Uncle Li finally finished spraying and came out of the corn field with a sprinkler on his face.

"Xiao Chen, I'm really lucky to have you!"

Chen Cheng said embarrassedly: "Uncle Li, let me tell you something, your corn yield will increase by 10% this year." ”

"What?!" Uncle Li and his wife grew their mouths in surprise.

"Xiao Chen, if you don't reduce the production by half, I'm thankful, where do you dare to expect to increase the production."

Uncle Li sat on the edge of the field, squinting and gulping down the mash soup.

The peasants watched the sky and ate, and they were obedient, never asking for extravagance or complaining.

Chen Cheng also sat down leisurely.

Now that the reputation value has run out, and there are no experiments, Han Buping can't get the rice pollen he wants.

He felt that lying on the edge of the field was better than going back to see Han Buping's stinky face.

Just as he was about to lie down, the system suddenly spoke.

【Ding! Cultivated successfully! Congratulations on getting your second new variety. 】

"New variety?!"

Chen Cheng hurriedly projected his consciousness into the super laboratory, and saw a 3D projected corn seedling appear in the middle.

[After calculation and analysis, this batch of corn was sprayed with endosperm hormone solution, and some corn genes that had been golden, and new varieties were produced. 】

"It's... What kind of breed is it? ”

Chen Cheng was a little confused.

[This new corn variety will have a larger endosperm structure and at the same time have an embryo structure with genetic characteristics.] 】

"So perverted?!"

Chen Cheng said his perception had once again been challenged.

Originally, he thought that this batch of corn would only have endosperm, no germ, and could not be planted. But I didn't expect that some of the flowering and pollinated corn kernels had been genetically fused with the newly goldened corn kernels.

A new and improved variety was created.

At this time, the system prompt sounds again.

【Ding! The number of new varieties has reached 2, and you can get a prize. 】

"Prizes?!"

Chen Cheng remembered that the system had prompted before that whenever the number of new varieties reaches 2, there can be a chance to get a reward.

He hurriedly clicked on the system panel to see what prizes were available.

A list of pictures of prizes were projected on the panel, all of which were instruments and equipment that Chen Cheng had never seen. The introduction says that these devices can be extracted into the real world.

Chen Cheng was overjoyed.

His lab was running out of equipment.

However, it is a little regrettable that only the first [Bio Replica Machine] is lit up in the current column of equipment pictures.

That is, there is only one prize to choose from.

He clicked on the introduction of the plant reproduction machine.

[Name:Bio Replica Machine]

[Grade: Grade 1 (Plant Spore Grade)]

[Rate: 1W/h]

【Remaining uses: 10】

[Function: Put in the biological sample that needs to be reproduced, fill the required raw materials, and the creature can be reproduced.] 】

After reading the introduction, Chen Cheng roughly understood the use of this prize.

That is, this creature replicator is currently capable of replicating spore-level creatures at a rate of 10,000 per hour.

Replicating requires an original sample, as well as the raw materials needed to reproduce it.

To put it simply, it is a miniature spore production line.

"This stuff is very good!"

Chen Cheng felt that he had found a solution to Han Buping's dilemma.

With this biological replica machine, he can create the rice male pollen that Han Buping wants!

Chen Cheng looked at the flashing [Extract Now] button and quickly stood up.

"Uncle Li, you remember to fertilize and spray antidote today."

With that, he got up and ran to school.

Uncle Li shouted behind him: "Xiao Chen, ride my tricycle!" Silly boy, the legs are fast with wheels! ”

Chen Cheng rode the electric tricycle back to the laboratory building and walked into the laboratory.

Before he could sit down, he couldn't wait to get a little more on [Extract Now], and immediately, a brand-new bio-replica machine appeared on the workbench in front of him.

The replica is about the size of a scanner, pure white, and looks like a scanner.

He plugged it in, and the bioreplica machine emitted a "Didi" start-up self-test sound.

Chen Cheng studied the operation panel of the replica machine and basically understood how to operate it.

The equipment is available now, but where can I find the samples?

The last time they pollinated, they ran out of male pollen.

Otherwise, when Han Buping asked questions in the morning, he would have taken out the remaining pollen directly.

"Hey, will there be some residue in the sample bag that contained male pollen last time?"

For bio-replicators, only one sample is needed to reproduce.

Chen Cheng hurriedly called Wang Kai, and he handled the sample bag last time.

Sure enough, Wang Kai said that he threw the sample bag in the closet and could still find it.

Chen Cheng asked Wang Kai to immediately send the sample bag to the laboratory and set out to find the raw materials for reproducing the pollen of the male flower of rice.

Rice male pollen with fertilization ability is essentially a microspore formed by meiosis of pollen mother cells.

These mononuclear microspores undergo mitosis to form a mature pollen containing 2 gold and 1 vegetative cell.

Therefore, the raw materials needed to reproduce pollen are the basic substances that make up the spores: proteins, nucleic acids, phospholipids, and so on.

These basic materials are stocked in most laboratories.

When he found all these raw materials, Wang Kai also arrived with a sample bag.

Chen Cheng picked out a few intact ones from the residual pollen in the sample bag under the microscope and placed them in the sample chamber of the bioreplicator.

Load the raw materials, set the number of replicas to 1W, click [Start Replica], and the rest of the replica machine will be done automatically.

Wang Kai stared at the novel equipment in front of him, he couldn't understand what Chen Cheng was doing, and his face was full of questions.

"Lao Chen, what kind of machine is this?"

Chen Cheng said: "Biological replica machine. ”

"Can it reproduce pollen?" Wang Kai was surprised and lost his voice.

Chen Cheng nodded.

Wang Kai: "No! ×3”

He tilted his head and looked at it for a long time, and suddenly said, "Can this thing copy human pollen?" ”

Chen Cheng ignored him.

Wang Kai continued to use his imagination: "Really, Lao Chen, if you can reproduce human pollen and use it to treat infertility or something, we will make a fortune!" ”

Chen Cheng said: "When you need it in the future, I will do it for you for free." ”

Wang Kai waved his hand again and again: "That's not necessary, I'm very healthy." ”

The two were talking energetically, and Zhang Zhimin took Han Buping into the laboratory.

Chen Cheng hurriedly picked up Wang Kai, walked out of the inner laboratory, and closed the door smoothly.

"Teacher Zhang, why are you here?" Chen Cheng asked.

Zhang Zhimin glanced at Han Buping, meaning that he had to come.

Han Buping said expressionlessly: "Xiao Chen, you said that you showed me rice pollen in the afternoon." ”

Chen Cheng said: "It's not yet one o'clock, and I haven't had lunch yet." ”

Han Buping said with a smile: "After twelve o'clock, it will be afternoon." What's the matter, you can't get the pollen out? ”
