.

"And that's not the most exciting, because in addition to controlled fusion propulsion, we can also consider using antimatter propulsion and building an antimatter spacecraft, so that theoretically, the spacecraft can travel close to the speed of light, and we could really fly to Sirius in 10 years......"

"Wow! ————”

There was another exclamation in the audience, and Zhang Xiangyang had not finished speaking, he continued: "However, because the gamma rays generated by antimatter power are extremely harmful to the human body, it is necessary to redesign the internal structure of the antimatter spacecraft, install a strong ray protection device, and under high-speed flight, the spacecraft itself also needs to have a strong protection system, which can resist the friction and collision of space dust or particles and larger volume obstacles. When we are about to reach our destination, we have to think about braking and slowing down......"

"Boom! ......" burst into laughter.

"Alright, that's all for my report today, thank you!"

"Smack! Syllable! Syllable! Syllable! ”

With the warm applause from the audience, Zhang Xiangyang also bowed to everyone.

Although Bai Lidu listened to the whole report with relish, and even a little unsatisfied, he did not forget the purpose of his and Ruolan's trip, but this report meeting is about to end, and the accident that happened to Gao Zhuling has never appeared, could it be that the accident was canceled by the system? It shouldn't be......

Just as Bai Lidu kept muttering in his heart, a task prompt finally appeared:

- Task Tips: Due to some of the ideas put forward by Dr. Zhang Xiangyang, it will have a great impact on the future direction of the current dungeon world, a kidnapping operation against Dr. Zhang Xiangyang is unfolding, you have activated the random quest "Protect Zhang Xiangyang" of the space-time dungeon, please protect Zhang Xiangyang from being kidnapped, and pay attention to protect Gao Hongbin and Gao Zhuling at the same time in the process, task reward: unknown.

Similarly, Zhou Ruolan also received the same prompt.

……

After the end of the lecture, Bai Lidu and Zhou Ruolan accompanied Gao Hongbin and his daughter to the backstage of the multi-functional lecture hall, and met Dr. Zhang Xiangyang, who had just finished the keynote speech, in a room for VIPs to rest.

Bai Lidu guessed in his heart that in the original history, it was likely that Gao Zhuling also raised that sharp question in the report meeting, and after obtaining Zhang Xiangyang's approval, he was also invited to come to this room after the report meeting, so he was involved in a kidnapping incident against Zhang Xiangyang, and the result was that Zhang Xiangyang was kidnapped, and Gao Zhuling was killed.

Bai Lidu also quickly told Ruolan about his guess, and Zhou Ruolan also agreed.

"Haha, Dr. Zhang, your report is very exciting," Gao Hongbin said with a smile as soon as he entered the room, and stretched out his hand to shake hands with Zhang Xiangyang.

"Where, in front of you, I'm the class with an axe, hey, this classmate Gao Zhuling is ......" Zhang Xiangyang shook hands with Gao Hongbin while also noticing Gao Zhuling on the side.

"Ah, haha, Zhu Ling is my daughter, and the two next to me are my assistants, Li Dubai and Hua Ruolan!" Gao Hongbin introduced his daughter and introduced Bai Lidu and Zhou Ruolan by the way.

"Haha, no wonder, it's really a tiger father and a dogless girl!"

Bai Lidu took the initiative to step forward, stretched out his right hand and said, "Hello Dr. Zhang, your report is very exciting, I am Li Dubai......"

Bai Lidu also put on a thief's mask before this.

Zhang Xiangyang also enthusiastically stretched out his right hand, shook it with Bai Lidu's right hand, and said, "Li Dubai, what a name......"

- System Prompt: The resident effect Stealing Mask Technique has been successfully activated, and you have successfully stolen [Zhang Xiangyang]'s face, and you can temporarily use this face for the next 1 game day.

Seeing that the thief had succeeded, Bai Lidu immediately said loudly after finishing the handshake: "Dr. Gao, Dr. Zhang, and classmate Zhu Ling, let me be an offensive reminder, this room is very dangerous at the moment, a group of evil forces are planning to kidnap Dr. Zhang, and Dr. Gao's father and daughter are also likely to be implicated, so I suggest that the three of you should find a safe place to avoid for a while, and the scene can be handed over to me and Ruolan to deal with and deal with." ”

"What? Someone is going to kidnap me? How is this possible? How do you know? Zhang Xiangyang immediately expressed strong doubts about Bai Lidu's words.

"Dr. Zhang, I believe what Li Dubai said, I think it's better for the three of us to follow his advice, is there a place in your room where we can take a shelter for a while?" Gao Hongbin also expressed his opinions in a timely manner.

"Dad, there's a bathroom here, you should be able to come in and take shelter!" Gao Zhuling was apparently on his father's side, and had quickly found a bathroom in the house.

Zhang Xiangyang obviously refused to give in easily, and said to Bai Lidu: "You haven't told me yet, how did you know that there was going to be a kidnapping case against me, even if Dr. Gao believed you, but why should I believe you?" I hope you can come up with enough evidence to convince me......"

Time was pressing, Bai Lidu didn't plan to talk nonsense with him, so he directly replaced his face with Zhang Xiangyang, and even completed the replacement of his name at the same time.

"Ahh

Zhang Xiangyang, Gao Hongbin, and Gao Zhuling all let out exclamations, after all, this kind of face-to-face operation is too unbelievable for the three people who are still in modern civilization, and they can't understand it at all.

"Now, you should trust me, right?" Bai Lidu asked.

"Tuk! Sincere! Sincere! ……”

Without waiting for Zhang Xiangyang to answer, there was a knock on the door in the room.

"Dr. Zhang, don't hesitate any longer, the three of us have to hide......" Gao Hongbin said quickly on the side.

"Okay, for Dr. Gao's sake, I'll believe you." Zhang Xiangyang said that, and hid in the bathroom with Gao Hongbin and Gao Zhuling.

"Tuk! Sincere! Sincere! …… Is Dr. Zhang here? ”

There was another knock at the door, and someone asked, but it sounded like a woman.

"In! Here it ......."

Bai Lidu replied, and walked over to open the door, only to see a strange woman standing outside the door......
