On this day, Yan Ruihan took the Pu Demon out of the city and went to Mohe.

The location of the mounds is unique, at the intersection of shrubs, grasslands and forests. The wide Mo River cuts through the bushes and grasslands from north to south, and enters the forest and heads into the distance. The wide highway and several railroad tracks extend to the northern base and the dark blue base, respectively, forming the transportation hub of the mounds base.

The base's large and only airfield is built in the northernmost part of the base, next to the second army of the base, and the other three regiments are firmly guarding the base to the west, south and east. The planes at the airport are almost all military, not that civil aviation is not allowed to take off, but there are also civil aviation colleagues who go to the northern base and the deep blue base. It's just that α virus is raging all over the world, the situation is the same everywhere. At first, people were running around in panic to find their loved ones. However, after a long time, I saw the colleagues around me, relatives and friends fall to the ground by this irreversible global crisis, and round after round of evolutionary viruses made them unable to regenerate many futile thoughts.

Humans are very adaptable species, and once they realize that they can't get through this crisis, they will fall silent and silently accumulate strength.

The Mounds Base is more of a gigantic city than a base. Tens of millions of people live in the base, and there are equally large numbers of people outside the surrounding base. They keep the base running like blood, and the base provides them with force protection, supplies, medical care, and most importantly, antibodies to α virus.

The people living inside the base produce all kinds of necessary daily necessities and equipment, while the people outside the base are more free and messy. Many people are appointed by the base or directly sent by the base to plant crops and breed, and the base provides fields, grain seeds and new agricultural tools developed by the base, and the income is used to supply the people of the base.

At the beginning, it was not that no one planted it privately for their own use, but later Yan Ruihan directly ordered that 10,000 square kilometers outside the base belonged to the base territory and was protected by the base. Now the people who live outside the base are not as governed by as the people inside, but they can also enjoy the same preferential price as the people inside to buy the food produced on the ground, and everyone has nothing to object to.

In the rice fields above the riverbank, Yan Ruihan carefully observed the rice ears in several experimental fields, and went ashore without saying a word. When Yan Ruihan walked out of the experimental field, the relevant personnel hurriedly closed the experimental field.

"Gu Lin, section chief of the research report, under natural conditions, the same type of rice seeds, this year's yield per mu is expected to be reduced by 10% compared with last year. At the same time, he also compared other crops, and the results showed that the yield was reduced to varying degrees compared to last year. Zhongli followed by his side and reported to Yan Ruihan, who was washing the mud from his legs and feet.

"Have you found out what the reason is?" Yan Ruihan asked.

"I checked," Zhongli replied, "It is caused by the decrease in the number of bacteria in the soil, and there is no definite answer as to what caused the decrease in soil bacteria." Section Chief Lin boldly speculated that it might be related to the α virus, but because the virus is too infectious and the risk of extracting samples is too great, there is no way to do experiments to confirm it. We've told the Northern Base and Deep Blue Base about this discovery, and they're taking it very seriously, saying they'll get back to us as soon as they become informed. ”

"Okay. ”

After reporting his work, Zhongli went to get busy. The Pu Demon followed Yan Ruihan all the way, sitting on the grass, looking at a few experimental fields and not knowing what he was thinking.

"Demon, what are you doing? After putting on his shoes and socks, Yan Ruihan turned around and saw the Pu Demon looking at the rice field, so he walked over and squatted with him to look at it.

"Well, Yan Yan, are you done?" Now that Zhongli can solve many things in the base, Yan Ruihan doesn't have to go to the office building every day, only some urgent and uncertain needs to find him. Other times, Yan Ruihan was training physical fitness, and the other was watching and teaching the Pu Demon Demon's homework. There is also more time to take him out to play.

In the past few days, the Pu Demon Demon saw that Yan Ruihan was busy with this soil and grain matter, and he also listened to it. He asked with some concern, "Yan Yan, if the rice fields keep decreasing yields, will we have no food?"

"Yes," Yan Rui'an sighed, touched his head and continued, "Because of the α virus, half of the people in the world have died, and Dongzhou's side is much better than other places because of the earliest antibodies researched. But α virus evolves itself fast, and people are still following α virus. If the production of agricultural products is reduced, it will be even more difficult. Although our base can now supply some food for indoor soilless cultivation, the output is far from being able to supply all people. Besides, the root cause has not been found, and no one dares to guarantee that soilless cultivation will not face the problem of reduced yield. ”

"The vitality of the soil is weakening," the Pu Demon said, seeing that Yan Ruihan was so distressed, the Pu Demon also wanted to help. He gestured, "These rice fields, from right to left, the vitality in the soil is weakening. ”

From right to left, the experimental fields are selected by year, and the leftmost is this year. Originally, it was selected to work on other topics, but due to the reduction of crop yields, it was specifically used to study this problem. Considering that the soil contains bacteria as the vitality of the soil, the observation of the Pu Demon is not bad. But it still does not solve the reason why the vitality, that is, the microflora is weakening year by year.

This Pu demon really didn't know, he only keenly felt that there was something that affected the survival of the life force in the soil, but the life form in the soil was too small, and the reaction was very weak, and he couldn't use his spiritual power now, so he couldn't feel such a subtle feedback.

didn't help, and the Pu Demon followed behind Yan Ruihan a little sullenly. Yan Ruihan felt that it was nothing, and patted his lowered head comfortingly. So many experts in various industries have been studying for several years before making a little progress, and it is not bad at this time. If the Pu Demon found the key at once, he would be surprised.

"General, the First Legion reports that there is a group of people in the east who are close to the base, they are free mercenaries, and the leader is Fancheng. At this time, Yan Ruihan's personal guards came over to report.

"Let Li Jun let people in," Yan Ruihan was happy, "Let's go, demon, brother will take you to see your old friend." ”

The two quickly returned to the city, and as soon as they arrived at the door of the reception hall, a black shadow rushed to them, and a fist with the wind and momentum attacked Yan Ruihan's façade. Yan Ruihan was followed by the Pu Demon Demon, and he couldn't hide. I saw that he was short on his side legs, staggered the oncoming fists, and at the same time struck with a heavy fist with his right hand to meet a circle of black shadows that fell into the air.

The black shadow immediately blocked with the other one, kicked his hind leg at the same time, and then quickly raised his foot to give Yan Ruihan, who was chasing over, a leg whip. Yan Ruihan did not retreat but advanced, and also kicked his right leg horizontally, kicking Fan Cheng in the air.

"Good brother, you don't retreat but advance in this kung fu, you don't look like you're injured at all!" After closing the momentum, Fan Cheng looked at Yan Ruihan and patted him on the shoulder with joy. Fan Cheng and Yan Ruihan used to be comrades-in-arms of the special forces, but later retired due to some things. After the global virus, major political systems have collapsed, and the economy has also regressed rapidly. Fan Cheng simply pulled some veterans and skilled people to form a wolf blood mercenary group, which is not under the jurisdiction of any party, but often cooperates.

Before, he received the news that Yan Ruihan was attacked by KT mercenaries and immediately rushed to help, but unfortunately when he went, the KT mercenaries had already fled, and Han Xiong and they also arrived immediately, so it was not easy for Fan Cheng to participate again.

Two days ago, he received the news of Yan Ruihan's return, so he came over non-stop.

"Thank you, borrow your good words. Yan Ruihan raised his eyebrows and said. Yan Ruihan was also very happy to see his old friends coming, Fancheng was one of the few friends he could rarely talk to.

"You guy. Fan Cheng scolded Yan Ruihan with a smile, sat down and drank a sip of tea to moisten his throat, he looked at the Pu Demon Demon who had been looking at him curiously for a long time and asked, "This is your newly recognized brother?"

As soon as Yan Ruihan entered the door, Fan Cheng saw the boy walking beside him. Fan Cheng had known Yan Ruihan for many years, and had never seen Han Xiong, Zhong Li, and anyone other than Bai Bing by his side. But even they were only following behind Yan Ruihan, and this person not only went in and out with Yan Ruihan, but also walked in the front position beside him, carefully protected by his old friend. Tsk, that's a treasure.

"Well, this is my younger brother, the Demon Pu. Yan Ruihan said to Fan Cheng, and then to the curious Pu Demon Demon, "Demon Demon, this is Fan Cheng, if you fight in the future, my brother will look for him." ”

After waiting for a long time, he didn't hear the afterwords, Fan Cheng Taotao looked at Yan Ruihan with a surprised expression, "This is the end?"

"Well, it's over, what else?" Yan Ruihan looked even more inexplicable than him, and added, "Don't forget the meeting gift." ”

"Tell me about my heroic deeds, I feel like a thug when you say that. Fan Cheng said speechlessly. He was born handsome and straight, and making this look makes people look inexplicably funny.

The Pu Demon Demon was amused by his changing appearance, this person is too funny. As soon as he entered the door, he noticed Fan Cheng, his move was crisp and neat, and his moves were swift and sharp, and Yan Yan should be between him and Yan Yan before he was injured. is tall and handsome, but his eyebrows are raised, adding a touch of grace to his bold and flamboyant aura.

"Hey, demon demon, what kind of greeting gift do you want?" Yan Rui, who was like an ice cube, had never won a fight, and seeing the Pu Demon snickering on the side, he quickly shifted his target.

"Hello Fancheng," Pu Demon was still very polite, and returned to Fancheng, "No need, I have given me all the Yan Yan I like." ”

"Poof, Yan Yan?!Hahaha......" This "Yan Yan" made Fan Cheng laugh and slapped the table, his old friend was silent on weekdays, as cold as a piece of ice, with these two words, it inexplicably made people feel that the ice was hot an octave, and they couldn't get cold if they wanted to.

"Yan Ruihan, where did you find such a precious brother? "The Pu Demon is clever and cute, he thought it was interesting when he stared at Fan Cheng just now, he didn't expect to be so bold and so fun.

Yan Ruihan's eyes suddenly turned cold, and he felt that the temperature around Fan Cheng had changed. That's just a few words, no way, no need to make excuses for the beating.

The Pu Demon Demon was also taken aback when he heard this, this person wanted to take him away from Yan Yan? The Pu Demon Demon stopped doing it, "Yan Yan, let's beat him out!" When he came back, he heard Yan Yan say that it was his friend who was polite to him, but he didn't expect this person to be so bad, he actually wanted to separate him from Yan Yan!

"Don't, don't, I'm kidding," feeling that he was about to face a fist and kick that would split his head and cover his face, Fan Cheng wisely reined in. He had never seen Yan Ruihan protect people so much, he was very curious, but he didn't expect to hit it as soon as he tried it. Although he also thinks the Pu Demon is quite interesting, but life matters.

After thinking about it, Fan Cheng took off the watch in his right hand and handed it to the Pu Demon Demon, "To the Demon Demon, Brother Cheng apologizes, you will be my brother in the future." ”

Yan Ruihan could see at a glance that this was not an ordinary product, Xizhou's newly developed wrist-type protective shield, which can generate a protective shield when a person is attacked, and it takes a few minutes and a second to start, and it is passively triggered. Although it is a disposable product, it has just been developed and sought after, and it has to be said that although M continent is medically backward, it is still much ahead of other continents in terms of weapons and ordnance.

This thing was not sold to the outside world at all, and neither did Yan Ruihan. The mercenaries in Fancheng have a larger contact with the outside world, but it probably took a lot of effort to get this thing.

Pu Demon didn't know this, looking at Fan Cheng and handing it to him, Pu Demon Demon asked first, "Then do you still want to take me with you?" He Pu Demon is not easy to coax, although this person apologized, but he still had to ask clearly!

"No," Fan Cheng said with a smile, "I like you very much, but Brother Cheng wants to take you away, and your Yan Yan is probably going to blow up my corps." ”

After speaking, he added with a half-smile, "Of course, Brother Cheng always welcomes demons to play with me." When do you want to go, tell my brother, and my brother will let someone pick you up. ”

The uncertain Pu Demon turned his head to look at his family Yan Yan, Yan Ruihan nodded to him, "Call Brother in the future." ”

After getting Yan Ruihan's affirmation, the Pu Demon took Fancheng's things with both hands, and replied politely and seriously, "Thank you, Brother Fancheng, the demon will not go with you." ”

"But I can play with you. After thinking about it, Pu Demon added. He thought that Yan Yan nodded, and called his brother again, he was his own person, and he thought that Fan Cheng was also quite interesting.

"Then brother, thank you for being so appreciative. Seeing that the Pu Demon finally accepted the things, Fan Cheng made fun of him. I didn't expect this little guy to be big, but he was quite organized, and Fan Cheng's love for the Pu Demon increased a few points.
