[Congratulations to the host for completing the novice mission: saving the plants in the garden. It took 27 days, and the plant survival rate was 88% (greater than 80%), which was considered qualified.
Please check the task panel to receive the reward. 】
At the end of June, with three days left before the deadline, Ye Han finally heard the news that the task was completed.
It was like the bell for the end of a long exam suddenly rang in his ears. Ye Han's long-tensed nerves completely relaxed at this moment. He raised his hand to block the increasingly dazzling sunlight above his head and suddenly felt a little dizzy.
She immediately found a shady place to sit down, holding onto the tree trunk, breathing rapidly and trying to calm her rapid heartbeat.
No matter how calm he appears, Ye Han is just a college student who has just graduated.
Nanshan Botanical Garden has been abandoned for a long time. There are various things that need to be planned, a bunch of complicated affairs that need to be handled, and many technical things that need to be learned... Anyone would feel stressed.
What's more, there is a 30-day mission deadline as a requirement.
It's like the sword of Damocles hanging over your head all the time, and you never know when it will fall.
Fortunately, after so many days of hard work, Ye Han finally completed the task before the countdown ended.
When her rapid breathing gradually returned to normal and her violently beating heart gradually returned to normal, the girl stood up and quietly looked at the surrounding scenery.
Looking around, the previously desolate botanical garden has completely changed. The roads are clean and tidy, the lake is sparkling, and the rescued trees are trimmed neatly, showing a vitality that has never been seen before.
Even though there are pressures and difficulties in the process of completing the task, the sense of accomplishment that comes from achieving the goal is equally indescribable.
It was a huge spiritual satisfaction, as if the blood in his body was boiling - Ye Han had never truly felt the meaning and value of his existence like he did now.
The plants here need her more than her real family members.
This strong feeling of being needed is particularly fascinating.
The sunlight shines through the shade of the trees onto Ye Han's body, like dancing gold foil; her almond-shaped eyes reflect the green silhouettes of the plants, as clear as washed water; the smile on her lips is without any haze, just like her heart at the moment, bright and joyful.
After a while, a translucent interface appeared before my eyes:
[It is detected that the novice task has been completed, and a novice gift pack will be issued: plant nutrient solution*1, water purifier*1. 】
Ye Han clicked on the two sparkling icons to receive them, and he couldn't help but feel a little more excited.
After receiving it, a translucent bottle and a small round ball soon appeared on the stone platform next to it.
The bottle is about the size of a mineral water bottle and is filled with light green liquid, which is in a semi-solid state. Under the sunlight, it looks like flowing amber and is very beautiful.
Ye Han guessed that this should be plant nutrient solution.
The other ball is only the size of a one-yuan coin, pure white, and there is nothing special about it from the outside.
"...Is this the water purifier?" Ye Han thought, picking it up from the stone platform.
It was quite heavy and had a very smooth surface. It fell into her palm. It was so small that it could easily roll off if she wasn't careful.
Ye Han thought of the huge aeration purification device installed by the water treatment company in the middle of the lake, and then looked at the small one in his hand. He couldn't help but doubt: Can such a small volume really purify tens of thousands of tons of water?
No matter how you look at it, it seems impossible.
With this question in mind, Ye Han took it and walked onto the water promenade, all the way to the center of the lake.
The wooden fence was repaired some time ago. The paint has dried, leaving only a faint smell, which is blown slowly into the air by the hot summer wind and can rarely be smelled.
Looking down along the railing, although the lake water has not yet reached the standard water quality, it is visibly no longer turbid, with only a small amount of particulate matter and suspended matter floating in the water. I believe that these will gradually be eliminated in the water circulation in a few months.
Ye Han tightly grasped the coin-sized ball in his hand, and felt his palms were sweaty and slippery.
Afraid of losing it, she immediately stretched her clenched right fist over the railing, then took a deep breath and let go.
The next second, the white sphere fell into the water in free fall, accompanied by a soft "plop" sound, splashing small water droplets, and layers of ripples spread along the center. After sinking for a distance, the white ball just... disappeared.
?
Ye Han held on to the railing tightly with both hands and looked down. His eyes scanned the water surface where ripples appeared several times, but he did not see any trace of it.
Did it sink to the bottom of the water, or did it turn into some chemical substance and degrade in the lake water?
Or... did it rely on the water flow and its own speed to go to other places in the lake?
But these cannot achieve long-term purification——
Ye Han clearly remembered that the water purifier could be used permanently.
Just as she was making all kinds of guesses, her eyes suddenly flickered.
At that moment, she seemed to see a giant transparent net laid in the water, and there was more than one layer of it, densely packed extending all the way to the other side of the lake, with no end as far as the eye could see.
Looking again, the huge net that "covered the sky and the sun" disappeared again, as if the scene just now was just an illusion.
Ye Han's heartbeat quickened, and he stared at the lake without blinking until his eyes became sore. Only then did he see the illusory 'giant net' again under the refraction of light.
It is composed of many layers of mesh "silk threads" interwoven with each other. It is very dense and transparent in color, almost blending into the lake water. It is like an ancient giant beast lurking at the bottom of the water, occupying the entire lake surface with countless dancing tentacles, which makes people can't help but gasp.
Yet it seems to have no shape, as the gaps and density between the grids are constantly changing with the flow rate of the water, sometimes expanding and sometimes contracting, blending itself perfectly into the water without affecting the survival of any living thing.
At the same time, it also has extremely strong filtering and decomposition capabilities.
Ye Han saw with his own eyes some suspended matter floating in the water approaching rapidly like a moth to a flame, but disappearing the moment it touched it. It should have been decomposed into smaller molecules or other microscopic particles in a very short period of time, which could not be observed with the naked eye.
The whole process was magical and shocking.
From a small ball to the 'giant net' covering the entire lake, to the incredible purification ability, all of this is beyond the imagination of ordinary people.
Just as Ye Han was immersed in the "miracle" displayed by future technology, the looming "giant net" slowly disappeared into the lake, like a phantom, and no trace of it could be found anymore.
Ye Han came to his senses belatedly, raised his hand to block the glaring sunlight, and closed his eyes feeling a little uncomfortable.
The long eyelashes intertwined and closed, and when they opened again, small black spots appeared on the retina, which might be the sequelae of staring at the shimmering lake for too long.
After standing here for a long time, Ye Han felt that he had been baked into a shriveled fish by the scorching sun, and even his hair seemed to smell burnt.
She walked quickly towards the pavilion and sat on a stone bench in a dark place. Only then did she finally feel a hint of coolness in the hot summer.
The system's voice sounded: "Host, the water purifier has started to operate. The host can check the water quality status on the product's initial interface. It is currently in intelligent self-purification mode. If you want to set it yourself, please enter the parameters manually."
Ye Han clicked on the light screen and saw the three-dimensional model of the artificial lake in the product details.
It is as detailed as a miniature artificial lake. Whether it is the water corridor, the distribution, quantity, growth status of plants in the lake, or the data of the water body, all are clearly visible; and the disappearing "giant net" is also clearly displayed in the picture, floating with the water flow.
The lit spots of light represent that it is constantly purifying the entire water area, and as it operates, the corresponding parameters are constantly changing.

The water quality will be improved within 24 hours and will be maintained above 95 points for a long time.
The monitoring data is real-time and highly accurate, with accuracy reaching dozens of decimal places. All the filtering, decomposition, monitoring and calculation are achieved by just a small sphere. The technology of the future is truly amazing.
Ye Han turned and looked at the artificial lake. The calm water surface concealed everything. If it weren't for the data on the light screen that was still jumping, it would have seemed like a bizarre dream.
The effect of the water purifier allowed her to get a glimpse of the magnificent corner of Galaxy Technology. At this time, Ye Han looked at the glittering nutrient solution on the stone table and felt great expectations for it.
She clearly remembers the function of plant nutrient solution: to stimulate cell activity, promote rapid growth of plants, and make them full of vitality.
This is good news for the plants that have just been rescued. It can maximize their survival ability and also give them some time, so that they may be able to bloom beautiful flowers in the summer.
Instructions for use:
Please dilute this product with water at a ratio of no less than 1:100 million. After the first use, the concentration can be appropriately reduced according to the needs of the plants to avoid waste.
She read the sentence silently twice to confirm that the ratio was 1:100 million.
In other words, 1 ml of nutrient solution must be dissolved in at least 100 tons of water to achieve this dilution ratio, which is conservatively estimated to be enough to water thousands of trees.
There are not so many plants in the entire Nanshan Botanical Garden.
Moreover, Ye Han roughly calculated that the nutrients contained in 1 ml of liquid are simply astronomical (equivalent to 2-3 tons of compound fertilizer), and they also have to meet the nutritional needs of plants of different types, different growth cycles, and different habits...
This is incredible.
Just like plants use nitrogen fertilizer to grow leaves, phosphorus fertilizer to bloom and bear fruit, and potassium fertilizer to take root... Different fertilizers are used in different stages, and each plant has different preferences. Excessive fertilization can also cause seedling burn.
But there is only one bottle of nutrient solution, how can it meet the needs of different plants?
Ye Han stared at the light green liquid in his hand for a while, then quickly became relieved and stood up with it.
Why think so much? As long as it is useful, that’s enough.
Ye Han clenched the high-tech product with his slender white fingers, preparing to try it out in the evening.
