Countless questions floated in Yang Kong's mind, yet he could not figure any of them out.
He instinctively stood beside the gene tester, watching the scene with a dull face. He saw the painful expression on Tang Ling's face, but it was suppressed by the tenacity that he showed.
He saw a line of blood trickling down the edge of Tang Ling's mouth.
He saw Tang Ling's body shaking vehemently.
He saw sweat drenching Tang Ling, even wetting the floor around him.
Yang Kong wanted to switch off the genetic tester for numerous times, but what use would it have? With Tang Ling's powerful spirit, he might not even need the genetic tester to enter the visualization state again, he could continue gathering the energy.
It might consume a longer time, but since the kid insisted on it and was serious about cultivating, why would Yang Kong waste his time?
