Can you recommend a novel that I've read before?

I don't remember the name of the author or the main character. The main character seems to be surnamed Ren.
It's probably about an online game
The only thing he remembered was that a large inter-universe game company had bought a planet as the blueprint for a game. If the person inside died, it would be impossible for him to live again. The protagonist was a Chinese man. One day, when he was playing a game at home, he suddenly received an invitation to play a game on his computer and asked if he wanted to go. The protagonist went and was sent to another planet. In this game, each person could choose a skill! The main character seemed to have chosen the strategy of the military counselor. There was no need to upgrade it.
He remembered that the main character was first alone and then met a team. The team leader chose the skill Double EXP, but the game didn't need to level up, so his skill was useless. However, he was quite optimistic. After that, it was the main character who had overcome danger with them again and again. I remember that the place I saw was where the main characters were enemies with a country made up of five people. The five of them were leaders, and one of them had a skill that seemed to be able to summon a person to her side. The time limit was either once a day or once a month.
