Fourth Lian is a death soldier of the Lian Family. Generations before, he had been fed drugs and brainwashed for generations. He is not loyal to Luochen Sword Palace, but loyal to Lian Yichen personally.
When the Holy Emperor Venerable began to eliminate dissent, Lian Yichen was already making such preparations. The chaos caused by the Demon Emperor centuries ago gave him a slight chance. At that time, he took advantage of the internal chaos among Modern Cultivators to fabricate a family on the Shenzhou Continent. Those death soldiers are special humans who have been long-term drug brainwashed with no personality. Then, over the centuries, he continuously sent brainwashed mortals to reintegrate into that family to maintain his control.
During the chaos of the Demon Emperor, most families were completely wiped out, and some historical gaps appeared, leaving the entire Shenzhou in chaos. This was indeed the best time to leave a "back road."
