Lu Hao gazed at the brain core with mixed feelings. It had appeared so easily, yet humanity had spent over a hundred years researching without ever discovering it.
That was why human progress slowed after reaching Rank Seven. They could only gradually increase their mental power over time. It also meant that high-ranked human martial artists had no way to substantially increase their mental power, leaving them unable to condense indestructible matter at Rank Eight.
Otherwise, with indestructible matter, there would not have been so many grandmasters killed in battle.
One sentence of true teaching was worth ten thousand volumes of false scripture. Then Lu Hao began channeling power through the Three-Focus Gates to temper his brain core.
He opened all three Three-Focus Gates a crack. After reaching Rank Seven, he could open and close them at will.
Three kinds of power—vital blood, mental power, and life force—seeped out of the three gates and began converging on the illusory speck of light between them.
Under the tempering of these energies, the brain core began undergoing subtle changes. Lu Hao also felt a refreshing coolness in his head. The brain core was clearly inside the Three-Focus Gates, yet it was connected to his brain. How strange.
No wonder humanity had failed to discover it after a century of research. They had probably spent that entire century studying the brain. How could they have imagined that the brain core was actually inside the Three-Focus Gates?
Tempering his brain core felt very comfortable, like wearing an icy-cool hat. After tempering it for a little over half an hour, Lu Hao sensed a slight fluctuation in his mental power.
He opened his panel and checked. His mental power limit had increased by one hertz.
One hertz sounded like very little, but this was only
