Old Man Xiao waved his hands and removed the clothes on his body one by one.

Chen Feng looked and could not help but secretly nod his head: "Looks like this Old Man Xiao was also a good person when he was young. The speed at which he took off his clothes was as fast as lightning."

All he wanted to do was think about it. Chen Feng's hand was not slow. The Zhen Qi long needle in his hand drew a dazzling arc in the air, and then deeply pierced into the acupoint on Old Man Xiao's chest!

Old Man Xiao's eyes widened as he grabbed the carpet on the ground to shatter it. The intense pain made sweat drop down like rain on his face. The veins on his forehead were like horned dragons, seeming as if they would break open his skin in the next moment and fly up into the air.

"AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!" Old Man Xiao couldn't help but let out a low howl, trying to ease the enormous pain.

Old Man Xiao was a truly ferocious person. Even under such pain, his body actually remained motionless.

A hint of admiration appeared in Chen Feng's eyes as he reminded him in a low voice, "I need four needles in total. Each needle is ten times more painful than the previous ones." You can choose to faint, but if you maintain your consciousness until the end, it will be of great benefit to you! "

A trace of determination flashed across Old Man Xiao's eyes: "Sir, do your best."

Chen Feng nodded and another true energy long needle condensed between his fingers.

"Rumble …"

The zhen qi long needle actually let out a light hum. From this, it could be seen how powerful the energy contained within this needle was.

Without the slightest hesitation, Chen Feng pierced this needle heavily into Old Man Xiao's Tianshu acupoint.

"Ugh!" The intense pain instantly caused Old Man Xiao's body to bend forward involuntarily. The muscles all over his body suddenly trembled, like a lobster that was about to be cooked.

"The third needle is ready!" Chen Feng suddenly shouted and another long needle made its move. It silently inserted itself into the xuanji acupoint.

"Roaaaaaar!"

Old Man Xiao's mouth instantly gaped wide open as he let out a huge roar. Powerful zhenqi burst forth, shaking and scattering all the decorations in the surroundings.

However, even though it was incomparably painful, Old Man Xiao still clenched his teeth, preventing himself from fainting. He knew that Chen Feng definitely had his reasons for speaking. Perhaps, this was a rare opportunity for him.

"The last needle has been blocked!" Chen Feng let out a long whistle as a true energy long needle in his hand slowly pierced into Old Man Xiao's temple.

This time, it didn't pierce him, but slowly like a normal acupuncture needle.

"Hrm …"

Old Man Xiao's fur immediately shot up into the sky. This enormous pain caused his consciousness to blur. His eyelids slowly drooped down.

"Sigh, looks like I still haven't been able to last until the end." Chen Feng sighed lightly. "If we can hold on for another moment, the benefits will be incalculable."

Old Man Xiao's eyelids, which were about to close, suddenly stopped. Following that, an angry roar sounded out from the depths of his throat: "I definitely can't faint, I have to persevere!"

As his words fell, Old Man Xiao's body abruptly straightened.

"What a strong willpower!" Chen Feng's heart shuddered and his eyes were filled with praise. Old Man Xiao's willpower was definitely one of the few in the world.

"It's a pity that Old Man Xiao is already old. Otherwise, I might have once again fallen in love with him and take him as my disciple." Chen Feng looked at the Xiao family's old patriarch, who was struggling to hold on, and thought to himself.

"Hahaha, this is great! This is great!" Amidst the incomparable pain, Old Man Xiao suddenly laughed out loudly. Borrowing this unrestrained laughter, Old Man Xiao's aura increased a bit more.

Chen Feng's fingers were still pinching the Zhen Qi long needle, as if no matter how Old Man Xiao moved, his hand would not tremble.

The long needle slowly pierced into Old Man Xiao's temple, causing his pain to become more and more severe. The carpet on the floor had been torn to shreds. His hands had even dug deep into the floor, leaving behind small, dark holes.

Finally, Chen Feng's hand abruptly stopped.

"Weng —" The four long needles began to vibrate at the same time, as if there was some sort of connection between them.

Suddenly, Old Man Xiao felt a wave of nausea and spat out a mouthful of black blood.

"Hiss —"

Immediately, a large hole appeared in the ground due to the corrosion of the black blood. There were traces of green smoke coming out from the hole. A foul smell accompanied the green smoke as it entered the two people's nostrils.

"I never thought that the energy in my body would be so powerful. However, it has finally been expelled by my body along with this mouthful of black blood. "Un, it's so comfortable." After spitting out this mouthful of black blood, Old Man Xiao felt an indescribable happiness in his heart and lungs. The pent-up anger that had been bottled up in his chest for so many years immediately dissipated.

"Seize this opportunity and focus on calming your breathing!" Old Man Xiao was about to enjoy this comfortable feeling when Chen Feng's voice sounded like thunder.

Old Man Xiao's heart trembled. He no longer cared about enjoying this comfortable feeling and immediately calmed down.

Old Man Xiao, who had just calmed down, instantly felt an unusual sensation.

"This feeling?" Old Man Xiao carefully experienced this feeling and felt that it was an incredibly profound aura, but he was unable to grasp it.

Suddenly, Old Man Xiao's heart shook violently. Chen Feng's words were like a bright lamp in the darkness, allowing him to instantly see the road ahead.

"Will?" The Xiao family's old patriarch felt his heart tremble as a thunderclap sounded out in his mind.

"This is …" Perception? " Old Man Xiao's heart thumped. Just now, Old Man Xiao, who had his eyes closed, had actually seen everything around him.

"Sensory Perception, isn't that an ability that only True Essence realm cultivators have? Why can I, who is only at the sixth level of True Qi, have the ability of perceiving?" A flash of understanding appeared in the Xiao family's old patriarch's heart: "Could it be that what Mister Chen said is beneficial is just this?"

He was extremely grateful, but Old Man Xiao also understood that this was not the time to express his gratitude. He immediately put down all of his thoughts to carefully experience this feeling.

Seeing the Old Master Xiao close his eyes without moving, Chen Feng knew that Old Man Xiao had already entered a state of enlightenment. When he completely grasped the 'Perception' ability, Old Man Xiao's strength would advance by leaps and bounds. Even if it was the True Essence realm that martial artists dreamed of, he could still try to break through it.

Lightly opening the door, Chen Feng walked out of the study and headed outside. Old Man Xiao's injuries had already healed. He didn't need to do the rest.

"Wuuuuuu ~ ~ ~"

"Hmm?" After walking a few steps, Chen Feng heard the unique melody of the flute, making him fall into deep thought.

"I must have heard this flute melody somewhere before!" Chen Feng thought to himself as he walked in the direction of the flute.
