As soon as he saw the gateway, Tang Mu had a suspicion. Although the energy fluctuation on the gateway was very faint, he still noticed an extremely strange change there, as if it were the entrance to some other place. Now the surrounding environment had changed, which meant they had entered a place similar to a Virtual Realm.
He had just seen a figure standing inside the gateway, but after passing through it, there was no one to be seen. He wasn't sure if the person had left or if they were never there in the first place. However, there was nothing particularly special about the change in the environment here. If it continued to resemble going up a mountain, it might even deceive some people.
