After the rainstorm, the island finally cleared, and there was not a single white cloud in the sky.

The bright sunlight shone on the pond and the water droplets, shining a translucent, crystalline glow.

Chen Zhe walked to the window of the tree house, stretched slightly, looked at the sunny weather outside, and smiled: "While the sun is shining today, let's go out for a walk, there are still many places nearby that we haven't been to, and I don't know what interesting plants are waiting for us." ”

Hearing Chen Zhe's proposal, Da Qiao was very much in favor of it.

Da Qiao didn't go out when she picked chicken fir mushrooms before, but stayed in the camp to watch her family, and the continuous rain in the past few days really made her uncomfortable, and she had long wanted to go out to let the wind and breathe.

However, Xiao Qiao and Yan'er were still suffering from hangovers, and neither of them had the energy to go out.

"Brother Xiao Chen, I'...... I can't do it anymore, I still have a headache......" Yan'er pinched her head and said, "You guys go out, I'll stay in the camp to guard the house." ”

Xiao Qiao also echoed: "I will also accompany Yan'er to stay at home, I am dizzy now, and it is not suitable to go out." ”

Hearing the resignation of the two girls, Chen Zhe was not reluctant.

After all, two people go out and two people stay behind, which is a very suitable combination.

"Then you two will stay in the tree house to rest, and Mengyun and I will go out for a walk. Chen Zhe said.

"Okay, stay safe. Yan'er admonished.

With all the equipment, Chen Zhe and Da Qiao left the camp and set off, the direction of the hot spring and the direction of the chicken fir fungus Chen Zhe had already explored, this time he and Da Qiao walked in a new direction.

After the rainstorm, the hillside is muddy everywhere, and the road under your feet is naturally not easy to walk.

After sobering up, Da Qiao regained his shy and shy appearance, and even if he was gently held by Chen Zhe, he would blush and heartbeat.

Seeing this scene, Chen Zhe couldn't help but laugh in his heart, as if the woman who was drunk yesterday was not Da Qiao.

The two of them kept walking, and after about a mile or two from the camp, they entered another forest, which was completely different from the banyan forest where Chen Zhe and the others lived, and the tall trees in front of them were a completely new species.

These trees have straight trunks and sloping branches, and their leaves are oval, with a vibrant green appearance.

As soon as Da Qiao saw this kind of tree, she couldn't help but be attracted by its upright appearance, and she asked curiously: "Chen Zhe, what kind of tree is this, do you know it?"

In fact, she just asked casually, because she didn't think that Chen Zhe could know all the species of trees, after all, the variety of plants on this tropical island was too rich, if not tens of thousands, there were thousands of species, could Chen Zhe know every plant?

Unexpectedly, Chen Zhe really recognized it, and this tree was not difficult for him.

His gaze lingered on the trunk for a brief moment, and the system automatically recognized the name of the tree.

[Item detected: A mature and tall tung tree.] 】

"This is the oil tung tree. Chen Zhe smiled and said, "You can tell from its gray bark and shiny leaves." ”

"I see. ”

Da Qiao nodded without doubt, she believed what Chen Zhe said.

However, this also made her admire Chen Zhe even more, and said sincerely: "Chen Zhe, you are really amazing, you actually know so many plants." ”

"Haha......" Chen Zhe scratched the back of his head embarrassedly, after all, this is an achievement achieved by relying on the system.

"It's just because I'm more interested in plants. He explained with a smile.

And at the same time.

In the live broadcast room of Wilderness Survival.

Today's host, He Chen, was also shocked by Chen Zhe's understanding of plants.

He tilted his head and asked Mr. Kong, a botanical expert next to him, "Hello Mr. Kong, is Chen Zhe's judgment correct? Is the plant in front of them really a tung tree?"

Teacher Kong smiled and nodded, "Chen Zhe is right, this tall tree is the tree of the Euphorbiaceae family, the oil tung tree.

This tree prefers moist, hot weather, so it is very common in the tropics, and it has some distinctive characteristics, such as a thicker trunk, a more upright and straight trunk.

In addition, its leaves are oval and shimmer with oil, so it is easy to distinguish. ”

"I see. ”

He Chen nodded lightly, and then said,

"But to my surprise, Chen Zhe seems to know all kinds of plants, and it has been more than two months since he came to the island, and in these two months, Chen Zhe has seen a large number of plants...... It was as if he knew every plant. ”

This is actually not difficult for Chen Zhe at all, because every time he encounters a plant system upgrade system, it will be automatically recognized, but in the eyes of others, this is already a very remarkable achievement.

How much knowledge does it have to be to know every plant you encounter?

Even Mr. Kong, an expert in botany, couldn't help but say with admiration: "That's right, I've actually been watching it since the first episode of the show, Chen Zhe's knowledge is very profound, sometimes some plants even I have to check the information to call their names, but I didn't expect Chen Zhe to be able to say it accurately......

Chen Zhe's knowledge reserve is unbelievable. ”

He Chen also nodded: "Yes." ”

While the two were talking, Chen Zhe suddenly walked under a thick tung tree and kicked down the trunk of the tung tree.

Boom ——!

With Chen Zhe's earth-shattering kick, the oil tung tree began to shake violently.

Da Qiao was stunned for a while, and asked curiously, "Chen Zhe, why are you ...... Suddenly ravage this tree?"

Chen Zhe didn't rush to answer, but raised his foot and kicked it towards the tung tree again.

Boom ——!

The thick trunk of the tree shook violently under Chen Zhe's attack, and then some spherical objects on the tree fell down with a flutter.

Da Qiao walked over to take a look, and saw that they were some spherical fruits, about five or six centimeters in diameter, and covered with a layer of wrinkled skin, which should be the fruits of the tung tree.

It suddenly dawned on her that Chen Zhe was kicking the tree to pick the fruit.

Because the trunk of the tung tree is too straight and the branches are too far from the ground, it is not cost-effective to climb up and pick them.

She bent down to pick up a fruit, peeled off the outer skin, and asked, "Chen Zhe, is the fruit of the tung tree edible?"

Unexpectedly, Chen Zhe immediately shook his head and said: "Don't eat it, the fruit of the tung tree is poisonous, and if you eat it, something will happen." ”

"Ah......h

Chen Zhe didn't answer her question immediately, but said with a smile: "You'll know when you go back, because I'm not sure if I can succeed yet, so I can't answer your question for the time being." ”

Da Qiao pouted a little depressed when he heard this, and said dissatisfiedly: "Hmph, sell Guanzi again." ”

......

The two of them tossed in the woods for more than two hours, until they were sweating profusely.

A large basket of tung tree fruit has accumulated in the bamboo basket, and these fruits have given off this strange smell when they are wet by the rain.

It's not fresh, but it's not bad either, it's just the smell of plants, a bit like freshly peeled bark.

Chen Zhe carried the full rattan basket on his back and returned to the camp with Da Qiao.

Seeing this, He Chen, the host in the live broadcast room, couldn't help but ask curiously: "Teacher Kong, I have the same problem as Da Qiao, since the fruit of the tung tree is poisonous, why did Chen Zhe pick a lot of fruits and go back?"

What was his purpose in doing so?

Although Chen Zhe deliberately didn't tell us, can you answer for us?"

Teacher Kong smiled, nodded and said, "Of course." In fact, the answer to this question is not difficult, and the name of the tung tree has already answered us.

The reason why the tung oil tree is called tung oil is because its fruit contains a lot of oil, and the fruit of this tree can be used to extract oil. ”

"Squeeze oil?" He Chen said, "Squeeze vegetable oil?" It seems that Chen Zhe is planning to make some fried and fried dishes?"

"No, no, no......"

Teacher Kong immediately shook his head with a smile and said,

"Teacher He, you misunderstood, the oil refined from the fruit of the tung tree is toxic and inedible, it can only be an industrial oil, so Chen Zhe will definitely not use these oils to stir-fry. ”

"Oh?"

When He Chen heard this, he was a little confused,

"Since you can't stir-fry, what does Chen Zhe do with this oil?"

I don't know about this, but Chen Zhe himself has to reveal the answer. Teacher Kong said.

In a blink of an eye, Chen Zhe and Da Qiao returned to the camp with a basket full of fruits from the tung tree, and Xiao Qiao and Yan'er, who were standing on the tree house, saw it from a distance and immediately greeted them.

"Brother Xiao Chen, have you found anything good?" Yan'er asked impatiently.

Xiao Qiao drooled as he looked at the fruit in the bamboo basket, and said with a smile: "Isn't it delicious......?" These little fruits look delicious!"

Da Qiao hurriedly stopped his greedy cat sister and said seriously: "Silly girl, don't talk nonsense, these fruits are poisonous." ”

"Hah, poisonous?" Xiao Qiao was stunned for a moment, and then couldn't help asking, "If it's poisonous, why do you have to pick it back? Do you want to refine poison?"

Although the little girl's brain hole is a little big, Da Qiao feels that what she said actually makes some sense.

"Is it going to be used to refine poison?" Da Qiao asked Chen Zhe worriedly.

Chen Zhe shook his head and smiled: "Of course not, the poison is still more effective than the poison of the poison dart frog, and the poisonous effect of these fruits is not enough." ”

"Okay......" Da Qiao saw that Chen Zhe didn't mean to answer, so he didn't insist on asking any more.

Chen Zhe turned back to Yan'er and said, "Yan'er, help me boil some water in a casserole, and then cook the fruits of these tung trees...... Remember, don't overcook, just boil the water for another five or six minutes. ”

"Understood. Yan'er nodded obediently and immediately followed Chen Zhe's instructions.

But when doing things, the little girl always had doubts in her heart - what did Chen Zhe want to do here?

Chen Zhe didn't rush to answer everyone's questions, but first went to the neighborhood to find some bamboo and came back.

Splitting the stout bamboo lengthwise and splitting the bamboo into strips is one of the most basic tools, which is used to weave rattan baskets or make other tools.

This time, Chen Zhe wanted to use bamboo strips to create a different tool, he put several bamboo strips together and then formed a circle to make a circle with a diameter of about 80 centimeters, and there was a storage space in the middle of the hoop to fill objects in.

Chen Zhe made seven or eight such hoops in one go, and after they were done, he went to the neighborhood to cut some wood and came back.

One of the thick trunks is made directly into a stake, while others are split into thinner sticks to form a rectangular wooden frame......

By the time this series of processes was completed, Yan'er had already cooked and dried all the fruits of the tung tree.

Chen Zhe walked over with a hoop made of bamboo strips, and stuffed the fruits of the ripe tung tree into the hoop one by one, and soon the hoop was filled with fruits, showing a state similar to "tea cake".

The only difference is that the tea cake is filled with tea leaves, but Chen Zhe's cake is filled with the fruit of the oil tung tree.

Seeing this, Yan'er had roughly understood Chen Zhe's intentions, and then looked back at the handmade wooden stakes and wooden frames not far away, and Yan'er asked in a low voice: "Brother Xiao Chen, I understand, do you want to squeeze oil?"

"Oil extraction?"

Da Qiao and Xiao Qiao looked blankly at the cake stuffed with tung tree fruit in Chen Zhe's hand, they really couldn't associate this kind of thing with oil.

Hearing that Yan'er guessed the correct answer, Chen Zhe smiled and admitted: "That's right, I do plan to extract oil, this is the ancient method of oil extraction, and the fruit of the tung tree is the raw material for oil extraction."

However, the efficiency of the ancient method of oil extraction is not high, and the difficulty is also very large, I am worried that I will not be able to squeeze it myself, so I have not told you before. ”

"Chen Zhe, is this how humble you are, is there anything you can't do?" Xiao Qiao teased with a smile.

Yan'er also said encouragingly: "That's right, Brother Xiao Chen, I believe you can definitely do it." ”

"Then I will borrow your good words. Chen Zhe said with a smile.

After that, six "oil cakes" have been made.

He carried the "oil cakes" to a wooden shelf next to them, and then stacked them together in a cylindrical shape, and placed a clay pot under the wooden shelf, so that once the fruit of the oil tung tree was forced out of the oil, the oil would drip directly into the clay pot.

After setting up these "oil cakes" stuffed from the fruits of the oil tung tree, Chen Zhe waved the wooden stake in his hand and smashed it down towards the "oil cake".

Boom ——!

There was a heavy muffled thud, but nothing happened......
