Heaven-defying Upgrade System

1The monster paused for a second and said, "You two actually managed to dodge my attack. Interesting. Alright, I won't play this game with you guys anymore. I'll let you guys see something even more powerful! " As he said that, a powerful aura suddenly erupted from the monster's body. It started to fluctuate in all directions. Liu Fei tried his best to block Mu Lan behind him. Otherwise, he might be affected by it.    

    

After that, the sticky liquid started to attack Liu Fei like a storm. With a flash of white light in his eyes, Liu Fei immediately picked Mu Lan up and dodged in front of the monster. In a short while, he had already pulled away from the monster.    

    

"You two, obediently accept your deaths!" The monster sneered.    

    

Mu Lan said, "We can't run anymore. I really don't want to die under this monster's hands." She could already feel that the monster was getting closer and closer. She looked at Liu Fei, hoping that he could give her a quick death.    

    

Liu Fei stared at the monster and then looked at Mu Lan. Suddenly, his hand moved and a ray of light flashed. Mu Lan smiled slightly. She closed her eyes to welcome the release. A monster's roar suddenly came from afar, "All of you go to hell!"    

    

With a loud boom, the monster's explosive power seemed to have hit an invisible wall. It let out an unbelievable roar. Its power was actually blocked?    

    

Mu Lan opened her eyes and was stunned. What was going on? What else could defend against that monster?    

    

The more she thought about it, the more confused she became. She looked around carefully. Only then did she realize that she and Liu Fei were wrapped in a brilliant formation. This was a defensive Array Picture! Mu Lan's heart slightly moved, although she did not understand this aspect very well. However, he could still see that the attack of the monster had consumed most of the energy of the defensive Array Picture. Fortunately, this defensive Array Picture was relatively strong, so it wasn't broken by him.    

    

Liu Fei gently put Mu Lan down from his arms and said, "Don't worry. This is a Hundred-Flower Picture given by a good friend of mine. Its defensive power is very strong. This monster won't be able to attack us in a short period of time."    

    

Mu Lan nodded numbly. She thought to herself, What kind of good friend is this? How can such a powerful treasure be given away so easily?    

    

"You rest here for a while. I will deal with him!" Liu Fei said. Mu Lan nodded and started to sit on the ground to treat her injuries. Now, the only way to recover was to recover strength.    

    

With a loud bang, Mu Lan opened her eyes wide in shock. Liu Fei said lightly, "You can rest assured and treat your injuries. I have said it before, he will definitely not be able to come in." Mu Lan heard this and nodded her head. Then, she started to focus on healing her injuries.    

    

The monster hit twice in a row, but it did not have any effect at all. She could not help but shout angrily, "Good! Today, I will destroy your grand formation and send you all to hell!" As he spoke, his figure suddenly enlarged, and even his aura rose abruptly. In this way, Liu Fei realized that this fellow should try his best to attack. After that, he replenished the crystal stones in the grand formation, and the energy of the grand formation was maintained.    

    

With a furious roar, the monster's mouth suddenly opened wide, and something seemed to be condensing in its mouth. It emitted a dazzling light. Liu Fei stared at it and thought, "Is this its attack?" He was afraid that he would encounter danger this time, because he could sense it through the Heaven-defying Strength. The huge amount of spiritual energy was constantly gathering towards the monster, and its attack power was absolutely terrifying.    

    

The monster was constantly gathering its strength, like the legendary Yuan Qi Bullets. Once this energy was gathered, it would be difficult to control it, but under the control of the monster, it would be very stable.    

    

Boom! With a dull explosion, the monster suddenly spat out a blinding white light. The surging energy crazily rushed towards Liu Fei. Liu Fei could only see endless light flashing in front of him. It seemed like it was going to drown him. The Hundred-Flower Picture formation in front of him was also shaking. It was as if a gust of wind was going to blow him down.    

    

Bang! The attack finally charged forward, and the moment it made contact... Liu Fei was shaken to the point that his mind trembled. The moment of life and death had arrived. Although the defense of the Hundred-Flower Picture formation was very strong, it was able to withstand the attack of a Heavenly Core Stage ferocious beast. He really didn't know if he could withstand it or not.    

    

Liu Fei could clearly feel a strong pressure coming from all directions. Although the pressure didn't directly affect Liu Fei's body, it kept squeezing the grand formation. Liu Fei couldn't help but let out a sigh of relief. As long as he wasn't in any danger... After that, Liu Fei took out the Green Source Polar Crystal on his body. After that, he continuously replenished the energy of the formation.    

    

So much so that it wouldn't be easily suppressed by that energy.    

    

Just as Liu Fei was crazily repairing the Array Picture, a clear sound suddenly came from the top of the grand formation. It was as if something had cracked open, although the sound wasn't loud. Liu Fei was shocked. This meant that there was a flaw in the Hundred-Flower Picture. Liu Fei immediately suppressed the pressure that kept rushing down and raised his hands. He held back the Array Picture that was about to collapse.    

    

The last loud sound was heard. This was the last bit of energy that the monster had used to attack. The entire space was shaking crazily, and it was filled with dazzling light. Liu Fei couldn't open his eyes anymore, and it seemed like he couldn't feel any pain anymore. A very strong wave of impact was about to break the grand formation. Liu Fei was instantly engulfed by the force.    

    

Such a situation was beyond Liu Fei's control.    

    

In just an instant, the light in front of him suddenly blossomed. After that, it disappeared, and Liu Fei could clearly feel that all the pressure had disappeared. The world in front of him was still the same as before. Beside him was Mu Lan, who was still cultivating. The Hundred-Flower Picture in the sky was full of cracks, just like broken glass. The monster in front of him also seemed to have used up a lot of energy. It was breathing heavily.    

    

With a light bang, Liu Fei was shocked to find that... A small formation core that was supporting the grand formation was broken, and the grand formation began to fall to the side. It was like a house that was about to collapse after the storm. But it had not completely collapsed.    

    

Liu Fei could not help but heave a sigh of relief. He finally made it through. It seemed that other than taking the initiative to receive the attack and suffering some injuries, after that, Liu Fei took out the Green Source Polar Crystal. After repairing the small formation eye, he filled the crystal inside. Immediately after, Liu Fei pinched the Spiritual Spell, allowing the formation to stand up again.    

    

"Looks like this Hundred-Flower Picture can even withstand the attack of a Heavenly Core Stage warrior." Liu Fei thought to himself.    

    

At this moment, the monster looked as if it was tired. It looked at Liu Fei and asked while gasping for breath, "Kid, what did you use to block my attack?"    

    

Liu Fei smiled coldly and said, "It's just an Array Picture that I casually refined. I didn't expect it to be able to block your attack." Liu Fei was not that easy to talk to. This monster almost took his life. It didn't seem like a kind creature. It was destined to die.    

    

The monster was slightly stunned. Then, it laughed and said, "Ahaha! Kid, just brag in front of me. Your Array Picture structure is so detailed. Not to mention you, it's just me. You can't even do anything, did you refine it? What a joke! "
