The stone door opened, and the golden light in the tower penetrated through the crack in the door, completely enveloping Mo Xuan's body, warm and soft.

Sensing his physical state, Mo Xuan found that he was not harmed, and he also secretly wiped the cold sweat on his forehead. Slowly exhaled two breaths, tidied up his clothes, and then Mo Xuan stepped into the tower. And as he entered, the tower door, which had just been opened not long ago, also closed again with a heavy collision sound.

Inside the tower, a piece of gold is bright, although there are no lights and candles, but it shines like a scorching sun.

Standing at the gate of the tower, I glanced inside the tower and saw that this yellow-level tower had many floors.

In the first layer, there is a spacious walkway in the center, and on both sides of the walkway, there are evenly set up a stone round platform of a hundred zhang height, and the round platform is surrounded by a layer of faint white light, which seems to be a small sealing array. At this time, there were already dozens of people cultivating cross-legged on these hundred stone platforms, and these young girls closed their eyes and sank their minds, holding all kinds of seals in their hands, all trying to absorb the source qi in the tower.

Looking at those people, Mo Xuan was also curious about the operation of the origin qi, sure enough, the concentration of the source qi here was indeed much higher, inhaling the source qi into the body and storing it in the seventh vein, Mo Xuan could clearly perceive the increase in strength, and at the same time felt the body's desire for power.

"The purity of the source qi here is extremely high, not like all the source gas stones. Absorbing a trace of source qi into his body, Mo Xuan sensitively distinguished, but he did not perceive a trace of the taste of source qi stone.

"Such a pure source qi, and the concentration is also extremely high, if I stay here to cultivate, it must not take long, my seventh vein should be full. ”

Mo Xuan smiled knowingly, walked lightly on the avenue, and then found a place to cultivate the round platform, climbed up, and cultivated cross-legged.

Closing his eyes and concentrating, Mo Xuan activated the source qi in his body, and at the same time absorbed the source qi in the tower into his body, and after running together with the original source qi in the veins for two weeks, he directly poured into the seventh vein.

After the absorbed source qi was poured into the seventh vein, Mo Xuan suddenly felt saturated, which made him very happy, and the seventh vein, which had been working hard for half a year, was finally about to be full, so he accelerated the speed of absorption.

But when he thought about it, he hadn't yet practiced the source qi operation method of the eighth vein, and it was not suitable to open the eighth vein for the time being, so he slowed down the source qi absorption and prepared to block it.

However, just as Mo Xuan was about to block the absorption of source qi, he suddenly noticed a trace of abnormality, because when controlling the source qi, he felt a trace of resistance from the source qi in his body.

"This feeling doesn't seem right. Mo Xuan was stunned, this was the first time that the source qi in his body had resisted his control since he began to cultivate.

With his eyes closed and contemplating, Mo Xuan used the seven veins of source qi to carefully examine his body. Under his careful perception, Mo Xuan suddenly found that at this time, his body had begun to take the initiative to absorb the source qi of the outside world, and the key was that he didn't know this kind of thing.

"Damn, what's going on. Mo Xuan was very alarmed, his body would take the initiative to absorb the external source qi, if this was absorbing filthy qi, then what should it be.

Mo Xuan hurriedly mobilized the source qi of his whole body, forcibly suppressed the body's absorption of the external source qi, and at the same time forcibly drove the source qi that he had previously absorbed out of his body.

Suppressing the uncontrolled source qi, Mo Xuan secretly raised his vigilance, controlling the source qi to protect his body and prevent the source qi in the tower from being forcibly absorbed into his body again.

"Fortunately, Uncle Ghost's Shen Armor allows me to cultivate, otherwise with my previous source qi control power, I may not be able to suppress this chaotic source qi. Mo Xuan sighed secretly, and couldn't help but thank the ghost shadow in his heart.

"But what happened to the source qi just now, how could it be uncontrollable and automatically absorb the source qi into the body?!" Mo Xuan frowned suspiciously, raised his head, and looked at the space inside the tower, but he didn't find anything unusual.

Looking at the surrounding teenagers and girls who were in a state of cultivation, looking at the happy smiles on their faces, Mo Xuan secretly thought: "Looking at their expressions, presumably they should have experienced the benefits here, so it seems that they are indeed absorbing source qi now, and their strength is also increasing, which means that there is nothing abnormal about the source qi they absorb." ”

"But what was the situation just now? Was it just my delusion? Or was my vigilance too high?" Mo Xuan thought about it repeatedly, and after hesitating for a moment, he said secretly: "Try again, I want to see what is wrong with this." ”

After thinking about it in his heart, Mo Xuan once again activated the source qi in his body, and at the same time began to take the initiative to absorb it, but for the sake of safety, he controlled the absorption speed to the minimum, and controlled the source qi to protect his body from harm at all times.

The source qi slowly rotated in the body, and the source qi from the outside world melted into the source qi army bit by bit after being filtered and absorbed by the veins, all of which went extremely smoothly and did not make Mo Xuan feel a trace of discomfort.

The source qi that was inhaled into the body and ran in the body for several more turns, but there was still no strange feeling, Mo Xuan couldn't help but have some doubts: "Is it really because I'm too sensitive to detect a mistake?"

The source qi ran in the body for two more turns, and there was still no strange feeling, Mo Xuan's heart secretly relaxed, and at the same time, as he usually cultivated, he directly poured the running source qi into the seventh vein.

Airplanes!

And when the source qi had just been poured into the seventh vein, the source qi in the body trembled violently, as if it was boiling, and then it was out of his control again, and it ran wildly, automatically absorbing the source qi from the outside world.

The strangeness of the source qi instantly attracted Mo Xuan's attention, and he used all his strength to control the source qi that had already been stationed on the side, first forcibly suppressing those riotous source qi, and at the same time directly squeezing out the source qi that was absorbed into his body at a lightning speed.

This series of actions was completed in one go, and after expelling those strange source qi from his body, Mo Xuan felt that his body was also much more comfortable, and after improving the source qi protection in his body again, he secretly breathed a sigh of relief.

"There's really something wrong with the source qi here. Mo Xuan sighed secretly, stood up, carefully looked at the round stone platform under him, and then reached out and touched it.

"Huh?!" Touching the stone surface with his fingers, Mo Xuan noticed something strange, as he found that the flow of source qi in his palm seemed to have suddenly intensified a little in the previous moment.

Controlling the source qi at the fingertips, Mo Xuan stroked the stone surface again, and sure enough, as soon as his fingers touched the stone surface, the source qi on the fingertips began to be slowly absorbed by the stone surface, but the speed of this absorption was very slow, if there was no relatively high control force for the source qi, it would not be possible to detect it at all.

"Sure enough, there is a problem!" This time he finally determined the anomaly here, got up and stood on the stone platform, looked around, and saw that those teenagers and girls didn't seem to have noticed this anomaly, and Mo Xuan planned to inform them.

But after thinking about it for a while, Mo Xuan still decided not to say it for the time being, as soon as he found something unusual, he didn't know what the problem was, and even if he said it, no one would believe it. Second, this is the realm of the Barren Academy, since there is something unusual here, then it must be done by someone in the academy, with his current ability of the seven veins, he is not qualified to evaluate what the academy has done, so it is better not to show it for the time being, so as not to lose his life.

"Uncle Ghost is really right, this outside world is indeed full of dangers. Mo Xuan sighed, looked up at the stone top overflowing with golden light, hesitated for a moment, and thought: "Since there is something unusual on this layer, then the second layer should be different, maybe there will be some clues to be found on it." ”

Jumping down from the stone platform, Mo Xuan reached out to help the ground the moment he landed. At this moment, he quickly controlled the source gas to test the ground, but he found that after the source gas was contacted, the ground would not absorb the source gas, so it seemed that only the strange stone platform could absorb the source gas.

Standing up, Mo Xuan pretended to straighten his collar, and then swaggered to the stairs and walked towards the second floor.

The second floor of the Yellow Grade Tower, the architectural style is almost the same as the first floor, the only difference is that there are a lot more stone round platforms for cultivation, the stone platforms are arranged in an orderly manner, at a glance, there are fifteen vertical and twenty horizontal, at least three hundred round platforms.

Standing at the entrance, Mo Xuan pretended to clean up the dust on his shoes, and quickly controlled the source gas to inspect the stone surface on the second floor, once the source qi came into contact, it began to be slowly swallowed by the ground, but the speed of this devouring was much slower than that of the round platform on the first floor.

"I didn't expect the ground here to be abnormal. Mo Xuan was frightened, and after retracting the source qi, he controlled the source qi with all his heart and firmly protected his body.

"Hey, you kid, what are you doing here?" was thinking about it, when a young man's voice suddenly came from the hut on the side.

Mo Xuan was startled, turned his head to look, and saw a man in a green robe about thirty years old walking out of the hut, this man had long blue hair, a three-foot long sword tied to his waist, the sword body was painted with a beast, and the hilt of the sword was a skeleton.

Seeing this man come out, Mo Xuan paused for a moment, his thoughts were spinning rapidly, and he immediately smiled with a slightly embarrassed smile: "This teacher, I'm really sorry, I'm a student who just entered the hospital today, and I'm not very familiar with this place, I heard them say that the Yellow Level Pagoda is a good place, so I just took a look here, if there is anything that disturbs the teacher, please forgive me." ”

"Oh, it's a freshman, it's okay, it's okay. Hearing what Mo Xuan said, the young man waved his hand and said with a smile: "Little friend, the Source Qi Tower is indeed a good place to cultivate, and you can increase your cultivation speed by cultivating here." However, due to your new life, you can only cultivate on the first layer at present, and as for this second layer, you have to go to the Medicine Pavilion to buy the 'Pure Heart Pill' before you can enter. ”

"Do you have to buy 'Qingxin Pills' to enter? Teacher, what are you talking about 'Qingxin Pills'? The students just didn't understand, so they asked the teacher to teach me. Mo Xuan clenched his fists respectfully, and he vaguely felt that this so-called "Qingxin Pill" was not an ordinary thing.

The young man was also very enthusiastic, and said with a smile: "The Qingxin Pill is a kind of pill that can refresh your whole body, because the source qi in this source qi tower is very strong, if you cultivate here for a long time, I am afraid that you will lose your mind, it is very terrifying." And this Pure Heart Pill happens to keep you full of spirit at all times, even if you keep cultivating in the tower, you won't lose yourself. However, the medicinal effect of the Qingxin Pill is only twelve hours, which means that taking one pill can only be cultivated for one day, and this must be paid attention to at all times. ”

The young man patiently explained, and Mo Xuan also listened very carefully in his heart. "Teacher, is the kind of 'Qingxin Pill' you said expensive, I just entered the hospital, and I haven't earned a waste of coins yet, so I'm afraid I won't be able to buy it for the time being. ”

"The Qingxin Pill is not expensive, only one of ten desolate coins. With your ability, you can do a random task, and it should be easy to get it. The man laughed.

Mo Xuan nodded suddenly, immediately looked at the interior of the second floor, smiled, and said, "Teacher, you see that I am also here, can I go inside to take a look, don't worry, I don't know how to cultivate, I am just curious to take a look." ”

The man shook his head and said, "No, if you want to enter the second floor, you have to take pills, this is the rule of the academy, and it is also for your safety, so I can't help it." ”

Seeing that the man refused so categorically, Mo Xuan didn't say anything more, and after bowing down to thank the man, he walked directly down the stairs, walked out of the first floor, and left this strange source gas tower.

"I've got to figure out what's in there. Looking at the yellow-level pagoda that shimmered with golden light behind him, Mo Xuan's eyes were firm. Degree of literature
