This was because he had only manufactured so much TNT explosives, taking out all his stockpile for this one operation.
Each kilogram of TNT could generate 4.2 million joules of energy; the terrifying power generated by the immediate explosion of more than two hundred tones of TNT was the largest explosive force that Li Shiming had ever detonated.
Even for this explosion, he had set up sensors inside and outside his cave dwelling in order to collect data from the explosion.
With this data combined with the reaction of Patriarch Weng Zhao, the threat effectiveness of TNT explosives against cultivators could be analyzed.
Just as Patriarch Weng Zhao was preparing to break the formation, the explosion occurred. It was initiated from all directions at the same time, with many detonators triggered at the same moment under the precision control of an internal controller, remotely operated by his life-bound magical artifact IBMz15.
