After more than ten years on the mountain, you will become invincible when you come down.

The Red Dragon King's decadent eyes gradually became firm.

"Lu Feng, I want to bet with you again!" said the Red Dragon King firmly.

Lu Feng looked at the Red Dragon King with interest and said calmly, "But you, the Red Dragon clan, have nothing left. What do you have to bet with me?"

"Yes, we, the Red Dragon Clan, do not have the Fire Dragon Balls, and we have no resources, but we still have so many Red Dragons. I'm betting on the fate of our Red Dragon Clan! I will fight with you, and if I lose, our Red Dragon Clan will submit to you and serve you as their master! If I win, the Fire Dragon Balls and resources will still belong to our Red Dragon Clan!" said the Red Dragon King in a deep voice.

Lu Feng narrowed his eyes slightly, looked at the Red Dragon King, and a faint smile appeared at the corner of his mouth.

"Okay, I accept your bet. However, if you lose again this time, your Red Dragon clan will never have a chance to turn things around." Lu Feng agreed.

The Red Dragon King took a deep breath, and a hint of determination flashed in his eyes.

He knew it was a desperate gamble, but he had no choice.

The battle entered a white-hot stage as soon as it began. The Red Dragon King put all his life's strength and went all out to engage in a thrilling duel with Lu Feng.

Each of his moves contained endless power and murderous intent, which shocked people.

However, despite the Red Dragon King's best efforts, he found himself still powerless against Lu Feng.

Lu Feng's strength far exceeded his imagination. No matter how hard he tried, he could not break the opponent's defense.

Gradually, the Red Dragon King fell into a passive situation and began to be suppressed by Lu Feng.

As time went by, the Red Dragon King's physical strength was gradually exhausted, but Lu Feng still maintained strong combat effectiveness.

Finally, after a fierce attack, the Red Dragon King could no longer resist and fell to the ground.

The fierce battle ended here, and Lu Feng defeated the Red Dragon King with absolute advantage.

"I accept the defeat. From now on, the Red Dragon Clan will be under the command of Lu Feng, with Lu Feng as the leader!" The Red Dragon King lowered his proud head.

Lu Feng looked at the surrendered Red Dragon Clan and felt a sense of accomplishment in his heart.

Not only did he obtain the Fire Dragon Ball and the resources of the Red Dragon Clan, he also gained a powerful force.

The Fire Dragon Clan also lowered their heads. They knew that from now on, they had already submitted to the human race in front of them...

"Red Dragon King, do you feel wronged for submitting to me?" Lu Feng asked with a smile.

"Reporting to the master, the master has such strength at such a young age. It is an honor for our Red Dragon clan to be able to submit to the master. I hope the master will not despise our Red Dragon clan and accept us!" said the Red Dragon King.

"Okay, I'm adaptable. Don't worry, since your Red Dragon clan has surrendered to me, I won't treat you unfairly. I will only take half of your Red Dragon clan's resources, and you can use the rest at your own disposal..." Lu Feng said.

The eyes of all the dragons of the Red Dragon Clan lit up. Lu Feng was able to leave them half of the resources, which was already a blessing in disguise...

"Thank you, master!" the dragons shouted in unison.

Lu Feng nodded in satisfaction, and then said, "Take a good rest, and in three days, go to the Black Dragon Clan and seize the Black Dragon Ball!"

The Red Dragon King was stunned. It seemed that Lu Feng was determined to collect all seven dragon balls...

The Red Dragon King began to prepare for the battle three days later. Since he had already surrendered to Lu Feng, he had to show his own value...

"Xiaolong, you were once a black dragon. You should know something about the black dragon's strength. I'm afraid that what happens next won't be that easy..." Lu Feng turned around and said to Xiaolong.

“Master, the strength of the Black Dragon is second only to the Golden Dragon, but now with the addition of the Red Dragon clan, I am confident that I can defeat the Black Dragon clan…” Xiaolong said confidently.

"It's a good thing to have confidence, but you still have to prepare well. There are still three days left, so you should refine the Fire Dragon Ball as soon as possible..." Lu Feng said.

For the next three days, Xiaolong spent time refining the Fire Dragon Ball.

Three days passed in a flash, and Xiaolong successfully refined the Fire Dragon Ball...

At this time, Xiaolong possessed the Water Dragon Ball, the Fire Dragon Ball, and the Silver Dragon Ball...

Three days later, Lu Feng led the Blue Dragon Clan, the Red Dragon Clan, and the Silver Dragon Clan towards the Black Dragon Clan...

Lu Feng and his group arrived at the territory of the Black Dragon clan. The Black Dragon clan felt threatened and were on high alert.

"Are you here for the Black Dragon Ball?" the Black Dragon King asked coldly.

"Since you know, just hand over the Black Dragon Ball. This will be simple and convenient for everyone..." Lu Feng said.

"Hmph! If you want the Black Dragon Ball, then come and get it with your own ability! The Black Dragon Ball is here with me, and if you want the Black Dragon Ball, you have to kill me first!" The Black Dragon King snorted coldly.

"Since you don't know whether to live or die, let's fight!" Lu Feng said in a deep voice.

The Black Dragon King was huge and exuded a powerful aura. It flew out and pounced directly towards Lu Feng.

Neither Lu Feng nor the Black Dragon King held back at all. They exerted their strength to the fullest, and each attack contained enormous energy.

The Black Dragon King opened his bloody mouth and spewed out a black flame, trying to devour Lu Feng.

Lu Feng used his teleportation skill to avoid the Black Dragon King's attack, appeared behind the Black Dragon King, and stabbed the Black Dragon King in the back with a sword.

The Black Dragon King reacted quickly, turned around and blocked Lu Feng's sword with his dragon claw, while waving his other claw towards Lu Feng.

Lu Feng used the teleportation skill again to avoid the Black Dragon King's attack, then appeared above the Black Dragon King's head and stabbed the Black Dragon King's eyes with a sword.

The Black Dragon King closed his eyes and blocked Lu Feng's sword with his eyelids, while sweeping his tail across in an attempt to knock Lu Feng away.

Lu Feng dodged the Black Dragon King's tail by leaning sideways, then swung his sword at the Black Dragon King's abdomen.

The Black Dragon King felt pain and roared, a cloud of black smoke came out of his mouth, covering Lu Feng.

Lu Feng fell into darkness and lost his sense of direction.

But he did not panic. Instead, he closed his eyes and continued to attack based on his perception of the Black Dragon King.

The Black Dragon King was not to be outdone, and continued to spit out black flames and smoke, trying to trap Lu Feng.

The battle between the two sides became more and more intense. The surrounding space was distorted by their power, forming cracks.

The whole world seemed to be shaking, as if it was about to collapse.

The little dragon saw the right moment, flew into the air, and blazing flames spewed out of its mouth.

The Black Dragon King dodged sideways, then opened his mouth and spurted out a black whirlwind, heading straight for the little dragon.

Xiaolong showed no sign of weakness. He mobilized the power of the three dragon balls, transforming them into a three-colored beam of light, which collided with the black whirlwind, making a shocking noise.
