Yoll could see the ancient cracks on the rock wall and the symbols left on it, but unfortunately, other equipment except birds would fail here. Otherwise, if he really wanted to save it, he might come in handy one day.

But it doesn't matter. After all... he will soon see the Dragon Legion left by the Dragon Clan, and there must be more mysterious secrets waiting for him.

As she gradually entered the deep layer of the pit, the light around her became darker and darker. Only the ray of flame in Yoer's hand was still emitting light. Because the bird removed the module of emotions and thinking, it was said that she had no vision. After Yoer gave the order, she emitted a soft light to illuminate the surroundings.

The bird did not hit too many weapon components, and only had a relic energy-gathering cannon as a killer weapon. Because she could completely imitate the state of humans using light thoughts, she could have strong combat power without hardware support, so her body looked so slender.

Through the light, Yoer saw the environment below the pit. There was a huge passage here. At the end of the passage was a huge rock. There was also a pattern carved on the rock, which looked similar to the patterns on the walls I saw before, but this one was magnified many times.

The bird hugged Yoer and slid down gently and landed smoothly on the ground. The huge rock stood in front of the two of them. Just by looking at this, you could feel a sense of oppression coming to your face. When you walked to the huge rock that sealed the door, Yoer slightly twisted the switch on the container, and the glassware opened to the surroundings, like a blooming glass flower, and the flame in the stamen was also released.

Of course, even if the container is opened, the magnetic field that really bound the flame has not been lifted yet, Yoer controlled the flame to touch the boulder. The moment he came into contact, the pattern on the boulder suddenly lit up a fiery red light, and then, like just now, a roaring roar came from behind the boulder, and the boulder was also vibrating quickly, cracking from the middle like a big door, slowly opening to both sides, flashing dazzling red light in the gap, Yoer couldn't see clearly what was inside.

"Preparing for war." Yoer whispered, and the girl behind him raised her hands, put on her posture, and stared at the front.

"Roar!" A harsh beast roar came, and before the door could be fully opened, a few shadows rushed out of it.

Sure enough, Yoll's guess was correct. Before, Geen encountered many guards when he entered the Wind Sky. As for the Fire Sky in Nightwing City, the guards inside were also removed by blood people many years ago. There must be many in this Earth Sky.

Those shadows were extremely fast, and Yoer stood firmly and did not panic. Although with his physique, he would probably be knocked over by these things, he was still very confident. After all, he still had birds and his most perfect combat machine.

The shadows suddenly paused when they were about ten steps away from Yoer. The bird waved its hands and fired them one after another. A series of light bullets were stimulated from her fingertips, accurately hitting each nearby black shadow and directly repelling them. At this time, Yoer saw clearly what those things looked like, which were a group of stone beasts made of rocks.

However, unlike the summoning objects pinched with the earth puppet technique, these stone beasts emitted a slight fire, spreading all over their bodies like blood vessels, and a heat was also emitted from their bodies. As soon as they appeared, the temperature around them had risen several degrees. It was not blood vessels, but lava, and the scorching magma flowed in their bodies like blood.

"Can it be solved?" Yoll asked the girl.

"The risk factor evaluation has been completed, the difficulty is level 2, the success rate is 85%, the failure retreat rate is 97%, and the battle loss rate is 0.5%.

"It's still expected to solve them."

"Receive the order!" the girl replied coldly. As soon as she finished speaking, she rushed out, and more than a dozen stone beasts immediately surrounded her.

The guardian stone beast opened its mouth and sprayed out high-temperature shells. They cooperated with each other to cover the ballistics to form a net of encirclement. The birds moved and avoided them sensitively. Her movements were quick and quick. After dodging several times, they completely analyzed the attack mode of the stone beast and then began to launch a counterattack!

After breaking through the stone beast's encirclement net, the bird slid against the ground to a stone beast, condensed the air in his hand into a blade, and cut it into two pieces from the abdomen with one blow. The stone beast cut into two pieces quickly regenerated from the fracture. The rocks and gravel on the ground were sucked up by a force, automatically filling the wound of the stone beast, and soon one turned into two.

At this time, several stone beasts also detoured behind and began to attack Yoer. Yoer was still standing there calmly. Just as the stone beast's claws were about to touch him, the bird returned to defend in time, raised his hand and waved his hand to emit several sharp air blades to repel the stone beast, ensuring Yoer's safety, and the battle situation was very fierce for a while.

Bird has a combat quick response module specially made by Yoel, which records the combat skills of hundreds of top light nerds, all obtained through investigation, collection and assassination. That is to say, she can use the abilities of hundreds of light nerds, which is extremely omnipotent. However, these guardian stone beasts are not vegetarians. After all, they were refined using the ancient secret technique of the dragon. Even if they are not smart, they are absolutely powerful, especially in terms of quantity.

If it were normal, Yoer would choose to use a larger number of bee swarm tactics to crush the opponent. After all, there are too many combat puppets in his hand, but now there is no way to move in this place except birds.

"Invalid attack was detected and the combat mode was changed." The bird said softly, and the wind blade surrounding his hand also turned into a rising cold air. He waved his hand to slap the side of a stone beast. A icicle quickly condensed, trapping it in it.

The other three stone beasts took advantage of the birds and the frozen stone beast to attack Yoer. However, before they could get close to the cold, they quickly attacked. Three frost marks on the ground spread rapidly, spreading like three white carpets, automatically chasing the stone beast like life. After a while, the three stone beasts turned into ice sculptures and then cracked and shattered.

"Okay, let's not play anymore, lift the first level restriction." Yoll said.

As soon as the words finished, the collar on the bird's neck sounded softly, and the three indicator lights on it went out, and the momentum on her body suddenly increased several times. A gust of wind blew away from the soles of her feet, forming a violent cyclone. Behind her, a pair of wings formed by light thoughts condensed, and each feather was emitting a bright white light.

The stone beasts around them raised their heads and roared angrily as if they felt some threat, and then rushed towards Yoer like crazy. The birds raised their hands with their hands. A wave of domineering thought wave spread out with her as the center of the circle. All the stone beasts were instantly fixed, as if they were suppressed by some unresistible force. Then bursts of smoke appeared from the stone beasts, and then countless fine powder burst out of their bodies, and their huge bodies were pressed into solid small stone balls.

It is hard to imagine how powerful this is. When the Hanging City collapsed, the bird forced it to hold it with its powerful thought wave after lifting the restrictions. Yoll added several layers of restrictions to her after that to prevent it from getting out of control again, but now it is just lifting the first layer of restrictions.

The bird shook the dust stained on its arms and returned to normal again. The attack just now obviously completely broke through the regeneration limit of the stone beasts, making them permanently turn into stones.

However, it was not over yet. There was a larger stone beast in the gate, which was probably more than ten times that of those stone beasts before. After seeing that other stone beasts were defeated, it woke up from its resurrection, and its nostrils touched its nose and spit out a boiling steam breath. It looked like a moving hill, exuding a strong ferocious aura, and its body was covered with tough stone armor, which was quite terrifying.

"Relieve the second level restrictions and lift the weapon restrictions." Yoll didn't want to waste more time here, so he directly let the birds turn on a stronger combat mode.

As the second light on the collar went out, the girl's eyes became sharp. She stretched out her hand to aim at the giant guardian beast inside the door. The simulated skin on her hand quickly cracked, revealing the weapon device installed on her hand. A strange-shaped cannon barrel stretched out from it. At the same time, the energy source in her body was running with all its strength, and red lines appeared on her body, as if they were tattoos. It was the thought-guiding circuit in her body, which emitted a strong light due to the high-strength power operation, illuminating half of her face.

When the weapon was activated, there was no earth-shaking sound, or even no sound, there was only a faint and light sound, and there was no strong light or explosion. It was just a puff, and a projectile with extremely strong penetration force flew out and hit the giant beast.

I didn't see any obvious wounds on the giant beast, but the blood vessel-like networks on my body dimmed, and I fell to the ground without even wailing, as if my soul was suddenly harvested by the god of death.

"Threat has been cleared."

"Very good, restore the restriction mode." Yoel nodded with satisfaction. This was also the first actual test for Bird, and he was still very satisfied with the effect.

"Yes, master." The bird lowered his head and said respectfully, then restored his hands to their original state, and the momentum on his body slowly dissipated and returned to his previous appearance.
