Li Feng disappeared into the stone wall in an instant, Wang Dan and Canglong glanced at each other and saw the look of shock in each other's eyes. The two stepped forward and knocked on the stone wall, making a clanging sound, and a guess emerged in their hearts, could it be that this was a wall-piercing technique?

At this time, Li Feng was already in a three-zhang square cave.

There is a stone bed on one side of the cave, there is a stone pillow at the head of the bed, and a stout stalagmite hangs upside down in the middle, the tip of the bamboo shoot is facing a one-foot-square stone pit on the ground, and a shallow layer of milky white liquid accumulates in the pit, and the whole stone cave is filled with a rich fragrance, and Li Feng feels comfortable when he takes a sip.

"Xiaohua, look at what this stone milk is?" Li Feng's mind transmitted.

"Oh my God! This stone milk should be the essence of Wanhua Heaven, and there are so many, you are developed!"

"Wanhua Heavenly Marrow, what is it for?" Li Feng asked.

"Heal and replenish the true element, just the little bit of true yuan you have now can be replenished with a drop. ”

"Can you use it to cultivate?"

"Master, do you want to use it to cultivate? Halo, you are a tyrannical thing! Of course a low-level monk can, and the effect above the foundation building period will be minimal. ”

"It's good to be able to cultivate, as long as the effect is good in this world where the aura is thin, it doesn't matter if it's precious or not. By the way, what is the effect of the third layer of Qi refining like me?"

"That's true, if you refine all these heavenly marrows, it is estimated that you can rise to the sixth level of qi refining, but I advise you not to use it up in one go, otherwise when it comes to breaking through the foundation, there is a high probability of failure. ”

"How do you use that?"

"Breaking through the first layer and saving it for the breakthrough to build the foundation can increase some of the chances of success. ”

"I don't know if I can break through in the Year of the Monkey. ”

"Cultivation is the most taboo and impetuous, you have to take your time one step at a time, and the cultivation that relies on external forces like you is not the right path after all. ”

"I know, but no matter what the strength is, as long as you can cultivate to the Jindan stage. ”

"Master, why are you doing this?"

"In order to fulfill a grand wish, you can leave this world and go to the Xiuzhen Continent in the Jindan period. ”

"Xiuzhen Continent seems to be familiar, but I can't remember it for a while. ”

"Don't talk about that, or help me see what other mysteries there are in this cave?"

"Don't look at it, except for the stone milk, there is something under the stone pillow, nothing else. ”

Li Feng came to the stone bed and picked up the stone pillow, and sure enough, there was a small square pit under the stone pillow, and there was a stone that looked like gold in it.

"What is this?"

"It's Taiyi Golden Essence!" Xiaohua's thought came out in surprise.

"Is this the Taiyi Golden Essence, the main material for refining the high-grade magic sword!"

"Master, you know, it seems that there is a master to teach you. ”

"Well, even if it's it, don't talk about it, I'll cultivate first. ”

Communication was interrupted. Next, Li Feng took out a few wine bottles from the storage ring, and sucked not a drop of Wanhua Tianpi into the wine bottles, filling more than two bottles.

Li Feng picked up a bottle of stone milk and took a small sip, and in an instant, a warm current rushed straight to the dantian, and in a breath, the true yuan he had lost when he released the Sun and Moon Divine Arrow just now instantly refilled, and there was even a surplus, which seemed to expand the dantian a little.

What a treasure!

Li Feng no longer hesitated, picked up the wine bottle and poured a big mouthful of Wanhua Heavenly Marrow. This is amazing, the warm current is like a rushing river, washing back and forth in the veins of his whole body, and finally flowing into the dantian like a flood irrigation.

A huge pain came, and beads of sweat the size of beans came out of his head. He gritted his teeth and held back, feeling that the dantian was constantly swelling like a fire, accompanied by severe colic.

It didn't take long for the sharp pain to disappear, the true yuan in the body was surging, the dantian was bigger, and the cultivation reached the peak of the third layer of qi refining, just waiting to break through.

It wasn't enough, Li Feng ruthlessly picked up the wine bottle and drank two sips of Wanhua Heavenly Marrow.

This time, the great pain was even worse, and the muscles and veins of the whole body continued to expand under the impact of the airflow, and Li Feng felt that the muscles and veins were much thicker, and soon they became saturated and no longer expanded.

Finally, the excess airflow goes straight into the dantian, squeezes and squeezes again, and fills the dantian little by little. During this process, Li Feng trembled in pain and was drenched in cold sweat.

The dantian had already reached the critical point of breakthrough, and after such a plug of the air flow, there was a loud "buzz" in Li Feng's mind, and the bottleneck of the fourth layer of qi refining was blasted open, and he stepped into the fourth layer of qi refining.

It's not over yet, the excess airflow is poured into the dantian that has expanded a lot, and the dantian is filled again, and it continues to expand, at this time, the pain is much smaller, and the dantian is swelling and expanding, until the peak of the fourth layer of qi refining does not stop.

Li Feng felt that the true yuan had grown a lot, and his divine soul had also advanced a small realm.

Li Feng put the remaining Wanhua Heavenly Marrow into the storage ring, and then took out the Qiushui Sword and the Golden Crowding, he wanted to try to melt the Qiushui Sword and add Taiyi Gold to refine a natal sword that belonged to him.

The biggest difference between the natal weapon and the ordinary weapon is that the natal weapon can grow, and it can be advanced under certain conditions, plus it is connected to the owner's bloodline, so it is even more powerful. Ordinary magic weapons are difficult to advance, and they can't be like natal magic weapons.

In his cultivation memory, there is a method of refining, as long as the conditions permit, the monk can refine his own natal weapon when he reaches the first level of qi refining, but with the help of external fire, such as the earth-centered lotus fire, the black flame fire, and the ten-direction karmic fire... and so on, there must also be elixirs or treasures to restore the soul.

He doesn't have a Dan Fire Refiner, but he has the True Yuan Fire, although it is not at the same level as the Dan Fire, but with the blessing of the Golden Crow, he can barely refine it.

In terms of the divine soul, he has a soul nourishing bead, and it is not a problem to replenish the consumption of the divine soul, and now that the conditions have basically been reached, it is no wonder that he is itchy and wants to refine the natal sword in advance.

At this time, he had expectations in his heart, with the Natal Sword, he could fly with the sword, of course, with his current cultivation, it could only be a short flight.

Li Feng picked up the Taiyi Golden Essence and put it aside, sat cross-legged on the stone bed, and calmed down to review the process and essentials of refining the Natal Sword from a new perspective, so as to be familiar with every detail.

Soon, he stretched out his fingers and shot the True Yuan Fire into the Golden Crow.

"Buzz"...

The rune at the bottom of the Golden Crow Ding lit up, and then the three-legged Golden Crow on the wall seemed to come to life, and with a loud "chirp", a flame spat out from his mouth.

Li Feng took the opportunity to insert the Qiushui Sword into the Ding, and his True Yuan Fire was more than twice as high as the temperature under the blessing of the Golden Crow Ding.

It takes time to melt the device, and it also needs Li Feng's continuous injection of True Yuan Fire.

As time passed, the Autumn Water Sword turned red, and the last bit melted into a cloud of silver liquid. At this time, he threw the Taiyi Golden Essence into the Golden Crow Ding, increasing the output of the True Yuan Fire.

Finally, when his true yuan was about to be exhausted, it melted into a ball of golden water, mixed with the silver liquid. He breathed a sigh of relief, and the first step was successfully completed.

The next step is condensation, this step consumes a particularly large amount of divine soul power, which is not at all something that a monk in the Qi refining period can bear, and a monk in the late stage of foundation building can only succeed.

Li Feng relied on the replenishment of the soul nourishing bead to the divine soul and began to condense, he pinched the casting technique in his hand, and the true yuan revealed with the casting technique, entangled the mass of metal liquid. The Divine Soul was dual-minded, controlling the temperature of the flame in the Dingzhong and slowly lowering the temperature, while kneading and controlling the True Yuan, elongating the metal liquid according to the sword shape he thought in his heart.

As the temperature drops, the liquid metal slowly solidifies and hardens, and it has to be molded in a very short time, and this process consumes souls.

After replenishing the Divine Soul a few times, it was kneaded and modified into the shape of a sword, and every slight change was a massive consumption of the Divine Soul.

Half an hour later, a sword took shape. Li Feng withdrew the True Yuan Fire, waited for a while, and before the sword was completely solidified, his fingers drew three golden runes in the air, and at the same time released the divine soul attached to the three runes, and scolded lightly in his mouth: "Go!"

The three runes immediately drilled into the sword body, and the sword "buzzed" for a while, and then the light shone brightly. Li Feng was overjoyed when he saw this, and immediately forced out a mouthful of essence blood and sprayed it on the sword, and with a "snort", the blood steamed, and most of the essence blood seeped into the sword body, and immediately his mind had a trace of connection with the magic sword.

It was a pale golden magic sword, which looked very ordinary, and did not emit light. But he knows that the magic sword does not need to be sharp, but the quality is good, and his magic sword is a high-grade magic sword, and it is a natal magic sword, which can be contained in the dantian in the body.

Li Feng said in his heart: This is the magic weapon sword he has refined for the first time, let's give it a name, just call it "Dao Yi Law Sword".

Li Feng pinched a magic trick and his mind moved, and the Dao One Magic Sword suddenly shrank into an air sword and burrowed into the dantian. Looking at the dantian inside, there was a small golden sword inside, sinking and floating in the sea of true vitality, nourished by his own essence and blood.

Next, Li Feng cultivated the Purple Mansion Soul Dementoring Dafa for a week, and his divine soul was restored to its peak.

After thinking for a while, he took out two empty wine bottles, filled them with some stone milk, and left the cave according to the original method.

Outside the stone wall, Wang Dan and Canglong saw Li Feng squeezing out of the stone wall again, and Rao is two were also embarrassed when they saw a lot of knowledge.

"Li Xiaoyou is really a fairy, he can actually penetrate the wall, I don't know what is inside?" Wang Dan asked curiously.

"An ancient's cultivation cave, I have gained some benefits in it. Li Feng told the truth.

"Then congratulations to Xiaoyou, Xiaoyou's chance is really good. Wang Dan didn't blush, and sincerely said goodbye.

"That's good, I'll give you some stone milk that you got inside, this stone milk can heal injuries, and even a drop of even a serious injury can be cured instantly, just like the injuries suffered by the two elders just now only need half a drop. After Li Feng finished speaking, he handed the wine bottle in his hand to the two of them.

The two hurriedly thanked, it was really a life-saving medicine as Li Feng said, but such a treasure medicine was contained in a wine bottle, which made people laugh.

"Sect Master Wang, if the Yunlan Sect comes to seek revenge, you can contact me immediately, and I will settle the matter together. Li Feng promised.

"Thank you, little friend. Wang Dan thanked.

"The two of you, since this is the matter, I will leave here, and I will meet again. ”
