Su Yichen was slightly surprised, as an artificial intelligence, Su Li can control the slightest strength and accuracy, which is not too surprising, even if a highly skilled chef can easily dispose of the tofu shreds placed on the rice paper with a kitchen knife, without destroying the rice paper in the slightest. Su Yichen was surprised by the knife in Su Li's hand, the technology of the high-frequency vibrating particle knife was obtained from the Pluto base, but Su Yichen had never used this technology, but only brought the technology back to Earth from the Vanguard, who would have thought that Su Li would actually build a physical object by herself according to this technology.

After taking this knife from Su Li's hand, Su Yichen took a closer look, and had to admit that Su Li's design and manufacturing were extremely perfect, the whole knife was almost as beautiful as a handicraft, the streamlined knife was extremely comfortable to grasp, and on the inside of the knife handle, Su Li also designed an ingenious device to control it.

"Nice weapon, what material is used for the blade." Playing with it, Su Yichen asked.

Su Li told him that the blade of the knife was made of a special metal found in the Pluto warehouse, so the entire blade looked ordinary, but it was indestructible in high-frequency vibrations. Even the main materials used to build the base could not stop the knife from cutting.

After liking Su Li a few words, Su Yichen felt that the knife she made was a good defensive weapon, and then thought that the Pioneer was about to return to the Pluto base, Su Yichen gave Su Li a task, which was to make a few more such knives for everyone to equip. Hearing Su Yichen's instructions, Su Li was very happy and agreed in one bite.

A few days later, the returning Vanguard approached Pluto, and Su Yichen, who had been prepared for a long time, still used the original way to cover for the Vanguard, in case Hades and even the Southern Cross visitors found out.

The modified Vanguard was twice as fast as before, reaching Pluto's orbit 72 hours later.

"Pluto! I'm the Pioneer! I'm the Pioneer! We're back! ”

A call from the Pioneer came from the control room. This voice Su Yichen heard very clearly, this was Lin Guodong's voice, and he returned to Pluto with excitement and excitement.

Then, the voices of Mo Liwen, Gu Chen, and Gao Jian also appeared, and everyone on the Pioneer gathered together again. Not only them, but there were more than a dozen members who came to Pluto with the Pioneer this time, including researchers from the 781 Center and military technicians. They are all elite personnel who support the Pluto base on the earth side, and the chief considered that Luo Yan was also at the Pluto base, so he specially selected several outstanding female comrades to participate in the staffing.

The order was given, and the base system controlled the Vanguard, and then transmitted the Pioneer from low earth orbit directly to the interior of the base. The original members of the Vanguard who had experienced two teleportations were very indifferent to this, while the others were extremely shocked. One moment they were still in Pluto's low-earth orbit in space, and the next moment they actually entered the interior of the base, and in just a moment, it was like a trick.

"Su Li, you go and get them." Su Yichen instructed Su Li, Su Li jumped away in response, and after a while, Su Li came to the square, and the huge Pioneer had stopped there steadily.

The first person to come down from the Pioneer in a spacesuit was Gao Jian. When he walked down the gangway and saw Su Li, who was looking up at them, he was stunned for a moment, showing a puzzled expression.

Su Li, who was standing in front of Gao Jian, was wearing an ordinary jacket and jeans. There is a metal belt around his waist, a short knife hangs on the belt, he is not tall, and he has a beautiful appearance of a teenager with a little baby fat, like a big junior high school student, and his bright big eyes are looking at Gao Jian.

Gao Jian is very clear. There are only two people in the Pluto base, Su Yichen and Luo Yan, when did there be a third person? It only took them a little more than a year to leave the Pluto base and then return, and even if Su Yichen and his wife had a child in such a short period of time, it would still be a baby who was still nursing. But where did the girl in front of you come from? What's even more strange is that her appearance obviously bears the shadows of Su Yichen and Luo Yan.

"You...... You are......? ”

Gao Jian took a step back vigilantly. Could it be that the Pluto base has been taken over by aliens? Is this girl an alien? And it wasn't Su Yichen and his wife who landed them before, all of them fell into the trap?

"Hee-hee......." Looking at Gao Jian's vigilant appearance, Su Li couldn't help but be happy, tilted her head and said, "Gao Jian, you don't know me anymore?" Guess who I am. ”

"How do you know about me?" Gao Jian was even more surprised, he never had the impression of this girl in his memory, but the other party called out his name in one mouth.

Su Li said very proudly: "Of course I know you, not only you, but also Lin Guodong, Mo Liwen and Gu Chen, you guys came back too late, do you know that we have been waiting for you for more than a year." ”

"You...... You....... "Gao Jian never thought that this girl would know everyone before their Pioneer, and she also said that she had been waiting for them for more than a year, could it be that this girl was Luo Yan'......? No, no! This is absolutely impossible, although her appearance is seven or eight points similar to Luo Yan, she obviously looks like Su Yichen in her eyebrows. Thinking back to the word "we" she said, Gao Jian suddenly remembered a possibility, he thought that in addition to Su Yichen and his wife staying at the Pluto base, there was indeed a "person" left here.

"Are you Su Li......?" Gao Jian asked tentatively.

Su Libian flattened her mouth: "It's really boring, I actually guessed it for you." ”

"Are you really Su Li? You...... How could you ......? Gao Jian stared at the incredulous eyes, although he guessed the girl's origin, but he was extremely shocked in his heart.

"Hee-hee, how am I doing this compared to before?" Su Li turned around in front of Gao Jian and asked proudly.

The surprise on Gao Jian's face was still there, but he nodded subconsciously. Su Li was talking to Gao Jian with a smile, and just after saying a few words, she tilted her head and said to Gao Jian: "Dad is urging us, Gao Jian, you come with me, Dad and Mom are waiting for you over there in the ecological balance circle." Oh, by the way, you've already arranged your place to stay, I'll take you there later. ”

Su Li said and beckoned to Gao Jian and the people who had just gotten off the spaceship one after another, and jumped up and down to lead the way in front. Gao Jian didn't ask much, and directly beckoned everyone to follow Su Li. Those who came to the Pluto base for the first time were very curious about the interior of the Pluto base, and looked around all the way, and one of them suddenly remembered something and asked Gao Jian: "Didn't the captain say before that although the air here can be breathed, it's better to wear a spacesuit?" ”

Gao Jian nodded, and explained that there are only a few places inside the base where you don't need to wear a spacesuit, and in other areas, it is better to wear a spacesuit for the sake of health.

"But what's wrong with this girl? By the way, shouldn't Director Su and his wife be here, why are there more girls? Who is she......? The other party asked strangely at Su Li, who was walking in front, suspiciously.

Gao Jian shook his head with a smile and didn't explain much, just patted the shoulder of the person who asked and said, "She is different from us." (To be continued......)

PS: As for the question of light years, I have considered it in my writing, according to the normal world, the universe that human beings see is the universe of the past, and the farther away the starry sky, the longer it is from the present, which is the result of the speed of light and distance. So the Hades observations can't be a lie, because there is a reason, and this explanation will be mentioned in a later chapter.
