Clang.
There were hundreds of spacetime crystals in the fourth secret chamber. Although they were all ordinary spacetime crystals, they were indeed spacetime crystals and were very precious.
Back in the Celestial Pole Mountain Range, Lin Feng had almost swept through the periphery of the Celestial Pole Mountain Range, and only obtained a few dozen ordinary spacetime crystals. But now, there were hundreds of spacetime crystals in the secret chamber. It was unbelievable.
Even if ordinary spacetime crystals might not have much of an effect on Lin Feng now, he definitely would not mind having more spacetime crystals. After all, spacetime crystals were the "hard currency" in the Origin Gate, and had considerable purchasing power.
Of course, Lin Feng had no intention of taking them all himself. The two of them each obtained about 300 spacetime crystals, which could be considered a huge gain.
