"You're going to test the fifth level now?"

"Yes!" Feng Shino replied respectfully.

"There's a teleportation array not far ahead, you can go in directly! Bendi is waiting for you at the fifth level! ”

Feng Xiao walked towards the front of the martial arts arena, and sure enough, he saw a small teleportation array in operation, and walked in without hesitation.

When his feet landed again, he found that there was a hundred-meter-square pool in front of him, which was filled with a black liquid like oil, bubbling at the moment, and there was a faint trace of bloody qi flowing between his nose, and these bloody gases carried a strong spiritual power.

"Your task in this level is to enter the Wuchi and open up the one hundred and eight meridians in the body and the acupuncture points that connect them." The voice came, and then a book of exercises appeared in the air, and Feng Xiaoyou reached out to take it.

"When you do that, you'll get out of here!" The voice added.

Feng Xiaoyou sat on the edge of the pool and opened the book with the book, it turned out that this was not an exercise, but a booklet that recorded the methods and rules of opening the acupoints, and now Feng Xiaoyou already knew that the liquid in the black pool in front of him was refined by the blood night of the ancient demon Iron and hundreds of precious elixirs, which contained great power.

What Feng Xiaoyou has to do now is to sit in this black pond and cultivate, of course, this is different from the usual cultivation, she must sink her divine consciousness into her body and guide the spiritual power containing the tyrannical qi of iron into her body to impact the tendons and veins in her body.

Now that he understands, Feng Xiaoyou no longer hesitates, puts away the glass clothes on his body, and jumps into Wuchi wearing only a shirt, the liquid in Wuchi is a little hot, Feng Xiaoyou gritted his teeth and endured, and found a position to the side and sat down cross-legged. Running the "Chaos Heavenly Formula", first breathing, and then slowly guiding the tyrannical spiritual power in the blood pool into his body, when these spiritual powers entered the tendons, Feng Xiaoyou felt a faint pain, but it was still within the range of tolerance, she first guided this spiritual power to be contained in the body for a week, and after getting used to it, she absorbed an appropriate amount of spiritual power from the black pool into her body again, and so on and on, when the spiritual power of the spiritual power reached saturation, and the tendons and veins were unbearable, she rushed towards the nearest acupoint, Just for a moment, Feng Xiaoyou felt the pain in her heart, this pain made her body shake a few times, and her forehead was oozing sweat, Feng Xiaoyou stabilized her mind, and continued to impact towards this acupoint, after ten impacts, the spiritual power in the tendons and veins finally passed through the acupoint like a flood, and entered the tendons and veins that had just been opened. At this time, blood was oozing from her mouth under the wind, not because of an injury on the inside, but because she had bitten her lip because of the pain.

In this way, Feng Xiaoyou stayed in this black pond for eighty-eight days, and finally opened all the acupoints, at this time she looked a lot clearer, and her beautiful big eyes became a little bigger.

Feng Xiaoyou tried her best to climb from the black pond to the shore, yes, she climbed to the shore, at this time she was already a little out of strength, and her spirit was extremely tired, she couldn't care about anything else, so she lay on the edge of the pool and fell asleep.

It was already three 'days' after Feng Xiaoyou woke up again, she slowly got up from the ground, took out a liner from the storage bag, found a hidden place to change the underwear that had turned jet black on her body, and took out the glass coat to wear outside.

This time, Feng Xiaoyou gained a lot, and the liquid in the black pond was transforming her muscles and veins while also improving her cultivation, and now her cultivation had reached the early stage of the twelfth layer of Qi training.
