Two hours later, Lin Xuan returned to his cave mansion.

Recalling that when he was close to the mountain gate, a few wisps of divine consciousness lingered around him, and Lin Xuan was amused.

Needless to say, these are all masters of the major potentials, and their cultivation should have reached the realm of the Ning Dan stage.

Presumably they thought they wouldn't find out, who knew that their divine sense was far superior to that of fellow cultivators, but they just pretended not to know!

Although they didn't see it with their own eyes, it was not difficult for them to guess one or two of their feelings, and they sent so many disciples with advanced cultivation to follow them, but they didn't hear from them one by one.

However, the status of the Elixir Mountain was there, and unless it was confirmed that the matter of the Heavenly Dust Pill was indeed true, they would not dare to tear their faces, and they could only be secretly depressed.

Finally got a bad breath!

Of course, Lin Xuan will not be rash, the rest of the troubles have nothing to do with him, and the elders in his own sect are worried, but judging from the current situation, both the righteous and the demon are very restrained, and they don't believe in the rumors very much, so the reason why they have sent disciples one after another is mainly just in case.

In other words, as long as there are no accidents, there should be no problem for Elixir Mountain to survive this crisis safely.

Next, I have to work hard to improve the realm of cultivation!

Lin Xuan opened the Extreme Yin Evil Spirit Array. Then I came to the alchemy room.

He wants to use the shortest time to prepare the Seven Heart Pills. It is convenient to practice the "yin and yang formula".

Although nominally the young master of the elixir mountain. But Lin Xuandi's alchemy was a mess. Of course. He doesn't care whether the alchemy is successful or not. Anyway, there is a blue sea of stars that can purify the discarded land elixir.

It only took one day. Lin Xuan got nine "Seven Heart Pills". with the marrow cleansing pill. Tsukidan and other power-enhancing elixirs are different. The Seven Heart Pill can only be taken one at a time. Not only is there no benefit to taking multiple doses. Instead, it will have the opposite effect.

Lin Xuan calculated in his heart. Nine capsules. There should be no problem in supporting yourself to practice yin and yang.

Take out the jade tube Jane. Read the Yin and Yang recipe engraved in it a few more times. Every word and every sentence is carefully considered. Be sure that there is no fallacy in your own understanding. Then Lin Xuan meditated and practiced qi again. Adjust your mind and body to the best condition.

Practicing this secret method can be said to be a desperate gamble, and it has succeeded, and the sea and the sky are wide. Not only will his own strength immediately increase, but also being able to cultivate the Nine Heavens Xuangong and the Ghost Dao Secret Technique at the same time will also be of great benefit to his future cultivation career......

As for failure. Well, the soul is gone, and there is no return.

This determination was not easy to make, but in the end, Lin Xuan still chose to face the difficulties!

I want to have it. You must pay first, and it is worth taking some risks to learn such an anti-heaven exercise, and cultivating the truth is already full of thorns and fear. I shouldn't have embarked on this path in the first place!

Not to mention anything else, Lin Xuan still has some confidence in his perseverance.

Sitting cross-legged, Lin Xuan took a fiery "Seven Heart Pill".

This elixir is made of seven kinds of highly toxic substances, but after the medicinal power is neutralized, it has the effect of concentrating and calming the mind, which can protect the mind and keep the clarity of the spiritual platform in various disturbing pains.

The medicinal power dissolved, and a cool cloud rose from the dantian. And quickly flow through the meridians of the whole body.

Lin Xuan didn't dare to slack off. Start cultivating according to the content described in the Yin and Yang formula.

The process is extremely difficult, and the key is when the Yin and Yang spiritual power is first transformed. The unspeakable pain, originally, Lin Xuan thought that the description in the exercise was exaggerated, after all, he had also been on the Heart Refining Road before, and the sword mountain and the sea of fire were nothing......

But now it seems that there is nothing to be proud of at all, compared to the pain of practicing yin and yang, the path of heart refining is just pediatrics.

What's more, at that time, I couldn't stand it, and I could still run out of the river and rest for a while, but now, I have to grit my teeth and bear it until the refining stops, and this pain will last for at least a week.

Although the pain was greater than expected, but fortunately, Lin Xuan's perseverance was extremely tenacious, coupled with sufficient preparation, after taking the Seven Heart Pill, even if it was painful, his mind was never confused, he gritted his teeth and endured it.

While Lin Xuan was cultivating desperately, Lin Yue'er was not idle, the little yin soul was now at the peak of the spirit period, and if he went further, he could build a successful foundation.

Unlike the master's garbage qualifications, Yue'er is a real pure yin body, plus she is a yin ghost, and it is easier to practice ghost cultivation techniques than human monks.

There is almost no problem of failure in foundation building.

At this time, in another stone room, Lin Yue'er was also sitting cross-legged, but she was floating in mid-air.

Although it has not yet reached the point of condensing entities, Xiao Yue'er's soul energy is very stable at this time, as long as she doesn't touch it with her hands, she can hardly see that she is a ghost, just like a beautiful girl of a human being.

Lin Xuan was not worried about Yue'er, on the contrary, now that he had reached the most dangerous moment, it was useless to endure the pain, he had to practice according to the records of the Yin and Yang Formula, and he could not make the slightest mistake.

It was not so much a practice as it was a torture that almost drove him crazy.

For a cultivator, a week is really not worth mentioning, but for Lin Xuan, every second is more difficult than a year.

Several times he was on the verge of collapse, but when it was too late, he always persevered.

A week has finally passed.

"Whew!"

Lin Xuan let out a long sigh, and then collapsed to the ground as if he had lost his support.

I don't want to move a finger.

The whole body was sweating profusely, as if it had been fished out of water.

It was extremely embarrassing, even when he experienced life and death battles before, he didn't have such a hard time, thinking about the past seven days and days, Lin Xuan's scalp was numb for a while, and he was afraid!

Fortunately, although the process was painful, the result was finally perfect, and the yin and yang formula was refined!
