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

Soon, the leaders of the various families gathered together. Yang Hongbo informed everyone that the war between immortals and demons was about to break out, and explained his idea of ​​uniting the smaller families and immortal sects to fight against the demons.

An elder of the Yang family frowned and said, "Patriarch, it is good to unite with other forces, but those small families and immortal sects have always been short-sighted and only care about immediate interests. They may not be willing to cooperate with us."

Another elder chimed in, "Yes, Patriarch. And even if they were willing to join forces, they might not go all out in battle, which would only hinder us."

Yang Hongbo waved his hand and said, "Elders, I understand your concerns. But now the Demon Clan is about to invade. If we don't unite, only destruction awaits us. Although those small families and immortal sects have their own problems, they are also part of the Immortal Clan. As long as we can reason with them, appeal to their emotions, and show them the power of unity, I believe they will understand the stakes involved."

Dongfang Bubai also stepped forward and said, "Elders and clan leaders, my husband is right. We can start by offering help and support to some of the clans and immortal sects we have cooperated with before, so they can experience the benefits of alliance. Then we can gradually expand the scope of the alliance, forming a powerful force to fight against the demon race together."

After some discussion, the leaders of the various families finally reached a consensus and decided to support Yang Hongbo's plan. Thus, Yang Hongbo and Dongfang Bubai began traveling around, visiting smaller families and immortal sects with whom they had good relations.

They first arrived at a small immortal sect called Qingfeng Immortal Sect. The sect leader of Qingfeng Immortal Sect was an old man named Qingfengzi, who warmly welcomed Yang Hongbo and Dongfang Bubai upon seeing them.

This sect leader is a late-stage Immortal King, and the sect has two Supreme Elders at the peak of Immortal King. The sect has over 100,000 disciples. If they could unite, they would be a formidable force!

Yang Hongbo cut to the chase, saying, "Sect Master Qingfeng, I have come here today to discuss important matters. The war between immortals and demons is about to erupt, and the demon race is about to launch a large-scale invasion of the immortal continent. Our immortal continent faces a tremendous crisis. I wish to unite all forces to jointly fight against the demon race. What is Qingfeng Immortal Sect's opinion?"

Upon hearing Yang Hongbo's words, Qingfengzi's expression turned solemn: "Patriarch Yang, I have also heard about this matter. However, our Qingfeng Immortal Sect is weak, and I'm afraid we won't be able to play much of a role in this great battle."

Yang Hongbo smiled slightly: "Sect Master Qingfeng, please don't be modest. Every force is a part of the Immortal Clan. As long as we unite, we can unleash tremendous power. Moreover, our Yang family will provide certain support and protection to the united forces, so that everyone can fight without any worries."

Dongfang Bubai also said, "Sect Master Qingfeng, think about it. If the demons invade, can your Qingfeng Immortal Sect resist alone? Not only will the sect be destroyed, but your disciples will also be slaughtered. However, if we unite, we may be able to defeat the demons and protect our homes and loved ones."

After a moment of contemplation, Qingfengzi finally nodded: "Patriarch Yang, Madam Dongfang, you are right. My Qingfeng Immortal Sect is willing to join the united forces to fight against the Demon Race."

Yang Hongbo and Dongfang Bubai smiled happily: "Great! Sect Master Qingfeng, with your addition, our strength has increased once again. Next, we will continue to visit other forces, hoping that they can also join our united camp like the Qingfeng Immortal Sect."

After leaving Qingfeng Immortal Sect, Yang Hongbo and Dongfang Bubai immediately visited several other small families and immortal sects. After some effort, they successfully persuaded these forces to join the united front.

However, their path to alliance was not without obstacles. When they arrived at a small family called the Xuanming Family, they encountered a hurdle. The patriarch of the Xuanming Family was a powerful figure known as the Xuanming Ancestor, who was arrogant and dismissive of Yang Hongbo and Dongfang Bubai's proposal.

Ancestor Xuanming's strength is only at the mid-stage of Immortal Venerable, and his clan is not large, with less than 100,000 members, most of whom are below the Immortal level. If a great battle breaks out, Ancestor Xuanming will definitely lead his clan members who are above the Immortal level to run away first!

The Xuanming Ancestor coldly said, "Clan Chief Yang, Madam Dongfang, your so-called alliance is nothing more than an attempt to use us small families and minor immortal sects to serve your Yang family. Although my Xuanming family is not as strong as your Yang family, we will not easily submit to others."

Yang Hongbo frowned, but wasn't angry. Instead, he patiently said, "Clan Chief Xuanming, you misunderstand. We've united to fight against the Demon Clan and protect our Immortal Continent. This isn't for the benefit of any one family, but for the survival of the entire Immortal Clan. If the Demon Clan invades, can your Xuanming family remain unscathed?"

Ancestor Xuanming sneered, "Hmph, although the Demon Race is powerful, my Xuanming family has its own means of survival. Even if the Demon Race invades, I may not necessarily lose."

Dongfang Bubai said, "Clan Chief Xuanming, your confidence is commendable, but the strength of the Demon Clan should not be underestimated. Each time they invade, they send out a large number of experts and elite troops. Even if your Xuanming Clan has methods to protect itself, it will be difficult to withstand the Demon Army's fierce offensive. Moreover, if other small families and immortal sects are wiped out by the Demon Clan, how long can your Xuanming Clan survive alone?"

After listening to Dongfang Bubai's words, the Xuanming Ancestor remained silent for a moment. He understood that Dongfang Bubai was right. If all other forces were wiped out by the Demon Clan, their Xuanming family would also find it difficult to survive alone.

Seeing that the Xuanming Ancestor was wavering, Yang Hongbo pressed his advantage, saying, "Clan Chief Xuanming, our Yang family will provide strong support and protection for the united forces. Moreover, in battle, we will rationally assign tasks based on the strength and characteristics of each force, so that everyone can play their maximum role. We are not trying to use you, but to join hands and fight against the demon race together."

The Xuanming Ancestor finally nodded: "Alright, Clan Chief Yang, Madam Dongfang, my Xuanming family is willing to join the alliance. But you must remember, if your Yang family dares to harbor any ill intentions, my Xuanming family will absolutely not let it go."

Yang Hongbo and Dongfang Bubai smiled happily: "Clan Chief Xuanming, rest assured, our Yang family would never do such a thing. Let's work together for the future of the Immortal Clan!"

As time went on, Yang Hongbo and Dongfang Bubai successfully united more and more families and immortal sects, forming a powerful force.

The entire alliance is centered on Immortal Dream Marsh, radiating outwards over hundreds of millions of miles, and encompassing dozens of immortal families and more than ten immortal sects. The most powerful figures in each immortal family are Immortal Venerables, with one or two per family. The most powerful figures in each immortal sect are Immortal Kings, with two to five per sect.

The reason they were willing to submit to the Yang family's management was because they had heard that the Yang family had more than one Immortal Emperor-level expert, and that there were two or three Immortal Emperor-level experts who had appeared in public.

Most importantly, behind the Yang family is a super sect—the Great Hua Imperial Sect.

Everyone began to organize joint forces for training and drills to improve their combat effectiveness and teamwork.

During training, Yang Hongbo and Dongfang Bubai repeatedly emphasized the importance of unity. They told everyone that only by uniting could they unleash their greatest strength and defeat the powerful demon race.

Finally, twenty years passed in the blink of an eye, and the war between immortals and demons broke out. The demon race's giant flying immortal ships, like black clouds, blotted out the sun and sailed towards the immortal continent. The demon army surged in like a tidal wave, their battle cries shaking the heavens and the earth.
