Yu Tang looked up at the sky.

Last night's beautiful starry sky was obscured by the firelight. The missiles of the Eagle Falcon Country and the interception force of the Shenzhou Continent constantly collided in the night sky. The city was dark because of the power outage, and the sounds of panic could be heard in the distance.

Soon, however, several iconic buildings in the city were lit up again. Immediately afterward, the large and small buildings of the Holy Capital City began to glow. The standby power station began to work.

Yu Tang gently put Xia Yanqing down, took her hand, and sent her back to the dormitory.

After the two said goodbye, Yu Tang went straight to the laboratory and found Wang Qu.

"Wang Qu, can you tell me about what happened recently?" Yu Tang asked Wang Qu.

"Lately? Haven't you heard of it? Wang Qu was very surprised.

"When I was fleeing, I ran into the special combat team of the Eagle Falcon Country, and after killing them, I was isolated from the outside world......" Yu Tang knew that time was running out now, so he made a long story short and explained to Wang Qu.

"I see." Wang Qu nodded, and told Yu Tang what had happened in the past few days.

recalled that half a month ago, they were still working hard for the college entrance examination, and the two of them were full of emotion. This kind of thing that only happens in movies, they are experiencing it now, like a dream.

"So, the Eagle Falcon Kingdom is actually just trying to find an excuse, and my appearance just gives them a reason to go to war, right?" Yu Tang asked.

"Yes, at least from the current situation." Wang Qu replied.

"Then all I can do is try my best to cooperate with you in your research." Yu Tang said.

Wang Qu nodded, "Thanks to you, we solved the problem yesterday that has not been broken through in the past few years. I think at this pace, it won't be long before we can create a second key to time. Although Wang Qu has only been in contact with this project for less than a week, he has quickly caught up with the progress of scientific research by relying on his super talent and under the guidance of Yang Xiaosheng, he has been studying the information left by the ruins and the research reports in recent years.

And Xia Yanqing is because she read some of the information left by her father. Therefore, before she came, she already had some information about the key to the time, so after she came, the adaptation period was shorter than Wang Qu's, but in two days, she was able to take on some research tasks on her own. By this time, she had become one of the heads of materials research.

The speed of inheritance of human science is vividly reflected in Wang Qu and Xia Yanqing.

Yu Tang patted Wang Qu on the shoulder, "Let's continue the experiment." ”

In a vase in the laboratory, a bugging glows red.

At this moment, in a missile silo on the outskirts of the Eagle Falcon Country, a shocking conspiracy is being planned.

"The newly developed nuclear bomb with a yield of 50 million yields cannot be used by you alone, Prime Minister, and it needs to be unanimously approved by the House of Elders." The head of the silo said to the president of the Eagle Country.

"We decided to cut first. You know, it's just a process. We don't have that much time to spend on the Divine Continent, and with the help of the Seeds of Chaos, their current technology is developing at a speed you can't imagine. Maybe at the very moment you hesitate, they have already made some superweapons. Behind the president of the Eagle Falcon Country, there were five old men, and at this moment, they all raised their right hands to express their support for the president's resolution.

There are a total of six elders in the Elders' House of the Eagle Nation, and only one has not yet been persuaded by the president. But at this moment, the five elders spoke together, and together with the president, they tore apart the thousand-year-old system of the Eagle Falcon Country with their own hands.

Nuclear bombs of the 50 million yield level, aim, the holy capital!

Yu Tang was cooperating with Wang Qu and Yang Xiaosheng to do experiments, and suddenly, he felt his heart tighten. Almost at the same time, the warning of the key to time came.

"A large weapon has been detected that could threaten your life. In addition, please time travel immediately after charging, and the system calculates that based on the current causal growth trend, your causal value will exceed the causal red line within 10 minutes after the recharge. ”

"What if...... Shall I give up charging and stay here forever? I have people I want to protect. I am sure that with your help, I will remove any threat that this world poses to her. Yu Tang asked suddenly.

He wanted to protect Xia Yanqing.

"According to the system's simulation, the worldline will only collapse faster because of you, and eventually everyone will be wiped out by 'it'. But if you leave, there will be people who will survive this disaster, and among them, there will probably be your loved ones. The electronic voice said without emotion.

"Wait...... My lover? You're not talking about Xia Yanqing, right? When Yu Tang said this, his old face suddenly turned red.

However, his question was directly rejected by the key to transtemporaneous reasons, citing causal reasons......

At this time, the situation is a bit like a fortune teller in the rivers and lakes telling fortunes, and when he just talked about the key point, he suddenly stopped talking about it and threw out a reason that the heavenly opportunity should not be revealed. Usually at this time, stuff the fortune teller with some silver taels, and he will prevaricate you with some vague words, and then threaten with his fists, and he will tell you the truth.

But Yu Tang is facing a "fortune teller" who can't be seen or touched, or the kind without any emotions. Not to mention threatening people with your fists, you can't even stuff money into someone's house......

"Okay, I got it." After a long psychological struggle, Yu Tang opened his eyes.

"Yu Tang, what's wrong with you? How do you suddenly close your eyes for so long? If you're tired, you can go back and rest. Wang Qu said to Yu Tang with a concerned face.

"It's okay, are you tired?" Yu Tang responded.

"Of course I'm not tired, a great predecessor said that knowledge is the best spiritual food, and I'm very energetic now!" Wang Qu clenched his fists and looked at the incandescent lamp in the laboratory.

"That'...... Let's move on. Yu Tang finally understood why when he used to read magazines, he saw that those historical "geniuses" could work crazy with only 5 hours of sleep a day.

They are able to persevere because they love what they do.

Not long after, Xia Yanqing also appeared in the laboratory and began to study the day's data.

Yang Xiaosheng poured himself a cup of instant coffee, looked at the two young people who were thinking hard, and said with emotion, "Hey, old man, the future of the motherland still depends on you young people." ”

"Professor Yang, thank you for your tireless teachings to me, the hardships of our generation are a drop in the ocean compared to you back then, so we have to work harder." Wang Qu looked up and didn't respond.

"Hmm." Xia Yanqing also sent a voice of approval.

Yu Tang sat quietly on the experimental chair, hearing the conversation between the three masters and apprentices, he sighed, after all, he still couldn't bear to destroy this peaceful atmosphere, and told them his decision now.

Wait, he said to himself.
