But fortunately, at present, Wanpea Mountain can be used as a supercomputer, so Qingxue began to learn from the human services trade agreement, and put forward countless questions, such as the unification of measurement units, the question of budget and final accounts, product nominal size standards, and so on.

When he was the big leader of Taoyuan Star, he signed various agreements that remembered his name!

Then they all used the paper made by Qingxue and Lin 2frog to write and print, although it was hard but there was no way, who told them to want to start a trade exchange with King Nehod, but also afraid that the paper matter would be exposed!

Although this large set of operations was to replace the dangerous paper, but at the same time, it made King Nehod sick. King Nihod himself did not like to come, and sent a representative named Homs to deal with the negotiation of the terms of trade.

The two sides traded for about 2 months, and many industrial products greatly enhanced the function of Pea Mountain, and also improved the living conditions of Qingxue and Lin 2 frogs. King Nihod's ability to rebuild the entire system of science and industry is truly beyond his reach. If Lin 2 Frog hadn't been afraid that his life would be in danger, he would have wanted to see how he had arranged this skill tree for the restart of civilization. Which one to get first, then which one and so on. If at the beginning, what they never forgot was to return to Taoyuan Star or return to Earth, now they are happy.

And after receiving the signal that they had agreed on privately by the three 2 frogs, they didn't reply to the letter. And the judgment of Lin 2 frog is that maybe there is more than 1 Kerr black hole in the pathway! In other words, although there are two days that still occur frequently, not every time the sun is the same star!

It wasn't until the third month, that is, the third time, that Lin 2 Frog was contacted again. Of course, this time it's not a code word for a full-spectrum signal. It is their specific blue light 445 wavelength frequency based on the ordinary communication encryption.

Lin 2 Frog found that the contact was actually Guang Linde! And he received the signal during the expedition of Proxima Centauri, although he did not participate in the private discussion of the 3 2 frogs, but he also replied with such a code!

And Lin 2 Frog's first message was to ask: "How do you know the code words that our 3 2 frogs agreed upon with each other?" ”

And Guang Linde replied: "Because it was discussed with Guang Zhixin and Guang Kars." ”

In other words, although it is not 3 2 frogs, but as a light person, it is the same 3 people, and the conclusion is that it coincides.

Because of the limited time, the two-day phenomenon didn't occur for a long time! Lin 2 Frog quickly sent a large section of the content written in advance.

And Guanglinde needs to wait for the next time such a launch window appears, that is, 3 months before it can be restored.

In the process of trading, Holmes made a proposal that Qingxue and Lin 2 Frogs would crusade against the evil beasts. Rat Rao reluctantly stepped into the territory of the beasts, and was often attacked by the beasts, and King Nihod was to pay a handsome reward.

Qingxue really coveted those returns, so she agreed. There's a soundcannon, anyway! And laser weapons! No beast is a problem.

Lin 2 frogs and Qingxue pushed a cart of laser cannons by themselves. Although the size of the laser emitter is not large, the size and weight of the charging components such as battery capacitors required are still not high, and they are equipped with 2 sets of batteries and one car.

They and their laser cannon truck arrived at the designated location to take a look!

Oh my! It's a beast, it's a beast, but they don't, it's a beast in groups! That's a big bunch! Of course, if this is 1 or 2, it will be solved casually, and the problem is such a big group.

They saw something much like the first mammal on Earth, the Didont. They are the same, if not estimated, and live in groups, guarding a huge shrub steppe as a territory for food and perch. And this territory is really too large, and just look at the abundant vegetation to know that any modern person wants to cultivate their mood.

That's it, I can't deal with it!

Qingxue and Lin 2 frogs are 30 centimeters tall, and for rat people, they are big, but for these two-toothed beasts, which are close to 2 meters tall and weigh 9 tons, Qingxue and Lin 2 frogs are like two frogs staring at elephants.

Qingxue scratched her head and said, "They should be quite friendly!" ”

Lin 2 frog nodded and said, "If you don't infringe on them, it should be." But we are here to violate them. ”

Qingxue said: "We estimate that we can kill 2!" So will the others rush over to avenge them? ”

Lin 2 frog shook his head and said, "I don't want to gamble, especially when the bet is life." ”

Qingxue thought for a while and said, "Generally speaking, this kind of grassland herbivore should be migratory. Why don't we call King Nihod to wait a few months? ”

Lin 2 frog: "If you don't wait a few months, they will migrate away by themselves, and we will go, how many months of effort have we put in to twist them away?" ”

Qingxue said: "Isn't this a little... ”

Lin 2 frog nodded and said, "Well, although he is shameless, we still have to have a bottom line." ”

"Well, the main thing is that you can't hide it." Qingxue moved the corner of her eye, and Lin 2 frog looked in that direction, and there were a few grasses on the hills in between that were shaking abnormally, probably because the nezumi scouts sent by King Nihod were secretly monitoring the two of them.

"There's no hurry now, let's take a look at their habits today." Lin 2 Frog suggested. So they began to investigate the life of the two-toothed beasts here.

However, the more you walk, the wider the shrub steppe, and more diplodonts.

They did occupy a large amount of land.

"Actually, I'm thinking, maybe there was a similar thing on the earth, that is, ancient humans needed land for development, so they set fire to the entire grassland to dispose of these giant beasts in batches!" Lin 2 frog said with some fear.

"Actually, if you want to deal with them, you may really have to do that!" Qingxue also frowned.

Lin 2 Frog sighed, "But modern humans definitely won't do this. ”

Qingxue said: "But maybe this is a necessary step to enter the modern era?" King Nihod is about to take this step now! If the two of us can't complete the task of driving them away. I guess the next thing he's going to do is set it on fire! ”

"So we have to think of something! How to deal with them? Let them move early? Lin 2 frog said.

Qingxue shook her head and said, "No, even if they are allowed to migrate early this year, they will come back next year, and then they may face a strong castle and a rat slaughter." The nezumi can't deal with them yet, but their manufacturing level is changing with each passing day, and it will be difficult next year. Even if it is not a large area of arson, there are weapons against them! ”

Lin 2 frogs were thinking about it on the one hand, and on the other hand, they felt sorry for these giant beasts.
