Although He Ping did not have the confidence to rely on normal methods to open such a secret door, however, he quickly reacted that this door should not be locked, power supply, if the previous heating cable was not found, He Ping may subconsciously think that the power supply has been interrupted, but now, he understands that the power supply of this door may continue to be maintained, and the power supply equipment should also be in this hidden room.

After He Ping looked at it again, he also found the interesting thing about this hidden room, the power supply equipment is in the room, and the power supply equipment has only three functions, one is to supply power to this secret door, so that the authentication system of the secret door can operate normally, not to lock, the second is the lighting in the room, and the last one is to charge an emergency lamp, the energy supply of these three places is completely unique. The power supply system in the building is not affected by the outside world.

The rest is to see if the power supply equipment inside can operate for so long, but it is not difficult to understand that the power supply equipment in this world uses bioenergy, compared to the fossil energy of the main world, it may be difficult to produce high voltage and current, but the staying power is definitely higher, and whether it is the certification equipment on the secret door, or the lighting equipment, in fact, it does not need high voltage and current support, and the power is also pitiful.

Besides, the lighting equipment inside is not turned on, naturally it does not consume electricity, after the battery of the emergency light is full, there may be loss if it is not used for a long time, but the electricity consumed is certainly not much, the most power-consuming should be the authentication system of the secret door, because it needs to be always on, but because the power is very low, even after three years, the bioenergy of the power supply equipment has not been exhausted.

He Ping is still lucky, although the bioenergy of the power supply equipment inside has not been exhausted, but three years have passed, no matter how low the power consumption is. The amount of electricity consumed is definitely a lot, plus the short circuit of those two cables, the power consumption will definitely rise, so He Ping can be sure that the power supply equipment will definitely not be able to operate for too long, even if it is stopped immediately now, He Ping will not feel any strange.

If the power supply equipment stops working, then naturally there will be no cable heating, and the authentication system of the secret door will stop working, and the secret door will be locked. If you don't look closely, you can't even find out about the existence of the hidden room, at least He Ping only found out after seeing the abnormal situation with a thermal imager, of course, if the branches of the Divine Tree Group in every place have such a room, the surviving high-level officials of the Divine Tree Group know the situation here.

With those distracting thoughts out of his mind, He Ping began to carefully observe the secret door, although it was not locked, but he didn't know how to get the secret door out. He Ping, who didn't know the authentication method, naturally couldn't have entered through normal means like the owner of this office, but this was not difficult for He Ping. In terms of space, He Ping's attainments are not low, at least this hidden room is not difficult for him.

He Ping first separated the short-circuited cables. In order to allow the power supply to run for a longer period of time, he left a coordinate in the office with the space mirror, and then teleported directly into the hidden room with the blink skill. The cooldown time of the flashing skill is very long, if you don't leave a coordinate outside, it's easy to get in, if you can't find a way out, then if you want to come out, you have to wait until the skill cools down, He Ping doesn't want to do that kind of stupid thing.

There is no obstacle to flickering into the room, of course it is pitch black in the room, because it is a completely sealed space, so even the night vision device has no effect at this time, but at this time He Ping doesn't need to adapt, plus there are no zombies here, so he directly took out a few emergency lights and put them in a few corners of the room, and in an instant, the originally dark room became much brighter, and the scene inside was also presented in front of He Ping.

There is a power supply device in a corner of the room, although the specific model is not clear, but look at the appearance, this should be a high-end product customized by the Shenshu Group, and the kind of bioenergy generator used by Nina who has seen it in the camp is very different, it is estimated that both the service life and power generation efficiency are much better than those in the camp, otherwise, it is impossible to operate until now.

There is nothing strange about the power supply equipment, the strange thing is that there is not only one power supply equipment, the reason why He Ping just saw the situation in the room clearly, and focused on the power supply equipment, a big reason is that there are a total of two power supply equipment in this room, when he used his perception to check, he did not continue to go deeper after seeing a power supply device nearby, but now, he saw another power supply equipment in the deeper part of the room, and the power supply equipment was also in operation.

The power supply equipment near the office is the same as He Ping's previous perception, which is to power the authentication system, lights and emergency lights, but the power supply equipment in the depths is different, only one cable stretches out, and the other end of the cable is connected to a device like a freezer, something similar He Ping has seen in the camp and the waste treatment plant, it should be the portable refrigeration cabinet of this world.

He Ping didn't pay attention to the freezer in a hurry, but with the help of the light of the emergency light, he went through the whole room in large quantities, and found that although there were a few shelves in this room that should be used to put things, the shelves were empty, and the place against the wall was a large safe.

He Ping lowered his head and thought for a while, it should be the owner of this room, that is, the owner of this office, and it is very likely that he is the top person in charge of the branch of the Shenshu Group here, before the outbreak of the virus, he entered this hidden room, took out the things inside, and then locked the secret door, as for where the things went, it is not He Ping who knows, but the lockbox that he got in the conference room before should have a little clue, after all, the identity of the skeleton is definitely not simple, Maybe it's the owner of this office, and the freezer, maybe there's something in it.
