After many persuasions by Jiang Yun and stalking, Bai Feng finally agreed to go with Jiang Yun to explore the Yin Evil Land.

The two came to the cave and went straight to the tunnel, one was born and the other was cooked, this time Jiang Yun's speed was significantly improved compared to the last time, which made Bai Feng a little surprised, and spit out in his mouth, "It seems that your kid is not the first time to come!"

"Well, the last time I was investigating the enemy, I came in once. Jiang Yun said with some embarrassment, after all, this is also Bai Feng's territory, and he came to his house quietly, so it was wrong for him to think about it.

The two came to the ice room, Bai Feng saw that the bed had been moved, and he knew that Jiang Yun was afraid that he had entered the ice cellar below, knowing this, Bai Feng looked at Jiang Yun with some meaning, after all, the ice cellar below is not something that anyone can find, so he had to take a few glances at Jiang Yungao.

"You kid, you're quite good at flipping things!" Bai Feng looked at Jiang Yun rather playfully.

Under the gaze of Bai Feng's eyes, Jiang Yun looked a little embarrassed, after all, it was his own fault, and he could only accept Bai Feng's questioning.

The two jumped straight into the ice cellar, the surroundings were dark, the visibility was extremely low, Jiang Yun only heard a sound of water as soon as he entered the ice cellar, the mysterious black snake went out again, straight to Jiang Yun, fortunately, Jiang Yun has spiritual sense, although he is in the dark, but he still knows the situation in the ice cellar, one sideways dodged the sneak attack of the black snake, the black snake impact did not stop and directly hit the ice wall, the solid ice wall actually appeared a small hole, although the hole is small but its depth is unpredictable, this black snake attack can be described as extremely fierce, if this blow is in the human body, I am afraid that there will be a blood hole。

The black snake didn't care about the white wind beside Jiang Yun, and came straight to Jiang Yun, obviously treating Jiang Yun as a plate, the black snake spit out the letter, staring at Jiang Yun vigilantly, the snake's body slowly twisted, ready to attack at any time. One person, one snake and two looked at each other, but no one dared to act rashly.

Seeing this, a trace of joy appeared on Bai Feng's face, and with a wave of his big hand, the entire ice cellar instantly lit up, covered with silver-white light.

The ice cellar was bright, but the black snake hid in the Yin Evil Spirit Spring as if it was afraid, Jiang Yun was shocked when he saw this, it seemed that this Bai Feng knew this, and he also knew the existence of the black snake.

"What do you want to do here?" Bai Feng turned around, looked at Jiang Yun next to him, and wondered. After all, although the Yin and Evil Land can produce Yin and Evil Qi, ordinary people don't dare to absorb it at all, and they are even very afraid, Bai Feng is quite interested in Jiang Yun's purpose of coming here.

"Refining the Yin Demon Spirit Bead", Jiang Yun did not hide his purpose for coming here, after all, Jiang Yun was not sure that he could hide the powerhouse of the Transformation Yuan Realm in front of him, so it was better to treat the truth and win favor.

"What is the Yin Demon Spirit Bead, I have never heard of it?" Bai Feng heard Jiang Yun answer, a trace of curiosity flashed in his eyes, he had been walking the continent for many years, and he had never heard of the name of the Yin Demon Spirit Bead, but he was very curious about it.

"Otherwise, if I succeed in refining, give one. Jiang Yun said after thinking deeply, after all, it is not a problem to refine a few Yin Demon Spirit Beads here, and it can be regarded as repaying Bai Feng's kindness.

"Okay, then I'll wait for your good news", hearing that Jiang Yun was willing to refine a Yin Demon Spirit Bead for himself, Bai Feng was extremely excited, after all, Jiang Yun was so begging, Bai Feng knew that the Yin Demon Spirit Bead was absolutely extraordinary, and he could get a treasure, so why not Bai Feng. Immediately, the aura in Bai Feng's mouth surged, and he spit out a word, "You are all going to retreat, you are not allowed to disturb the son's alchemy, get out!"

As soon as these words came out, the black snakes in the spiritual spring rushed outward, there were dozens of them, and on the ice wall, there were also many creatures appearing, fleeing outward, this scene really frightened Jiang Yun, he never thought that there were many strange things in this ice cellar, and he didn't even find it, if it wasn't for Bai Feng this time, he was afraid that it would be more than lucky.

"You can rest assured that these black snakes will protect the Dharma for you. Under Bai Feng's orders, those black snakes were all hiding in the corners of the four axes, staring vigilantly around, like loyal bodyguards.

After Bai Feng left, Jiang Yun also began to refine the Yin Demon Spirit Bead, the natal spirit sword appeared out of thin air, the spirit sword was in the air, the tip of the sword pointed directly at the spirit spring, and a strange suction force came out of the tip of the sword. The spiritual spring poured into the spiritual sword with all the suction power, and Jiang Yun did not suck the spiritual spring out with gratitude, leaving some behind.

Jiang Yun sat cross-legged, the spirit sword was located in front of Jiang Yun, the sword body trembled slightly, and the absorbed spirit spring turned into drops of black viscous balls and slowly fell. Jiang Yun's spiritual power gathered in both hands, and the spiritual power formed a film of light, which firmly wrapped the small black ball, and when the small black ball completely dripped off, it actually formed a black ball the size of a football.

There seems to be a flow of breath on the black ball, and its surface also reveals a strange yin and evil aura, exuding a dispensable cold aura, which is different from the general cold aura, the yin and evil qi hits the soul directly, making it difficult to resist, if it weren't for Jiang Yun's natal spirit sword, which can resist the erosion of the yin and evil aura, even if the strength is high, he would not dare to stay here.

Jiang Yun used his aura to wrap the black ball, and a burst of flame burned in his hand, this fire was not an ordinary fire, it was the natal fire of the fire cloud rat, and its power and temperature were far beyond ordinary flames, only some strange fires could match it.

Jiang Yun dribbles with one hand and controls fire with the other, although he is single-minded, his control ability is definitely amazing, if he is replaced by another person, he is afraid that he will not be able to do such a realm no matter what, all because Jiang Yun has spiritual sense. The powerful spiritual sense is enough for Jiang Yun to squander, and only one person can control several spiritual qis, so it is naturally no longer a problem to use two minds.

Under the scorching of the flames, the black ball did not move at all, but there was water vapor slipping away on it, and the flame temperature was extremely high, enough to evaporate everything, and the reason why the black ball was burned with the flame was to extract a more pure yin evil qi and facilitate the refining of the yin evil spirit bead.

The use of flames for a long time really consumes spiritual energy, and if it is replaced by another person in the same realm, I am afraid that the spiritual energy will already be consumed, and it will not be able to refine the Yin Evil Spirit Bead at all.

After refining the spirit bead for a long time, the aura in Jiang Yun's body was also consumed, and the Nine Thunder Imperial Sword Heart Method moved as he wished, absorbing the aura while releasing the aura, such torture was very unbearable, if it was replaced by someone else, he would have been unable to hold on to it for a long time, and he would have to give up halfway to give up refining the Yin Evil Spirit Bead. Of course, if there is a slight slack in the refining process, the success rate of refining the Yin Demon Spirit Bead will be greatly reduced. Even if the refining is successful, its effect will be greatly reduced, which is not what Jiang Yun wants to see.

The most important thing in alchemy is to have no distractions, although it seems to be easy to do, but it is actually very difficult to do, but for Jiang Yun, who has a strong spiritual sense, it seems very simple. At this moment, Jiang Yun completely ignored the external situation and was only dedicated to refining the Yin Evil Spirit Bead, the flame in his hand gradually faded, and the round ball became a lot smaller, only the size of three or four ping-pong balls, but because of this, the Yin Evil Qi that gathered into a small ball trembled sharply, wanting to break free from the shackles.

Jiang Yun didn't dare to be careless, and the aura constantly surrounded the yin and evil qi, wanting to block the escape of the yin and evil qi, but the yin and evil qi was far from being comparable to the aura, in front of the yin and evil qi, the aura was very weak, and he didn't dare to block the spread of the yin and evil qi at all.

Seeing this, Jiang Yun didn't dare to be careless, and put all the aura into the natal spirit sword. After absorbing the aura, the natal spirit sword spit out a large amount of aura, and the aura spit out by the natal spirit sword is different from the past, but the aura becomes fierce as if it has been blessed, and it can actually suppress the yin qi alive, making the yin qi continue to retreat and finally condense into a ball, and the escaping yin qi is absorbed by Jiang Yun and integrated into Jiang Yun's dantian.

Taking advantage of the time when the yin and evil qi condensed into a group, Jiang Yun refined the essence of the medicinal herbs with one hand, and controlled the yin and evil aura with the other, the combination of the two, with the integration of the essence of the medicinal materials, the yin and evil qi became gentle, just like a docile sheep no longer resisted Jiang Yun's control, but moved with Jiang Yun's mind, with the cooperation of the yin and evil qi, Jiang Yun's success rate in refining the Yin and evil spirit beads increased by a few points.

The thunder in Jiang Yun's hand flickered, and the thunder was directly slashing towards the yin qi. The reason why Jiang Yun used the thunder to slash at the yin evil qi was because the thunder was the most domineering and aggressive aura in nature, and its purification effect far exceeded that of the flames.

Under the erosion of the thunder, the yin and evil qi kept scattering and reuniting, and so on, as soon as the thunder came out, the black snake that was scared to look at the wind around was hiding in Tibet, but Jiang Yun did not find this scene, because Jiang Yun was preoccupied with the yin and evil qi at this moment, and he did not dare to slack off, otherwise the refining failed, and it would be troublesome, after all, the yin and evil land is not so easy to find, and if you can find the yin and evil land this time, it will be difficult to say next time.

Beads of sweat dripped from Jiang Yun's cheeks, Jiang Yun at this moment can be described as exhausted, the use of spiritual sense makes him very tired, and there is not much spiritual power left in his body, but now is also the most critical moment. Next is the most critical step in refining the Yin Demon Spirit Bead - the Condensation Bead.

As the last step in refining the Yin Demon Spirit Bead, the Condensation Bead also has extremely strict requirements for the refiner, not only for the aura, but also for the refiner's physical fitness. After all, when condensing the Dan, you must always pay attention to the outbreak of the evil qi, if you don't do it, you will be burned, and then it will be bad if a Dan destroys people.

Jiang Yun used his spiritual sense to probe the subtle changes of this yin and evil qi, the spiritual energy in his hand surged, and the strong pressure continuously compressed and condensed the yin and evil qi into small balls, and the surrounding temperature dropped and the monstrous cold qi was wrapped around Jiang Yun, even though Jiang Yun's body was surrounded by cold qi, but his body was sweating profusely and was incompatible with the surrounding environment.

Of course, the reason why Jiang Yun didn't stop sweating was because his energy and spiritual power were consumed too quickly, and in the face of such consumption, even if Jiang Yun had a very sufficient spiritual energy background, he couldn't afford to squander it, not only was the spiritual energy so scarce, but even the spiritual sense was very little, and now he could only use his eyes to observe the changes in the yin and evil qi.

Once the condensation bead starts, it can't be abandoned halfway, otherwise it can only be empty of people and money, Jiang Yun carefully controls the yin and evil qi with one hand, and takes out the spirit stone in his arms with the other hand, and absorbs it directly, so if others see it, they are afraid that they will feel distressed, after all, directly absorbing the spiritual energy in the spirit stone will not only waste the spirit stone, but also harm the body, but the matter has come to this point, Jiang Yun has no other way.

Although he can no longer use his spiritual sense to observe the changes in the Yin Evil Qi, Jiang Yun's eye observation power is not much weaker, and Jiang Yun still has confidence with his naked eyes alone, after all, this is not the first time he has refined the Yin Demon Spirit Bead.
