Transmigrating into Delta Force: Havoc's Nano Vanguard

I try to update this book every day, but I will develop each book according to my own vision. I ended it hastily. In fact, I really wanted to write that the protagonists defeated the high-dimensional creatures, but it was impossible in terms of the world view. The setting of the high-dimensional advent is because the delta world has come to reality, so it is impossible to defeat. I can only end it hastily with the protagonist self-destructing, but this does not mean that it will not work later. . .

Very good hope to continue
