After the couple returned to the space, Xu Jianguo directly told Wen Sitian his thoughts.

According to his plan, as he successfully completed the retirement procedures and obtained the re-employment certificate, he would definitely not be able to realize his dream of traveling around the world with Wen Sitian in the next few years.

Moreover, given the couple's status, it would be a no-brainer for them to apply for passports and travel abroad as civilians.

So Xu Jianguo planned to make use of the substitute servants that he had not been able to use before to see if they could really imitate him completely.

If he could do it, he would leave two substitute servants to replace him and Wen Sitian, and then go through the space portal, take the identity documents he had applied for in Hong Kong Island and travel around the world.

And because of the existence of space, even if something happens in Jingzhou, they can rush back as quickly as possible.

Wen Sitian was still a little worried about Xu Jianguo's bold idea.

However, out of trust in Xu Jianguo and her desire to go for a walk outside while they were both in good health, she nodded in agreement.

After unifying his thoughts, Xu Jianguo summoned two substitute servants who were still in their original, unactivated state through the system control panel in his mind.

As an order was given, the eyes of the two servants suddenly lit up, and then they stood in front of Xu Jianguo and Wen Sitian respectively.

Immediately afterwards, the light in the substitute servant's eyes began to become brighter and brighter, forming two light blue beams similar to scanning rays, and began to scan the target standing in front of them.

And something even more surprising happened. As the scanning rays began to slowly move downward from the tops of Xu Jianguo and Wen Sitian's heads, the appearance of the two substitute servants also began to change, little by little becoming the appearance of Xu Jianguo and Wen Sitian.

At this moment, Xu Jianguo and Wen Sitian's eyes were filled with surprise, and they felt that the ability of this substitute servant was indeed powerful.

Just like that, as the light blue light slowly scanned across the entire body, two "people" who looked exactly like them appeared in front of Xu Jianguo and Wen Sitian.

At this time, the two "people" were naked, and the birthmarks, scars and hair on their skin were exactly the same as Xu Jianguo and Wen Sitian, with no flaws visible.

Even though both of them are now in their sixties, because they had taken gene-enhancing drugs before, time has not left too many traces on their faces and bodies. The couple now looks only about forty years old.

Moreover, even when compared with young people, their physiques still give them an advantage that can crush everyone else.

It is precisely because of this that just looking at this scene in front of them inevitably makes the couple, who have known each other and been together for decades, feel a little embarrassed.

Wen Sitian's pretty face had already turned red, which made Xu Jianguo think of the scene when they had just gotten married, and he couldn't help feeling a lot of emotions.

But before the two of them could make any move, the two substitute servants standing in front of them began to take the next step and stepped to the side of the two of them.

It was not until the pale blue light shot out from the eyes of the two "people" again that Xu Jianguo and Wen Sitian discovered that their sides were still shining with metallic luster. It was not until then that the couple realized that the scan of this substitute servant should be all-round.

Half an hour later, the substitute servant's scanning work was completed. According to the prompt of the system in his mind, Xu Jianguo sat down with Wen Sitian.

Immediately afterwards, two substitute servants came behind them, raised their arms, and gently placed their index fingers on the temples of Xu Jianguo and Wen Sitian.

When their fingers touched the skin, the couple did not feel any coldness, it felt exactly the same as touching normal human skin.

According to the system's explanation, the substitute servant at this moment is receiving the couple's memories, life, movements and language habits through electromagnetic waves of special frequencies, so as to be foolproof when imitating the two in the future.

(Those who have read this, please don't rush to complain. As mentioned before, the underlying logic of substitute servants is that they must not disobey the host's instructions, so there is no need to worry that they will do anything to rebel against Tiangang.)

Just like that, another half an hour passed, and suddenly a system prompt sounded in Xu Jianguo's mind.

[Ding, the substitute servant has completed replication. The host can issue the activation command through the system panel! ]

"Is that the end?" Xu Jianguo asked.

[Ding, yes! In addition, the host can also set special event trigger keywords for the substitute servant. For example, after encountering specific people and events, the host will receive a system prompt so that the host can handle it personally!]

Xu Jianguo thought about it and understood what the system meant. He had to admit that the system was indeed very thoughtful.

After thinking for a moment, Xu Jianguo used his mind to set several trigger keywords for special events in the system.

Names like Su Dingshan, Wu Tianlong, Wang Huaian, Old Man and Grandma Deng are all special words. These elderly people are already very old. Xu Jianguo doesn't know how much time is left for them, but he is still a little worried. Moreover, he has recognized several of them as his godgrandfathers, so if something happens to them, the couple will definitely rush back as soon as possible.

In this way, Xu Jianguo and Wen Sitian took almost an hour to prepare their own stand-ins. This means that from now on, the two are free men and can start their plan of traveling around the world at any time.

However, because it was the first time for the couple to use a substitute servant, they were obviously still a little worried. So after discussing it, they decided to test it on their children at home first to see if their closest people could spot the flaws.

After the two men changed their clothes, the substitute servants immediately put on their clothes. Then, after Xu Jianguo issued the start command through the system panel, the two "people" disappeared directly in front of them, left the space and returned home.

At this time, the couple had already arrived at the study in the courtyard.

Xu Jianguo used the system panel to project the images seen by the two substitute servants onto the monitor so that he and Wen Sitian could watch them.
