Yu Pu returned to his cave, he did not sit down to rest, directly from the stone path of the stone wall to the bottom of the valley, here there are rocks and trees, the terrain is very uneven, but almost no one comes here, very remote and quiet.

After walking half a mile into the valley, Yu Pu finally found a relatively flat place, and it was also a mountain recess, so he set this place as a place to practice in his heart, and tidied up a little, Yu Pu transferred the knife skills and body skills he saw at noon from his mind, took out the hook knife in the ring, and began to practice.

Splitting, hanging, and chipping...... Angle, orientation, rotation, jumping, and volunting...... The speed, the mixture of weapons, one by one, and combined with his own whirlwind step, Yu Pu practiced well, and an afternoon passed like this.

At the end of Shen and the beginning of the year, Yu Pu finally felt a little hungry, and was about to make a fire to cook, when he suddenly remembered Bigu Dan, this Bigu Dan was very sought-after by listening to the seniors of the Dan Palace, and it was conceivable that he saved a lot of meal time in the process of cultivation, and sold well in the academy, which was also reasonable, and he wanted to earn star coins, so he could start refining Bigu Dan, but how could he refine Bigu Dan that was better than Dandian?

"Dan Lao, Dan Lao ......" I have to consult Lao Dan about this matter.

"Silly boy, what's the matter?" came Dan Lao's voice in his ears.

"Is there a better Bigu Dan recipe than the usual Bigu Dan?"

"Bigu Dan is the foundation of alchemists, and its main materials are some energy retention of Zhicao Qinshen, if you want some special effects of Bigu Dan, of course I have it here, and it is a special effect of Bigu Dan, this Dan recipe in some ordinary medicinal materials to add some mushrooms, mysterious beast blood, the effect is definitely better than the ordinary Bigu Dan, however, refining this special effect of Bigu Dan, you need a relative supply of spiritual power to be sufficient, you are not in the place you are now, well, in this way, you go a few miles deeper, see if there is a more remote place, and then take out the spirit gathering array and the pregnant spirit cocoon, and then alchemy, it is estimated that it is okay......”

"That's great, give it to me."

"Okay, then let's go, I'll help you pay attention to which one in this valley is more ideal."

Yu Pu was sure in his heart, and then went deep along the valley floor, the trees, streams, and weeds moved back one by one under his feet, and when it was almost evening, Lao Dan's voice finally came from his ears: "Ten meters ahead, there is a cave, this cave seems to be connected to the spiritual source under the mountain, that place should be good......"

When Yu Pu heard this, his spirits were lifted, and he hurriedly ran over, and found that this was a small mountain, inconspicuous, lonely in the midst of the mountains, and he approached and swept around, and sure enough, there was a cave on the back side of the mountain, and the grass at the entrance of the cave was very hidden.

The cat's body drilled in, found that the cave was relatively low, in the shape of a gourd's belly, there were four or five round mouths in the middle of the cave, the big one was as big as a basin, and the small one was only the size of a fist.

Hung two wind lanterns on the stone wall, Yu Pu was about to put down the spirit gathering array against the wall, but heard Lao Dan say: "You put the spirit gathering array under the mouth of the sky, above the hole in the ground, ......"

This means that the Spirit Gathering Array is placed below that opening, above the hole in the ground, and what if it rains?

Yu Pu didn't think about it so much, the four yin and yang treasures were arranged in the direction, the pregnant spirit cocoon was placed in the middle, and the person also sat down on the pregnant spirit cocoon and took out the pill given by Lao Dan.

The medicinal materials in it were all in their rings, and there were a lot of them, including beast blood, and they took out the Quartet gilt furnace at the moment, ready to start alchemy.

Gathering spirit yin and yang gems, Hongqiao illusion, for a time, the cave is full of light, and the strange image is bright.

Gathering the four treasures of the spirit, absorbing the aura of heaven and earth, and collecting the essence of the four directions of the pregnant spirit cocoon, at this time, the faint fog visible to the naked eye in the valley began to gather, gradually condensing in the sky above the mountains, diffusing but not dispersing.

When the spiritual power was spit out, Yu Pu felt a powerful spiritual power at the mouth of the day directly poured into his Baihui, and then quickly exploded on the meridians in his body, spurting in all directions at once, and when Jiahuo and Rong Zhu came out, he also clearly felt the joy of Jiahuo and Rong Zhu's excitement.

A furnace of Jiudan Bigu Dan, extremely smooth, when the telekinesis lifted, Yu Pu found that his spiritual power was not only not consumed, but had the feeling of building an embankment to raise water, this feeling of overflowing and swelling, the only explanation is that the spatial realm of soul power has improved.

The thumb Dan tube entered the cylinder one by one, all of them were Danwen quality, Yu Pu was happy in his heart, made persistent efforts, took out the ratio of medicinal materials again, turned his mind into mud, and refined a furnace of Jiudan, haha, it is Danwen quality again, or else, another furnace, okay, then another furnace, the third furnace of Jiudan, and Danwen quality, this place is full of spiritual power, and it is not a problem at all.

Isn't it said that Bigu Dan is the most sought-after pill in the Seven Star Academy, then I will refine it again, Yu Pu thought so, and did so, until the medicinal materials of Bigu were exhausted, and a total of thirty-three furnaces were refined, two hundred and ninety-seven pills of Bigu Dan, the quality of the grain Dan pattern, and there was no loss of soul power, but it became more and more vigorous, and even a little swollen and overflowing.

Yu Pu looked at the sky, it was still dark night, and the spiritual power in his body was so full that he had an urge to get up and dance, so he decided to flush the sixth meridian, and initially estimated that it would be almost tomorrow morning.

The sixth meridian of washing: the hand sun and small intestine meridian

"Shaoze has suction, Houxi is connected, Qiangu is connected, Yanggu is three-breathed, Zhizheng Yongyi, Xiaohai is not perched, Tianzong vortex, and the wind is strong...... Listen to the palace Qingjie"

Yu Pu followed the mantra in the rush, breathing, sucking, stopping all the way to rinse, at this time the spiritual mist on the mouth of the sky was no longer at the entrance of the cave, they moved down to the hole, as if there was some strong suction force to pull them over, until they reached Yu Pu's gathering array, and then slowly turned lightly, slowly becoming thick and thick, just like the filigree of cotton, circle by circle to surround Yu Pu in the cocoon of the pregnant spirit, and the light mist in the entire valley seemed to be good, one after another gathered here, methodically waiting to enter the place in the mouth of heaven.

Yu Pu, who was in the spiritual mist, was unconscious, he was already intoxicated with the scriptures, he had already closed his eyes, and he didn't see this unnatural scene, otherwise, he didn't know what he thought.

Bang, bang, a soft sound like popping beans sounded on Yu Pu's body, but Yu Pu still didn't open his eyes and continued to enter the sixth meridian washing.

The black night turned gray, and then gradually brightened, the birds in the mountains and forests, the stream in the stream, and the grass outside the cave began to make a clear sound due to the slight friction of the wind, and it began to make a clear sound into the ears of Yu Pu, who was sitting and breathing, he opened his eyes and exhaled a large breath of turbidity, this sixth meridian, obviously improved his hearing and soul power, so he opened his inner eye:

"The first level peak ...... in the early stage of martial arts"

"Fourteen thousand five hundred ...... power"

"Soul Master Late Ninth Level ......"

"Sixteen thousand five hundred ...... soul power"

"Eighteen thousand ......"

"Attributes: Fire, Wood, Fire +2, Wood +2......"

"Weak ...... in the realm"

"Xiudan's superior general ......"

These data undoubtedly prove that the cultivation has improved a little, but if you want to get more learning opportunities in the Seven Star Academy, the most fundamental thing is the star coin, Yu Pu looked at the sky dyed red by the rising sun, and had some plans in his heart.

Bigu Dan, if it is sold at the price of the free trading area, it is 80 star coins a grain, and 300 Dan is only 2,400 star coins, and now the medicinal materials of Bigu Dan have been used up, buy medicinal materials, study subjects, and in the library, there is not yet to go, listen to what Dean Wei said, the use of the book is also a non-trivial expenditure, all of this involves star coins, a little more than 2,000 star coins are far from enough, yes, arrows can also be sold, after the coat of arms, and stars can also be, what else, diversification, is it more able to drive business, that should be......

Yu Pu thought of diversification, so Dan Jiao, arrows, and stars, so what else? Boning knife, yes, in addition to the one given by Wen Jie in his ring, there are also three boning knives, all of which are engraved with heraldry, so he thought of it, took out a boning knife, and prepared to engrave the coat of arms of the blade, at this time, his mind showed a little spiritual fire point stock solution, this method, to minimize the waste of stock solution, also try.

A little spiritual fire popped out, passing a little on the original liquid, but it still felt a little too much, enough for three boning knives and two stars to engrave the liquid, this still needs to be practiced.

After all these things in the plan were done, it was already broad daylight, Yu Pu collected the Spirit Gathering Array, returned the same way, passed by a puddle of creek pits, and washed it off, washed off the sewage and sludge on his body, and returned to the cave where he lived.

At that time, today is the first lesson of the heraldic hall, of course Yu Pu can't be left behind, the other six people are already in the classroom, the lecturer in the class is surnamed Fang, the age of thirty-eight and nineteen, he is a student of Elder Cui, and he talks about the history and development of heraldry, of course, this is a little boring, but after all, it is the first class, and the seven people in the class are also listening carefully.

At noon, the class ended, and Yu Pu rushed out of the classroom in a hurry and rushed towards the transmission array, not even seeing Xin Yi's greeting from behind.

Free Trade Zone, Xiaojianghu, I'm here.

In the free trading area at noon, the flow of people is not very much, and there are many empty stalls, Yu Pu looked for it, ready to find a stall that is not a prosperous shop but is not very cold, and looked at it, and came to the stall of 3721, which is also empty.

Forget it, that stall is also selling things, just this stall, Yu Pu thought for a while, took out his identity card, and pasted it on the card swiping table, and the text appeared on it, 20669, Yu Pu, Academician Mingdian, please enter the time......

Yu Pu pressed two on the number button, whew, the text on the display flashed, Mingdian academician, Yu Pu, number: 20669, hour: two, and below are a few words that flashed by "deducting star coins forty"

It's okay now.,There's only ten star coins in the identity card.,If there's no business.,Haha,How should I live this day.。。

Yu Pu ignored these, he walked into the stall, wiped it on the table, took out the Dan tube, and then took out a card, which read: "Dan pattern Bigu Dan, eighty star coins a grain", then took out three arrows, a piece of star and a boning knife, and took out the card, which read "Wind Arrow, 10 Star Coins, 10 Star Arrows, 15 Star Coins, Ice Arrow, 20 Star Coins, Sharp Star, 50 Star Coins, Edge Crest Yi Bone Knife, 200 Star Coins" ......"

Once it's written, it's neatly arranged, and then sit in a chair and wait for customers to come to the door.
