The former glory is gone, and Ji Gang has been transferred by the emperor away from Nanjing, the center of power, even if he really has a way to counterattack Dongchang. Li Ba didn't have time to spend time with him, so he killed a few of the old eunuch's bodyguards on Weihai Island, and Li Ba had already thought of this way out.

Although Tang Ming was a little poor, he was absolutely free to save his life, even if Li Xing found out afterwards that it was the person who killed him himself. There is absolutely no way to reach out to Tang Ming's fiefdom, and the combination of various reasons is enough for Li Ba to choose how he should go in the future.

This time, Tang Ming was ambushed by pirates, but not only did he not lose anything, but he defeated more than a dozen pirate forces that had been entrenched overseas for many years. With such a huge credit, Zhu Di, the emperor, will definitely not ignore it, even if Tang Ming will not be promoted to a knighthood because of this, a verbal or a little material reward is absolutely indispensable.

To reward Tang Ming, someone naturally has to announce the decree, this is Li Ba's opportunity, if he wants to become the person who will pass the decree, Li Ba must find someone else now except Zheng He, who thinks there is no one else. With the letter written for him by Tang Ming in his arms, Li Ba took advantage of the opportunity that he didn't have to go to work now, and left the palace and went straight to the treasure shipyard.

A few days later, Tang Ming, who was far away on Weihai Island, did not wait for any news about the emperor, and no ships arrived during this period. Tang Ming, who had never taken this matter to heart, seemed to have forgotten about it, and today his long-awaited biogas digester finally ushered in the day of trial.

The pipe made of copper was very satisfied after Tang Ming's acceptance, and Tang Ming did not have any concerns about Xiao Shi's craftsmanship. The only thing that made him dissatisfied was that there was not much copper on the island, and in order to build these interfaces and pipelines, Tang Ming searched all the ships, even the pirate ships.

Tang Ming designated the area around the digester as a forbidden place, but today he allowed anyone on the island to come, and as soon as the news spread, this small high ground was soon overcrowded. Everyone is curious about what trick the little marquis is going to change, and the lighter that he performed in front of the craftsman last time has been spread on the island.

In fact, everyone is not amazed by Hou Ye's clever tricks, to put it bluntly, the lighter is similar to the fire fold used by large families, and it is really unnecessary to be amazed by these. What everyone praised was that Tang Ming, as a marquis, was willing to let go of his high status and perform tricks for their mud-legged craftsmen. Such an entertaining spirit and approachable Hou Ye will naturally be praised and supported by everyone.

The biogas digester only lasted three days of fermentation, and the time was shorter, so Tang Ming specially ordered someone to kill a few dying old cows and fill them in the biogas digester just in case. In this way, the emission of biogas will be much faster.

Tang Ming unscrewed the main valve, a hissing sound sounded, he understood that this was biogas, and walked to the stove four meters away, a huge stove about one meter long, the shape was exactly the same as those explosive stoves in the hotel kitchen, but it was much larger than that.

Unscrewed the small valve for ignition, and in the hissing sound, an unpleasant smell suddenly emanated. Frowning, Tang Ming couldn't help but sigh in his heart: "Nima, there is no purifier in the future, the smell of this biogas is really unpleasant. In addition, once this thing is not done well, it will explode every minute, and you have to find a way to train special operators. ”

Quickly hold back his breath, just for a moment, Tang Ming already felt his head slightly dizzy. He knew that this was a sign of poisoning, so he quickly took out his lighter, checked the size of the valve again, and felt that it was okay before igniting.

Once or twice, Tang Ming didn't light it, which made him a little puzzled, but fortunately, when he played it for the third time, he finally lit it. The smile that had not been seen for a long time jumped on his face again, and until this moment, Tang Ming's heart that had been carrying it could finally relax a little.

When the fire was lit, the unpleasant smell unique to the biogas disappeared, and the valve of the jet was adjusted wider again, Tang Ming opened the big valve on the other side, and the huge stove spewed out the methane violently, and as soon as it encountered the fire of the ignition nozzle, it immediately stringed out flames more than 50 centimeters high.

The fierce eruption of flames caused everyone present to burst into exclamations, they really didn't understand how Hou Ye had managed to do such a magical point. Using the dung of some cows and horses and the corpses of a few dead and rotten cows, such a large fire was burned.

When people deal with unknown things, they always have curiosity and fear in their hearts, but it is Tang Ming, the ruler of Weihai Island, who makes this thing, and everyone present only worships Tang Ming without any bad negative thoughts.

The iron still needs to be struck while it is hot, Tang Ming took advantage of the strong curiosity of everyone present, and explained: "This thing is biogas, which can be used to replace the firewood we usually use, and it is very convenient to boil water and cook things." Just like I just demonstrated, just unscrew the valve a little bit. ”

"But!" Tang Ming glanced around the crowd, the expression on his face became very serious, and he said in a deep voice.

"It's convenient, but as you can see, it's the dung of cows and horses and the poisonous gas from the rotting carcasses of dead cows. Once you inhale too much of this unburned methane, you get poisoned and die, and that's a matter of minutes. ”

"Also, you have to learn to operate this thing in a standardized manner, otherwise it is easy to cause an explosion, a biogas digester of this size, once an explosion occurs, the power can withstand the simultaneous bombardment of ten cannons."

Tang Ming wasn't worried about whether he would exaggerate or not, anyway, no one had ever seen the explosion of the biogas digester now, so in order for them to remember this tightly, it was necessary to say that it was too big.

As soon as Tang Ming's words fell, the crowd of onlookers shouted in unison, and they all took two steps back. If this biogas is really as powerful as Tang Ming said, then they are so close, wouldn't it be possible to be affected at any time.

When they all took two steps back and reacted, they remembered that Hou Ye was the closest person. Hou Ye is Jin Guiming, he is not afraid of death, and they are all far away if they are frightened like this.

Including Xiao Shu, he also unconsciously took a few steps back, with a little embarrassed look on his face, but he pretended to be calm and said: "May I ask Master Hou, what kind of biogas is so dangerous." And this thing can only be used to light the fire, and nothing else is of any use, so it seems not worth it to take such a big risk for the sake of making it easier to burn the fire? ”

Xiao Shi's words can be said to express the doubts in the hearts of everyone present, from ancient times to the present, everyone uses dry wood or coal to burn the fire. You don't need something as dangerous as biogas, and it's not worth the risk of burning a fire.
