After living on a desert island, they all plotted evil against me.

Zhang Liu's mouth was full of smiles.

Put the piece of taro in your hand into your mouth and chew it.

Then he also started to pick up a piece of bracken with chopsticks as a match.

The roasted taro was still a bit dry after all.

But the interaction between Zhang Liu and Anya made the other girls who were about to set off look slightly strange.

Noticing this, Zhou Fang tilted her head and glanced at Zhang Liu.

There was some hesitation in her heart.

That is whether you want to help the other party deal with the current situation.

Chapter 4 There must be no embarrassing situation where the size is too big to fit in.

While Zhou Fang was struggling, Xiang Wanying also noticed something was wrong with the team atmosphere.

Licking her lips slightly, she spoke directly: "Ruoyan, can we bring a wolfsbane spurge to poison the fish this time?"

He held a tender white palm core in his hand and chewed it in small mouths.

Xiang Wanying also suddenly asked.

She would ask this because she came here to change the subject and warm up the atmosphere.

Secondly, I really have this idea.

After all, the other party said before that Wolfsbane Euphorbia could be used to control pests.

So from another perspective, can it be used to poison fish?

After all, Xiang Wanying also saw Qin Ruoyan poison a freshwater fish to death with this before.

"No, Wolfsbane Euphorbia is a chemical mixture of toxicity. It will not evaporate and disappear casually."

Shaking her head, Qin Ruoyan rejected the suggestion.

Then she whispered Li Dongyuan's Liu Chen Ge as a case study:

"Panellinium tangerine peel, tangerine peel, pinellia, ephedra, wolfberry and Wuyu."

"The six kinds of medicine should be aged for a long time, and they will work wonders when used as medicine."

Except for Song Shuyao, who was thoughtful, everyone else looked at him with confused expressions.

Qin Ruoyan, who understood that everyone did not understand, continued to explain: "The wolfsbane in this ballad refers to the wolfsbane spurge. The meaning of this Liuchen song is that the longer the Chinese medicine of these six subjects is used, the more toxic the medicine will be. Tough.'

"Ok."

After hearing such a detailed explanation, Xiang Wanying also understood that she had indeed thought too much.

A helpless sigh.

Then she said: "It seems that if you want to catch some sea fish, you can only choose fishing or spearfishing."

"When there is relatively mature boat technology in the future, let's go fishing offshore." They took turns picking up five pieces of roasted taro and passing them to Qin Ruoyan, Xiang Wanying, Gu Xixi, Lan Yueting, Su Yan, and then Zhang Liu Xiang Wanying, who took the taro and bit off half of it, smiled and said, "If you want to eat from the sea, you have to have some skills."

"Ah."

Nodding, Xiang Wanying, who received the taro, gently raised the corners of her mouth while swallowing the taro in her mouth.

The other four girls around her had the same expression.

Although not said.

But they actually had some taste just now. Anya fed them, but she didn't.

But now... everyone is even!

After lunch.

Anya set off with her team.

Qin Ruoyan and others also carried an extra metal-tipped bamboo spear about one and a half meters long as self-defense.

There have been cases where Anya was injured after being attacked by a wild boar, so everyone is extremely concerned about safety protection.

At the same time, Qin Ruoyan also wrapped a wolfsbane spurge in a banana leaf and took it away.

In her words, although this thing cannot be used to poison fish, if there is a sudden battle, it is also a good choice to use it to quench poison on arrows or blades.

..............................

Standing outside the bamboo house with Zhang Liu, they watched Anya and others disappear under the cover of trees.

Then Zhou Fang gently held the opponent's palm and said, "Zhang Liu, let's go back and rest. You should be very tired this morning."　

"Sister, please go to bed first. I'll go to Bamboo House No. [-] to continue burning some charcoal." Zhang Liu scratched his head and said to Zhou Fang next to him: "By the way, I'll sit down and rest there."

"Then...shall I accompany you?" Zhou Fang gently grasped her left arm with her right hand and whispered after thinking for a while.

As she spoke, not only was her voice hesitant, but her face gradually turned red.

A thought flashed through Zhou Fang's mind at this moment.

That is, the other girls are now sleeping and resting in Bamboo House No. [-].

If you and Zhang Liu were alone together in Bamboo House No. [-], might something happen?

Licking her lips, she didn't dare to think about how she would give up her bottom line at Zhang Liu's request...

"It's very hot over there. Sister, you'd better not come over here and sweat. You'll smell." Zhang Liu was completely unaware of Zhou Fang's implication and shook his head gently to reject the other party's suggestion.

Then he said: "Sister, you'd better go to Bamboo House No. [-]."

Zhang Liu stopped mid-sentence.

Because he noticed Zhou Fang's blushing cheeks and suggestive eyes.

He reached out to grab the other person who subconsciously moved back due to eye contact, and then Zhang Liu said, "Sister, why don't we go make charcoal together?"

"What you said sounds strange to me..." Zhou Fang tried hard to suppress the rising corners of her mouth, and murmured in a low voice.

But then she leaned over and pecked Zhang Liu gently on the cheek.

"This is the first lesson I'm going to teach you about the relationship between men and women." Moving her lips away from her sweetheart's cheek, Zhou Fang said playfully in her ear: "Before she married a girl home, she said You gave a hint, but if you don’t understand it, you’ll have to wait for the next opportunity!”

After speaking, Zhang Liu didn't wait for an answer.

She turned around and trotted to the door of Bamboo House No. [-].

Watch this scene.

Zhang Liu, who had already imagined all kinds of bad thoughts in his mind, was dumbfounded.

He never expected that the other party would do something like this.

"Huh huh huh!" Standing at the doorway of the bamboo hut with a bad woman's smile, Zhou Fang turned around and walked into the bamboo hut, then lay down on an empty bed.

Before walking in, she also smelled her armpits by raising her arms.

no smell...

A certain class teacher quietly breathed a sigh of relief.

I stared at the door of Bamboo House No. [-] for a long time.

Finally, Zhang Liu walked to Bamboo House No. [-].

Make a fire, then drop small twigs to expand the fire.

Then put in the middle piece of wood and lay it. The top layer is a large piece of wood that may not be carbonized by high temperature.

After all this is done, close the lid of the kiln.

The preparatory work for burning charcoal has been completed, and all that remains is to wait.

Then Zhang Liu sat on the extremely dry ground of Bamboo House No. [-].

　There was no rest. At this moment, he was preparing to make the "human blower".

PS·Blower drawing.

[img=1141,1147]https://rss.sfacg.com/web/novel/images/UploadPic/2023/07/3c7772af-e8c8-45f9-9370-d9ae5929184f.jpg[/img]

In order to ensure that the air outlet of the blower will not be "too big to fit in".

Zhang Liu casually picked up a piece of wood as thick as his arm and ran to the newly built brick kiln for comparison.

The prediction in his eyes was perfect.

This piece of wood can fit right into the air inlet of the iron-making furnace.

As such.

As long as the air outlet of the blower is about the same thickness as the wood.

Once you have the control object, the subsequent production is quite simple.

In Bamboo House No. [-], there was originally a paste-like mud pit used for kneading bricks.

Although after a morning of use, the mud pit that was originally filled by everyone has been used up.

But the remaining ones are pretty much the same when used to rub a blower casing.

Oval casing, front opening.

Holding the bamboo piece in his hand, Zhang Liu kept using it to press the space inside the blower.

He could ignore the bumps on the outside, but the inside had to be smooth and there should be no bends.

Otherwise, the blades will be rubbed and the air outlet efficiency will be affected...

Chapter 4 is not as convenient as taking medicine!

After the blower is roughly shaped.

Zhang Liu carefully lifted it and placed it on the top of the earthen kiln next to him.

As the "smoldering" in the earthen kiln intensified.

The color of the entire earthen kiln roof began to change from gray to white at the edges.

After this blower housing is placed on top.

Although there was no immediate "squeaking" sound of water being drained.

But after a few minutes, the entire Bamboo House No. [-] was filled with a "smell of clear water and earth"

Apparently the water in it is being evaporated out at an accelerated rate.

After finishing the main body, the next thing he had to rectify was naturally the wind blades inside.

Regarding the material of the wind blades.

Zhang Liu also thought about it a lot.

At the beginning, the principle of "sturdiness and durability" was followed.

He planned to use metal pieces as wind blades.

After all, the weight of alloy sheets produced by modern technology is just considered.

In fact, it is about the same weight as the wood that can be used to make wind blades.

It’s not because the alloy sheets are so high-tech that they are actually less dense than wood.

It's because the wood pieces want to rotate and resist centrifugal force.

A certain thickness is bound to be required.

The alloy sheet is due to its superior toughness.

On the contrary, a relatively thin piece can be put into a usable state.

After this one ebbs and flows.

Naturally, the weight of the alloy sheet is relatively light.

But Zhang Liu later took the concept of "stability" into consideration.

Alloy blades are indeed lighter than wood blades.
