"Of course this Soul Binding Star Array is more profound than what you have seen outside. This is an Immortal Level Formation, how can it be compared to the formation you have seen in the lower realm." The old man said.

Ye Xiao nodded his head then looked at Lin Hao and said, "Lin Hao, we have to hurry, I can not suppress the energy within me anymore!"

Lin Hao nodded his head and asked the old man, "Tell me, how to break this array?"

The old man did not reply to Lin Hao, instead, he looked at Ye Xiao and said, "Since little friend knows about this array, he should also know how to break it?"

Ye Xiao nodded his head and replied, "I do know but will that work on this Immortal Level Array?"

"Well, it will work but the strength required to break this Soul Binding Star Array is much more than what you can think of. To break this array, one must have to have the strength equal to that of an Early Immortal Foundation Realm martial artist!"

When that old man said this, Lin Hao and Ye Xiao both were shocked. Although both of them had killed an Immortal but at that time, that immortal was not at his peak state. He was weakened and the strongest power he showed was that of a Martial Saint Realm martial artist.

But even so, just to kill that giant immortal, Ye Xiao was forced to his current situation where he could not even use his own spirit energy at his will.

It was also the second time they heard about the Immortal cultivation level. The first time was when the old man mentioned him being an Immortal King. And now was the second time when the old man told them that if he wanted to destroy the Soul Binding Star Array, he needed to have the strength at least at the Early Immortal Foundation Realm.

"Senior, about the Immortal Foundation Realm... we don't know anything about the Immortal cultivation realms so can you please elaborate about it?" Lin Hao asked the old man.

"Sigh! You two should not know about the Immortals this soon but since it is related to my freedom, I will explain!" That old man said with a sigh.

"Just like mortal cultivation realms which are divided into seven levels known as Body Refining, Qi Condensation, Origin Core, Martial King, Martial Emperor, Martial Ancestor, and Martial Saint Realm, Immortal cultivation realms are divided into four levels. These four levels are known as Immortal Foundation Realm, Immortal Lord Realm, Immortal King Realm, and Immortal Emperor realm."

"The world that you belong to is one of many lower realms. Immortal can only exist in the upper realm. If any immortal were to come down at the lower realm, the lower realm will try its best to force back that immortal to the upper realm. If not, then the lower realm will be destroyed."

"Well, I was saying about the Immortal cultivation realms. The four major Immortal Realms are further divided into three minor stages known as Early, Middle, and Late."

"When One cultivated to the peak of Martial Saint Realm, they can cultivate their dantian and transform it into a world. Only after forming a world can they take a big step forward in their cultivation and become an Immortal."

"After forming a world, one can truly break through the shackles of being a mortal and become an Immortal."

While the old man explaining about the Immortal cultivation realms, Ye Xiao and Lin Hao was hearing it attentively. They did not want to miss out on a single thing as this was once in a lifetime opportunity for a person like them who belongs to a Lower Realm.

"Senior, none of us is an Immortal and we don't have the confidence to show such power. How can we break this Soul Binding Star Array?" Lin Hao asked.

"Well, we can give it a try!" Ye Xiao looked at Lin Hao and said.

"How? You can not even use your true strength right now, how can we show off the power equal to that of an Early Immortal Foundation Realm martial artist?"

Lin Hao did not believe that both of them could break the Soul Binding Star Array that was sealing this old man here for hundreds of thousands of years.

Ye Xiao shook his head and said, "Although what senior has told is true but there is another way to break this array."

"Another way?"

"Another way?"

Both Lin Hao and the old man were surprised after hearing this. Even that old man did not know any other way apart from using the strength equal to that of an Early Immortal Foundation Realm martial artist to break this array.

Ye Xiao has the memories of the Ancient Formation God and he knew every method to lay down and break these types of arrays. Although the limit of his knowledge currently was that of Lower Realms but he thought that the method to break this array should still be the same.

"Yes, there is another way. Please give me some time!" Ye Xiao nodded his head and sat down cross-legged at the same place he was standing.

According to the knowledge he gained from the Ancient Formation God, there was three-way to break the Soul Binding Array.

The first one was the same method as what the old man just said. Using the strength to forcefully break this array. The second method was to thoroughly understand the array, find the flows and break this array using those flows.

And last but not the least, the third method to break this array was to use the soul force stronger than what this array could suppress.

The Soul Binding Star Array was laid mainly to suppress and seal one's soul. There was a very high risk for using the soul force to break it but what Ye Xiao has was no ordinary soul. His soul was known as the Ancient Divine Soul.
