On this day, Zhang Jun and Long Qun were leisurely basking in the sun on the grass in front of their house, it was spring, everything was prosperous, and the surrounding was a green and vibrant scene, and the warm sun shone on the body, which was very comfortable.

Zhang Jun was lying near the entrance of the cave, closing his eyes and recuperating, the three King Kongs were lying on their stomachs not far away, as if they were chatting about something, the two great Dharma Protectors and Fei Ge were resting on the other side, and some small dragons were running and frolicking around, everything seemed to be so harmonious and harmonious.

And just a few minutes later, a huge sound suddenly sounded in the northern sky, from Zhang Jun's position, this huge sound could not be heard, but the animals located in the northern hemisphere, especially near ancient China, heard this terrifying loud sound.

After this loud noise, Zhang Jun felt the surface tremble slightly, he didn't care, because every time there is an earthquake in the distance, or a natural phenomenon such as a volcanic eruption, the ground will tremble, and generally there will be no serious consequences.

But this time it was not an ordinary event, the center of the explosion was not located in another place, but happened to be located in the space-time temple where Zhang Jun had been, that is, the independent cabin of the spaceship where the Blue Scorpion Prince was located, Zhang Jun's guess that the planet hit the earth did not happen, but the explosion was the independent cabin that had already activated the self-explosion system.

Zhang Jun didn't expect the explosion time of the independence cabin to be set tens of millions of years later, and he couldn't feel the huge shock wave caused by the explosion.

On the valley above the independence module, a huge mushroom cloud rose into the sky, and a huge explosion immediately dismembered the various spaces of the independence cabin, and many various items in the independent space flew out. This mushroom cloud did not disappear quickly, but quickly spread to an area of about 100 kilometers around, and the explosion energy of the independence module was equivalent to 10 billion Hiroshima atomic bombs, which immediately blew out a crater with a diameter of up to 200 kilometers in the ground.

The flora and fauna within a hundred kilometers of the center of the explosion quickly turned into nothing, and their bodies were all immersed in a huge shock wave, and the huge energy turned the soil on the earth into dust, and a large dark dust began to spread with the air current.

Soon, the surrounding sky within a radius of nearly 1,000 kilometers was gradually covered with dust, and the boundaries of the dust were expanding, spreading to the whole world, and countless animals screamed and died in the fire and shock waves, and when the dust fell all over the sky, most of the animals let out a cry of fear, because they gradually could no longer see the sun, the sky became very gloomy, and the light was very weak, and this state of affairs continued without the slightest change for a few days.

The animals began to run and roar in the jungle, they tried to run out of this terrifying dust area, but no matter how hard they tried, they could not find the edge of the dust, but they still struggled to run, and the jungle was chaotic, and countless animal figures shuttled everywhere, and the cries kept coming.

About two months later, one day, Zhang Jun suddenly heard a huge sound of hooves and feet, coming from the far north, and he asked the other dinosaurs to go to a commanding height to observe, and found that the world had changed greatly.

A great male dragon ran back in a panic and said to Zhang Jun: "Chief, the northern sky is shrouded in a huge cloud of dust, and the dust is drifting towards us, and it seems that it will soon be here, what should we do." ”

"And there are countless animals running towards the vicinity of the dragon's den, so many animals, we can't stop them." The male dragon was out of breath, and then said a little hurriedly.

Zhang Jun immediately stood up from the ground, he seemed to feel something unusual, and sighed in his heart: "Could it be that the tremor that happened two months ago was the day of the catastrophe?" ”

Zhang Jun didn't know what the cause of this disaster was, because he was not at the center of the disaster, and if he wanted to find out, he could only observe it later, so he immediately needed to make a judgment on whether this time it was a global catastrophe.

"Let's go, take me to see it." Zhang Jun didn't dare to slack off, and immediately let the male dragon lead the way, and ran towards a mountain with it.

When he arrived at a high ground, Zhang Jun found that the bald ones had already stayed there, they all let out a cry of surprise, and were talking about something in a panic, he immediately looked over, and saw that the sky in front of him was covered with dust, a dusk, and the dust was drifting towards this side, and it should be possible to reach here in one day, and the entire sky in front of him was obscured, without any exception.

"Chief, what's going on?" Qili stood beside Zhang Jun, and then asked in great surprise.

Zhang Jun shook his head and said, "I think this is the beginning of a mass extinction, and we need to hide in the underground dragon's den for a while to survive this disaster safely." ”

The bald head immediately approached and said suspiciously: "Underground Dragon's Nest, it turns out that the leader is preparing to deal with this incident, and it seems that the leader has already prepared." ”

"I'm just surmising it based on what the Blue Scorpion Prince and the Demon Spirit said back then, and they all warned me that this catastrophe was coming sooner or later, and I had been waiting for this day to come."

"I see, can we survive this disaster, we won't all die here, right?" The big Al on the side had already panicked and ran over to ask.

The other dinosaurs were staring at Zhang Jun's face to see if he had any solutions, and then Zhang Jun said unhurriedly: "Don't worry, the Blue Scorpion Prince once gave me a potion that can help us get through the period of mass extinction." ”

"Haha, that's great, I just said we won't die here, I have to live for 100 million years." Little Al followed suit.

"So now one thing, I must tell you, if this disaster lasts for more than half a month, we must take medicine, enter a state of suspended animation, and then stay underground for two hundred years before coming out, I think by then, this dust should have been purified." Zhang Jun then explained.

"Two hundred years, oh my God, will we still be alive then?" An old dragon let out an exclamation in disbelief.

Zhang Jun then explained a little to them, so that they understood the general situation, and they understood the mystery, and then followed Zhang Jun down the mountain, ready to enter the underground dragon's nest, and they also prepared some spare food, brought into the dragon's nest, at least for more than a week.

The remnants of the explosion of the Independence Module have not been preserved, but have been washed away by the years, so later scientists did not find that there were factors that caused the fifth mass extinction in ancient China, but this is the case, the fifth mass extinction was caused by the explosion of the Independence Module.
