What method is used to find the fastest speed of Huang Xian?

Hehe, it's not a matter of speed, but whether this person's physique is more suitable for communicating with Huang Xian, so as to know the speed of inviting Huang Xian's upper body. However, Huang Xian, Fox Fairy, Bao Jiaxian and Ma Xian are all among the six sentient beings, which is problematic. As I explained before, I posted them below for your reference:

These invited immortals are real or fake. But the so-called "immortals" invited by these methods are all one of the six sentient beings. I will tell you the principle carefully:

Our world is called the world of women, and the so-called "woman" means "tolerable", which means "tolerable". In the words of Buddhism, we have had a hard time, but our spiritual wisdom is still there, which is much more bitter than the hungry ghost in hell. We also have happiness, but it is much worse than the happiness in the fairyland (heaven) and Asura Road, which we don't know and don't want to practice, so this environment is the most suitable for practice, so it is the best carrier for a person. The so-called "no desire, no desire, no reincarnation, no love and no wife" is such a situation.

These spirits, such as Tangkouxian and Baojiaxian, came from six places. Some of them fell from Heaven and Ashura Road, and they were pure spirits. Some of them escaped from hell and hungry ghosts, and they were also pure spirits. There are also animals (such as white snakes) from the side door or plants (such as ginseng baby and gourd baby) that accept the beauty of heaven and earth and the essence of the sun and the moon. Their bodies will be destroyed, such as lightning robbery, natural disaster, and so on. So no matter where they come from, they have no bodies, so their practice can't achieve the maximum benefit, so they should find bodies to practice for them, or use small magical powers to attract incense. As for those spiritual bodies looking for new bodies, those with high skills directly destroy people's souls, forcibly live in them (this is called "possession", a special term), and those with low skills possess themselves, gain positive energy through doing good deeds, and win people's worship; Or do bad things and get life energy through improper means, so the situation you mentioned above appeared. They can't be called "immortals", they can only be regarded as evil spirits (things that do bad things) or righteous spirits (things that do good things). Therefore, the so-called "asking God is easier than sending God" is suggested to be ignored. Buddhism is orthodoxy, which is either evil or deviant.
