According to the conventional proportion, one high-grade yuan stone is equivalent to 10,000 low-grade yuan stones.

However, most of the time, 10,000 low-grade yuan stones and 100 medium-grade yuan stones will definitely not be exchanged for a high-grade yuan stone!

In the high-grade yuanshi, it not only contains abundant vitality, but also the degree of purity of the vitality is far more than that of the middle and lower-grade yuanshi.

Imagine......

Two Jindan realms with similar talents use medium-grade and high-grade Yuan Stones to cultivate respectively, the former requires a lot of effort to completely refine the Yuan Qi, while the latter only needs to spend a little effort to do exactly the same thing.

In the long run, the judgment will be made.

There are also some high-level magic circles, secret treasures, etc., if the quality of the Yuan Stone is not high enough, no matter how much it comes, it will not be able to drive it.

"A high-grade Yuan Stone...... That's it?"

Looking at Chen Xiao's back, Xia Churou's eyes widened.

The speed at which Chen Xiao solved the puzzle was really shocking, so much so that until now, she still seems to be in a dream, with an unreal illusion.

Click!

Click!

And at the same time that the girl was stunned, Chen Xiao walked through the two jade pieces again.

With a slight movement of the divine thought, the problem was solved, two openings were opened one after another, and three high-grade yuan stones rolled down.

"Again...... Solved two more questions?"

The girl swallowed her saliva and froze in place.

This Yuan Stone is too easy to come by!

Even for the noble Dan masters, the speed of making money is not so amazing, right?

At the same time, Chen Xiao walked forward slowly.

The majestic divine thoughts unfolded like a quantum computer, and it was easy to solve one problem after another.

Chen Xiao in the previous life, in addition to being unique in the field of martial arts, the most proficient is Dan Dao.

These problems on the jade bi can be said to be almost unsolvable in Xiheng County and even in Xuanwu Kingdom, but for Chen Xiao, there is no difficulty at all.

As the divine thoughts continue to vibrate, more and more problems are being solved one by one.

One by one, the openings were opened one after another, and the yuan stones, treasures, spiritual materials and other rewards inside...... It almost dazzled Xia Churou's eyes!

"This, this, this ......"

The girl opened her mouth and didn't say a word.

Recalling Chen Xiao's actions of suppressing the magic circle in the medicine garden when she was in the Guhua Medicine Garden, she even began to wonder if Chen Xiao had destroyed the magic circle on the corridor?

If that's the case, the Danshi Guild will be furious!

However, Chen Xiao's speed is really amazing.

In the time that Xia Churou was entangled, he had already passed through the 100-meter corridor and came to the end of the passage!

"Use the lark flower to improve the quality of the forging spirit pill, no matter what means are used to buffer, the final refining pill has no effect?"

When she saw this question, Chen Xiao couldn't help but be stunned, and immediately showed a speechless look: "Such a simple idiot question can still be placed at the end of the side hall?"

In the side hall of the Danshi Guild, the more you go inside, the more difficult and unsolvable the difficulties on the jade bibs on both sides become.

It stands to reason that the last problem, if not the hardest, is not too far off.

However, the belly slander is the belly slander, but when the reward for the answer is a piece of five-colored gold, Chen Xiao still stretched his mind and wrote the answer into the jade.

"The reason for the loss of medicinal effect is very simple, the fundamental principle of forging the elixir is to constantly sharpen the martial artist's Yuan Dan with a variety of trace spirituality, so as to achieve the effect of removing the turnip and preserving the essence. You always think about buffering and buffering, and your spirituality is all buffered by you, so what else can you use to sharpen the Yuan Dan? According to the method I said, calculate the spiritual proportion, and then adjust it to perfection according to your needs......

Writing down the answer to the last difficult question, Yubi slowly lit up, obviously verifying whether the answer was correct or not.

A full minute passed.

The jade bi finally dimmed again, and a dark grid popped out of it, with a five-colored metal inside.

"Sure enough, it's five-colored gold!"

Chen Xiao smiled and nodded, and raised his hand to put it into the Zhentian Temple.

According to the memories of past lives......

The five-colored gold was extremely hard, and as long as it was formed, even the Yuan God Venerable could not cause the slightest damage.

Generally speaking, at the very least, it has to be the Divine Bridge Realm, or even the real Divine Realm, to be able to refine the soldiers with five-colored gold!

However, in addition to the extremely hard characteristic, the five-color gold has no other characteristics, and it is gradually reduced to a chicken rib material.

However, about three hundred years after the previous life, a new secret method was released, which made the cultivation requirements for smelting five-colored gold fall to the level of the Law Phase Realm!

"The five-colored King Kong can be integrated into the Origin God Bead!"

After a little inventory of the harvest, Chen Xiao showed a hint of satisfaction.

Not to mention all kinds of natural treasures, just the high-grade yuan stones, nearly 100 pieces, and at least 1,000 medium-grade yuan stones.

As for the lower grade Yuan Stone?

No one will put down the Pinyuan Stone on this promenade at all!

"Let's go, there's enough money to buy something. ”

Chen Xiao smiled slightly, and walked out, Xia Churou's face was sluggish, and she kept up step by step.

At this moment, the little girl's brain is completely unable to think.

At the gate of the Danshi Guild, the two guards saw Chen Xiao come out, and they immediately showed contempt.

"Boy, you're coming out now, I don't know how many problems you've solved?"

"Come on, how many more are you going to unravel? This kid has only been in and out for a total of ten minutes, and I'm afraid he can't even understand the question, so he can only run away!"

The two sang and harmonized, and laughed in a low voice.

"Idiot. ”

Chen Xiao shook his head speechlessly, didn't bother to pay attention to the two of them, and walked out of the guild's gate.

"You dare to call us idiots, you kid is a kind!" The two of them immediately turned dark, and they whispered with cold faces, "Pretending to be forced, right? Very good, from today onwards, the door of the Danshi Guild will be closed to you forever!"

At this moment, a burst of applause came from the direction of the main hall.

"It's ...... The lecture is over, look, Master Xiao is here!"

I saw a spirited old man coming, with a powerful aura around him, but he did not leave directly, but walked in the direction of the side hall accompanied by a young girl.

"Master, what are you doing here?"

An Siruo asked curiously.

Xiao Chen stroked his beard and smiled, and said lightly: "There is a small habit for teachers, every time I go to a new guild, I will leave a difficult problem, I want to see if there is anyone who can solve it." ”

Hearing this, An Siruo became even more curious: "In a place like Xiheng County, there will be someone here who can solve a problem that you can't solve, Master?"

"We can't say that, there are always some strange people beyond our imagination. ”

The two walked to the end of the corridor, Xiao Chen raised his hand and pressed it to Yubi: "But this time, I don't have hope for the teacher, after all, this problem can't even be solved by the Sanpin Dan Master...... What?!"

But in the next moment, the old man's expression suddenly changed.

"The problem of forging the elixir has been solved?!"

......
