"Yes, Master Jingci is locked in the dungeon next door!" Master Kuteng pointed to the stone wall in front of him and said loudly: "There is a stone door there, the first mechanism rotates three squares, the second mechanism rotates two squares, and the third mechanism reverses and rotates four squares, and the stone door can be opened!"

"Well, okay!" Ye Xing nodded, and immediately walked to the stone gate, turning the knob next to the stone door according to Master Withered's instructions.

"Bang!"

With the rotation of the mechanism, the gate slowly opened, and a dark and deep passage appeared in front of Ye Xing.

The silent black mist in the passage was very thick, like a fierce beast with teeth and claws, floating in a dense vein, constantly devouring all the energy in the space.

After stepping into the passage, he walked forward for a hundred meters, and suddenly his eyes widened, and Ye Xing entered the fourth blackstone dungeon.

The black stone walls, the black stone floor, the black stone roof, and the silent black fog around it form this eerie black stone dungeon.

I saw an old nun wearing a robe and a nun's hat locked up in the iron prison of the blackstone dungeon.

"Amitabha, Master Ye Xiao, you are here!" The old nun was kind and kind, twisted the Buddha beads, and said towards Ye Xing.

"Well, you should be Master Jingci!" Ye Xing looked at the old nundao. There is a calm breath around the old nun, if the withered vine master is like a dead wood that does not move, then this old nun is like a stagnant water, like a lake water, the ancient waves do not move.

"It's the poor nun!" Master Jing Ci glanced at Ye Xing, frowned slightly, and said loudly: "Has the little benefactor often used the Soul Dementor Dafa recently?"

"Uh-" Ye Xing was slightly stunned, then nodded.

"The Great Law of Dementorship is a unique mastery of the benefactor, which is extremely powerful and has the ability to be mysterious and unpredictable. However, there are two sides to everything, and if you use it too much, I am afraid that it will be counterattacked. Master Jingci twisted the Buddha beads too lightly, and gently persuaded: "Good, good, good! It is estimated that the spiritual power of the poor nun Guan Xiao Benefactor has been consumed by more than half, and the "Soul Dementor Dafa" should be used cautiously in the future!"

"What the teacher taught me is that the younger generations will pay attention to it in the future. Ye Xing nodded.

In the past month, Ye Xing has indeed used the "Soul Dementor Dafa" frequently, first using the Ecstasy technique to subdue the Xuantie Gate Lord Iron Zhan, and then fighting against the three elders of the Medicine King Valley, Xiahou Lie, and taking him as his subordinate. Coupled with the previous Moon Worship Ink Robe Lord Yan Jiu and the Medicine King Valley Shaogu Master Jiang Yuhang and others, Ye Xing's spiritual power was very consumed.

You must know that the "Soul Dementor Dafa" is not something that can be used at will, otherwise if it can be used at will, wouldn't it be invincible and infinitely subdued his subordinates. However, this is not the case, although peerless magic skills such as "Soul Dementorship Dafa" are mysterious and unpredictable, they actually have conditions for use, that is, spiritual power.

Because the ecstasy of "Dementor Dafa" is essentially the use of spiritual power to control others. If controlling a third-class innate realm consumes one point of spiritual power, controlling a second-class innate realm consumes ten points of spiritual power. Then controlling ten third-class innate realms and one second-rank innate realm is to consume twenty points of spiritual power. If the caster's mental power is less than 20, then they will be counterattacked.

Of course, it must be very easy to control the second- and third-rank innate realms, after all, Ye Xing's spiritual power has become extremely huge with the help of the Condensing Pill, and it can be said that it is stronger than the vast majority of first-rank innate realms. In terms of spiritual power, Ye Xing estimated that he was already comparable to the Supreme Overlord level.

If it were usual, this spiritual power would be absolutely sufficient. However, this month, Ye Xing first subdued the Xuantie Gate Lord Iron Battle, and then subdued Xiahou Lie, who was in the middle of the first rank of the Innate Sect. At this moment, more than half of the spiritual power was directly consumed.

In fact, Ye Xing was still very cautious in using the "Soul Dementor Dafa", but recently, in order to speed up the improvement of the strength of Baiyun City, in addition, the Xuantie Gate Lord Tie Zhan and the three elders of the Medicine King Valley, Xiahou Lie, were also very strong, and after thinking about it again, they took it as their subordinates.

"Master Ye Xiaoshi now has a lot of magical skills, and there are not many things that Poor Ni can teach you!" "Master Jingci said loudly: "In this way, Poor Ni has a unique study here, called "Ice Heart Formula", which has the effect of concentrating and calming the mind, which can significantly improve spiritual power, and should be more suitable for you." Poor nuns, this will be taught to you!"

"Thank you, Mrs. Shi!" Ye Xing said happily. Listening to Master Jingci's description, this "Ice Heart Technique" and "Soul Dementoring Dafa" seem to have complementary effects, if they can be practiced, then the problem that plagued Ye Xing will also be solved. To be honest, since he used more than half of his mental power, Ye Xing felt that there was a little more impatience and anxiety in his emotions, although it was not very obvious, but in the long run, it would definitely have some adverse effects on his cultivation. To use an analogy, once the CPU and memory of a computer are overused or not used enough, they will be stuck one by one, and various bad states will appear.

"Then you can listen well! Poor Ni will pass on your "Ice Heart Formula" mental formula!" Master Jingci paused slightly, and immediately said aloud: "If the heart is like an ice heart, the sky will not fall, and the heart is like stopping water, and all things will be revealed...... Hydro ice ...... Meaning like a knife......"

With the teaching of Master Jingci, Ye Xing gradually sank into the mental formula of "Ice Heart Formula", and a cold feeling surged in his mind for no reason, and the spiritual platform was empty, like a clear stream of ice water flowing through his heart, eliminating the restlessness in his heart invisibly.

After learning the "Ice Heart Formula" and saying goodbye to Master Jingci, Ye Xing immediately left the Black Stone Dungeon. After all, the silent black fog in the blackstone dungeon is very terrifying, and it has been continuously swallowing people's true yuan power, if one accidentally stays there for a long time, then it will be a catastrophe and will be trapped in the blackstone dungeon forever.

Therefore, every time he went to the Blackstone Dungeon, Ye Xing was in awe of caution. The mysterious blackstone dungeon was like a huge mystery that had always haunted Ye Xing's heart.

After returning to the Black Wind Ridge, Ye Xing began to cultivate the "Ice Heart Technique" and "Jiuyang Divine Skill", and his strength was also improving by leaps and bounds.

The construction of Baiyun City is also in full swing, and every day, a large section of the city wall rises on the mountain, and the strong city walls are connected and spread towards the distance.

Within the city walls, buildings began to rise from the ground, first the city lord's mansion, then houses, shops, bluestone paving, square streets.

The sun rises in the east, the sun sets in the west, day after day, time flies, and more than a month has passed in the blink of an eye.

On the Black Wind Ridge, which stretched for tens or hundreds of miles, a steel city rose from the ground and stood on the top of the mountain.
