Shen Cheng is sitting on the stone bed at the moment, quietly closing and meditating, consolidating the realm that has just advanced to the fourth layer of the Qi Melting Period, the master has been away from the mountain for more than half a month, it seems that this trip is not very smooth!

Since sending Ling Xiang away that day, Shen Cheng walked into the stone room and never came out again. Regardless of whether there is a danger of going mad, it is time to break through the bottleneck, and it is time to give it a go!

After nearly half a month of adequate preparation, pranayama meditation and luck skills were completed in one go!

Although there was a slight misfortune in the middle, the lack of spiritual power in the body almost led to a failure!

But at the critical moment, it was the two low-level spirit stones left by the little old man that played a key role, allowing Shen Cheng to pass the most dangerous stage of spiritual power on the verge of exhaustion, barely supported it, and finally entered the fourth layer of the qi melting stage as he wished.

Of course, Ling Xiang's advanced experience is also indispensable!

After a day and two nights of meditation and recovery, the current fourth layer of power has finally stabilized.

Although Shen Cheng couldn't see the slightest ripple on his face, his heart was actually pounding excitedly, but he still forcibly suppressed this excited mood, took the pill and continued to breathe in and absorb the aura of heaven and earth, not daring to have the slightest slack and luck.

After another meal, Shen Cheng slowly opened his eyes, and a faint smile appeared on the corner of his mouth. At this moment, he felt that his body had been filled with spiritual power, but this spiritual power could be sent and received freely as he wished.

Shen Cheng let go of the spirit stone that he had been holding in his hand and was almost scrapped, and picked up the book of "Control Mind Decision" that he regarded as a treasure from the side. Open the last few pages and look at several auxiliary exercises corresponding to this fourth layer.

Among the several exercises that can be practiced in the fourth layer, there are two auxiliary spells that attract Shen Cheng the most, namely "Healing Technique" and "Afterimage Technique"!

After studying it carefully, Shen Cheng felt that these two spells were particularly practical auxiliary exercises.

Among them, the healing technique, which can be seen in the literal sense, is a kind of exercise that can not only treat external and internal injuries, but also have a simple detoxification effect. It can be used to heal the monks themselves, or to heal the injuries of other wounded. The disadvantage is that the healing speed is not fast, only faster than the usual drug treatment, and can only remove the general toxins that enter the body, such as ordinary snake venom, insect venom and grass venom, etc. For some special poisons in the immortal cultivation world, such as some ancient strange poisons and zombie poisons and other high-level poisons, they have no effect!

The other remnant spell is a low-level auxiliary spell, which allows the monk to move quickly and quickly over a short distance, forming a "teleportation" effect, but the speed is much worse than teleportation. And when this spell is cast, there will be a few faint afterimages left behind the caster! Casting this spell in the process of the monk's fighting method against the enemy can have a great chance to dodge the enemy's attack, but the flaw is that casting this spell requires an explosion of spiritual power to achieve the purpose of rapid movement, so it consumes more mana, and it cannot be cast continuously when the mana is insufficient!

Although these two exercises are not particularly perfect, the benefits brought by the actual effect can completely ignore the defects! After all, this is only a low-level auxiliary spell, at least for Shen Cheng, who is only in the Qi Melting Stage now, cultivating these two spells is still quite valuable!

After a while, Shen Cheng put down the "Control Decision" in his hand. He was going to take a brief rest before cultivating the above two spells.

He had been stuffy in the stone chamber for more than half a month, and it was time to move his muscles and bones! Thinking of this, he took out an aiki pill from his bosom and put it into his mouth.

In fact, when it comes to pills, according to the master, this cultivation of immortals is mainly based on "cultivation", and "refining" pills and taking medicine as an auxiliary, but who makes us have poor qualifications! If we don't take some pills to help improve our cultivation, what kind of immortals will we cultivate in this life? Sooner or later, it will turn into a cup of loess, since the Immortal Monarch Dao Ancestor of the Upper Realm also wants to take the pill, then what reason does Shen Cheng have for rejecting this pill, of course, if it is beneficial, take it!

Stretching his waist and jumping off the stone bed, Shen Cheng came to the door and pushed open the stone door.

Suddenly, a cold and cold air rushed in. This cold aura actually made Shen Cheng, who was full of spiritual power at this time, couldn't help but shiver!

He had lived in the cave for three years, but he had never felt so eerie and strange in the cave! This kind of cold was not the simple cold in winter, but a very terrible feeling.

The light stone on the roof of the stone hall still shone brightly, but it was no longer a soft milky white. Those light stones seemed to have turned a faint pale green, making the entire stone hall feel an indescribable sense of danger and creeping!

Although the cold in the stone hall was pressing, beads of sweat unconsciously oozed from Shen Cheng's forehead. His first reaction at this moment was to subconsciously pull out the Golden Snake Sword from his waist, and then turned on the Spirit Eye Technique, then took a deep breath and calmed down, and walked out of his stone room with gentle steps.

Shen Cheng cautiously walked into the stone hall and looked around with his spiritual eye technique, he felt that this must be a yin qi. Except for the pale green yin qi slowly oozing out of the stone hall wall, there was nothing special in the stone pavilion.

And the place where the yin qi seeped out the most was actually the stone room where the little old man meditated and practiced.

Shen Cheng beat the drum in his heart, he knew very well that although he was now a fourth-level monk of the Melting Qi and had learned several more practical auxiliary spells, he basically had no means to deal with the enemy, and he didn't have any fighting experience, even if he encountered a second- or third-layer opponent with a little fighting experience, he might not be able to defeat it!

But looking at the current situation in this cave, he didn't think that ordinary junior monks could make a movement.

At this time, he has completely lost the joy of just advancing!

As soon as Shen Cheng mobilized the spiritual power in his body, the Golden Snake Sword actually rose from his hand and hovered in the air diagonally above his head, the tip of the sword pointing motionless in the direction of the stone chamber where the yin qi was the thickest.

Sure enough, after advancing to the fourth layer, the spiritual power in Shen Cheng's body had more than tripled, and now he released his spiritual power to control this Golden Snake Sword, and he felt effortless. At this moment, as long as his mind moved, the Golden Snake Sword would stab in any direction without hesitation under the control of spiritual power.

Shen Cheng glanced at the Golden Snake Sword, calmed down slightly, raised his feet and slowly walked towards the master's stone room, and walked cautiously.

When he came to the door of the stone room, he listened to the movement inside, and did not feel anything unusual in the stone room, so he plucked up his heart and courage, and pushed the stone door open.

In an instant, the strange scene in the stone room had already stunned Shen Cheng and retreated again and again!
