Lu Qianzhen sat on the edge of the adjustment cabinet, her eyes closed, ignorant and unconscious. As a member of the cross-border law enforcement team, she often fights head-on with the demons who are connected to the prosthesis, and the use of avatars is commonplace, and it also allows her to practice the stunt of maintaining a little balance after possessing the avatar.

She attached herself to Ye's body, and made several drastic tactical evasion actions without any sluggishness, but after stopping, her chest continued to rise and fall, and her voice was a little incoherent: "What's the matter with you robot, even if you can breathe, you still feel tired...... Is this necessary? ”

Hong Ye touched his chin and thought about it seriously, he didn't know the essentials, and then read the state of Ye with the sympathetic module, and realized: "Ye's chest cavity is equipped with a platinum-iridium catalytic ethanol air fuel cell as a supplementary power, and it really needs to breathe." There are several power source modules in the adjustment cabinet that can be switched, and the default installation is a hybrid of supercapacitor and fuel cell. ”

He then suddenly thought: "Hey Lu Qian, you said that the evil ghost has not shown up for a long time, could it be that it is also equipped with a fuel cell, not a supercapacitor as you speculated?" ”

Hearing this, Ye's movements stiffened slightly, and when it resumed its action, Lu Qian's true body also opened its eyes and slowly stood up, and replied: "It shouldn't be possible, the experts of the technical group must have considered this issue." ”

A fuel cell is a device that releases the chemical energy stored in the fuel to provide electricity by catalyzing a redox reaction. In theory, the heat released by the complete combustion of one kilogram of anhydrous ethanol is equivalent to 8 kilowatt-hours of electricity, and in practical application, the battery equipped by Ruye can directly add vodka with an alcohol degree of about 60 as fuel, plus the weight of the battery itself and the loss of incomplete conversion, on average, each kilogram of vodka can provide 3 kilowatt-hours of electricity.

This energy density is actually much greater than the energy density of supercapacitors that is less than one kilowatt-hour per kilogram of electricity, but supercapacitors can recover the potential energy in artificial muscles, and they can reach an energy density equivalent to 3.5 kilowatt-hours per kilogram of electricity in the body's motion. If you don't add pure enough ethanol as fuel, the fuel cell of Ye will not look as dense as the supercapacitor.

But that's not the case at all. The density of supercapacitor materials such as graphene is inherently small, and the effective mass of supercapacitors of the same volume is less than half of ethanol.

One is that the proton exchange membrane used by the fuel cell for the reaction is relatively fixed according to the weight and volume of the output power, and the more fuel it carries, the greater the effective mass ratio. Buy a car full of engines, and even the place to put the fuel tank is gone, how can you run.

The second is the issue of fuel addition. The largest energy density in the fuel cell is the metallic hydrogen fuel cell, but this can be completely ruled out, with the current technology can use the metallic hydrogen reactor and constant pressure vessel at least one cubic meter in size. In addition, other fuels that are gases at atmospheric pressure are not easy to carry, and like active wave metal fuels, they are not easy to replenish at any time.

The fuel runs out quickly, and you can't find a place to refill it, so you just have to wait for death? After analysis and discussion, the expert group of the cross-border enforcement team concluded that since the small escape prosthetic used by Professor Shimizu was used for escape, it was not necessary to use a fuel cell that I did not know if I could find fuel to replenish it, and that it was the right way to install supercapacitors in a proper manner.

At this time, in the abbot's pavilion, Master Shanren slowly filled the copper lamp with purified standard ghee with an oil pot, and his long flower eyebrows were slightly wrinkled. He wasn't thinking about how Hong Ye's mentality had changed since he left last night, but he was just wondering why the lamp oil had burned so fast in recent days.

"Could it be that because the weather is dry, this wick has become extra oily?"

……

That night, Hong Ye brought a reclining chair and placed it in front of the door, Ye knelt on the palm mat and beat his legs for him, and he had already wandered to the heavens. Some of the little novices in the surrounding monks' liao looked at this side and pointed their fingers, sighing that Uncle Hongye had fallen.

He didn't mean to make a gesture to show the novices, he didn't enter the house just to rub the net—the nearest sentry only covered his doorway, and his own liaison desk had been requisitioned at the beginning of the arrival of the law enforcement team. After all, idleness is idleness, and the liaison desk in the hands of the law enforcement team is not sufficient.

At the height of the fourth floor of the mountain elevator, a slightly sluggish and stiff black shadow wanders through the sparse woodland, stopping and stopping, checking the terrain and orientation from time to time. This distance is already outside the joint encirclement of the cross-border law enforcement team and the local security bureau, and there is almost no ground alert, and the movement of the black shadow seems to be very easy.

Judging by his size, the black shadow is about an adult man of medium height. Carrying a huge backpack, not equipped with the Shura armor, nor carrying an emergency contact desk, he held a flashlight in his right hand to search around, but he didn't see any light from it.

After some calculations, the shadow chose a location. It was a naturally formed cave between the mountains, and according to the map drawn by the electronic bat, the deepest part of the cave was more than 200 meters deeper than his current location, and the relative height was more than 70 meters.

Satisfied with the cave, he untied his backpack and took out four sets of teacup-sized mole cricket insect robots inside, set up their routes, and stuffed them into the cave in one go. When the mole crickets entered the cave, they followed the gap and went straight up, and when they reached the end, they dug in two ways. Whenever the front one runs out, the one behind it refills it, and it returns to the hole to replace the battery.

The man in black's huge backpack was almost entirely full of spare batteries, except for four mole crickets, as if he wanted to open an underground tunnel from outside the encirclement to the top of the mountain.

This digging effort makes it almost impossible to recover energy from the artificial muscles, and the battery drains exceptionally quickly. And because of the lack of oxygen underground, fuel cells are not easy to use here, seeing that the batteries brought are about to run out, and the excavation progress is less than one-third, but the man does not seem to be in a hurry at all.

After the last two batteries were loaded with mole crickets, the man retrieved the last three items from his backpack: two sharp-tailed swifts, and a black rat that looked exactly like the escape prosthetic used by Professor Shimizu.

The man silently counted the time, and when he saw that the remaining two mole crickets had run out of power and returned to the sea, he released the two sharp-tailed swifts one after the other. Then he felt a slight tremor under his feet, and he knew that the last two batteries had exploded.

He took out a wet wipes with C4H10O written on them from his arms, opened them with bated breath, covered it on the black mouse that cracked from his head, reversed the dull flashlight and held it hard, and ignited the wet wipes with a waiting bullet, which exploded violently on the black rat's prosthetic body.

The man patted the collar of his clothes, pulled two tactical eyes from behind his ears and buttoned them to the middle of the bridge of his nose, covering his own eyes with linear pupils that represented nocturnal animals, and ran down the hill without looking back. As the arterial injection of the drug took effect and the heat generated by the clothing, his body temperature rose rapidly, and he became more agile and responsive.

And with the explosion of the battery, in less than three seconds, hundreds of floodlights from various aircraft in the air were all ignited, and five miles down from Huazang Temple instantly lit up into daylight.

Although there was no alarm in the ears of the old humans, the internal channels of the law enforcement team and the security bureau had begun to mobilize urgently, and precise and reasonable instructions were issued by the artificial intelligence command center in an orderly manner to all the personnel who could be mobilized, including civilians like Hong Ye - his task was to stay in place and not run around and get in the way.
