Nine Transformations of the True Spirit.

The day after Chen Yuan joined the Thunder Mountain Demon King's forces, he left the Thunder Mountain Range with the Iron Wing Demon General.

The Demon King of Leishan did not bestow any treasures upon Chen Yuan. Firstly, Chen Yuan was merely a guest of the Iron Wing Cave, and secondly, he had only recently joined the service and had not yet made any contributions.

However, Ironwing Demon General had already said that allowing Chen Yuan to establish his own residence was a reward from Thunder Mountain Demon King, and also something Chen Yuan had been seeking.

The two continued to avoid the demon generals and demon commanders along the way, and returned safely to the Iron Wing Cave.

After a short night of recuperation, Chen Yuan went to the Iron Wing Demon General's cave to discuss taking action against the other demon generals.

Chen Yuan asked, "Brother Tie, who do you intend to challenge?"

Ironwing Demon General was clearly prepared, a ruthless glint flashing in his eyes: "Naturally, it's that old thief Minghai. Back then, it was he who took advantage of the situation to invade, causing Ironwing Cave to suffer heavy losses and never recover its strength."

Chen Yuan smiled slightly: "Brother Tie, please feel free to do as you please."

Over the past few months, the two had held numerous banquets, during which he learned a great deal about the Iron-Winged Demon General.

There are three mid-level demon generals who have a grudge against Ironwing Demon General, among whom the deepest grudge is against this old thief from the Underworld Sea.

More than 600 years ago, the Iron-Winged Demon General went on a journey and entered a dangerous place on the Heavenly Skeleton Continent in search of spiritual objects for body tempering.

However, he was unlucky and lost to a mid-level demon general from a royal family while competing for a five-thousand-year-old body-tempering spiritual herb. Although he managed to save his life thanks to his innate escape technique, his injuries were quite severe.

Although the great saints fought privately among themselves, they did not refrain from fighting in dangerous places, as well as in fragments of the interface and secret realms.

Ironwing Demon General, being weaker than others and having nowhere to turn for help, had no choice but to return to his cave to recuperate from his injuries.

However, for some reason, this matter reached the ears of the Demon General of the Underworld, who was six million miles away from the Ironwing Cave. He immediately issued a challenge to the Demon General of the Underworld.

This Nether Sea Demon General is also a mid-level Demon General, with strength comparable to that of the Iron Wing Demon General.

According to the rules of the Burning Demon Realm, as long as he issues a challenge, the Iron-Winged Demon General must accept it.

Only if the Iron-Winged Demon General is currently vying with another Demon General can he refuse.

At that time, he was seriously injured and his strength had not recovered. He forced himself to fight, and naturally he suffered a great defeat.

The burly man had fought alongside the Iron-Winged Demon General and, with good fortune, killed a low-ranking demon general, which led to him being granted the Wilderness Grassland as his territory.

However, the strength of the Underworld Demon General was only similar to that of the Iron Wing Demon General, so he dared not push him to the brink. That battle was not wagered on the entire Iron Wing Cave, nor was it made for the Iron Wing Demon General to cede territory; it was only for some cultivation resources.

Even so, the Ironwing Cave was severely damaged and has not yet recovered. The Ironwing Demon General's cultivation has stagnated, and he deeply resents the Underworld Demon General.

He had mentioned this to Chen Yuan more than once, and now that he had the opportunity to seize the territory of a demon general, he immediately chose the Demon General of the Underworld Sea.

Chen Yuan naturally wouldn't object. He only needed one territory to establish his government; the others, whether rich or poor, vast or small, were insignificant.

The two discussed for a while longer, but it only took an hour to settle everything. Chen Yuan then took his leave and returned to his cave.

Before taking action against the Demon General of the Underworld Sea, the Demon General of the Iron Wings must first issue a challenge; a surprise attack is not permitted, or the violator will be severely punished.

The Great Sages set rules to force the demon race to fight among themselves and forcibly prey on the strong, not to start a war, but to prepare for a great war between the two realms.

However, the great saints should not try to forcibly restrain the unruly demon beasts. Chen Yuan heard from the Iron-Winged Demon Commander that many demon commanders had violated the rules and secretly attacked other demon commanders.

Most of them were captured and executed, but many powerful demon generals remain at large. Some unsolved cases remain unsolved, with no known demon general responsible, or perhaps the demon king or demon saint killed them casually.

Countless demon generals died without cause, including the burly men and the Crimson Blood Demon General killed by Chen Yuan.

Iron Wing Demon General once wanted to seek justice for Crimson Blood Demon General, but he was no match for Chen Yuan. Later, he even tried to befriend Chen Yuan, and the death of Crimson Blood Demon General was no longer of concern to anyone.

Every few years, one of the demon generals under the Iron Wing Demon General would die without cause, either killed by another demon general or simply die for no reason. He would then send out demon generals from his clan to investigate.

Some demon generals didn't care about the lives of their demon generals and dealt with them hastily, leaving those demon generals to die in vain.

However, such demon generals are extremely rare. Their demon generals serve them and pay tribute in ordinary times. They can be used in the war between the two realms and in battles with other demon generals. No demon general would let them die for no reason.

Otherwise, the Demon General would have to spend time and effort collecting cultivation resources on his own, becoming isolated during wartime, adding to the risks, and ultimately losing more than he gained.

The battle between the demon generals is also a battle between the two cave dwellings, and it is divided into a battle of magic between the demon generals and a battle of beast tides.

Demon generals cannot attack demon generals or low-level demon beasts. Last time, when Iron Wing Demon General fought with Nether Sea Demon General, he was defeated because his injuries had not yet healed.

Although the Ironwing Cave Mansion did not suffer a defeat in the battle against the beast tide of the Underworld Cave Mansion, the defeat of the Ironwing Demon General rendered the battle meaningless.

But this time, with Chen Yuan's help, Iron Wing Demon General is no match for Underworld Demon General, so there's no need for further discussion.

The next day, the Iron Wing Demon General sent a demon general to challenge the Underworld Sea Demon General, using the Iron Wing Cave as the stake.

According to the rules, the Underworld Demon General must accept the challenge within three years; otherwise, the Iron Wing Demon General can take action by force after three years.

Of course, Iron Wing Demon General could only issue a challenge while Underworld Sea Demon General remained in his cave.

However, due to his deep-seated resentment towards the Demon General of the Underworld, he knew his whereabouts like the back of his hand and had already discovered that the Demon General of the Underworld had been in seclusion in his cave for the past two hundred years.

After sending out the challenge, the two waited for a reply.

The Iron-Winged Demon General began issuing decrees to summon his demon generals, and Chen Yuan was prepared to wait for three years.

This battle involves two cave dwellings and can be described as a fight to the death. The Demon General of the Underworld Sea will definitely drag it out until the last deadline and make full preparations before replying.

Unexpectedly, three months later, the Demon General of the Underworld sent a reply, along with a letter of surrender.

Chen Yuan was quite surprised that the Demon General of the Underworld surrendered without a fight.

After a moment's thought, Ironwing Demon General sighed, "I have fought that old thief Minghai several times, and the battles have ended in a draw."

"After that last battle, the Iron Wing Cave is far weaker than the Dark Sea Cave. There is no way he would surrender without a fight."

"It can only be that the Demon King secretly reminded me that the old thief of the Underworld Sea already knows that Brother Kun is a guest elder in my cave. He is no match for him, but he does not want to lose his life, so he sent a letter of surrender."

"With the great war between the two realms imminent, the Demon King naturally did not want to see his demon generals suffer losses, so he secretly issued a warning, saving the old thief of the Underworld Sea from death."

Iron Wing Demon General was very unwilling, as he failed to take the opportunity to eliminate Underworld Demon General.

Chen Yuan was quite pleased. With the Nether Sea Demon General presenting a letter of surrender, there was no need to fight this battle anymore, saving him a lot of trouble and more than two years.

The Iron-Winged Demon General immediately issued a second decree, ordering the gathered demon generals to return on their own, while he himself would lead his clan's demon generals to join Chen Yuan in taking over the Nether Sea Cave. (End of Chapter)
