Hua Yue'er was naturally very happy when she heard Kong Yu's words to let her stay, but her face pretended to be not very reluctant, and it was Kong Yu who kept her, so she would stay. Seeing Hua Yue'er's expression, Kong Yu just smiled, walked to the front and began to cultivate.

Kong Yu has been neglected in the Kong family since he was a child, so he is actually very repulsive to outsiders and very eager for the care of others. Wandering on this desert island, and getting an adventure that others can't imagine, this is the biggest secret in his heart, just waiting for his future cultivation to realize his wishes, but he didn't expect to meet Hua Yue'er and Hua An.

Although Hua An forced him to test the medicine, it was also possible to increase his strength, and now he asked Hua Yue'er to teach him the five bird plays, the true treasure of the Hua family, although he didn't know the intention, but this could be regarded as a kind of concern for himself. Kong Yu, who had never experienced such a thing, was actually a little moved in his heart.

Moreover, when Hua Yue'er got along, Kong Yu had already found that although Hua Yue'er had a little temper, her mind was very simple, perhaps because the two were of the same age, Kong Yu felt very comfortable with Hua Yue'er, so for this reason, Hua Yue'er would stay here to watch him cultivate.

First of all, he practiced the five fowl opera taught by Hua Yue'er just now, and Kong Yu had already memorized the various moves just now, but he was not skilled enough to perform them, but after practicing them a few times, he was still decent. This made Hua Yue'er, who was watching from the side, very surprised, you must know that he has cultivated these five bird plays for a long time before he has achieved something, and Hua Yue'er also found that when Kong Yu performed these five bird plays, there was an inexplicable and terrifying momentum around his body.

After cultivating the Five Fowl Opera almost, Kong Yu began to cultivate the Heart Destroying Palm, the Great Fu Demon Palm, then the method of Yi Muscle Forging Bones, and finally the Nine Yin White Bone Claw. Seeing Kong Yu cultivating so hard, sweat constantly flowing down from Kong Yu's body, Hua Yue'er suddenly felt a sense of distress, especially when she saw Kong Yu cultivating the Yi Tendon Bone Forging Method and the Nine Yin White Bone Claw, she actually felt like she couldn't help crying.

Looking at the coconut tree again and again, boiling his own body, and then inserting his fingers into the coconut tree again and again, cultivating Kong Yu of the Nine Yin White Bone Claw, Hua Yue'er disappeared little by little because of Kong Yu's fear of her Nine Yin White Bone Claw. Hua Yue'er knew in her heart that there must be some distressing story behind Kong Yu, but now she wouldn't bother to ask, just watched quietly from the sidelines.

Hua An did not appear for seven days in a row, but Kong Yu took advantage of these seven days to master the various moves of the Five Fowl Opera, and also fought with Hua Yue'er from time to time. However, without using True Qi, the two are evenly matched, and if True Qi is used, Kong Yu will not be Hua Yue'er's opponent, even if Kong Yu uses the Nine Yin White Bone Claw, it is useless, because Hua Yue'er is no longer afraid of the Nine Yin White Bone Claw.

In this way, on the eighth day, Hua An finally appeared, first checked Kong Yu's physical condition, and then took Kong Yu and Hua Yue'er to the underground laboratory. At this time, the underground laboratory is a little different from before, and there are several more huge glass containers.

In the center of the underground laboratory is the largest container, made of extremely thick steel on three sides, and only one side is clear glass, which can be seen inside. Around this huge vessel are five large terrariums, each filled with liquid and varying in color, white, cyan, black, red, and yellow.

"Boy, go to the central container, you will test the medicine for me from today, these are my life's work, you don't want to spoil me. Also, it will hurt a little when you try the medicine later, if you can endure it, it will naturally have a lot of benefits, if you can't help it, then there is only a dead end. Hua An said to Kong Yu.

Kong Yu just nodded after listening to Hua An's words, but didn't say anything, and walked straight towards the huge container in the center. Wealth and danger are sought, since you want to get great power, how can you succeed without enduring danger. And Hua Yue'er watched Kong Yu walk towards the huge container, wanting to open her mouth to stop it, but in the end, she didn't speak.

In the past few days of getting along, Hua Yue'er also knows some things about Kong Yu, and even knows Kong Yu's desire for power, so she knows that even if she stops herself, it is useless, she can only pray in her heart that Kong Yu can be safe, of course, if Kong Yu can get strong power, Hua Yue'er will naturally be happier.

After entering the huge container, Kong Yu stood in it and watched the glass door close. Then I saw that Hua'an took out a remote control again, and after pressing a button on it, suddenly holes appeared from the four walls of the huge container, and in the holes, there were robotic arms stretched out one by one, and on each robotic arm was a long silver needle.

There were a total of three hundred and sixty-five robotic arms, dancing in the huge container, looking at the silver needles that flashed with cold light, Kong Yu was also a little afraid in his heart, and at this time, the container suddenly lost weightless, and his body actually floated involuntarily.

However, at the moment when Kong Yu floated, the three hundred and sixty-five robotic arms pinched the silver needle and inserted it into the acupuncture points around Kong Yu's body, recognizing the acupoints accurately and grasping the strength accurately, just like a miracle doctor who was in the world. It's just that Kong Yu at this time is not grateful to this miracle doctor.

The acupuncture points of the human body are the most wonderful place, and when they reach the peak of the Triple Heaven of Refining and Refining Qi, they can use the true qi in the body to open up the acupoints of the body and absorb the Yuan Qi of heaven and earth for their own use. It's just that ordinary cultivators can only open up part of the acupuncture points of the body, and very few can open up all the acupoints around the body, because this requires too much true qi.

Although acupuncture can treat diseases, it has never been possible to insert silver needles into the acupoints around the body at the same time, because stimulating some of the acupoints of the human body at the same time will bring great harm to people, and Hua'an actually inserted silver needles into the 365 acupoints around Kong Yu's body at the same time.

A piercing pain came towards Kong Yu, Kong Yu wanted to scream, but he couldn't make a sound, and at this time, the five containers filled with liquid around him actually began to inject the liquid in their respective contents into the container where Kong Yu was at the same time, and in the blink of an eye, Kong Yu was overwhelmed by the liquid mixed with the five colors.
