Heart-Eroding Grass is very poisonous and has a great corrosive effect on other elixirs.

Chu Heng had to be cautious, for fear that the slightest negligence would cause the elixir that had been refined before to be scrapped.

This process was quite mind-consuming, but I don't know if it was because the previous exercises had achieved results, or if Chu Heng was lucky, and there were no accidents with the fusion of the Heart Erosion Grass.

"Whew!"

The emerald green droplets eventually transformed into dark green, exuding a faint fragrance that was completely poison-free.

Chu Heng let out a sigh, took a pill of spirit pill to recover slightly, and then began to refine and fuse again.

Time flies.

Half a day later, Chu Heng had already fused more than ten kinds of elixirs, and now there was only a blue-gray paste left in the ding.

It can be said that at this point, the refining of ecstasy incense has basically been successful.

The color of the paste-like object in front of you is exactly the same as the half-cut ecstasy incense, which shows that as long as the paste-like object is solidified, the finished product of the ecstasy incense can be obtained.

Seeing such results, Chu Heng's eyes flashed slightly, and a touch of joy couldn't help but appear on his face.

He was calm, and although he had reached the last step, he still had to be cautious, otherwise he would still make mistakes.

At this moment, I saw Chu Heng pinching out a seal with both hands, and the fire of the leylines below suddenly rose a few points, and the temperature suddenly rose, burning this alchemy room to a scorching heat.

"Condensation!"

Chu Heng's face was solemn, he controlled the flames, calcined the paste-like object in the ding, and let it gradually condense into a slender incense.

After taking shape, he closed his eyes, his face was unwavering, and he let the ecstasy incense float in the flames, burning constantly.

After another two hours, Chu Heng suddenly opened his eyes, and with a wave of his robe, the lid was lifted, and the fire of the leylines below was also extinguished and fell silent.

A peculiar fragrance wafted from inside the ding.

Chu Heng grabbed it with his right hand, and a suction force gushed out, sucking out all the ecstasy incense in the ding, and it just fell into a long jade box that appeared in his hand at some point.

Chu Heng carefully looked at the ecstasy incense, and even came close to smell it.

Then, he took out the remaining half of the ecstasy incense for comparison, and found that the ecstasy incense that he regarded as a treasure before was more than a star and a half worse than the ecstasy incense he had just refined.

"It's worthy of being a good thing that has been improved by an alchemist!" Chu Heng thought of surprise in his heart, and at the same time, he could also be sure that what was being refined in front of him was the Ecstasy Incense.

It can't be blamed for his hesitation, after all, in the true sense, this is his first refining, and he has succeeded like this, and he has never experienced even a single failure, and few people believe it when he says it.

Even those true alchemists are afraid that they can't guarantee that they will be able to do this.

Next, Chu Heng was full of energy, and after meditating and resting, he started refining again, after all, he still had a few elixirs in his hand, which was enough to refine four or five furnaces.

In the end, Chu Heng spent a day and a night refining the remaining elixirs into this improved version of Ecstasy Incense, a total of five furnaces, but one of them failed, which made him feel a little painful.

At the same time, the rare spirit flower of the Phantom Soul Flower was also consumed, and he had to stop.

"A total of one hundred and eight improved Ecstasy Incense has been refined, which is enough to use for a long time. ”

Chu Heng's eyes flickered, and he decided to do a big job.

He set his sights on Yunmeng Razor!

The trip to the secret realm made him taste the sweetness, and at the same time, he also felt the crisis, and Chu Heng was eager to improve his strength.

Especially when the head of the sect suddenly promoted him to a core disciple, he didn't have to think about it, and he knew that there must be many people who were red-eyed.

Chu Heng had understood that the core disciples should at least have innate realm cultivation, and he was only now transformed into the ninth heaven.

Although with his strength, he can fight with the half-step innate and win.

However, this does not mean that he can compete head-on with the powerhouses of the Innate Realm, the gap between the two is too big.

Now Chu Heng completely imagined that once he appeared, there would inevitably be many people looking for trouble, including many inner disciples of the Innate Realm.

Therefore, Chu Heng urgently needed to improve his cultivation.

He is carrying the Heavenly Baking Furnace Sutra, and the path of cultivation he has taken is destined to consume a large amount of spiritual things.

Yunmeng Lei Ze is the most in line with his requirements, although there are many dangers, but relatively rich, the resources are also extremely rich.

There are people from all walks of life, not only those scattered cultivators, but even the children of the seven major forces of the Yan Domain often enter the Yunmeng Razor to experience.

"Before that, you can specialize in the way of the formation again. Chu Heng touched his chin and said in a deep voice.

The combination of ecstasy incense and formation, I don't know what kind of effect it will have?

Suddenly, Chu Heng was a little expectant.

Before leaving, he decided to go to the Hidden Scripture Pavilion again, exchange some formation-related classics and jade slips, and then go straight to Yunmeng Leize to practice.

However, Chu Heng was just about to leave the alchemy room when the identity token on his waist suddenly floated, and a voice came out of it.

"Come to Purple Moon Peak!"

Hearing this, Chu Heng's complexion changed slightly, and it was just a moment, and many thoughts flashed in his heart.

"What is this old man Liu looking for me to do at this time?"

There is no doubt that the person who sent the message was Liu Xuankong, and this voice Chu Heng was quite familiar with and would not admit his mistake.

"Purple Moon Peak!"

Chu Heng felt that it would be no good for Liu Xuankong to find him, this Purple Moon Peak was not an ordinary place, it was where the main peak of the Purple Moon Cave Heaven was located, usually, even the inner disciples were not allowed to set foot easily, but now Liu Xuankong asked him to go there, and his expression couldn't help but become solemn.

"That's it, since I've been summoned, I'm afraid I won't be able to hide!" In the end, Chu Heng sighed, walked out of the alchemy room, and rushed towards Ziyue Peak.

In fact, he had some guesses in his heart, it had been a few days since he returned from the secret realm, but Liu Xuankong had not given him the identity of a core disciple for a long time, and most of it was related to this at this time.

In other words, he had to leave the Purple Moon Cave as soon as possible, otherwise there might be some trouble coming to him.

With his current strength, he can't handle that kind of trouble.

Unless, he is willing to use the request that the three elders of Liu Xuankong agreed to at the beginning, so that he will definitely be able to stabilize for a while.

But that's not what he wants.

The requirements of the three elders should be used in substance, and it is a bit overkill to block trouble.

Not long after, Chu Heng came to Purple Moon Peak, and there was a bluestone step that winded up at the foot of the mountain, and the trees on both sides were lush and green.

He glanced upwards and ran down the stone steps to the top of the mountain.

As the main peak of the Purple Moon Cave Heaven, the Purple Moon Peak is the highest peak of the entire Cave Heaven, the peak is straight into the sky, the mist is shrouded, the fairy aura is hazy, and the towering palaces are located on the mountain, looming, it is really like the residence of the immortal family.
