Funeral and Spread of Buddhism - Break the Hell 破地狱

Normally Chinese funeral ritual combined with Taoism and Buddhism and there is something call break the hell ritual. Break the Hell Ritual I had noticed the ritual Sifu before recited the Original Vows of Ksitigarbha Bodhisattva Sutra so i did ask him some of the basic like first statement below and he is unable to answer means likely the ritual being non effective so i dont plan to hire any of them and it's very expensive too. 無 上 甚 深 微 妙 法 - The unexcelled, most profound, and exquisitely wondrous Dharma Q) If a proper ritual being done as per link here , then Dharma is being shared to 10 highly influential people then it multiples to 10k people in a few years time then a hell is possibly being broke theoretically ? I plan to request a monk to have some basic Buddhism sharing as many free thinkers and wrong livelihood/confuse of Buddhists here. But one suffering still applicable afterlife until enough merits accumulated from the funeral itself? Well, heavy crime punishment cant be avoided I believe. Guess, this would something like a appeal and reduce no of years like in the prisons. Iti 100-112 > "There are these two kinds of gifts: a gift of material things & a > gift of the Dhamma.
