On the fifth day, the little seedling grew twenty centimeters, and the wind blew and swayed, but it never broke.

On the ninth day, the seedlings were about forty centimeters tall and as thick as ordinary sugar cane, and they grew firmly in the sand, and the fierce wind could not blow them.

On the sixteenth day, it can no longer be called a small seedling. The saplings stumbled upwards like bamboo, and after a few days of work, they suddenly grew about 50 centimeters. The diameter has become thicker, about six centimeters, and the outer skin is a deep purplish-black color, which looks like a small black pillar from a distance.

Its roots seem to be deeper. Not to mention the strong wind, the officers and soldiers of the garrison tried it, and the three strong men came together, but they couldn't shake it.

Xia Baocheng guessed that its root system should be many meters deep underground.

……

Just like this day by day, Xia Baocheng watched this plant, which only had one pole, growing and getting thicker and thicker. In the arid desert where no grass grows, there is no water to irrigate, and it still grows vigorously.

When they reach the height of a person, their growth slows down.

At this time, their rods were almost as thick as Xia Baocheng's thighs.

The main trunk stopped growing, but at the top, several small branches were divided.

These twigs, the same color as the main trunk, are purple and black, and the texture is like steel, whether they are shaken or twisted, they do not move at all.

Such a strange plant, without a single leaf.

If it hadn't grown up, Xia Baocheng would have directly regarded it as an ordinary colored cement pillar.

When these small branches growing on the tree grew to about seventy or eighty centimeters, Xia Baocheng saw a strange growth phenomenon of this plant.

Overnight, the branches on these trunks stretched out a dark black membrane like a black umbrella.

These umbrella-like membranes overlap each other, forming a large circular ball at the top of the tree's trunk.

In addition to the color, it looks very similar to the round ball lollipop that Xia Baocheng's granddaughter loves to eat.

A stick with a large ball on top.

Three giant black lollipops, standing firmly in the long yellow sand, blending into the sea of sand, no matter how violent the northwest wind and sand, no matter how fierce the scorching sun, it will not affect its existence.

When Xia Baocheng saw the black ball on the tree for the first time, he thought it was the soldier guarding the three trees, so he made a black cloth and wrapped the tree.

It wasn't until I got closer, touched the surface of the black ball with forty or fifty degrees Celsius, and listened to the explanation of the squad leader on duty that I knew that the growth of this tree was so strange.

The spherical black film is probably the leaves of this strange tree. Xia Baocheng guessed.

During the day, when the sun is strong, the surface of these films remains at more than 50 degrees Celsius for a long time, and the hand feels warm, like a hand warmer.

On a cold night when the wind is howling, the temperature of the film also plummets, which can freeze people's hands numbly.

Xia Baocheng has been patrolling the mountains for decades and planting trees all his life, but it is the first time he has seen such a strange tree species.

I really don't know what it will look like when it blossoms and bears fruit in the future.

On this day, Xia Baocheng carried some mountain goods picked on the mountain, and walked around to see the trees.

When I walked to Tianming Valley, I found that it was much more lively than before.

In the place where the three strange trees were planted, a group of strangers were around, dressed casually, old and young, and at first glance they were not soldiers. They appear to have tools in hand, ready to break open the black film of a tree.

There are also people, with tools, digging into the surrounding land, as if to carry out some kind of surveying work.

Xia Baocheng looked a little anxious, blinked his eyes a few times, put his toes on tiptoe, stepped on the liberation shoes, and ran over there.

But this time, before he could get closer, he was stopped.

"This uncle, this is a national-level experimental planting area, please don't come close. A young man with a ****** stopped him.

"Eh, I, I'm ......" Xia Baocheng rarely communicates with people on weekdays, and when he met this young man who was polite and polite, he seemed to be a scholar at a glance, and suddenly his words were a little knotted, and his hands subconsciously gestured a few times, but he didn't know how to explain.

Fortunately, squad leader Liang, who was on duty on the side, spoke out to relieve him.

"Researcher Gao, this is an employee of Senhua Forest Farm, a guide sent to us by the Forest Farm, who is very familiar with the environment in this area, and is also an old party member and a trustworthy person. ”

Squad Leader Liang's words explained the reason why Xia Baocheng appeared here.

The bespectacled young man's face relaxed, and he nodded and did not stop the old man any longer.

Xia Baocheng can walk around here from time to time, and it is also approved. The officers and soldiers stationed in the area need the help of a local, and Xia Baocheng, who grew up here, is the best candidate.

When Xia Baocheng approached the place where the strange tree was planted, the black film of a strange tree had been torn open.

A middle-aged man with sleeves rolled up and gloves poked his head into the torn membrane.

Looking at the big broken hole, Xia Baocheng felt silently distressed in his heart. Probably watching these three strange trees grow, he was a little disgusted that they were destroyed.

However, he couldn't speak at this time, so he could only stare intently.

"There you have it!" The middle-aged man spoke in Mandarin, and his muffled voice came out from the gaps, and he could hear his joy and excitement.

Xia Baocheng didn't blink, staring at the man who had drilled a hole, holding an earthy yellow ball about the size of a melon in his hand.

"In the same planting time, the varnish fruit grown here is three times larger than the Beijing city base, and twice as large as the southern one. The middle-aged man was overflowing with joy, and handed the fruit in his hand, which he called the varnished fruit to an old man with gray hair beside him, "Old Xie, look at this weight, the growth is gratifying!"

Xia Baocheng pondered the name, and finally knew what this strange tree was called.

He really didn't expect that this kind of tree would grow so fast, and it would have grown such a big fruit in less than three months after it was planted.

These people seem to have come specifically for this fruit, maybe it can be edible, but isn't that able to turn this wasteland into fertile land?

Xia Baocheng had a lot of ideas, and the idea that the fruit could be used as food was rejected by him after seeing those people use machines to cut the earthy yellow fruit.

The small cutter roars, and the powder of the fruit shell flies up, cutting a small incision, and then following this incision, a shiny, transparent liquid flows out.

Xia Baocheng grows in the northwest where water is scarce and is very sensitive to liquids. Seeing the liquid flow out, it was like seeing gold.

Can this tree hold water?

Xia Baocheng's heart was beating wildly.

The wind blowing in this place can take away the blood from the body, and there is still so much water in the fruit of this tree?

He guessed wrong, the tree was not producing water, but plant fuel.

"Yes, two hundred and twenty milliliters, and the amount of oil is also very high. ”

"It's so tall, it's the highest of many experimental planting sites, and it seems that this place is very suitable for the growth of varnish trees. ”

"Professor Zou, how many varnish fruits are there?" the gray-haired old man asked the middle-aged man who had just drilled into the black film.

"I just counted, eleven, very good. I'm now taking a couple of students over for a fuel test. ”
