"Little girl, are you too vigilant?"

Liu Zhiquan shook his head amusedly, rinsed the bag in his hand, handed it to Luo Chen, and said, "Keep your little food for yourself, otherwise sooner or later there will be a time for you to cry." But seeing that Luo Chen was still a little hesitant, he squatted down and pulled Luo Chen's hand and put the bag in her hand, "No one in the camp will use this thing, so you can rest assured to take it, when it is the first time I saw the commemoration of the Zerg, Bai Xuxiao still has the body tissue of the Zerg they met for the first time in their home."

What's more, when mining, I can always encounter a few octopus arthropods, and I still have a few in the space, so this one is not bad. ”

However, no one in the camp can use the bag, which does not mean that no one in the mine or the city will use it, and even if this material containing energy is not used for weaving, it is also a very good choice to repair combat uniforms like her.

Luo Chen pursed her lips and looked at the bag in her hand, if she couldn't see such obvious kindness, she would have lived in vain for so many years.

So before Liu Zhiquan withdrew his hand, she took out an energy recovery agent and stuffed it into his hand and said, "This is what I gave you." ”

"This is the energy recovery agent" Liu Zhiquan looked at the medicine in his hand suspiciously, not that he didn't know it, but he was a little incredulous, they went out this time in the nature of an outing, so they didn't bring much medicine, and now there are not many energy recovery agents and healing potions left.

Bai Xuxiao, who was chasing Luo Chen, was also shocked, the pouch was of little use to them, the main thing was that no one would use it, and the energy restorative was different, it was something that could save lives at a critical time, Luo Chen actually sent the energy restorative out because of a pouch.

"Yes, energy restorer." Luo Chen nodded affirmatively, the demand for items is different, there are still a lot of potions in her backpack, and because they were made before the system upgrade, the details of the materials required for the potions have not been cleared due to the system update, and she has already seen a lot of medicinal materials on the way here just now.

Liu Zhiquan glanced at Luo Chen with a complicated look in his eyes and said, "Thank you, I can't refuse this potion, it's too important for us now." ”

"Hmm." Luo Chen smiled and nodded, and then asked, "Do you want more?"

"You still have" Liu Zhiquan's brows, which seemed to have not been unresolved for thousands of years, still did not change, but his eyes were round.

"Energy recovery potion, healing potion, and a drink that can restore physical strength, which one do you want" Luo Chen piled up a cute little face and tilted his head to look at Liu Zhiquan.

But Bai Xuxiao on the side felt a tingling scalp, and he had an ominous premonition.

"How much I will exchange with you" Liu Zhiquan didn't notice at all, the rule of exchanging things has become his subconscious behavior.

"This bag can be exchanged for two, ten for any one of the elixirs, and one for one physical strength drink." Luo Chen said as he drew up the contract, "First of all, if you still lack anything, tell me, and if so, I will add the exchange request to the contract." ”

Luo Chen's eyes lit up, and he passed the contract to the pen tablet so that Tutor Liu could view it.

The content of the contract is very small, after all, there are few things that can be exchanged, mainly emphasizing that the two parties who sign the contract after leaving here must not question the content of the contract in any form, let alone renege on it.

However, in addition to the exchange of potions, there is also one more content, that is, you can exchange two pieces of cloud crystal ore for food, Liu Zhiquan looked at Luo Chen puzzled, "What do you want so many cloud crystal mines for?"

"I want to see if I can absorb it." Luo Chen replied very seriously, after all, this is the truth.

Liu Zhiquan shook his head helplessly, when he first mined, many students had this idea, after all, he was guarding a cloud crystal vein, but when he came the second time, he gave up all of them, and the probability of absorption was too low.

He looked at the tablet and thought, "You wait for me." After saying that, he gathered the busy students together and handed the tablet to the students to pass it on.

Bai Xuxiao didn't go over, after all, he watched the entire transaction process, and he glared at Luo Chen with a look on his face at this time, which I know, and said, "Did you have a premeditated plan to carry so many materials to come here to approach us, what is the purpose" Luo Chen dared to list the contract so clearly, which can only show that she has a lot of materials on her.

Luo Chen gave him a roll of his eyes in disgust, "How is it possible, don't tell me that the space storm is teleported at a fixed point, and besides, who would run to this kind of place without a star network if nothing else, I'm more life-sparing, so I like to store things." ”

"The price of the medicine is not cheap, do you have so much money" Bai Xuxiao didn't believe what she said, just looking at her appearance as a wealth fan, she didn't look like a rich person.

"Who do you look down on, I can't do it myself." The little ghost is annoying, there are so many problems, it is a mutually beneficial thing, why bother too much, you see how good Tutor Liu is, he will organize everyone to exchange without asking.

However, Mentor Liu probably hoarded these materials as when she was on her last mission, after all, her information will no longer have any information after the end of this mission.

In fact, not only that, Liu Zhiquan even guessed that she was also on a mission before being teleported here by the space storm, so she had so many materials on her, and this exchange method Luo Chen was not a loss, she would give up after finding that she could not absorb the energy of the ore, and these cloud crystals could be exchanged for a lot of star coins after being brought out.

"It's more convincing to say you bought it than to say you made it yourself." Bai Xuxiao also rolled her eyes as Luo Chen looked, believe you are a ghost, the little girl is very bad.

Believe it or not, Luo Chen didn't bother to pay attention to him, and turned around and walked to the others.

"Really fake"

"You can exchange useless materials for potions"

"The marble mine can also change potions, mentor, you didn't lie, right?"

“”

Everyone expressed their doubts, how could there be such a good thing, guarding the cloud crystal vein to change the dressing agent, in addition to spending some physical strength, this is equivalent to picking it up in vain.

"You have also seen the contract, and the potion is provided by Luo Chen. Also, don't fool people with messy things, Luo Chen is young and doesn't know him, but I'm not a tutor. Liu Zhiquan looked at everyone sternly, these little ghosts had done a lot of tricks before.

Luo Chen took out a chair and put it in front of the table, then jumped on the table with his toes on the ground and shouted, "The students who need to exchange will sign the contract first, and then come to me to redeem it."

Everyone's heads turned to Luo Chen in unison, and then at the same time they looked back at Liu Zhiquan expectantly.

Liu Zhiquan nodded and signed his name on the contract on the pen tablet.
