Naruto: After slagging F4, he was caught

However, he also knew that the real challenge was yet to come.

The threat from the Otsutsuki clan and the Shura clan always exists, and they must always be vigilant.

"I am very satisfied with your progress, but don't be complacent." Zulong said seriously, "The enemy is stronger than we thought, we must continue to improve our strength. Next, I will assign you more difficult tasks so that you can continue to hone your skills in actual combat."

The four nodded firmly, knowing that they had a great responsibility on their shoulders. In order to protect Yaoyao and the ninja world, they were willing to make every effort.

Under Zulong's arrangement, the four began a new challenge.

They went deep into the dangerous areas of Xuantian Continent and fought against various powerful enemies.

In this process, they constantly adjusted their combat strategies to maximize the power of natural treasures.

As the battle progressed, their cooperation became more and more tacit.

Madara's Fire Field can provide cover for teammates, Izuna's Sword Storm can break through the enemy's defense at critical moments, Hashirama's Wood Power can provide treatment and support for everyone, and Tobirama's Ice Attack can effectively control the enemy's actions.

Zulong looked at the performance of the four people fighting against the enemy, and his brows gradually frowned.

He found that they always used ninjutsu intentionally or unintentionally, which made him feel very uneasy.

Zulong knew very well that the Otsutsuki could restrain chakra. If they relied too much on ninjutsu in battle, they would be in a very passive position when facing the Otsutsuki clan.

Zulong decided that he must find a way to make them abandon ninjutsu and learn to use spiritual power to fight the enemy.

He gathered the four people together and said seriously: "You know, you frequently use ninjutsu during special training, which is extremely dangerous. The Otsutsuki clan has a natural ability to restrain chakra, and your ninjutsu will be useless in front of them. We must find a new way to fight, and that is to use spiritual power."

Madara frowned slightly and said, "Spiritual power? We have never systematically learned how to use spiritual power to fight."

Zulong nodded and said, "Yes, this is exactly what we are going to work towards next. Spiritual power is different from chakra, it is purer and more powerful. You must learn to feel the existence of spiritual power and integrate it into your own battles."

Hashirama also asked with some confusion: "Then how do we start learning to use spiritual power?"

Zulong thought for a moment and said, "First of all, you must abandon your dependence on ninjutsu. From now on, you are prohibited from using ninjutsu during training. Force yourself to feel and use spiritual power. I will guide you to gradually master the skills of using spiritual power."

Thus, the four of them began a new challenge. During the training, they tried to restrain their urge to use ninjutsu and try to feel the mysterious spiritual power.

At first, they felt very exhausted. Without the familiar ninjutsu, they seemed to have lost their means of fighting.

But Zulong continued to give them guidance and encouragement.

He asked them to calm down, feel the natural forces around them, and draw spiritual strength from them.

"Spiritual power exists in all things. You must learn to become one with nature in order to better use spiritual power." Zulong said.

As time went by, the four people gradually began to feel the existence of spiritual power.

During a training session, Izunai successfully used his spiritual power to condense a powerful wind blade, which made him very excited.

Zulong felt a little relieved when he saw their progress.

However, he knew this was just the beginning.

They still have a long way to go before they can truly master the use of spiritual power to fight against the Otsutsuki and Shura clans.

In the following days, Zulong continued to increase the intensity of training, allowing them to continuously hone their skills in using spiritual power in various simulated battles.

The four of them worked harder and harder. They knew that only by mastering spiritual combat could they protect themselves and those around them in future battles.

Three months passed quietly, like a fleeting moment, without leaving a trace. When they returned to the ninja world again, the gears of fate began to turn heavily. As soon as they stepped into this familiar land, they saw a terrifying scene - the Otsutsuki clan was attacking.

In the sky, the huge spaceship covered the ninja world like a dark cloud, casting a depressing shadow.

The Otsutsuki clan still stood proudly on the spaceship, overlooking the ninja world below. Their posture was as if gods were examining ants.

The senior elder of the Otsutsuki clan had a look of arrogance and disdain in his eyes. He raised his chin slightly, and his arrogant look made people angry. He shouted provocatively: "The people of the ninja world are just like ants in front of us, the Otsutsuki clan. Today, we will flatten the ninja world and let you see the real power."

His voice echoed in the sky like a huge bell, carrying with it endless majesty and oppression.

"In order to let you experience what despair is, we will not seal your chakra." The senior elder's cold words drifted in the air, as if it was a mockery to the people of the ninja world, "Let us fight to our heart's content."

"Come on, use all your life's knowledge, and we will crack them one by one, so that you will know how stupid it is to be an enemy of the Otsutsuki."

At this moment, there was no fear in the eyes of Madara, Izuna, Hashirama and Tobirama.

Faced with the provocation of the Otsutsuki clan, they resolutely met the enemy.

Madara had a stern look in his eyes and exuded a powerful aura, as if he were an invincible god of war.

Izuna's eyes were determined, his hands tightly grasped with weapons, ready to fight at any time to protect the ninja world.

Hashirama's tall figure is as steady as a mountain, and his eyes are full of responsibility and commitment to the ninja world.

Tobirama had a serious look on his face, his brain working rapidly, thinking of a countermeasure.

The four of them stood there like an indestructible wall, guarding the ninja world behind them.

They have only one belief in their hearts, that is, they will never allow the Otsutsuki clan to trample on the ninja world. They want to use their own strength to bring hope to the ninja world.

Then several people separated, and Madara stood at the forefront of the battlefield, emitting powerful spiritual energy fluctuations from his body.

His tall and straight figure was like an unshakable mountain, and his resolute face was full of determination.

"Hmph, Otsutsuki clan, today is your doom." Madara shouted angrily and waved his hands. The flames of destruction burned fiercely under the stimulation of spiritual power, and the color of the flames changed from the original red to a deep purple flame.

The purple flame seemed to be the devil's fire from hell, carrying with it an endless breath of destruction.

These purple flames seemed to have life, spreading rapidly and forming a huge sea of ​​fire.
