From the Abyss Invasion to the Blasting Star.

Chapter 344: The Legend of the Fire Demon Gross
Legend has it that the Fire Demon Gross was originally the ruler of the Lava Crown on the Dragon Sleeping Continent.

Later, a tribe of Dark Iron Dwarves named Copperfurnace migrated to Lava Crown to escape the Abyss. They discovered rich geothermal resources underground and decided to settle down in Lava Crown.

From that day on, the Copperforge Black Iron Tribe and the Firelord Gross of the Lava Crown began a ten-year battle.

The battle between the Copperforge Dark Iron Tribe and the Firelord Gross lasted too long, and there were many times when the Copperforge Tribe wanted to give up and find another habitat.

Until the Dark Iron Dwarf King named Thorendar Copperforge appeared and led the Dark Iron Dwarves to defeat the Firelord Gross and win the victory.

After the death of the Firelord Gross, his ashes were scattered under the Lava Crown, looking for a chance to be resurrected.

Before his death, Thorendal Copperforge was worried that the Firelord Gross would make a comeback and destroy the kingdom that the Copperforge tribe had built half of the world, so he used his last bit of strength to seal the ashes of the Firelord Gross underground.

This is the legend about the Balrog and the Dark Iron Dwarf Kingdom.

Lu Heng had heard of this legend, but it was a legend that was not spread until two years after the abyss descended.

Unexpectedly, Gross Embers appeared now.

The volcanic ash transported by this shipwreck contains the embers of Gross, so after being ignited it will burn and form a conscious flame.

After figuring this out, Lu Heng finally understood why the Dark Iron Dwarves wanted to transport the volcanic ash to the tidal sea and dump it.

The Dark Iron Dwarves probably wanted to pour the ashes of the Firelord Groth into the depths of the sea, thinking that this would prevent the Firelord Groth from reviving.

……

Lu Heng immediately returned to the Siren Temple to find the High Priestess Sona, and said as soon as they met: "I know what volcanic ash is. Take me to the place where the Dark Iron Dwarves dumped the volcanic ash."

High Priest Sona frowned and thought, looking at Lu Heng with her sharp eyes, and nodded in agreement after a moment: "Okay. I'll take you there, I hope you really have a way to resolve this crisis."

This time, Sona did not send guards to take Lu Heng to the destination, but led the team herself.

Lu Heng and his group of ten people followed the Sirens team, crossed the deep frozen trench, and came to the deepest waters of the Tidal Sea.

High Priest Sona floated in the sea water, raised her hand and pointed downwards and said, "It's right below. This is the deepest part of the Deep Frozen Trench. You may not be able to go down."

As she spoke, she raised her hand and released a bubble that enveloped Lu Heng and the others, then swam down first.

The deeper you go, the deeper the sea water becomes. After diving six kilometers, the temperature drops from twenty degrees to just over ten degrees.

When approaching the seabed, Lu Heng finally vaguely saw the situation on the seabed.

There is a sunken area on the seabed, and at this moment, there is a lot of black mud piled up in this area, which is clearly volcanic ash that has been soaked.

Not all volcanic ash is Gross embers, but the volcanic ash contains Gross embers.

The Dark Iron Dwarves probably had no way of extracting the Gross Embers from the volcanic ash, so they simply transported the excavated volcanic ash here and dumped it.

Lu Heng was covered with bubbles, so he could speak: “Why did the Dark Iron Dwarves dump the volcanic ash here?”

High Priest Sona pondered for a moment and asked, "Didn't you say you knew what volcanic ash was?"

"If I'm not mistaken, the volcanic ash contains Gross ashes." Lu Heng expressed his guess.

High Priest Sona nodded and confirmed, "It seems that you do know part of the truth. Then I will tell you the rest.

“This is called the Deep Frozen Trench, and it’s the coldest place in the Tidal Ocean.

"Ten years ago, the seabed here was covered with ice all year round, and the sea temperature could reach minus three or four degrees Celsius.

"But, do you see any ice here now?"

After listening to it, Lu Heng understood what it meant.

The Dark Iron Dwarves dumped the embers of Gros here, which actually raised the temperature of the nearby sea area by more than ten degrees.

Gross embers can actually raise the temperature of sea water. What would happen if they were not poured into the deep sea?
I'm afraid that the Fire Demon Gros has already revived. Even if not all of him has revived, at least some of his ashes will have revived.

No wonder the Dark Iron Dwarves were willing to make enemies with the Sirens and dump volcanic ash into the sea. They made this choice for survival.

The ashes of the Firelord Gross have been buried beneath the Dark Iron Dwarf Kingdom for a century. Once it awakens, one can imagine what will happen to the Dark Iron Dwarf Kingdom.

With no way to deal with the Firelord Gross, the Dark Iron Dwarves could only choose to dig out Gross's ashes and find a cold place to dump them.

So they chose the coldest spot in the Tidal Sea.

What the Dark Iron Dwarves didn't expect was that dumping the Gross Embers into the Deep Frozen Trench would actually increase the temperature of the sea water here.

Lu Heng thought about this and asked, "So the sea water temperature in the Siren's territory has also risen, right?"

High Priest Sona sighed, exhaled a bubble from her mouth, nodded and replied: "Yes, the sea water temperature in our sea area has risen by two degrees in ten years. Do you understand how huge this change is for us?"

Of course Lu Heng understood.

To make an analogy, the environmental changes faced by the Sirens are similar to the greenhouse effect on the Blue Planet.

Humans are also trying various ways to control global climate change caused by the greenhouse effect.

The situation of the Sirens is even more serious, as changes in sea temperature have a more profound impact than changes in atmospheric temperature.

No wonder the Sirens attacked the Dark Iron Dwarf ships; any other race would have done the same.

……

Afterwards, High Priest Sona revealed the sequel to the legend of the Firelord Gros.

It turned out that after the Copperforge Dark Iron Dwarf Kingdom had thrived in the Lava Crown for more than a century, the ashes of the Firelord Gross buried underground showed signs of revival.

With the death of the Dwarf King Thorendar, there is no one in the Copperforge Tribe who can deal with the Firelord Gross.

The great wizard of the Copper Furnace tribe discovered this and after discussing with the seven elders of the tribe, they finally decided to dig out the ashes of Gross and transport them to the coldest place for burial.

Finally, the Dark Iron Dwarves chose the coldest place in the depths of the Tidal Sea, the Deep Frozen Trench.

The great wizard of the Copper Furnace Black Iron Tribe dived to the bottom of the sea to check it out, and saw underwater glaciers stretching for hundreds of miles. This is a very peculiar kind of ice, containing special qualities. It is embedded in the seabed, forming an underwater world like ice crystals.

The great wizard of the Dark Iron Dwarves felt that dumping the ashes of the Firelord Gros here would surely prevent his resurgence.

So, starting ten years ago, the Dark Iron Dwarves have been continuously transporting volcanic ash by ship and dumping it into the deep frozen trench.

At the beginning, it didn't cause much change.

As the situation continued, the glaciers in the deep frozen trench began to melt and the temperature continued to rise, indirectly affecting the sea water temperature in the Siren's territory.

Three years ago, the Sirens discovered the purpose of the Dark Iron Dwarves dumping volcanic ash, and the contradictions between the two tribes continued to escalate and conflicts continued.

The Sirens prohibited any Dark Iron Dwarf ships from entering the Tidal Sea. However, the Tidal Sea was too large for the Sirens to block all sea areas, so the Dark Iron Dwarfs continued to dump volcanic ash into the deep sea.

Even many Dark Iron Dwarves only know to dump volcanic ash into the tidal sea, and don't know why they do so.

This has been a task that has been going on for ten years, and many Dark Iron Dwarf captains, including Friggs, are just following orders.

As for why they do this job, it is not a question they need to worry about.

……

After listening to the whole story, Lu Heng finally understood why the danger level of the abyss battlefield was level 7.

There is a powerful demon king in this world, the Fire Demon Gross.

Simply dumping Gross Embers into the deep ocean can raise the temperature of the tidal sea.

You can imagine how terrifying this fire demon Gross is.

It is also because of the existence of Gross Embers that irreconcilable conflicts arise between the Sirens and the Dark Iron Dwarves.

In a sense, the conflict between the two ethnic groups is indeed irreconcilable.

The ashes of the Firelord Gross are buried underground in the Dark Iron Dwarf Kingdom. If the Dark Iron Dwarves do not dig out the ashes of Gross and dump them into the deep sea, when the Firelord Gross is revived, the Dark Iron Dwarf Kingdom will be doomed to be destroyed.

If the Dark Iron Dwarves want to prevent the revival of the Firelord Gross, they must continue to dump volcanic ash into the sea.

The ashes of Gross poured into the Tidal Sea. Not to mention whether the Fire Demon Gross will revive on the seabed, even if he does not revive, the increase in sea temperature alone will have a huge impact on the Sirens.

Conflict is inevitable between the two races in their quest to protect the climate environment of their habitat.

There is no solution to the conflict between the two races unless the threat of the Fire Demon Gross can be resolved.

But is it possible to solve a problem with a powerful demon king whose ashes alone can raise the temperature of the sea?

This matter seemed to have no solution from the beginning.

Lu Heng recalled carefully, searching his memory for all the information related to the Fire Demon Gross.

There is indeed a lot of information about the Fire Demon Gros in my memory, but until my rebirth, I had never heard that the issue of the Fire Demon Gros had been resolved.

In fact.

The information about the Fire Demon Gross in the memory should have appeared two years after the advent of the abyss.

In other words, this incident should not be brought to light until half a year later.

If you think about it for a moment you'll know what's going on.

This is the first time that humans have been recruited into the Siren World, and the first recruitment in the previous life was around this time.

At this point in time, there were very few marine-type psychics among humans, and their combat capabilities were generally not high.

The first batch of marine-type mutants recruited here could not provide much help in this world. Not to mention completing world missions, they did not even have the ability to complete challenging missions.

In other words, the first batch of psychics recruited in the previous life most likely returned after completing the main mission.

They had not investigated the cause of the deterioration of the Tidal Sea environment, so naturally they did not know that the volcanic ash dumped into the Tidal Sea by the Dark Iron Dwarves was the remains of Gross.

After the first conscription, humans began to pay attention to the training of marine psychics.

The combat power of the marine psychics recruited subsequently increased gradually. When it was enhanced to the point where it could influence the world's pattern, the secret of Gross's Embers was finally discovered.

In other words, in the previous life, humans learned the secret of Gross Ashes half a year later, but in this life, because of Lu Heng's participation, this time was greatly advanced, and the secret of Gross Ashes was discovered during the first conscription.

However, simply finding out the secret of Gross's Embers will not change the world's situation.

The problem still exists.

The conflict between the Sirens and the Dark Iron Dwarves remains unresolved.

As for getting rid of the fire demon Gross.

Lu Heng has no idea now.

The information about the Fire Demon Gross in the memory was not resolved until three years after the advent of the abyss.

It has only been a year and a half since the abyss descended. Is there any way to get rid of the fire demon Gross at this time?
This is simply an impossible task.

After thinking carefully, Lu Heng looked up at the high priest Sona and said, "High priest, you should know better than me how powerful the Fire Demon Gross is.

“So I’m afraid this crisis cannot be solved by a single call-up.

“If this recruitment fails to resolve the crisis, when I return, I will publish information about this world and call on the humans who are recruited next time to continue helping the Sirens resolve the crisis.

"I only hope that the Sirens and the Dark Iron Dwarves can temporarily put aside their prejudices and work together to think about ways to resolve the crisis."

After hearing this, High Priest Sona fell silent.

She did not agree to Lu Heng's request, but she did not object immediately either.

Lu Heng knew that as the high priestess of the Sirens, she could not make a major promise just because of a few words from a recruiter.

So I continued to lobby, “I understand that the high priest may not believe me, but that’s okay. As long as the high priest does not object to what I say, and we continue to work towards the same goal, we will find a solution to the problem one day.”

High Priestess Sona was of course aware that even with the combined forces of the Sirens and the Dark Iron Dwarves, a terrifying fire lord like Gross could not be destroyed, so it was impossible to place all hope on the Summoner.

The question she was actually considering was whether to reconcile with the Dark Iron Dwarves?
In fact.

Being hostile to the Dark Iron Dwarves will not benefit the Sirens in any way.

The Sirens cannot obtain any resource compensation from the Dark Iron Dwarves, so it is meaningless to attack the Dark Iron Dwarves.

There was only one reason why they attacked the Dark Iron Dwarf ships, and that was to stop the Dark Iron Dwarves from dumping volcanic ash into the Tidal Sea.

High Priest Sona pondered for a moment and said, "I may not be enemies with the Dark Iron Dwarves, but the Dark Iron Dwarves may not think so."

Lu Heng knew that in order to resolve this matter, he had to talk to the current Dwarf King of the Dark Iron Dwarf Kingdom. After thinking for a moment, he said:

"I will set off for the Dark Iron Dwarf Kingdom to talk to their king, hoping to mediate the relationship between your two tribes. The high priest can tell me what he wants."

High Priestess Sona pondered for a moment and made only one request: "My request is very simple, there is only one thing, that is, the Dark Iron Dwarves cannot continue to dump volcanic ash into the Tidal Sea. As long as the Dark Iron Dwarves agree, we will immediately cease fire."
