Judging from the brief introduction given by the system, the pure spring water hyacinth not only has the function of purifying water quality, but also can effectively decompose heavy metal ions and organic pollutants in the water. Pen "Fun" Pavilion www.biquge.info

Ordinary water hyacinth has a big flaw. It can only absorb pollutants in the water, but these pollutants are still present in the plant after being absorbed by the water hyacinth. At present, the technical means in the world are difficult to separate and utilize the pollutants in ordinary water hyacinth.

Whether it is used as animal food or decayed and buried, these heavy metal toxic pesticides are difficult to separate from the water hyacinth itself.

In the process of filtering the water quality layer by layer, various pollutants are accumulated in different positions. Heavy metals accumulate in the stems of the gourd, organic pollutants accumulate at the bottom of the leaves, and toxin residues such as pesticides are absorbed by the flowers.

Although it is not known what the dark blue flowers do. But the purpose of the gourd stems and leaves is obvious. The gourd stems can be refined to produce highly pure metal substances, and the leaves can be used as natural fertilizers.

In addition to these advantages, the Pure Spring Hyacinth is a plant refined by breeders. It also means that it does not have any reproductive ability, although a seed can grow hundreds of square meters of space, but it does not have the terrifying ability of ordinary water hyacinth to expand wildly in a water-rich environment.

Lin Zeng put the seeds in the jade box and took them out again.

He needed to plant the seeds in five hours, otherwise the more than ten hours of refining work would be wasted.

Before leaving the breeding space, he glanced at the mission information on the wall.

The rest of the information has not changed, but at the end of the task, there is an additional progress prompt.

"Mission Progress: 1/3"

Lin Zeng clenched his fists excitedly, the first water source plant he refined, the Pure Spring Phoenix Eye Lotus, was recognized by the system.

He's one step closer to completing his mission.

Leaving the breeding space and looking at the time, it was already past six o'clock in the morning of the next day. The time he started refining yesterday was in the evening, and after thirteen hours of non-stop drawing, his physical strength reached its limit.

Lin Zeng decided that after planting the Pure Spring Phoenix-Eye Lotus, he immediately went to sleep thoroughly to refine the second water source plant and recuperate.

However, looking at the eleven Pure Spring Phoenix Eye Lotus seeds in his hand, Lin Zeng suddenly didn't know where to plant them.

Originally, there was a small pond in the nursery, but at this time, it was planted with sclerophyllous lotus, and there was no room for the growth of the pure spring water hyacinth.

After thinking about it for a while, Lin Zeng decided to soak the eleven seeds in a basin casually, and then find a suitable water surface to plant when he was free.

As long as it takes root and sprouts, it will be planted.

Lin Zeng asked the system and got a positive answer from the system.

After getting all that, Lin Zeng's upper and lower eyelids seemed to have never met in eight lifetimes, and they were crazy to stick together, relying solely on Lin Zeng's own willpower, it was difficult to separate them.

Lin Zeng fumbled back to the bedroom, threw himself on the bed, breathed heavily, and fell asleep with a snort.

After sleeping for a whole day and night, he continued to refine the other two water source plants.

One option is to use ordinary bowl lilies as the raw material.

For the last plant, Lin Zeng did not choose a complete aquatic plant, but chose a wild taro-like plant that can grow both amphibious and amphibious at the same time. It was on his way back to the nursery from Jianghua Farm, and he suddenly found on the side of the roadside mud that half of it grew in the mud and half on dry land.

"The seeds on the first star, the water bead lotus, are raised in the water tank, absorb a lot of water, bloom lotus, and store abundant water in the lotus petals, which can provide high-quality drinking water suitable for people. Each lotus petal can provide 200-300 ml of water. The dew taken out of the petals has a slight fragrance, and it is the best regardless of whether you make tea or brew wine. ”

"A star medium seed, a water-storing wild taro, the thick leaves can store a lot of water, and the developed rhizome locks the solid impurities in the water next to the rhizome. The water stored in the leaves can meet the standard of ordinary human drinking water. ”

After Lin Zeng finished refining the water storage wild taro seeds, the system's prompt sound sounded just right.

"Complete the 'Newborn Water Plant' quest. Water source plants are an extremely large category, which is the foundation of human activities from the land to the sea, please collect water essence at any time and refine a large number of water source plants. ”

Lin Zeng memorized the system's words.

The system prompt sound of the breeding space is actually very stereotyped, and many questions Lin Zeng does not ask, and it will not give prompts.

If it suddenly said something else, Lin Zeng would take special care to write it down, and often these contents were particularly important.

"Get the right to optimize a plant, and decide for yourself the plant variety you want to optimize. ”

Lin Zeng was very tired now, and he didn't want to use this opportunity hastily.

"Can you save this optimization opportunity for now?"

"Optimization opportunities can be saved, and the optimized plants are limited to the previously refined plant varieties, and the plants after the task is completed are not considered. "The system will tell him about the conditions under which the opportunity will be saved.

After completing the task, he slept very peacefully, and when he woke up, he didn't know how long he had been asleep, and compared the time, he found that twenty-seven days had passed since the start of the mission.

Lin Zeng stretched comfortably.

Twenty-seven days passed in a flash, and the later period was almost isolated from the world. Lin Zeng didn't know that in an unintentional moment, the plants cultivated by the inheritance from another dimension had brought subtle changes to this world.

Lin Zeng didn't have time to understand these things, he went downstairs and immediately looked at the red boy with a bucket on the first floor speechlessly.

Beside Hongzai, the basin that Lin Zeng threw into the eleven seeds of the Pure Spring Phoenix-Eye Lotus was completely covered by a bunch of green plants.

That's right, it's just a bunch, almost as high as Lin Zeng's shoulders, as tall as a mountain of plants, more like a matcha cone.

Well, I've been with Jiang Hua for a long time, and even my thinking is closer to foodies.

Hongzai poured a bucket of water on this pile of plants, and the wonderful thing is that a bucket of water poured down from the top of the plant mountain, and it did not penetrate much into the ground, and it was all absorbed by these plants piled up.

Lin Zeng only considered at that time that the Pure Spring Phoenix-eyed Lotus had tenacious vitality and was planted in a water basin for a period of time, so it was not a big problem. But he didn't take into account that the red boy would help him water, and the more he watered, the faster the Pure Spring Phoenix-eyed Lotus would grow, because there was not enough space, so he could only keep stacking them together and growing together.

Well, it seems that these Pure Spring Phoenixes have to be solved first.

The inland river system of Qinghe City is developed, and inland river tributaries less than ten meters wide can often be seen in the city, which is also the origin of the name of Qinghe City.

Unfortunately, with the rapid development of urban construction, these inland rivers have long been the victims of urbanization. The inland river, which is full of all kinds of domestic sewage, not only does not form a beautiful riverbank landscape, but has become a stinky ditch that the public avoids.

The price of houses along the river will be lower than other places, but every summer, the smell of stinky ditches can't be dispersed, and the residents' experience is really poor.

However, for the Pure Spring Hyacinth, this environment is a natural fertile soil!

The water hyacinth that grows in this environment can grow more vigorously than in ordinary clear water.

Lin Zeng had already thought of several places where he could grow water hyacinths.

However, Lin Zeng did not rashly do it himself, but called Professor Feng Xinming of Qinghe University and Liu Yuan, editor-in-chief of Qinghe Daily. (To be continued.) )
