Inside the waterfall is a cave, and the fog in the cave is very strong, but it does not prevent you from seeing the road underfoot.

When Gu Youlan saw this cave, she instantly remembered that this was the stalactite cave when she first arrived in the valley, but the current cave was much larger than the first acquaintance, and there were more than ten hot spring pools with water mist in it.

The largest pool is the size of half a basketball court, the smallest is large enough for four people to bathe in the water, and there is a small stone cave in the innermost part of the cave, and there are three small pools for two people to bathe side by side.

"That's it, you pour a herb into it, Yuanji soup has the effect of quenching the body and cutting the marrow, it will make you very painful, you have to soak it in it until it doesn't hurt, if you can't stand it, say it now, don't waste my time!"

Yan's impatient voice made Gu Youlan's heart very uncomfortable, but she didn't continue to complain about anything: "I can, I can bear any pain, you just need to tell me how to do it." ”

"Well, you soak it for seven days in a row, and then talk about it after seven days." After speaking, Yan's voice disappeared.

The pool water was warm, warm and comfortable, and Gu Youlan closed her eyes very much with enjoyment.

There was a slight itch on the skin, followed by a faint stinging pain, a little bit of which was very penetrating.

Gu Youlan thought to herself, this Yuanji soup is really easy to use so soon, and then said to Bihe: "You go out first, just find a pool bubble, and call you when I am ready." ”

The pain deepened little by little, not very intense at first, but as the soaking time increased, it became more and more painful, and a wave of bone-eroding pain made her feel painful.

She quickly untied the hairband on her head and put it in her mouth to bite it, afraid that the pain would make a sound for Bihe to hear.

The pain was intense, from the bones to the tendons and veins to the skin, the bones were broken, the tendons and veins were broken, the skin was cracked, and the smell of blood mixed with herbs exuded a pungent blood.

The bones are connected, the veins are connected, the skin grows, and then the pain is boundless, from the beginning of the endurance, to the later madness, over and over again.

Eventually, she fainted in pain, but never made a sound.

By the time she regained consciousness, the pain had passed, and her bones, muscles, and skin were all intact.

Gu Youlan clenched her fists hard, and immediately felt that her whole body was full of strength, and her muscles and bones seemed to be thicker, "Well, it's still good, the effect is very significant, that old monster still didn't fool me, hehe!" ”

"Oops, it's dirty!" Suddenly, she smelled a foul smell, and suddenly opened her eyes, and instantly saw that she was covered in black mud, and it also emitted a foul smell.

She quickly got up from the pool, jumped into the pool next to her and quickly washed it, and after washing, she called Bihe to come over, change into clean clothes and go back to the room.

Sitting on the bed and feeling that the muscles and bones were ten times thicker than before, and the skin was fairer and smoother, she couldn't help but be secretly happy in her heart, not in vain for the sin she suffered during the day, thinking that such a sin would have to suffer for six days, Gu Youlan couldn't help but feel liver pain.

As soon as she put on her shoes and got off the ground to look at herself in front of the mirror, a very inopportune voice came out of her ears again, and her ears hurt.

"Rest early today and continue tomorrow!"

Gu Youlan gritted her teeth, rolled her eyes at the unoccupied room, quickly sorted out her clothes and went to bed, but she couldn't sleep.

Yan's purple eyes always lingered in front of her from time to time, her heart began to throb inexplicably, her mind was full of the scene when she first saw him, and her nose was filled with the fresh smell of grass, she couldn't help patting her forehead, what was wrong with herself? Why do you always think of him inexplicably? I couldn't help but sigh, and finally fell asleep in a daze.

After seven days of medicinal baths, Gu Youlan finally realized what the real human purgatory was, and the bone-eroding pain made her want to scold her mother several times.

But fortunately, from the third day, she didn't faint again, and the whole soaking process was sober, and Yan really admired that perseverance, after all, she was only a thirteen-year-old child.

After seven days, Gu Youlan was reborn as if she had been reborn, and her muscles and bones had expanded a hundredfold, and she was stronger than a person who had gone through the Heavenly Thunder Quenching Body during the foundation building period.

If you go through the tempering of the Heavenly Thunder again, the strength of the body and the talent of cultivation will undergo earth-shaking changes.

At this moment, she has more confidence in the future path of power, and she believes that she will eventually reach the highest peak.

After the invasion of Yuanji Soup, and then practicing the "Vain Sutra Mind Method" and "Spirit Quiet Step", Gu Youlan has made a qualitative leap, and the mental method has broken through the third level, and she can see her body inward.

The "Spirit Walk" has broken through to the second level, walking like flying, although it consumes a lot of spiritual energy, but it only takes a few seconds to run a thousand meters.

In the clearing of the valley, a blue light 'swished' past, and the wave of air that rolled up instantly swept down the small trees on the edge of the clearing, and Gu Youlan looked back at the clearing thousands of kilometers away, and the corners of her mouth hooked.

"This is really a home trip, tracking and escaping artifact, hahaha!" She grinned at the sky with her stomach in her hands.

"Don't get carried away, it's just a high-level spirit intermediate, this is just the beginning, it's still too far from my requirements, you have to start learning alchemy and acupuncture now!"

Yan's cold and stern voice once again penetrated Gu Youlan's eardrums without hindrance.

"Aren't I just a little proud?" Gu Youlan gritted her teeth and muttered quietly, this time Yan's voice did not reply.

"Cut, haunted all day!" didn't hear Yan's voice for a long time, and she suddenly felt a little lost inexplicably.

Dejectedly, she returned to the room and sat cross-legged on the bed, Gu Youlan looked inward at her body.

A colorful ball of light floated in the dantian, although it was only the size of a soybean, but it exuded a dazzling light.

Seven silk threads of different colors were methodically wound and rotated rapidly, surrounded by a rich aura, and the colorful mist wrapped her, from the skin to the tendons to the bones and finally converged in the dantian.

Gu Youlan happily looked at the small colorful ball of light, and in a moment, the corners of her eyebrows burst into a smile.

"Your Yuanji is still very small, it was originally a person who went through the Heavenly Thunder Quenching Body to generate Yuanji, and when it was first formed, it was the size of a grain of rice, and your current size is also the effect of Yuanji Soup!"

Yan's voice continued to come from time to time, "Don't be happy too early now, the Yuanji that has not gone through the Heavenly Thunder Quenching Body is very fragile, and only after the Thunder Tribulation can your Yuanji be regarded as the real Yuanji." ”

"Isn't the heavenly thunder quenching body in the foundation building period just one? I'm sure I'll be fine, and there is still the Tsukidan left by the master in the space, so I should be fine after taking it and going through the Thunder Tribulation, right? ”

Gu Youlan looked inwardly at her body and said to Yan in the soul space.

Now she is used to Yan's voice transmission from time to time, and if she suddenly can't hear it one day, she will feel strange.

"You can't use the Tsukidan left by your master, it's only for people with less than two attributes, and you are seven attributes, so it won't have much effect."

"If you take it even after the Thunder Tribulation, it will only have an effect on two of the attributes, then your remaining five attribute spirit roots will slowly stop growing, and as you grow, your seven attributes will also be unbalanced, and then you will really become a half-ass!"

"And what if I don't take Tsukidan?" Gu Youlan asked unconvinced.

"Don't you need Tsukidan?" Yan didn't expect this little guy to ask like this.

"Alas~ It seems that you still don't understand, the so-called foundation building heavenly thunder is the attribute thunder tribulation, and when everyone passes through the heavenly thunder quenching body, they fall with the attribute heavenly thunder according to the spirit person's own attributes."

"One attribute is a heavenly thunder, seven attributes are seven attributes of heavenly thunder falling at the same time, although there is only one, but the power is unbearable with the strength of your high-level spirit, when the yuan base is shattered, you will also explode and die, this is why I want you to soak the yuan base soup for the purpose!"

"And it's not enough to soak in the Yuanji soup." Yan explained very patiently, even he didn't expect that with his indifferent personality, he would explain so much to a little guy who had just met for a few days.

"Master! Then I should ......" Gu Youlan asked in a low voice, feeling a little helpless for the first time in her heart.

"Oh? Why is it so happy this time? But the sound was a little small, and I didn't hear it clearly! Although Yan's voice was a little cold, there was still a hint of banter in the aftermath of his voice.

Gu Youlan rolled her eyes, and couldn't help but slander in her heart, "It's still a master, it's always so out of tune." ”

Immediately, she opened her voice and shouted loudly: "Master! Master! Master! ”

"Ahem! Oh, okay, okay, Shizun is here, don't you want to be so loud, Shizun is an old man, and his ears are broken by your loud voice! ”

Yan heard Gu Youlan's shouts higher than one another, and he couldn't help shaking his ears with a sudden shock, but from the laugh lines that came out of the corners of his eyes, it could be seen that he was very happy at the moment.

Listening to Yan's words, Gu Youlan couldn't help laughing, and suddenly there was a trace of sweetness in her heart, and her face turned red in an instant.

Yan heard the little guy laugh, and couldn't help but straighten his face and continued: "Well, seeing that you are doing well today, as a master, then I will take some trouble to explain it to you." ”

"Yes! That has been taught by Master Lao. Gu Youlan arched her hand at the air in the room with a peach blossom smile on her face.

Yan coughed again suddenly, as if he was startled, and then exhaled and continued: "You can only find the horse clover and refine it into Tsukidan. ”

"But before that, you have to reach the alchemy level to the third grade, although your spiritual power and soul power have been significantly improved through the invasion of Yuanji Soup, but you don't have elemental spiritual fire in your body, you can only use your fire attribute to condense the internal fire first."

"What kind of fire is the elemental fire?" For the first time, Gu Youlan heard that there was such a thing as elemental spiritual fire.

"Elemental spiritual fire belongs to natural fire, which is the fire formed by the mutation of the attribute elements in the aura after absorbing the essence of the sun, moon and stars."

"Fire is divided into earth fire, sky fire, and divine fire."

"There are three kinds of earth fire, which are elemental spiritual fire, earth core flame fire, and alien beast spiritual fire."

"There are four kinds of heavenly fires, namely the desolate bone burning fire, the nether demon fire, the red lotus karmic fire, and the three-flavor true fire."

"There are three kinds of divine fires, namely the Eight Desolate Fire, the Blue Sea Heart Fire, and the Chaos Divine Fire."

"The above ten kinds of fires are what the world calls the top ten fires, with the Chaos Divine Fire as the head and the Elemental Spiritual Fire as the tail, understand?"

Yan patiently explained to her again, and Gu Youlan was stunned when she heard it, and once again realized that she knew very little about this continent.
