Yusheng found a convenient place to sit down, put the ten grass tripods in front of him, stared at the patterns on the tripod for a long time, and took out a copper tripod, which was the "Longtao Ding" he exchanged from the exchange meeting.

The strange thing is that he didn't seem to have much interest in this tripod, but instead looked at the top cover for a long time, his eyes went back and forth between the top cover and the ten grass tripods, and he took a deep breath and changed the top of the top ten grass tripods.

A trace of imperceptible aura flashed, the top cover and the tripod body seem to be a whole, the gap can not be seen from all angles, and more importantly, the grass and tree patterns of the top cover mountain are exactly the same as the tripod body, there are ten kinds.

"Sure enough, it's the top cover of the Ten Grass Ding!" Yu Sheng's face couldn't help but be happy, the reason why he agreed to the exchange was because he took a fancy to this top cover, at that time he felt that the pattern on this Ding was a little familiar, but he didn't expect it to be the top cover of the Ten Grass Ding......

"With the complete medicine tripod, coupled with the fire of the earth lungs here, you should be able to refine the Quenching Bone Pill......" Yu Sheng muttered to himself, but he was still a little uneasy in his heart, and decided to test the water with the Bigu Pill first.

The elixir into the Ding, and then add mustard seeds, after the top lid is covered, Yusheng attracts the fire of the lungs, unexpectedly, the complete Ten Grass Ding is as much as half of the previous Bigu Dan time, and the refined pill is also a few more than the original, which is really a surprise for Yusheng.

Since this method is feasible, Yu Sheng will have already prepared the elixir of refining the Quenching Bone Pill into the medicine tripod, hesitated for a moment and put in the mustard seeds, covered the tripod, and slightly bent his index finger to attract the fire of the earth lungs.

As if the fire was attracted by something, it drilled into the tripod desperately, and in the blink of an eye, the entire medicine tripod was wrapped into a fireball, and the fire of the lungs in the magma was still constantly attracted.

Yu Sheng's eyes were fixed on the flames, while controlling the fire just enough to surround the medicine tripod, and at the same time preparing to cut off its fire root at any time, so as not to overdo it, so for three hours, Yu Sheng's forehead had already oozed a trace of cold sweat, and he threw the left back pill into his mouth without hesitation.

Suddenly, there was a slight vibration in the ding, and a series of popping beans sounded in the ding, and Yusheng's tense nerves seemed to have broken a string, and he quickly disconnected the fire, but he saw that the ten grass dings were still shaking, and with a "bang!", the top cover was lifted ten meters high, and a smell of burnt paste spread.

Yu Sheng's face was extremely ugly, and he looked at the ding, and found that it was extremely black, and occasionally there were two or three points of turquoise, which were the residues of the elixir that had not dissolved.

"How can this be ......?"

Loss is inevitable, in refining the Quenching Bone Pill, he has wasted two mustard seeds, this Pill is obviously only two pills, why is it so difficult to refine?

Yu Sheng put a finger into the ding, dipped a little green juice, stuffed it into his mouth and tasted it: "It is indeed an undissolved elixir......

Generally, there is only one possibility for this situation, that is, the fire used in alchemy is not good, logically speaking, the fire of the earth lungs is more than enough to refine the quenching bone pill, and now Yusheng can only blame the reason on mustard seeds.

"It seems that after adding mustard seeds, although it can increase the level of the pill and the chance of success, the requirements for the fire will also increase......"

However, this trip was not in vain, at least Yu Sheng realized this problem, since the alchemy failed, Yu Sheng simply began to ponder the clear water beads, and finally spent three days and three nights to make the first beads, not that his understanding was not good, but that the "clear water beads" he made were very different from the fat ones.

First of all, the amount of fire in the lungs is not on the same level, and besides, he does not use water, but sake!

The biggest difference between Daigo Bead and Shimizu Bead can be used against the enemy, after all, it is a fine wine, and it only needs to be ignited when it is thrown, which can naturally trigger the fire of the lungs in it, as for its power, Yusheng is not in a hurry to test, but it will not be bad.

After all, the fire of the earth lungs itself is not an ordinary fire, and Yu Sheng compresses so many flames into a little flame, and under the trigger explosion, the power is not trivial, and it is a good choice to make his unexpected killing move.

In a few days, Yusheng used all the sake in the sake bottle to make Daigo beads, there were hundreds of them, and if they were sprinkled with them, the Jindan monks would have to retreat.

After doing everything, Yu Sheng did not rush to leave, but released the black feather that he hadn't seen for a long time, this little guy has really not been honest recently, who would have thought that the little bird that was originally too lazy to be born, now jumps down the mountain, chirping, flying around Yu Sheng, that seemingly short wings are really powerful, and every time it can make Yu Sheng feel a burst of hot wind.

Yu Sheng grabbed the black feather, and after looking for a long time, he found the pair of black eyes, and said: "I have wronged you for so many days, this place is full of fire from the lungs, you can eat enough at one time!"

Black Feather struggled, her wings fluttered, her head shook like a rattle, and she let out a series of piercing chirps.

Yusheng's face was strange, and he found that the little guy in his hand, although the movements were funny, but the two short wings always pointed at the mustard grass from time to time, and the long hair on the top of his head began to emit a puff of green smoke, which seemed to be ignited in the next moment.

"Do you want to eat that unicorn ginseng?" Yu Sheng wondered, and seeing the little guy nod, Yu Sheng began to think about countermeasures.

Qilin ginseng is useless to others, but it is of great use to him, he can wait for thousands of years, this is a long-term investment, and its value will not only increase thousands of times when the time comes? The elixir of refining the six-grade elixir itself is unattainable......

In Yu Sheng's view, unicorn ginseng may be like a delicacy to black feathers.

And Black Feather doesn't have the dietary characteristics of Chongming Bird at all, and he is not interested in sycamore and nectar, except for the flame, unicorn ginseng is what Yusheng has ever seen, and Black Feather is most interested in.

Although he was reluctant, when Yu Sheng saw the pitiful appearance of the little guy, he still couldn't help but take out the unicorn ginseng, and Hei Yu didn't know where he got the strength, he broke open his palm and swallowed the unicorn ginseng cleanly, Yu Sheng didn't even see how the other party swallowed it.

Yu Sheng was stunned for a while, the size of the unicorn ginseng is larger than the size of the little guy, where does the other party's stomach have such a large space? And this small mouth is completely disproportionate to the unicorn ginseng, not so much that he swallowed the unicorn ginseng, but that it sucked it in, like drinking water......
