A cultivation cave mansion with a second-order spiritual vein was also extremely needed for Chen Lei.

Chen Lei walked around the cave and nodded, quite satisfied.

In his eyes, such a cave house is naturally not good, but it is the most suitable now, and the area for alchemy and refining is complete.

Although they are all some of the most basic Dan furnaces and utensils furnaces, as long as there are these basic things, Chen Lei can transform them into the best.

And Chen Lei's cave mansion also ushered in the first batch of guests, none other than Jingjing girl and Song Hongxian.

Miss Jingjing's origin seems to be really amazing, and she can come and go freely in the Xuantian Sect, and even the sect master of the Xuantian Sect treats the Jingjing girl with great courtesy.

When the Jingjing girl came to Chen Lei, she naturally came to collect debts from Chen Lei.

Chen Lei promised to help her refine the Purple Star Pill, and the price she paid was to hand over the storage ring in her hand and all the wealth in it, as well as the storage ring in Elder Song's hand and the wealth inside, to Chen Lei, and swore that she would not trouble Chen Lei after that. Including this period of time, Elder Song was at the command of Chen Lei at any time.

She had fulfilled these conditions without the slightest discount, but Chen Lei never helped her refine the Purple Star Pill.

And although the Purple Leaf Star Epiphany was temporarily sealed after Chen Lei used the Spirit Sealing Technique, the effect of the seal was only ten days.

If she can't refine the Purple Leaf Star Epiphany into an elixir within ten days, then this incomparably precious, thousand-year-old Purple Leaf Star Epiphany will be completely wasted, and at that time, even with the strength behind her, it will be difficult to find another Purple Leaf Star Epiphany in a short period of time.

Therefore, in the past few days when she came to Xuantian Sect, Chen Lei was not in a hurry, but Miss Jingjing was like an ant on a hot pot, although she received a very high standard of courtesy from Xuantian Sect, she was still restless.

Today, seeing that Chen Lei had a very short free time, he finally couldn't help it and came to the door.

Chen Lei let Miss Jingjing sit down in the living room of the cave, and said to Miss Jingjing straight to the point: "Miss Jingjing, I already know your intention. You can rest assured, I will never break my promise to do so, as long as the ten disciples of Xuantian Sect are over, I will immediately start alchemy for the Jingjing girl, and now, I have newly obtained this cave mansion, I have checked, an alchemy room in the cave mansion can fully meet the conditions for opening a furnace for alchemy, please rest assured. ”

When Miss Jingjing saw Chen Lei say this, she naturally didn't want to be reluctant, but repeatedly told Chen Lei not to forget the agreement between the two, and then said goodbye and left.

After Chen Lei sent Miss Jingjing away, he came to the alchemy room.

This alchemy room, with an area of about three hundred square meters, is a huge fire-gathering array in the middle, but this fire-gathering array is simply and crudely arranged, and it is just a first-order fire-gathering array.

"I still need to do a bit of work. ”

Chen Lei muttered to himself, and then began to renovate this gathering fire array.

I saw that one by one the materials flew out of the storage ring, and were refined into the fire gathering array by Chen Lei with extremely special means.

Gradually, this slightly rough fire-gathering array became more and more exquisite, more and more mysterious, and the patterns formed a precise formation.

When the last piece of formation material was integrated into the formation, the entire fire gathering array formed the shape of a fiery red fire lotus, and there were nine holes in the center of the lotus platform of the fire lotus, which was the eye of the fire gathering array.

"Okay, this second-order top-grade nine-hole red lotus gathering fire array is enough for refining second- and third-order pills, and even refining fourth-order pills can provide enough firepower. ”

Chen Lei inspected the Nine-Hole Red Lotus Gathering Fire Array and nodded with satisfaction.

"By the way, how about trying the effect of the Gathering Fire Array?"

Chen Lei flipped his hand, and an extra palm-sized fiery red medicine furnace appeared in his hand, and threw it to the center of the fire gathering array, and then punched in a seal, and this palm-sized medicine furnace turned into more than two meters high and stood in the center of the fire gathering array.

Chen Lei had another iron bone grass in his hand, and he shook his hand and threw this iron bone grass into the medicine furnace.

Then, one after another, spirit grasses of various colors flew out of Chen Lei's storage ring and fell into the alchemy furnace.

After a while, another spiritual spring was directly injected into the alchemy furnace, Chen Lei closed the door of the furnace, sat down in front of the medicine furnace, punched out one seal after another, and began to alchemy.

His alchemy this time was mainly to test whether the fire gathering array he had transformed was good or not.

After his personal experiments, he found that the effect of the fire gathering array was surprisingly good, and he could control the size of the fire as he wanted, which could well meet his strict requirements for fire when refining the pill.

Two hours later, Chen Lei suddenly opened his eyes, and two bright white lights shot out of his eyes, and Dan Cheng.

What he refined this time was the Iron Bone Quenching Pill used to strengthen the flesh, and the raw material was an extremely rare Iron Bone Grass, and the effect of this Iron Bone Quenching Pill was also extremely significant, after all, this was a unique Body Refining Pill in a Dan Dao Holy Land on another continent.

Chen Lei opened the Dan furnace and transported the pill harvesting formula, and eighteen black pills flew out of the Dan furnace.

These eighteen black pills, all round, the size is the same, there is a trace of mysterious veins hidden on them, and a cloud of medicinal qi emerges from these veins, in the blink of an eye, above these eighteen pills, eighteen Dan clouds formed by Dan Qi are condensed.

Chen Lei was a little overjoyed, but he didn't expect that just by casually trying to refine the pill, he actually refined the best Danyun Baodan.

Whether it is the Xuanyuan Continent or the other continents, the division of the pill is also very strict.

The pills are also divided into one to nine orders from the highest to the bottom. Each stage is divided into several grades, such as lower grade, middle grade, upper grade, best grade, and super grade, according to the different phases and medicinal properties of the pill.

Among them, the lowest level of the lower grade pill must also achieve the perfect fusion of medicinal efficacy, and the efficacy and Danfang can be consistent.

The medium-grade pill shows that the quality is perfect, and the medicinal effect exceeds the expression of the Danfang by two percent.

The high-grade pill has hidden Dan lines, and the medicinal effect exceeds the expression of the Dan prescription by more than 50%.

The best elixir must not only be in perfect condition, have Dan Wen, but also have Dan Wen, and the Dan Wen Chinese medicine qi rises, turning into Danyun, and the medicinal effect reaches more than three times that of Danfang's expression.

As for the super pill, then, not only must there be Danyun, and above the Danyun, there must also be a surge of light, called Danxia Baodan, and the medicinal effect is at least five times more than that of the Danfang.

In Chen Lei's previous life, he was able to refine the Danxia level Baodan.

Now, first, the cultivation is not enough, the second is that the fire gathering array, Dan furnace, etc. are not the top, and the third is that the medicinal materials are also lacking.

Therefore, Chen Lei is now extremely satisfied with the ability to refine a furnace of the best Danyun Baodan, as for the Danxia Extreme Baodan, at least in a short period of time, he should not expect too much.

"The physical strength of my body is really too weak, the last time I faced off with Ma Teng, I was actually inferior to a Ma Teng in terms of physical strength, which is also too embarrassing, just right, refining this furnace of iron bone quenching pills, first strengthen the physical body, and push the physical strength to an extreme. ”

Chen Lei looked at the eighteen top-grade Iron Bone Quenching Pills in his hand, and without hesitation, he sat down, swallowed an Iron Bone Quenching Pill into his mouth, and began to refine his exercises.
