After kissing Qian Renxue goodbye, Wang Kai entered the cultivation chamber again, locked the door, and immediately thought about it and entered his own small plane.

    This time, he was going to refine another human level Four Pill - qinglingdan!

    Like yanghundan, qinglingdan is also the fourth grade elixir. However, in terms of refining difficulty, qinglingdan is obviously much more difficult than yanghundan.

    After preparing all the medicinal materials and summoning the chaotic mountain and river tripod, Wang Kai''s soul surged, and a wisp of 3000 burning Tianyan was injected into the medicine tripod in front of him. When the temperature in the medicine tripod reached the point, he gently waved his right hand and absorbed the Qingling flower, the main material of Qingling Pill - the fourth product of human level.

    Refining and purifying medicinal materials, mixing pills and coagulating pills, all kinds of cumbersome and fine steps, Wang Kai almost finished at one go without any stagnation.

    The young pill has become. He feels that the first nine pills are full of medicine, but there are still some potholes. Wang Kai nods with satisfaction.

    This alchemy was also very successful!

    With his hands constantly changing, Wang Kai''s spiritual power and soul power began to be consumed, and then condensed between Wang Kai''s two hands, turned into wisps of white Dan gas, poured into the Dan furnace, and began the process of warming and raising young Dan in the fourth step.

    In another half an hour, Wang Kai sensed that the pills in the furnace had become full and shiny under the lingering Danqi. Wang Kai gently patted both sides of the chaotic mountain and river tripod, and the three thousand burning Tianyan in the tripod went out in an instant. At the same time, nine yellow Qingling pills the size of pearls were shocked out of the tripod.

    He picked up a jade bottle that had already been prepared on one side. Wang Kai''s hands crossed an arc in the air. Nine Qingling Dana entered the jade bottle. Immediately, he put the medicine bottle under his nose and sniffed it gently.

    Suddenly, a refreshing fragrance emanated from the mouth of the bottle. With his spiritual power, Wang Kai can clearly know that the medicine power of this batch of Qingling pills is definitely better than the previously refined soul nourishing pills!

    The pill fire continued to rise, and Wang Kai followed suit and refined the remaining two pairs of medicinal materials into a Qingling pill. At the end of alchemy, Wang Kai looked at the thirty-nine and twenty-seven yellow elixirs in his hand. A satisfied smile appeared on Wang Kai''s face.

    "After refining these Qingling pills, I can certainly break through the realm of one mind and six uses!" thinking, Wang Kai crossed his knees, took out a Qingling pill, swallowed it into his stomach and began refining.

    Not long after, wisps of slightly warm pale yellow medicine spread in Wang Kai''s abdomen and continued to rush towards Wang Kai''s knowledge. When these drugs entered Wang Kai''s sea of knowledge, they quickly turned into light yellow drug mist and floated in Wang Kai''s sea of knowledge.

    "Refine it for me!" holding his breath, Wang Kai concentrated all his spiritual power in the sea of knowledge. One spiritual power wrapped around the Yellow medicine fog with his mind and began crazy refining.

    With Wang Kai''s refining, clouds of yellow medicine fog continue to dilute and dissipate. At the same time, Wang Kai''s spiritual power is also rising.

    Of course, while the existing medicine in Wang Kai''s knowledge of the sea was continuously refined, new medicine fog also poured out from Wang Kai''s abdomen and continued to rise into Wang Kai''s knowledge of the sea for supplement. Dozens of minutes later, although the medicine fog in Wang Kai''s knowledge of the sea was thin for several points, it was still not refined.

    At this time, Wang Kai''s spiritual strength has reached a peak. With a faint sound of rupture in the sea, Wang Kai only felt that the film that bound him to know the sea had been broken!

    With this crisp sound, Wang Kai''s knowledge of the sea began to expand slowly. Finally, the volume of his knowledge of the sea increased by about 10% before he stopped slowly. While expanding his knowledge of the sea, Wang Kai''s total spiritual strength increased again, and his spiritual strength naturally completed a breakthrough and reached the state of one mind and six uses.

    His mental strength soared, and Wang Kai''s speed of refining medicine increased again. Ten minutes later, he knew that the fog in the sea was finally completely digested, and the medicine power of this qinglingdan was exhausted.

    "If it works... This Qingling pill has helped me to achieve the leap of one mind five uses and one mind six uses, and it will also fill 2% of the additional mental power required for me to continue to break through the one mind seven uses! In this way, the drug power of a Qingling pill should be about 1.25 times that of the soul nourishing pill!" I estimated the drug power of Qingling pill, Wang Kai continued to take out the second qinglingdan and put it in the entrance, and began the second round of refining.

    Ten percent, seventeen percent, twenty-four percent... With the entrance of Qingling pills, Wang Kai''s spiritual power is getting closer and closer to the seven uses of one mind, but at the same time, the effect of each Qingling pill is also reduced from eight percent to one percent.

    "What a pity! It seems that I must refine the soul strengthening pill before I can break through the state of one mind and seven uses!" after the refining of 20 Qing spirit elixirs, Wang has only filled about half of the spiritual gap from the next breakthrough. It seems that he must refine the five human soul strengthening pills before he can complete this breakthrough!

    "Let''s do it first. Now we can start today''s practice of ''taixuan town Tiangong''!" Wang Kai took back the chaotic mountain and river tripod, and then continued to sit cross legged.

    Zhuang soul pill is the fifth grade pill of human. If Wang Kai wants to refine it, he must maintain the best mental state and concentrate. Today, Wang Kai has refined three heats of Qingling elixir, and his spirit is a little tired. If he rashly tries to refine five products of elixir, the possibility of failure is very high. Therefore, Wang Kai did not continue to refine elixir, but began his daily spiritual cultivation.

    Compared with the cultivation chamber, the concentration of soul power in the small plane is slightly lower for the time being. However, when practicing in the small plane, Wang Kai will not be affected by the world''s malice, but the actual practice efficiency is higher!

    The whirlpool of soul power condensed, and the soul power in the small plane constantly surged around Wang Kai, pushing the wave of soul power in his body higher and higher, one round, two rounds

    Fifty four rounds of soul power surged away, and a large amount of soul power poured into Wang Kai''s body through his pores, expanding Wang Kai''s muscles and veins, and constantly bringing new soul power and experience to his body.

    "Practice taixuan town Tiangong, source experience + 223!"

    Slowly opened his eyes, Wang Kai''s eyes showed a happy look! Although Wang Kai''s cultivation speed in the small plane has decreased a lot compared with that in the angel secret realm, Wang Kai''s cultivation speed has almost increased by half compared with that in Douluo mainland! Moreover, it can be predicted that with the continuous improvement of the concentration of soul power in the small plane, Wang Kai''s cultivation speed will be faster and faster.

    "Then today, please ask the master to take me to get the fifth Soul Ring! After getting the fifth soul ring, the master should not ask me for anything for a while. I can also take the opportunity to compete for the opportunity of ice and fire eyes!" Wang Kai withdrew from his position and returned to the cultivation chamber.
