God of Time Travel Cheat Device

Chen Rui, who has lived in the earth world for seventeen years, came to the Roland Continent in a different world during a failed time travel, and was reborn as Chen Rui, a companion of the Chen family. Let's see how he, who has not gained the halo of the protagonist, hugs the protagonist's thigh with the help of a portable plug-in, and connects the plug-ins as the second male lead; as a supporting character, he follows the protagonist to level up and fight monsters, slay alien beasts with his sword, step on geniuses, travel across the entire different world, and make his own path among thousands of races. What's so good about the protagonist? He went through many hardships and narrowly escaped death. With the plug-in, why not let the protagonist let you? When the protagonist's road comes to an end, it is time for Chen Rui to exit the stage. Let's see where he finally chooses to go after he is already at the top.
