Charging Crash Gu

Horizontal charge Gu and vertical crash Gu are the two main materials. With those rank three Gu as the main, plus primeval essence and supplementary materials, he refines charging crash Gu. Two days later he succeeds and obtains it as a new rank four Gu. The two rank three Gu together charge only a hundred steps. The fused Gu raises that distance to two hundred steps and halves the delay between repeated uses, with a slightly higher primeval essence cost. He activates it when charging toward the peak after the three kings inheritance has opened. ^{ch. 345}

After a battle where he used four arm earth king killer move and flew almost the whole time, he judges that flying is much more convenient than charging crash Gu and poses a higher threat to enemies, so with master level flying attainment he should make full use of that superiority. ^{ch. 543}
