The host is a slime [Quick Transmigration]

They would come to the conclusion that it wasn't that Ohm had God's perspective or that there was a system plug-in called Lady, but that the death symptoms of the lions and vultures were almost the same as those of hydrogen sulfide poisoning.

If hydrogen sulfide is smelled for a long time or the concentration is too high, it will paralyze the nerves, resulting in the symptoms of suffocation and death.

Judging from the performance of the lions and vultures, they most likely inhaled a high concentration of hydrogen sulfide gas instantly!

The instigator was not the "monster" Amanda thought before, but the gas hydrogen sulfide.

At first glance, it seemed unbelievable that a kind of gas destroyed a piece of paradise, but Ohm, who had already seen some chemical attacks, quickly understood.

Because hydrogen sulfide is fatal to animals and insects.

Only this kind of gas will directly destroy the vitality of the maggots when they are still eggs, and those flies that lay eggs will be killed one step ahead of time, so naturally they can only appear in the state of "air-dried" death.

Then the corpses of lions or other predators and herbivores were also found in more than a dozen other places in the Red Valley, which also proved this point-they passed the vast sand dunes on the way, and saw many sand snakes, sand scorpions, lizards, Gerbils lie motionless on the surface of the desert or half-buried in the sand. Because of the large temperature difference and lack of water in the desert, the corpses of those animals are basically skinny and boneless.

Over the dunes, they also passed a salt marsh formed by a lake that dried up thousands of years ago. This salt marsh is a cracked land in the dry season, but after the rainy season, enough rainwater makes the dense weeds germinate, and there will be zebras, Many wild animals, including wildebeests and flamingos, came here and showed great vitality—but when Ohm saw it, although there were still dense weeds, all the pink flamingos fell to the ground , Their original dazzling feathers have also become dull after being exposed to the wind and sun. Some flamingos fell into the lake and were mashed by the water. Together with the fish floating on the water with their white bellies, they looked like Poor and horrible.

After the flamingos, they encountered the territory of the rhinoceros with thick and hard skin. As tough-tempered and tough bones, even the lions seldom hunted them. At this time, they lay quietly in the mud , as if not dead, but just asleep.

All of them, without exception, were all frozen in a certain moment, and their lives were quietly and quickly taken away.

※※※

And with Ohm and Atum walking through the major geographical locations of the Red Valley, Lady has used the collected data to draw most of the territory into a map, and at the same time deduced the disaster that happened in the Red Valley at that time.

Under the lake that Ohm and Atum saw at the beginning, there has actually been a dormant volcano at the bottom of the lake.

The so-called dormant volcano is a volcano that has erupted in the past, but has been in a relatively static state for a long time.

This is the case with the volcano under the lake. Many years ago, when it was still on land, this volcano erupted. Later, because of the low terrain, water accumulated after repeated rainfalls. After time transfer, a lake was formed. The volcano was submerged in water.However, because the volcano still retains a complete volcanic cone shape, it still has volcanic activity-although there is no eruption activity, high-temperature gas is continuously ejected from some unfathomable fumaroles on the hillside, and in a certain period The substance hydrogen sulfide will be released, which will form gas through the water source, and will emit an imperceptible "rotten egg" smell. Over time, hydrogen sulfide will paralyze people's nerves, causing suffocation symptoms and causing death.

It's just that because the lake is relatively deep, the water pressure in the bottom area of ​​the lake is naturally high. The carbon dioxide does not float to the surface in the form of bubbles, but dissolves into the lake water.

In this way, more and more hydrogen sulfide gas accumulated in the lake for hundreds of years.

All this happened in the water of the lake, and very little escaped the water, so it was not obvious from the outside.Even because of the evolutionary characteristics of the survival of the fittest, the aquatic organisms that can survive in the shallow water layer of the lake have their own resistance to hydrogen sulfide.

It's just that hydrogen sulfide is too destructive to the body's functions, resulting in the absence of slightly larger and more complex organisms in the lake—but from another perspective, it makes the lake water extremely clear.

Even the longest-lived elephants are only 80 to [-] years old. Although the past history and experience can be passed on orally, there are too many missing parts.

For a long time, the Red Valley has been quiet and peaceful, so when the Saivan Lions and other races lived in the Red Valley, they had no idea that there would be a time bomb where they lived day and night.

On the last day of this rainy season, the thunder and lightning, the roaring thunder and the bright and blinding lightning made the animals who are naturally afraid of this can't wait to find a place they think is safe to hide.

It's just that when they were avoiding the threat from the sky, they didn't expect that the real crisis would come from the ground.

The cause of the disaster was not the eruption of a dormant volcano at the bottom of the lake, but a landslide on the shore of the lake.

Excessive rain in the rainy season is easy to cause landslides, but on the night when the rainy season ended, lightning struck the ground many times.

At that time, Ohm and Atum were fighting with the Glen lions. Ohm used the electric sparks shot down by lightning to kill the lion Gerry together with the cheetah brothers-if the biggest disaster for Ohm and them at that time was not the lightning. If the fire from the sky caused a big fire, then for the animals in the Red Valley, the lightning that hit the ground would be a catastrophe.

Because a large amount of hydrogen sulfide gas released by the magma of the dormant volcano in the early stage entered the lake water from many cracks at the bottom of the lake, and accumulated over time, the entire lake was a crater, and the inner wall of the volcano collapsed after weathering.

The wood and stones struck down by lightning caused huge earthworks to fall into the lake, breaking the pressure balance at the bottom of the lake. The hydrogen sulfide gas accumulated at the bottom of the lake was released from the water instantly, mixed with lake water, and spewed out from the lake like a fountain. .

It's like a sealed beverage filled with carbon dioxide. Before the lid is opened, no matter how many bubbles there are, it is stable and safe. But once there is an external force to shake and open the bottle cap at the same time, the gas inside will spurt with liquid. out!

Hydrogen sulfide gas can be more deadly than carbon dioxide gas.

The water mist mixed with hydrogen sulfide quickly drifted around with the wind in the storm, and quickly spread around the lake surface... The final result was that, from lions to ants, nothing survived.

※※※

The only good news is that hydrogen sulfide gas is not permanent, and this poisonous gas will slowly dissipate over time, but in this nature, the speed will be slower.

This also means that, at least for a short period of time, the area of ​​Red Valley is really not suitable for the animals that migrated back to live and live.

It took Ohm, Atum, and Lilian about five days to leave the Red Valley, and the concentration of hydrogen sulfide in the air became thinner and thinner as Ohm and Atum moved forward. The dead bodies still made them shudder, even if the lady told Ohm that there was no hydrogen sulfide in the air at this time, it didn't ease Ohm's heavy heart.

However, the situation did not allow Ohm to be too immersed in a heavy heart, and the entire caracal was attracted by the tremor of the ground.

Ohm looked up, and there was a piece of rolling loess in front of him, as if the whole land was shaking.

Because he had only communicated with lady about the situation in Red Valley, Ohm subconsciously thought it was an earthquake or something, but a sound of elephant chirping immediately gave the answer: "Moo——!!"

The leader is a huge and menacing female elephant. Her wide ears, thick horns and long and curved ivory endow her with unstoppable aura.

"Brother Ohm, run away!" Although Atum had been thinking about eating elephant meat for the past few days, it was only for juvenile elephants. Facing such a huge animal × N, even though he was a white elephant with a huge body and superb hunting skills The lion can only avoid its edge.

But Ohm, who has a keen sense of hearing, feels that the other party Xiang Moo seems somewhat familiar.

Before he could find the answer from his memory, Lilian, the little elephant who was munching and thorning the cactus behind them, let out a surprise "moo!" rushed over.

The elephant herd came aggressively, originally for revenge, so their attention was on Ohm and Atum, but when they saw Lilian's petite body (Ohm: Are you kidding me?) When they were in sight, the leading female elephant suddenly slowed down, raised her trunk and let out a cry, and the following elephant herd slowed down their pace.

Lilian recognized that this was her family's elephant herd. She ran over ecstatically, but was blocked by the leading female elephant with her trunk.

Lilian didn't know it was because she had been with Atum and Ohm for the past few days, and her body smelled like a lion and a caracal, which made the female elephant hold on to this creature that looked like a baby elephant but smelled like a beast. Examine the attitude - as the leader, any threat that may cause danger to the group cannot be let go - seeing that I finally met my family and relatives, but was rejected by them, the whole elephant was not well, crying and turning around circle, and tried to come forward over and over again.

At the critical moment, it was Lilian's mother, Shakira, who recognized her child. She walked out from behind the leader, hooked tentatively with Lilian's nose with her long nose, and smelled the scent of the other's buttocks. It was finally confirmed that this little elephant with the breath of a beast is the daughter who thought he had been killed!

Shakira was overjoyed, and mooed a few times towards the tribe, and the elephant herd also reacted, and surrounded the lost and recovered baby elephant one after another...

"I said, if you don't run now, when will you wait?" A familiar voice suddenly sounded not far away, causing Ohm to turn his head suddenly. Isn't Trafah hiding behind that bread tree!

They're here too?

The reunion of friends was naturally extremely joyful, but just as Ohm walked a few steps, dozens of elephants over there surrounded him with heavy steps.

Seeing this, Trafal stopped hiding, jumped out from his hiding place, and ran to Ohm with his long legs, looking like he was fighting against the enemy, followed by three figures.

Three ways?

Not just Nelson?

As soon as this question was formed in his mind, Ohm only had time to take a quick glance, it seemed that there were also two leopards, and then his attention was drawn by the elephants - after all, when an adult elephant stood in front of him, it was too prominent Its presence is simply impossible to ignore.

Atum and Trafal subconsciously took a defensive posture, but Ohm shook his head at them.

The leader of the female elephant is really too big. In comparison, the petite caracal looks even smaller. It seems that she has never talked to such a small creature or a predator. The voice of the female elephant has been lowered a lot. Even so, it rumbled in Ohm's ears.

Facts have proved that Ohm's idea is correct. Not only the hatred and anger of the elephants dissipated, but because of Lilian's coquettish words, they learned that white lions and caracals are taking care of the baby elephants these days.

Hydrogen sulfide gas is extremely harmful to animals, but it has little effect on plants. Otherwise, Ohm and Atum would have a headache for Lilian's feeding problem—it can't be helped, although Lilian is still a baby now, she The daily food intake is also surprisingly large.Fortunately, Lilian knows that there is no breast milk to drink now, so tender grass and leaves are always welcome.

It's just that Lilian lost a little weight during the period of breastfeeding, but she was in good spirits and alive and kicking, which made Shakira very happy.

As a group of elephants with a strong sense of group and the cubs are the treasure of the whole group, they are completely grateful to Ohm and Atum at this moment.

For the gratitude of the elephant herd, Atum and Trafa were completely dumbfounded. They thought that a big battle was going to break out, but they didn't expect that not only the thunder was loud but the rain was small, and the rain hadn't even hit their own hands. The body has turned into blossoming flowers?

But looking at the wise and profound kind eyes of the female elephant leader, at least a few of them can no longer think about eating baby elephants... emmm, at least the group of elephants in front of them can be crossed out from the recipe.
