I only reached the Foundation Establishment stage at eighty years old, and then the system appeared.

The demons are preparing to join forces to attack a top-tier sect, the Cangmang Immortal Sect, located in the northern region. The sect has over 20 million members, four Immortal Emperors, and three warships.

The Cangmang Immortal Sect is hundreds of billions of miles away from the Jingjue Sea coast. The Demon Clan's plan was to use all the confinement arrays to cut off the Cangmang Immortal Sect's escape and communication routes. Then, the thirty-five Demon Emperors and thousands of Demon Kings would act together, breaking through the Cangmang Immortal Sect's protective barrier at an extremely fast speed and attacking the sect.

A top-tier sect has at least tens or hundreds of thousands of Immortal Kings and one or two hundred Immortal Emperors. If this operation succeeds, it will be enough to give these Demon Emperors a 300 to 400% success rate in completing their mission.

Once the mission is complete, they will impersonate members of the Cangmang Immortal Sect and send a distress message to the Allied Forces headquarters. When everyone's attention is focused on the Cangmang Immortal Sect, the demons will quickly evacuate along the planned route.

Unfortunately, these were all just wishful thinking on the part of the demons. Fantasies are just fantasies. What these demons didn't know was that the Yang family had a warship searching for the demons' whereabouts in the void and discovered the traces of this group of demons secretly gathering.

When Yang Hongbo received the message, he initially wanted the Yang family to devour the demon army themselves. However, after thinking about it, he decided to send a message to the Grand Elder of the Allied Forces Headquarters, since he still had several subordinates serving as stewards there!

"Elder, a Celestial Emperor from the Yang family outside requests to see you!"

"Oh, then please come in quickly!"

Soon, the Immortal Emperor of the Yang family was brought into the council of elders.

"Greetings, Elder!"

"Hello, hello, may I ask what brings you here, Emperor Yang?"

"Elder, our Yang family has discovered the whereabouts of seven demon armies. We would like to ask if the Great Hua Imperial Sect should join this war to exterminate the demons!"

"Although our Yang family can complete this annihilation campaign independently, we can only eliminate most of the high-level demons, and only allow a few low-level demons to escape."

"Oh dear, if we can wipe out this group of demons in one fell swoop, our Great Hua Imperial Sect will certainly do our duty without hesitation and achieve a complete victory. This would definitely be the most eye-catching battle in the history of the Immortal-Demon War."

"Haha, I'll report this to the sect immediately. The sect leader will be very happy!"

Soon, the sect leader of the Great Hua Emperor Sect received a message from the sect's Grand Elder (the sect's seventeenth elder) who was serving at the Allied Forces Headquarters.

"What? The Yang family has already discovered the whereabouts of the remaining seven demon armies? And they're planning to join forces with us to wipe them out!"

"Excellent! I originally thought that being able to wipe out most of the Demon Emperors would be an incredible stroke of luck. If we can truly end this once-in-a-millennium chaos in one fell swoop, we will surely be recorded in history and enjoy the eternal worship of the Immortal Continent!"

After all, previous invasions by the Demonic Clan lasted for nearly five hundred years. If this one ended in just one hundred years, and the enemy was almost completely annihilated, the Demonic Clan would have to think twice about the consequences if they wanted to invade again.

"This time, all ten of our sect's warships have been deployed. Could you please tell the Yang family where we should meet?"

"What? The Yang family made our warships remain hidden in the void the entire time to avoid being discovered by the demons, and they even covered all the top-grade immortal crystals consumed by our warships?"

"We're meeting at Flying Eagle Ridge in the Fairy Phoenix Forest, right? Okay, we'll be there soon!"

The communication ended, and the massive army of the Great Hua Emperor Sect immediately boarded ten warships, which then vanished into the void and sped toward their designated targets.

In the void above the Flying Hawk Ridge in the Immortal Phoenix Forest, fourteen warships had been waiting quietly for a long time. When ten warships of the Great Hua Emperor Sect arrived, Yang Hongbo immediately flew to the flagship of the Great Hua Emperor Sect Master.

"Sect Leader Shi Feihua, thank you very much for the assistance of your Great Hua Imperial Sect!"

"Haha, Clan Chief Yang, we are all related by blood. This time, our joint attack on the enemy will surely achieve unparalleled feats!"

The sect leader looked at the fourteen flying ships of the Yang family before him, and thought, "The Yang family is amazing! They've deployed fourteen flying ships just for this battle! It seems the Yang family's main clan in the God Realm is quite formidable!"

[The Yang family was able to deploy fourteen airships this time, and they must have at least a few more in their own family, plus the ten they sold to my sect, damn! Doesn't that mean the Yang family received the thirty warships bestowed upon them by the Upper Realm?]

"Clan Chief Yang, what are your plans for this battle?"

"It's very simple. Each of our two families will send seven airships to deal with the seven flagships of the demon race, and the remaining ten airships will surround the remaining demon army."

"The demon army is now over 100,000 miles ahead. Let's just proceed with the plan and take them down!"

As all the airships flew above the demon army, the demon cubs below were still making a ruckus and preparing. They were all very excited. The thought of launching a strong attack on a top sect made all the demon cubs eager to fight, their eyes gleaming with bloodlust.

However, they were unaware that the shadow of death had already quietly loomed over them.

"Begin the operation!" With a command from Yang Hongbo, the fourteen warships of the Yang family and the ten warships of the Great Hua Emperor Sect, a total of twenty-four warships, were like twenty-four sharp swords, pointing straight at the heart of the demon army!

The warships of the Yang family and the Great Hua Emperor Sect had locked onto the Demon Clan's flagship. Two warships against one, and the seven Demon Clan flagships were instantly destroyed under the powerful firepower. The Demon Emperor on the flagship was unable to exert any effect and was already turned to ashes.

"No! This is impossible!" A demon emperor watched as his demon race's flagship was destroyed, his eyes filled with resentment and despair.

"Haha, you little devils, your doomsday has come!" Yang Hongbo stood on the command platform of the spaceship and laughed loudly. His voice resounded throughout all the warships through the spaceship's loudspeakers.

With the destruction of seven demon flagships, the remaining demon army descended into chaos. They couldn't even see the warships and could only passively endure attacks from all sides. Anyone attempting to escape was instantly killed by the warships, without even a chance to resist.

"Clan Chief Yang, these flying ships are truly amazing! They can even attack by disappearing into the void, leaving the demons with no trace of them!" Sect Master Shi Feihua exclaimed as he looked at the battle before him.

"Haha, Master, you flatter me. Only such advanced warships can give us a huge advantage in battle," Yang Hongbo said modestly, but his face was filled with a proud smile.

As time went on, the demon army suffered increasingly heavy casualties. They attempted to organize an effective counterattack, but against the overwhelming firepower of the warships, their counterattacks proved utterly futile.

At this moment, the warships materialized from the void, and the immortals aboard descended to join the attack. One immortal king, while attacking, taunted, "You demon bastards, didn't you want to devour our flesh and blood? Come on, don't be cowards!"

"Hmph! Don't be too smug! We demons will not admit defeat easily!" a demon emperor roared, trying to ignite the fighting spirit of the demon army.

However, his roar had no effect. The demon army was already in despair; they knew that this time they were truly doomed.

On the chaotic battlefield, the scene was filled with immortals chasing demons. Some demons with more courage mustered their courage and started to self-destruct, with mushroom clouds blooming on this bloody battlefield from time to time.

"Clan Chief Yang, do you think we should close the net now?" Sect Master Shi Feihua asked Yang Hongbo, looking at the demon army that had basically lost its fighting power.

"Okay, that's fine. Have all the airships cease attacking, then we'll go down and clean up the mess," Yang Hongbo nodded and said.

With the order relayed, all the warships ceased their attack. Then, the high-ranking immortals from the Yang family and the Great Hua Imperial Sect flew down from their ships and began cleaning up the battlefield.

"Haha, we've really won a great victory this time!" A Celestial King from the Yang family laughed as he looked at the corpses of demons scattered all over the ground.

"Yes, this time we not only annihilated seven armies of the demon race, but also killed more than thirty demon emperors. It was an unprecedented victory!" Another immortal emperor from the Great Hua Emperor Sect echoed.

"This victory is all thanks to the Yang family's warships and Sect Master Shi's wise decisions!" The elders of the Great Hua Imperial Sect said excitedly as they looked at Yang Hongbo and Sect Master Shi Feihua.

"You flatter me. This is the result of our joint efforts. If it were just us alone, I'm afraid we would not have been able to achieve such a victory," Yang Hongbo said modestly.

"Haha, no matter what, we've accomplished a great feat this time! When we get back to the sect, we'll definitely have a big celebration!" Shi Feihua said with a hearty laugh, his mood incredibly joyful.

With the battlefield cleared, the immortals of the Yang family and the Great Hua Imperial Sect began returning to their spaceships. They knew that although they had achieved victory this time, the road ahead was still long. The Demon Clan would not easily give up its invasion of the Immortal Clan; they must remain vigilant at all times and be ready to meet new challenges at any moment.

This victory further strengthened their resolve. They believed that as long as the two sides joined forces, they could achieve final victory no matter what kind of enemy they faced.

On their way back to the Great Hua Emperor Sect, Yang Hongbo and Sect Master Shi Feihua stood at the bow of the flagship, gazing at the distant sky. Their hearts were filled with anticipation and longing, anticipating more victories and glory in the future, and yearning for peace and prosperity on the Immortal Continent.

"Sect Master, how much impact do you think our victory will have on the Demon Clan once the news gets out?" Yang Hongbo suddenly asked.

"Hehe, the impact will definitely be huge. This time, we not only eliminated a large number of high-level demons, but also demonstrated our formidable strength. I think the demons will not dare to launch an attack on us easily for a while," Sect Master Shi Feihua said with a smile.

"Yes, that's what I think too. However, we can't let our guard down. The demons are cunning and resourceful; they might come up with new ways to deal with us. We must remain vigilant and be prepared to respond at all times," Yang Hongbo nodded and said seriously.

"Clan Chief Yang is right. We certainly cannot let our guard down. However, I believe that as long as our two families join forces, no matter what methods the demons come up with, we will be able to deal with them with ease," Sect Master Shi Feihua said confidently.

The two exchanged a smile, then continued gazing at the distant sky. Their hearts were filled with confidence and determination, ready to face even greater challenges and victories in the future.
