In the center of the underground training base, there was a gigantic control center where almost ten thousand blinking light beams were floating in the air.
Meng Weiyang, Sha Tianqing, and Yan Ba, three Nascent Soul Stage Cultivators, were observing the constantly-changing pictures solemnly.
In some of the light beams, the 61 Orb Patrollers were soaking in the strengthening drugs, holding their breath, and meditating.
The light beams around those ones displayed the status of their muscles, nerves, veins, and bones layer by layer as if the scenes had been shot using a fluoroscope.
Complicated data was pouring on still other light beams, which displayed the vital signs of the Orb Patrollers. They even included the change of hardness of the Orb Patrollers' cells.
If anyone went senseless, they would be treated within the next half second.
