Dragon's Origin

In this world, people study various elixirs and possess rudimentary chemistry, but they lack large-scale, systematic research. Therefore, many people, including these single-minded masters, masters of masters, are completely unaware of something called biogas.

For people on Earth, anyone who has taken high school chemistry knows what methane is. Nature has abundant methane, much of which forms in environments like this valley.

It's called biogas because, in a natural environment, these methane gases form in swamps. However, in many cases, naturally generated methane, if not diffused, mostly remains at the bottom of the water or the mud.

This valley was carefully chosen by Wang Sheng. He didn't waste the time waiting for the various family masters to arrive; he finally found such a uniquely advantageous place.

The small holes poked in the ground and in the water with wooden sticks were, in the eyes of the world's masters chasing after him, traces left by Wang Sheng as he probed the swamp after falling into it. But Wang Sheng knew very well that those small holes were actually guiding the biogas from underground.

This valley was not a well-ventilated valley to begin with, making it particularly suitable for methane formation. The air usually contained a considerable amount of methane. Mixed with the smell of decaying leaves and such, the people of this world generally mistook it for miasma.

The methane that Wang Sheng had extracted from underground quickly mixed into the air. In Wang Sheng's judgment, it had long exceeded the explosion limit. With just a spark, it could trigger an explosion of the entire valley.

The gas in the valley was definitely poisonous, but that didn't stump Wang Sheng. Wang Sheng's rigid nose and mouth guard could perfectly solve this problem. The activated carbon filter layer could absorb most of the poisonous gases. In addition, there were two compressed air tanks. Wang Sheng had only used them a few times, and there was still a lot of compressed air left, enough for Wang Sheng to stay safely in the valley.

Watching those chasing masters fall into his trap, Wang Sheng felt a little regret. There were still three to four hundred people left outside who hadn't followed in. Otherwise, that would have been the most perfect ending.

After rushing out of the valley, Wang Sheng opened the fire striker. It was a fire-starting tool in this world. The small bamboo tube contained some kind of burning grass leaves that could last for a long time. As long as you blew on it, a flame would appear.

Throwing out the fire striker, Wang Sheng didn't dare to linger. He ran as far as he could, anyway, he had already made a turn, and he wouldn't bear the direct impact of the explosion.

The Qiu family master who was chasing closest was less than a hundred meters away from the valley entrance. He saw the fire striker draw a perfect arc from afar and fly into the valley.

Boom, before the fire striker landed, a blue flame ignited in a certain place, and then the entire valley turned into a huge bomb, exploding with a bang.

What a terrifying scene it was when a huge valley, about several miles long, more than a mile wide, and nearly a mile deep, filled with methane and countless explosive gases, suddenly exploded?

The entire ground in this area shook violently several times as if hit by a giant hammer. The power of the explosion was almost comparable to a small earthquake. A mushroom cloud rose slowly from the center of the valley, quickly spreading into a smoke column of several thousand meters.

The temperature in the most concentrated area of gas in the center of the valley instantly reached thousands of degrees. The hundred or so chasing masters in that area didn't even make a sound before turning into coke.

Whether they were fifth-level masters or second-level or third-level followers, the result was the same. In the face of such explosive power comparable to the might of heaven, even the strongest master was just scum.

The edge of the area was a little better, but only a little. The chasing masters distributed in this area flew up neatly like being hit by a baseball.

In these masters' average of more than a hundred life-and-death struggles, the experience of having their bodies knocked so far was probably less than once per person on average. But this last time took the lives of most of them.

The damage caused by the violent explosion definitely exceeded the full attack of the strongest master among them. While still in the air, 70% of the masters vomited blood and died.

Those who could survive under this kind of explosive power were all top masters, at the very least in the late stage of the fourth level, who could protect their bodies with a mouthful of spiritual energy, so as not to be immediately blown to death by the explosion.

But even so, it didn't mean they had a chance to survive. Everyone in the valley was holding their breath, for fear of inhaling too much poisonous gas and miasma. Later, when Wang Sheng fled, everyone chased frantically, and their breathing became rapid, involuntarily inhaling a lot of poisonous gas and methane.

Precisely because of this, some explosions and combustions occurred inside their bodies, right in everyone's respiratory system. In other words, even if they survived that level of explosion, everyone's respiratory system inevitably suffered injuries to varying degrees.

Being blown away and thrown heavily to the ground was another injury. This level of attack was enough to shake the internal organs of these top masters, causing them to vomit blood and get injured. But that wasn't the end of it.

The sudden explosion of an entire valley was simply the explosive power of a large fuel-air explosive. After the explosion, the air around the valley within a few miles was immediately consumed by the violent combustion.

This was originally a valley that was not well-ventilated and not conducive to diffusion. This time, everyone inside and outside the valley faced a catastrophe: lack of oxygen.

If they were not injured and held their breath in time, with everyone's cultivation, they could definitely reduce oxygen consumption and hold on until fresh air diffused over. The problem was that the survivors in the valley were not only seriously injured, but also breathing rapidly before, and their respiratory systems were also damaged by the combustion.

The few strongest masters who had managed to survive died one by one in agony from suffocation under these desperate circumstances.

When the masters watching outside the valley exploded, at least thirty of them facing the valley entrance were affected by the explosion wave inside the valley and flew out a long way. Less than half of them could crawl up.

Those masters who did not directly feel the power of the explosion looked in horror at everything that was happening before them. No one could believe that in just a moment, the entire valley had turned into a dead valley.

How was this possible? There were at least ten fifth-level masters inside, dozens of fourth-level masters, and the rest were all third-level and second-level masters. How could they all die in an instant?

Some people were not dead, and the people outside saw it too. But they were now unable to attend to their own needs. Suddenly, they couldn't breathe. Where did they have the strength to take care of others?

Everyone held their breath, and no one dared to act rashly. They could only watch helplessly as the few surviving figures in the valley struggled, each clutching at their throats, unable to even scream in pain, and slowly died after struggling for a while.

That scene was so terrifying that every master who saw it felt as if they had fallen into an ice cellar, their whole body was cold. More than half of the people didn't realize that their bodies were trembling, and their upper and lower rows of teeth were constantly clattering, making a rattling sound.

The contempt when they received the pursuit order, the surprise when they chased here, the horror of discovering that Wang Sheng had entered the Thousand Absolute Land, the unwillingness, the joy of discovering that Wang Sheng was in the valley, etc., etc., all emotions at this moment were only left with a complex mood, that is, fear and rejoicing.

Fear to the extreme, perhaps there was no feeling. At least everyone didn't feel that they and the people around them were shaking, were shivering. But everyone clearly had a trace of relief in their hearts from escaping death.

Fortunately, they didn't chase in. Fortunately, they were not among those who chased in. Otherwise, they would definitely be like those people inside. The most comfortable thing would be to die on the spot, and the most unfortunate thing would be to suffocate to death later.

So many masters, who hasn't seen dead people? Everyone has personally killed, on average, if not a hundred, then eighty. But when have they ever seen such a terrifying and shocking killing scene? Especially when they almost became one of the piles of corpses, Wang Sheng's figure seemed to have become the most terrifying symbol in the depths of their hearts. Just thinking about it would make them tremble involuntarily.

Those few fifth-level masters had the highest cultivation and the strongest spirit, and recovered the fastest. Awakening from the shock, they immediately realized that something was wrong, and hurriedly shouted loudly several times, waking everyone from the shock.

Fresh air had been replenished, and everyone no longer felt suffocated. As long as they quickly took a few deep breaths and mobilized their spiritual energy to circulate, they could return their bodies to normal.

However, at this time, no one was in the mood to chase anymore. Not to mention crossing the valley to enter the Thousand Absolute Land, just the scene in the valley made everyone lose the courage to chase at this moment.

The Qiu family's fifth-level master who was chasing the fastest was only a little bit away from avoiding the power of the explosion. Unfortunately, it was just a little bit, just a little bit!

His body was thrown high by the power of the explosion and fell heavily. A mouthful of blood sprayed far away. The pain of suffocation almost made him tear his own throat. At this moment, he saw the figure of Wang Sheng, the target he was chasing.

Wang Sheng was still standing straight, wearing a whole set of skydiving equipment, helmet, goggles, rigid nose and mouth protective mask, camouflage uniform, big-headed military boots, Glock 17 in his right hand, and Tiger Tooth in his left hand, and slowly walked to his side.

The Qiu family master couldn't understand why Wang Sheng didn't seem to be suffocating at all, and he didn't understand why Wang Sheng only threw a fire striker, how it caused such terrifying damage. At this moment, his eyes were scattered, his pupils dilated, and he was about to die.

Wang Sheng had become blurred in his eyes. Only one sentence remained in the Qiu family master's mind: "If I had known, I wouldn't have come." Then, he completely fell into darkness.

Through the heavy black smoke, Wang Sheng couldn't see the scene on the opposite side of the valley, but he still shouted loudly at the valley: "Those who are not afraid of death, chase me!"

The valley became the best loudspeaker and repeater at this moment, with waves of sound reflecting and filling the entire valley.

"Those who are not afraid of death, chase me!"

"Those who are not afraid of death, chase me!"

"...chase me!"

"...chase me!"
