Zhang didn't understand what the so-called "more than 100 dollars a liter of air" meant, but now he found that the air in the store was really not ordinarily fresh.

It's very comfortable to breathe.

"This ...... Is it the work of these green plants? ”

Zhang opened his mouth wide in disbelief:

"Green plants do have the effect of improving air quality, but this efficiency is too exaggerated!"

The windows of the shop are open, which means that in a non-enclosed environment, the air purification effect of these plants is comparable to that of an air purifier!

The most important thing is that he didn't feel the wind at all!

If all green plants have this kind of efficiency, the air purifier manufacturers that have recently started to speculate will not directly declare bankruptcy?

"This is a special variety that I developed, and it is still in the experimental stage, and the production is limited, so it is just put in the store and sold as a potted plant."

Oakes pointed to the rows of plant species on the shelves that didn't seem to be anything special:

"Although they look no different from common indoor greenery, they are dozens of times more efficient at purifying air.

Not only the adsorption of particulate pollutants such as PM2.5, but also the efficiency of formaldehyde purification and oxygen regeneration. ”

"So, although I'm just a small plant shop, I've been well-known in some small circles for more than a year."

Zhang was already trembling - the guests who came to buy the bonsai did not understand what kind of great scientific research results they were buying!

"Ah, it's not too early......"

Touching his stomach, Oakes reacted, it was already five o'clock, and he hadn't eaten lunch yet.

Moreover, today Goo Gu moved in, and he had to buy canned food and freeze-dried.

As for cat litter......

Are you insulting the IQ of the Elemental Devourer?

"Let's go, go to Eighth Avenue, that's the nearest Chinatown, it's my birthday today, I'm in for a treat, I'm going to have lunch."

"Your birthday...... Today? ”

"How?"

“…… It's nothing. ”

Zhang swallowed.

September 22, the last day of Virgo.

It is said that the obsessive-compulsive disorder will be especially severe in children born on this day.

……

A week has passed, and Zhang's study abroad life has opened a new chapter.

"Meeting Dr. Lin is my greatest luck in my study abroad life!

Dr. Lin is a true genius, not only strong in scientific research, but also humorous and approachable, well, much more handsome than me! ”

Leaving a photo with Oakes in the space, Zhang unexpectedly received crazy likes and messages from his parents, relatives, seniors, younger sisters, and even professors.

This day, Hu started, envy, jealousy and hatred!

"Zhang, then I'm going out, and I'll ask you in the store."

Oakes' voice came from downstairs, and Zhang hurriedly closed the laptop - this was purchased at a discount through the education channel, as a scientist, Oakes's personal computer was obviously not something that Zhang could use casually.

The notebook can be used both in the store and in school, and the configuration and price of this one are very suitable.

A new laptop and mobile phone advanced Zhang's salary for two months.

Zhang smiled like a fool when he learned that he could also advance his salary, and he was so beautiful that he was bubbling.

"Don't worry, Mr. Oakes!"

Zhang went downstairs with his notebook, and Oakes was dressed in a sweatshirt and casual clothes, saying goodbye to Gugu.

"Mr. Oakes, don't you bring a salute?"

"It's just a preliminary preparation, and I have already couriered the instruments, tools and supplies I need in advance."

Oakes lifted his sunglasses, whispered to Coo, straightened up and nodded:

"See you in a week, then."

"Yes, Mr. Oakes, I wish you a safe journey."

Zhang hugged Goo - now he is not afraid of Goo at all, and has advanced to become an exclusive shovel officer -

It's just that Gugu's high IQ makes it more proficient in using the toilet here than Zhang, making Zhang, a shovel official, a little unworthy of his name.

Oakes waved his hand, opened the door and walked out, glanced left and right, and walked to a small alley where there were no people.

A moment later, a small bird soared into the sky.

The sharp-tailed swift, the fastest bird on Earth at the moment, is the form chosen by Oaks to fly in the air.

The average flight speed is 170 kilometers per hour, and the fastest speed can reach 352 kilometers, which is simply the speed of archery.

And with such a small size, even the most sophisticated military radars cannot detect it.

If you just transform into a sharp-tailed swift, your natural speed is limited to the upper limit of what the animal can reach.

But Oaks' changing shape of the sharp-tailed swift is obviously not so simple.

A misty emerald glow enveloped the tiny bird, and Oaks' wings flapped in a sudden increase in speed.

A small sonic boom sounded, and in the next moment, Oaks's flight speed had surpassed the speed of sound!

However, in this state, his defense is very weak, and if he hits something, he will be hehe.

"That's the unscientific side of magic......"

Oakes was already on the sea in an instant:

"Target, Amazon rainforest!"

As a druid, it's safe to say that there's no place on earth that makes Oakes yearn for more than the Amazon rainforest.

Although the depths of the Amazon rainforest are extremely dangerous forbidden areas for humans, for Oakes, who has a wild heart and a natural affinity, it can be counted as his home turf.

In the past few years, when the flight speed could not reach supersonic speed, Oaks had already been here a few times, and some special tropical plants in the store were also brought back from here.

As the world's largest tropical rainforest, known as the "lungs of the earth", the Amazon rainforest plays an important role in the earth's ecosystem.

And if it is used as a place for druids to practice......

Undoubtedly the most suitable place on earth.

The rainforest is full of dangers, with strange plants, ferocious beasts, strange insects, and countless threats, making it impossible for even the most elite modern expeditions to safely explore.

So, if you do some big magic experiments here, you don't have to worry about being discovered at all.

Landing at a high altitude and landing into a box...... No, the cheetah form, although not as suitable for the rainforest environment as the jaguar, is not a big deal.

He cruised the vast rainforest along the Amazon River, perceiving the endless scent of nature with natural magic.

Over the course of a few days, Oakes will continue to deepen his connection with this vast rainforest and further enhance his natural magic cultivation.

In this rainforest, Oakes will receive powerful nature bonuses, which is an extremely important factor in Oakes' intention to pursue a career in environmental protection.

The richer and more complete the ecosystem, the stronger Oaks will be.

Taking advantage of the world's willingness to protect the environment, when Oakes' natural magic attainments can invoke the power of the earth's ecosystem, he will also have the capital to leap forward to the cosmic powerhouse......

"Huh?"

His thoughts snapped abruptly, and Oakes was stunned and stopped.

The cheetah form has a special ability to detect humanoids.

And the phrase "the forest is my domain" is not an exaggeration for the druids.

Now in Oaks's perception that has been enhanced hundreds of times, there is a human in the distance!

"So deep, how can it be?"

It's already deep into the rainforest, who is so daring, or is it alone?

"Whoa—"

The figure vanished, and Oakes began to stealth, slowly approaching his target.
