"Where is the limit of this kid, this time he even refined three Regeneration Pills!" Yun Feng was shocked in his heart, knowing that the refining medicinal materials given to Chu Yun were only ten.

Three finished pills were refined from ten medicinal herbs, and the success rate was really too high!

In fact, he didn't know that in fact, Chu Yun had used these ten medicinal materials to successfully refine five regeneration pills. One of them was given to the hexagram immortal. The other was reserved for his father-in-law, Shu Tianhao. The remaining three were handed over as the results of the mission.

If he knew about this, it is estimated that Yun Fengfeng was so surprised that his mouth opened so wide that he dislocated.

"Develop a medium elixir that can improve the combat effectiveness of monsters. Seeing the new task in the jade plate, Chu Yun fell into deep thought.

This task is only a few sentences, but the difficulty is at least ten times more than the previous completed task.

Because all the previous tasks are "refining." "There are ready-made Danfangs. And now the task is to "develop." "That is to say, there is no Danfang, and Chu Yun needs to research and create.

The skyrocketing difficulty of the task made Chu Yun keenly aware of the thoughts of the Yun family's higher-ups. It seems that the plan he has implemented "has paid off." If you can complete this task, then your status will also be improved.

Thinking of this, Chu Yun couldn't help but feel a fighting spirit in his heart.

Although there were many alchemy masters and master-level immortal concubines around him, Chu Yun did not intend to rely on them. At the level of alchemy grandmasters and masters, the elixirs refined will have a strong personal style. Chu Yun alone, there are many different styles, which is too eye-catching.

At the time, Chu Yun also found that he could also realize many things in alchemy. Referring to these things, he comprehended the efficiency of the Immortal Bag World Law Open, and it was improved again.

Besides, the Ship of Bliss and Joy was going to be hidden. It's just that this trump card needs to be used for a trivial matter like alchemy, and it is not Chu Yun's style.

Therefore, all along, it was Chu Yun who operated it himself. It's just that after every alchemy, all the immortal concubines will comment, and every sentence is insightful, which benefits Chu Yun a lot.

Chu Yun calmed down and thought.

The elixir that improved the combat effectiveness of monsters, in fact, he had already seen a lot. Heavenly Storm Pill and Heavenly Crystal Pill are all such pills. It's just that the effect of the former is temporary, and the effect of the latter is permanent.

However, the instantaneous increase of the Heavenly Storm Pill is very huge, and it can make a monster at the peak of the spirit demon exert the combat level of the demon robbery. At one time, Chu Yun relied on this elixir to fight.

As for Tianjingdan, the refining medicinal materials are somewhat special, and they need to be ownerless Tianjing. Chu Yun had refined a large number of them, but most of them were consumed on psychic snakes, moon rabbits and other demon beasts, and now there is no stock on his body.

"If you combine the Heavenly Storm Pill and the Heavenly Crystal Pill, ......" Chu Yun couldn't help but think.

The Heavenly Storm Pill and the Heavenly Crystal Pill are the Dan prescriptions of Xingzhou, and they naturally have no effect in Danzhou. However, Chu Yun could learn from the ideas of the two, summarize and study, learn from each other's strengths, and refine a new elixir.

Seven days later, he handed over an elixir.

Tian Haodan!

Medium elixir can improve the cultivation of monsters, and increase the combat power to an extremely considerable degree in a short period of time.

After testing the efficacy of the medicine, the high-level members of the Yun family were shocked.

Originally, they just wanted to test Chu Yun's potential, but they didn't expect Chu Yun to really complete the task, which greatly exceeded their expectations.

The medicinal effect of Tianhaodan is surprising. Several family elders who tested the efficacy of the medicine concluded on the spot that this Tianhao Pill would be an elixir that would change the pattern of the Eight Great Hidden Families. Once mass-produced, its excellent efficacy will inevitably replace the standing elixir, and the influence will be widespread.

The only fly in the ointment is that refining this kind of Tianhao Pill requires an ownerless demon crystal. This kind of medicinal material, although the Yun family also has inventory, there are not many of them. Compared to other medicinal herbs, this kind of thing is also difficult to collect and replenish.

Of course, on the whole, it is definitely flawed. The mid-level Tianhao Pill is easier to refine than the high-grade pill, and the success rate is also greatly increased, which is definitely suitable for equipping the Yun family team.

Unintentionally inserting willows into the willows, this is the general mentality of the Yun family's top management.

"Found a treasure!" while secretly blocking any information about Tianhao Dan, they immediately transferred Chu Yun from the Nineteen Sects and directly arranged for him to be sent to the Research Institute.

The R&D Institute is the existence of the 21st Institute. It only serves the entire family, and the people inside are all alchemy masters, and even alchemy masters. Their task, if nothing else, is to develop new elixirs. Everyone has the right to freely dispose of the Yun family's medicinal herb bank.

Chu Yun's transfer caused a lot of discussion in the Yun family. Although the news of Tianhao Dan was strictly blocked, but the collective determination of the family elders, none of the Yun family questioned the mouth, and the people just focused on Chu Yun's body, marveling at his terrifying talent.

Yun Feng had long expected this day, but he didn't expect that this day would come so quickly. Although he was extremely reluctant, he had no choice but to send it to him in the end.

"From now on, please take care of the nameless lord!" Yun Feng bowed and saluted, and kept looking at Chu Yun until Chu Yun's back completely disappeared in his eyes, and then he withdrew his gaze.

Chu Yun joined the research institute, and his status immediately increased greatly. Yun Feng used to be his boss, but now he is also under him. The members of the institute have a transcendent status and have many privileges in the family. Even the leaders of the twenty-one sects must be treated politely.

With a new status, Chu Yun's vision suddenly rose to a new level. The Yun family's countless canonical history secret books are open to it.

Although it was not enough to get in touch with the most core family secrets, Chu Yun had already collected the news about his mother, one by one, "The Moon Frost King lives in seclusion in the Heavenly Abyss Lanze. ”

Chu Yun was greatly excited, but Tianyuan Lanze was one of the secret realms of the Yun family, and even the descendants of the Yun family could not enter it at will.

If you want to enter the Abyss Blue Color, you can only get permission from the Moon Frost King.

From this information, it is speculated that the situation of the Moon Frost King is still okay. At best, it is house arrest, not captivity.

However, a new question has arisen, how can Chu Yun, an outsider, obtain the approval of the Moon Frost King and have the right to enter and exit the Heavenly Abyss Lanze?

Even though it was his own mother, the Moon Frost King didn't know about the situation on Chu Yun's side. Tianyuan Lanze is even far away from the Yun family's base camp and is located in a remote area. Even if it's an excuse to "enter by mistake", it's hard to find.

Corpse time, Chu Yun's plan is stuck in this level, and it is difficult to make progress.

After all, he is only one person, and he is alone. Although he joined the research institute, he was not as free as before. There are people around to keep you safe at all times.

The three-year-old child of the Yun family knows that every member of the research institute is a baby bump of the Yun family.

In desperation, Chu Yun could only choose to wait.

Buzz .......

A bōbō black gold beetle surged out from the magnificent god and demon secret gate, like a long river of black oil, and slammed into the demon plant defense line that Chu Yun had carefully built.

Bang Bang Bang!

The slender wicker danced wildly, whipping the black gold beetle, setting off pieces of broken limbs and blood rain, and the effect was outstanding.

This is a mad knife and a willow.

Although it is only a medium demon plant, the melee effect is sè, and the attack range is wide, and just planting a row can block the offensive wave of the black gold beetle.

What's more, the crazy knife turbulent willow has less loss of resources, and it is a very "hard-working" type of demon plant.

They are generally three feet tall, and the branches are nèn yellow sè, like a thin and soft leather whip. The branches are covered with willow leaves, which are narrow and sharp, like blades, and shimmer with a pale green sè.

The black gold beetle rushed unabated, and thousands of wicker mad demons danced wildly, forming a powerful meat grinder, attacking instead of defending, and standing still.

After the offensive of the three bōs, Chu Yun closed the secret gate of the gods and demons.

The various severed limbs and remnants of the black gold beetle were spread on the ground, gradually turning into shattered chaos demon crystals. From a distance, on the surrounding land of each mad sword and chaotic willow, there are fragments of black sè chaos demon crystals, which are somewhat spectacular.

Without the black gold beetle, the wild knife and the willow all hung down quietly, and the thick branches, slender nèn yellow branches, and the long and narrow willow leaves like emerald, swayed gently in the breeze. It's like a dream, and it's a dream. It is very different from the previous rampant and bloody rain.

These crazy knives and chaotic willows were carefully selected by Chu Yunqian. Produced in the barbarian continent, it is as quiet as a virgin in normal times, but once it is attacked, it will dance in willow branches and burst out with terrifying attack power.

Practice has proved that Chu Yun's decision is undoubtedly extremely wise.

For a few costs, he purchased hundreds of Wild Blade Turbulent Willows from the Blue Emperor and planted them on the edge of the Immortal Sac World.

At first, these crazy knives were chaotic willows, and there were only thirty big demons, and the rest were all small demons. However, Chu Yun opened the secret door several times, and the mad knife and chaos willow were strangling a large number of black gold beetles, and now all of them are at the peak of the big demon. Cultivation has reached its limits.

Of course, these demon plants naturally can't directly absorb the Chaos Demon Crystal.

The Chaos Demon Crystal was digested by the entire Immortal Capsule World, enriching the vitality, and even slightly improving the cultivation of the Array Eye Monster. The Crazy Knife Turbulent Willow also benefited from this, and received a very small part of the essence infusion, and the cultivation skyrocketed.

The next step is to fold and transplant branches to double the number of these wild knives and willows.

This cultivation method has a limit on the success rate, and at the same time, it will lose a lot of cultivation of the body, and the transplanted branches need to be carefully cared for.

Chu Yun naturally didn't have to do everything, and the transplanting work was done by the Bliss Immortal Concubines. Although after transplanting, the cultivation of the Crazy Knife Turbulent Willow will generally drop to the level of the little demon, but with the secret gate of gods and demons, as well as the digestion power of the immortal sac world, their cultivation will soon be promoted to the peak of the big demon.

With such repetition, the number of crazy knives in Chu Yun's hands will increase more and more. Not only can it be commonly planted in the fairy sac world, but the surplus can also be sold to others to generate income. ！。
