More than half of the sky of the ranch was scorched red as if even the air was twisting and burning under the high temperature.

Du Lu's body continued to expand.

His dragon teeth, claws, and wings became longer and sharper, emitting a dangerous aura.

Every dragon scale on Du Lu's body flickered with a strange light, like pieces of gemstones.

Looking at the system interface, Joelson saw Du Lu's combat power jumping up crazily like a rocket.

Finally, it stopped at 28,900!

His combat power was close to 30,000, and his strength was close to three times that of a 9th rank.

If Joelson's estimation was not wrong, the average saint-rank's combat power was above 10,000.

Most of them were below 15,000, and close to 15,000 were already very powerful saint-rank powerhouses.

Cliff of the Dark Church should only have a little more than 10,000 combat power.

Harriet's combat power should be around 13,000.

The legendary monster Fenrir's combat power was also close to 13,000.

And now, Du Lu had just advanced to the saint-tier, and his combat power had soared to nearly 30,000.

It was twice that of an ordinary saint-tier.

Joelson suddenly felt particularly happy, and the Damocles swords hanging above his head disappeared.

Even if he returned to the southern region now, he would still be invincible with Du Lu!

"Roar!"

A low roar sounded.

A dark figure pounced towards Du Lu in the sky.

It was the steel dragon.

Although it was cold, it was extremely proud.

It and Du Lu had always been competing with each other. Now That Du Lu had advanced to the saint-level, the steel dragon could not hold back anymore. It wanted to see how big the gap was between itself and Du Lu.

Du Lu's body was originally one size bigger than the steel dragon's.

After advancing, it was more than three times the size of the steel dragon.

However, Du Lu and the steel dragon's combat strength were similar. If the steel dragon won the fifth battle, it could still firmly suppress Du Lu.

But now...

Facing the steel dragon's attack, Du Lu's dragon claw, which was attached to the flames, fiercely slapped the steel dragon's body.

It easily sent the steel dragon flying.

Moreover, the flames remained on the steel dragon's body and were still burning. The steel dragon's metal body seemed to be on the verge of melting.

The difference was too big.

Du Lu, who was after the saint level, could no longer control the flames that the steel dragon could resist.

The steel dragon's personality was even more arrogant than Du Lu's. It wanted to charge forward but was stopped by Joelson.

Du Lu was very proud. He looked down at the steel dragon with contempt as if to say, "See, I'm still the strongest dragon under Master!"

The steel dragon growled a few times, its dark golden eyes filled with unwillingness.

Joelson caressed its cold body and said with a smile, "Don't worry, you will have such a day soon."

Joelson expanded six more farms and upgraded half of them to advanced level. Above that was the farm.

Next, Joelson would feed most of the farm crops to the steel dragon so that the steel dragon could be promoted to saint-level as soon as possible.

The cultivation of electric dragons and lightning should also be promoted as soon as possible.

The terrifying destructive power of the Lightning was destined to be one of Joelson's powerful helpers in the future.

Du Lu descended from the sky, and Enny and the cloud dragon quickly went up to meet him.

Enny's eyes were gentle, and the cloud dragon worshipped Du Lu.

Du Lu was now the most powerful character in its heart besides Joelson.

After advancing to saint-level, Du Lu no longer produced gold coins, but magic crystal coins.

It produced 50 magic crystal coins per minute.

The maximum daily magic crystal coins output of a large fire-type dragon nest was 10,000 magic crystal coins.

The income was many times more than before.

Looking at Du Lu's huge body, the volcano that had already upgraded to a large fire-type dragon nest seemed to be unable to contain it.

He was considering whether he should give Du Lu a bigger home.

After inquiring about the price of upgrading the super large dragon nest, he immediately dismissed this idea.

A full million magic crystal coins!

Converted into gold coins, it was 100 million.

And it was far more than that because very few people would use even more precious magic crystal coins to exchange for gold coins.

Even for the current Joelson, it was an astronomical figure.

The super-large fire-type dragon nest could no longer be described as a nest. According to the system's introduction, if it was a fire-type dragon nest, the super-large dragon nest would form a chain of volcanoes.

Even if Joelson was rich, the area of the ranch was not big enough.

"It's time to expand the ranch," Joelson said to himself.

The first expansion of the ranch did not require much money. It only required 100,000 gold coins.

Joelson clicked on the expansion.

The next moment, a dazzling light fell from the sky.

The clouds that lingered on the side of the floating island quickly dissipated. Countless amounts of soil appeared out of thin air from below, connecting to the edge of the original floating island.

Half a minute later, the floating island was at least 30% larger than before.

It was an extremely magical scene. Every time the ranch was built, Joelson could not help but exclaim.

The constructed soil, water, and metal seemed to appear out of thin air. It was very magical.

The expanded floating island immediately became spacious again.

"Congratulations to the rancher for successfully expanding the ranch. Obtained 5000 experience points."

With the experience gained from Du Lu's advancement, Joelson could already be promoted to a tier 9 mage.

Joelson was overjoyed. At this moment, the system's voice sounded again.

"The rancher has a saint-level dragon. The ancient ruins have been unlocked."

Joelson was stunned and had yet to react.

Next to the Dragon God Colosseum, there was a loud noise from the ground, and two black stone pillars slowly rose from the ground.

The black stone pillars rose to a height of more than twenty yards and stopped, and complex and profound golden runes lit up on the stone pillars.

The space in the middle of the stone pillars quickly collapsed, and a dark blue vortex formed in front of Joelson.

At the entrance of the ancient ruins.

"Ancient ruins?!"

Joelson blinked his eyes and asked, "What's inside the ruins?"

"The precious runes that help the rancher's dragon to truly restore the glory of the ancient dragon race." The system explained.

Joelson turned around, and Du Lu, who had grown in strength, stared at the entrance, his eyes filled with eagerness.

Du Lu was very strong now, and he was very confident in his own strength.

Joelson hesitated for a while, before asking, "Then can we enter now?"

The system replied in a cold and emotionless voice, "The rancher's strength has been detected to be on the low side. It is not recommended to follow him in. It is recommended that the dragons explore on their own."

"So, I can enter as well."

A level 8 strength was actually judged to be low by the system. Just how dangerous was this ancient ruin?

Joelson suddenly realized something and asked, "If one were to be injured or die in the ancient ruin, would it be..."

"Yes."

Hearing the system's affirmative answer, Joelson's heart sank.

It was not like the Dragon God Arena. If he could not win, he would admit defeat, and the ancient Dragon Soul would not take the initiative to attack again.

Did this mean that after the saint-level, the giant dragon needed to leave the hotbed and enter the cruel and bloody training field?
