A shining stone, Tang Ankang didn't know what it was. Two dollars cost five thousand credits, and he had never heard of such a luxury when he was so old.

"Sister, what the hell is this?" Tang Ankang only dared to look at it, but didn't dare to really reach out and touch it.

"It's energy stone, and it's a high-quality energy stone."

Tang Anxin said as he cut off a stone the size of an egg and a small piece the size of his thumb. Tang Ankang's eyes were straight, what did her sister do just now? It looks like something was used to chop up the stone, that's 5,000 credits!

"Sister, what is this thing for?"

"Energy stone is the source of energy for each planet, and it is also the associated ore of many minerals, which have been taken away by the Interstellar Alliance before, these two pieces are considered fish to slip through the net, what is the use...... Mainly as the energy of the laser wood bin. Tang Anxin said as he carefully put the energy stone into the laser wooden warehouse he assembled.

"This is a laser wooden barn...... Sister, it's a crime for you to do this! "Tang Ankang is stupid, is her sister so bold, why didn't she see it before?

[Encouragement with you]: It's so high-tech, this wooden warehouse looks very greasy!

[lulu]: The anchor is so bold, and he gives a wave of rewards to suppress himself.

Tang Anxin didn't expect that he could also receive a reward by getting a laser wooden warehouse, and the system's laughter echoed in his mind, just because the points at this moment finally broke through the 1,000 mark.

"I assembled it myself, and I didn't buy it in the underground market, nor did I steal it, and I didn't circulate it from the arsenal, so how can it be considered a crime?" Tang Anxin said seriously.

Tang Ankang: Is this the point of "......"? Just assemble it yourself? (⊙o⊙)… It seems that no one has ever said no.

"This is just for your self-defense." Tang Anxin folded the small laser wooden warehouse in his hand directly and turned it into half a palm-sized, which looked very exquisite, and it could be used as an ornament when wearing a chain around his neck.

"Sister, is this really a laser wooden warehouse? I saw that the uniformed star policemen were holding arms in their hands. As a boy, Donnakang still likes to pay attention to these things, and his friends have talked about them in private.

"Those are too backward to carry, this is an improved version, but it's a pity that the materials don't come together, otherwise I can make a smaller one." Tang Anxin felt a little regretful, and Tang Ankang felt that his sister was going to heaven.

"You can't take this out easily for self-defense, otherwise it's easy to get into trouble. In addition, it is a healing ointment. Tang Ankang said and gave Tang Ankang five bottles of low-level healing ointment.

"Sister, why do you still have so much! I don't need it, let's sell it for credit! ”

Tang Ankang said pitifully, holding the five bottles of ointment in his arms and not knowing where to put his hand, this is 30,000 credits, and someone may not be able to earn so many credits in a lifetime.

"You can keep it for you, I still have a lot of this here. If anyone asks about this ointment, they will say that you bought it from the underground market. ”

Tang Ankang suddenly felt very suspicious, could it be that my sister sold this healing medicine to the underground market just to ...... Let them take the blame?

"Sister, aren't you afraid that the underground market will make trouble for us?" Tang Ankang asked with some concern.

Tang Anxin looked at his straight-eyed younger brother and said patiently: "Ankang, now the attitude of each planet towards the supernatural is not clear, do you want your sister to be captured?" Want me to have my fingernails cut for study? ”

Tang Ankang shook his head in horror, naturally he was unwilling, and they wouldn't be so gentle and only cut their fingernails for research, right?

"So we have to be careful, although it is not good to buy things in the underground market, it is not illegal. If I don't sell them the ointment, you'll be in trouble with the ointment and the laser barn. And the underground market will not trouble us because of this, they also make money, as long as there are interests, everything is easy to say. ”

When Tang Anxin analyzed Tang Ankang like this, he realized that he had thought too little before, his sister was obviously only one year older than him, but she was much more mature than him.

"Sister, I know, I must not tell anyone, Brother Roger doesn't dare to tell! Sister, you said that my strength suddenly increased, is it also because of the ability? ”

Tang Anxin: "......", the worried child, has only reacted now.

"No, it's because I gave you a potion to drink, which can make your strength greater, otherwise how could you enter the Martial Arts Academy! Hum! Now that I think about it, Tang Anxin still feels congested, and she actually made a mistake.

Tang Ankang: "......" his sister really cares for him.

Tang Ankang left with a heart full of gratitude, and Tang Anxin took out another laser wooden warehouse, which was white, which was exactly the color she liked. From the beginning of looking for parts, she has found two handfuls, and she can't just care about herself and ignore her stupid and cute brother.

"Master, your system needs you. When you're away, the system feels so pitiful and lonely. "The system is starting to be cute.

"Speak human words." Tang Anxin looked at the laser wooden warehouse in his palm and felt that it was very suitable for her to use.

"Master, the points have reached the upper limit of upgrades." The system hurriedly said seriously.

"Oh."

"Master, why do you always have such a one-word conversation with the lovely system, why are you so cruel!" The system has a feeling that it is about to collapse, and such an owner is really terrible compared to the young lady of the system next door.

"What's in it for me after upgrading?" Tang Anxin asked this question, and the system crashed.

"Master, we'll disappear without upgrading, do you remember?"

"I'm only a teenager now, and it seems like it's been a long time before I'm gone." Tang Anxin was not moved at all, and he had to be cautious when dealing with this system.

"Well, after the master system is upgraded, it can provide you with intermediate quenching fluid and intermediate healing medicine." The system immediately understood that only enough benefits were the driving force for Tang Anxin's upgrade, and Tang Ankang was the person Tang Anxin cared about the most.

"What about the other than that?" Tang Anxin was a little moved, now that the low-level quenching fluid was ineffective against Tang Ankang, she really needed the intermediate level.

"In addition, more live planes can be opened, previously there were only Earth Stars, but now you can search for planes of the same level as Earth Stars." The system said excitedly, more viewers represent more rewards and points.

"Equivalent plane? How many planes are there in your system that are on the same level as the Earth? Tang Anxin was obviously more curious about this.

"So far, it seems like there are about sixteen." The system replied tremblingly, not knowing what else this master would ask.

"Then the question is, how many planes are higher or lower than the Earth Star level?" Tang Anxin tapped her fingers on her desk, her heart was not calm at all, she felt that her eyes had been opened.

"Master, this system has no right to inform you."

"You mean, you don't want to level up." Tang Anxin said solemnly.

System: "......" found such an owner, and it was so pitiful, so pitiful.

"Master, listen to me, although we can only open more dimensional live broadcasts after upgrading to level 2, but if we upgrade to level 3, then we will be able to open the plane trading system. When the time comes, you'll know how many planes there are in our main system, and you'll be able to buy things from other planes, such as products of higher civilizations! ”

The system also fought hard in order to upgrade, which was the part it couldn't tell Tang Anxin, but it still told the other party euphemistically. At this moment, Tang Anxin felt that his eyes lit up, and being able to buy the products of the advanced civilization plane sounded very attractive.
