Refusing Xie Linxing's request and washing away his exhaustion, Tang Jingyun lay on the bed, but he didn't feel sleepy.

Zhan Zhixue has never been able to contact him.

It's really hard to have a summer without air conditioning!

And the temperature is too high, and the products of the Snow Jade Golden Lotus series are not easy to preserve.

Although she can make simple saltpeter ice, it takes energy to turn it upside down.

I'm so busy right now, where do I have so much time to do this.

She knew that there would be a white crystal in the toilet or in the corner of the wall, and this thing was saltpeter.

Moreover, saltpeter is most commonly used to make black powder, fuses, glass, matches, fireworks, and is also used as fertilizer, which she will definitely need to make in the later stage.

But now, it's really not working.

So, she turned her mind to the other three dimensional plants.

Plants that can make the surrounding environment warm in winter and cool in summer, Tang Jingyun asked Ming Youli and Li Yu.

None of them on their side.

What Tang Jingyun needs is plants that can release cold or hot air.

And Ming You is away from them, and there are plants that can only grow in a certain environment.

For example, the fire-type magic elemental plants on their side.

It must be grown in a very hot environment!

The fire elements that the plants need are all drawn from this environment.

One is to release and the other is to absorb, and the difference is obvious.

Tang Jingyun sent a call to Zhan Zhixue again.

There are still only messages that go out for something.

Tang Jingyun hung up the call request, opened Zhan Zhixue's plant page, and had to find it slowly.

It's not easy to find.

Tang Jingyun typed in the keywords - "fire", "ice", "warm in winter and cool in summer", etc.

A whole bunch of plants come out every time.

Tang Jingyun was dazzled, but none of them were what she wanted.

Just when Tang Jingyun was about to get dizzy again, the system suddenly prompted Zhan Zhixue to send a call request.

Tang Jingyun sat up and quickly connected the conversation.

Seeing Ji Xuan in the video frame, he breathed a sigh of relief.

"You weren't there several times when I looked for you, but I finally appeared."

Zhan Zhixue had just finished her retreat, and when she opened the system, she saw a bunch of call requests.

Tang Jingyun was the least, but he contacted Tang Jingyun first.

Tang Jingyun's plane was originally taken to heart by Zhan Zhixue.

Ever since she discovered the Nine-Leaf Pure Heart Lotus here, she has been regarded by Zhan Zhixue as the most important relational plane.

This time, he advanced, which was easier and smoother than ever.

This is all thanks to the Pure Heart Grass that Tang Jingyun traded to him.

The snow-jade clothes are fluttering like butterflies, and they are clear and handsome when strolling.

The clothes are embroidered with large silver peonies, and the petals are layered on top of each other, revealing the elegance of masculinity, and the innate nobility and elegance are rendered more and more outstanding.

Zhan Zhixue's cuffs were raised, and the silver peony bloomed layer by layer, and said, "Are you looking for me to trade plants or do you have a newly discovered plant?"

Tang Jingyun glanced at the other party's surprisingly expensive clothes, and said with a smile: "Where are the new plants so easy to find?" ”

"It's me, I want a special plant, the kind that releases cold air when it's hot and hot air when it's cold, do you have one?"

Zhan Zhixue almost didn't think much about it, so she said a plant: "Half a foot and two flowers." ”

Tang Jingyun was overjoyed, "Really?" ”

Zhan Zhixue said: "Yes." ”

"The half-zhang two-sided flower, also known as the balance guardian tree, is a low-level spiritual wood, and some low-level monks will plant a half-zhang two-sided flower next to it when planting plants that need constant temperature."

The constant temperature here is very different from the constant temperature as Tang Jingyun understands.

The constant temperature that Tang Jingyun knows is to keep the temperature value constant by manual or automatic control methods, and the temperature value is not affected by other factors.

It also makes the initial set temperature the same or similar to the temperature at any given time.

And this constant temperature in Zhan Zhixue's eyes also has the meaning that the temperature is always the same.

However, the word "constant temperature" is understood separately, constant is eternal and unchanging, and temperature is warm temperature.

Half-zhang two-sided flower is a kind of spiritual wood that knows how to protect itself, it needs the environment within three zhang and nine meters of its own three zhang, and the temperature is like spring in all seasons.

It releases a colorless, odorless, and non-hazardous gas at all times.

This gas reacts strangely with the temperature, and when the ambient temperature is too low, this strange reaction will increase the ambient temperature.

When the temperature is too high, the surrounding temperature will be lowered.

In Zhan Zhixue's world, a person like him who is highly cultivated is no longer afraid of the cold.

All the time is like spring for them.

And some of them are not high in cultivation, and they are so poor that they can't even afford to buy low-level cultivators with thermostatic formations and thermostatic talismans.

In addition to using half-zhang two-sided flowers to assist in planting spiritual plants, most of the residential areas are indispensable for half-zhang two-sided flowers.

Of course, if the surrounding environment exceeds the limit temperature that can be adjusted by the half-foot two-sided flower, then it will not work.

Either it was killed by heat or froze to death, so it was a low-level spirit wood.

The half-zhang two-sided flower actually has no effect in the cultivation realm, but it is difficult to find a tree in the mortal realm.

If Tang Jingyun is a mortal on Zhan Zhixue's side, unless she has a monk in her family or has a lot of wealth, she can get a half-zhang two-sided flower.

But now, it will be much easier for Tang Jingyun to choose to trade with Zhan Zhixue.

Tang Jingyun thought for a moment and said, "I'll exchange the life plant with you." ”

Tang Jingyun also had three-color flowers and silver jade flowers in his hands, both of which Zhan Zhixue did not have.

However, Zhan Zhixue said: "Can you use the Nine-Leaf Pure Heart Lotus?" ”

Tang Jingyun hesitated.

She found three of the Nine Leaf Pure Heart Lotus before, gave Zhan Zhixue two plants, and now there is only one plant left.

If he gives it to Zhan Zhixue this time, he may not be able to find it here.
