Before he finished speaking, Yu Bai had already squatted down beside the bed.

She stretched out her hand, trembling, but firmly holding Yu Cheng's cold hand with the IV tube inserted.

With this seemingly ordinary grip, she quietly placed the crystal core that had been clenched in her other hand on the inside of Yu Cheng's wrist, where the skin was thinnest and most easily absorbed.

A warm and powerful energy, like a trickle of water or a raging underground river, silently flowed towards Yu Cheng's exhausted body.

Almost at the moment when the crystal core touched the skin, Yu Cheng's body, which was as silent as a broken machine, suddenly became like dry firewood thrown into sparks.

Every inch of flesh and blood, every cell, instinctively woke up, madly and greedily absorbing this life-saving energy!

Yu Bai could clearly feel that the pigeon egg-sized crystal core in his palm was rapidly dimming and shrinking at a speed visible to the naked eye.

At the same time, a strange tingling sensation came from the place where the two people were connected. It was a sign that the bones were connecting quickly, the flesh and blood were growing rapidly, and the organs were repairing themselves frantically!

However, in just a few breaths, the energy of the crystal core was exhausted and turned into nothing.

At this moment, Yu Cheng, who was originally lifeless on the hospital bed, suddenly trembled his eyelashes a few times, and then, the pair of eyes that had been closed for a long time slowly opened!

"Fourth brother!"

Yu Bai was surprised and happy, almost jumping up and calling for a doctor.

However, Yu Cheng held her tightly and looked at her with clear eyes and a hint of unquestionable restraint.

Others may not know, but Yu Cheng himself knows it very well.

He seemed to be in a deep coma and his body functions were on the verge of collapse, but his consciousness was like a ghost, always lingering clearly in the depths of his mind.

From the excruciating pain of falling, to being sent to the hospital, to the cold instruments in the operating room, to his sister's anxious calls, to Li Zhenguo's guilty explanation...

He "heard" all of this clearly and "saw" it all clearly.

Therefore, when his sister's familiar and warm crystal core energy touched his skin, he mobilized all his remaining willpower almost without hesitation, actively guiding it and madly absorbing it!

He woke up and even felt better than ever.

The broken bones have healed perfectly and the damage to the internal organs has disappeared without a trace.

But he couldn't show it!

A seriously injured person miraculously recovered in just a few minutes without any special medical intervention?

How can this be explained? The secret of the crystal core must not be revealed!

That's why Yu Cheng stopped Yu Bai.

Yu Bai also realized his impulsiveness in an instant and immediately stopped all actions.

Although Yu Bai tried his best to restrain himself, the suppressed "Fourth Brother" was like a stone thrown into a calm lake, causing ripples outside the silent intensive care unit.

Li Zhenguo was so sensitive that he caught the movement almost instantly.

"Yu Bai, what happened?"

He saw Yu Bai squatting beside the bed, holding Yu Cheng's hand, with an excited expression on his face.

Yu Bai's heart skipped a beat and he thought to himself, "Oh no!", but he didn't dare show it on his face.

She quickly adjusted her expression, meeting Li Zhenguo's gaze with a bit of surprise, a bit of uncertainty, and just the right amount of eagerness.

"I... I just thought I saw my fourth brother's eyelids... move! Is he about to wake up?"

This is half true and half false.

The eyelids did move and the person did wake up, but it was definitely not as simple as "about to wake up."

Upon hearing this, Li Zhenguo was stunned at first, then he leaned over and carefully observed Yu Cheng lying on the hospital bed for a moment.

Seeing that his eyes were still closed and his breathing was steady, his face seemed a little redder than before - this was probably the initial effect of the nourishment from the crystal core energy, but outsiders would only think it was a blood transfusion or the effect of the drug.

He understood it clearly.

This girl must have been too worried and her eyes were blurry.

Well, who wouldn't be terribly anxious when a loved one is seriously injured and dying? It's normal to have some hallucinations.

He turned and looked at Yu Bai: "Comrade Xiao Yu, I know you're worried about your fourth brother. But his injuries are extremely serious, and he just underwent major surgery. The anesthetic effect hasn't completely worn off yet. It's impossible for him to wake up so soon."

These words are both an explanation and a comfort.

How could a person who had just been pulled back from the brink of death wake up in just a few minutes?

There is no medical explanation.

"But don't worry."

Li Zhenguo saw the light in Yu Bai's eyes dim and quickly added.

"The doctor said the operation was a complete success, and your fourth brother's physical condition is surprisingly good. Rest well, and he should be able to wake up tomorrow morning."

He paused and continued:

"This is an intensive care unit with strict supervision and limited visiting hours."

"You shouldn't stay too long, as this will disturb the patient's rest and increase the risk of cross-infection. Go back and have a good rest, and come back to see him tomorrow."

Yu Bai knew clearly in his mind that what Li Zhenguo said was true, and he also knew the reason why his fourth brother could not "wake up" at this moment.

She was grateful for Li Zhenguo's understanding and followed his instructions.

She uttered a soft "hmm," with a barely perceptible sob and deep sense of loss in her voice, as if the hope that had just been ignited had been ruthlessly extinguished.

She looked at Yu Cheng reluctantly again, then stood up.

Just as Li Zhenguo turned around and motioned her to leave, Yu Bai quickly took out another crystal core from his pocket.

With the cover of the quilt and her body, she quickly and gently stuffed the crystal core into Yu Cheng's slightly cool palm.

This subtle movement was so fast as lightning that even Li Zhenguo, who had been paying attention to her, did not notice it.

One more crystal core means one more protection.

Although Fourth Brother has regained consciousness, his recovery still requires a huge amount of energy.

She couldn't stay here all the time, so she could only help him as much as possible in this way.

After doing all this, she took a deep breath, with just the right amount of fatigue and resignation on her face, and followed Li Zhenguo out of the intensive care unit.

In the ward, Yu Cheng was still "unconscious".

But the hand that was stuffed into the crystal core by the sister tightened slightly under the quilt without anyone noticing, firmly grasping the heavy love and strength.

And he will definitely use his own way to protect this family and his sister, to whom he owes so much!
