The night in the forest is quiet and a little terrifying, the towering tree trunks crisscross the sky, and the cold moonlight is dappled towards the castle through the rich foliage gaps, and the sparkling light is even more mysterious and deep at this moment.

"There's no movement over there, is there?" Mu Zichen's dark eyes were deep and complex, and his extremely cold voice came out low.

"No, my subordinates have been paying close attention to them, please rest assured." Black Wind replied without dragging his feet in the slightest.

"Stare to death. In addition, the rose garden will send more people to ensure the safety of Tianyang and the little woman. Mu Zichen repeatedly confirmed that if he wasn't afraid that he would hurt him, he really wanted to put the little woman in his pocket and keep it with him all the time.

"The young master is back." When Mondstadt saw the group, he hurried up to greet them and saluted respectfully, and then followed behind Mu Zichen, ready to be sent at any time.

Mu Zichen didn't pay attention to him, his forehead had already started to have a faint headache, and he clearly knew that this meant that the damn Gu poison was going to start making trouble again.

He quickened his steps into the chamber on the second floor, closed the door, isolated everyone who was with him, and quickly locked it.

He didn't know if he could withstand the devastating devouring alone, in the past, Xiao Mo and them were by his side, giving him a specially developed tranquilizer when he couldn't stand the erosion and even self-harm.

However, this time, he wanted to try to face it alone. Because, it is impossible for others to accompany him forever, and if he is worried about the time he is bumped into by that little woman, will she be scared? Therefore, this time, he wanted to test whether his self-control could control the Gu that penetrated deep into the bone marrow.

Mu Zichen didn't know what kind of poison he would face this time. I don't know how the old witch developed this kind of ruthless upgrade Gu, from the moment of the Gu to the present for more than ten years, every attack will have different symptoms, the old witch seems to want him to taste all the pain of this time, she hates herself for going deep into the bone marrow, but she doesn't let herself die easily.

The pain in his forehead had become more and more intense, irritating every nerve in him. Beads of sweat the size of beans came out in fine and dense manners, dripping on his bloodless pale face.

He gritted his teeth and insisted, as if he was angry, not saying a word, silently thinking in his heart that he must defeat this damn Gu.

However, a sharp pain came over him like a wave, almost drowning him. He felt like countless worms in his body were tearing at every inch of his skin, sucking every drop of his blood, and waves of never-ending pain hit him.

His deep dark eyes turned bloodthirsty scarlet at the moment, his thick eyebrows were tightly twisted, and his handsome and carved facial features were deformed from unbearable pain.

Suddenly, he felt a cramping pain in his heart, like thousands of ants devouring his heart. He rolled on the ground in pain, and his neatly trimmed nails quickly grew sharp nails 5 centimeters long, which were more like minions than nails, which were as sharp as wolves.

Mu Zichen's sharp nails cut against the wall, and everywhere he went, there were shocking ravines.

This secret room is specially made of high-precision tank materials, fireproof, waterproof and explosion-proof, with strong secrecy, even the sound is completely isolated, and people outside do not want to forcibly enter. Therefore, even if Xiao Mo and the others wanted to go in, they were more than willing to do it, so they could only do it in a hurry.

There was no light in the secret room, it was pitch black, and he could only see Mu Zichen's scarlet eyes with a fierce light turning slightly, and his body was as wet as washing, he felt that his heart had been completely devoured by those insects and ants, and slowly followed his limbs, at this moment he was like a human being, those insects still did not intend to let him go, and continued to bite his flesh and blood one by one, before the whole body disappeared, he let out a miserable long howl, resounding throughout the forest.
