Chen Chengcai sat down and ate a few bites of food, and he felt that his brain was buzzing.

This is a bug in the system, and every time a large amount of reputation points comes instantly, there will be a slight 'concussion'.

This time the shaking was much worse than the last time. So he went back to the lab with his meal.

He called up the system while chewing his rice, and then the whole person was confused.

A string of digital realities on a translucent screen, and it's growing.

10,000... 100,000... 200,000... 500,000!

It's not stopped! The numbers are still tumbling.

700,000!

90！

1 million!

Chen Cheng covered his heart with his hand, because he felt that it was beating too hard and might suddenly pop out.

After more than an hour, the reputation value finally stopped at 1,285,000.

This.... Where did it come from?

Is it because the super urease microbes are widely reported, and millions of people revere me all of a sudden, and then contribute prestige points?

Thinking of the "shock series" news just now, Chen Cheng feels that this should be the case.

This number, that is to say close to one in ten people in the province, is appreciative of what he has done.

Excluding the elderly and children, this ratio is not low. You can't expect to be recognized by everyone, that's unrealistic.

Looking at such a long string of numbers, Chen Cheng felt a little upset.

How many experiments must be done!

He felt like he had won the grand prize, and he had endless wealth in his hands.

It is the wealth of realizing an agricultural power.

After counting the reputation points a few more times to confirm that they were not fake and would not disappear suddenly, Chen Cheng quit the system contentedly.

The food on the table was already cold, but he couldn't wait to start the experiment when he was still in the mood to eat.

Wang Kai saw Chen Cheng with a smile on his face coming out of the room, and asked suspiciously: "Old Chen, so happy, what are you doing inside?" ”

Chen Cheng raised his eyebrows and said, "I did something that made me extremely happy." ”

Wang Kai walked over and patted him on the shoulder sympathetically: "Lao Chen, you need to find a girlfriend." ”

"Get out."

"Okay."

The two were chatting, and Ding Tao raised his head from the microscope and looked at Chen Cheng in surprise.

"What's wrong?" Chen Cheng hurriedly asked.

It can't be that there is something abnormal on the rhizome section of the soybean seedlings, right?

"Lao Chen, come and see, this thing is amazing!"

Hearing Ding Tao say so mysteriously, Chen Cheng hurriedly put his head in front of the microscope.

Under the microscope, the rhizome of the soybean seedling is clearly visible, including a scaly-like epidermis and occasionally a round stomat.

Within a minute, Chen Cheng had discovered an "anomaly" that Ding Tao had not spoken—on another slice, he had found some bulging packets on the rhizomes of soybean seedlings.

"What is this?" Chen Cheng frowned.

"I think it's a nodule, but I'm not sure. Because it stands to reason that such a small soybean seedling should not be able to form a symbiosis with rhizobia. Ding Tao said.

Chen Cheng raised his head, thought for a while, and said, "Change the electron microscope and take a look!" ”

Ding Tao immediately moved the slice slide to the electron microscope.

In general, to observe plant tissues, a light microscope is sufficient.

Optical microscopes use visible light as the light source and focusing mirrors use optical lenses, which can be magnified up to 2000x, and are often used to observe the fine structure of the sample surface.

Electron microscopes, on the other hand, use electromagnetic lenses to replace visible light with high-energy, short-wavelength electron beams. The magnification of the electron microscope can be as high as hundreds of thousands of times, and the crystal structure, fine structure, chemical composition, and electron distribution can be observed.

Now he's using an electron microscope to see what the tiny bulge on the rhizome he just saw is.

The electron microscope in their lab is the EVO18 series, which can be regarded as a high-end model.

Although it was a little old, it was also Zhao Feng who gritted his teeth and matched Chen Cheng at that time.

Ding Tao opened the dust cover, turned on the power of the microscope, and turned on the monitor next to him at the same time.

Advanced electron microscopes are equipped with a special display and manipulator that allows the sample to be placed in the chamber and the distance and orientation of the microscope lens can be controlled by the manipulator outside.

It's very convenient.

With Chen Cheng's subtle operation, the image on the monitor gradually became clearer.

Ding Tao and Tang Qiang were attracted by the strange phenomenon on the image and stuck their heads out for a long time. Even the scumbag Wang Kai also surrounded him.

Chen Cheng stopped the operation and let the image stand still in the clearest position.

"Look, it's obviously a bunch of cells coming together, and from the outside, it looks like rhizobia cells." Chen Cheng pointed to the image that was a mass of gray cells, and said to a few humane.

Ding Tao didn't need his instructions, and immediately searched for pictures of rhizobia cells on the computer next to him.

After careful comparison, sure enough, the cell structure is very similar, and Chen Cheng is almost certain that it is rhizobia cells.

Why do you say almost, because in the middle of that mass of cells, there are some other cell structures, but they are obviously not soybean rhizome cells.

He frowned at the cell, and suddenly raised his hand and slapped it on the back of his head.

Wang Kai exclaimed: "Lao Chen, be lighter, don't slap your genius head badly!" ”

Chen Cheng ignored his jokes and said to Ding Tao: "Aren't these cells super urease microorganisms!" ”

"Really?!"

Ding Tao and Tang Qiang squeezed to the monitor and tilted their heads to observe carefully.

They had never seen the cellular structure of a super urease microbe.

Chen Cheng began to think about the reason for this strange phenomenon.

In general, rhizobia invade the host root and stimulate certain cells in the root cortex and middle column sheath, causing strong growth of these cells, causing the local expansion of the root to form a nodule; Rhizobia colonize the roots, and plants supply rhizobia with mineral nutrients and energy.

Rhizobia can fix free nitrogen in the atmosphere, provide nitrogen nutrients for plants, and present a symbiotic phenomenon with soybean seedlings.

And now the super urease microorganism has also appeared in the nodules of the rhizomes of soybean seedlings, and is mixed with rhizobia.

Chen Cheng feels that they have formed another subtle symbiotic relationship, which is why the rhizomes of soybean seedlings develop nodules very early.

There is no doubt that the earlier the nodules develop, the more beneficial it will be for the growth of soybeans.

While he was thinking, a man walked through the laboratory.

"Huh! Aren't you Academician Zhou's full-time driver? Wang Kai recognized him and said in surprise.

"Yes, yes, I'm Academician Zhou's driver, Xiao Li."

The man walked over to Chen Cheng with a smile on his face, and took out an envelope from under his arm and handed it to him.

"Teacher Chen Cheng, this is what Academician Zhou asked me to hand over to you personally."

Chen Cheng hesitantly took the envelope and saw a line in the middle.

"Hanxi Provincial Agricultural University, Agricultural Technology Class Chen Cheng, Received."

The doubts in his heart deepened.

Who still writes letters these days?

When his eyes looked at the bar of the cashier, a layer of goosebumps suddenly appeared all over his body.

"Yuan Nong's own handwriting."
