However, then everyone also discovered a problem, because the elevator shaft is filled with rubble, so in fact the underground is a confined environment, which means that the oxygen will eventually run out.

Although the exoskeleton armor in their hands has the function of oxygen circulation, the thirty-one exoskeleton armor cannot support the huge team of nearly 5,000 people anyway, and the oxygen here will quickly run out.

"We're not going to suffocate here, are we?" Uncle Mizuda asked, lying in front of the stone pile in front of the hall in the underground area, knowing that not only was the elevator shaft buried, but also that the ground was covered with broken rocks that had fallen when the cave collapsed.

Originally, John wanted to light a cigar, but noticed their current situation, five thousand people were trapped in a confined environment, and if he smoked, it would affect others, so John put away his cigar and walked to the center of the underground hall to look up at the ceiling, and then smiled slightly.

Jack knew what John was laughing at, they hadn't lost yet, they still had W and Xiaotian, as long as they could rush back, they could rush out of the ground to join W, and then fight to the death with those star stripe holders, but the most urgent problem at the moment was oxygen.

The space in the underground area is very limited, only 3,000 square meters, if you count the cube of air, there are only about 8,000 cubic meters of air, which can be used to support the breathing of nearly 5,000 people, then it can only support more than two hours.

And W has been walking for more than two hours and is probably on their way back, and they need to hold on until W comes back.

And Kylo seemed to have figured it out, he didn't rush to let the starstripe holders dig the ground, he knew that the oxygen in the ground would definitely not be enough, and if they didn't take the initiative to break through the ground, they would be suffocated to death, he just ordered these starstripe holders to stay put, he just had to wait.

Before you know it, it's getting dark, the winter evenings come early, and after the sun sinks to the horizon, the night begins to cover the ruins, and the ruins are covered with gravel, which a few hours ago was a mountain, but now it is the ruins after the mountain collapsed.

And W and Xiaotian finally rushed back, far away, W saw the ruins in front of her through the over-the-horizon observation function, and she didn't rush to get close to here.

"We seem to be back late, it's all gone." Through over-the-horizon observation, W observes the ruins on the ground, the entire mountain has collapsed into rock fragments, and the secret military base has become a large rubble ruin.

W was a little lost, if she didn't choose to come out, but stayed in the base, would it be better, it was her absence that caused such a tragedy, W sighed softly, is it all over? What should she do in the future, how should she fight against Kylo.

Because the Resistance Army is located 60 meters underground, and the collapse of the mountain has also destroyed the radio transceiver device in the base, so in fact, the Resistance Army located underground is in a state of disconnection, after all, the radio signal cannot directly pass through the 60-meter-thick underground rock layer and then fly to the satellite, and then be received by W, this kind of technology does not exist in the world.

W was suspended in mid-air, some tears in her eyes turned to Xiao Tian, she didn't know what to do in the future, she was very lost now, even though she was now wearing her top-of-the-line exoskeleton armor, she still didn't know what the hope for the future was, an important hole card in her hand to defeat Kylo was gone, and her group of companions were gone.

However, Xiao Tian still observed the ruins far, far away through the over-the-horizon observation function, and he found some points of light, he knew what they were, it was the silvery-white ion flow generated by the ion thruster of the starstripe holder, and if it was the starstripe holder, what were they doing there.

Xiao Tian stared at the point of light, he always felt that something was wrong, the large army of the resistance army did not look like it had been annihilated, there was only gravel, there was no trace of battle, and there were many points of light, all the time around the ruins, and the point of light was just floating still, not moving, it looked suspicious.

After thinking for a while, Xiao Tian finally knew what was going on, and then pulled W to fly forward, but W immediately used a reverse thrust to offset the output generated by Xiao Tian's exoskeleton armor, and W looked at Xiao Tian with a questioning expression.

"They didn't die, they seem to be buried in the ground, if they were annihilated, these starstripe holders would have already left, looking at this mountain collapsing like this, I suspect that the resistance side of the communication device was also destroyed, so we can't receive follow-up information." Xiao Tian explained.

Hearing what Xiao Tian said, W also began to think, and she also suddenly realized that the resistance army was not annihilated now, they were now underground, but she immediately came to think of oxygen, from the collapsed ruins, the oxygen cycle function in the base has also failed, if they are underground, then there will be a lack of oxygen, so why didn't they break through the ground and fight a decisive battle with the star stripe holder.

Thinking about it along the train of thought, her eyes suddenly widened, she understood, she understood all this, they were waiting for her, W was the main force in the battlefield, they were waiting for W's return, with the existence of W, there would be a glimmer of life in the decisive battle with the star pattern holder.
