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

The Elders of the Immortal Clan Alliance Headquarters exclaimed, "What? Only 10 billion top-grade immortal crystals? This price is simply too good to pass up!" The First Elder was filled with excitement, as if he could already see the Great Hua Imperial Clan dominating the battlefield with these advanced warships.

Soon, Zhang Lingfeng arrived at Dongfang Bubai's alchemy room again, carrying the sect's decision.

"Disciple, the sect has decided to purchase four advanced warships first," Zhang Lingfeng said to Dongfang Bubai with a joyful expression.

Dongfang Bubai smiled and nodded: "Master, I will contact my husband right away."

She took out the communication jade talisman again and connected with Yang Hongbo: "Husband, the sect has decided to buy four advanced warships first."

Yang Hongbo's cheerful voice came through: "No problem, wife, I'll arrange for the family to make preparations right away."

"Honey, you're so fast!" Dongfang Bubai said coquettishly.

"Of course, I'll definitely handle anything my wife asks me to do as soon as possible. But you can't just say 'my husband is fast' to me casually!" Yang Hongbo laughed. "However, wife, although our family's warships are affordable, they are also in limited supply, after all, they weren't easy to obtain."

[These warships were certainly hard-won, as they required points for a lottery. It was only during this period, by forming a family alliance and earning a considerable number of points, that we were able to participate in the lottery; otherwise, it would have been quite difficult!]

"Okay, my husband is the best," Dongfang Bubai said sweetly.

After hanging up the call, Dongfang Bubai said to Zhang Lingfeng, "Master, my husband has agreed to make the arrangements."

Zhang Lingfeng nodded in satisfaction: "Disciple, you have rendered a great service to the sect this time. Once the warship is acquired, the sect will surely reward you handsomely."

"Master, this is what I should do, and it's also for the peace of the Immortal Realm," Dongfang Bubai said modestly.

At the same time, the higher-ups of the Great Hua Imperial Sect were also making intensive preparations to sell low-level warships to other top sects.

The sect leader summoned several core elders and discussed, "Now that we have advanced warships, these lower-level ones are not very useful. We might as well sell them to other sects and exchange them for some resources."

An elder chimed in, "The sect leader is absolutely right. Moreover, we can use this opportunity to improve relations with other sects and support each other during the war between immortals and demons."

"So, which sect do you all think should we leak the news to first?" the sect leader asked.

After a moment's thought, another elder said, "I think we can start with the Xuantian Immortal Sect, which has a good relationship with us. They are quite strong and have always stood on the same side as us."

"Alright, let's contact the Xuantian Immortal Sect first," the sect leader decided.

Soon, the Great Hua Imperial Sect dispatched an envoy to the Xuan Tian Immortal Sect. Upon meeting with Yang Zaiqian, the sect leader of the Xuan Tian Immortal Sect, the envoy went straight to the point: "Sect Leader Yang, our Great Hua Imperial Sect recently acquired a batch of high-level warships and now wishes to dispose of some lower-level ones. We wonder if your sect would be interested?"

Yang Zaiqian, the sect leader, brightened up: "Oh? I wonder what the performance of your sect's low-level warships is like?"

The envoy smiled and said, "Sect Master Yang, the Xuantian Immortal Sect also has two warships, which should be the same as our batch of low-level warships. Sect Master Yang should also know the performance of his warships."

Yang Zaiqian's heart stirred slightly, and he asked, "What about the price?"

The envoy held up one finger: "One ship worth 10 billion top-grade immortal crystals."

The sect leader of the Xuantian Immortal Sect frowned: "This price seems a bit high."

The envoy quickly explained, "Sect Master Yang, this is already a very reasonable price, and our Great Hua Imperial Sect can also provide certain after-sales services, such as repairs and maintenance."

After pondering for a moment, Yang Zaiqian Sect Master said, "How about this, I'll buy three first and see how the combined combat power of five warships is."

The envoy was delighted: "No problem, Sect Master Yang is truly straightforward. Then let's draw up a contract, cash on delivery."

Soon, a few days later, the two sides completed the transaction. Sect Master Yang Zaiqian looked at the three warships in his hands and nodded in satisfaction: "With these warships, the strength of our Xuantian Sect will be greatly enhanced."

The envoy smiled and said, "Sect Master Yang, I hope that our two sects can join hands in the war between immortals and demons and defeat the demon army together."

"That's for sure. Our Xuantian Immortal Sect and the Great Hua Imperial Sect have always been allies, so we should stand together through thick and thin," Sect Master Yang Zaiqian said firmly.

After completing his mission, the envoy hurriedly returned to the Great Hua Imperial Sect to report. The sect leader was delighted to learn that the Xuan Tian Immortal Sect had purchased three low-level warships: "Excellent! Next, we'll contact other sects."

Subsequently, the Great Hua Imperial Sect sold low-level warships to several top sects, and everyone was satisfied with the deal. The Great Hua Imperial Sect gained a large amount of resources and disposed of unwanted items, while other sects obtained practical war equipment, making it a win-win situation.

A few days later, the Yang family delivered four advanced warships to the Great Hua Imperial Sect. The high-ranking officials of the Great Hua Imperial Sect looked at the four imposing warships with excitement and anticipation in their eyes.

The sect leader personally boarded a warship, feeling its powerful aura, and exclaimed, "This advanced warship is indeed extraordinary. With them, our Great Hua Imperial Sect will surely be invincible in the war between immortals and demons."

"In the past, although our low-level warships could kill Demon Emperors, those Demon Emperors couldn't just stand still and let our Immortal Emperors and warships get close to them."

"This time it's different. We can control advanced warships and shove them right in the face before firing, or even in their rear ends. Hahaha, just thinking about it is fucking awesome!"

An elder excitedly said, "Yes, Sect Master, let's pilot these warships to conquer the demon army and show them the might of our Great Hua Imperial Sect."

The sect leader nodded: "Alright, pass on my order: all disciples of the sect shall board the warships and prepare for the expedition."

Soon, the disciples of the Great Hua Imperial Sect boarded four advanced warships and a large number of giant flying boats, and flew in a grand procession toward the encampment of a certain demon army.

When they arrived at the demon army's encampment, the demon army was clearly unprepared for the sudden attack by the Great Hua Emperor Sect. Seeing the approaching Immortal Alliance army, the demon cubs showed expressions of terror.

The five Demon Emperors in this demon army, watching the approaching Immortal Alliance, cursed angrily: "Has the Great Hua Imperial Sect gone mad? To mobilize such a large force! Luckily they didn't deploy warships, or we would have had to run away!"

At this moment, the sect leader of the Great Hua Emperor Sect stood on the warship that had vanished into the void and loudly ordered, "All disciples, give it your all!"

With the order given, four advanced warships launched the first attack. They had already arrived behind the five Demon Emperors' flagships, and the crystal energy cannons on the warships were already aimed at the Demon Emperors' flagships.

The deafening roar of cannons echoed through the sky, instantly reducing the flagship carrying the Demon Emperors to rubble. Even the nearby flying ships and the Demon Army were wiped out by the aftershocks of the explosion.

The demon soldiers scattered in panic, but the disciples of the Great Hua Imperial Sect gave them no chance to escape. The disciples followed closely behind, unleashing a barrage of attacks that knocked the demon cubs to their deaths.

On the battlefield, swords flashed and skills crisscrossed. Beams of light, some missing their targets and others piercing through them but still possessing some power, shot straight into the distant sky. It was truly a scene of countless silver flowers blooming everywhere. Who knows when the demons will fall!

After a fierce battle, the demon army was completely annihilated. Not only were the Demon Emperor and Demon King wiped out, but dozens of flying ships were also captured. The disciples of the Great Hua Imperial Sect cheered and celebrated their victory.

Standing atop the warship, the sect leader gazed upon the annihilated demon army, his heart filled with heroic ambition: "With these advanced warships, our Great Hua Imperial Sect will surely achieve the greatest victory in this war between immortals and demons."

An elder approached the sect leader and respectfully said, "Sect leader is wise. With these advanced warships, the strength of our Great Hua Imperial Sect has far surpassed that of other super sects, making us a true pillar of the Immortal Realm."

The sect leader smiled and nodded: "This is just the beginning. We must continue to work hard, constantly improve our strength, and fight for the peace of the Immortal Realm."
