The lowest which is also the beginning is called-

Beginner realm.

It has the initial stage ( level 1), middle stage (level 2), and the final stage or bottleneck (level 3).

This stage for an average cultivator takes at least 7 years. One starts to cultivate at the age of eight. Geniuses however who have the heavens mark between their foreheads are allowed to start as early as age 4 or 5. For them, it takes just 3 to 4 years to leave beginner realm to the next stage which is

Foundation builder having 7 levels, unlike beginner realm.in this stage, it's very hard to progress in between levels.

For trash grade roots cultivators it could mean being stuck at the bottleneck their entire life.

Average roots can break the bottleneck at 35,45, or fifty.

The geniuses, however, finish that stage at 25 and progress to the next level

Golden core stage

This stage has only two levels which for the geniuses take 5 years. an average cultivator spends 10 to 15 years on this stage.

Disciple chain

This stage has 6 levels. the first 4 are quite easy but the other two are very hard.

Only the strongest can break free to the

Master stage

This stage has 4 stages and takes 10 years for geniuses.

The saint stage has only two levels

Master saint has 3 levels

Emperor stage has 5 levels

The arch emperor has 8 levels.

Then we have-

Half eternal or half immortal which has 9 levels

Immortal stage which has 13 levels and finally

God stage which has just one level. Such existence can destroy an entire continent with just his thoughts, has the strongest beast pet and chooses to stay away from national affairs and resides peacefully in the skies. If an immortal descends for any reason, the cultivators will lose 12 years of cultivation so unless it's very necessary they cannot descend.

Long Ren is currently an emperor stage realm and is said to be the 8th most powerful beast in the forbidden mountain. He used to be very arrogant having killed a total of 50,000 cultivators who tried to tame him both male and female, young and old, cute and ugly.

It is understandable then, why he resents being a pet to Theresa who did not even make an effort to ask for a contract.

The dragon bone whip's spirit guardian Ju Wei is in saint level so you can say the whip can kill saint level and below. You can also say those who came to ask for contracts from different nations were all saint or below saint level. He viewed them as very unworthy to be his master especially since he didn't want to be ever bound by a contract. Theresa's ability to control Ren with her mind is a cheat and the only cheat in cultivation. I will not make her rise to half immortal overnight because I doubt she'll even appreciate it. That's why I gave her a phone. I hope you guys will stick to Theresa as she proceeds to take revenge on Han Fei's enemies and finally conquering the emperor's heart.
