Zhang Nan didn't think much about this condition proposed by the system, after all, this is a shuttle through time and space, so it is acceptable for the system to increase the cost of Zhang Nan.

But the most important thing is that Zhang Nan can return to the modern era that he loves and hates.

People are so contradictory, they don't cherish when they have it, and when they don't have it, they miss it.

Although Zhang Nan has nothing in modern times, he is an out-and-out three-nothing young man, and he is a figure who can stir up the storm in Datang.

Jin can talk and laugh with Comrade Li Er, and he can earn a lot of money when he retreats, but Zhang Nan still occasionally misses his modern days.

Now that the system actually has such a service, Zhang Nan naturally wants to experience it.

After all, he came from there.

"Can you ask a question?" Zhang Nan looked at the pretty face of the system and raised his hand and asked.

"Of course, I exist to better fulfill your wishes, and at the same time help you complete your mission." The system said with a smile.

"Can I bring things from Datang to modern times, or bring modern things to Datang." Zhang Nan asked.

Although Zhang Nan has decided to be a thorough Tang Dynastyman, this does not affect Zhang Nan to use time and space to earn modern money, after all, the cultural relics of the Tang Dynasty are worth a lot in modern times.

And Datang also has many things that can't be made, and Zhang Nan also wants to help Datang's science and technology tree climb through modern technology.

After all, Zhang Nan is not a scientist, and some things are only known but not the other, so Zhang Nan can get some things that are no longer practical in modern times in this way and bring them back to Datang to be studied by Datang's craftsmen.

Although this is suspected of cheating, it is the fastest way to improve Datang Technology.

Because this will not make Datang's technology jump too much, and it will also not be subject to the limited thinking of Datang craftsmen and cannot be created.

After all, in modern times, China relies on buying some advanced things from other countries to study its own, so as to narrow the gap with other countries in certain fields.

After all, in some fields, the monopoly of science and technology is a matter of no choice.

After listening to Zhang Nan's question, the system quickly gave its own answer.

"Of course, you can, but the system will charge the corresponding points." System Channel.

"So how do you calculate this point? Is it possible to calculate the points according to how much? Zhang Nan wondered.

"No, the points will be charged according to the size of the object carried by the host, and the bigger the object, the more points will be spent." The system says.

Hearing what the system said, Zhang Nan was relieved, this is not good news, after all, Zhang Nan is more about bringing Datang's small objects to modern times.

As for the machinery that was obtained from Datang in modern times, it can be completely disassembled and transported.

Thinking of this, Zhang Nan couldn't help but praise his wit.

"There is also the question of whether I can take people to modern times." This is the issue that Zhang Nan is most concerned about.

The first point is that although Datang's current medical level can be said to be at the forefront of the world, it is still too backward in Zhang Nan's opinion.

It's okay to be young now, but when you're older, you can't keep it from having a disease or a disaster, especially an acute illness, Zhang Nan doesn't want to lose his family because of the backwardness of medical standards, so it would be great if he could bring people with him through time and space.

The second point is that after Li Er asked himself, Zhang Nan began to think about his way out, if he could be an official for a lifetime, it would not be bad.

But what Zhang Nan is most afraid of is that someone like Lao Li who is seriously suspicious will suspect him one day, and then Datang will have no place for himself, so Zhang Nan has to prepare for his own future.

If Zhang Nan was alone now, he would have seen it, but the problem now is that his home is here, with children and a wife, so Zhang Nan has to consider safety.

If Lao Li turns his face one day, then there is a safe refuge anyway.

After listening to Zhang Nan's question, the system seemed to have expected it, and then smiled: "Yes." However, points will also be charged. ”

"Really?! That's great! "As soon as I heard that I could take someone back, it was the best, which was undoubtedly a double insurance for my net worth.

"Host, do you have any other questions?" The system asked.

"Not yet." Zhang Nan said after a little thought.

"Since there is none, the host can exit the system, because there are external forces from the outside world trying to wake up the host." After the system finished speaking, Zhang Nan felt that it was dark in front of him again.

It's just that this time, Zhang Nan is sober and his eyes are dark.

And such sobriety comes at a price.

Before Zhang Nan opened his eyes, he felt a sharp pain in his feet.

So Zhang Nan shouted and sat up from the bed.

It didn't matter if Zhang Nan got up, but he jumped Cui Yue, who was guarding the bedside.

But the shock quickly turned into a surprise.

"Lang Jun! You finally woke up, you were dizzy for three days, and the concubine thought you would never wake up again. ”

Cui Yue said, and pounced on Zhang Nan with a look of grievance.

Seeing this, Zhang Nan also took Cui Yue in his arms. Although Zhang Nan was also very surprised why his Yishun in the system became three days in Datang, Zhang Nan was also distressed when he saw Cui Yue like this.

But the heart is distressed, and the body is painful.

Zhang Nan looked down and found that his feet were full of silver needles at some point, and Sun Simiao was also standing aside and looking at Zhang Nan with a smile.

is the so-called ten fingers connected to the heart, and Zhang Nan's toes have not escaped the punishment of the silver needle, and basically have a silver needle inserted.

"Lang Jun, you woke up thanks to Sun Daochang's excellent medical skills, if it weren't for Sun Daochang's continuous stimulation of your acupoints with silver needles for the past three days, Lang Jun, you wouldn't have woken up so quickly." Cui Yue was also very happy when he saw Zhang Nan wake up.

And Zhang Nan is sweaty.

After doing it for a long time, I have been punished for three days.

"Qingquan, how do you feel now?" When Sun Simiao saw that Zhang Nan woke up, he thought that his silver acupuncture point had an effect, and happily stroked the beard on his chest.

"My feet hurt."

Zhang Nan is also very concise and clear, because Zhang Nan is really in pain.

"It's right, my stabbing is a big acupuncture point on the soles of the feet, if it doesn't hurt, it means that Qingquan has something wrong with your body."

“……”

"It's okay, Rong Laodao will give Qingquan today's needle to you to finish, so as to ensure that nothing goes wrong."

"Don't, Daoist, you'd better be okay, let me go quickly."
