Crossing over reveals a waste's difficult journey home

Fortunately, Jiang Tuan's mind was not completely occupied by eating, drinking and having fun. After thinking for a long time, he thought of something about wax.

Some modern waxes are industrial products, related to petroleum and the like, so this does not need to be considered.

He didn't even know if Daxia had oil. Even if it did, could he still build a refinery or a chemical plant? That was simply unrealistic.

He only knew one way to get wax: from plants.

Jiang Tuan forgot which time-travel novel he had read, but it said there was a kind of insect growing on a tree, and that insect would secrete oil on the tree, which could be used to make candles. The name of the tree seemed to be the ash tree, and the insect was called the ash insect.

Thinking of this, Jiang Tuan told Bai Guo what little he knew about wax to see if the other party knew about it.

Bai Guo didn't know, but he was not discouraged at all. He had been studying medicine since he was a child, and there were still many medicinal herbs he had never seen or used.

Now he suddenly heard something he didn't know and he thought it was very normal.

But just because he didn't know didn't mean that others didn't know. They had a large family and many relatives and friends were traveling far and wide to treat people's illnesses. He could mobilize everyone to help in the search.

By the way, there are some patients who have been treated by their family who can also be activated. As long as Daxia has this kind of thing, he doesn’t believe that he can’t find it.

Seeing that Baiguo was full of confidence and didn't think this was a difficult task, Jiang Tuan was very happy. He thought he was helping the other party solve a difficult problem.

After eating and drinking and chatting with Baiguo for a while, he felt sleepy again. There was nothing he could do as he had not had a good rest these days. He was woken up by hunger before, and now it was hard not to feel sleepy after eating and drinking.

Jiang Huai seemed to be feeling much better. He had helped someone with a small favor, so he went to bed happily without any worries.

Jiang Tuan was sleeping soundly here, but Jiang Qi in the palace couldn't sleep.

It was already very late. He did not eat or go to the harem. He drove everyone out and sat alone in the Wenzheng Hall, silently venting his sorrow.

When sending Jiang Huai and Jiang Tuan away, he understood that even with a lot of preparations, nothing was foolproof. He did not force the two to avoid any danger, as long as they could return safely.

He was worried that Jiang Tuan would not be able to adapt during the journey, and that the two of them would encounter wild animals and bandits, but he never thought that Jiang Huai would suddenly fall ill.

Like Jiang Tuan, when he heard that Jiang Huai was ill, he wondered whether the historical records were not so accurate?

But it was useless to think about those things now. He just hoped that they could get to Eagle Mountain as soon as possible so that they could still have a chance of survival.

However, telling himself that it was useless to be anxious, as a father and an emperor of a country, he could not really remain calm when he knew that his son, the crown prince of the dynasty, was going through a life-and-death test.

When he knew that Jiang Tuan was going to Yingshan, he chose him with his strong rationality and imperial will and decided to give up his son. Now when he is really facing his son's life and death, he feels that he has overestimated himself.

His heart was hurting more and feeling worse than he had ever imagined.

He sat quietly, thinking about the moment his son was born. He was so happy to be a father that he rode out for half the night. When he got home, his parents scolded him, which made his wife, who had just given birth, laugh for a long time.

But he didn't think there was anything wrong with it. He was a son, the eldest son and grandson of their Jiang family, a child he and his wife had conceived together, and his Jiang Qi's inheritance in this world. Before he was born, he decided to give him the best life.

At that time, he was gathering his energy and had not yet started his big business, so he had a lot of free time to spend with his son.

He would dance with joy when his son smiled at him, would wish everyone knew when his son called him "Dad" for the first time, would secretly take his son out to see his new horse when he just learned to walk, and then would be beaten by his parents and run away in fear, and would be blamed by his wife.

When he started his own business, he took his son with him and taught him personally.

And his son did not disappoint his hopes at all. He was extremely intelligent at a young age. He understood many things he just had to say once. Slowly, he grew up to be a qualified prince.

It can be said that Jiang Huai is not only his blood son but also his inheritance, his expectation for the future and the dynasty.

Now, where he can't see, his son is suffering from illness and may die at any time. All his love and expectations may be wasted. How can he not be heartbroken?

He thought about every little detail of his time with the other person over and over again in a self-torturing manner, and he kept thinking about it for the entire night.

When the sun rose and the darkness passed, he became the emperor who seemed invincible again. He even had to hide his worries about his son so that no one could notice anything unusual.

……

After eating and drinking, Jiang Tuan slept very comfortably and contentedly, sleeping from the afternoon till the next morning.

After waking up, he was in a daze for a long time. When he came to his senses, he heard the voice of the system.

"Honey, are you awake?"

As soon as Jiang Tuan heard what the system said, he knew that the other party had something to tell him. He was very satisfied that the system no longer called him in the middle of the night or when he was least prepared. In addition, he had slept well and was in a good mood, so his voice when talking to the system was much gentler.

"What's wrong with the system? Is there anything wrong?"

"Dear, the system needs to be optimized and repaired, so the system will not be able to communicate with you in the next few days!"

Why do we need to optimize and repair it again? Wasn’t it already done when collecting energy before?

In response to Jiang Tuan’s doubts, the system’s answer was that it was impossible to completely optimize and repair the system in such a short time.

In order to save Jiang Huai in time, the system collected energy as quickly as possible, and then used most of the energy to repair the channel to the alien space and take out the medicine.

Apart from these, the system has not fixed anything else, such as the previous problem of being unable to collect energy due to too much energy and too far distance.

After fixing those problems, the system should be carefully checked to prevent mistakes from happening again at the critical moment next time.

What the system said made sense. If such an emergency happened again, Jiang Tuan felt that what would be lost would not be half of his life, but his entire life.

However, before the system left, he couldn't help but ask about the things in the alien space out of curiosity.

"System, what's in your space? Besides medicine, are there any high-tech weapons, mechas, energy swords, or electromagnetic cannons?"

“Dear, there will be those things in the future, but they are all controlled weapons.

The master of the system is a good citizen who abides by the law. How could he prepare those things and bring them to the ancient world? That would cause chaos!"
