Although the Eight Precepts of the Pig are noble as the Marshal of the Canopy, their mana is very mediocre, and if they were not, they would not have killed only a few monsters such as leopard spirits on the way to the scriptures.
Some people believe that the low record of the demon on the way to the Eight Precepts of the Pig is not weak, but that it is stealing and slipping, and it has not gone all out.
At first glance, this view is very reasonable, with the weak will of the Pig Eight Precepts to learn the scriptures, it is absolutely possible to steal and slip, but in fact, it does not conform to the original work. There is a plot in the original work that proves that although the Eight Precepts of the Pig are weak in will, they are also very concerned about the achievements of the demon.
In the original Red Child, Sun Wukong's mana was far above that of the Red Child, and he also had the absolute upper hand at the beginning of the battle, so why was he defeated by the Red Child in the end?
Being attacked by samadhi true fire is actually only a secondary reason, and the primary reason is precisely because of the Eight Precepts of the Pig.

The forty-first time in the original book, it is written that the Eight Precepts of the Pig are next to it, and it can be seen clearly: although the goblin is not defeated, it is only to cover the barrier, and it has no ability to attack and kill. The Eight Precepts secretly thought: No, the walker slipped away, threw a flaw in a moment, coaxed the demon to come in, and knocked down with an iron rod, and I lost my credit.
So the eight precepts of the pig were built with a rake, but I did not expect to help the red child. The red child is far from being an enemy even Sun Wukong, how can he be an enemy of the two brothers? Quickly defeated, he withdrew to Dongfu and prepared for the Samadhi True Fire Attack. Sun Wukong carelessly attacked the enemy, and as a result, he was choked by the smoke of the Samadhi True Fire, turning victory into defeat.
If the Eight Precepts of the Pig had not fought for merit, everything might have been as he expected, and Sun Wukong would have sold a flaw, coaxed the red child to come in, and knocked him down with a stick, which would not have given him the opportunity to retreat.
Pig Eight Commandments obviously cared a lot about the demon's record, but he still only killed a few demons, which was more enough to show that his mana was mediocre.
So, how mediocre is the mana of the Eight Precepts of the Pig?
Less than one-twentieth of Sun Wukong,that is to say, the twenty pig eight precepts joined forces, and they were not Sun Wukong's opponents.
This is not the author's words, and relevant evidence can also be found in the original work.
The original Yellow Robe Monster that time, the Pig Eight Commandments vs. the Yellow Robe Monster, the two sides killed each other. But this is not the strength of the Eight Precepts of the Pig that is comparable to that of the Yellow Robe Monster, the author explains, "If we talk about gambling means, Mo said that two monks, that is, twenty, can not defeat the goblin." Only for tang monks to die, there is the protector god who protects him."
However, the yellow-robed monster who could defeat twenty pig eight precepts was defeated by Sun Wukong in fifty rounds, and sun wukong's strength was more than twenty times that of the eight precepts of pigs?
We know that the Tianting Group is dominated by strength, and the higher the status of the immortals, the stronger the strength, so why is the strength of the Eight Commandments of the Pig, who is the marshal of the canopy, so why is the strength so mediocre?
The reason is actually very simple, from what Tang Monk said in the Wuji Kingdom, we can see the hint.
The king of Wuji Kingdom was killed by the Green Lion Spirit, and Sun Wukong decided to revive him with the Soul Dan. However, after feeding the Soul Dan down, it is still necessary to temper the qi in order to truly save the king.
The Eight Precepts of the Pig took the initiative to ask for help, but did not expect to be stopped by the Tang monks, the reason is: "The Eight Precepts since the child was injured and born to eat people, it is a mouthful of turbid breath; Goku has practiced since childhood, biting pines and chewing cypresses, eating peach fruits for a living, it is a breath of pure breath." Only Qing Qi can live the king of the Black Chicken Kingdom. ”
It can be seen from this that after the Eight Precepts of the Pig were degraded, they gave up on themselves and ate people for a living. This obviously seriously affected his cultivation behavior, causing his mana to be greatly reduced.
Why does eating people reduce the mana of the Eight Precepts of pigs?
Because the Eight Precepts of the Pig were originally Taoist gods, the cultivation was Daoist magic, and the first priority of Daoist cultivation was to maintain a fresh and pure essence and abandon crooked and evil thoughts. At this point, when Bodhi Grandmaster taught Sun Wukong the spell, he also specifically reminded him, so Sun Wukong "chewed pine and chewed cypress, and ate peach fruits for a living."
The Eight Precepts of the Pig eat people, defiling the fresh and pure essence of the body, and naturally destroying the Daoist practice that has been practiced for many years in the Qing Dynasty, of course, the mana will be greatly reduced.
