"Thank you, senior."

Now is not the time to watch the jade slip, Qin Su put the jade slip away, and thanked the old guy for owing it.

"Don't thank me, you saved the old boy's life, it's an equivalent deal." The old guy waved his hand and said impatiently, "Since you have already obtained it, let's go." ”

Qin Su was stunned.

Ning Chen also felt a little funny, this old guy looked like he was cutting meat, but in the end, he still gave himself the body refining method, and now he has issued an eviction order, this is the third time, right?

"Senior, as I said below, the body refining method can be exchanged for items."

Ning Chen took out a demon pill from himself, put it on the old guy's table, and said with a smile: "This half-step demon pill of the king realm can be regarded as a thank you gift, I see that you lack a formation core in this formation, and you can just use this demon pill to make up for it." ”

This demon pill was taken out of the body of the half-step King Realm demon clan that was killed in the forest after coming down from the Dragon and Tiger Gate.

For a long time, this demon pill had no effect, and if it weren't for the reminder of the painting at that time, Ning Chen didn't know that there would be a demon pill in the demon clan's body, and now it's a little funny to think about it.

After entering the thatched house, Ning Chen observed the formation carved on the table.

Those formations, naturally, are just models, just deductions.

Although Ning Chen didn't know the formation, he had been with Huaxin for a long time, and he was somewhat familiar with it, and he knew a little bit about it, and he could see at a glance that the formation lacked a formation core.

And the items that can be used as the core of the formation must have sufficient energy, so that the energy in it can be continuously replenished into the formation, so that it can always play a role.

This is also the reason why some formations have existed for a long time and have failed, just because the core of the formation has no energy supply.

And within the demon pill, there is no doubt that there is a huge amount of energy, and the essence of the demon clan is in the demon pill, which is very suitable for being used as a formation core.

The demon pill was quietly placed on the table, exuding faint fluctuations, and around the demon pill, there were circles of ripples, rippling.

"Sure enough, it's a half-step king realm demon pill!"

The old guy wanted to drive Ning Chen and the others away directly, but after seeing this demon pill, his eyes were directly locked on it, and he couldn't move a single bit.

His formation lacks a formation core.

After swallowing a deep mouthful of saliva, the old guy slowly closed his eyes and said: "As the so-called reactive power is not punished, you saved the old boy's life, and I exchanged it for a body refining exercise, which is an equivalent transaction, but you are humiliating me by taking out this demon pill now?" Look down on me? Think I can look at this demon pill? ”

Ning Chen suddenly felt funny, obviously he wanted it very much, but he didn't want it, this old guy's temper was really weird, but I have to say that it was a little cute.

"Senior, if you feel that it is useless, you can exchange it for other items."

Huaxin covered his mouth and chuckled: "I can see that this formation of the predecessors is the prototype of the four-grade formation, only the core of the formation is missing, if the predecessors use this demon pill as the formation core and successfully stimulate the prototype of the four-grade formation, then, the attainments above the formation will also enter the realm of the four products, this is a big opportunity, the predecessors are really sure not to?" ”

The old guy's eyes lit up, he really needed this demon pill.

"You little girl, you have some eyesight, you can see the grade of the prototype of this formation, you must also be from an extraordinary background, right?"

The old guy glanced at Huaxin with a meaningful smile, and after a while, he retracted his gaze and said, "What you said also makes some sense, so I'll exchange other items with you for this demon pill." ”

As he spoke, the old fellow's feet stomped lightly on the ground.

"Squeak ......"

A voice sounded, and above the ground, a depression suddenly appeared, but it was an underground passage.

"Whoosh!"

The old guy jumped into the passage.

Ning Chen and the others were stunned for a while, this old guy was still in his room, and there were still some hidden passages and the like, which was a bit too careful.

"Don't be surprised, don't be surprised, my old friend, before he came into contact with pills and formations, he was obsessed with all kinds of organs for a period of time, and his attainments in the organs were also quite amazing." Song Yucheng explained.

In this place today, Song Yucheng just explained to Ning Chen and the others, and it was quite a waste of saliva.

"Sure enough, it's a strange man, a weirdo." Ning Chen shook his head and said in amazement.

Ordinary people have made achievements in one place, which is already quite good, but this old guy has good attainments in all aspects.

This kind of insight, such vast knowledge, is really embarrassing.

Ning Chen suddenly felt that this old guy's age of more than one hundred and thirty years was really not a long time for him, and it took twenty years to study every interest, I am afraid it would not be enough.

Not long after, the figure of the old guy jumped up from the underpass.

In his hand, he had a book in his hand.

The cover of the book, presented in purple, exudes a demonic atmosphere, just looking at it, people can't help but immerse themselves in it.

Five Elements Returning to the Element!

Seeing this book, Ning Chen's heart jumped suddenly, his eyelids trembled, and then he lowered his head slightly, and the corners of his eyes twitched a few times before he regained his composure, and when he raised his head again, he was already back to the same as before.

"Well, this is also an exercise, for me, it's useless, give it to you, as a demon pill in exchange."

The old guy flicked the cover of the book, and with a wave of his hand, he threw the book towards Ning Chen.

Ning Chen hurriedly stretched out his hand and took the book in his hand, shocked in his heart, he never imagined that he would get a Five Elements Returning Technique here.

Moreover, it was obtained in exchange for the demon pill.

Compared with the Five Elements Returning Technique, the mere demon pill is really too shabby.

"This old guy may not know the power and mystery of this Five Elements Returning Technique, and gave it to me as an ordinary exercise."

Ning Chen secretly said in his heart, on the surface, he quietly put away the book, and did not let Huaxin and the others see the surface of the book, otherwise Huaxin and the others would definitely be able to recognize it at a glance, this is the Five Elements Returning Technique.

If the power of the Five Elements Returning Technique was exposed, and the old guy wanted to take it back, then Ning Chen would definitely be extremely distressed.

In the face of the temptation of the Five Elements Returning to the Yuan Technique, it would be false to say that Ning Chen was not moved.

Therefore, the more natural it can become, the more natural it is.

After putting away the Five Elements Returning Technique, Ning Chen bent down slightly at the old guy and arched his hand: "Thank you seniors, since the seniors insisted on exchanging items for demon pills, they would be disrespectful." ”

Speaking of this, Ning Chen nodded at it, and said in a joking tone: "In the inferior people, this is the departure, the seniors of the province feel that we are nagging, and they will give the fourth order to expel the guests." ”
