Lin Zeng was immersed in making a set of perfect jewelry that he could achieve at the moment, in order to propose to Jiang Hua.

In fact, although these studies are expensive, they are not difficult to complete with enough time.

However, in the work of selecting the main plant material for the jewelry, Lin Zeng changed the plan dozens of times, which is the main reason why the study did not have a slight eyebrow until the summer.

After careful selection and repeated experiments, Lin Zeng finally chose a tall and long-lived woody plant as the main plant material for refining this kind of jewelry.

The trees of this plant are almost invisible in the southern city of Qinghe. However, its core is a snack that is suitable for all ages and loved by everyone.

Walnut, because the inner kernel resembles a miniature brain, has become a good product for strengthening the brain in the Chinese population, which is smart for children to eat, and life extension for the elderly, and to prevent dementia.

The walnut variety that Lin Zeng chose was not a walnut suitable for consumption. Edible walnuts with thick nuts and thin shells are far from the purpose of his refining.

The plant raw material he chose to refine was an iron walnut variety produced in the primeval forests of southwest China. This wild iron walnut has obvious spikes, prominent edges and corners, and a hard shell, and is usually sold as a walnut, which is not a particularly high-end variety in the market for walnuts.

However, after comparing the various varieties, Lin Zeng decided that it was the most suitable plant for refining.

Lin Zeng's refining experiment told him that his judgment was not wrong.

This walnut variety is indeed the most suitable plant.

Once the raw materials have been selected, the subsequent refining process is much simpler.

With a lot of rune learning and a focused refining process, Lin Zeng finally obtained the plant seed in his thoughts.

"Microspace walnut seeds. ”

Of course, this plant made by Lin Zeng is only the first condition for making jewelry.

This walnut seed does not grow necklaces, bracelets, rings and other jewelry directly from the tree, it is only a walnut the size of a soybean.

Because of the addition of pocket runes, microspace walnuts can only grow up to a height of thirty miles, and the size of the fruit varies from mung beans to soybeans. Its growth rate is slow, and if it follows its instinctive growth rate and does not use any fertilizer and micronutrino catalysis, it will take Lin Zeng five years at the earliest to harvest its walnut pits.

Lin Zengke couldn't wait five years to implement his marriage proposal, and by that time, the daylily would be cold.

Therefore, he planted a microspace walnut seed in a flower pot, placed it on his workbench, spared no effort every day, and did not hesitate to water the fertilizer micronuno solution, with a mentality of promoting the growth of seedlings.

Jiang Hua only regarded Lin Zeng's behavior these days as no different from his previous research.

Recently, she has been full of interest in developing the land in the back mountains, and has been busy running around the nearby village committees, renting land, and buying a single-handed cultivator and weeding machine online, preparing for the development in full swing.

After the microspace walnut was planted, Lin Zeng was not idle when he was waiting for it to bear fruit.

He needs to prepare other ingredients to make the final jewelry.

Such days are not easy for anyone to notice, and they pass quickly in the blink of an eye.

It wasn't until Lin Zeng received a call from an old lady that he realized that it had been almost two months since he started researching proposal jewelry.

The lively summer of Qinghe City also shows its power as a furnace city in the country.

Lin Zeng received a call from Mrs. Liu Huameiyin.

This famous designer, who settled on the other side of the ocean, returned to his roots in his later years and returned to Qinghe City to settle down.

Well, although for Liu Huameiyin, whose parents are from the northern capital, Qinghe City is actually not a fallen leaf. However, her preference for this city of plants still made her settle in Qinghe.

Regarding plants, Qinghe City has been widely known throughout the country and even the world in the past two years.

More and more plant spaces, community farmers' markets everywhere, and building facades with colors and leaves all make the city more and more like a sprawling forest city.

I have to say that such a characteristic city has a fascinating charm.

Let's just say that the plant decoration on the different exterior walls of each building has become a very famous scenic spot in Qinghe City.

The Qinghe municipal government made the wise decision to spend the renovation of traditional tiled facades on a new plant decoration. To this day, the Qinghe Municipal Government, which has tasted the sweetness here, is still one of the big customers of Lin Zeng Heterodu Greening Company.

The number of urban buildings covered in greenery is constantly increasing.

In particular, the exterior walls of the building have been greened, and the plants have formed branches and leaves, and the leaves are dense and the flowers are flourishing.

In the tourism forum of Qinghe City, there are also nicknames for different buildings.

For example, the dormitory of a medical company originally located in General Lane is a steel structure house in the 90s, which is sturdy but not very beautiful in appearance.

Originally, for the sake of the city's appearance, the government planned to carry out tile wall decoration, but after investigating the construction of exterior wall plants in some schools in Qinghe City, it immediately changed the plan and changed from tile wall to exterior wall greening.

It is one of the first buildings in Qinghe City to carry out green renovation projects.

At the time of this decision, the residents of the community still had quite a lot of opinions.

They had seen creepers on the flyovers, and they thought that if the leaves were flourishing, they would attract insects to the dwelling, and if the leaves were yellow, the dry vines would be even uglier if they climbed the walls.

However, in the first summer of greenery, this protest completely disappears.

The exterior wall plant selected by Xenodu for the dormitory of the medical company is a pink rose with a large flower shape and a leisurely fragrance. It climbs vines well, and the branches have fine sticky hairs that can be firmly attached to the wall without harming the wall.

When the leaves are lush and the pink flowers are in full bloom, these buildings, which originally looked dilapidated and old, suddenly changed their old appearance into a large garden full of pink roses.

The flowers are hidden in the emerald green leaves, and they bloom all year round, not like ordinary climbing plants, after withering, but the walls appear more hideous, but no matter the summer and winter, they are all verdant and pleasant, and the flowers are lovely.

Especially in the summer, residents living in the dormitories of medical companies noticed that the indoor temperature dropped by several degrees in the sweltering heat of Qinghe City after the exterior walls were covered with greenery.

In the past, when I returned home, it was as hot as indoor and outdoor, so I had to turn on the air conditioner quickly when I got home.

Nowadays, there is a significant temperature difference between indoor and outdoor. The dense flowers and foliage of the exterior walls help the walls block the hot sunlight and provide a cool indoor environment for the occupants.

Because the exterior wall of the medical company's dormitory is planted with pink roses, this place is called the "Pink Rose Garden" at the Qinghe City Tourism Forum.
