Mo Ziran didn't know what the black mist was, it was because her previous memories hadn't fully recovered, so she didn't know many things.

Although Mu Yunjin knew, he didn't have time to tell Mo Ziran.

This is a question about the interface, as well as the exercises practiced by the Ghost Gu and the spells used by the Ghost Gu.

Now the interface where Mo Ziran and Mu Yunjin are located is called the Nether, and in addition to the interface of the Nether, there is also an interface called the Upper.

There is a big difference between the upper and lower realms, and between the two interfaces.

The entire Nether Realm is called the Purple Cloud Continent, and the Purple Cloud Continent is divided into two continents, the north and south of the Purple Cloud.

Mo Ziran's current Martial Saint cultivation, in the Purple Yunnan Continent, she can be regarded as reaching the highest level of cultivation. The Martial Saint is very powerful, even if she doesn't have Mu Yunjin by her side, even if she walks around the Purple Yunnan Continent by herself, there will be no problem, with the cultivation of the Martial Saint, she is the strong person here, whoever dares to provoke her, it must be the person who provoked her who is unlucky.

However, Mo Ziran's martial saint cultivation, if she reaches the Ziyun North Continent, she will no longer be a strong person, and when she gets there, there are still many monks who are higher than her.

However, although there are many monks on the Ziyun North Continent who are higher than Mo Ziran's cultivation, if the monks over there are compared with the monks in the upper realm, it is too far behind, the monks over there are not really strong, and the strong people who are stronger than the monks over there are actually in the upper realm.

To be precise, the gap in cultivation level between the monks of the upper realm and the monks of the lower realm is particularly large.

If a monk from the lower realm wants to go to the upper realm, he needs to go through cultivation, reach a certain level, and then survive the thunder tribulation and fly to the upper realm.

The cultivation that was originally very powerful in the lower realm, after flying to the upper realm, had to start from the lowest level of monks, which was the difference in strength between the monks of the lower realm and the monks of the upper realm.

If a random God Emperor level monk came from the upper realm, the entire Purple Cloud Continent in the lower realm would be destroyed, but Mu Yunjin's current cultivation was much higher than that of the God Emperor, and he was very powerful in the upper realm.

Because the gap is too big, what should I do in order to maintain the balance of the interface? This requires the laws of heaven and earth to control, if there is no control by the laws of heaven and earth, then the monks of the upper realm can use their powerful cultivation to come to the lower realm at will to bring great trouble to the human beings in the lower realm, therefore, the law of heaven and earth has a rule, as long as the monks who come to the lower realm from the interface of the upper realm, no matter how strong their cultivation is, they must suppress their cultivation and control their cultivation within the scope stipulated by the laws of heaven and earth.

Cultivation is suppressed, which means that Muyun Jin can't use his true strength in the nether realm, and he can't violate the rules of the laws of heaven and earth, if he uses his own cultivation, he will not only be severely punished by the laws of heaven and earth, but his strength is too strong, if he really uses his true strength, then this Purple Cloud Continent will be destroyed.

Mu Yunjin, Ye Xi, Jue Chen, they are in the lower realm, and their real power has been limited, and the ghost Gu was originally a monk in the upper realm, and in the lower realm, the power of the ghost gu has also been limited.

Not only was the power of the Ghost Gu limited, but also, according to his own guess, Mu Yunjin felt that the current Ghost Gu's cultivation had not fully recovered.

Mu Yunjin is now, in the Nether Realm, because his cultivation is restricted, he can't use his true strength, he can't defeat Ghost Gu immediately, but he also guesses that Ghost Gu can't use more powerful strength than him to defeat himself.
