Tuoba Long removed the soundproof barrier in the room, first probed to see if there was anyone outside, and then held his breath and left the room.

Not long after Tuoba Long left, Zhang Yifeng's shadow also quietly followed.

This Tuoba Dragon is a source, and a lot of information should be found from him.

Zhang Yifeng is now trying to figure out what this war is all about.

Tuoba Long left the house and quickly returned to the ninth floor.

After Zhang Yifeng came to the ninth floor, he was more cautious, he knew that the higher the number of layers in the castle, the more identity and status the people who lived there, and this ninth floor was probably where Tuoba Yu lived.

Zhang Yifeng's shadow, as soon as he reached the ninth floor, felt a powerful spiritual fluctuation.

This mental fluctuation is likely to come from Tuoba Yu.

At that moment, Zhang Yifeng did not hesitate and hurriedly withdrew his shadow.

On the ninth floor, he can't go yet! At least the current cultivation can't go. Tuoba Yu has a high probability of being a strong man in the Yuanhua period!

With this kind of cultivation, I am afraid that there are not many opponents in the cultivation realm. Even if the main one has exhausted all its resources, it can only cultivate one or two masters who may step into the metamorphosis period.

Zhang Yifeng didn't dare to go deeper, once he was discovered, although he would not die, but his soul would be damaged, but it would inevitably startle the snake, and it would be extremely difficult to find out the news in the future.

In the room, Zhang Yifeng opened his eyes, and it seemed that he wanted to find out the news, and he had to go to the woman's room tomorrow night. I don't know if Tuoba Long will have a tryst with the woman, according to the logic of normal people, Tuoba Long will definitely go again, after all, once these things start, if they don't linger for ten days and a half months, they will not lose their freshness.

Zhang Yifeng plans to go to the woman's room every night to keep an eye on the sentry.

Shaking his head, Zhang Yifeng stood up and arranged a hidden formation in the room. Then he entered the formation and sacrificed the Dan furnace.

Since he is now cultivating, he doesn't dare to go to the ninth layer, so let's start refining the golden pill and continue to improve his cultivation.

Zhang Yifeng asked for some of Jindan's materials from Zhengmen, and asked Su Zhirou to take some from Tuoba's house.

Although the number is not much, according to Zhang Yifeng's Cheng Dan amount, it should be no problem to improve the early stage of cultivation to three or four layers. Zhang Yifeng's huge consumption is reflected in the later stage of every great realm, especially the eighth and ninth layers. The huge consumption made him very painful.

After sacrificing the Dan Furnace, Zhang Yifeng's expression became serious, because the Jin Dan is not so easy to refine!

For cultivators, the Jindan period is a watershed, so the pills that cultivators need in the Jindan period are naturally not something that ordinary Dan masters can refine.

Many Dan masters in the Lingyue Continent are stuck at this threshold, and they can't refine the pills that Jindan stage cultivators need in their lifetime. Because this level of elixir not only requires more subtle alchemy techniques and fire control techniques, but also requires the Dan Master to have heaven and earth spiritual fire! Even if he has a fire attribute aura, he may not be able to succeed, unless this Dan Master's cultivation itself is in the Jindan stage, and only the fire attribute aura of a Jindan stage cultivator is qualified to melt the medicinal materials of the Jindan stage.

More important than that is the consciousness is the consciousness.

If the divine consciousness did not increase, it would be very difficult to refine the elixir of the Golden Pill Stage.

Although Zhang Yifeng has absolute confidence in himself, he must also take it seriously, after all, he does not have much raw materials to consume.

There are not many main raw materials needed to refine the Golden Pill, there are nine in total, but these nine elixirs are all precious medicinal materials, which may be common in the Lingyue Continent, but they are relatively rare in the cultivation realm.

Zhang Yifeng took out nine main medicinal herbs, one by one, and threw them into the Dan furnace one after another.

Subsequently, Zhang Yifeng cast the Blue Moon Fire and began to melt the medicinal herbs.

Originally, he planned to cast the Nether Ghost Fire, but after thinking about it, he gave up, after all, this is the base camp of the Tuoba family. If the Netherfire is discovered, it will be a dead end.

Although Blue Moon Fire was slower, he wasn't in a hurry anyway.

Soon, a night passed.

Zhang Yifeng finally cast the Blue Moon Fire to melt all nine medicinal herbs.

The process of melting is also the process of removing impurities.

At this time, nine drops of solution were suspended in the Dan furnace, like nine stars, rotating with each other.

Next, it's time for the process of integration.

"Melt!"

With a soft drink, Zhang Yifeng released the power of his divine consciousness to the maximum, enveloping the nine drops of solution, causing the nine drops of solution to merge with each other.

Nine drops of the solution approached quickly, touching each other almost simultaneously, then squeezed, compressed, and fused!

This process may seem simple, but it is actually very complex and not sloppy at all.

The fusion process of these nine drops of solution must be uniform in every part, if there is more than a certain solution in one place, when condensing Dan, it can cause this part of the solution to directly become waste residue, and the final number of finished Dan is definitely not much.

If the fusion of the whole solution is not uniform! The result is obvious, in the end, only a pile of waste residue will appear, declaring the alchemy a failure.

After fusion, you can condense Dan.

Time passed, and Zhang Yifeng's face turned a little pale, this was because his divine sense was consumed too much. After all, before alchemy, he also performed the Shadow Exploration Technique.

Without hesitation, Zhang Yifeng took a Huishen Pill, recovered some of his divine sense, and then continued to fuse the solution.

An hour, two hours......

In the Dan furnace, the nine drops of solution were already completely compatible, and the solution of the nine colors formed a huge mass of solution, which rotated slowly in the Dan furnace, like a ball of nine colors.

Three hours, four hours......

The color of the nine-color ball is gradually decreasing, and it has become an eight-color ......

Seven hours...... Eight hours......

The nine-colored ball has become the six-colored ball.

This is the process of fusion, when the solution has only one color of uniform divisions, it can be considered completely compatible!

And this last color must be gold. If gold is mixed with any other color, it fails. It can only show that when it first melted, the temperature of the flame was not well controlled, and all the impurities were not removed.

Time passes, from the rising sun to the sunset.

In the Dan furnace, the solution has changed from the first nine colors to two colors.

One white, one black, without the slightest gold, if it was the first time to refine the golden pill, he would definitely think that he had failed. After all, when I practiced at this time, I didn't even have a little gold, what is it if I don't fail?

But Zhang Yifeng is not a beginner, he naturally understands better than anyone else that he has not failed.

Now is the most important moment for refining Jindan.

It is necessary to make the two colors, black and white, completely compatible with each other, to be considered successful.

These two colors are opposed to each other, they are like cats and mice, natural enemies. As soon as one side approaches, the other party instinctively resists.

As long as one is not careful, Zhang Yifeng's hard work this day will be in vain. At this time, the role of the divine consciousness is reflected, if you want to refine the golden pill, if you want to fuse these two colors, you must forcibly fuse the two together with lightning speed, so that they have no time to resist, even if they resist, under the powerful divine consciousness, they will not be able to resist!
