At this time, everyone was still discussing the mechanism for opening the three single stone doors. Wang Fugui had once again started to check around, trying to find the mechanism for opening the stone door.

Chen Jian quietly walked to the corner and thought about what the light that had just passed by his mind, because Chen Jian knew very well that he had thought of what he had thought of, but he needed to straighten out in order to find out what the light was, that is, what he thought of.

Chen Jian stood in the corner, thinking quietly.

Seeing Chen Jian staying away from everyone, Xiao Yurou stepped forward and wanted to walk over, but was pulled by Xuan Mingzi, shook his head at Xiao Yurou, and then silenced everyone.

There is no doubt that Xuan Mingzi had already seen Chen Jian's condition at this time, and knew that Chen Jian was thinking about something, so that he would not let everyone speak out to disturb Chen Jian's ideas.

The first thing Chen Jian thought of was what Wang Fugui said, because Wang Fugui was an expert in mechanism technology. Although he was not good at expressing himself, he expressed the essence of ancient mechanisms.

Eastern civilization has more than 5,000 years of history, and has historical records and unearthed cultural relics as evidence. It is only about 3,000 years old, and the earlier two thousand years was the ancient times and an era of mythology.

There is no historical record to check in this era, and the very small number of cultural relics unearthed are not enough to reveal the outline of that era. What remains are more myths and legends.

However, one thing is certain, neither the ancient times nor the era with historical records is a modern science and technology society.

When voice control is turned on, Chen Jian and Wang Fugui have the same viewpoint. He does not think that the ancients had such a high level of technology.

After Chen Jian thought of this, he followed his own ideas and said that the voice-controlled things that are turned on may not be accessible to the higher-end ones, but the voice-controlled lights are something that everyone is familiar with.

Since the voice-controlled light is voice-controlled, its principles must be the same.

What Chen Jian was thinking about at this time was how the voice-controlled light was turned on. The principle was actually very simple, or the essence had not changed. It was the energy transfer that Chen Jian mentioned earlier, and the starting power of the voice-controlled light came from the sound, that is, the voice-controlled light was turned on when the voice-controlled switch received the sound.

However, the voice-controlled light will not be turned on during the day, because the voice-controlled light will have photosensitive elements.

There is a microphone and photosensitive element in the voice-controlled switch. When the ambient light is strong enough, the photosensitive element control circuit will make the switch in a disconnected state, that is, the off state. This causes the voice-controlled light to not receive the sound signal during the day, so it will never turn on during the day, and naturally it will not light up.

When the ambient light is not strong enough, the control of the photosensitive element no longer works. At this time, the microphone starts to work. When there is a strong enough sound outside, such as a clapping sound, the microphone picks up the sound signal and turns the switch on, that is, the voice control light will light up.

After the light is on, the circuit is turned off and the circuit is turned off after a certain period of time. At this time, the voice-controlled light will be turned off!

The photosensitive element does not need to be considered, and the extension of the shutdown circuit does not need to be considered. It only needs to consider the nature of sound control.

Its essence is still the propagation of sound. Sound is a sound wave generated by vibration of objects. It is a fluctuation phenomenon that is transmitted through medium and can be perceived by the auditory organs of living animals.

There are many media that sound propagates, such as air, solids, and liquids, which can transmit sound.

When people talk and talk, it is the same as voice-controlled lights, that is, sound waves spread through the air and are received by the other party.

Its essence is sound waves, which is the energy generated by the vibration of an object!

The voice-controlled light can also be regarded as a mechanism, but the principle has not changed. Turning on the voice-controlled light also requires the vibration of the sound to provide the source power for starting the voice-controlled switch.

However, although the principles are the same, voice control is obviously something that modern high-tech can do. In ancient times, there was no electricity, so it was obviously impossible to achieve such a level of voice control.

After Chen Jian thought of this, he began to think about the journey from Shimen to here again.

The first thing to think about is the two huge master doors. The machine is opened and the door is right next to it. Pull the bronze metal ring on the right hand to drive the bronze chain and then drive the gears, thus realizing the entire transmission process. When closing the door, you only need to pull the bronze metal ring on the left to achieve reverse operation.

Next is the passage that Chen Jian and the others walked through, which was the chain board mechanism. Wang Fugui had already explained the principles of this mechanism, and he also detected the correct path step by step. That is, they only came here after cracking the chain board mechanism.

After Chen Jian thought of this, the light that passed through his mind had a clear idea.

The voice control opening is excluded not only because the voice control requires high-tech support, but also because there is an essential difference between the sound control and the stone door opening and the chain board mechanism here.

The difference is that voice control is not required to be opened, and the stone doors or chain board mechanisms here need to be contacted before they can be opened and triggered.

This difference can actually be regarded as the difference between ancient and modern times. In ancient times when technology was underdeveloped, any mechanism triggered must be like contact. Now is the era of science and technology. If a mechanism is set up, it can be triggered without contact.

I won’t talk about voice-controlled lights anymore. Nowadays, many places that require high-level security are used, and the use of infrared is also a non-contact mechanism.

The principle of infrared alarm is that when the infrared ray emitted by the transmitting point and the receiving point. When the infrared ray emitted by the transmitting point is irradiated to the receiving point, the alarm device is in a closed state. When someone passes by, the infrared ray will be blocked, causing the infrared ray to irradiate on the person. The receiving point cannot receive the infrared ray and then starts an alarm.

Alarms are essentially mechanisms. If the alarm is replaced and set as an offensive weapon, modern technology can be easily done. It is completely easy to make weapons attack objects that are not affected by infrared rays.

This is also the reason why Wang Fugui said before that if the ancients had reached this level of technology, they would have died under the authority for a long time.

Judging from the exquisite design of the chain board, if the ancients mastered high technology, they would probably be a hundred times more capable than modern people in setting up mechanisms.

"The agency must be here, but one thing is certain, it is 100% contact-type." Chen Jian said at this time: "I still haven't figured it out. Let me think about it again, maybe it will be helpful for finding the agency!"
