After waking up, Zhang San felt that nothing had changed. However, in the next moment, everything seemed to be different. However, Zhang San couldn't tell exactly what was different.

However, there was one thing he was sure of, and that was that as a thousand-year-old family that had become doctors through long-term illnesses, the Gu family's elixirs were indeed quite good. He had never expected that they could even save a person in that condition.

After moving his qi and blood a little, Zhang San was surprised to find that after experiencing last night's life-and-death battle, his own qi and blood were not only not damaged, but instead improved under the nourishment of the elixir.

According to the combat power standards of this world, excluding his supernatural powers, Zhang San's normal combat power has already reached the middle level of Class B.

No matter in his past life or this life, as a hard-working player, what Zhang San hated most (jealousy makes me split apart) was those big spenders who spent a lot of money on games. But he never expected that, now he has become the person he hates the most.

The young man didn't know the sweetness of soft rice, and mistakenly regarded Loli as a treasure! As expected, once people get older, their perception of many things will undergo subtle changes.

But unfortunately, because of the system, he probably won't be able to find a Taoist partner with whom he can resonate with his soul in this lifetime. After all, it is very difficult to find someone who has the same or similar experiences as him.

However, now does not seem to be the time to think about these things. Because he has traveled through the other world for 24 years, he must quickly summarize the previous information. Only in this way can he ensure the survival of his true self in this world.

If this kind of thing had happened in the past, it would not be impossible for Zhang San to do it with his brain, but it would definitely take a lot of time, conservatively estimated to be at least more than ten hours.

However, thinking of the experience of Sai Weng in "Huainanzi·Human Training", Zhang San realized another truth: "Misfortune often leads to blessing, and blessing often leads to misfortune."

Indeed, this adventurous fusion behavior was very dangerous. It can even be said that if it weren’t for Gu Xuanyan, Zhang San’s ego consciousness might have disappeared.

But if you think about it from another perspective, he did not gain nothing. At least his cultivation had improved, and that could not be faked.

Moreover, compared with the gains that followed, Zhang San did not take this improvement in cultivation seriously at all; and when mentioning Zhang San’s gain, we cannot avoid another person - Sherlock Holmes!

The latter was a household name all over the world in his previous life. When you mention Sherlock Holmes, what is the first thing that comes to your mind?

Detective? Sharp insight? High IQ antisocial disorder? Indirect creator of Conan? Indirect cause of Neon Massacre behind the scenes? All of these count!

But for Zhang San, what he paid more attention to was the skill shown by Holmes, called the memory palace, or the way of memory.

To be honest, because of his good aptitude, Zhang San also privately practiced this way of memorization that only exists in theory after finishing watching the TV series in his previous life.

However, the result is predictable. This skill that belongs to genius is not something that ordinary people like us can master. In order to cope with various exams, Zhang San finally chose to construct a memory method that is more suitable for him.

This sounds okay. After all, it is his special way of memory that helped him complete the integration of the memories of the Demon Slayer world.

But human power is limited after all. When facing the memories of his second life (Full-time World) one after another, Zhang San's original way of memory completely collapsed. This is also the most fundamental reason why his consciousness is wandering but difficult to gather.

It is not that Zhang San really saw through life and death at that time, and had an epiphany. As the saying goes, even ants want to survive, let alone humans? The reason why Zhang San was able to look down on life and death was actually because his memory had collapsed. He forgot to survive and even didn't know what survival meant.

In short, he only had instincts at the time and could only react to external conditions, but he could not exert his own subjective initiative.

If you continue like this, you might die. Do you want to continue? Continue. There is a voice coming from the outside world. Do you want to think about who the other party is? Think. …

That's how it was. All actions seemed to have become multiple-choice questions, and the only thing Zhang San could do at the time was to make choices. Unfortunately, with his memory collapsed, he couldn't even understand what these choices meant.

If he was lucky, he could naturally choose the option to survive, but it was obvious that his luck was not very good at that time.

However, there is a saying that one cannot build without destruction. When the original way of memory is broken and his brain has sufficient nutrition supply (pills), the memory palace that originally existed only in theory is no longer a castle in the air or a mirage.

Now, Zhang San seems to have the right to glimpse the world of geniuses! Abandon all external interference and sink your mind into thinking. In the words of the cultivation world, this should be called meditation. This is the first step in building a memory palace, but this step has already excluded 99.9% of people from the palace.

Fortunately, Zhang San has already mastered the world of understanding, so this is not difficult for him.

Although the memory palace is usually called a palace, the specific appearance of the imagined building varies from person to person.

For example, the buildings in Holmes' mind are "court" and "Baker Street", while the building in Zhang San's mind is "Infinite City".

Moreover, unlike the huge building complex in Sherlock's mind, the building in Zhang San's mind at this time seems very cramped. Not to mention it can be called a "city", it can only be regarded as a very crowded room filled with various memories.

But this is not a difficult task. As long as the method is correct, even if it is just one room now, there is still a chance to expand it.

The room in Zhang San's thinking palace is not big, only less than 80 square meters, but the strange thing is that there is no space for daily life inside, and all the useful space is occupied by bookshelves.

If you count carefully, there are not many bookshelves, only four!

"In the first life, Fu Yuqin, it's not him; in the third life, Qin Chi, it's not him either; oh, I found it, it's here!"

Looking at the bookshelf in front of him with the words "Second generation, Zhang San, with the courtesy name Sirui" written on it, a long-lost smile appeared on Zhang San's face.

He didn't know why, but when he felt the vague sense of crisis around him, his blood, which had already frozen, showed signs of boiling again.

Maybe this is just his nature! "Calm down. Now is not the time to get carried away."

After slapping himself in the palace of thought, Zhang San finally immersed his mind in the book.

All of a sudden, words like "the third year of Qi Ling, Ya Ya, Wang Bo, Gu Xuan Yan, Dou Su..." flooded into his mind, and this is the horror of the Palace of Thought.
