In New York City, Qin Tian and Wesker walked on the street, their clothes from different eras attracted the sideways attention of people in this world. A man in an old suit and another person were talking about something.

"You haven't forgotten anything! Alexander. David, who was wearing a suit, said solemnly as he looked at Alexander.

"Of course, I know, cubic differential coefficients? Not this night. Alexander looked at David and said solemnly.

"Emma." David looked at Alexander for sure and said carefully.

"What time is it?" Alexander asked, confused, obviously surprised.

"It's almost five o'clock." David looked at Alexander and said carefully.

Alexander was also taken aback, thinking that it would not take long, but the result had exceeded his estimate.

"My solar plans were rejected, and so were my electromagnetic plans, which were managed to protect their interests." Alexander looked at David and said helplessly.

"The problem is that your plans are too advanced enough to change the times of everything." David said with a smile, he also admired Alexander's plan.

"He's like a dinosaur in the history department, he doesn't change, he's very rigid." David added.

While they were talking, Qin Tian and Wesker appeared in front of them, looking more unusual.

"David saw it, they looked very different." Alexander said in amazement.

"In any era, people try to wear different clothes." David shook his head and said seriously.

"I see creativity and change in them, and they are all different from the people of this world." Alexander said solemnly to David.

"Hello gentlemen, I am amazed at your service, it looks like it is the style of an era, as if we were wearing a suit and a hat." Alexander looked at Qin Tian, stretched out his hand and said with a smile.

"Alexander, you're kidding, they're not worth your acquaintance." David looked at Alexander, shook his head, and said.

"Hello Professor Alexander, I am very interested in your theory, he is able to change the future. There is also the fact that our clothes are indeed a product of the times. Qin Tian said thoughtfully, making Alexander even more interested.

"Won't you invite me to sit in your house?" Qin Tian said with a smile.

"Why not? This one is a good note, isn't it! Alexander also said with interest.

Qin Tian and Wesker came to an old villa, but Alexander's things, full of novelty, made them feel different.

"This is my house, you can do whatever you want." Alexander looked at Qin Tian and Wesker and said seriously.

Alexander poured a cup of coffee for Qin Tian and Wesker and added his good friends, and continued to record his new research.

"Alexander, you should have changed a little, don't be with that German brat, he can't help you or anything, you're a famous professor." David looked at Alexander and said solemnly.

"He's not a kid, Albert Einstein, he's got a good talent for research, and one day, he's going to shock the world. I'm trying to help him anyway. Alexander affirmed that those were all aspects that they had taken into account.

"Well, you're right! I'm getting out of here. David looked at Qin Tian and Wesker and didn't say anything.

"Alright, Mr. Alexander, let's talk about your problem, judging by your expression, you should have traveled through time and space!" Qin Tian looked at Alexander's haggard appearance and knew that he had used a time machine, so he was not in a very good state.

"yes, how do you know?" Alexander nodded and said seriously to Qin Tian.

"The future cannot be changed, I tried everything, traveled back to the past for a long time, but I couldn't complete the action of changing the past." Alexander said bitterly that there was nothing he could save in the face of Emma.

"In fact, what really can't be changed is the past, and the future can be changed, so why don't you look for answers in the future?" Qin Tian looked at Alexander and said remindedly.

"Thank you, sir, I don't know your name?" Alexander looked at Qin Tian and said gratefully.

"Just call me Mr. Donus." Qin Tian looked at Alexander and said with a smile.

"Actually, you have entered the time refutation, I have some research on you during this time, don't ask me why I know, tell you now! Actually, because of Emma's death, you made a time machine. If she hadn't died, the machine wouldn't have existed. So how do you use your machine to go back in time to save her? You are your tragedy. You Emma's life and the existence of a time machine can only be one or the other. O Alexander! Human beings are small and even pitiful, although sometimes I think they are pathetic. Therefore, it is necessary to use the brilliance of science to change that fate. The secret that Qin Tian told Alexander was also something he knew clearly.

Alexander was very knowledgeable about time, and those were some of the situations they had taken into account, but Qin Tian just looked at Alexander and didn't continue to say anything.

"Mr. Donus, I don't expect you to know my secret. Since no one wants to believe me, I am very happy to know my secrets. Alexander looked at Qin Tian and said with a smile.

"I've been looking at your clothes strangely because I've traveled to the 20th century once, but I haven't stopped. So I understand that you are not simple, but I am not sure that you must be from the future plane. Alexander looked at Qin Tian, shook his head and said, those are all things they know.

"Yes! Time travel, what do you understand? Qin Tian looked at Alexander and continued, those are enough for them to think about, they are rapidly changing everything.

"Time is a very strange thing, as if there is fate and cause and effect." Alexander looked at Qin Tian and continued.

"Then let's go to the future together! Maybe we'll find more answers. Qin Tian looked at Alexander and said encouragingly, those encouragements did have a little effect on Alexander.

"Okay, that's all fine, let's take a look at my time machine first!" Alexander looked at Qin Tian, nodded and said, those situations are what they need to pay attention to, and Qin Tian also needs such a time machine.
