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

While the Yang family's immortal legion was swatting rats in the underground cavern, Yang Hongbo was having Xiao Huizhou play with crystal energy cannons on the spaceship. These crystal energy cannons had adjustable attack intensity; the strongest could kill a Demon Emperor with a single shot, while the weakest could still kill an Immortal King.

Yang Hongbo turned the power of the crystal energy cannon to the lowest level and let his great-grandson attack the small hills. Even an attack from a Celestial King could destroy a small hill in one hit. Xiao Huizhou had a lot of fun.

Some of the family legions below have already returned after completing their missions, but a large number of teams have not yet completed the task of killing the demons.

Because some of these underground caves were indeed too deep—one of them was over 10,000 miles long and had many branches—the pursuing team had to call for backup.

More than 100,000 immortals entered one cave, while only a few hundred demons escaped into the cave, including more than ten Immortal Kings. The deeper they went, the more they deliberately created illusions. At each fork in the road, they would send two or three demons through that fork and try their best to stir things up inside, making it seem as if a large force had passed through.

Based on the feedback from the immortals obtained through the lottery, Yang Hongbo on the spaceship knew exactly where the cave led, so he steered the spaceship there.

There was a small hole here, easily missed if you weren't paying attention. Yang Hongbo aimed a crystal energy cannon at the hole: "Little Huizhou, when the ancestor tells you to fire, fire! The bad guys will come out soon!"

"Really? That's great!"

Soon, a demon cub emerged from the cave. He was just a low-level Earth Immortal, and he couldn't see the warships hidden in the void. Seeing that no one was outside, he went back into the cave.

Soon, a group of demons emerged from the cave. Before they could scatter, Yang Hongbo shouted, "Fire!..."

Yang Huizhou immediately activated the crystal energy cannon, which was now adjusted to the Immortal Emperor level. With one shot, the group of demon bastards were instantly reduced to ashes in a dazzling burst of light.

"Yay, Ancestor, I hit it! That was so much fun!"

The operation to annihilate the demon army lasted for three days and three nights, until the last little mouse was chopped into ashes before the Yang family's army returned to the ground.

Yang Hongbo also brought Xiao Huizhou back to the family. That day, he released the Heavenly Wolf from the Lesser Thousand Worlds to play with Xiao Huizhou. The Heavenly Wolf was also very curious when it heard that Xiao Huizhou could not cultivate human techniques, so it investigated it itself.

"Master, more than 70% of Xiao Huizhou's blood essence comes from the fox clan."

"How is that possible? Our Yang family has never had a fox clan ancestor!"

"I think it's probably related to his mother!"

So Yang Hongbo immediately asked Yang Tujin to bring his grandson and his wife over.

Yang Tujin's grandson is named Yang Jiuye, and his granddaughter-in-law is named Liu Xiaoli. The couple knelt down and kowtowed when they saw Yang Hongbo, saying, "Greetings, Great-Grandfather!"

"Alright, alright, get up!"

The two stood up!

Both of them are now at the Celestial Immortal Realm. Looking at them, Yang Hongbo asked, "Xiaoli, did your family have a fox clan ancestor in your family?"

"Ah, great-grandfather, how did you know? My third-generation ancestor once married a fox clan woman, but she disappeared after giving birth to a son."

"Do you know the concentration of fox clan blood essence in your body?"

"I know that I am also a direct descendant of that fox clan ancestor. I only have three percent fox clan blood essence."

"Then your son must have reverted to his ancestral form; he has 70% fox clan blood in him."

"Huh? Is it that outrageous?"

"Now I'm telling you, Xiao Huizhou can no longer cultivate human techniques; he can only cultivate fox or other similar types of demon beast techniques."

"Ah! But we can't find the fox clan's cultivation techniques either!"

At this moment, the Heavenly Wolf in the Lesser Thousand Worlds jumped out: "Master, I have a fox clan cultivation technique from the Immortal Realm here, which Xiao Huizhou can try out."

"I'm planning to send Xiao Huizhou into the Lesser Thousand Worlds to cultivate with Tianlang. Do you have any objections?" Yang Hongbo said.

"No, thank you so much, Great-Grandfather! Thank you, Lord Sirius!"

"Little Huizhou, the Ancestor intends for you to learn cultivation from Tianlang. Are you willing?"

"Really? Ancestor, then I can play with Lord Sirius!"

"Playing is fine, but you also need to study and learn. You can't be illiterate, understand? You want to be a great general, but you can't do that without education!"

"I understand, Ancestor. I will definitely study hard and cultivate diligently!"

Yang Huizhou happily climbed onto Lord Tianlang's back, and with a whoosh, Tianlang flew into Yang Hongbo's small world.

Yang Hongbo looked at Yang Jiuye and Liu Xiaoli, who were staring at him expectantly. "What? You can't bear to part with your child? It's not like you're separated by thousands of miles. If you miss him, just come and visit your great-grandfather. I'm letting you stay with him for a while!"

"Thank you so much, Great-Grandfather!"

"Alright, the matter is resolved. You may all leave!"

Goodbye, great-grandfather!

Goodbye, Father!

Meanwhile, in the outside world, only a hundred years had passed since the demon invasion, yet thirteen of the twenty demon armies had gone missing, meaning that sixty-five demon emperors had also disappeared.

Only the Yang family knew that of the thirteen demon armies that were wiped out, eight were destroyed by the Yang family, while the other five were destroyed by the allied forces led by the Great Hua Emperor Sect.

The Great Hua Emperor Sect acquired ten warships from the Yang family, making them incredibly powerful. They divided the ten warships into five groups, each leading a large army of over ten million immortals.

These immortals were there to deceive the demons. They first sent a large army to surround the demon army. Since the demons didn't see the warships, the demon emperors wouldn't run away at the beginning. However, the warships of the Great Hua Emperor Sect, which had disappeared into the void, had already reached the demon emperors' backs.

As the great war began, the demon army lost the initiative. The Demon Emperor and the Demon King were killed, and the remaining demon cubs became easy targets for the immortal alliance.

So this is how the five demon armies that were wiped out were completely annihilated.

On the demon side, with the sixty-five demon emperors no longer making any moves, the remaining thirty-five demon emperors also felt that their future was uncertain.

Although only a hundred years have passed since the invasion, of the remaining thirty-five Demon Emperors, only five have completed a small part of what was required, and the rest are not even halfway there.

In order to communicate with each other, the thirty-five Demon Emperors used communication jade talismans and began to discuss how to complete the mission quickly!

In the past, when the demon army invaded the immortal continent, the Demon Emperor never had to worry about his life. Now, only a hundred years later, two-thirds of the demons have already disappeared. If this continues, the demon army will be wiped out in less than two hundred years.

"Bluetooth Demon Emperor, I heard that your demon army has completed a significant portion of its mission, and your brother Bluebird is still missing! Don't you have anything to say?"

"What Mao wants to say is, he is him, and I am me. Does he expect me to avenge him just because he was killed by the immortals?"

"What should we do now? The Immortal Clan has gone to such great lengths this time. If we can't unite and work together, annihilation is all that awaits us!"

"Sigh, we can't just combine our forces, can we? Wouldn't that make an even bigger commotion?"

"Never mind, let's combine our forces and pull off a big heist. Let's get out of here while we can!"

After a lot of noise, no one came up with a useful plan, and gradually, all the Demon Emperors fell silent.
