Lin Fan revealed a faint smile when he saw this.
Naturally he knew what Ling Tian was thinking, so he didn't waste any time as he started charging at Ling Tian, taking advantage of the fact that he was caught off guard.
When Lin Fan moved, the barrier around him moved along with him, smashing into Ling Tian's domain.
As the barrier and the domain clashed, Ling Tian was shocked to find that he was getting slightly pushed back by the barrier.
This pulled Ling Tian out of his shock and he increased his power, increasing the pressure of his domain and pushing the barrier back.
When Lin Fan saw this, he immediately moved back again and brought the barrier away from Ling Tian's domain. It seemed that even with this barrier, he didn't have a proper way to deal with Ling Tian's domain.
As for what this barrier was, it was a pseudo domain that was formed from the various laws that the Nascent Soul Realm beasts injected into the array.
