Нихайчунфань, 逆海崇帆

Many years ago in a small village ruined by war, 鸠神练，弁袭君 and 杜舞雩 took a oath of their brotherhood. Then a new religious organization was founded, aiming at to bring peace and hope to people who are suffering. The hard will and the strong motivation of 杜舞雩 impressed 弁袭君 a lot. To the latter оne, their organization became his family and the reason to live, and he found himself very happy chasing for dream with his friends. But 杜舞雩 noticed its bad influence, as they became sorts of organization that always achieve their goal in some extreme way. Then he started to doubt about all.
The adoration to 杜舞雩 of 弁袭君 gradually turn into a secret unrequited love. He began to envy her sister, for it made him crazy to see 杜舞雩 accepted the love from others, while she and 杜舞雩 really loved each other. So finally he cursed his sister, and she jumped from the stairway just like it’s an accident. 杜舞雩 became more disappointed and doubtful about the religion. Later 杜舞雩 asked 弁袭君, “if you calls it miracle, so why can it treat your sister”? He just can’t reply.
绝望之刀 was оnce saved by 画眉, and he believed her death was schemed by 杜舞雩. So he showed open hostility to him.

»Поэтому я сразу подумала, что 逆海崇帆 более-менее подходит под привычное определение секты)
You're right. And it turned out this organization became nothing but a tool of 鸠神练. She used it to satisfy her individual ambition.
But all these characters live in a fantasy world, so they do have some abilities can be called as miracle. 鸠神练 used a huge magic circle to cover the sun for a long period. And 弁袭君, he made a girl transform into a boy, which impressed 慕潇韩 a lot XDD That's hilarious. So they didn't lie to their believers in that way, but they really didn't care about the misery or life of the believers. They poisoned in river and provide medicine to people who were willing to join their organization. They covered the sun, so the monsters and zombies which used to show up in nights now began to hang in the streets all day. And they provided holy fire to people, in order to get more supporters.

о смерти Ду Уюя и заговоре Бянь Си с Шиянем

When 弁袭君 and his organization sacrificed disciples and finally made their way to 黑海森狱, he suddenly saw the dead body of 杜舞雩, lying оn the road with nameless corpses. He got shocked by this, and lost his peace for a long while. He had been kept this love secretly for many years, waiting for another day he can stay next to the man; now his love was gone, and he felt he just can’t take it. He wanted to bring him back from the Death. He said, “Without you, the world is just a place so bleak and desolate”(没有你的人世，太凄凉了).
But the thing is, by that time he was lack of assistance, his magic оnly can make the corpse stop decompose. As for the his colleagues, 鸠神练 disband the whole organization, and refused to help. She intended to kill 杜舞雩, because he secretly destroyed their every plan. Then 古陵逝烟 came, he said he had a magic item, the ball called 造化球 he usually hold in hands, can revive 杜舞雩. But when they tried to use it, they were interrupted by 意琦行, so it didn’t succeed. And 弁袭君 watched the corpse burning in fire.
Then he wished to take revenge, but 凉守宫 exposed the scheme for him: 古陵逝烟 actually didn’t have the power to revive anyone, and also he won’t save 杜舞雩. He made 意琦行 appeared оn purpose, and faked it as an accident, aiming at enraging 弁袭君. He expected the latter would kill 意琦行 for him.
So now 弁袭君 would like to make this fraud pay. But at the end, he was betrayed by another big liar — 一色秋… When he fell оn the ground and closed his eyes, he said, “祸风行, did I repay everything I owe you?(吾还你了吗)”
