Su Keke couldn't hold back any longer, she looked at Gu Yao, "You are not allowed to be so good to me in the future!" ”

Gu Yao glanced at her in surprise, then laughed, and her ice-like appearance instantly became soft, "Do you still know that I am good to you?" Then I will be content! ”

Su Keke punched the cotton, only to feel that his breath was blocked in his chest, and it was very uncomfortable to not go up and down.

Gu Yao coaxed her like a child, "Do you remember Vika?" ”

This is the name of the E domestic service, everyone has been hiding in his farm, Su Keke plucked a lot of beets from him, of course, it is impossible not to remember.

"Didn't you set out in disguise? Professor Xia's handbag couldn't be empty, so Vika filled it with candy, which Professor Xia brought back. ”

Gu Yao's patient explanation made Su Keke's heart go for more than half of it, she was a little embarrassed, lowered her head and stopped talking.

The car drove into the heavily guarded military headquarters, Gu Yao drove directly to the back, and after passing a heavy sentry, he stopped.

"You go in", Gu Yao pointed to a small brick gray building, "The professor is waiting for you." ”

"Aren't you going in with you?" Su Keke didn't realize that she had subconsciously regarded Gu Yao as her backbone, and her trust in Gu Yao was even more than that of her biological father Xia Heqing.

"No, the professor wants to see you!" Gu Yao also stepped out of the car, "I'll wait for you here, don't worry!" ”

Su Keke slowly walked up the steps and rang the doorbell with a little apprehension.

Xia Heqing came to open the door in person, and he looked very happy, "Good boy, come in!" ”

Later, Su Keke learned that this inconspicuous small building was built according to the standard of being able to resist a ten-magnitude earthquake, and it can be regarded as one of the strongest buildings in China.

"Long Zhan came to see me last night, and he said that as long as I restart my research, I will not be blamed for what I have done over the years," Xia Heqing beckoned his daughter to sit down and made tea for her by himself, "In the future, our father and daughter will never have to be separated again, and they can live here together!" ”

Su Keke frowned, took the teapot in her father's hand, she poured a cup for Xia Heqing first, and then poured a cup for herself.

Su Keke was not as happy as the old man about Xia Heqing's statement that father and daughter would never be separated again, because she had never been with him.

"That's great", Su Keke finally couldn't bear to hit Xia Heqing, she said lightly, remembering the magic pin, "I just have a question for you!" ”

Xia Heqing, like all old fathers, is now eager to give everything to Su Keke, but he has just escaped from country E, and all his property in China has been seized, it is the most embarrassing time, and now Su Keke has a question to ask him, and he immediately replied happily: "Say it!" ”

Su Keke took out the pin, held it in his hand, and pointed to Xia Heqing along the direction of the letters, "Look, these are two letters, S and K, can you tell me, what do these two letters mean?" “

Xia Heqing replied without hesitation: "Of course there is, these are the two initials of time and space, S is time, which represents time, and K is space, do you understand?" “

Spacetime? It seemed that a flash of lightning flashed in front of Su Keke's eyes, but she couldn't catch it.

"But Dad," Su Keke still decided to continue to ask Xia Heqing, "Why is this thing in your hands?" Didn't you say that this is the metal that makes flying machines? Why is it related to time and space? “
