Dai Siyu's face was deathly pale.

She raised her wrist, where a bracelet woven from five different colored threads was tied.

This was a gift from Yang Xiangdi before he left. Yang Xiangdi had told her that this five-colored bracelet was connected to his life force.

Through this five-colored bracelet, Dai Siyu could feel Yang Xiangdi's presence, as if he were always by her side.

But now, this five-colored bracelet was slowly turning gray.

There was only one explanation for this: Yang Xiangdi's life force was rapidly fading.

When the five-colored bracelet completely turned a single shade of gray, it would mean that Yang Xiangdi's life had come to an end.

At this moment, more than eighty percent of the five-colored bracelet had already turned gray.

"No! Yang Xiangdi! You can't do this to me!"

Dai Siyu held the five-colored bracelet, kneeling on the ground, tears streaming down her face, sobbing uncontrollably.

"You promised me, you promised me you would come back, you promised me that as long as you came back, we would have two cute babies together, and then find a secluded place to live a life away from the world!"

"You lied to me, Yang Xiangdi, you're a big liar! You lied to me!"

Dai Siyu cried out hysterically, unable to accept the fact that Yang Xiangdi was dead.

Her mournful cries seemed to cross the endless void, reaching the underworld.

Yang Xiangdi, who was lying on the ground, seemed to twitch his finger.

"Heh... slowly enjoy the pain of being corroded to death by death and silence, ant."

Thanatos's cold face was expressionless. This human was obviously doomed to die. He was going to chase after Qiao Yu and Ma Fei.

He absolutely couldn't let these two enter the Underworld God's Palace, otherwise, it would be his, Thanatos's, dereliction of duty.

The broad wings on his back spread out, and the space in front of Thanatos shattered. He was going to cross the void and directly block Qiao Yu and Ma Fei's path.

But just then, Thanatos found that his outstretched wings couldn't move.

"What is this?!"

Thanatos's silver eyes narrowed sharply, filled with disbelief.

His wings were covered in frost, and then a layer of ice condensed on the surface of his wings, freezing them directly!

Yang Xiangdi, behind him, stood up unsteadily, his body still rotting, muttering to himself.

"Senior... how could I bear to lie to you... the flushed face in the depths of the night, the love overflowing from the depths of my body, the quilt becoming our protective shell, us shedding all our defenses and revealing a side rarely seen."

"Invasion, possession, conquest, hands clasped tightly, hair soaked with sweat, running and chasing, that night we were each other's soulmates, the endless night was proof of our deep love."

"The person I love is still waiting for me to return... how could I... fall in a place like this!"

Yang Xiangdi raised his eyes, his eyes were bloodshot, filled with fierce light.

He had never been an easy-going, kind person. It was only when he was with Qiao Yu and Ma Fei that Yang Xiangdi had been restraining the thorns on his body.

"A final burst of energy before death? Humans are truly uninteresting."

Thanatos turned his head coldly.

"Since you're in such a hurry to die, then I'll grant your wish."

Thanatos raised his hand and clenched it, and black death energy swept over. Such a huge death energy would definitely annihilate Yang Xiangdi directly in an instant.

However, just as the black energy swept in front of Yang Xiangdi, it suddenly stopped completely, unable to advance even an inch.

"What?!" Thanatos's face changed drastically.

And Yang Xiangdi's body was still rotting, but there was an inexplicable and strange energy on his hands.

"Thanatos, you're known as the God of Death, right? Then do you know how black holes in the infinite universe are formed?"

Yang Xiangdi's voice was devoid of emotion, like a machine.

"I don't understand what you're talking about! But all I know is that you're going to die!"

Thanatos roared, and even more violent death energy surged out of his body, heading straight for Yang Xiangdi.

Yang Xiangdi's tattered body was like a small boat in a stormy sea under the impact of this death energy, and could be overturned by the huge waves at any time.

However, Yang Xiangdi was not panicked at all, and just muttered to himself.

"A black hole is not actually a hole, or a passage, but a dense celestial body with infinitely small volume and infinitely large gravity. It is something whose space-time curvature is so large that even light cannot escape from its event horizon."

"Any object with mass has a radius threshold, called the Schwarzschild radius. When an object is compressed to this critical radius, a black hole is produced."

"The existing cosmic black holes are all formed by supernova explosions when stars die. When a star exhausts all available nuclear fuel, it will collapse into an extremely dense celestial body, which is a black hole."

As soon as he finished speaking, a terrifying explosion suddenly occurred in Yang Xiangdi's palms. His hands disappeared, and even the light disappeared from the place where his hands were. Only the purest darkness remained.

Yang Xiangdi slowly raised his eyes, his eyes full of indifference.

"In other words, a black hole is the product of a supernova's death. So Thanatos, do you know what happens when two black holes with infinite gravity collide and merge with each other?"

In Thanatos's horrified gaze, Yang Xiangdi slammed his armless arms together.

"Let me tell you! Two black holes will rotate and collide at extremely high speeds! And in the process of collision, the energy generated will cause the surrounding gas and dust to be rapidly heated and rotated, releasing a large amount of energy and high-energy particles!"

"In this way, the strongest burst phenomenon in the universe can be produced! Gamma-ray burst!"

Yang Xiangdi roared, and energy that was violent to the extreme spewed out from the darkness in his palms.

"The energy produced by a single gamma-ray burst is equivalent to the total energy of a trillion years of sunlight!"

"The energy released by the sun in ten billion years can be released by a gamma-ray burst in just one second."

"Any creature within the range of the gamma-ray burst's shockwave will be formatted. Because the principle of gamma rays killing creatures is that high-energy particles disperse the atoms of the creature itself. Therefore, whether it is a carbon-based creature or a silicon-based creature, as long as it is an object composed of atoms, it is impossible to resist a gamma-ray burst."

"So now... God of Death, Thanatos, answer me! Can a god... withstand a gamma-ray burst?"
