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

When Yang Hongbo opened his eyes again, he found himself on a battlefield. The enemy opposite him was an endless array of robots, with huge tanks moving on the land and massive warships flying in the sky.

Meanwhile, their own side consisted of a group of flying beings (Protoss), surrounded by a halo, dodging enemy attacks while using their own skills to attack the enemy.

At that moment, a voice echoed in Yang Hongbo's mind: "Congratulations, you have entered the final level. The mission for this level is to defeat the AI ​​race to complete it!"

As soon as that voice disappeared, another voice appeared: "Dear host, your system has been credited to your account. Please receive your system gift package."

Yang Hongbo hurriedly opened the system gift pack, which contained only an infinitely large storage space and nothing else.

The main function of this system is to recycle all useful items, including metals, energy crystals, spiritual herbs and medicines, demon cores, and highly valuable flesh and blood.

The points earned from recycling items can be redeemed in the system shop for any items that assist the gods in their cultivation.

At that moment, a massive surge of memories flooded Yang Hongbo's brain, nearly cracking his skull.

This world is also called the God Realm. The enemy on the other side is the Omnic Race. Hundreds of years ago, the Omnic Race discovered this God Realm. In order to conquer the God Realm, the leader of the Omnic Race sent a large army to invade the God Realm.

But how could the people of the divine realm tolerate a group of fleshless beings invading the divine realm? Thus, a fierce war of invasion and counter-invasion broke out.

The advantage of the AI ​​is that low-level robots are easy to manufacture. As long as there is no shortage of raw materials, they can continuously produce a large number of low-level robots.

The AI ​​race is divided into several classes, from low-level robots to the most powerful war stars: SSS, SS, S, A, B, C, D, E, F, with SSS being the highest and F being the lowest.

The gods have the advantage of a vast territory, a large population, and everyone possesses divine skills. The ranks of the gods are divided into: soldier, warrior, general, monarch, king, emperor, demigod, and god.

The Protoss assembled eighteen armies to resist the invasion of the Machine Race, and Yang Hongbo was the leader of one of these armies. The Protoss had a total of eighteen god-level powerhouses, and Yang Hongbo was one of them.

At this moment, Yang Hongbo hovered in mid-air, his cold gaze sweeping across the battlefield. Beside him, a god-level being clad in silver armor rushed over anxiously, saying, "Chief, the AI ​​race's offensive is becoming increasingly fierce; our defenses are stretched thin!"

Yang Hongbo frowned slightly and said in a deep voice, "Don't panic. Pass on my orders to have each squad strengthen their cooperation, use their divine skills to first defeat their low-level robot swarms, and then concentrate their forces to deal with the high-level tanks and warships."

"Yes!" The Emperor-level god accepted the order and left.

Before long, the Protoss warriors on the battlefield coordinated with increasing ease, flashing brilliant divine skills as low-level robots fell like wheat being harvested. However, the AI ​​race quickly adjusted their tactics, sending more advanced vehicles and warships forward, unleashing powerful energy attacks.

"Chief, this can't go on. Their protective shields are too strong, and our attacks are not very effective." Another demigod flew over, his face full of worry.

Yang Hongbo's gaze was deep. After a moment of contemplation, he said, "The AI ​​race's protective shield is strong, but not invincible. The larger their size, the stronger the shield's protective power, but at the same time, the greater the energy consumption. Let's concentrate our forces and attack their energy supply lines first."

"But how do we find their energy supply lines?" asked the demigod.

Yang Hongbo's lips curled up slightly. "I have my own way. Pass on my order: send out all the Protoss warriors skilled in perception to find the weak points in the AI ​​race's energy supply."

"Yes, sir!" The demigod-level god quickly relayed the order.

Soon, a group of Protoss warriors skilled in perception darted across the battlefield like nimble birds. A short while later, one of the perception-skilled Protoss warriors excitedly flew back to Yang Hongbo's side, "Chief, I've discovered their main energy supply line, right behind that cluster of war machines."

A resolute glint flashed in Yang Hongbo's eyes. "Alright, gather all soldiers of general rank and above, and come with me to sabotage their energy supply lines."

A group of powerful Protoss warriors quickly assembled, and at Yang Hongbo's command, they charged towards the rear of the tank formation like arrows released from a bow. The AI ​​race seemed to have sensed the Protoss's intentions and immediately dispatched a large number of advanced robots and warships to intercept them.

"Everyone be careful, don't linger in the fight, head straight for the target!" Yang Hongbo shouted.

The powerful gods, relying on their superior skills and powerful divine abilities, fought their way through the enemy's obstruction. A Sovereign-level god warrior wielded a massive battle axe, cleaving several advanced robots in his path into pieces; a King-level god warrior unleashed a powerful fire divine ability, burning a warship to the ground.

However, as they approached the energy supply line, a massive protective shield appeared before them. This shield emitted a ghostly blue light, clearly a powerful defense erected by the omnics to protect the energy supply line.

"This protective shield is very powerful. How can we break through it?" a royal-level god warrior asked, frowning.

Yang Hongbo carefully observed the protective shield, and suddenly his eyes lit up. "Look, everyone, the energy fluctuations of the protective shield are regular. We can concentrate our attack when its energy is at its weakest."

Everyone nodded in agreement, ready to attack. When the energy fluctuations of the protective shield reached their weakest point, Yang Hongbo shouted, "Attack!"

The powerful beings of the divine race simultaneously unleashed their mighty divine techniques, beams of light shooting towards the protective shield like meteors. Under the powerful attack, the shield finally cracked, and then shattered with a deafening roar.

"We did it!" the Protoss warriors cheered.

But their joy was short-lived. Suddenly, a war star of the Omnic race appeared above the realm of the gods, unleashing a powerful beam of energy that hurtled towards the warriors.

"Oh no, it's a War Star from the AI ​​race!" Yang Hongbo's expression changed.

"Chief, what do we do now? The War Star's attacks are too powerful; we can't defend against them at all," a general-level Protoss warrior said anxiously.

Yang Hongbo took a deep breath and calmly said, "Everyone, don't panic. I will withstand its attack and draw the attack of the war star. You all follow behind me and look for opportunities to concentrate your attacks on this war star."

"Yes!" The powerful members of the Divine Race quickly hid behind Yang Hongbo and rushed towards Zhanxing.

Yang Hongbo held up his shield, drawing the attack power of the war star. The war star continuously released energy beams, but they were all blocked by his powerful shield.

"Now!" Yang Hongbo shouted, seizing the opportunity.

All the powerful members of the Divine Race simultaneously unleashed their strongest divine techniques, attacking the War Star. Under the powerful assault, the War Star's protective shield began to flicker erratically, and finally shattered with a deafening roar.

"We did it!" Yang Hongbo shouted excitedly.

"Now's the time to launch a full-scale counterattack!" Yang Hongbo gave the order, and the Protoss warriors surged towards the Omnic race like a tidal wave.

Under the fierce attack of the Protoss warriors, the Omnic defenses gradually collapsed. Low-level robots were wiped out in large numbers, and high-level vehicles and warships were destroyed one by one.

After a fierce battle, the invading Omnic forces were finally repelled. The Protoss warriors cheered and celebrated this hard-won victory.

"Chief, our victory this time is all thanks to your brilliant command," a Divine Race warrior of Emperor rank said admiringly.

Yang Hongbo smiled and shook his head. "This is the result of everyone's joint efforts. However, we cannot let our guard down. The AI ​​race will definitely not give up easily, and we must prepare for the next invasion."

"Yes, Chief!" the Protoss warriors replied in unison.

Since then, under Yang Hongbo's leadership, the Protoss have continuously strengthened their power, developing new divine skills and tactics. At the same time, they have actively sought out the weaknesses of the Omnic race, preparing to completely defeat them.

Months later, the AI ​​race returned. This time, they were more powerful than before, bringing with them even more advanced robots and warships.

"Chief, the Omnic race's offensive is even more intense than last time. How should we deal with it?" a general-level Protoss warrior asked anxiously.

Yang Hongbo's gaze was firm. "Don't be afraid, everyone. We are fully prepared. According to the previous plan, each group should act quickly."

The Protoss warriors swiftly deployed according to plan, employing newly developed divine skills and tactics to engage in fierce combat with the Omnics. During the battle, Yang Hongbo discovered that the Omnics' energy core had undergone a new change, becoming even more difficult to destroy.

"It seems we need to find new ways to destroy their energy core," Yang Hongbo muttered to himself.
