Chapter 69 (1/2)

Of course, can this purification tree change the air within its range into higher quality air?

The answer is, of course! But if the air on the street has become the level of purification tree 1.0, who will sell his purification tree 1.0 and his purification tree 1.0mini to?

So for the sake of sales of other products, the performance of purification tree 1.0 plus is artificially limited.

Not only that, the life span of this kind of purification tree is less than three years. After three years, it will decompose into the soil and become ”fertilizer”, which is also restricted by Tang Shizhe. The external reason is that the life span of these trees is extremely limited because of high-intensity work!

In any case, it is Tang Shizhe's schist who is responsible for the production of purification tree. As long as he doesn't say it himself, no one will know these doctrines.

”Then the price is next!” After a pause, he continued.

”It costs only 100000 soft dollars! you 're right! Only 100000 soft coins are needed! ” Tang made a gesture of ten with his hand.

After all, they can purify the air of the city and improve the happiness index and health level of residents.

Take a city with a diameter of 10 kilometers as an example. If you want to improve the air quality in the city, you need at least 3000 purification trees plus, which is a sufficient fund of 300 million!

And this price does not include installation! The city hall is responsible for the installation cost.

”Mr. Tang, this price is a little expensive! A small city needs hundreds of millions of dollars... ”One reporter raised his hand and asked.

”I haven't finished yet. Please listen to me.” Tang Shizhe pressed his hand.

”We decided to donate half of the proceeds from the sale of the tree of purification plus to Titan Education under Titan group!”

”Titan education will use this fund to build hope schools all over the country, and all expenses of children in school will be borne by Titan education!”

”What's more, we can make sure that these children have enough and good meals, and that they can eat meat at all meals.” Tang's words caused cheers from the audience.
