Crossing over reveals a waste's difficult journey home

Jiang Qi just wanted to persuade Jiang Tuan so that he could grow up, but after persuading him, he didn't help Jiang Tuan grow, but arranged another task for himself.

Looking at Jiang Tuan's expectant eyes, he finally said nothing more. Just give it to himself. It is better than not listening to advice and thinking that he is meddling too much.

Jiang Tuan talked to Jiang Qi about energy very easily, leaving the problems he couldn't solve to capable people.

This was the second time he had obtained more energy since his last conversation with the system, and he had to discuss how to use it.

"With so much energy, we need to think carefully about how to use it."

Jiang Qi was indeed a little surprised when he heard Jiang Tuan say that telling stories could gain energy.

Fortunately, although he didn't know what it meant to have a rich spiritual life, he understood that sometimes listening to music could indeed make people happy, and he understood it for the time being.

The next step is to think about how to use this method to obtain more energy.

As for the energy collected by other things, he knew it in his mind. As for the problem of obtaining and using energy, he actually realized it earlier than Jiang Tuan.

He came to the same conclusion as Jiang Tuan: the energy used by the system to collect and exchange things had already been determined, and they couldn't change it even if they wanted to, so they could only accept it.

There is no point in dwelling on things that you cannot change no matter how hard you try. It is better to change yourself and try to accept them. Maybe things will go more smoothly.

After thinking for a while, he asked, "Jiang Tuan, what do you think about changing some medical skills? Can the system be changed?"

Jiang Tuan had no objection to changing medical skills. The medical level in ancient times was too poor and people could lose their lives if they were not careful. Changing to some reliable medical skills would be a good thing for everyone.

Also, Daxia was about to go to war with the Huns, and more simple treatment methods should be able to save many lives.

This was a good idea, and Jiang Tuan immediately asked the system.

The system immediately gave a very reliable answer, saying that it only cost 23 energy points to exchange for a Daxia edition of the "Barefoot Doctor's Manual".

This manual is tailored to the actual situation in Daxia and provides treatment and prevention information for some diseases, as well as methods for dealing with some injuries.

Anyone who has read this manual will find it very practical and the energy is well spent.

Only twenty-three out of more than one hundred energies were used, and Jiang Tuan and Jiang Qi began to think about other things.

For example, methods of processing wool, methods of knitting sweaters, methods of making glass, methods of making candles, methods of making paper, and so on.

The two discussed for a while and decided to seek the system's opinion. The opinions given by the system before were all good, and this time there might be better options.

"System, what do you think should be changed?"

"Dear, except for the processing method of wool, the system does not recommend you to change anything for the time being!"

"Why? Is the wool processing method expensive? Isn't there enough energy left to exchange for something else?"

"My dear, the things we exchanged before were mostly things that Daxia needed most or were beneficial to the war against the Xiongnu, so we had to exchange them for energy.

Now that we have replaced most of the things we need urgently, we should consider the problems that will arise later!"

What's the next question? Jiang Tuan was stunned for a moment, then slapped his forehead hard. If the system didn't tell him, he would have delayed something important.

According to the systematic narrative, the main purpose of the Huns' initial southward migration this winter was to rob things so that they could survive the cold weather, and they had no intention of capturing Daxia.

Later, Jiang Huai died of illness. The Huns felt that Daxia was in chaos and it was a good time to occupy some land, so they invaded with the whole country's strength.

Because of the Huns' crazy actions, Jiang Qi had to lead the army in person, which led to him being shot and killed by stray arrows.

Because of this series of chain reactions, Jiang Tuan has always regarded saving Jiang Huai as his top priority.

However, he was very happy to exchange energy for things these times, and Jiang Huai didn't seem to have anything to do, so he felt that this matter was not urgent at the moment.

Now that the system has brought this up, he has begun to reflect on himself, wondering if he has not taken it seriously enough.

"System, was it too hasty for me to exchange energy for something before? I should think about it again. Am I wasting energy?"

"Don't worry, dear. That little bit of energy won't affect anything."

The system's words made Jiang Tuan's heart finally calm down, but then quickly jumped up again, just like riding a roller coaster.

"System, what on earth are you trying to do? On one hand, you told me to think about it later, and on the other hand, you said that the little energy collected wouldn't have any impact. Are you kidding me?"

"Dear, don't get excited, just listen to what the system says slowly!"

What the system said about considering it for the future really meant that it wanted to save up energy to open the alien space as soon as possible and get the medicine that could cure the prince's disease.

It is true that the energy used to exchange things before would not have any effect. That little bit of energy was not enough to even open a crack in the alien space, let alone take things out.

What the system means now is that it has used energy to exchange some knowledge for Daxia. As long as this knowledge becomes reality, Daxia can completely escape its historical fate.

Even if there are other difficulties, as long as we can get through this cold winter, everything else can be dealt with later.

Next, they will change the direction of their efforts. They will no longer collect energy to exchange for knowledge, but will collect energy to open up another space.

Jiang Tuan understood what the system said, but if energy was really that easy to collect, why would he be so stingy and think twice before replacing something?

"Jiang Tuan, what did the system say?"

Jiang Qi sat aside and drank scented tea while Jiang Tuan and the system started talking.

Since he exchanged the tea-making method, he immediately had it sent to the south. After all, tea trees grow in the south, and making tea using local materials is the best way.

Tea cannot be made in a short time and cannot be drunk, so he still drinks ordinary scented tea.

As he drank, he saw Jiang Tuan's facial expression changing from time to time, sometimes relaxed, sometimes nervous, sometimes happy, and sometimes angry. There was no moment of calmness.

Seeing Jiang Tuan like this, Jiang Qi realized that the system might have said something important, so he put down the cup in his hand and couldn't help asking the other party.

"Your Majesty, you have heard about Jiang Huai from the system, right?" Jiang Tuan looked at Jiang Qi and asked carefully.

Jiang Qi nodded. He knew this for sure. Since this concerned his child and the heir to the dynasty, how could he not ask for clarification?

“Since Your Majesty has heard about it, you should know that there is an alien space in the system, from which medicine can be taken out to treat the diseases that the prince will suffer in the future.

The day when the prince falls ill is getting closer and closer, and we need to collect energy as soon as possible to open the alternate dimension."
