Space Tunnel connected to Vearth.
Zhi Yue and Zhi Yang had contacted the people of Vearth to create a space tunnel to temporarily connect the world they are in and to Vearth. This is a special technique only the Hei Clan is capable of. Under the command of the God of Space, Hei Jue, this space tunnel was made to welcome the group. Normally, they would only use a direct teleportation door which instantly leads to the one in the Nether System.
But per request of the God of Destruction, Hei Anjing, to his cousin, Hei Jue, this special tunnel was made. The reason for this is for the former King of Beast to remember the routes that will bring him back to Vearth. After all, he is a field agent that will most likely live outside looking for traces of chaos energy all over the universe. It would be safer for him to know the path and danger in the space he would have to tackle in the future.
