Xiao County, Hongpo Township, the night is sultry.

In the dark night, there was the sound of horses' hooves, and groups of soldiers and horses hurried away with torches.

The Tang character banner was erected high, bringing a solemn atmosphere to the dull night.

The march was relatively dull, and many of the generals had serious expressions on their faces, occasionally revealing panic.

Located in the center of the march, Li Dao, who was carefully held by a sturdy woman, was drowsy, his body was too small to hold on to the rapid march for several days.

Because it was a retreat, the grain, grass and money had already been transported away by the vanguard, and the soldiers and generals could only eat dry food and hurry, compared to them, Li Dao was much happier.

Because he is traveling with a wet nurse, he doesn't have to worry about being hungry.

Li Dao suddenly noticed that a demon appeared in front of him, holding a huge ghost slashing knife and slashing at him.

What was even more frightening was that he found that he couldn't move, so he could only watch as the ghost slasher slashed at him.

"Ah......h

Stimulated, Li Dao suddenly woke up from his sleep, cheering around, the moonlight was dim, and the night was like water.

"Your Majesty, what's wrong with you?", the nurse asked anxiously.

"Ah, it's okay, just had a nightmare. ”

Li Dao pursed his lips and comforted the nurse with a smile, but his heart was still immersed in the dream just now.

The demon that had attacked him seemed familiar, but he couldn't remember where he had seen it.

After thinking for a long time and no result, it was pitch black ahead, and I couldn't tell where I was at this time, so I asked casually, "Where are you now?"

"I have arrived at Hongpo Township, Xiao County, and I will enter the Taoshan area fifty miles further along Hongpo Township, and it is estimated that I will be out of danger tomorrow. ”

The nurse's face was full of expectant smiles, because she was the emperor's nurse, she knew a lot of secrets, and the mountain god of Momoyama supported them in the Tang Dynasty.

didn't notice that Li Dao was suddenly stunned when he heard this name, and his little eyes were scary.

Xiaozui muttered, "Hongpo Township...... Hongpo Township has both land and ghost group training envoy Dou Jianye, what I dreamed of just now was Dou Jianye, which is not good. ”

Li Dao was shocked into a cold sweat, what was the nightmare just now, it was clearly Dou Jianye who was reminding him of his dream.

Forcibly stabilized his mind, summoned the imperial guards, and ordered: "The night road is dangerous, let the front and rear armies strengthen their vigilance, and increase scout patrols." After speaking, he added slowly: "Let the two generals of the auxiliary country and the town army come to me." ”

The imperial guard was ordered to leave, and Li Dao's face was gloomy, looking around vigilantly.

The more anxious he was, the more he could not show it, and rashly reminded the enemy that it was easy to cause a mutiny at night, and even if he did not mutiny, he would probably panic and give the enemy an opportunity.

Not long after, the two generals arrived on horseback, and Li Dao hurriedly summoned the two to his side and informed them of the enemy attack.

After the three of them discussed for a while, the two generals quickly left, and it didn't take long for the news of the enemy attack to be conveyed one by one, and the originally sleepy soldiers suddenly became energetic.

Although he still maintains a casual and true line, he is actually loose on the outside and tight on the inside, always ready to fight.

Seeing that the battle order was announced, Li Dao took a deep breath, his eyes a little crazy.

"Li Muzhi, since you want my life, then come and take it. ”

is ruthless in his heart, it seems that he is more than lucky tonight, since this is the case, even if he dies, he will bite off a piece of Li Muzhi's flesh.

Lujia Village, Wangjia ...... Manure tanks.

Lu Yan continued to face the manure tank in a daze, and all kinds of materials flew in turn in front of him, but many of them were teleported over.

Neither natural materials nor easy-to-make tools can transport biogas for a long time, either penetrating or easily damaged.

In the end, Lu Yan was almost stunned, and even in the face of the septic tank, he couldn't feel the smell inside.

"No, I always feel that my thinking has entered a misunderstanding, if there are really simple, cheap and stable materials in nature, it is impossible to drag on until now without discovering them, and my advantages cannot be brought into play at all. ”

"It is impossible for this world to appear without discovering it in the previous life, and the facts have long proved that this is a line of thought. ”

The more Lu Yan thought about it, the more he felt that it was wrong, and decisively gave up the test, I am afraid that if it continues like this, there may not be results in a hundred years.

I was very depressed, and it seemed that Edison's chicken soup with electric lights that relied on diligence and patience was not delicious.

Although this is the world of Dao Dharma manifestation, it is in the same vein as the previous life, and it is impossible for a particularly anti-heaven material to appear without being discovered.

"Since it is a world of Dao Dharma manifestation, the best way is to solve the problem through divine power. ”

Lu Yan muttered, unconsciously picking out a bamboo pole from the scrapped materials piled up next to him.

The reason for giving up the bamboo pole came to mind, there was a knot in the middle, and there were gaps in the bamboo body, and the loss in the process of biogas transmission was too large.

The divine power is instilled into it, and all the bamboo joints inside are opened, and then the divine power penetrates into the bamboo body, and the biogas is instilled into it unimpeded.

"I see, it's so simple!"

Lu Yan couldn't believe it, the divine power was really omnipotent, and then he took a piece of iron, melted it in his hand and turned it into a switch set on the mouth of the bamboo pole, and the other piece of iron turned into a triangular bracket.

Such a simple biogas stove was built.

The only difficulty is that it needs to consume divine power, and ordinary people naturally cannot use it.

However, the success of the first step made Lu Yan's thinking instantly broaden, since ordinary people can't use divine power, what about his temple blessing?

Pray from the temple, and then obtain the permission to borrow divine power through prayer, and then transform the materials of believers, so as to form a complete closed loop.

It still can't be promoted here, don't look at it as a small spell, but if it is promoted to the whole world, the consumption of divine power is too terrifying.

Unless he can recoup his costs with biogas.

Thinking of this, Lu Yan's eyes lit up, about promoting his experience, the world may not pay attention to it, if it is a painstaking get, it will be cherished by nature.

"If you want to use biogas, you must offer it to me, and the temple can only build a biogas digester for the believers of the toilet god, and the custom of burning incense and offering on the 15th day of the first month of every month must also be promoted. ”

Extending along this line of thought, the smile on Lu Yan's face became thicker and thicker, and if he continued to promote the biogas digester in this way, not only would it not consume divine power, but it would bring countless believers and incense in his dream.

The next step is to build a biogas digester yourself and test your ideas.

"Xiaozhu A little girl used to go up the mountain to chop firewood, and when she came back, she had to chop firewood, which was quite hard, so start with you. ”

Lu Yan thought with a smile and looked at Xiaozhu's father next to the septic tank.

Hehe smiled: "It should be okay to borrow your dung for use, right?"

After saying that, he started to act, moving the septic tank to the back of the Lu God Temple, and a steamed bun-shaped biogas tank soon appeared, and the divine power spread to the bamboo poles all the way to the kitchen.

Soon a biogas stove appeared, an iron pot flew to the stove, the fire was automatically ignited, and a biogas digester and biogas stove were completed.

"Perfect"

Lu Yan looked at the masterpiece in front of him and was very satisfied, and he really planned to appreciate his results, but suddenly felt that the sky was different.

Looking up, I saw a huge golden cloud of merit descending rapidly.
