Siheyuan: Returning from studying abroad, with extraordinary understanding

There are two stages in the process of human cognition: sensory cognition and rational cognition.

There are two ways to acquire knowledge: one is through practice, and the other is through learning.

There are differences between the two. Knowledge gained through practice is more intuitive, the understanding is deeper, and the situations encountered are more complicated, but the disadvantages are also obvious. It takes a long time, and human life is limited, so it is impossible to gain everything through practice.

Moreover, some practices have already been done and experienced by your predecessors, so there is no need for you to experience them again personally.

For example, some people say that arsenic is poisonous, but you don’t know that. But if you experience it yourself and eat it directly, you will die.

So, the solution is to learn, learn the knowledge left by our predecessors.

Just like Lin Changqing, although he is smart, without the books left by his predecessors, it would be impossible for him to master so many skills so quickly.

Whether it is fortune-telling, predicting good and bad fortune, or mental treatment and traditional Chinese medicine treatment methods, he learned all of them based on what he learned from his predecessors.

Without the knowledge of his predecessors, no matter how smart he was, he would not be able to find a solution so quickly.

Lin Changqing does not think it is shameful to learn from predecessors, nor does he look down on the ancients just because he has a good understanding.

The purpose of learning the knowledge left by the ancients is to promote it, not to use it for comparison.

Of course, some knowledge is no longer applicable in this era, so it should be abandoned, or knowledge that is in line with this era should be developed.

Back to learning, the knowledge learned indirectly is one-sided and is knowledge in an ideal state, so it needs to be practiced again.

Only through specific practice can you have a deeper understanding.

Otherwise, you will become a so-called walking bookcase, who only knows how to talk big but has very poor hands-on ability. This is a typical example of not learning well.

Things are constantly developing, so theoretical knowledge must also develop and cannot be complacent. Otherwise, reality will be different from what you have learned.

In this case, what contribution and development can we talk about?

Therefore, direct practical knowledge and indirect learning knowledge need to be combined.

What is the purpose of learning? Of course, to guide practice!

If we study but do not put it into practice, what is the point of learning?

There are special circumstances for Lin Changqing to learn the knowledge of his ancestors.

His brain is more powerful than a supercomputer and can simulate a variety of situations. When learning knowledge, he makes various simulations in his brain. Therefore, what he discovers and masters is more comprehensive and more than other learners.

He can use his brain to simulate real situations based on actual conditions, so he can distinguish the true from the false when learning knowledge, draw inferences from one example and explore new ideas.

Therefore, after eliminating the false knowledge he has learned, what remains is real and can be directly used in practice.

Therefore, his method of using Qimen Dunjia to block the monsoon circulation is feasible.

The ability of divination has long been used in reality, and the results are always exactly the same as reality.

Moreover, he used this method to block the monsoon circulation, and he also predicted it, and the result was auspicious!

Therefore, as long as he lets people build temples at special locations in coastal areas this month, they will be able to withstand this flood disaster.

This is why he was completely relieved.

When he came back from visiting his relatives, he started to build the temple.

However, I will have to tell my leader later and ask him to arrange for people to build it in advance. When the time comes, I will go there to bless the formation myself.

Thinking of this, Lin Changqing suddenly found that it was very difficult to contact his leader.

He had to find a way to create a communication tool.

Future mobile phones and cordless phones will require chips, but how can they be manufactured without photolithography machines?

Now, we don’t even have silicon wafers.

Lin Changqing suddenly thought of his mental power, which could be used to engrave formations on jade, so could he make a few jade talismans for communication?

Wow, we skipped the electrical age and entered the age of cultivating immortals, right?

Lin Changqing thought about it and felt that his idea was feasible and there was nothing wrong with it.

You know, quantum science originated in 1900. By this time, it had been developed for 49 years. Although the development was slow, there were still some theoretical knowledge worthy of Lin Changqing's recognition.

For example, quantum entanglement was proposed in 1935.

Isn’t it an application of quantum entanglement to make a communication jade talisman yourself and connect it?

Therefore, the communication jade talisman is quite scientific.

Lin Changqing simulated and studied it in his mind and found that it was indeed possible.

Engrave the formation on the jade, then inject your own mental power and blood power into it to activate the formation, and the two jade talismans will sense each other.

Mental power and qi and blood power are of the same origin, can sense each other, and are real.

For example, although science cannot explain the blood connection between twins and close relatives, the connection exists, which indicates that quantum entanglement may be the cause.

Of course, simulation is not equal to reality. Lin Changqing tried to sense the protective jade talisman that he gave to his leader, and unexpectedly he actually sensed it.

However, the sensation is very weak, only a vague one, and can only roughly sense the direction.

This is enough!

This has proved that his theory is correct.

Lin Changqing thought of the plot in the immortal cultivation novels, where jade talismans for communication required spirit stones.

But I don't have a spiritual stone. If I use my mental power and blood power to engrave it on the jade, every time I use it, it will consume my blood power.

It will be consumed quickly, and jade is fragile and easily damaged.

Lin Changqing quickly thought of a solution.

In his small world, there is a spiritual spring. The spiritual energy in the center of the spring is rich. He can use a formation to lock the spiritual spring in the jade talisman, acting as a liquid battery. In this way, the consumption of the jade talisman will be reduced.

No need to charge frequently.

In order to solve the consumption problem, Lin Changqing began to solve the problem of jade hardness.

This is easy. Just carve a small Vajra formation.

After considering all aspects, Lin Changqing began to carve the formation on it.

Speaking of which, this communication jade talisman is similar to a walkie-talkie.

The walkie-talkie consists of several parts: switch, receiving signal area, antenna area, signal amplification area, sound-to-electricity conversion, and sending signal area.

Lin Changqing's jade talisman also has a corresponding formation.

Switch - activate the formation.

There are four major formations: receiving formation, amplifying formation, and sending formation.

The amplifying formation is not used to amplify transmitted information, but to amplify the induction between the two jade symbols, which is the antenna.

In comparison, the communication jade talisman is simpler, with only four parts. As long as the formation is activated, the message can be transmitted.

The receiving formation and the sending formation are actually a pair. As long as they correspond one to one, the receiving formation can receive the information from the sending formation.
