"Everyone pay attention to the rocks down there to avoid jumping down and spraining their feet." When Xiao Yi said this, he held Lu Xuexin who came down from above.

"You don't need to help, I'll fly down." Xiao Yi smiled when he heard this, and at this moment, the others had all come down from the high platform.

"Boss, look at how the bottom of this high platform is empty." When Xiao Yi heard this, he immediately cast his gaze.

Ding Hao's words also attracted the attention of others.

Xiao Yi found that the bottom of the high platform they came down was really empty as Ding Hao said, and it was 30 centimeters above the ground, and it was pitch black below, and it was almost impossible to see the bottom.

At this moment, Lu Xuexin walked over.

"Xiao Yi, did you say that this is the research institute?"

"According to the distance, it should be very close, or you can use your mental power to take a look."

"I've already sensed it with my psychic power, it's very deep down here, and I can't feel it at all, but I look at the traces around me, and this place is likely to be an underground river before."

"Xuexin, can you project the picture below?" Hear Xiao Yi's words.

Lu Xuexin nodded affirmatively: "But it's too dark below, even if it's projected, you can't see anything." ”

Hearing this, Xiao Yi smiled, and the next moment, Xiao Yi had already condensed a new lightning ball and threw it directly.

At this moment, a spiritual projection had appeared in front of Lu Xuexin, and the picture above showed the scene below illuminated by the lightning ball.

If someone looks closely, they will find that inside that gap, there is a huge psychedelic eye floating there at this moment, which is exactly the skill released by Lu Xuexin.

Sure enough, as Lu Xuexin said, there is really an underground river down here, but this underground river is almost more than 1,000 meters high from where they are, and at this moment this underground river is close to drying up, with the drop of the lightning ball, Xiao Yi can already clearly capture the rocks at the bottom of the river.

At this moment, Tang Yunfeng seemed to hear something.

"Xiao Yi seems to have some voice." When they heard this, all the people became alarmed.

Xiao Yi also immediately looked in the direction of Tang Yunfeng's finger, which was directly in front of them coming down to the high platform.

"Let's go over and see." Obviously, Xiao Yi is extremely confident in his current self.

Xiao Yi found that there was actually an underground river in front of him, and he could already hear the clear sound of the underground river running water as he walked, but when everyone walked nearby, they found some traces of man-made in this vicinity, there was actually a house here, but this house was just a very simple building, and when everyone was about to step forward, Lu Xuexin stopped everyone.

"There's something strange about this house, and the mental power can't detect it at all."

Hearing Lu Xuexin's prompt, Xiao Yi hurriedly took a closer look, this is a house built in the cracks of a boulder, obviously this is built to support this boulder, but Xiao Yi is very curious, who would build such a building here.

When everyone stepped forward, Xiao Yi found that there was actually a heavy steel giant gate here, and at this moment, this huge door had obviously been opened, and it was opened from the inside, and there were obvious traces of rust on the ground.

Xiao Yi suddenly remembered that monster, and that monster had come out from here.

Just when Xiao Yi was a little confused, a sound suddenly came from inside the house, it was a knocking sound, as if something was hitting the iron door.

However, with the help of the lightning element, Xiao Yi also heard some more subtle sounds, which were the sound of iron chains rubbing against steel.

At the moment, everyone was silent, and no one spoke.

Xiao Yi pointed to the back, everyone moved back, about 100 meters away, Xiao Yi fixed the electric ball in the air,

Xiao Yi's gaze looked at Lu Xuexin.

Lu Xuexin immediately shook her head: "Spiritual power can't penetrate that iron gate."

"Tang Yunfeng, you create a space door to the levitating logistics vehicle, and if there is anything wrong, take everyone to withdraw immediately." 、

"Boss, what are you going to do?"

"I'm going to go and see what monsters are out there."

"Xiao Yi don't want this, let's just spare it, our task hasn't been completed yet."

"Xuexin, I know, but didn't you look closely? Isn't that the right direction to the underground research institute? ”

"Prepare to retreat first, and I'll go into that room and have a look."

The next moment, Xiao Yi had already created another lightning ball and walked in the direction of the house.

Just as Lu Xuexin was about to catch up, Xiao Yi had already turned into lightning, and he disappeared with a flash.

"This ......"

"Did the captain abandon us?"

"Dead Xiao Yi! How can you do this to me! ”

And Xiao Yi had already appeared in the room after a flash, Xiao Yi found that there was actually an elevator in this room, but the elevator had been obviously damaged and had lost the power supply.

In the direction of the sound, at the back of the house, Xiao Yi walked over slowly.

The next moment, Xiao Yi had already come to an iron gate, and at this moment, this iron gate had been deformed by the hammer, but the heavy steel plate did not completely collapse this steel cage.

At this moment, the sound of iron chains rubbing against the metal floor sounded again, and with a loud "bang", the iron door was actually smashed again.

Xiao Yi looked at the deformed iron gate, and directly cast his elementalization, and the huge lightning element also began to gather. As Xiao Yi's hand touched the iron gate, a heart-rending roar suddenly came from inside the iron gate.

Hearing this, Xiao Yi walked in directly through the iron gate.

What appeared in front of Xiao Yi's eyes was actually a huge stone cave, but the surroundings of this stone cave were full of huge bodies, and even some had turned into dry bones.

And the one who hit the iron door was a huge figure, a giant of about four meters, and at this moment, there was a huge iron ball in his hand, wrapped around his hand.

At this moment, he has been smoked by Xiao Yi's lightning and electricity, but he is not dead, but is still rolling on the ground.

These giants don't seem to have a high IQ, and they look very violent, Xiao Yi found that one of them is actually a super big giant, and his eyes are calmly watching Xiao Yi at this moment.

And Xiao Yi's electric light was also blocked by a white film of light, which obviously did not cause substantial harm to this huge giant.

The next moment, Xiao Yi withdrew his lightning. I looked at this giant.

"Are you wise?" Xiao Yi asked suspiciously, but the giant didn't seem to hear.

Seeing this, Xiao Yi's gaze looked at the white film of light.
