After all, Cui's Alan is there at an age, although he hasn't slept all night, his eyes are a little bloodshot, but he is still in good spirits, seeing that the sky is already bright, Lin Bei is taking a routine bath, Cui's Alan circled around the waterhole, and asked very strangely: "My lord, why do you want to stop here?" Cui Lan didn't see anything? ”

Lin Beixin said that it is strange that you see it now, those little turtles have already found a cave and settled down, because they are very small, they are afraid of being killed by other fish, so they will not come out, but when they are older, after they have the power of self-protection, the small turtles will come out to fight for food.

Bian Ji came out of the house, stretched, and said suspiciously, "Cui Lan, what were you doing last night?" It made me not sleep well all night. ”

Cui Lan pointed at Lin Bei: "Master, you have to ask your lord, Cui Lan hasn't slept all night." ”

"Oh?" Bian Ji didn't ask any more.

Seeing that they were all washed, Lin Bei got up from the pool, his snake scales were extremely smooth, and when he shook it slightly, the water droplets were shaken off, and he didn't even need to wipe it.

"Your Excellency is going to catch that proboscis today?"

Lin Bei nodded and swam to the edge of the rock: "Exactly, there are more than a dozen proboscis beasts over there, and they can be finished after they are caught, but the proboscis beasts are actually not important, and the biogas digester is the most important." ”

"Adults attach so much importance to this called biogas digester, can you tell us what is the use of the biogas digester at the end?"

Lin Bei only said that turning waste into treasure, but he didn't elaborate on anything else, even if Bian Ji and the others wanted to break their heads, they couldn't think of what kind of treasure the filth of the proboscis beast could become? Isn't it the immortal family's little stone into gold? But that's not a stone, Bian Ji has been stuffy in his heart for a day, and he has been wanting to ask.

Lin Bei asked, "What do you use to make fire?" ”

"Naturally, it's the tunnel and the fire sickle." Cui Lan said as a matter of course.

"Is this kind of fire-taking method inconvenient?" Lin Bei asked again.

Cui Lan hesitated this time: "I don't feel inconvenient. ”

"That's because you're used to it, and there's no better way to make a fire, and I find it extremely inconvenient anyway, and every time you make a fire, you have to take some fluffy grass, and at the same time you have to prepare a lot of firewood, and if the firewood is finished, you have to start again."

"Isn't it all like that?" Zhen Ding on the side of the road.

Bian Ji was thoughtful: "Could it be that the 'biogas digester' that the man said doesn't need a tunnel, a fire sickle and velvet grass?" ”

"You don't even need firewood." Lin Beidao: "Once the biogas is generated, it can be endless, a pond of biogas is enough to use for several months, in addition, the biogas can also be extracted, put into a tank, carry around, take and use, very convenient." ”

Bian Ji and the others were suddenly surprised, a pool of biogas can be used for months? Think about the methane digester that is not very big, but it is so capable?

"Can you cook with that biogas?"

"This must be fine, otherwise what are you doing with it? In addition, the fire is concentrated, so the meal cooks very quickly, saving about two-thirds of the time. ”

The initial role of biogas must be used to cook and boil water, but the more later, the greater the role of biogas, such as heating, such as iron and steelmaking, these can be used to replace charcoal and coal, if the technology is a little more advanced, the steam engine can also be developed, but the raw material is just a small filth, compared to coal, a non-renewable resource, and wood, a slow-growing resource, biogas is really cheap.

Bian Ji and the three of them were moved, they naturally didn't think of so much, but the filth can be turned into fire, and finally it can be used for cooking, which is already beyond their imagination, maybe this is really a 'demon law'.

Lin Bei said: "This biogas digester is related to my next series of plans, so I hope you must pay attention to it and get the biogas digester out as soon as possible." ”

"Don't worry, my lord, I will inform Zhongzhi today." Bian Ji nodded in a condensed voice.

Seeing that the time was almost up, everyone headed towards the academy to meet the hunters.

Just arrived at the place where the school was located, the people didn't arrive, but An Zhongzhi arrived, Lin Bei also saw that Zhen Ding's two guards also came back, and there were two people standing on the side, thinking that one of them was Zhen Ping.

Sure enough, as soon as this person saw Zhen Ding, he came up to salute, calling him a brother, Zhen Ding smiled and helped him up, and said to Lin Bei: "My lord, this is Zhen Ping, Zhen Ping, I have come to see my lord." ”

Zhen Ping's surprise flashed, he must have known Lin Bei's existence for a long time, so he was not afraid, and saluted Lin Bei, "Zhen Ping has seen adults." ”

Lin Bei looked at this Zhen Ping, this person has a white face and beard, and the clothes on his body are quite neat, giving people an extremely clean feeling, his eyes are flexible, and he knows that he is a very shrewd character, Lin Beixin said that Zhen does have a set, just by looking at a shopkeeper in Nanyue, you can see Zhen's vision in terms of candidates, Zhen Ding is like Maitreya Buddha, Zhen Ping is shrewd, and doing business These two impressions are very important, if others look at the shopkeeper's face and black heart, I am afraid that they will be a little more afraid in their hearts, and where will they dare to come to the door again after a time.

Ignoring the greetings, Lin Bei wrote: "You tell me again about the situation of the merchant surnamed Guan." ”

Zhen Ding had already learned about the situation with the guards on the road, and he had already learned that the monster in front of him had great powers and knew people and people, but seeing a big snake in front of him writing on the ground one by one, his face couldn't help twitching, this kind of miracle made Zhen Ping a little frightened in his heart, and said respectfully: "My lord, that person came two years ago, and there are still three days before the Double Ninth Festival of that year"

Bian Ji glanced at him and asked, "How do you remember it so clearly?" ”

Zhen Ding explained with a smile: "My lord, Master, my brother has been smart since he was a child, although he doesn't dare to say that he will never forget, but the merchants he has seen over the years can say eight or nine times out of ten, even if it is several years apart. ”

Bian Ji was a little surprised, Lin Beixin said that he was a strange person, this is the same as the manager of a modern hotel, the basic skill is to remember some big customers, it is said that some time-honored hotel guys are even more powerful, as long as the guest comes once, no matter how many years later, as long as he goes again, the guy can remember what the guest ordered a few years ago, this kind of shop guy is even more popular with customers than the boss.

"You go on."

"Yes, my lord, the merchant surnamed Guan, brought a large box, and was received by the guy at first, but the merchant insisted on looking for me, so I personally received it, and he brought all the specialties of the coastal area, one of which is that pigs do not eat."

"This businessman surnamed Guan once said, pigs do not eat in the deep mountains, a kind of thing dug out for wild boars, the number is very small, the size of a general fist, the skin is red, the food is sweet and delicious, a piece is enough for an adult man to eat, there are slang people who get it by chance, it is regarded as a treasure, usually do not eat, when there are honored guests, it is used to entertain guests, but unfortunately when this businessman surnamed Guan brought it, it may be due to improper preservation methods, it has been rotten, so I refuse, my lord, this is the process."

Lin Bei turned a few times in his heart, it did sound very similar to sweet potatoes, the skin was red, it tasted sweet and delicious, all of which were similar to the characteristics of sweet potatoes, the reason why the merchant surnamed Guan would bring this was probably because slang people regarded it as a treasure, and secondly, it was sweet and delicious, sugar was still a very precious thing in this era, and sweets were considered aristocratic food.

After confirming it, Lin Bei felt that no matter what, he had to go to Zhulu once to find the real thing that pigs don't eat and verify it with his own eyes.
