After recovering his spiritual energy, Haoyue rushed out with Lin Xin. Haoyue wasn’t in the same kind of weak state as Long Haochen, and furthermore, with his evolution, his recovery was greatly strengthened. At least until now, Long Haochen had yet to see Haoyue’s limits.
During their fusion, he felt his own body’s limits, and thus couldn’t maintain the fused state with Haoyue.
The reason why Haoyue and Lin Xin rushed out was naturally to reap magical crystals. Lin Xin’s speed of reaction was very fast, but compared to Haoyue, he was still lacking.
Haoyue’s movements were very simple. Rushing ahead, he’d tread on the Jacques Demon corpses to crush them, before engulfing the demon crystals in his mouth.
Although Lin Xin simply recovered the whole corpses, it was still at an inferior speed.
