Ren Xiaoyao smiled bitterly and said, "I only have three of that kind of fruit in total, and I have already taken all of them, and there are no more." There is a body pill here, which can remove the impurities in the monk's body, and I believe it also has a certain effect on demon beasts, do you think it can?"

Ren Xiaoyao took out a medium-grade Var Body Pill and sent it to Heijing. As soon as Heijing saw that there was an elixir to eat, he let Ren Xiaoyao stuff it into its mouth without saying a word. Ren Xiaoyao's own body is far from enough, but at this time, time is pressing, and he can't take care of it so much, Ren Xiaoyao is the best medium-grade body pill.

"Actually, there is another way to make the refining speed faster on the basis of the current one?" said Heijing, who had eaten the Var Pill, with satisfaction.

"What method?" Ren Xiaoyao hurriedly asked. Black Mirror is a bit greedy, and sometimes takes advantage of Ren Xiaoyao to ask for more pills, but as long as it is not too much, Ren Xiaoyao generally doesn't care much.

"Fighting, fighting through guò, can make my whole body demon blood boil, coupled with deliberate refining, it can speed up the refining of snake gall. Seeing that Ren Xiaoyao didn't blame it for cheating on eating the Var Pill, Black Mirror said with a smile.

Listening to Hei Jing's words, Ren Xiaoyao smiled, stood up, disarmed the Five Elements Clutch Array, summoned the Overlord Knife, turned his head to Hei Jing and said, "You and my brothers have to join forces to fight the enemy many times, but most of the time, you hand over the control of your body to me, and I will dominate it." But my control over your body is not as good as yours after all, if we can achieve the unity of mind and mind, the combat effectiveness should be greatly increased, and when the time comes, we will really join forces against the enemy. I've been running around all these years, and I'm anxious to improve my cultivation, so you and I don't really have much time to hone in on my combat skills. Now take this opportunity to run in and strive to achieve unity of heart and mind. My way of practicing is very tiring and cruel, can you stand it Black Mirror?"

"Hmph, if you can stand it, I can stand it!" said Hei Jing eagerly, and at the same time, his body swung and recovered his true body more than twenty meters long.

"Your body has become a bit bigger, and you are easy to target, so the usefulness of my Overlord Knife will be limited. You'll be about five meters long, so let's get used to this fighting mode first. When you are familiar with this method, you can control the increase or decrease of the body. If you can control your body to grow and shrink at will, our combat power will increase greatly. ”

Ren Xiaoyao saw that Black Mirror got carried away for a while, and changed his body to the maximum, so he reminded. When Black Mirror heard this, he shrunk his body to five meters in embarrassment. The Black Mirror can instantly change the body to the largest and the smallest in an instant, but it takes some time to switch between other sizes, and it is not possible to change it at will immediately.

Seeing that the black mirror was the right size, Ren Xiaoyao held the overlord knife, closed his eyes, and slowly sensed the black mirror. Seeing this, Heijing also closed his eyes and slowly sensed Ren Yao. What this person and beast need to do at this time is to let each other know what the other party is thinking, so that they can fully cooperate. However, Ren Xiaoyao is stronger than Black Mirror in terms of intelligence, and Ren Xiaoyao is the main one in battle, supplemented by Black Mirror. At this time, they induced each other, and it was Ren Xiaoyao who let Black Mirror fully understand what he wanted to do, and then Black Mirror used his body to cooperate.

In this way, Ren Xiaoyao and Heijing stood there quietly, both closed their eyes, and stood for half an hour. Half an hour later, Ren Xiaoyao and Black Mirror opened their eyes at the same time, and each other's eyes were full of battle fanaticism.

Suddenly, Ren Xiaoyao dragged the Overlord Knife on his left and the five-meter-long Mirror King Snake on his right, rushing forward. rushed dozens of meters in an instant, Ren Xiaoyao jumped up, and the black mirror body stood upright, like a giant stick, and was smashed by Ren Xiaoyao on a giant tree with a diameter of more than one meter in front of him, and the giant tree was divided into two halves as if it had been cut by a giant sword.

Black Mirror's body twisted for a while, shaking left and right, and the two sides of the giant tree were separated by force. At the same time, let the Xiaoyao Overlord knife arrive, and with one knife down, the left half of the tree body turned into five pieces, and flew to the left in unison. The tree body on the right was entangled by the body of the black mirror, and with the help of a pull, Ren Yao shot away to the right. When Ren Xiaoyao, who was in the rapid shot, passed by the right tree, the overlord knife was sharpened at will, and the right half of the tree was broken by the roots.

Ren Xiaoyao, who shot away, stepped on a giant tree with a diameter of more than one meter not far away, the giant tree shook, Ren Xiaoyao rebounded with strength, and twisted in the air, the black mirror rolled half of the tree, drew a semicircle in the air, and smashed it on the giant tree that Ren Xiaoyao had just stepped on. With a loud bang, the two giant trees broke off in response. And Ren Xiaoyao, already wielding the Overlord Knife dozens of meters away, launched a crazy attack like an imaginary enemy, in the process of attacking, the Black Mirror often used great force to pump to the boulder, the ground, or become larger, twisting a big tree into several pieces, and twisting a boulder into powder.

......

With such a crazy practice at the expense of mana, Ren Xiaoyao and Heijing fought against the imaginary enemy for less than half an hour, and the mana and demon power of one man and one beast were consumed. This place is the edge of the Demon Beast Forest, and Ren Xiaoyao does not dare to exhaust his mana, and must leave some mana to deal with the dangers that may arise at any time.

After practicing, Ren Xiaoyao gave himself a low-grade Huiqi Pill, a medium-grade Varsity Pill and a medium-grade Feeding Spirit Pill to Heijing, and then concentrated on refining. The Var Pill is also effective against demon beasts, but it is not as obvious as humans. In the practice of half an hour, a large number of black impurities were also discharged from the surface of the black mirror, but they were all rubbed clean during the battle just now.

After resting, Ren Xiaoyao and Black Mirror practiced frantically again, grinding in combat skills, often after three recoveries, a total of nearly three hours, Black Mirror finally fully refined more than fifty snake galls, and his breath also increased slightly.

After that, after grasping the limit, Ren Xiaoyao pulled the training intensity to the maximum, and every time he finished training, one person and one beast were exhausted, especially Heijing, in addition to being extremely tired in his body, he was left with a dense overlord knife wound on his body. It's just that these knife wounds on the body of the Mirror King Snake are extremely small, in addition to making it feel pain, they do not hurt its roots, and after each round of rest, through the refining of the body pill and snake gall, coupled with its own healing ability, these knife wounds will quickly disappear, and Black Mirror's body has become more and more black and bright under this almost devastating training method.

In this way, in less than a day, after swallowing nearly one hundred and fifty snake gall bladders in a row, plus five medium-grade Cutting Pills and seven Medium-grade Feeding Spirit Pills, Black Mirror finally reached the limit of a fourth-level demon beast and began to advance.

For the upcoming promotion process, Black Mirror instinctively felt scared, and his body involuntarily became smaller and wrapped around Ren Xiaoyao's waist, not wanting to advance. And Hei Jing's scared mentality and the feeling of being about to burst in his body, Ren Xiaoyao could clearly feel it, and couldn't help but smile and pat Hei Jing's head.

"Don't worry, I won't let you have an accident. ”

After being comforted by Ren Yao, the black mirror slowly regained his confidence, the red light flashed in the snake's eyes, and his body quickly became the largest. The body of more than 20 meters is horizontal on the ground, swinging constantly. In order to cooperate with Black Mirror's promotion, Ren Xiaoyao had to lie down with Black Mirror, and this human snake's posture was extremely strange.

After a while, Black Mirror's body swung more and more frequently, and finally even kept whipping the ground, pulling out a huge pit on the ground within a hundred meters, and the ground was whipped extremely hard. This process can be bitter Ren Xiaoyao, compared to the body of the black mirror, Ren Xiaoyao's body seems a little small, driven by the swinging black mirror, if it is not for the black mirror has been paying attention to the swing of the head, I am afraid that Ren Xiaoyao will be more bumpy.

After beating the ground like this for more than half an hour, the hexagonal prism-like scales on the surface of Black Mirror's body became even darker, and they flashed with black light.

At this time, the black mirror, which was a little confused in his head, unconsciously sucked up Ren Xiaoyao's blood. This scared Ren Xiaoyao out of his mind, Black Mirror's current strength is much stronger than it was at the beginning, if he sucks it with all his strength, the blood in Ren Xiaoyao's body will have to be sucked by half, two or three, and Ren Xiaoyao will be an adult.

As soon as he felt that the black mirror was sucking his own blood, Ren Xiaoyao hurriedly stretched out his left hand, and pinched it frantically, a fireball quickly rose in the center of the palm, and quickly split into five, spinning and flying towards the tail of the black mirror, as soon as it touched the body of the black mirror, the five fireballs just touched together again, and with a loud "bang", the body of the black mirror, which was difficult to be injured by the high-grade spiritual weapon, was blown black, dozens of black scales were blown off, and the snake blood slowly seeped out of the wound.

At this time, the best way to deal with the black mirror is to use the white snow ring, but the role of the white snow ring is extremely unfixed, Ren Xiaoyao did not dare to use it casually to deal with the black mirror that had been connected with himself before he fully understood the effect of the white snow ring, so he used his best fireball technique, hoping to wake up the black mirror.

Under the severe pain, Heijing really came to his senses, looked at Ren Xiaoyao, who was pale, with an embarrassed face, between the ups and downs of his body, the blood flowed backwards, and he actually sucked Ren Xiaoyao and most of the blood back into his body just now. However, this time it is no longer pure Ren Yao's blood, but snake blood with a small half of the black mirror. Being flowed into his body by the snake blood of the black mirror, Ren Xiaoyao immediately felt a burst of blood boiling, his eyes suddenly turned red, and his spirit became a little violent.

"Enough!"

Ren Xiaoyao shouted at Black Mirror in his mind, and only then did he stop Black Mirror's backflow of blood.

Black Mirror kept apologizing to Ren Xiaoyao in his thoughts, his body stopped swinging, and he forgot for a moment that he was in the process of promotion. Ren Xiaoyao didn't want to have any psychological burden on Black Mirror in the promotion process at this time, smiled at it slightly, swallowed a medium-grade Huiyuan Pill and a medium-grade Huiling Pill, signaled that he was fine, and let Heijing concentrate on promotion.

"Although you sucked my blood just now, and let some of my blood flow into your body, my weakness will also affect you. So in the next promotion process, you must always stay awake and never repeat what you just did.

There are more than fifty snake gall bladders here, even with this medium-grade Var Body Pill and this medium-grade Huiling Pill, you have eaten them, you need a lot of energy during the promotion process, you not only have to maintain a full body during the promotion process, but also refine these energies into the body through promotion. Ren Xiaoyao stuffed all the remaining snake gall bladders, as well as a medium-grade Var Body Pill and a medium-grade Huiling Pill, into Black Mirror's mouth.

"Xiaoyao, I feel that there is a force in my body constantly emerging out, but I am trapped in my body and cannot be released, which makes me uncomfortable. I figured out guò to fight you to unleash this power. I feel like as long as I release this power, I can molt and advance. Black Mirror hesitated for a moment, and actually came up with the idea of fighting Ren Xiaoyao.

"Haha, it's very interesting that you have this kind of thought, you and I can guess some of each other's ideas, and we are familiar with each other, so it must be more interesting to fight. It's okay for me to attack you with all my might, right?You're at the critical moment of advancement, and it's okay to use guò to fight to inspire and unleash the power that prompted you to advance, but don't let you get hurt, otherwise the gains outweigh the losses. Ren Xiaoyao said with a laugh, and his bold spirit was spontaneous.

Since Ren Xiaoyao and Black Mirror became one, they have always joined forces against the enemy, and they have not fought each other yet.

"I feel that the strength of my body has reached its best condition now, and it is no problem to withstand the attack of your Overlord Knife in a short period of time, so let's get started. "The power in Black Mirror's body is accumulating more and more, and he is eager to release it, and he is looking forward to the battle with Ren Yao.

"Hit!"

Without saying a word, Ren Xiaoyao summoned the Overlord Knife and slashed at Black Mirror's body with a single sword, leaving a shallow scratch. And the black mirror, raising the giant tail, pulled towards Ren Xiaoyao, and was dodged by Ren Xiaoyao.
