"Since the juniors have brought it up, they have taken risks, and they can blame themselves for their unfortunate death in the process, so the seniors can come. Li Yifeng said confidently.

"Very good! The old man likes people with courage, it takes some time to prepare the materials, and you can adjust the state to the best here by pranayama. Yu Tianshan smiled, and then left the room to prepare materials.

Since Li Yifeng had confidence, he calmed down and adjusted his state, and handed over all the loot obtained from the ruins of the bell to Xiao Meng to deal with, and at this moment, the operation of the holy cultivation technique slowly entered the state, and the exercises that had been practiced countless times in his mind were practiced again.

Three months later, Yu Tianshan returned to the inn, and his breath was as if there was nothing in his body, and he knew what was left behind in the battle with people without guessing. In order to get enough materials for physical training, Shan Lao took over a grudge with a strong man in the middle of the merger, although both sides were defeated, but the materials were obtained so that Shan Lao ignored his injury.

Li Yifeng noticed the abnormality from the moment Shan Lao returned to the room, just because his cultivation was not enough to investigate clearly, although he had doubts, but Shan Lao didn't say anything and didn't know where to start, so he thought about it so far or advanced first.

After Shan Lao returned, he waved his hand, and a wooden barrel that could hold three people appeared in the room, and as soon as the storage ring lit up, countless materials were poured out, filling the entire wooden barrel.

"Take off your clothes and meditate in the barrel, and if you can bear it, you will try your best to temper it, and if you can't bear it, you will leave the barrel. Yu Tianshan said with a serious expression.

Li Yifeng did as he was told, took off all his clothes and entered the wooden barrel to meditate, and his whole body slowly sank until it was over his neck. But the expected pain did not appear, and it was even a little cool, and when he was confused, he saw Shan Lao spit out a pale green baby fire refining the material.

"Ahh

A heartache came, Li Yifeng couldn't help but scream, beads of sweat the size of beans appeared on his forehead, his entire body seemed to have been cut by a thousand knives, and a trace of vermilion overflowed from the corners of his mouth.

"This is just the beginning, the old man only refines one-tenth of the material, if you can't bear it, you leave the barrel, if you can bear it, you will slowly adapt to this force, and when you get used to it, you will slowly refine the material. Yu Tianshan said worriedly.

Although the seniors are relieved, such pain is not enough for him to retreat, but the seniors are injured and should not use mana again. Li Yifeng said this with difficulty.

"You kid worry about yourself first, the old man's injuries can't heal in a day or two, and concentrating on refining the physical body is the key. Yu Tianshan said in surprise, the injury was still seen through by the juniors, and he was a little disgraced.

"The juniors have experienced a lot of pain like this, and the seniors still heal the wounds first, and then say, if you want to refine the materials, the juniors can do it themselves. Li Yifeng said worriedly, and then spit out a pitch-black and golden Dan fire.

"That's it, just call the old man when you need help. Yu Tianshan no longer stubbornly put away the baby fire and said, and then meditated on the bed to heal the injury.

Li Yifeng has been running the chapter of cultivating the holy technique from the very beginning, and the central method of the chapter can speed up the refining of the physical body, and he has unconsciously absorbed the essence refined by the materials, although the strength of the physical body has improved a lot, but there is still a big gap in wanting to break through the realm of breaking through the bamboo.

Immediately, the pitch-black and golden Danhuo refined the material, and the addition of the power of chaos made a qualitative leap in the material, not only pure and unadulterated, but also improved the effect of refining a lot.

Li Yifeng, who has adapted to the medicinal properties of the material, continued to refine the material, and in just three months, all the materials were refined into liquid, and the person who soaked it had already entered a state of emptiness, and everything in the outside world was completely unknown.

While refining the physical body, the operation of the cultivation of the Holy Technique was also slightly accelerated, and the breath of the whole body was all compressed in the chaotic dantian under the influence of the power of chaos. The lush trees slow down their growth and develop small buds at the ends of their branches, signaling that they are about to reach the flowering season.

Time flies, and a year is a year in the blink of an eye. It can be said that it is an alternative approach for Yu Tianshan to stimulate the cultivators of the Transformation Stage with the training materials of the Fusion Period, but only in this way can there be a chance to break through the bottleneck. Today's Li Yifeng has completely absorbed the essence of the material, and he has reached the realm of Great Perfection like a bamboo, and the next level of realm is as solid as gold at his fingertips.

The essence of the material is absorbed, the liquid becomes solid, and then changes to gray sand. Li Yifeng woke up from the empty state, and when he stretched his muscles and bones, there was a cry of "crackling", and the power of his physical body had reached a new realm.

Coming out of the wooden barrel and finding that Shan Lao was still healing, Li Yifeng, who had nothing else to do, meditated and breathed, and kept practicing the exercises of the flowering period in his mind, and this enlightenment was another few years.

In the past few years, the exercises have been practiced perfectly, just waiting for the opportunity to advance, but helpless is the lack of spiritual energy in the demon world, and if you want to advance, you really need the help of Xiao Lingtian, and at this time, Yutianshan has also completed healing.

"It's progressing well, through the first layer of physical training, you can carry out the second level of physical training, this place is no longer suitable, you have to go to that place, if you advance, it will not attract more variables to the monks. Yu Tianshan said with satisfaction.

"Yes, Senpai. The juniors are already preparing for the next round of tests, are you going to go now?" Li Yifeng said with admiration.

"It must be now, there are still ten years left before the day of the selection of the Holy Son, and it must be advanced as soon as possible so as not to be hastily selected, which also increases the chances of being selected. Yu Tianshan couldn't wait.

Then the two left the inn, and when they got out of the city gate, they went to their destination as fast as they could.

One of the ten dangerous places in the Demon Realm, the Bone Devouring Forest. Two uninvited guests came today, an old man in a gray robe and a young man in a black robe.

It is rumored that the monks who entered the Bone Devouring Forest died nine times, and in addition to being covered with poisonous mist, the entire ground was wet and corrosive, even if the grade reached the level of the Heavenly Demon Treasure, he could not stay in the Bone Devouring Forest for too long.

The two figures moved forward step by step, and with each step there was a "ticking" sound, like the sound of dripping water, more like the sound of life loss, and the treacherous bone-eating forest echoed with the wails of the undead, impacting the body and mind of the two.

"Ignore the wails of the undead, they can't hurt the monks at all, and a lack of will will give them a chance to eat away at their minds. After the first layer of training, you are immune to the slime on the ground, as long as you don't stay too long, you'll be fine. Yu Tianshan explained.

"This place is indeed a good place to practice, where is our destination?" Li Yifeng said with a sigh of all the things here.

"Since you want to train your body, you naturally choose the most dangerous place, and there is a bone-eating pool in the deepest part of the Bone Devouring Forest, which is the place of test. Yu Tianshan said with some excitement.

The two of them didn't say a word all the way, and finally came to the Bone Eater Pool after passing through countless dangers. This journey is also thanks to the coercion of the mountain old merger period to be unimpeded, and Li Yifeng alone may have been injured.

"This place is the Bone Eater Pool, why can't you see the pool, does it take a special technique to take shape?" Li Yifeng asked puzzled.

"No, the Bone Eater Pool is right in front of you, but the water of the pool is perfectly integrated with the environment. After saying this, Yu Tianshan threw out a small stone.

The small stone fell to the ground and stirred up a slight sparkle of water, and a wisp of smoke emanated from the pool water, Li Yifeng's robe was corroded in an instant, and the mountain elder had already taken precautions to avoid slipping.

"Just the water vapor is very corrosive, not to mention the pool water, do you feel the hot pain coming from your skin now?" said Yu Tianshan with a serious face.

"I didn't feel anything, I could only enter the pool and try it to know, my body was agitated, and I couldn't wait to enter the bone-eating pool. Li Yifeng said excitedly, and then jumped into the bone-devouring pool.

"Ahh

With a scream, the bones of Li Yifeng's whole body felt tingling, several times stronger than the previous training, if he had not advanced to the Great Perfection Realm, I am afraid that he would have fainted in pain.

Needless to say, Li Yifeng ran the cultivation of the Holy Technique to refine the physical body. At this time, the bone-eating pool seems to have a spiritual intelligence, and the pool water in its original liquid state attracts nearby water vapor and dense fog, and the pool water gradually becomes viscous, and its power naturally rises sharply.

Enduring the pain, Li Yifeng's will was extremely firm, and the cultivation of the Holy Technique was even more operational, and the power of his physical body was improving at a speed visible to the naked eye. The flesh also swelled and contracted due to the erosion of the pool water, the blood vessels were exposed to the skin, and the pale golden blood also turned black due to the toxin, and there was a tendency to explode and die.

Yu Tianshan on the side stared at each other, and rescued him when he had to, but as Li Yifeng absorbed the essence of the pool water, his swelling and shrinking body began to stabilize down, the exposed blood vessels also returned to their original positions, and the black blood gradually returned to pale gold.

The whole process seemed to be brief, but in fact it took a year, and Yu Tianshan was nervous all the time, afraid that people would explode and die.

Li Yifeng, who had stabilized, frantically absorbed the essence of the pool water, and with the help of the power of chaos, transformed the essence into something useful to himself, and the chaotic dantian also reached its limit, and it only took one opportunity to break through the boundary.

However, Li Yifeng did not rush to advance, but first broke through the power of his physical body to impregnable gold, so that he could be sure to deal with the baptism of the Heavenly Tribulation after the advancement.

As time passed, the viscosity of the pool water was diluted by one percent, and Li Yifeng let out a loud sigh, and this bone-eating pool turned up, and all the acupuncture points in the body were fully opened, frantically absorbing the essence of the pool water.

"Poof!"

There was a sound of breaking membranes in the body, and the power of the physical body successfully broke through to the impregnable golden soup, followed by the surge of chaotic power in the body. The chaotic power of the four scurried had nowhere to go, impacting the nine dantians, and the small trees in the chaotic dantian grew wildly, giving birth to buds ten times larger than the other nine buds at the top.

The opportunity has come, Li Yifeng took out a jade bottle from the Ring of Chaos, and swallowed the entire bottle of pills without thinking about it, the pills in it were the Void Breaking Pill that helped to advance the refining period, and the medicinal power of the ten pills hit the limbs and hundreds of remains, and the omen of the catastrophe was attracted above his head.
