The new discovery made Ye Jinyu fall into a deep depression, although there are indeed many advertising spaces in Chang'an City, which is a golden land for advertising to be developed, but he really just thinks about it, just thinking about it, and has no intention of opening a copy shop here.

Otherwise, I will change my career, and with the funds in my hands now, it will be more than enough to open a single store, such as opening a gold shop, such as a small shop that recycles gold in the stairwell on a street corner; Will you be able to smuggle gold in this way?

Who knew that Ye Jinyu had just had such an idea, and his head was like being stuffed with a bunch of information, and he had an understanding of the space-time gate bound to his left hand.

The official name of the gate is: Boundary Gate - Beta, the maker is unknown. This is the message that the space-time doorkeeper gave him. The function of the door is to detect what kind of impact it will have on the development of different time and space when practitioners in different industries arrive at opening up different time and space; Therefore, the door will limit the items to be carried according to the occupation and identity of the binder.

I don't know where the design and manufacture of this door is sacred, and the egg hurts tightly. As Ye Jinyu guessed before, it is limited by this rule, and can only carry the materials that can be used in the production and life of the copy shop.

As for Ye Jinyu's idea of changing an industry, Jiemen said that in order to standardize the behavior of the binders and accurately detect the real role that the binders can play in another time and space, they are not allowed to change careers halfway, and once they change careers, it is equivalent to giving up the time and space gate; In order to ensure that the space-time gate is not leaked out, those who abandon the space-time gate will be humanely destroyed.

In addition, there is another usage note: the daily use of the space-time gate consumes the physical energy of the binder; The upgrade of the space-time gate requires the consumption of space-time energy.

How does space-time energy come from? According to the message, it can be obtained by changing the development of the original space-time, and the greater the amount of change, the more space-time energy can be absorbed.

As for what the upgrade is, it is not mentioned in the vague information, and Ye Jinyu does not know; However, Ye Jinyu speculated that it may be the opening of a new type of storefront; If that's the case, be sure to open a gold shop next time! Ye Jinyu thought so.

The information focuses on space-time energy, which is very useful, not only can it be used to upgrade the boundary gate; When the binder has a special need, they can consume a certain amount of space-time energy, and temporarily include items that have been rejected by the system into the types that can be passed. For example, the corpse that Ye Jinyu threw into the lava hell last time was originally not on the list, but it was because of Ye Jinyu's strong will that the procedure of the boundary gate consumed space-time energy to let Ye Jinyu throw the corpse over. However, this kind of supernumerary operation consumes a huge amount of space-time energy.

As for how much space-time energy he has, the boundary gate did not quantify this thing, nor did he give specific data, and Ye Jinyu could only explore it by himself like a blind man.

In general, the news given by the boundary gate is not much, but at least let Ye Jinyu know what this door is about, and also estimate his carrying range and some ways to use the door.

Ye Jinyu felt that life was so painful, a once-in-a-lifetime time and space door was touched by himself, but he had this inexplicable restriction, he opened a copy shop, did he still run to the Tang Dynasty to open a copy shop? Isn't that funny?

If nothing else, what kind of equipment such as photocopying graphic advertisements does not use electricity? Can the Tang Dynasty provide electricity?

Well, maybe it's really possible, it's not that Li Chunfeng gave the thunder talisman, that thing is too unreliable, it's not good to scorch the equipment directly; Rather, it is possible that the power generation equipment can be sent through the space-time door, because the power generation equipment can also be used by copy shops.

As long as there is electricity, then many things can be done, the machine can be started, and the factory can be started; Even with excess electricity, it can also be supplied to Datang for development, and it cannot be said that Datang has directly entered the electric era.

It doesn't seem particularly difficult to accept when you think about it!

It's just that even if you can open a factory here, what's the use? The money earned here can't be brought back to modern times; If you want to bring some valuable seals from here and sell them for money, you can get any books and the like, and there is no need to go out of your way to open a factory.

This kind of thinking that a little wealth is peace is influencing Ye Jinyu. It seems that the person who created the space-time gate only thought about letting different people travel through time and space, but didn't think about what if the bound person was lazy?

After all, Ye Jinyu is still a hot-blooded guy, with seven emotions and six desires, and he is not yet lazy and has advanced cancer; I can't help but wonder what I'll do after making money.

Come home rich or famous? This is a must, the biggest wish of the parents in this life is to hope that the two brothers will get ahead, and if they don't go back to their hometown to show off when they are developed, so that their parents will be happy and happy, it will not be a night trip in brocade.

But after that, do you want to ask for a wife, give birth to a baby, and live a happy life as a family from now on.

People have to have some ideals.

Boss Wang said that it is best to set a small goal that can be achieved first, such as I will earn 100 million yuan first. What about yourself? If he could get those few stone veins through Li Yuan, 100 million was really not a goal for Ye Jinyu.

Money is not a problem, how do you set yourself a small goal that you can achieve? For example, let the space-time gate be upgraded to the next level, or change a space-time first, and transform Datang into a global domination according to its own ideas? Let the Tang people be the masters of this planet?

Ye Jinyu himself has not yet developed, and he is already thinking about helping the world.

Thinking of setting a small goal for himself, Ye Jinyu's head began to grope deeply.

In fact, although the space-time gate is limited to this and that, it limits itself to the scope of the copy shop; But if you think about it more relaxed, in fact, what you brought over is not just a copy shop; In fact, human beings have accumulated 1,500 years of knowledge, lessons, technology, culture, political and economic systems. These cultural knowledge and lessons are far more helpful to an era than what food and clothing to bring.

Although Ye Jinyu's own individual is weak for a time and space, he is standing at the height of 1,500 years and looking down on this era; With 1,500 years of development and tens of billions of ancestors and modern people, he has endorsed him.

It doesn't seem hard to accept when you think about it this way!

Continue to look deeper into this space-time gate, all kinds of signs are forcing yourself to develop in the Datang space-time, count it carefully,

The first point is that you must be developed in modern time and space, and you must get ahead;

The second point is that he has the intention to change the development trajectory of the Tang people and even the entire planet in the Tang Dynasty time and space;

The third point is that this bird's space-time gate needs space-time energy to be upgraded;

Fourth, space-time energy needs to change the development trajectory of this space-time to obtain;

These four also complement each other and do not conflict.

In that case, let me start jumping and go to the pinnacle of the two planes. As for the small goal of 100 million, I took the time to complete it for him.

With a goal, Ye Jinyu has a heart in mind.

……

The eunuch had been waiting outside, not daring to go far; Hearing the sound of crackling and throwing things inside the door, he waited very anxiously, but he didn't dare to peep into the movements of the gods, so he could only continue to be anxious.

After a long time, the sound inside the door finally stopped, and there was no more movement; The eunuch had the courage to shout at the door: "Godman, Godman is here?" ”

Ye Jinyu was thinking about his own affairs, and he didn't hear the eunuch's voice, so he didn't answer.

But the eunuch persistently shouted, "God-man? Is the man of God well? ”

finally alarmed Ye Jinyu, and when he heard the voice of the eunuch, he remembered that he should now take the gunpowder formula to help the Tang Dynasty emperor make gunpowder and solve the urgent problem of Turkism. Well! It's decided, and change starts with gunpowder!

Ye Jinyu patted his ass and stood up from the ground, and shouted outside the door: "Wait a minute, it'll be fine right away." Listening to the eunuch's voice ceased, he picked again among the things that had been thrown at him; It doesn't seem to have been thrown over, and I have to wear it back again.

After sitting on the ground for so long, the state has recovered slightly; It shouldn't be a problem to cross over again.

Opening the door again, Ye Jinyu returned to the copy shop. The printed gunpowder data lay quietly on the computer desk, and after copying it, Ye Jinyu wanted to go back to the door. His eyes swept over the electric car, and he suddenly remembered how hard he was hiking in Chang'an City. couldn't help but roll his eyes, and he wanted to push the electric car to the Tang Dynasty.

The battery pack of the electric car was installed by Wang Zhiqiang on the night when it came out of the police station, and the battery was also charged overnight, and it was no problem to ride twenty or thirty kilometers; If you walk twenty or thirty kilometers by yourself, you will definitely vomit.

Thinking of it, he folded the information in his hand in two and stuffed it into his pocket, took out the key to open the lock, sat on the seat, held the handlebar with both hands, twisted his right hand, and slowly opened towards the time and space door that had not yet closed.

When it hits the door, it stops as if hitting a wall.

Ye Jinyu couldn't figure it out, and said to the door: "This is your mistake, I can use an electric car when I open a copy shop!" This is a delivery and pick-up tool, why not give it over? I don't know if it's Ye Jinyu's illusion, after he said this, the soft light of the space-time gate flashed, as if he was calculating Ye Jinyu's rhetoric or hesitation;

When Ye Jinyu drove the car towards the space-time gate again, it actually passed, passed, went, went.

When he really saw that he was in a house in the Tang Dynasty, Ye Jinyu was confused; He didn't expect that the space-time gate, which had always been particularly mechanical in his thinking program, could actually be discussed. The space-time gate that can be discussed, countless thoughts instantly turned in Ye Jinyu's head. Electric cars can be discussed, but what about other things? For example, gold, which is the currency earned by copy shops, can it also be accommodated?

Just as he was thinking about it, the eunuch outside began to call again: "Godman? Ye Shenren? ”

Hearing this annoying sound, Ye Jinyu knew that this would be impossible to test; Got on the electric car and shouted to the door: "Open the gate." ”

The eunuch was waiting for this, and when he heard this, he immediately opened two doors, and then saw the man of the gods floating on a two-wheeled cart. The two wheels were strung together and did not fall, and the eunuch's eyes were straight.

"What are you doing in a daze? Hurry up and help me get it out! "Although the man of God floated over, the electric car could not float, and the wheels still had to touch the ground; The threshold of this house is too high for electric cars to pass.

"Oh!" The eunuch hurriedly stepped forward to help.

The electric car is no heavier than a motorcycle, and the two adults easily lifted it out of the gate and then down the steps.

Descending to the flat ground, Ye Jinyu got on the car again and said to the eunuch who was still stunned: "What are you waiting for? Hurry up and get in the car and sit in the back. As he spoke, he patted the back seat with his hand.

"God-man, this god car won't fall." The eunuch asked hesitantly, the car with two wheels strung together was a bit unreasonable.

"Put your heart in your stomach, don't I control it."

Looking at the indifferent expression of the godman, the eunuch gritted his teeth, and said in his heart that I would give up my life to accompany the gentleman, and I learned from the godman to sit in the car.

It's just that the costumes of the Tang Dynasty are complicated, no better than the pants worn by Ye Jinyu; After a while, the eunuch was still gesturing how to straddle over. Ye Jinyu was impatient and said, "You are like a woman, sit sideways, put your legs to the side." ”

The eunuch got into the car according to his words, and after he sat down, Ye Jinyu shouted: "Let's go, let's start with gunpowder and change the world!" Then with a twist of the handlebar, the electric car whined and rushed forward.

The god man's chariot really won't fall, sitting on it is like flying, at this moment, the eunuch's heart is like the hem of his skirt, it is floating.

Almost all the people in the Godman's Workshop saw this magical scene, the Godman drove a strange car with two wheels, carrying a palace eunuch speeding down the main street in the Fang; There was no horse-drawn cart, and no one pushed it; The speed is surprisingly fast, almost comparable to a galloping horse. The car does not make a sound when it walks, but it can make its own beeping sound when there is someone in front of it; The end is magical. For a long time, this matter became the talk of sergeants and craftsmen.

However, these are not things that Ye Jinyu will pay attention to, his eyes are on gunpowder.

Gunpowder is not so easy to get, although it is easy to say on paper, but it is still troublesome to actually get started;

Fortunately, Ye Jinyu is standing on the shoulders of giants, the direction is not wrong, and the raw materials for gunpowder are ready-made; After several times of weighing, proportioning, stirring, blending; With the help of a sergeant, gunpowder in its primary form was quickly formed.

Even according to the introduction on the information, I got some egg whites to try to granulate the gunpowder, but this has a drying process, which takes longer, and the finished product will not be visible for a while and a half.

Next, it was time to test the gunpowder.
