Evil spirits are from inherently evil beasts, which are naturally more powerful and live through killing, torturing and consuming others. Examples are the "Brain Eater", "Evil Phoenix", "Man Faced Spider", skeletons, wraiths, zombies, anything that manipulates another like a puppet - generally anything out of horror fiction will be an evil spirit.
Dark spirits are not quite evil, they may not have the tendencies to murder, torture and consume, but they are close, and often confused for evil spirits. Examples are "Dark Crow", "Dark Blue Silver Grass", "Dark Phoenix", "Dark Dragon". Dark is really just an element, rather than a disposition. They may have some abilities that you wouldn't expect from a normal spirit, and that often gets them confused for evil spirits.
Because a lot of dark spirits are confused with evil spirits, they are generally shunned from society just the same
Evil spirits and dark spirits both have the tendency to grow ridiculously fast early and be more powerful than equal leveled normal spirits, though they slow down a lot from 80th rank onwards. A lot of their growth is stimulated through inducing suffering, killing or enslaving others, and as they reach higher levels they need stronger enemies to grow, resulting in a massive slowdown. While dark spirits grow from defeating enemies, evil spirits need more suffering during the process.
Typically though, an evil spirit will corrupt the user.
Ma Hongjun had an evil martial spirit, Evil Fire Phoenix. His martial spirit made him couldn't control his fire, so he need to eat a lot. His descendant, Ma Xiaotao was evil spirit master. She couldn't control her power. She had lost control of the evil phoenix power already, and she let it run rampant. As a result, her personality switched, though it was later recovered and purified by Yuhao.
"Is there any Holy Spirit now?"
"Forget it, I will inspect this matter soon"
In this world called Douluo Dalu, this continent held two great empires, which could perhaps also be spoken of as coalitions. Because within the two empires, a great deal of territory was conferred on feudal vassals, and the number of nobles with armed forces couldn't be counted.
Of these two empires, the one Tang San was in was Heaven Dou Empire, the other was the southern Star Luo Empire.
Fasinuo province was located near the border between both countries, and Holy Spirit village by Nuoding city was no more than one hundred kilometers away
"I will visit Holy Spirit Village soon"
"Let's go to the academy now"
In Star Luo Empire and the Star Luo Imperial Academy is the single largest Advanced Spirit Master Academy. Every kind of facility is perfect beyond imagination.
Only it's a pity, although Star Luo Imperial Academy is good in itself, their connection to the imperial family brings major restrictions. The Star Luo Imperial Academy's first requirement for accepting students is that the student has to be a noble, making a lot of remarkable commoner students unable to join. Also precisely because the students are nobles leads to the facilities being faultless and the teacher's strength formidable and thus the Star Luo Imperial Academy is always the first ranked, but not a lot of famous Spirit Masters appear from there."
Star Luo Imperial Academy being placed outside the capital city is out of fear the capital's lavishness will affect the student's cultivation, and even more importantly perhaps because there isn't any sufficiently large space for an academy in Star Luo Empire.
From what he knew, even though Star Luo Imperial Academy isn't considered as having a lot of students, having every kind of flawless facility requires a great deal of space. He met the guard of Star Luo Imperial Academy in the city wall. This guard acted as his guide. The teacher was respected here and had an important place in the city.
"I would be a new teacher in this academy. I'm new here. Bring me there" Then he took his registration card and the recommendation letter from Spirit Hall.
"Please follow me, grand master"
They went to the mountain. Then He finally arrived at his destination: Star Luo Imperial Academy.
"This mountain all belongs to Star Luo Imperial Academy. Eh, and that forest behind it and that lake at the foot of the mountain too, they're all under the Academy's supervision. We'll enter the Academy grounds at once."
Seeing the dumbstruck Ryu, the Guide contentedly said:
"Mountains on one side and water on the other, it really is a good place."
Ryu nodded in admiration.
The scenery here was indeed beautiful, especially this moment as the sun was setting in the west. Under the contrast of the red colored clouds in the west, whether it was the lake at the foot or that thousand-meter tall mountain covered in every kind of plant itself, all gave people a feeling like the garden of peaches of immortality."
The distance from here to Star Luo Empire's imperial capital City was less than twenty kilometers, and with such beautiful surroundings, recalling that they would live here from here on, even Zhao Wuji and the other teachers all felt greatly satisfied.
