The temperature here is on the high side, which makes people feel a little bored, but fortunately, there is plenty of oxygen, and it feels much better when you settle down. The aura in this confined space is even more intense, perhaps a thousand times that of the outside world. There was no need to draw qi into the body at all, the aura of heaven and earth drilled into the body everywhere, and Yu Lang had to use a grinding stone knife to frantically consume internal breath to barely maintain balance. In other words, if it were an ordinary person who didn't know how to cultivate, it would be difficult to escape the tragic end of dying by exploding when he came here.

After relieving for a while, Yu Lang regained some energy and got up to look around.

This seems to have been carved out of the main hall of the palace, which is supported by eight stone pillars, which are carved with intricate textures, and look quite old.

Yu Lang's location is just a small corner, about five zhang away there is a tightly closed copper gate, the gate is carved with the same texture as the stone pillar, there is a pair of copper rings on the door, it should be used to pull the door, but the position of the copper ring is extremely high, Yu Lang does not believe that there are such tall people in this world can get that pair of copper rings.

In the center of the hall is a pool, the water in the pool is very clear and shallow, and there is a stone with a strange shape on the side of the pool, and the stone is engraved with the four ancient characters of "washing the scriptures and cutting the marrow".

Seeing this, Yu Lang had a smile on his face, it seemed that this place was indeed the place where the Moon Washing Academy was located.

Questions such as whether you will be punished for washing the meridians without the permission of the academy are no longer in the scope of Yu Lang's consideration, and there is no provision in Dabi that it is not allowed, and if you don't say it, you will acquiesce, this is Yu Lang's understanding of the rules. Looking at the rules is never just about what it says, but also about what it doesn't say, and if it doesn't prohibit it, there is no reason to punish it. This is not to blame the rule-makers of Dabi, who would have thought that there would be students who would be able to find the side entrance of the marrow washing hall? There was a town stone at the entrance, and even a cultivator at the peak of the void had no chance of breaking through the town stone.

Yu Lang approached the pool and found that the water in the pool was produced by the liquefaction of stalactites on top. No wonder Yu Lang felt that the aura here was thousands of times richer than the outside, and the liquid in the pool was the marrow washing liquid formed by liquefaction in the cold, so the Moon Washing Academy could only provide a place for new students to wash the marrow once in three years, and it would take time for the water in the pool to accumulate slowly.

Liquefy. Yu Lang thought of this, and suddenly a bold idea came to his mind, according to the physical knowledge of the previous life, water vapor liquefies when it is cold, and the lower the temperature, the higher the efficiency of water vapor liquefaction. Grinding knives are naturally cold all over! Yu Lang picked up the sharpening knife and found that many water droplets had condensed on the blade, many times faster than the stalactites on the top of the pool.

He hung his sword on the table in front of the pool, and aimed the mouth of the jade net bottle that Yang Yuhuan had given him at the tip of the knife, and the marrow washing liquid produced quickly slid down the blade to the tip of the knife drop by drop, and finally dripped into the jade net bottle.

Unexpectedly, there was a providence in the dark, and the grinding stone knife and the jade net bottle were combined by Yu Lang to obtain a large amount of marrow washing liquid.

The water in the pool did not move, it was used to soak and wash the marrow, the pool material itself is also special, and the use of this stone may be able to give full play to the maximum effect of the marrow washing solution, so Yu Lang did not act rashly to take the liquid in the pool.

Yu Lang took off his torn academy training uniform and jumped into the pool.

In an instant, it seemed that thousands of ants were biting Yu Lang's body, and he couldn't help but snort a few times in pain, surviving the pain in the early stage, followed by indescribable comfort, and the marrow washing liquid entered through every pore of his body to help him clean up the impurities in his body.

Yu Lang closed his eyes and quietly enjoyed the transformation of the body by the marrow washing liquid, and unconsciously became sleepy and unbearable, and actually fell asleep.

When I woke up, the marrow washing liquid in the pool changed from the original clear and transparent to extremely turbid, and the aftermath jumped up from the pool in fright.

The leap almost hit the decoration on the top of the main hall, and Yu Lang was startled, and forcibly twisted his body in the air to settle.

Yu Lang couldn't help but look inward, the majestic inner breath in the dantian was surging, and there was no longer any need to rely on the copycat version of the internal breath to fill the façade, Yu Lang was so excited that he almost cried, this journey was too difficult.

Due to the accumulation of thick and thin, as soon as Yu Lang Dantian Fu penetrated, the realm had already reached the middle realm of the hundred refinements, and with the blessing of the two dangers and the martial soul pool in the grinding stone knife, even the opponents of the upper sea realm could also compete.

Yu Lang pinched his nose and put on his dirty training clothes, took the jade bottle and shook it, feeling the weight of the liquid in the bottle, quite satisfied. After washing the meridian and cutting the marrow, Yu Lang's already extremely sharp five senses were even more terrifying, and almost immediately heard a slight noise outside the door, drilled back into the hole, put the original shelter at the entrance of the cave back to its original position, and ran away all the way.

——————————————————————————————————————————

Yangzhou City, in the Moon Washing Academy.

Du Fu teased Qingqing several times to no avail, so he had to sit down in the seat next to her: "Dean Chen said, Yu Lang will definitely survive this catastrophe, don't worry too much, what the dean and other characters say is always true......"

Qingqing's eyes were weak: "Did the dean still say that the mountain closure is absolutely safe, how could the Yellow River Ancestor's mount suddenly appear, it was a fierce beast comparable to a peak cultivator of the sea, and it was stopped and bitten...... Li Dahu: They said that the abdominal cavity was bitten...... Yu Lang didn't have a dantian, how could he survive......

As he spoke, he became even more sad, and his tears smashed straight on the stone table.

"The dean didn't say that it was absolutely safe - only young people like you who have not been deeply involved in the world like you like to use such absolute words, but it is relatively safe, after all, there are still uncontrollable factors, but you believe me, Yu Lang is indeed fine. I spent my life span yesterday to spy on the heavens to take a look at Yu Lang, not only did he not die, but he was going to be a blessing in disguise......"

"Don't lie to me with such words." Qingqing didn't want to believe half a word of Du Fu's words, a month ago Du Fu said that Yu Lang would come back in two days or else he would travel to the city in women's clothes, twenty days ago just after visiting the city and swore that Yu Lang would not come back within three days to kill a large vat of vinegar, ten days ago he took a head guarantee, this time what kind of night watching the sky and fortune telling, Qingqing wanted to force himself to believe, but he was so tired that he couldn't believe it anymore.

After Yu Lang's accident, the Moon Washing Academy immediately terminated the closure of the mountain, and sent many disciples to search in the mountain for ten days, but no one found where Yu Lang was.

The Yellow River Ancestor's mount was slaughtered on the spot by the enraged Du Fu, and it is said that he also invited many teachers from the academy to rub a spiritual meat soup afterwards.

Dean Chen asked the Yellow River Ancestor what compensation he wanted for the killing of his mount, and the Yellow River Ancestor promised with a sad face that he, his grandson, and the three hundred disciples would never set foot on the south bank of the Yellow River again for the rest of his life, and sent a generous gift to the Moon Washing Academy.

Dean Chen shook his head and said it wasn't enough. The ancestor of the Yellow River cut off his left arm on the spot, and abolished the dantian of his grandson Zhu Yiming, so that he was able to get out.

The generous gift of the ancestor of the Yellow River was converted into cash by the academy and distributed to all the students who participated in the big competition as condolence money, why should they condole? Because the last round of the big competition was completely canceled, many students gave up their thoughts.

"Qingqing, you will follow me in the future, Yu Lang's kid was originally a silver-like wax spear head, which is useless, and now I am afraid that he will become a lonely ghost and a wild ghost, we two are talented and beautiful, wouldn't it be right?" Qingqing, who was taking a walk in the small school yard, was harassed by this annoying fly again.

The big name of "Fly" is Cangying, who is one year older than the young man, and he is also a figure who has been in the limelight in the Fengshan Dabi, and it is said that he finally handed over twenty yuan - in fact, he picked it up when Li Dahu and others were not interested in taking care of it.

Cang Ying's strength is not weak, swimming in the sea realm, if it wasn't for the chasing wolf to stir up the situation that day, it would be possible for him to get these sources in the end. In his heart, Yu Lang has always been an injury that can't be revealed, and he can't compare to Nan Jiyun, Wu Songru and other demonic characters who break through the virtual realm, why should he be out of the limelight by Yu Lang, a waste who can't get through the dantian. Whether it is the third round of the big competition or the literary exam, Cang Ying's heart is holding a fire.

He didn't like Qingqing much when he pursued Qingqing, but he just had some obscene thoughts in his heart, wanting to completely suppress the shadow of the remaining waves under him. Originally, the best target for venting should be Yang Yuhuan, who has always looked at Yu Lang differently, but Cang Ying knew Yang Yuhuan's identity, and he didn't dare to show any courage from him.

Usually Qingqing ignored him with a cold face, and the matter passed, after all, this person's cultivation is high, and Qingqing doesn't dare to provoke him too much. But today, for some reason, Cang Ying made a mess several times, and even pulled Qingqing's sleeve.

Under the dispute, Qingqing's sleeves were torn open, revealing half of Bai Shengsheng's arms, and tears flowed out immediately.

Most of the students in Xiyue Academy are of good character, so naturally they can't see this kind of bullying of female students. Qingqing used to be arrogant and domineering, but these days she is exhausted and has become self-pitying and self-harming.

Xue Wenyang and Xie Zhiqian took the lead in standing up, leading a group of students from the Moon Washing Academy to form a human wall between Qingqing and Cangying.

Xie Zhiqian scorned Yu Lang on the day of admission, but after seeing his talents, he was convinced, he couldn't see a man bullying a woman in his life, so he took the lead in drawing his sword out of the sheath and proposing a duel to Cangying.

"Hundred Refinement Middle Realm challenges the Swimming Sea Realm, isn't this hitting a stone with an egg?" The onlookers all sweated for Xie Zhiqian.

Cang Yingke was reluctant to let go of this good opportunity to show his skills, for fear that Xie Zhiqian would regret it, and also pulled out his long sword to fight: "If you don't accept it within three moves, I will lose!" ”

Xie Zhiqian's family origins, although he cultivated as a mediocre swordsmanship, he was extremely superb, and the first move was the Xie family's world-famous "Lonely Cloud Coming Out", which was extraordinary.

Cang Yingtuo was big, and he didn't use cultivation to suppress it, but took the move head-on, but found that his comprehension of kendo was more than one step behind the other party, and he was quite embarrassed.

Seeing that it was about to be dragged to the third move, Cang Ying was unwilling to lose face, and the cultivation of the sea border climbed to the top, broke the skill with his strength, and smashed Xie Zhiqian's abdomen with the sword body. Xie Zhiqian flew out upside down, and barely managed to stabilize his body when he hit an ancient tree, but his throat was sweet, and he spit out a mouthful of blood.

Cang Ying suddenly panicked, because of Xie Zhiqian's exquisite swordsmanship, he unknowingly faced the other party as a master of the same level, and the shot was too heavy.

Nan Jiyun, who had just come out of the Wulian District Yanwu Pavilion and bumped into this scene, frowned, ready to take this head for Yu Lang and teach this annoying "Cangying" a lesson.

An unidentified object fell from the sky, smashing the hard soil of the small school yard into a depression.

In the smoke and dust in the sky, a young man holding a black short knife walked out.

Cangying took two steps back as if he had seen a ghost.

Qingqing was humiliated, Xie Zhiqian was seriously injured, and Yu Lang was furious in his heart.

Cangying felt an unprecedented crisis, and he was about to be removed from the Moon Washing Academy, so it was better to ask for a good time! With an angry shout, his whole body was clear, and the killing intent was rushed to the extreme, and he actually wanted to kill Yu Lang with a sword.

Yu Lang was extremely keen, and even dodged his body before Cangying stabbed this sword, and also slapped Cangying on the chest with the blade.

In the way of the other, give back to the other.

Cang Ying was lying on the ground, looking at the clouds in the sky, only to feel that this seemed to be a nightmare, his muscles and veins were shattered inch by inch, and from then on, he was a waste man who walked a few points slower than ordinary people.

"It's a long time! Hundred Refining Middle Realm One Knife Kills the Sea Realm ......"

Nan Jiyun withdrew the Juque Sword, shook his head and smiled: "After all, it is young and frivolous. ”

Qingqing looked at Yu Lang angrily, with a look of disregard for the rest of her life.

Yu Lang also tore off the sleeves on both sides of his clothes, revealing two solid arms and posing like a strong man, and said with a smile: "You should wear it like this in summer to be cool." ”

Qingqing couldn't hold back the smile in her eyes after all.

"Don't say more, Lao Xue, come and help see how Xie Zhiqian is doing? Didn't you study medicine? ”

No one knew that Yu Lang's seemingly dashing flying appearance was actually thrown directly from the council hall by the angry Du Fu.

I used up a pool of marrow washing solution privately, not only used it, but also packed it away?! How do you want me to help you with this thunder!
