The three of them looked at each other for a moment, and a moment later, a complete charter was placed on the table.

Jiang Xin taught a certain disciple in the Tang Sect the detoxification method in exchange for the secret of the Tang Sect - the cultivation method of Dan Swallowing, but all the consequences caused by cultivation had nothing to do with the Tang Sect.

The Tang Sect could circulate the spells exchanged with Jiang Xin internally, but it must not circulate to the outside world in any way. In the same way, Jiang Xin can spread the Dan Devour to a certain extent, but it is limited to a single Inhuman, and must not be handed over to any other Inhuman organization.

As for restricting Jiang Xin's idea of not spreading the 'method of detoxification' of Dan Yan... Several people did not mention it, apparently understanding that this was a not very reasonable and realistic thing.

The essence of the exchange between the two is the mutual exchange of knowledge, and the Tang Sect has no legitimate reason to restrict Jiang Xin from handing over his own 'knowledge' to others, but only to restrict Jiang Xin from spreading his own Dan devour.

The conditions for cultivating this thing are indeed difficult, but once it spreads, it is difficult to guarantee that no one will practice to do evil in all directions, so it must be restricted from the beginning.

As for the method of detoxification, Jiang Xin didn't want to be able to solve the Dan devouring he had learned to some extent one day, which would be too cost-effective.

In fact, there are many questions in the charter set by Jiang Xin and them, such as whether the black water can unlock the poison of Dan Devouring...

But in fact, Jiang Xin didn't plan to exchange the black water that could dissolve the purple flame for Dan Yu, but planned to play a trick of empty gloves white wolf.

He could first get the cultivation method of Dan Devour from Tang Sect, and then hand over the reversed Dan Devouring and Detoxification Method to Tang Sect, and all he needed to pay was a little Yuan Qi.

Although Dan Yu is poison in the Tang Sect, it is different from ordinary Qi poison in that Dan Yu does not need ingredients from other drugs outside as a medicine guide.

The reason why the word 'external medicine' appears in the cultivation of Dan Devour is that one is to practice Qi poison first, and the other is to enhance the body's patience, so as to increase the success rate of cultivating Dan Devour, and at the same time relieve some pain when people die.

But if there is really a perfect fit, even if you don't use external drugs to hone your body, it's okay. Foreign medicines are all made out by people out of desperation and in order to increase the success rate, so that some people who are only one step away from being qualified to cultivate.

But with Jiang Xin's physique, do you need these things?

Obviously, no.

Not long after, after all the disputes were resolved, Jiang Xin and his party summoned a famous oath master to make an oath. Then he walked to the Tang mound in the back mountain.

That's right, after thinking about it carefully, Tang Miaoxing and the others finally decided to go to Tang Mound to complete all the exchanges, for many reasons, but the most important thing is that for safety and secrecy, those disciples outside are not yet able to see Dan Yu.

......

"This is Karazuka?" After turning back and forth in the stone formation several times, the canyon where Tang Mound was located finally appeared in Jiang Xin's eyes, and after stepping through the canyon, there was a huge circular clearing inside, and there were holes on the mountain at the edge of the clearing, and there were people on both sides.

"Alright." Taking Jiang Xin all the way to a huge stone tablet in the middle of the Tang Tomb, Tang Miaoxing finally stopped and pointed to the stone tablet in front of him: "What is recorded on it is the top secret of my Tang Sect - Dan Swallow." ”

"This stele..."

Jiang Xin walked in a little, and then found that 1 on the stone tablet was not only a huge Dan Yu diagram depicted by vermilion, but also a small font carved on the blank part outside the Dan Yu map.

These fonts are long or short, and they are arranged in a neat and orderly manner. Obviously, everything recorded on this stele should be related to Danyu: "What are these words?"

"Foreign medicines, precautions, and Xingqi Wenjie are all related to Dan Swallow." Tang Miaoxing looked at the huge stone tablet in front of him, and the expression in his eyes couldn't help but be low.

"That's right." Jiang Xin searched for it on the stone tablet, and after a while, he found what he needed most - Xingqi Wenjie.

The Dan Diagram is a graphic that reveals the route of the person's internal Qi breath, while the text explanation is a detailed description of the Dantian, acupoints, meridians and their sequence when performing the Qi.

The reason why it is necessary to have both is to facilitate some people who may be defective in other places, and at the same time, it is also convenient to preserve.

At this time, this weight is actually convenient for Jiang Xin.

There are 720 acupuncture points in the human body, Jiang Xin has already memorized them in his mind, and at this time, the two Xingqi methods are in front of him, Jiang Xin just moves in the year, and controls the acupoint assessment, so that Yuan Qi flows up with the running line of the Dan Devour.

The next moment when Jiang Xin was doing Qi, Tang Miaoxing immediately discovered Jiang Xin's movements, and looked at Jiang Xin, who had completely completed his Qi practice almost instantly and began to enter the process of practicing Qi, and he didn't feel a trace of surprise and worry in his eyes.

The surprise was that Jiang Xin's speed was fast, and the worry was because practicing poison was not an ordinary method, so he must not be strong.

But once again, things did not happen to a few people.

Jiang Xin hadn't fully understood Yuan Qi's magic until now, and whenever he thought that it was already the limit, the next moment he could discover a new use again, just like at this moment.

The middle dantian qi breath is self-contained, the upper and lower dantian are integrated, and at the same time, a closed qi road is formed on the left side of the lower dantian, and between the flow of the yuan qi, in just a few minutes, a wisp of unique qi was refined by jiang xin in the body.

But in the next moment, the Qi that had been refined devoured Jiang Xin's body at an even more violent speed.

With the dantian as the birthplace, the formless and colorless danqi instantly broke free from the shackles of Yuan Qi and was about to spread out along the meridians, and at the same time, a tingling pain instantly echoed in Jiang Xin's body.

"Oops!" Jiang Xin's heart was awe-struck, and he suddenly understood that he should have failed, and Dan Yan broke free from the shackles and began to eat his body.

"Reversal!" With a soft roar in his heart, Yuan Qi, who had been retreating steadily, instantly surged like a frenzy, and between the opening and closing of hundreds of acupoints, Yuan Qi's form changed instantly, turning into an incomparably turbid pool of black water and rushing over, completely suppressing Dan Yu in just one fell swoop.

And after the Black Water Hour, the meridians that were originally corroded by Dan Devour were also repaired again, but they looked a little fragile, and I am afraid it will take some time to fully recover.

Outside, seeing that the Qi breath on Jiang Xin's body was torn, Tang Miaoxing's heart suddenly became one, and then he found that the crack was completely suppressed, and Jiang Xin also opened his eyes.

Taking a deep breath, Jiang Xin's heartbeat gradually calmed down, and he looked at a few people when the Qi breath in his body was completely calmed down: "Good luck." ”

With the solution to the poison of Dan Devouring, the rest of the matter was much simpler for Jiang Xin.

Even if you can't master Dan Swallow, you still have the capital to use this means.
