Gao Song and Yan Qingyu in the distance seemed to see Si Chen killing and injuring the Earth Spine Dragon Beast, Gao Song glanced at Yan Qingyu in the distance, nodded suddenly, and then took the black magic bow again, but shot out a fireball spiritual energy arrow.

This psionic arrow is an introverted psionic bomb, there is no vitality overflowing, just like a red lightning, slammed into the neck of the earth spine dragon beast, although it did not hit the wound, but boom, this fireball bomb, instantly exploded out of a flame mushroom cloud of more than 100 meters, enveloping the earth spine dragon beast in it, and then, the earth spine dragon beast was in the explosion, was overturned several times, and was almost blown out of the big pit. However, blood splattered out.

Boulder Valley, which was originally a large crater, was blown up by a fireball bomb and sank deep again.

The Earth Spine Dragon Beast was blown up and rolled, and blood flowed out of its neck again, and it was so painful that he roared and roared, and it actually jumped out of a large pit hundreds of meters with a bang, and the boulder valley seemed to be shaking.

The Earth Spine Dragon Beast roared at everyone in the sky, Gao Song and Yan Qingyu seemed to know their mission, and immediately landed from the air, but they still avoided it, and shot an ice bomb again, hundreds of meters of the boulder valley were frozen, and the Earth Spine Dragon Beast was also frozen inside, but the yellow light of the earth was filled, and it was suddenly shattered into ice.

The hot and cold bombardment made the Earth Spine Dragon Beast seem to be injured a lot, and roared in the direction of Gao Song and Yan Qingyu, because of the distance, the yellow light filled the stone shot out, although it could attack them, it could not cause substantial damage.

And Shen Zhou and Hai Fengxue saw it, and even shot B-level spiritual energy bullets, although they could not cause damage to the fierce beasts at the peak of the spirit level, but the fireball explosion and the ice blade storm cross-bombardment, still angered the earth ridge dragon beasts, and frantically pounced on them.

Si Chen saw that the Earth Spine Dragon Beast had finally been lured out of Boulder Valley, and was busy looking for caves or other places that might enter the Sealed Land? Suddenly, he saw that a huge stone cave appeared in the place where the tail of the earth ridge dragon beast poked out, as if the dragon's tail was stuffed in the cave in the mountain, not hidden in the rocks, if it wasn't for Takamatsu's storm bomb to blow up the bones of this mess of corpses into a big hole, it would not be easy to find this big cave where the dragon's tail was hidden.

Si Chen hurriedly called Yu Ying and the three of them from the edge of the boulder valley, and then pointed to the mountain-style cave hidden in the rocks, saying that this big cave might be the road to the sealed land.

Ye Wolf and Mu Qing seemed to be a little confused, but Yu Ying's divine sense was keen, and he immediately noticed some of the aura overflowing from this cave, which indeed proved that Si Chen might be right, so he didn't have any insistence, nodded at Mu Qing, and flew into the big mountain cave. Although Mu Qing didn't understand, she still believed in Yu Ying and flew in, as for the leaf wolf in a dilemma, in the end, she still stubbornly followed up.

Gao Song and the others used the spirit bomb to blow up the earth ridge dragon beast and lure it to the far side of the boulder valley, Si Chen soon found this mountain-style cave, Yu Ying also smelled a trace of alien breath wafting out of the cave, which was not much different from the pollution yuan in the depths of the black water pool, and knew that the energy stone in the sealed place of the boulder valley was only afraid that it was also polluted, no wonder Si Chen wanted to assign him to this team, completely to devour those pollution elements.

Despite this, Yu Ying did not postpone it, took the lead and flew into the big cave, which was full of scratches from bone spurs, frowned slightly, and turned around to see Mu Qing and Ye Wolf also flying in, and hurriedly said hello, and the three of them entered the big cave next to each other, fortunately, there was only one passage to enter the big cave.

Yu Ying didn't feel the aura of danger in front of him, and flew almost at an extremely fast speed, rushing into the depths of the cave. Mu Qing and Ye Wolf didn't dare to delay, the horror of the Earth Spine Dragon Beast was vivid, Gao Song and the others might be able to lure and contain the Earth Spine Dragon Beast, but if they wanted to kill it, even Si Chen couldn't do anything about him, unless they used a hell-level bomb, as if time was pressing, they had to activate the power stone of this sealed place as soon as possible, otherwise, the return of the Earth Spine Dragon Beast would definitely be a dead end for them.

The three of them quickly broke into the depths of the cave, which was already pitch black, but they all turned on their headlights, and the cave was large enough for them to spread their wings and fly.

After flying into the interior of the mountain for less than two minutes, and then turning a few hundred meters below, two forks in the road appeared in front of them, which made it quite difficult for them.

Time was tight, and they simply didn't have the time to find their way.

In the two passages, Yu Ying's divine sense sensed a faint pollution element, and some of them were uncertain. Jianmu Xiaoshu, who has a strong perception of the polluting element, is busy driving Jianmu Xiaoshu, and it is really perceived by it, and a branch points from his finger to the left passage.

Yu Ying hurriedly said, and ran out here.

Ye Wolf looked at him with a frown, expressing doubt. But Mu Qing didn't doubt Yu Ying's decision, and also stepped on the ground passage and followed. Ye Wolf had no choice but to follow.

The height and width of this passage are much smaller, so the three of them ran like the wind towards the depths of the passage, and did not slow down, but in this winding passage, they ran for five or six minutes, at least a thousand meters deep into the mountain, maybe the problem of bending, not so deep, but enough to make people marvel at the depth of this passage.

Yu Ying, who was running in front, soon found that there was a trace of artificial excavation around the passage, so he had to be vigilant and slow down, Mu Qing and Ye Wolf were also cautious, and then, they saw some stone statues on both sides of the passage, like a warrior standing proudly on both sides of the passage, holding a sword in his hand, stuck in the ground, looking at both sides of the passage with a solemn expression, feeling that these stone warriors seemed to be guarding something?

Yu Ying saw that these stone statues were all human, so he secretly screamed that it was not good, there were artificially excavated stone statues in the mountain this day, it seems that the project of sealing the enemy of the alien race is only afraid that it is unimaginably huge, but fortunately, the smell of pollution has not increased to a great extent, this is definitely not the boundary of the alien seal, this may be an engineering area.

Even so, Yu Ying carefully avoided these stone warriors, and walked cautiously, less than two hundred meters, he saw more than a dozen stone warriors, as if entering the underground palace of the abyss, which made him vigilant, but fortunately, he did not find any fierce objects, it is estimated that this is the territory of the earth spine dragon beast, the regional awareness is very strong, and no fierce beast dares to approach.

Soon, everyone carefully passed through the stone statue passage and came to a large stone gate.

This big stone gate is fused with the rock mass, if it is not for the artificial traces on the stone door and some gaps on the side of the door, it is really impossible to see that this is a stone gate.
