After everything was ready, Zhao Yichun led the students of the Future Academy to take the Xue Dove to the southeast mountain range.

Boom......

The dove stopped at the bottom of the mountain, and the students had to hike into the mountain range to reach the alien core.

"Be careful, there's a pit here." Junzi An walked at the front and reminded everyone. followed by Yan Wenjun, Dao Wuji, Mo Yaowen, and a girl in the middle, Lin Yi and Zhao Yichun were broken.

Mo Yaowen's own research on the monitoring aircraft can show his skills this time, this aircraft is very knowledgeable, just the flight mode used in the flight is different from the general aircraft device, Mo Yaowen in order to reduce the noise did not use the jet or propeller flight mode, but the use of anti-gravity suspension by changing the position of the aircraft's own center of gravity to achieve flight monitoring.

Through the aircraft to explore the way ahead, everyone also avoided a lot of dangers along the way, and the width of the crack into the crack became narrower and narrower, and the narrowest place could only allow one person to pass through, and there was also a bottomless gap under the feet.

Here, even the future academy students in dark matter engine armor are helpless.

Mo Yaowen's flying machine found something unusual, and Jun Zi'an made a gesture to stop moving forward, because through the gap in front, everyone heard the sound coming from the front. At this moment, everyone raised their hearts to their throats, and there was a voice roaring not far ahead, because everyone knew that this roaring sound was the alien race that besieged Yu Ling's troops not long ago, and their roars were terrifying, and everyone still had a numb scalp when they heard this sound.

Everyone glanced at each other, slowed down their breathing and waited for their roaring sound to disappear, this roaring sound is not groundless, because these alien races live underground all year round, so their vision and sense of smell are relatively weak, but we all know that the speed of sound propagation in solid is the fastest, so their hearing is extremely keen, and the sound of Zhao Yichun and others' movements accidentally reached their ears, and they roared.

However, these alien races are the largest number of alien races in the last siege of Yu Ling's troops, and they are also the weakest of these alien ranks, through the preliminary judgment of Yu Ling and others, these alien races are not only related to nuclear radiation, but also related to some of Yu Ling and others can not be found, and through the news received by Yu Ling, it is judged that there are more than this kind of mutated creatures living in the stratum at present, the closer to the center of the earth, through the increase in magma temperature, there are more terrifying creatures that have been mutated and formed inside.

So this is also the reason why Yu Ling hurriedly withdrew all the reconnaissance teams sent before.

Under Zhao Yichun's instructions, Yan Wenjun used the Void Eye to create something similar to the principle of black hole absorption, absorbing all the sound waves emitted by Zhao Yichun and the alien race into the device.

It didn't take long for the roars of these aliens living on the outskirts of the underground to gradually subside, presumably because the absorption device created by Yan Wenjun absorbed the sound waves.

When the voices of these aliens slowly weakened and disappeared, Zhao Yichun and the others began to move forward again.

Everyone has the experience of being almost detected by the alien race just now, and they have become more cautious, and the next action is also going on smoothly, everyone saw through the gaps all kinds of creatures that have undergone nuclear radiation mutation, and with the increase in temperature, Mo Yaowen and the others have nothing to do because they are wearing dark matter engine armor, but Mo Yaowen's high-tech aircraft has great requirements for temperature, and it is more sensitive to temperature, and at this level of temperature, the aircraft loses its role and has to be put away by Mo Yaowen.

The flying machine was put away, and if everyone lost a help, the road below would be even more difficult.

The further down you go, the higher the temperature rises, and the Dark Matter Engine Warframe also plays its role, and the upgraded Dark Matter Engine Warframe can automatically generate an energy shield under certain circumstances. It can isolate all external energy interference......
