Foreword & Extra、Where should we go through?

In today's day and age, the protagonists of all kinds of novels seem to have made time travel commonplace - as soon as they open their eyes, they find a place with a completely different scenery, and at most they think about whether they are making a movie, and then immediately decisively think that they have crossed over.

Moreover, no matter how failed and decadent the protagonist's previous life was, as long as he crossed into a different shijie, he would quickly break away from the original attributes of a small citizen or an otaku leftover woman, and he would not hesitate to be fierce - weishenme felt that the plane where the protagonist was located, as if there was often such a thing as crossing over?

In general, it is a sentence - after the crossing, the protagonist must quickly adapt to the environment and develop quickly! Since they have all been crossed, isn't it unscientific to be underdeveloped?

Alas, from this point of view, the adaptability and fighting spirit of the protagonist are really not ordinarily strong!

But here's the problem...... Is life after crossing through so easy for us modern people to adapt to?

Due to the variety of fantasy shijie's settings, and the race that crosses the possession, there is everything from gods to demons to skeletons, and it is really difficult to compare the living comfort of these fantasy creatures on the same level. Therefore, in this article, we will first focus on the most conventional type of historical crossing, and make some serious scientific assumptions and discussions on the various situations encountered by modern people after crossing history.

- Uh-huh, I've always liked things like shattering other people's beautiful fantasies!!

In general, it is not a comfortable choice for modern people to travel to ancient times, even if they travel to become the children of the powerful.
