Heaven-defying Upgrade System

The location was the highest floor of the room in the middle of a huge tree trunk. It was the training ground of Dead Wood Group. It was spacious and was surrounded by all kinds of defensive mechanisms. It was a good place to demonstrate the great formation.    

    

Zhu Yan'er excitedly took the crystal that Liu Fei gave him and said, "Later, I will demonstrate the formation. You don't have to be lenient when you attack."    

    

Liu Fei was slightly stunned and then smiled and said, "No need to be lenient? Yan'er, you must be joking!" He was very clear about his own strength. No matter how powerful this grand formation was, after all, only the first layer of the Spiritual Spell could be used. Could it resist his attack? Liu Fei was very uncertain in his heart.    

    

However, Zhu Yan'er firmly nodded her head, her eyes filled with confidence. Her eyes swept the surroundings, and with a move of her palm, the Hundred-Flower Picture scroll was immediately thrown out by her. It instantly turned into a bright colorful light and scattered along with the colorful light. They fell in all directions, and the densely packed landing caused Liu Fei to be slightly startled.    

    

There were more than a hundred landing points in the formation. When the surrounding light lit up, in the center, there was a rainbow-colored light that became brighter and brighter. Zhu Yan'er shouted and pinched the Spiritual Spell in her hand. Her figure moved and she jumped into the array. Then, she closed her eyes slightly. With a wave of her hand, hundreds of green energy crystals flew to the landing point.    

    

The light shone brightly and a loud bang was heard. A colorful light barrier instantly covered Zhu Yan'er. The light barrier looked like a round ball with countless colorful flowers blooming on it. No wonder it was called the Hundred-Flower Picture. Liu Fei's expression changed. He could feel the energy coming from the Hundred-Flower Picture. It was so powerful, and the formation was constantly expanding outwards. The energy was surging.    

    

Pushed by this force, Liu Fei's entire body took a few steps back.    

    

After that, Liu Fei steadied his feet and looked at the grand formation as he muttered, "The power of this grand formation has been fully unleashed. It's actually so powerful." Standing in the middle of the formation, Zhu Yan'er slightly changed the Spiritual Spell. The colorful light turned into a rain of flowers that filled the sky. And... There was a strange fragrance coming. It seemed that the appearance of the rain of flowers had increased the power of the array. As the formation took shape, Liu Fei was surprised. However, judging from the Qi, it was enough to display the power of the grand formation. If he attacked, he really wouldn't be able to get his hands on that place.    

    

Along with the grand formation taking shape, Zhu Yan'er's Spiritual Spell also stopped. Then, she opened her eyes and looked at Liu Fei with a smile. Then she said, "The main function of this Hundred-Flower Picture formation is to defend. However... It doesn't merely have a defensive function. It's just that its defensive function is even more powerful. This rain of flowers is its offensive power. You have to be careful! "    

    

Liu Fei nodded and smiled. Then he closed his eyes. A brilliant light shot out from his mouth. It was the Taiji Cyan Rainbow Sword. The sword energy was very powerful, and it was so bright that it almost made people unable to open their eyes. As Liu Fei's strength became stronger and stronger, the power of the Taiji Cyan Rainbow Sword also became stronger and stronger.    

    

This was something that Liu Fei did not expect. It seemed like the power of the Taiji Cyan Rainbow Sword was like a bottomless pit. As Liu Fei's cultivation base increased, the power of the ___ kept changing. "You have to be careful too!" Liu Fei said. Then, his eyes turned cold, and he became serious. Under the control of his will, the Taiji Cyan Rainbow Sword turned into a ball of light that was as bright as the sun. It carried a chilling sword Qi and rushed towards Zhu Yan'er. In order to discover the changes in the grand formation, Liu Fei was also paying close attention to the grand formation.    

    

The Taiji Cyan Rainbow Sword's speed was very fast, like a shooting star streaking across the sky.    

    

However, Liu Fei did not use his full strength.    

    

"Although this little girl has the protection of the formation, her cultivation base is still there. Naturally, her reaction won't be fast. She won't be able to dodge my attack." Liu Fei thought with a smile on his face. That Taiji Cyan Rainbow Sword! It was already under his control. With a loud bang, it smashed onto the grand formation.    

    

"Bang!"    

    

The grand array immediately trembled intensely as if it had suffered a serious injury. Numerous vortices appeared within the rain of flowers. They seemed to have been affected by the sword qi and appeared extremely chaotic.    

    

However, just as Liu Fei was about to strike again, he suddenly felt that the grand formation that was struck by the Flying Sword had actually condensed into a ray of colorful light. It was like a rainbow, and with a swoosh, it struck towards Liu Fei.    

    

Liu Fei was slightly startled. This grand formation was actually the same as his Gold-Owl Clothes. It had the ability to reflect back. However, the rebounding force wasn't too strong. Liu Fei's heart skipped a beat. If it was used together with the Gold-Owl Clothes, what kind of magical changes would occur? Liu Fei couldn't help but be moved. At least from the attack just now... The defensive ability of this grand formation could be seen. Zhu Yan'er, who was in the grand formation, was completely fine.    

    

Liu Fei moved his body and used the Wind Wave Arts Steps to dodge the rebounding rainbow light. As the Vital Spirit was continuously instilled into the Taiji Cyan Rainbow Sword, the sword intent became more and more piercingly cold. His Qi made people feel as if they had fallen into a cold cave.    

    

This time, Liu Fei was going to use all his strength to unleash the Taiji Cyan Rainbow Sword. He wanted to see how the Taiji Cyan Rainbow Sword would collide with the grand formation again. Just who would be stronger! "Yan'er, be careful!" Liu Fei shouted loudly, and the fighting spirit on his body rose. This Hundred-Flower Picture formation was even more powerful than Liu Fei had imagined, so he wanted to attack with all his strength.    

    

The Taiji Cyan Rainbow Sword instantly turned into a rotating Taijitu, following Liu Fei's control of the Spiritual Spell. The Taijitu Burning Heaven Sword was unleashed. The fiery red light seemed to want to burn the entire space. Even the surrounding restrictions were trembling slightly. Liu Fei controlled the Taichi Burning Heaven Sword and was ready to strike. He wanted to see what kind of response Zhu Yan'er would make.    

    

Zhu Yan'er smiled and said, "I'm fine. Just attack me." Liu Fei nodded his head and understood what she meant. Then, his eyes darkened and the Taiji Burning Heaven Sword whistled out. An enormous force carrying an unparalleled impact rushed violently towards the grand formation.    

    

"Bang!"    

    

A muffled explosion seemed to have shattered the grand formation. Liu Fei immediately circulated the Heaven-defying Strength, and his eyes began glowing with a white light. He stared at the changes in the light. If the grand formation was broken, he would immediately rush in to help Zhu Yan'er.    

    

The grand array was already violently shaking, and Zhu Yan'er's expression in the array was a little ugly. Her hand was holding the Spiritual Spell and it was obvious that she was trying her best to control the grand array to stabilize. At the same time, as she continued to strengthen the defence of the grand array, the consumption of those green energy crystals became faster and faster. In the blink of an eye, more than half of the energy had been consumed.    

    

At this moment, after a violent tremor above the grand formation, a huge vortex appeared in the grand formation. It actually reflected the attack of Liu Fei's Taiji Burning Heavenly Sword.    

    

Liu Fei had only used 60% of his power in order to ensure the safety of the Taichi Burning Sky Sword. But even with 60% of his power, he still couldn't break the Hundred-Flower Picture grand formation. The Hundred-Flower Picture formation was only the first layer of defense. One could imagine how powerful it was. If he cultivated it to the ninth layer, the defensive power would be terrifying.    

    

However, if Liu Fei launched another attack, and the green energy crystal stones in the formation could not be quickly replenished by Zhu Yan'er, it was likely that the formation would be completely destroyed.
