It seems that Dr. Qin is really worth something.


    There are so many space cracks near the ozone layer of blue star. Doesn''t he know? Will he not send someone to investigate?


    Ye Dong hesitated for a moment, then asked Dr. Qin, "Dr. Qin, what''s the matter with those space cracks?"


    Dr. Qin smiled bitterly and said, "do you know what is called plane invasion?"


    Ye Dong looked at the ghost, thought about it, and said, "in fact, I don''t know much about cosmology. Is the plane invasion a person from another world who has entered this world?"


    "The other party is not necessarily human." Dr. Qin took a deep breath and then said, "these cracks first appeared a hundred years ago. At that time, it was also an era with the most rapid development of Bluestar technology. The initial shape of space cracks was not the crack shape you see now. It took more than 100 years to gradually become like this.


    At first, the thickness of the ozone layer was only reduced, and we were also looking for the reasons for the reduction. However, because the available information was too scarce, and Bluestar was in an era of scientific and technological development, I also had a lot of projects on hand that were being studied.


    For the reduction of the ozone layer, we only think that the rapid development of science and technology and the continuous rise of harmful gases until we developed the magnetic levitation technology, and those chemical plants were eliminated by the times.


    Originally thought that in this way, the thinning trend of the ozone layer should be stopped, but unexpectedly, the thinning trend of the ozone layer did not stop, but increased day by day with the passage of time, and cracks began to appear. Originally, it was only about a centimeter in size, but now it has expanded to a few meters, with a maximum distance of more than ten meters. "


    The ghost added at this time, "the formation of space-time tunnel also corrodes a hole surface in the spatial ligament, cuts off the spatial flow layer, and judges the distance between the spatial flow layer and the distance between space and space, as well as time.


    The crack is caused by the decay of the space flow layer and the excavation impact.


    If there is a crack of more than ten meters, it means that the size of the creatures excavating this space is about ten meters. Therefore, the creatures invading the plane are not necessarily human, at least human, and can never grow to that size.


    Moreover, ordinary substances cannot damage the space ligament. There is only one substance that can corrode the space ligament, that is dark matter. "


    Dark matter refers to the ghost itself!


    The ghost took a deep breath and said, "originally, I planned to break the spatial ligament and try to dig to see if I could open a new space-time tunnel.


    However, because it takes too long to go, and there is no life feature to show where I can go in a short time, it is estimated that if I have no brain to dig like this, it will be impossible to really open a space-time tunnel for hundreds of years.


    The space cracks above the blue star are excavated point-to-point and straight line. Otherwise, the cracks will not last so long, but will appear at the moment when they are about to dig through the space-time cracks.


    In other words, the blue star is targeted by other creatures in the plane world.


    And they have used more than 100 years to open up space cracks, and they are about to succeed!


    At that time, I only saw something moving, but I wasn''t sure what it was, but they were really about to get through! "


    The ghost said and looked at Dr. Qin, "when they open the space crack and fix the space-time tunnel, when the ozone layer of the blue star is destroyed, the vast majority of creatures on the blue star can''t resist the direct ultraviolet and heat of the sun, but gradually decay, the mountains, rivers and oceans will wither, and mankind will go extinct again!


    On this basis, don''t forget, there are these creatures who open up the cracks in space.


    If their goal is blue star from the beginning, they will never let go of any creature on blue star.


    This is the drawback of the rapid development of science and technology! "


    Dr. Qin slightly clenched his fist, "if there is civilization in the universe, with the level of civilization we currently have, it may only be the bottom, but even the bottom is enough to attract the attention of other civilizations.


    Because the scope of the crack is too large, I don''t know how to control it. If I don''t say it, it''s just to cause unnecessary panic, but... Considering the time and the corrosion rate of the ozone layer, the blue star will experience a terrible plane invasion in a few months or years. "


    "Perhaps the biggest place is not the creatures, but the sun above our heads." the ghost said faintly, "the blue star has been protected by the ozone layer for a long time, so that the creatures and plants on the blue star can grow freely, but if there is no ozone layer, without the invasion of these creatures, mankind will perish in a few years."


    Ye dong now finally knows why the creator did not come to pick him up.


    The rapid development of science and technology has led to a plane invasion!


    Did the creator intend him to stop all this?


    Can he really stop the plane invasion?


    Ye dong thought for a moment and then said, "that is to say, compared with biological invasion, the greatest threat to mankind is the sun after the ozone layer falls off?"


    Ghost shadow and Dr. Qin nodded firmly.


    Ye Dong asked, "can the cold block ultraviolet rays?"


    As soon as he said this, Dr. Qin was slightly stunned. The ghost seemed to be a little surprised, and the shadow trembled slightly.


    Dr. Qin said, "the ozone layer is actually a layer of trace gases. The cold... May also block the penetration of ultraviolet rays. I once had a similar idea. It is difficult to use my cloud layer to replace the ozone layer, and it is necessary to surround the whole blue star.


    With my ability, I can only resist a small part, and my attention is focused on the creatures in the space crack. "


    Ye Dong nodded and said, "I can try to spread my cold under the ozone layer of the whole blue star, seal the entrance of the space crack, and even inject the cold into the space crack. During this period, Dr. Qin, you should take action."


    Dr. Qin wondered, "you mean building an underground world?"


    Ye Dong nodded and said, "yes, even if it''s only a few months, I think we should try to let all humans enter the underground world until the plane invasion is over. There are a lot of things to do. You should know better than me. When the end of the world comes, start now!"


    Dr. Qin took a deep breath and said, "this will cause panic and panic will bring disaster."
