Cheng Xi is a solid-eyed child.

Since the other party is so polite, then she will also accept it politely.

But you can't take advantage of people.

Resolutely do not do it.

"This is a return gift, a first-order crystal nucleus purification liquid."

Cheng Xi took out a small transparent box from the space, and 10 test tubes filled with purification liquid were placed inside, shining faintly blue in the sunlight.

Zhou Chen didn't expect to help and get a gift, and this gift was worth a thousand gold.

The whole person was stunned.

"No, no, no, we can't ask for it, it's too precious!"

Since the development of the purification liquid, the Central China base has been selling to the outside world, 60 crystal nuclei can buy five milliliters of first-order purification liquid, and at this price, the box is worth 1200 crystal nuclei.

It's too expensive, it's really too expensive.

That's enough for their team to hunt zombies for a week.

"Little sister, let's take it back, we're just doing us a favor."

"Yes, yes, it's a convenient thing, we can't afford this return gift~"

Everyone said no, don't, but the little eyes that looked at the purification liquid were full of longing, pitiful, and reluctant.

Although, the bottom line of being a man cannot be lost!

Several people swallowed a few mouthfuls of spit, trying to take their eyes off the transparent box.

Zhou Chen's heart was also dripping blood...... This thing is not only expensive, but the important thing is that the base has just started to be implemented, even if there is a crystal nucleus, you can't buy it.

Even extended the profession of the scalper!

Cheng Xi: "......"

If you take in the harazi that is about to flow out, I will almost believe it.

She twitched the corner of her mouth, "We're now a third-order ability, and the first-order purification liquid doesn't work, are you sure you don't want these gifts in return?" ”

What?

Third Order?!

Zhou Chen gasped, his eyes glaring like copper bells.

"You, you, you, you're already third-order?"

Longevity, they are all superpowers, why is there such a big difference?

They only knew that the little brother and sister were powerful, and the ordinary ability was not an opponent at all, but they had never thought about it in the direction of the third order.

You must know that Xu Qingzhou, the most prestigious Xu team in the Central China base, has just been promoted to the second order.

At present, the combined second-order abilities of the entire base do not add up to one slap.

It's scary!

"If you want it, we will accept this gift!"

Since this thing is not important to the young lady, fool (?) Don't.

A must!

Zhou Chen hurriedly took the transparent box, held it in his arms like a treasure, and smirked.

Cheng Xi saw that he had accepted the return gift, and finally felt at ease and put the third-order ability plant crystal nucleus he had collected into the space.

In the distance, Shen Xingluo was staring at a big tree and observing.

"What are you looking at?"

"Have you ever wondered why they progress so quickly?"

“......”

Good question.

Cheng Xi pondered for a moment, followed Shen Xingluo's gaze, and found that the soil on the ground seemed to have traces of turning.

"What do you think of?"

"Zombies."

Shen Xingluo squatted down, and the Tang knife had already been inserted into the turned soil, "All the zombies in the botanical garden are missing, maybe it's the handiwork of these plants." ”

As soon as the words fell, a dusty cloth was turned out of the soil.

Underneath the fabric is a white arm with green tendons.

"It's a zombie!"

Two powerful people worked together to uproot the big tree, revealing the dense zombies below, and there were more than 20 corpses in this area.

"Plants can swing rattans after mutation, and they will bind up zombies and swallow them, digesting zombie crystal nuclei for upgrades."

Although Shen Xingluo was guessing, he was not far from ten.

"Maybe mutant plants are more difficult to deal with than zombies themselves."

This is not good news.

Mutant plants are rising too fast, and they will not only have to guard against zombies in the future, but also against the ubiquitous mutant plants.

】

Especially plants that are stout in their own right.

"Fortunately, the Central China base is built in the Great Plains."

Although the Star Jewel Resort is used for vacation, it mainly relies on cultural facilities to attract tourists, rather than natural landscapes.

"No fool would build a base on a mountain, would he?"

Cheng Xi just said it casually, but Zhou Chen and the others, who were stunned for the nth time, showed frightened eyes.

She: "? ”

I don't know why, but I have a bad premonition.

***

Thanks to the existence of the miniature bomb, which can be called an artifact, the remaining greenhouses are much easier to solve.

The group worked together and soon came to the last place.

After Cheng Xi had nearly a million interstellar coins, he had harvested countless supernatural plant crystal nuclei, of which the second-order had the most, and the first-order and third-order were in the minority.

And Zhou Chen and the others kept burying their heads in picking up money (crossed out) to pick up crystal nuclei, and finally received a return gift of 50 tubes of purification liquid from Cheng Xi.

They all laughed like they were silly.

"I'm stupid, it's a great harvest today!"

"Dafa, I've never been so rich in my life......"

"With these purification liquid upgrades, we have also dug up the crystal nuclei of a lot of ability plants before!"

"This is the first of its kind in Central China!"

"It's developed, it's developed, and the plant crystal nuclei are all wood-based, so we can leave some points to upgrade wood-based abilities."

"Everything else will be replaced with supplies, I'm going to the Star Supermarket for big shopping!"

"Eat it for a week spicy crayfish!"

When everyone was celebrating the harvest, Shen Xingluo, the only one on the scene who was not hot-headed, had already found the location of the nutrient soil.

"Here."

The Botanical Garden's nutrient soil stocks are beyond imagination.

At a glance, there are four large warehouses, each of which is piled up.

The two parties quickly discussed how to distribute it - in fact, Zhou Chen's six-person team only had a 50-square-meter space ability, and there was not much to put at all.

Even if there are two big trucks outside.

Shen Xingluo stood in place after the other party was full, and with a wave of his hand, all the nutrient soil disappeared.

"Wow-"

"Damn, is this what I can see?"

"The third-order spatial powerhouse is so strong!

！ ”

Zhou Chen mistakenly thought that it was because of the spatial ability, so he didn't think about it at all, but this didn't prevent them from casting a worshipful gaze on Shen Xingluo.

One by one, they became star eyes again, but this time the other party changed from Cheng Xi to another person.

Shen Xingluo: "......"

Although I have felt a lot of admiration and admiration in my past and present lives, it is the first time I have encountered such an emotional outlet.

You modern people are really different.

Mission accomplished, return the same way.

When everyone stood at the entrance of the botanical garden again, they met Chen Lian and the others with gloomy faces again, and to everyone's surprise, they were even more embarrassed than yesterday.

The dusty tracksuits were now in tatters, and some were even hanging like rags.

I just can't see it.

"Poof—"

Zhou Chen was the first to laugh.
