It took a total of five months for the IS Demon Angel to go from design to construction to completion, but Su Du did not stay in the world of "Infinite Stratos" all the time during these five months, and occasionally he would return to the main world and make some contact with the outside world, indicating that he did not mysteriously disappear, and because of such frequent back and forth, Su Du discovered another function of the dimensional shuttle, that is, the change in the number of cause and effect points. Pen "Fun" Pavilion www.biquge.info

The causal point of the original meta shuttle, after Su Du put five cameras, only a pitiful single digit remained, but after these several crossings, Su Du found that every time he returned to his own world, the cause and effect point would increase a lot out of thin air, and later through experiments, Su Du found that once he created an "influence" in the two worlds, it would lead to the growth of cause and effect points, especially in his own world, the growth rate of cause and effect points was even faster. It is precisely because of the growth of the causal point that Su Du has the capital to bring back his special machine. For the same reason, Sudo was able to launch a new observation device in the four different worlds he discovered, an unmanned observation plane designed and built by Chloe, the assistant of Shinoshinoshu, with a variety of functions such as intelligent flight, photographic recording, and collection and sampling.

Su Du, who got the new equipment, naturally immediately eliminated the old-fashioned camera and replaced it with a new drone to observe the four different worlds.

After such a long time, Su Du also has a better understanding of the other four different worlds.

Alien World No. 1 seems to be a ruined world after the World War, where many creatures that Su Du knows, but there are also a large number of mutated products, and so far, Su Du has not found any trace of humans; In the second different world, in addition to zombies, Sudu also discovered the existence of lickers and zombie dogs, which can basically be confirmed to be the world of "Resident Evil"; Alternate World 4 seems to be a parallel Earth around 2009, but Su Du has not found any information he is familiar with, and he cannot determine what the specific world is for the time being; Alternate World 5 is the age of the use of ancient firearms, and based on the human clothing found so far, it is speculated that it was around the seventies and eighties of the 19th century.

For these four different worlds, because of the crossing wind guided by a certain point, Su Du originally planned to go to the world of "Resident Evil", but through the information obtained, this world has obviously broken out Resident Evil, and it is not the beginning of the plot that Su Du is familiar with, and Su Du has one of the biggest worries about entering this world, that is, what should he do if he is infected with the T virus and the vaccine does not work for people in other worlds? Even if Sudo himself is not infected with the T virus, what if he accidentally brings the T virus back to this world and triggers the Resident Evil of the Overworld? The various special drugs that come to this world cannot kill the T virus from another world.

Thinking of this, Su Du was shocked, after all, he is not the kind of little expert who knows that something is in great danger but does not know whether he is alive or dead, he has to get his hands on it, Su Du recalled that he has recovered the observation device from this world many times, although he did not bring back the T virus, but it is more likely that the observation device has been properly sterilized and disinfected in the process of passing through the space-time gate, but, what if it fails to successfully eliminate the T virus carried by it? Thinking of this, Su Du felt uncomfortable, and at the same time secretly decided to temporarily block the world of "Resident Evil", and never travel through the past without absolute safety.

Resident Evil World Exclusion; For the time being, the fourth world seems to be not much different from Sudu's world, and it is not interesting to travel through the past, so it is also excluded. The rest of the No. 1 and No. 5 different worlds, Su Du decided to travel to the No. 1 different world after consideration, because he is more familiar with this world, and this is a ruin that has experienced the world war, maybe there will be some useful ruins left somewhere waiting to be excavated, but the main reason is that after Su Du got IS, he decided to return to this world that once made him wolf run wild, and clean up the bugs that once made him mess and urine.

In some ways, Sudoke is a very cautious person.

However, before Su Du opened the space-time door to the No. 1 different world, his mobile phone suddenly rang, Su Du opened the mobile phone with an unhappy expression on his face, but he retracted after seeing the name of the communicator on the screen.

"Mom, what's wrong?" The caller was Sudu's mother, an ordinary housewife who retired at home.

"Well, Xiaodu, I'm fine, it's just that you haven't been home for a long time, and your dad and I miss you a little. How have you been working lately? The body is fine! What about eating? I remember you are the most picky, it's not as picky as at home, don't be too picky......" Su's mother babbled, Su Du silently listened to her mother's words of concern, and a warm current crossed her heart.

"Mom, I've been doing well lately, I've been living and working well, I'm in good health, I'm eating better, so don't worry too much." Su Du talked to his mother lightly, but in fact, Su Du had already resigned from his job, and Su Du, who had a certain amount of self-preservation and traversing ability, no longer had any interest in the iron job of getting a dead salary from 9 to 5, but Su Du still hid his family from his family about his resignation, so it is not easy to tell Su's mother here for the time being.

“…… Xiaodu, if you're tired outside, go home! With me and your dad, there is no shortage of bowls for you to eat at home. At the end of the call, Su's mother wanted to speak and stopped, but finally said so. This also made Su Du vaguely aware that his parents seemed to know about his resignation.

In the eyes of Su's mother, who didn't know, Su Du who quit her job threw away the iron rice bowl by herself, but for the reason of taking care of Su Du's self-esteem, she didn't mention it directly, but just used her own way to support and care for her son. However, this conversation also made Su Du realize that although he had the ability to travel through time, he still had family in this world, and he couldn't ignore them.

Su Du didn't plan to disclose his specialness, but now he, in the eyes of others, is simply a jobless vagrant, even if Su Du himself doesn't care, but the parents who don't know anything may be working silently for their son, after they heard that Su Du resigned, the biggest possibility is to be angry, but after being angry, he must be looking for another job for him and asking his old friends for help, begging the old leader to help. Thinking of this, Su Du couldn't help but feel ashamed, he actually neglected his parents.

"Maybe you should learn like those who traveled through the seniors, and first become a ......master of time and space," Anyway, Su Du thought that he should let his parents live a better life, instead of letting them worry about their sons at an age when they should be raising themselves.

This idea of overthrowing the master at that time came out of his life, and all kinds of ideas appeared in Su Du's mind, whether it was the No. 1 or No. 5 different world, it seemed that it could be used as a dumping ground for the goods of this world.

After having such a thought, Su Du suddenly had some more plans in his heart, but he still didn't bring any extra items other than IS with him this time, because these things need to consume cause and effect points, and Su Du does not have enough cause and effect points for the time being.

The next moment, Sudu appeared on a wilderness, the environment here was similar to the Gobi Desert, surrounded by endless yellow sand, and a few huge rocks stood in the distance. Judging by the position of the stars in the night sky, this is Pennsylvania, USA, but what catches Sudo's eye at this time is not the beautiful environment of Pennsylvania that he remembers, but the feeling of the Sahara Desert.

With dry sand under his feet and gray air in his mouth, this world does not feel good for Sudu, compared to the world of "Infinite Stratos", although it is also the earth, but it unexpectedly gives Sudu a feeling of a real different world.
