Since it is a prepared crossing and not an emergency, of course you must be fully prepared. Zheng Lang took a moment to think about how to get He's Bi. Of course, it is not possible to come hard, and the predecessors who are hung up are a lesson from the past, and I don't know if the seniors will be quiet when they die.

Zheng Lang's idea is a dignified exchange.

How can an emperor willingly take out a jade seal in exchange? There are too many ways for a modern person. After a few days of preparation, the carry-on warehouse was filled with all kinds of supplies.

After working for a few years, Zheng Lang can be regarded as having a small amount of savings, but this time he took them all out and replaced them with all kinds of things that may be used, as for what will he do in the future? Please, brother is going to the Tang Dynasty, and you can sell any souvenirs as antiques over there.

The people regard food as the sky, and food is always the most impressive to the emperor of a feudal empire. Potatoes, sweet potatoes, cotton, wheat and other seeds, as well as supporting planting techniques, unfortunately the seeds that can be bought by hybrid rice are actually sterilized, can not be used to cultivate the second generation, can only be used once.

Next is the technology that can improve productivity, cement, paper, steel and other copycat technologies that can be found on the Internet, and I actually found a copy of "Traveler's Essential Copycat Technology Summary", good thing, thanks to the boring otaku.

Again, Zheng Lang prepared a complete set of textbooks from primary school to high school, which depends on which emperor he meets and whether he has the foresight to see the importance of education.

"Well, bring this with you, as a final killer." Zheng Lang said and closed the "History of the Tang Dynasty" in his hand, and said to the black cat sitting on the sofa watching TV: "Nine thousand, think about it again, what else can be exchanged, I always feel that the chips are not enough." ”

Jiuqiansui strongly objected to Zheng Lang calling him Jiuqian, so the two sides compromised with each other and omitted a word, which was regarded as a concession for each and called the black cat "Jiuqian".

Jiuqian usually acts in the form of a black cat, and occasionally there are snacks that can't be reached, and when you need to open the door, you will become a cat-eared lady form. Although dressed as a maid, this maid never does housework. The maid costume on her body is more like it grows out than it is put on, and it can't be taken off at all.

By the way, Zheng Lang's master bedroom has also changed hands.

Animal World is being shown on TV, and this episode is about fish under the sea. The black cat couldn't take his eyes off it: "How do I know, I'm just an artificial intelligence, and I'm not good at dealing with these things that need to be improvised." That's why I'm looking for you to work with you. Are you ready, okay we're leaving. ”

According to the black cat, although he can now teleport in space, due to the damage of the equipment, he cannot achieve accurate positioning, and can only lock the approximate location. After teleporting, the two were sure that they could appear near Chang'an, around the front of the Tang Dynasty. However, it is impossible to determine what year it is, and it is impossible to determine the exact location. Therefore, Zheng Lang may appear in peacetime, or it may be just in time for a military disaster. Chang'an in the Tang Dynasty often had people rebelling or something.

"You are also a product of high civilization, so there is really nothing you can use to defend yourself? Just give me some Iron Man armor and Devil Fruits. "As a small citizen, Zheng Lang can only get the highest-end weapon in a few days than the watermelon knife bought at the vegetable market at the door. But then again, even if he had a watermelon knife in his hand, he really wanted to give him a neck to cut, and he couldn't do it. The neck that was hurt the most by him in this life is the duck neck......

The black cat sat down with its paws spread: "Not really for the time being, but if this mission can be successful, you can have no problem if you want a Gundam." Now the only one who can keep you safe is me. When I'm with you, I can block out the perception of the people around me, and I still have a little bit of mental power, but I can't output more than a hundred kilograms. If there is something you really do, you can try to delay it as much as possible, and the space teleportation ability only needs 24 hours of cooldown to activate again. By the way, the gun is for you, the last one, and it's almost out of power......"

Zheng Lang silently took over the only weapon left by this powerful civilization and put it into his personal space.

After thinking about it, I really can't think of anything else to prepare. Zheng Lang sat on the sofa to calm down.

Of course, it is a lie to say that I am not nervous, a little excited, but also quite a little scared. After all, he is going to a world that he has only seen in books, and the restoration of him in film and television works is just the imagination of future generations. Zheng Lang took a deep breath and stood up with sunglasses for pretending: "Brave boy, you're going to create a miracle, let's go, nine thousand." ”

Before leaving, Zheng Lang tidied up his hairstyle in the dressing mirror and said with satisfaction: "Tsk, if you put the facts aside, you are really handsome." "Open the door and go downstairs.

"Where are you going? Where to? Nine thousand said.

"Go to the Tang Dynasty." According to Zheng Lang's thoughts, no matter how high-end things like spatial teleportation, they need to find a square, after the lightning and thunder, and the wind blows, a black hole sucks him in. A moment later, he appeared in the Tang Dynasty squatting with his legs in his hands.

"Where does it take so much trouble?" The black cat began to popularize all kinds of common sense to Zheng Lang again: "What is the easiest way for us to move an object from point A to point B?" ”

"I know this, it's to fold the space, and the two points coincide with each other, which is what science fiction often calls wormhole jumping!" Zheng Lang was proud, feeling that he didn't lose the face of the earthlings this time, although we couldn't do it, but we thought of it, send the question!

"It's not." The black cat continued to "popularize science", and his eyes were full of his usual disdain: "Remember what I said about the theory of consulting information?" Every object that exists is defined by various information. This information of course includes information about the spatial coordinates of the object. Then we want to move an object to another space-time, and the easiest way is to directly modify the space-time coordinates of this object. For example, if you are at home and I change your coordinates to be in the supermarket, then you will immediately appear in the supermarket. ”

Isn't this too unscientific, or should I say it's too scientific? What's the difference between this and using cheat to modify the game directly, is this something that can be applied to reality?

"Well, can you change my height information?" Zheng Lang asked with a twinkle in his eyes, in fact, he was thinking about other sizes.

"I can't do this for the time being, I only have the relevant equipment for space-time coordinates now, and I can't do precise positioning, and even in Di Wenming, it is forbidden to manipulate genes and souls, let's go."

Saying that, the black cat's paw clicked the remote control, turned off the TV, and the animal world was just finished. The black cat jumped on Zheng Lang's shoulder on its own, and the blue gathered in a pair of blue eyes, getting deeper and deeper, and finally the blue light flashed, and one person and one cat disappeared in place.
