Arthur wasn't rest assured that everything was fine, so he checked the readings of the sensors to be sure. Then he checked the integrity and placement of the sensors to be sure that they were not giving false readings.
Only after he was sure that everything was fine did he sigh in relief. He checked the energy capacity of the life pill and the energy capacity of the energy stones that he used to charge it.
He compared the two and said, "1,100 units of energy went in, and 1,000 units of energy came out. So that's an efficiency of 90%. I'm glad that something still seems to be efficient in this revised life pill art."
He had used energy worth 1,100 units from the energy stones. In return, the life pill managed to convert and store 1,000 units of it. This kind of efficiency pleased him a lot.
He was also extra proud of himself for succeeding the energy infusion stage in his first attempt.
He said, "It seems I was right. I truly am not bad when it comes to formation engravings."
