Although Tang Ming's words were said very tactfully, Fang Xiaoru's face still changed slightly, and his heart was still difficult to accept Tang Ming's change at the moment. It was as if at this moment, he had become a stranger to him, and he had completely failed to see the politeness and respect for his elders before, and some were just blunt and indifferent.

Fortunately, Fang Xiaoru is not an ordinary person, the cultivation of Great Confucianism has not made him lose his mind, and he still knows how to think calmly after being in the imperial court for many years. His anxious questioning just now was indeed inconsiderate, in private, he and Tang Ming could talk about seniority, but in public, Tang Ming, as a marquis, shouldered the responsibility of managing nearly 10,000 people on the island, and the respect and etiquette that should be there is indeed indispensable.

Moreover, he Fang Xiaoru only heard about it, and as for the real reason inside, he hadn't figured it out yet, so he hurriedly came to question Yu Tangming, and at this point, Fang Xiaoru suddenly felt ashamed. Rarely, his old face was slightly red, with a little embarrassment, and he said goodbye to Tang Ming.

Fang Xiaoru is not old enough to be confused, which makes Tang Ming get a little comfort, as long as he can still be sensible and don't rely on the old and sell the old at every turn, then Fang Xiaoru, the great Confucian, can still play a certain auxiliary role in Tang Ming's rule.

Fang Xiaoru left, no one here dared to come out to make trouble, and Tang Ming had already found the talent he wanted, so he naturally dispersed everyone. With a smile, he took this person to his residence and talked behind closed doors. Such a mysterious practice can't help but make people suspicious, especially Tang Ming's anxious appearance at the moment, which made the middle-aged man from a craftsman cross his hands and hug his chest.

The thought that popped up in his mind was: "This Hou Ye won't have Longyang, in broad daylight, he actually called himself to his residence, and closed the door to talk to him about something." ”

The more the middle-aged craftsman looked at Tang Ming, the more he felt that something was wrong, but fortunately, Tang Ming did not do what he imagined in his mind. Instead, he put the lighter in his hand on the table, pointed to the liquid inside, and said with a smile: "These things that look like water in them are called biogas, not some kind of fierce fire oil that we usually use to light lamps." I came to you to see if I could make a few things for Master Hou and me? ”

The middle-aged man breathed a sigh of relief and secretly scolded himself for being a bastard, and actually thought of Hou Ye as a good person in Longyang, but fortunately, Hou Ye did not find out his dirty thoughts, otherwise his little life would definitely be lost. Honestly saluted Tang Ming, the middle-aged man lowered his head and said: "Back to the Hou Ye, the villain's name is Xiao Shu, his hometown is from Shandong, and his ancestors have been craftsmen for several generations. Since the death of his father, the villain has ******** studied the handicraft of the family, although it has improved a little, but the villain has also delayed a lot of time, and now he has reached the age of 30, and he has not married ....... ”

Xiao said that he hesitated at this point, not knowing whether to say the next words or not. Seeing his hesitant look, Tang Ming smiled slightly, and encouraged: "Xiao vulgar, if you have something to say, as long as Master Hou and I can do it, I will definitely make decisions for you." ”

"Little thank you Hou Ye for your love, unfilial piety is the first thing, I am the only one left in the family, and the villain is so poor that he can't get a wife, the villain dares to ask Hou Ye to choose a spouse for the villain, with all his heart. In the future, the villain will be regarded as a cow and a horse to repay the great kindness of the Hou Ye. Xiao Shu's heart-wrenching words really touched the weakness of Tang Ming's heart.

Unconsciously reminded him of the pain points in his heart, and the family members of later generations don't know how they are doing now, and these thoughts that were finally covered up came to mind like a spring at this moment.

After looking at Xiao Shu and thinking about what happened to him, Tang Ming finally nodded and agreed. The worries in Xiao Shi's heart have gone, and people have become much more agile. Tang Ming used a brush to draw a few diagrams of pipelines used to transport biogas.

After handing it to Xiao Shu to watch, he explained the unknown points for him, and ordered him to build it immediately. These pipes and fittings, including the stove used for combustion, are not really technical. After Xiao Shu understood the structure clearly, he also admitted to Tang Ming that there was no problem, but he just needed a little more time to make the mold.

Hearing that there was no problem, Tang Ming also let go of the worries in his heart, in fact, the drawings he gave Xiao Shu just now had already lost many unnecessary functions. Even the material of the pipe, Tang Ming asked Xiao Shu to use copper if he allowed it. The same copper is used for the stove for the fire, and only in this way can these things be brought out as quickly as possible.

As soon as things were done here, Tang Ming immediately rushed to the place where the pit was dug again. Nangong Quan's efficiency was indeed good, at the moment when Tang Ming left, he actually called more than two hundred people, and he dug a big pit five meters wide and four meters deep in this short period of time.

Tang Ming himself had never made a biogas digester, and he didn't know the real specifications, and besides, he just wanted to test it now, so such a big pit was enough. He stopped all the workers, called aside a few recognized master masons, and drew the shape of the digester that still had an impression in his mind with a tree branch.

In fact, the shape of the biogas digester doesn't matter much, as long as the bottom is big and the top is small, Tang Ming didn't put much effort into it. His biggest concern at the moment is that the material used to build the wall must be as strong as cement, in addition to being strong enough.

It was not realistic to come and burn cement now, so Tang Ming told his concerns to a few mason masters present.

Several people laughed at the same time when they heard this, and when it came to the solid mud material, in ancient times, it was the glutinous rice mud used to build the city wall. Tang Ming is a fan of the authorities, and after being reminded by the mud master, he naturally suddenly came to his senses.

There were no ready-made bricks on the island, so the mud master replaced them with small stones, and two hundred people built a small digester, although many materials needed to be taken on the spot, but in the evening, a perfect digester was completed.

Tang Ming personally went down to check, and the effect was indeed satisfactory to him. In fact, the ancient construction technology is not worse than that of later generations, although it takes a little time and effort, but in terms of quality, this biogas digester is definitely more than a hundred times better than those tofu slag projects that cut corners in later generations.

Everything was ready and only needed to wait for the experiment a few days later, in order to prevent accidents, Tang Ming also deliberately left more than 20 guards on duty in turn. It was even more decreed that no unrelated personnel should approach this place, and those who dared to disobey would be killed.

The first forbidden place on Weihai Island was born, and it later became one of Tang Ming's many great contributions.
