What Lu Chao had just explained was something he had already tried on his first trip to the Azure Flame Sect's Forbidden Land.
He naturally had to explain it clearly to Sun Shijin. Namely... when breaking through each floor, the person following him into the Illusion Realm must not use any True Qi, or they would be unable to proceed.
Without another word...
Lu Chao and Sun Shijin passed directly through the barrier of the first floor.
Sun Shijin felt as if he had entered a void, an illusory world. Before him was a vast expanse of white, and it seemed he had to communicate with something to break through the Forbidden Land's first floor.
He subconsciously glanced at Lu Chao beside him...
But Lu Chao had already begun to act. He connected with the Soldier Dao aura of the Illusion Realm.
The Illusion Realm activated, and a Soldier Dao Battle Array appeared before Lu Chao. He then began to solve it with practiced ease.
