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

On the other side, the warships that were flanking the demon army also achieved victory. Under the fierce attack of the warships, the demon army was unable to mount an effective counterattack and was wiped out one after another.

Standing atop the warship, Yang Hongbo surveyed the one-sided battlefield and burst into laughter. He said to Sect Master Shi, "Sect Master Shi, you see, the demon army's strategy of launching attacks from multiple directions is utterly ineffective. Before our warships, they are like lambs to the slaughter, utterly powerless to resist."

The sect leader smiled and said, "Clan Chief Yang is wise. The demon army used to be so powerful on the Immortal Continent because our Immortal Clan didn't have warships like these to concentrate our forces against them. Now, they've come to our ambush site; they'll taste our might!"

After this battle, the morale of the demon army plummeted. They had originally thought that a scattered attack would catch the immortal army off guard, but instead, they were routed by the immortal army.

A demon cultivator said dejectedly, "Demon Emperor, are we simply no match for the immortal army? If this continues, we'll all die here."

The Demon Emperor sighed and said, "Alas, I didn't expect the Immortal Clan's army to be so powerful. We've really bitten off more than we can chew this time. However, we demons will never admit defeat easily. Issue my order for all cultivators to retreat to the Demon Clan's main camp, and we will revise our battle plan."

The demon army began to retreat. Watching their retreating figures, Yang Hongbo ordered a pursuit. However, he only ordered his warships and airships to keep the demon army at a distance, using crystal energy cannons to attack them. If they sent anyone to cover their retreat, he would send his own people out for training.

Yang Hongbo also realized that his side had far too few people. The Yang family and the Great Hua Emperor Sect together only had 28 million people, which was the population of a small city. They needed to build a bridgehead here to counterattack the Demon Continent.

In the days that followed, the Immortal army established a formidable defensive line on the Demon continent. They repaired the cities damaged during their attack on the Demons, built new strongholds, and, taking advantage of their airships' ability to penetrate the void, dispatched ten airships as scouts to conduct comprehensive reconnaissance of the Demon continent.

After returning to their base, the demon army was also working diligently to formulate a new battle plan. They knew that to defeat the immortal army, they needed to devise a more comprehensive strategy.

One day, the demon elder in black robes summoned the demon emperors once again. He slowly said, "Gentlemen, after some time of reflection, I have devised a plan to deal with the immortal army. We can utilize the terrain of the demon continent to set up traps and ambushes. Once the immortal army enters our traps, we will launch a surprise attack, catching them completely off guard."

The Demon Emperors rolled their eyes and said, "Elder, your plan is brilliant! Our Demon Continent has a complex terrain with many places suitable for setting traps and ambushes. But didn't you see that the Immortal Clan's warships can enter the void? They don't need to pay attention to those traps and ambushes at all; they can just attack us from the void."

The demon clan leaders immediately launched into a tirade of mockery, leaving the elder red-faced and speechless.

At this moment, one of the demon emperors said, "Gentlemen, I have a plan, but I don't know if it will work?"

The other demon emperors all looked at him, waiting for him to continue.

The Demon Emperor continued, "I've heard that these warships require a large amount of top-grade immortal crystals to fly and use their crystal cannons."

"We can send small groups of troops to attack them multiple times. I don't believe they would bring a lot of fairy crystals when they come all the way from the ocean to us."

"Once their reserves of immortal crystals reach a critical point, their warships will become toothless beasts, and then it will be the world of our demon race!"

"That's great! Our Demon Continent has a large demon population, while these invading immortals seem to number less than thirty million. We can teach them a lesson then!"

The Demon Emperors all agreed, finding the method feasible. Thus, the Demon Race began to change its tactics, sending only one or two million demons to attack the Immortal Race's army each time.

When the Demon Clan first dispatched two million demon cultivators to attack the Immortal Clan's defenses, the news quickly reached Yang Hongbo's ears. Upon hearing this, a glint of excitement flashed in Yang Hongbo's eyes. He immediately summoned his family members and disciples of the Great Hua Imperial Sect, loudly proclaiming, "The Demon Clan is attacking, but this time they've only sent two million. This is a great opportunity for us to train! Everyone, prepare for battle!"

Upon hearing this, the members of the Yang family and the disciples of the Great Hua Imperial Sect were immediately filled with excitement. They had long yearned to improve their strength in actual combat, and now that the opportunity had arrived, they were all eager to try their skills.

Even Yang Hongbo allowed his wife and children to go out and fight, because he would send Tianlang and Yang Huizhou, both at the Immortal Emperor level, to guard them.

As the demon cultivators approached the immortal cultivators' defensive line, Yang Hongbo gave the order, and some warships and airships began to circle in the air, assuming an attack posture, but did not immediately launch a fierce attack. Meanwhile, members of the Yang family and disciples of the Great Hua Imperial Sect rushed out from the defensive line and charged towards the demon cultivators.

A young member of the Yang family, wielding a longsword, charged towards a demon cultivator, shouting, "Demon scum, prepare to die!" The demon cultivator, not to be outdone, brandished his demonic blade and met the attack. The two instantly clashed, their swords flashing. Although the young member lacked experience, he gradually gained the upper hand thanks to his courage and the advantages of his immortal cultivation techniques. Seizing his opportunity, he thrust his sword towards the demon cultivator's chest. The demon cultivator, unable to dodge, was struck and fell to the ground with a scream.

Encouraged by this scene, a disciple from the Great Hua Emperor Sect charged even more fiercely at the other demon cultivator. He unleashed a powerful immortal technique; a flash of light struck the demon cultivator, causing him to stagger. Seizing the opportunity, the disciple pressed forward with another ruthless attack, slaying the demon cultivator with his sword.

The demon cultivators were few in number, and under the fierce attack of the Yang family members and disciples of the Great Hua Emperor Sect, they were quickly overwhelmed. They had originally thought that their one or two million people would be enough to force the immortal race to use their flying ships, but they hadn't expected that the immortal race had no intention of deploying flying ships at all. However, the warships and flying ships circling them menacingly in the sky filled them with pressure.

Seeing the situation was dire, a demon squad leader shouted, "Don't panic! Everyone, concentrate your efforts and break through one point first!" Upon hearing the order, the demon cultivators began to rush towards a weak point in the immortal clan's defenses.

Seeing this from the air, Yang Hongbo sneered and said to Sect Master Shi, "Sect Master Shi, they still want to break through our defenses? They're dreaming. Let the warships and airships teach them a lesson."

The sect leader nodded, and Yang Hongbo ordered the warships and airships to launch an attack. Barrages of crystal energy cannon fire erupted from the warships and airships, blasting towards the demon cultivators. The demon cultivators were instantly engulfed in flames, screaming in agony. They hadn't expected the immortal race's attack to be so fierce, and their original plans were instantly disrupted.

After a fierce battle, most of the two million demon cultivators were annihilated, with only a few escaping back to the demon's main camp. The Yang family members and disciples of the Great Hua Imperial Sect cheered with joy. They had gained a great deal from this battle, not only improving their combat skills but also boosting their confidence.

Looking at his disciples' excited expressions, Yang Hongbo smiled and said, "You all did a great job. This is the purpose of our training: to grow through real combat. In the future, if the demons send small groups to attack again, we must strike them hard, just like we did today."

The Yang family disciples responded in unison, "Yes, Clan Leader! We will certainly live up to your expectations!"

Not long after, the Demon Clan sent another 2.5 million cultivators to attack. Yang Hongbo used the same tactic as before, deploying warships and airships to create a deterrent effect in the air, and then sending members of the Yang family and disciples of the Great Hua Imperial Sect into battle.

This time, the demon cultivators learned from their previous mistakes and became even more cunning. Instead of concentrating their attacks on a single point, they dispersed and attempted to break through the immortals' defenses from multiple directions.

A group of demon cultivators stealthily circled around to the flank of the immortal clan's defensive line, preparing to launch a surprise attack. However, their actions had already been discovered by a disciple of the Yang family. The disciple immediately sent a signal to his nearby companions. A group of Yang family members quickly arrived and surrounded the demon cultivators.

Enraged at being discovered, the demon cultivators brandished their weapons and attacked relentlessly. However, the Yang family members coordinated perfectly, alternating between offense and defense, leaving the demon cultivators helpless. After a fierce battle, the demon cultivators gradually became exhausted and were killed by the combined efforts of the Yang family members.

Elsewhere, disciples of the Great Hua Imperial Sect also engaged in fierce battles with the demon cultivators. They unleashed various immortal techniques, driving the demon cultivators into a retreat. Although the demon cultivators fought valiantly, they ultimately could not withstand the powerful offensive of the immortals.

In this small-scale trial, Yang Hongbo's wives and hundreds of children and grandchildren were the most dazzling, because among them were Dongfang Bubai, who was at the Immortal King Realm, and Tianlang and Yang Huizhou, who were at the Immortal Emperor Realm.

During the battle, they charged towards the most difficult demon forces, unleashing dazzling spells upon them, while a group of old men secretly set up formations around the demons.

When the demons discovered this, they were already trapped in a maze of formations and spells, and no matter how much they struggled, they could not escape their fate of death.

After the battle, the demon race's 2.5 million cultivators were once again slain. While some members of the Yang family and disciples of the Great Hua Imperial Sect were also injured, the overall casualties were not significant. Looking at the corpses of the demon cultivators scattered across the ground, they were filled with pride.

Looking at his family disciples, Yang Hongbo said with satisfaction, "You all performed exceptionally well this time. The demons thought sending a small force would weaken us, but it turned out to be an excellent training opportunity for us. We must maintain this momentum, and once we are strong enough, we will launch a counterattack on the demon continent and utterly defeat them!"

Hearing Yang Hongbo's words, the disciples became even more determined. They knew that the battles to come would be even fiercer, but they were confident that, under Yang Hongbo's leadership, they would defeat the demons and protect the glory of the immortal race.

After several failed small-scale attacks, the demons began to re-evaluate their strategy. However, what they didn't know was that each of their attacks was accumulating strength for the immortals' counterattack, and an even greater storm was quietly brewing.
