Lu Yu flew over the frozen demon spirit's head, leaving behind a flurry of ice crystals.
The burning ground, the ice crystals scattered in the air, led all the way from the edge of the five hundredth and tenth floor of the Tongtian Tower to the central light beam.
The disciples from the Divine Weapon Pavilion, drawn by the commotion, could only see the traces left by Lu Yu, filled with admiration, not knowing who he was.
The demon spirits, newly entering the half-step Core Formation Realm, could hardly pose any obstacle to Lu Yu, as he slaughtered his way up to the five hundred and tenth floor.
Each half-step Core Formation Realm demon spirit provided Lu Yu with about a million experience points, and by the time he reached the five hundred and tenth floor, he had slain over a hundred demon spirits, accumulating enough of the 50 million experience points required to unlock divine techniques.
