A powerful, black-colored sword slash filled with the Dao of Lightning escaped from the black sword, as it flew towards the barrier of knowledge in front of Shun Long.
However, the moment that the black-colored slash touched the barrier, the azure barrier barely rippled, before the sword slash lost all of its strength and quickly disappeared.
It looked no different than a small rock being thrown into the sea, barely creating any waves in the process.
Shun Long however didn't seem disappointed when he saw the scene in front of him.
Instead, it seemed as if he had already expected this, as his lips curved up into a smile.
Of course, how could a barrier that could contain information about tens of thousands of martial skills and cultivation techniques, be harmed by a single sword slash at the early Nascent Soul stage?
