My biological black technology

After walking out of Tang Zhengming's office, Cheng Xiang immediately thought silently to open the system.

A sky-blue light curtain suddenly filled the entire field of vision.

Brand new topics and tasks have been released. Compared with the three thousand experiences of the Hanwang City governance project. The difficulty of this topic is obviously much higher than that of termite control, so the experience is very considerable.

If the previous task was of fragmented knowledge difficulty, then this task is almost close to the level of basic knowledge difficulty.

Therefore, the reward for completing the project is far greater than the gain from termite control in Hanwang City. Thirty thousand experience points are ten times more than three thousand. Cheng Xiang clenched his fist.

You made the right choice, and you can look forward to the future.

A few days later, Cheng Xiang quickly established a research team. The team consisted of nine people, divided into three teams, and each went to collect yeast samples across the country.

Nature is interdependent and life is full of miracles. If there are species harmed by these pollutants, there will naturally be life forms that feed on these pollutants. Just like where a poisonous snake lives, there must be an antidote.

Those that absorb formaldehyde include flocculating yeast, those that absorb aromatic hydrocarbon pollutants, those that absorb candida lipolytica, and those that absorb benzene compounds. They also exist naturally in nature, but they are rarely known.

The first step of Cheng Xiang and his team's project is to collect yeast samples from places where these contaminants naturally exist.

Yeast is a fungus, a single-celled organism. Its function in nature is that of a decomposer and a heterotroph. It absorbs and converts organic matter from the outside into inorganic matter. In this process, it obtains the energy and carbon sources required for life.

In five days, Cheng Xiang and his team drove nearly 2,000 kilometers in southwest China. This was only the distance traveled by car. In addition, there were many places they could not reach by car.

In that kind of place, you can only walk, and a few people ran here and there, leaving their footprints everywhere in the mountains, in the mines, and next to the oil wells. The two master's students who followed Cheng Xiang opened their eyes. Doing scientific research is not like wearing a white coat and standing in a laboratory doing experiments all day long, day after day, year after year.

Their physical strength, mental strength, and energy all experienced a rare test.

At this time, they had just climbed out of a valley in a sub-primitive forest. It was not easy to get in and out of the dense bushes. Cheng Xiang and others looked tired.

Cheng Xiang waved the engineer shovel to push aside the bushes to clear the way. The girl walked in the middle with the sample box in both hands, and the remaining boy walked at the end with the tool box on his back.

Ten minutes later, they finally walked out of the forest. There was an off-road vehicle parked on the side of the dirt road.

"It's out." Cheng Xiang sighed, "Come on, put the samples and tools away and rest."

"Okay, Senior Brother Cheng."

Cheng Xiang pressed the car key to unlock the car, and the trunk opened automatically. The trunk was very large. The space that was originally enough to accommodate six large suitcases was now filled to the brim with a number of numbered sample boxes. Cheng Xiang pushed hard, squeezed out a little space, cleaned the engineer shovel, folded it, stored it, and stuffed it in.

Zhang Xuebin followed closely and put the tool box away, then stretched out his hand towards the girl, "Come on, Ayan. Give me the stuff."

"No, A Bin. I'll do it myself." Chen Yan bit her lips, hugged hard, and lifted the sample box filled with soil to her chest. Then she hummed softly and pushed the sample box to the last available position. .

Returned with a full load.

"Come on, get in the car and take a rest."

Cheng Xiang opened the door and walked into the driver's seat. Zhang Xuebin and Chen Yan got under the back seat. Cheng Xiang took out three cans of soda from the box under the passenger seat.

"Come on, continue."

The three of them lay on the seats and panted heavily. Each of them drank from a can.

"Although soda doesn't quench your thirst, it's quite enjoyable to drink," Zhang Xuebin said.

"That's right, otherwise why would Coke be called Feizhai Happy Water?" Cheng Xiang said with a smile.

"Senior brother, I really can't tell. You also know Feizhai Happy Water." Chen Yan said.

"Of course, we are engaged in research, but doing research does not mean being separated from society." Cheng Xiang said hehe, "On the contrary, those of us who engage in scientific research are the small group of people who are truly at the forefront of mankind. When it comes to fashion, , in terms of trends, who can compare with us."

"We are the ones who really lead and set off the trend!" Cheng Xiang said seriously.

"Senior Brother Cheng is right. I'm convinced. Those who do scientific research are the most fashionable people! It's respectful to do it first." Zhang Xuebin held up the Coke can and poured it cleanly.

"Done." Cheng Xiang raised the Coke can.

"It's done." Chen Yan rolled her eyes at Zhang Xuebin beside her and raised it too.

After drinking Coke, my burps taste like carbon dioxide.

After collecting the final samples planned by their team, the three of them were very relaxed and slumped on the chairs. After blowing on the air conditioner for a while, Cheng Xiang started the car and the three of them were ready to start their return journey.

"Senior brother, you may not know that since you solved the stubborn problems of Hanwang City for more than ten years last year, you have become someone else's child in our generation. From time to time, the instructor will give us lectures and encourage us." Chen Yan smiled. said.

"Haha, is that right?" Cheng Xiang said with a smile, "Then you have to work hard and strive to become someone else's child. This project is also an opportunity for you now, so perform well. Try to achieve good results."

"Yes, senior brother." They both nodded.

One day later, three groups of people who traveled across the country reunited in the laboratory.

There are three sets of samples, the weight of the samples alone is more than 500 kilograms, and hundreds of categories are labeled. Therefore, it is no easy task to extract the target bacterial species from hundreds of categories and more than 500 kilograms of samples.

"Wen Li, next, you come and lead them to process these samples first."

"Okay." Chen Wenli nodded.

After arranging his work, Cheng Xiang immediately drove his eDonkey to the dormitory. The dormitory had prepared a large amount of food last night. In order to save more food, Cheng Xiang bought a large refrigerator.

Take enough food and put it on the table. Except for the stools, everything under the table is covered within reach. Seeing so much food, Cheng Xiang took a deep breath. Eating for others was a kind of enjoyment, but he ate these foods entirely to replenish the energy consumed by his body. He not only had to eat quickly, but also tried his best to resist the indoctrination of knowledge. During the process, there is severe pain caused by the rapid consumption and replenishment of energy.

Moreover, during the resistance process, you must keep your brain awake until the end, because once you pass out midway, the effect of knowledge infusion will stop at the last moment before coma, and a large amount of experience points will be wasted.

But even so, Cheng Xiang will try his best to light up more knowledge, not because he likes to be abused, but because after comparing the lighting process several times, Cheng Xiang found that every time he lights up more knowledge than the previous maximum number of lights up in a single time, , the brain's imagination, thinking speed and acuity will be significantly improved. To put it simply, it can make the brain smarter.

How can Cheng Xiang not know what having a smart brain means to researchers? He even understands the value of it better than others.

The biggest advantage is that you can learn some knowledge by yourself and light it up without spending experience points. Therefore, even though the process of lighting up was a little painful, Cheng Xiang was still happy with it.

The big summoning spell summons collections and tickets, come and hit me.
