In the "concave" shape of the building, the floor of the first floor is like a modified and then turned over, with three huge circular openings in the floor side by side, and inside each of them, a fan with a diameter of nearly 30 meters is installed. Pen "Fun" Pavilion www.biquge.info

The three fans, which were once one of the most important components of the gas circulation system in the entire Wind Bride, and the various units under the fan blades, were completely abandoned here by humans who had to build a new gas circulation unit due to the catastrophe a hundred years ago.

However, even though it has not been used for more than 100 years, nearly half of the fans and their units can still be used, and about half of them are still in operation as soon as the power is turned on.

The broken, chipped, and dusty fan blades struggled to operate due to the rust of the bearings when Ping An and the others first arrived in the area. Therefore, when Aoba walked over the "panel of the range hood" with a rope, he was not able to create a fan blade with a strong wind, so it did not affect him. Just now......

Of the three fans arranged from left to right, the leftmost one is not running because the bearings are completely necrotic. And the two doors next to it, during the time they arrived here, slowly turned more and more smoothly, so that now they were able to set off a strong wind.

The fan protection nets scattered like oil filters and all kinds of waste on the "range hood panels", but all the relatively light ones, are blown up by the air flow rolled up by the fan, and they continue to fly upwards rapidly, causing some trouble to Ping'an and others who want to cross the recess of the building.

At the same time, the broken units under the fan also began to discharge outward, releasing crackling electric sparks.

If they didn't want a large explosion and a major fire in the area after it reached the explosion critical state, then they would have to go into the gas circulation machine now, cut off the power supply, and prevent the machinery from continuing to discharge and operate.

"Tsk, it's good that the fan is running normally, so the airflow is upward. If the fan is reversed, forcing the airflow to move downward, and then forming a huge attraction, then I am afraid that when Tang Mo and they use the rope to cross, even if they are not sucked down, and then fall to their deaths on the fan protection net, those objects that fall down immediately will also smash them out. What's more, it is not impossible that the protective net will be broken, and then everything on it will fall into the development of these two huge 'meat grinders'. ”

Not long after the talent Aoba used the rope to descend, with the help of the adsorption belt, together with the two operators belonging to the Wind Bride and Takami, he overcame the upward raging air flow and descended downward, and when the four of them arrived at the "range hood panel", they stopped muttering in their hearts and devoted themselves to the next work.

Following Takami to the top of the blades that didn't move at all, and using the visual device to perform a fluoroscopic scan downward, he quickly estimated the amount of strong acid needed to open the circuit.

"One protective net, three under the net should be fine, right?" As he spoke, he felt four orange-sized, dodecahedron strong acid bullets, and since this was the first time that this weapon from the Human Interstellar Alliance had been used in actual combat, he raised his eyes to Takami in order to ask for his opinion.

"Yes, that's enough. The blasting time can be set according to the law of free fall. Seeing that Tomorrow took out four dodecahedron-shaped projectiles without hesitation, he was glad that he had memorized the different functions of different shapes of projectiles, nodded to Tomorrow with a look of affirmation, and then beckoned the two beside him, and went down to the first floor to help them when they needed help, and stepped back with him.

In order to minimize the influence of the wind as much as possible when the fans in the two holes next to it are running, it is impossible to throw the projectile tomorrow, so a strong acid bomb is properly placed on the fan protection net.

Then, the strong acid bomb that was set by tomorrow's time was blasted according to tomorrow's preset just a few seconds after he stepped back.

The strong acid bomb, which was not filled with gunpowder and therefore could not ignite the combustible, used the strong acid sprayed out to make a large circular hole in the fan protection net, which was slightly deformed by the wind. Then, after stepping forward again, after pressing the detonation button, the remaining three strong acid bombs with the same explosion time set were thrown into the hole in the protective net.

Under the protective net, the three fans that are isolated from each other will not interfere with the airflow of each other, so the first strong acid bomb that falls down quickly and smoothly corrodes an opening in the fan. The other obstacles under the fan blades were also cleaned up by the other two strong acid bombs that exploded with it.

In this way, which is much faster than "cutting one obstacle by one with a cutting laser", he opened a downward path for his group of four tomorrow, and soon took the lead under the fan blades with the protection of strong acid protective clothing. Takami, who followed closely, soon rushed to his work goal after entering the gas circulation machine.

Under the "range hood panel", Takami and Akimitsu, who took out the corresponding tools from their respective backpacks and began to cut off the power and destroy the dangerous parts of the leaking unit, were helped by two operators with guns who could perform precise laser cutting according to their requirements at any time, so they could complete their tasks before an explosion or fire broke out in the area.

At the same time, above the "range hood panel", when Gao Jian and the other four were busy, Shu Lang's three robot assistants, Tang Mo's other two comrades-in-arms of the same ship operator, and Edward also successfully arrived at the passage where Aoba was located with the help of the suspended rope, against the howling of the wind, and under the condition of constantly being hit by various small objects.

"Fortunately, when the wind was not strong just now, I let Dr. Shu be the first to pass, otherwise the air flow is so strong now, is it really a bit big for him to cross under such harsh conditions." Peter, who was whispering in his heart as he was about to fasten the lock to the rope, was not able to leave the corridor immediately, because the inadvertent worm came.
