Ye Feng thought quickly, but he still did not act rashly, instead, he conducted the next round of tests.
Next, he planned to conduct a set of comparative tests.
He called over another Second Order Mutated Buffalo as well as one Second Order Mutated Sparrow.
He had them both ingest Second Order Life Fruit before entering the forbidden zone together.
By comparing the two, he would be able to know if his own defensive power had any resistance against this mysterious energy.
Soon enough, the Mutated Buffalo and the Mutated Sparrow were driven inside.
The Second Order Life Fruit contained limited Life Energy, so the Mutated Buffalo only lasted about 3 minutes before fleeing the forbidden zone.
This was within Ye Feng's expectations.
However, the seemingly weaker Mutated Sparrow stayed behind.
And it wasn't until the 9th minute that its Life Energy was entirely depleted, and it escaped.
This scene left Ye Feng somewhat baffled, completely unsure of what was going on.
