With the headphones on, all sound disappears completely.

The shielding effect is amazing, Li He thought, and when the matter is over, he will detain the earbuds as payment, and it will not be too comfortable to use at night when he sleeps.

Qin Yunchen stood in front of a huge instrument, his fingers were quickly operated, and Li He was close to him, his eyes sweeping around the laboratory.

Symbols that Li He couldn't understand quickly danced on the screen of the instrument, and after about ten minutes, Qin Yunchen began to tremble, shaking more and more violently, as if he had heard something, his face turned pale, and his pupils began to become dilated.

Li He straightened up, his brows furrowed tightly, and the characters on the instrument screen jumped even faster, and the progress bar at the bottom was only halfway through.

He stretched out his hand to support the crumbling Qin Yunchen, and suddenly saw blood on the corner of her lips, as well as the familiar smell of blood gradually spreading in the air.

Li He's eyes widened in disbelief.

In his sluggish interval, Qin Yunchen shook his head fiercely, tried to regain his senses, and grabbed Li He's hand and bit it fiercely.

The huge pain from the tiger's mouth finally brought Li He back to his senses, and he watched as the young man grabbed his hand and bit it and sucked it.

Li He snorted, has this become a vampire!

At this moment, he finally realized that Qin Yunchen had been beating him with the idea of blood!

I don't know what the reason is, maybe it was because he suddenly discovered Qin Yunchen's identity, Li He didn't immediately withdraw his hand, and let Qin Yunchen do whatever he wanted with a calm face, the pain from his hand made the corners of his lips twitch, and his face became darker and darker.

I never dreamed that one day I would be sucked like this.

The moment he sucked Li He's blood, Qin Yunchen gradually came to his senses, and the sound in his ears could no longer affect his sanity.

He smiled lightly, and sure enough, as he expected, Li He's blood could break the mental attack on him from these sound waves.

After the palm of his hand was released, Li He grinned at his wound, and he took off his earbuds viciously.

Just as he was about to question, his ears were filled with a sharp, familiar chirp.

Li He's face sank suddenly, and his eyes narrowed.

Qin Yunchen began to continue the operation again, and soon, the progress bar was full, he took out the memory card from the instrument, and in a blink of an eye, he saw that Li He had removed the earbuds and was staring at him with death.

Qin Yunchen was nervous for a moment, and reacted quickly in the next second, Li He was completely unaffected by these voices.

After a little thought, he was relieved.

After all, Li He's blood could make him immune to sonic attacks, and he himself would definitely be completely immune to these sound waves.

The young man was a little out of strength and patted Li He's shoulder, "Let's go." ”

His voice became deep and there was a slurred feeling.

Li He followed closely behind him, surprised, "You bite your tongue?" ”

Qin Yunchen opened his mouth, and another stream of blood flowed out, and it seemed that the bite was not light.

"The pain can bring me to my senses."

Li He pursed his lips and said nothing, followed behind Qin Yunchen, the two came out of the secret passage, closed the entrance of the mechanism, and as soon as they walked out of the ancient castle, they met Li Jiu and Shi Dusk.

The four of them all paused, and Li He stared at Shi Du with unkind eyes, what's the matter with this kid? It's always ghostly!

Li Jiu wrinkled his nose and inhaled hard the faint smell in the air, the fishy sweet familiarity.
