"Dango, you're finally awake." Ye Tan heard Tuanzi's words, and said happily.

"Uh-huh, I'm awake, I'm awake." Tuanzi happily circled in Ye Tan's mind, it gained a lot of energy, and condensed a lot, I believe that in the near future, it will be able to conjure up an entity and come out to walk: "Xiaotan, take a look, the system is more beneficial after the upgrade." ”

"Well, I'm watching." Ye Tan found that after the system was upgraded this time, it was very different from before.

Tuanzi excitedly chatted to Ye Tan: "Xiaotan, now you can sign in fifteen times a day, and now that the system has been upgraded to level three, you have a chance to find a mysterious sign-in point, and you can check out mysterious items when the time comes." ”

"Great!" Ye Tan said as he looked at the current sign-in interface carefully, the interface of Tianjing has not changed, but now the level of the system has become level three, and the points next to it also show ten thousand one hundred and eighty points.

The biggest change is the lottery interface.

The original lottery interface has doubled in size, and the bottom of the lottery interface shows "65", which is the remaining lottery number of Ye Tan before the upgrade, although the system has now been upgraded to level three, but the lottery number has not changed, and Ye Tan can continue to draw at any time.

And the part that has become bigger is an exchange interface, Ye Tan swiped the void with his hand, the exchange interface can be slided, most of the things are covered by a layer of faint mist, and now there are only two things that can be clearly displayed, one is Jin Xuantie, and the other is Yun Jingjin.

And what is used to redeem these two things is not points or money, but food, and at least food that has reached a high level of proficiency.

Ye Tan looked at the exchange interface, blinked his eyes, and asked Tuanzi: "Tuanzi, is it serious to exchange food for gold Xuantie and Yunjing gold?" ”

To be honest, it is not too difficult for Ye Tan to come up with food that has reached advanced proficiency, a long time ago, Amu had already brushed Northeast cuisine to an intermediate proficiency level, and now the advanced proficiency level has also reached seventy percent, and it won't be long before she can come up with dishes with advanced proficiency at least this piece of Northeast cuisine.

And the golden dark iron and the cloud essence gold......

That's the material used to make a spaceship!

Such a high-grade material, exchanging it for food?

This......

Did she take advantage of it?

Tuanzi said, "Xiaotan, don't be surprised, this is normal. ”

Now that the energy has recovered a lot, a lot of Tuanzi's data has also been recovered, so Tuanzi answered Ye Tan's question very smoothly: "This Jin Xuantie and Yun Jing Jin are both products of the Huanji Galaxy, such as this Yun Jingjin, I told you, is a product of the Qingyan Planet, and the Jin Xuantie is a product of the Black Gold Planet, and the Qingyan Planet and the Black Gold Planet are in the Huanji Galaxy, which belong to the mineral planet." ”

"Mineral Planet?" Ye Tan remembered the sci-fi movies he watched in his previous life and all kinds of descriptions of the future mecha era, so he said: "The people around the Ji galaxy can build spaceships, so these mineral planets are equivalent to their mines?" ”

Good boy!

How many mines are there on a planet?

Ye Tan couldn't imagine it.

It's no wonder that these Golden Dark Iron and Cloud Essence Gold are incomparably precious and rare in her eyes, but in the eyes of those people in the Ring Ji Galaxy, they are commonplace.

"Yes!" Tuanzi replied: "Moreover, there are many of these mineral planets in the Huanji Galaxy, especially very many, not only gold and dark iron and cloud essence gold, but also many, many kinds of ores, in addition to making spaceships, it can also make weapons, it is the kind of weapon that you can't imagine, the most powerful, a single cannonball can turn a planet into a death star." ”

Ye Tan listened, she shuddered, she thought of Lan Xing's backwardness now, if those people discovered the existence of Lan Xing, then Lan Xing would really have no power to fight back.

Sensing Ye Tan's emotions, Tuanzi hurriedly said: "Xiao Tan, you don't have to be nervous, Blue Star's current civilization level is too low, they can't detect it at all, so as long as you Blue Star don't take the initiative to touch those civilization levels, it will be very safe." ”

Ye Tan: ......

No, she knew that Tuanzi was comforting her, but why did she feel so heartbroken⊙▽⊙

"Of course." Tuanzi said again: "I came to Blue Star unintentionally, maybe it was an opportunity for Blue Star, but it also depends on the attitude of those in power in your Blue Star, didn't you ever plan to hand over Jin Xuantie and Yun Jingjin at an opportunity?" If that's the case, maybe you can win at the starting line, even if one day in the future, your Blue Star is really discovered by those higher civilization levels, you won't rush to the battle and have no power to fight back. ”

Ye Tan listened to Tuanzi's words, then nodded, maybe it was really as Tuanzi said, Tuanzi came to Lanxing, it was an opportunity for Lanxing, maybe it was also an opportunity for Lanxing's development, taking advantage of not being noticed, using these things obtained from higher civilizations, to arm himself first.

"Alright, let's get down to business." Tuanzi continued: "The ores produced in these mineral planets can allow the people of the Huanji galaxy to create a higher civilization, but in the same way, because there are too many such mineral planets in the Huanji galaxy, there is a kind of abnormal correlation between them, and this association affects the water and soil of other planets in the Huanji galaxy to a certain extent, making it difficult to grow things in those planets, so most of them live on nutrient solutions. ”

"So, food is very precious to those people." Ye Tan said.

"That's right." Tuanzi smiled and said, "So, you can understand why these delicacies can be exchanged for these ores." ”

Ye Tan nodded, thought about it, and asked another question: "However, if I exchange these ores with food, will those advanced civilizations discover the existence of the Blue Star because of this?" ”

This must be asked, she doesn't want to be a sinner of Blue Star.

"No, it won't." Tuanzi said affirmatively: "Xiao Tan, don't worry, the cosmic check-in system will block the blue star, and no one will know the location and existence of the blue star because of this, for them, the delicacies you exchanged for the past are generated by the cosmic energy, and they can't know the source at all." ”

Ye Tan breathed a sigh of relief when he heard this: "That's good." ”

After that, Ye Tan looked at the other exchange items on the exchange page that were shrouded in mist, and said with some excitement: "I don't know what the other things are." ”

Tuanzi smiled and said: "Then you work hard to save points, every time you save 5,000 points, a new exchange item will be refreshed, you have to continue to work hard, and when you reach 100,000 points, the system can continue to upgrade." ”

"Okay." Ye Tan responded confidently, and looked at the sixty-five lottery opportunities, she jumped up with a rub, and quietly went out of the door to Shuoxin's house.

Lottery go, lottery go.

She's going to hold Shuoxin for a lottery today! (End of chapter)
