This laser defense system was conceived by Xiao Hui to resist the high-speed artillery bombardment of the Western enemy by unknown means so far, and next time if there is another rock iron beast cub to attack, there is no need for Bai Xiaofei to risk his life, and the laser cannon can destroy the rock iron beast cub with one shot.

It's just that the laser cannon was put into use for the first time, but it was to deal with the rockfall caused by the earthquake, but fortunately, this defense system is there, and the rockfall has not caused large-scale casualties except for smashing some weak monsters and buildings.

Xiao Hui was sending the injured citizen to the Genetic Temple for treatment, when he suddenly heard a voice from the dome: "All the rock giants obey the order, immediately close all the entrances and exits!" Iron Tree Beast, Vine Monster, and Crystal Two-Headed Worm immediately cast their abilities to help the Rock Giant fortify the entrance! ”

That was Bai Xiaofei's voice!

Xiaohui flapped her wings and flew into the air: "Bai Xiaofei, what's wrong?" How do you close all the entrances? Is there an enemy invasion? ”

Bai Xiaofei clenched his fists: "No, it's not the enemy invasion, it's the catastrophe caused by the Shuangri volley!" I just saw outside the dungeon that this double sun is over our eastern continent, the orbit of the alien world is very close, the high temperature has burned all the crops, the huge gravitational force has caused a lot of volcanoes to emerge from the lonely peak, and at the same time, the heavy snow on the lonely peak has also melted, and a great flood of the world is rushing towards the valley! ”

Xiao Hui was stunned, the dungeon is located under the valley, and the flood on the lonely peak will wash down, which will turn the valley into a giant lake, and the dungeon will become an underwater city, no wonder Bai Xiaofei urgently ordered to close and strengthen the entrances and exits, otherwise, even the entire dungeon will be submerged.

Xiao Hui hurriedly said: "But as soon as the dungeon is closed, we won't be able to escape—can't we mobilize everyone to evacuate the dungeon immediately?" ”

Bai Xiaofei shook his head: "No, the high temperature and energy turbulence brought by the Double Sun Volley are too terrifying, and the vast majority of the people will die as soon as they get out of the dungeon." The flood actually protects us, if there is a huge lake above the dungeon to isolate the heat and energy turbulence, it is equivalent to a protective layer, we are safe below, but we have to do a good job of sealing and isolation. ”

The flood came very quickly, and the snow and glaciers that had not melted for tens of millions of years on the Lone Peak melted into water almost in the blink of an eye under the double sun volley, and even the high temperature of the flood rushed down from the 10,000-meter-high Lone Peak Mountain Range towards the valley.

Boom, the sound of a flood rushing like thunder, rolled over the dungeon, all the Xia tribesmen and monsters stared at the dome above their heads, their faces changed color, and the dome several kilometers thick was trembling like a piece of tissue paper under the impact of the flood, and countless rubble fell again.

Suddenly, a flood broke through the closed entrance of the rock giant, spraying into the dungeon like a pillar, the snake immediately pounced, spewing out a cold air, freezing the flood directly, and the iron tree beast, vine monster, and crystal two-headed insect that had been on standby next to him immediately stepped forward to strengthen the gap, and the crystal two-headed insect directly crystallized the rock giant and the rock next to it, and there was no gap.

Similar gaps appeared everywhere, after all, it was impossible for the rock giant to block the entrances and exits tightly, and floods of different sizes poured into the dungeon, but fortunately, Bai Xiaofei commanded properly, and the gaps were blocked one by one.

Outside the dungeon, the catastrophic flood still rushed forward until it rushed into the acid sea, this endless stream of ice and snow fresh water, greatly diluted the acid sea, so that the acid sea is no longer a forbidden area for life, a large number of creatures can survive in the sea - naturally, this is a later story - when the double sun left, the huge flood level subsided, a new giant lake was added to the eastern continent, and the lake was the original valley.

The Eastern Continent has become unrecognizable, countless giant volcanoes have appeared in the Lone Peak Mountain Range, spewing toxic smoke and high-temperature magma all the time, even the flying monsters are difficult to get through, completely cutting off the connection between the East and West continents, the snow water on the Lone Peak flows endlessly to the valley lake, and then to the acid sea, and a large number of new monsters have evolved in the acid sea, they climb the iron wall, and live freely in the valley lake.

This scene of changes in the mountains and seas takes tens of millions of years on the earth, but in another world, it is just a few sunrises and sunsets.

In the underground city, the Chinese people are rebuilding their homes, the rubble on the dome is no longer falling, the injured Chinese people have also returned from their injuries after being treated by the genetic temple, and many smashed factories and communities are in full swing to rebuild.

In the past, outside the dungeon, even if a large number of clansmen died, they could lick their wounds and continue to survive, not to mention that under Bai Xiaofei's timely response, Huaxia did not die in this catastrophe.

Xiao Hui sent away the last healed wounded person in the Gene Temple, and said to Bai Xiaofei with a wry smile: "I used my soul energy to sense the outside of the dungeon, the dungeon has been completely sealed, and there is a huge lake outside, and no one can leave the dungeon. ”

Bai Xiaofei said: "It's okay, the dungeon is big enough, and it has its own ecosystem, we don't need to worry about being suffocated and starved to death." In fact, we can't get out, and the enemy can't get in either, so we can take advantage of this rare opportunity for peace to carry out the art of transforming people. Not to mention anything else, after turning into a human, the monsters need to eat much less food, so as not to bring too much pressure on the dungeon's food demand. ”

Xiao Hui said: "But, could it be that millions of our Chinese citizens will be locked in this underground city forever?" ”

Bai Xiaofei said: "Closed forever? No, as long as we continue to evolve and improve our strength, the rock dome of this dungeon and the lake above it will not be able to seal us off. ”

Xiao Hui breathed a sigh of relief, indeed, Bai Xiaofei was right, others didn't say it, it was the two of them and the snake, etc., if they really wanted to come up with a dungeon, there was a way, even Lena who had just turned into a human form-

Xiao Hui exclaimed: "Lena! Lena is still outside the dungeon! ”

Lena, because of ancient traditions and oaths, stood alone on the lonely peak, and when the double sun was in the sky and the dungeon disaster struck, he was never heard from again.

Bai Xiaofei sighed in his heart, he had already thought of Lena, but the dungeon had been closed, and it was impossible to forcibly go out for Lena and put millions of people in danger.

Bai Xiaofei comforted: "Xiaohui, don't worry, Lena is not an ordinary child, his kung fu has been small, and he will definitely survive safely." ”
