This sudden turn of events startled Philip. He looked at the mark on his arm. That change only happened for an instant before it became motionless again. Did it sense its kind? Philip frowned. The others did not notice this but stared at the stone door that was already open. After the forces entered the door one after another, no one could be seen, and not even a sound could be heard. It was as if the space behind the door was an abyss that devoured everything. After waiting for a while, Philip was about to enter the door. At this moment, a figure shrouded in a black robe suddenly appeared on a platform beside them. This person in a black robe watched as Philip and his party walked through the door and entered the deep space. At the moment he entered the door, Philip turned back and saw the figure in a black robe. It was a very strange and familiar feeling. “Did you see that guy over there?” Philip asked. Fennel and the others looked back and shook their heads. Whoosh! With a bright flash, Philip and the others appeared on a very ancient battlefield. They were surrounded by broken walls and ruins, and the ground was full of withered bones. This place was gloomy with a blood-red setting sun and clouds on the horizon. After Philip and the others landed on the ground, they felt that this place was different from the outside world. Lord Ludo said immediately, “It’s an alternate space!”

“Alternate space?” Philip asked with a frown. Lord Ludo frowned and said gravely for the first time, “Yes, it’s an alternate space! To explain with the current scientific concept, it’s the opposite dimension of space! This alternate space has always coexisted with the real space, but it requires a strong technical force or a strong power of rules to open the door of the alternate space! Now, the only ones that can open the alternate space are our country, County M, and Country Y. It’s the highest symbol of scientific and technological civilization.” After that, Philip frowned and asked, “What is the alternate space used for?” Lord Ludo frowned and said, “It’s used to train special beings and detain some special prisoners! There’s an alternate space in the Heavenly Court too, which is used to detain some special beings found by the Heavenly Court over thousands of years. If I’m not mistaken, the alternate space in this Mystic Cave should be used to detain the group of creatures from the other shore that wreaked havoc in our country back then!” After Lord Ludo finished speaking, Philip and the others became very solemn. Philip looked around and found a pre-Kai symbol on a ruined wall. Was this the battlefield where Emperor Kai led a million armies to face the creatures from the other shore? No wonder it felt so familiar… Philip had felt and sensed this in the space tunnel!
