Violent mana fluctuations came from the top of a strange rocky peak, and from time to time there were bursts of roars, and the river of Yellow Springs flying in the sky occasionally smashed to the ground, making the earth tremble for several kilometers.

By the time everything had calmed down, it was already half an hour later, and the top of the mountain, which had been covered with black reefs of various shapes, had turned to fly ash at this moment, and the entire summit was full of broken rocks and messy potholes.

A tall woman in a pale blue robe was standing on top of a flattened rock at the top of the mountain, with a dark-skinned monster lying at her feet. The monster's eyes protruded, and its sharp fangs even pierced out of its lips, and through the blue-black skin, the muscles of the monster's body could be clearly seen like steel.

This is a ghoul, a very troublesome monster in this fantasy world, with thick skin and infinite strength, and it is not at the same level as the silver-white skeleton.

But such a monster only lasted for more than half an hour in the hands of the woman in the light blue shirt before turning into a corpse.

That woman was Tang Yun.

It had been more than three months since she re-entered the illusion, and this time she appeared in a volcanic place, and after comparing the map given to her by Long Aotian, it was confirmed that her location was in an area in the south of the illusion.

Although a full three months have passed, maybe Wang Sufang has already hung up, but Tang Yun, who has not received definite news, still decided to rush to the Great Gobi in the north to try to see if he can find any trace of Wang Sufang or Long Aotian.

The initial journey went well, but after she left the volcano area and entered a black area marked on the map that Long Aotian had given her, she ran into a steady stream of trouble.

The area marked black is a large rocky mountainous area, which is full of strange ghosts, silver skeletons and ghouls are relatively common, and some other rare ghosts can be encountered here frequently.

Some of these ghosts were tangible and insubstantial spirits, some were corpse flowers like plants, and even Tang Yun had seen a giant beast that seemed to be spliced together by countless corpses.

Some of these ghosts are weak, some are powerful, but even the weakest ghosts have strange abilities, just like the kind of corpse flower that can't move, the strength is very weak, but its pollen contains highly poisonous, and it is colorless and tasteless, and it is extremely weird.

Fortunately, the poison of this corpse flower was not like the poison of the person in the Heavenly Demon Palace before, it was able to devour mana and strengthen itself, otherwise Tang Yun would have died dozens of times.

Sighing in his heart for what had happened to him during this time, Tang Yun kicked the ghoul under his feet away and took out a jade plaque from the storage bag, which recorded the points she had earned in the illusion.

"Three hundred and twenty-eight! I actually killed more than 300 ghosts without realizing it, it really makes me unbelievable!" Tang Yun muttered a few times, and then checked the things that could be exchanged in this jade card.

There are a lot of things that can be exchanged through this jade card, and from pills to top-level magic weapons, it can be said that everything Tang Yun can imagine can be exchanged here.

However, Tang Yun didn't pay attention to the pill magic weapon, but quickly skipped the part of the pill magic weapon and began to check the secret techniques that could be exchanged in the jade card. You must know that this place is an illusory trial illusion, her current body is illusory, her cultivation is illusory, and the elixirs and magic weapons she gets are all illusory.

The only effect of these illusory things was only to improve her ability to survive in the illusion, and they were not beneficial to her own cultivation at all.

However, the secret techniques of the exercises are different, although the secret techniques of the exercises cultivated in the illusion realm cannot be brought to the body, but these secret techniques can be firmly remembered, and the comprehension of the secret techniques of the exercises, and even the experience of cultivation can also be recorded, and these secret techniques can be re-cultivated soon after returning to the body.

At this time, what Tang Yun was looking at was the part of the jade card that exchanged the secret technique of the exercise, and she had taken a fancy to a technique called the basic alchemy technique a long time ago.

Tang Yun once got a crippled physical training method from Wangjiazhuang, and it was that physical training method that improved her physical strength a lot, and even she was able to condense her spirit, and that physical training method also played a great role.

It is precisely for this reason that Tang Yun has always been extremely attentive to the practice of physical exercises, but unfortunately, the exercises for practicing physical exercises in the cultivation world are extremely scarce, and almost all of them are in the hands of those big sects and big families, and almost all of them are scattered in the outside world, and most of them are not as good as what she gets.

It wasn't until he entered this trial illusion for the second time that Tang Yun, who had never remembered the jade plaque, finally came back to his senses after killing hundreds of ghosts in a row, and he had points for killing ghosts in the illusion, and the points could be used to exchange for various rewards.

Tang Yun, who reacted, quickly found the exchange area of the secret technique from the jade card, and looked at the dazzling array of goods on it, almost dazzled.

There is the second half of the Huangquan Creation Sutra on it, as well as the Nine Heavenly Books, the main practice of Emperor You, and even Tang Yun saw the exercises of the Ghost Hill, an exercise called the Primordial Demon Codex.

There are a lot of things, but unfortunately, each of these exercises and secret techniques costs tens of thousands of points.

You must know that every trialist only needs to obtain 10,000 points to choose to end the trial, but these exercises require as many as tens of thousands of points!

And what made Tang Yun scold his mother was that the secret techniques listed in the jade card were not only those top-level things that were expensive, but also some low-level goods that were also prone to thousands of points, and only some common road goods would be below a thousand points.

That basic body alchemy technique was the cheapest physical practice method that Tang Yun had found from countless classics, but even so, it would require a full three hundred and twenty-eight points.

It wasn't until today that Tang Yun, who had killed the ghoul just now, had finally gathered the points and was ready to redeem this physical exercise that she had been looking at for a long time.

Without thinking much about it, Tang Yun stretched out his hand and clicked on the rune of the Basic Alchemy Technique, and almost at the moment she clicked it, the number of points recorded on the jade plate of three hundred and twenty-eight was cleared, and the information flow suddenly appeared in her mind.

That information flow was the cultivation method of the Basic Body Alchemy Technique, Tang Yun took a cursory look at it and didn't pay attention to it anymore, but his body flickered, turning into a Yellow Spring Phantom, and in an instant, he flew out several kilometers away.

After flying for more than half a day, Tang Yun finally found a hidden cave under an inconspicuous small peak, and after easily killing the silver-white skeleton inside, he took this cave for himself.

Casually moving a large stone to block the entrance of the cave, Tang Yu began to seriously comprehend the basic alchemy technique he had newly obtained.

After such a long period of practice, Tang Yun's horizons gradually widened, it used to take a long time to comprehend a technique, but now it only took her less than twenty minutes to fully comprehend the basic alchemy technique.

This alchemy technique is not complicated, its principle is to use one's own true qi or mana to feed one's body, and there are not too many barriers and bottlenecks in cultivation.

The only trouble is that this exercise will be very painful to practice.

"Could it be that it hurts to practice the physical exercises?" Tang Yun remembered the fragments of the physical exercises he had obtained in Wangjia Village, and the practice of those exercises would also produce severe pain.

This thought was just turned in his mind for a moment and then he was put down, and then Tang Yun didn't hesitate any longer, the mana in his body worked rapidly, and he began to temper his body according to the method of basic alchemy.

With the surge of mana, Tang Yun immediately felt a sharp pain all over his body, and even the muscles, epithelium, and bones on his body were cracked apart with a "click" sound. Threads of blood flowed out of the rupture of the epithelium, and streams of blood donations kept coming out of the mouth, nose, eye sockets, and ears.

Almost instantly, Tang Yun's body was seriously injured by his own mana!

Tang Yun, who was taken aback, hurriedly stopped the cultivation of the basic alchemy technique, and the Taiqing Hui Immortal Technique even subconsciously operated, and the mana in the spirit platform decreased rapidly, and all the scars on his body were repaired in a short time.

Tang Yun, who felt that her whole body was recovering from her injuries, let out a long breath, just now she was almost on the verge of life and death, if her speed was slower a little, she couldn't say that this second chance to die would be wasted.

Recalling the situation just now, Tang Yun took a breath with some trepidation, she didn't expect that there would be such a dangerous accident when it was just the cultivation of the most basic exercises.

Tang Yun, who was a little unclear about the situation, turned around and carefully understood the basic alchemy technique in his brain, and soon found the reason, but this reason made her a little crying and laughing.

The basic body refining technique is the basic method cultivated by people in the Qi refining period, and when cultivating, it is like a blacksmith beating an iron block, beating the flesh with his true qi, removing the magazines in the body, and beating his flesh and blood body more tenacious.

Tang Yun's cultivation method is not wrong, but now what is surging in her body is mana, not true qi, beating her body with true qi is like using an iron hammer to beat the iron embryo, but using mana to beat the flesh is like using a 10,000-ton hydraulic press to beat the iron embryo.

Her physical body can't withstand the tempering of mana at all!

Now that he had found the problem, Tang Yun didn't delay any longer, and quickly channeled a wisp of mana, and under the control of her divine thoughts, that wisp of mana quickly atomized and dispersed, and after a while, it was transformed into a large stream of innate true qi that was so pure that it made the innate cultivators feel terrified.

Controlling this innate true qi to operate according to the method of basic body alchemy, although there was still severe pain coming from his body, there was no sign of collapse.
