"Boy, you choose! Don't wait for obsolete time!" said the old man Gu Sheng coldly.

"I understand!" Although there was a little more respect in his words, Wu Wei still looked neither humble nor arrogant.

Six bottles of elixir, slowly floating in the air, each with a different color and size of the pill on the mouth of the bottle, each of which seems to have an essence on the surface, the fragrance is attractive, and it is difficult to distinguish between the high and the low.

In the past, the Aoki Dan and Qinglan Dan were just ordinary pills of the lower grades, and there were no Dan lines, compared with them, they were judged from above.

"Boy, this old man is so weird, I can't come forward, it's up to you to choose which one?"

"Senior, no matter which one I choose, can I?"

"Well, my Gu Sheng is a good talker. The corners of Gu Sheng's eyebrows were slightly raised, and he didn't care, but the flesh pain in his eyes was taken into Wu Wei's eyes.

Thinking of the cautious expression of the old man Qianyuanzi when he looked at the Dimu Xuandan in the past, Wu Wei decided that he must get the mid-grade pill from this old man, so that the old man could taste the heartache.

However, this Yin Dan may have been stored in the porcelain vase for a long time, and the surface of the Yin Dan is completely indistinguishable from its true breath. Otherwise, the distinction between the upper and lower grades of the pill can be distinguished at a glance by a discerning person.

When he couldn't tell it, he used his sense.

Wu Wei made up his mind, threw out his divine sense, and carefully examined the six pills.

According to the old man's codex, the easiest way to distinguish the pill is not only to look at the color, but also to observe the face, break the shape, probe the qi, and the four steps of the spirit.

If there are no special circumstances, look at it roughly, the quality of a pill can be glimpsed from its roundness and fullness, and the degree of SCP release, but the pill in front of you has been infiltrated in the medicine bottle for too long, and most of the external essence has converged, which is difficult to identify by this method;

To observe the face is to carefully observe its color, whether it is transparent and bright under the light, whether it is dull and dull, and the number of impurities and spots on the surface of its elixir;

The perfection of the elixir is not the bigger the better, but it is not the smaller the better, but it is better to compress the medicinal properties to the best size for human consumption;

Detecting qi is to use the divine sense to probe the imprint or medicinal gas around the elixir, the thicker the medicinal properties, the stronger the imprinted power will be, under normal circumstances, it is enough to penetrate with the divine sense of the spiritual power, but there are special cases, that is a lot of elixirs, just like the iceberg on the ocean,

The medicinal properties are inflexible but restrained, so that the preliminary judgment of looking at the color is easy for the old horse to stumble;

Shen Xuan is the most accurate way, that is, to use divine consciousness to infiltrate into the pill, and trace the source through the internal structure of the pill, so as to judge the properties of the medicine, but this step is by no means easy for Wu Wei, who is not even a novice, to do.

Therefore, Wu Wei can only use the other three methods except for Shen Xuan.

Wu Wei walked forward, and his divine sense slowly spread out, not missing a single cent.

Seeing that the action was calm, the corners of Gu Sheng's eyebrows also showed a hint of solemnity: "Nomu old man, you taught quite well!"

"Hehe, that's ...... After all, I taught it. ”

Wu Wei, who was on the side, rolled his eyes and didn't pay attention to the latter's cheeks, you know, these things are not old man, but he has never taught him, they are all from him begging for books in vain.

Listening to the nagging of the two on the side, Wu Wei simply turned a deaf ear, so as not to disturb his mind.

Cha Yan, Wu Wei excluded one, which should be of the highest grade on the ground level, and there are too many impurities;

broken, Wu Wei excluded two more, one too big and one too small;

As for the remaining three, it is difficult to tell.

Do you want to probe your air?

The divine sense is detailed, but it is quite difficult, especially the two pills, which are similar in appearance and difficult to distinguish. Wu Wei's eyes were slightly closed, and his consciousness pondered carefully.

One of them, the color is dark, but the medicinal properties are stronger than the other, as if there is a broken body and overflowing, if judged by the medicinal properties, it seems that it should be the middle grade of the heavenly rank.

However, the other one, although its medicinal properties did not fully overflow, but it had a sign of restraint, but if it did not use the method of divine selection, it was actually difficult to see through.

As for the last one, it seems to be extremely ordinary, but when I think about it, it is more and more incomprehensible, and the divine sense is swept away, like a stone sinking into the sea, without warning, if you just look at the medicinal properties, at first glance it is even inferior to the top grade of the ground, but it is precisely because of this strangeness that Wu Wei pays more attention to it.

These three pills, even if you get any of them, they are actually not a loss, but Wu Wei is gambling and must find out the heaven-rank mid-grade pill.

This kid seems to have encountered a difficulty, seeing that Wu Wei's eyes have been locked on the last three pills, but he has been slow to make a judgment.

It was the old-fashioned Gu Sheng, and the corners of his mouth were also smug smiles.

"Old head, your method is weird, if you don't know the magic method, I'm afraid even I won't be able to see it. The old man was dissatisfied.

"Hehe, okay, others are not allowed to intervene. Gu Sheng made a color at Bumu. "Young people, you should suffer some setbacks, lest you not know the height of the sky!"

This ancient predecessor borrowed a donkey on the slope.

Wu Wei turned a deaf ear and thought a little, it was difficult for his divine sense to get his way, so what should he do?

Wu Wei's eyes suddenly jumped, by the way, look at Danwen.

The more advanced the Yin Dan, the more complex the Dan pattern is, but my knowledge of the seal is too superficial, and I don't know how much I can use.

Whatever, let's talk about it.

Thinking of this, Wu Wei didn't care about its Yin Dan appearance, but observed its Dan pattern.

"Hehe, this kid wants to find another way and start from Danwen, but it's a pity that he hasn't even seen these grammars and patterns. Gu Sheng's eyes flashed with a hint of approval, but then he shook his head frequently.

Wu Wei sat cross-legged, sitting under the six pills, his eyes slightly closed, contemplating and contemplating.

Grammar?

Print?

As Gu Sheng said, with his three-legged cat kung fu, it is simply delusional.

But he still has one trick, which has failed and failed many times.

In the world of SCP, Wu Wei and the villain sat and looked at each other, their hands and hands kept fighting, the eyes between the two were intertwined, their eyes were as clear as a stream, and some nameless seals rose to the sky, lingering and spreading around the two.

This was the first time he had invoked this eight-character proverb on his own initiative after mastering the crematorium fire array.

The eight-character proverb, like a gilded big character, slowly emerged from somewhere in the seal, Wu Wei suddenly opened his eyes, and his divine sense burst out, although he still couldn't understand those unfamiliar seals, but the law in it made him think.

Gu Sheng looked at his expression, and he also understood something, this kid has some ability!!

"Look, I'll just say this kid, okay!" Old Man Bumu whispered at Gu Sheng, "His grammar talent is probably only a finger behind yours." ”

"Hmph, it's not over yet, don't put a gloss on his face. Gu Sheng turned his eyes to look at the young man again, this kid really made him feel no

Little interest, just when he was exploring his world of SCP, it was ......

A moment later, on Wu Wei's forehead, sweating profusely, his face was pale, his breathing was short, and he was undulating.

Gu Sheng's brows furrowed, it seemed that this kid couldn't control it freely, he sighed slightly, and was about to make a move.

The old man stopped him: "Wait!"

"No, old man, you know very well about the backlash of your divine sense, how can you allow him to mess around!" Gu Sheng was a little unhappy, watching the sweat droplets on Wu Wei's head fall like rain, but he was a little worried in his heart.

"Wait, isn't this with you? With you Gu Sheng making a move, even if it lasts until the last moment, it will be too late, and you have to give the young man some chances! This kid's temperament, I know, he will be measured. The old man blinked his eyes and comforted Gu Sheng beside him.

"Zheng" The air around this trembled suddenly, and the appearance of the six pills was actually full of colorful phantom colors, as if they were in the same way, and their colors were clear at a glance.

This kid actually resonated with the print!!

"Look, I'm not wrong, just keep your eyes open and wait! ”

It's just that having said that, Wu Wei at this moment is indeed in dire straits, and the eight-character proverb has been fine since the beginning of the slow lingering around his body, but when he resonated with the Yin Dan from the outside world, the whole person was like sitting on a volcanic crater, with magma surging under his body, and the scorching sun above his head.

Inside this illusory body, it was as if the blood was about to boil, and the painful expression was overflowing, and he wanted to stop, but at this moment, the eight-character proverb in his body was faintly out of control.

"Gu Tou, let's make a move! It seems that we have reached the limit!" After another moment, the old man turned his head and looked at Gu Sheng.

"Hmph, you don't know how many people you have to kill with this teaching!" Gu Sheng's figure floated, like a breeze, and with a wave of his palm, he transformed into a palm the size of a pu fan, and two crystalline seals poured directly into Wu Wei's Baihui Tianchi Second Acupoint.

The second power was like cool ice water, which made Wu Wei's body cool suddenly, and the burning heat in his whole body quickly subsided.

"Remember this mantra, and if you encounter this situation next time, recite it a hundred times!"

In the world of SCP, Wu Wei suddenly felt that there was a majestic god on his head, and a melodious mantra was constantly used towards him from all directions, and its sound was like a bell, omnipresent, like a decree between heaven and earth descending into the world, deep into his divine consciousness, and could not be forgotten.

"Remember, this is the wind and the clear seal, the breeze is coming, and the consciousness is difficult to prosper, which is the method of excessive containment of the operation of the seal and the seal. "Far away, the world of SCP is peaceful.

"Thank you, senior!" Wu Wei's eyes widened sharply, and he gave a salute to Gu Sheng, he could clear the grievances, and this style was clear and clear, which was a great favor.

"It's okay, after all, this matter started with me!" Gu Sheng shook his head and avoided Wu Wei's salute.

"Let's choose the medicine!"

In the tone, there was a little more appreciation and a little less arrogance.

Wu Wei raised his head and looked at the six pills in the air, their expressions were shining, they were all extraordinary, and the difference in their expressions was clear at a glance.

He pondered for a moment, stretched out his hand, but stopped slightly on the most radiant Yin Dan, and instead took a slightly dim Heavenly Rank Lower Grade Pill next to him.

"Alas, boy Wu Wei, how did you choose this?"

"Hehe, senior, although my elixir is only a low-grade pill, and that pill is a mid-grade pill, but for me, it is enough, too much, the best may not be the most suitable for me. Wu Wei took the elixir and bowed slightly to Old Man Gu Sheng to express his gratitude.

"Not arrogant or impatient, knowing how to make trade-offs, this kid is indeed much better than me before. Old man Gu Sheng glanced at Wu Wei.

Both of them are happy, but only the old man Bumu is left, sulking on that side, you know, he has the idea of the Heavenly Rank Yin Dan, you take it first, if you don't want it, I can exchange it with you for something else.
