This is Mao Wenlong's biggest feeling at present, people are like this, sometimes they will always stubbornly think that their ideas are right, and they can't listen to anyone's persuasion.

Staying in the Ministry of Works, he thought that he would be able to concentrate on building a steam engine warship from now on. However, Mao Wenlong soon discovered that things were not as smooth as he thought.

After the natural disaster passed, there was a man-made disaster in the Ming Dynasty, and those unfavorable rumors stopped. But there are still some ill-intentioned guys who are operating frequently in the dark, taking advantage of this natural disaster to expand their power.

The dark guard camp was already anxious, and they hurriedly folded one after another, annoying Mao Wenlong enough. In fact, these ill-intentioned forces are very small, and they can be directly ignored when they are taken out alone. However, these forces have tenacious vitality, like weeds on the grassland, and after the fire, they will be quickly reborn.

These ill-intentioned forces have shifted from the open to the dark, putting more pressure on the reconnaissance of the secret guards. Haoda is going crazy, and every day he pesters Mao Wenlong with red eyes to ask for a solution.

But how can such a thing be effective overnight, Mao Wenlong patted the vast shoulder and comforted: "You still have to eat one bite at a time, and you can't come in a hurry." As long as there is no big mess, let those with bad intentions bounce for a while, and wait until the dark guard has full control of their whereabouts before acting. ”

Haoda rolled his eyes, and said urgently with red eyes: "Chief soldier, the problem is that you can't rush now!" The rat-like creatures are savvy, and the Dark Guard will have to pay more than twice as much to control their whereabouts as usual. Moreover, these forces were broken into pieces and scattered in the south and north of the Ming Dynasty, and they were drilled at the slightest loophole. Every time the secret guard heard the news, it was too late. Now that bad news comes every day, my subordinates are afraid that if they don't find a way to solve it, it will be detrimental to the foundation of the Ming Dynasty. ”

Mao Wenlong's expression was as usual, and he said indifferently: "The little thief doesn't have this ability, and the Ming Dynasty today is not as good as before." Those bad guys can only disgust us for a while, and if they really want to say that they can do it, it is completely impossible. Needless to say, do as I say, let the dark guard stabilize the morale of the army, and spy on the details of those guys. It's never too late to wait until you're in control of their whereabouts. ”

waved away, but Mao Wenlong was not as calm as just now, and at this moment he still held an urgent report in his hand. It was an urgent report that had been delivered just before the vast arrival.

Adou talked about the incident over there in the emergency report, saying that the sea was starting to be uneven again. Xiangjiang Island and the South China Sea began to be uneven again, and countless islands began to spring up like mushrooms after a rain. These pirates seem to know a lot about the Dongjiang Naval Division, and every time they make a mistake there, they will be attacked by a group.

After three times, Adou also began to be a little overwhelmed, and had no choice but to ask Mao Wenlong to send troops to support. The vast sea needs more navies to ensure safety and remove these hidden dangers.

It's a pity that Mao Wenlong still has an army there for Adou to drive, and the Ming Navy has only been built for less than five years.

Under internal and external troubles, Mao Wenlong no longer had the heart to build any steam engine warships. Put the matter down and leave it to those professionals to do, Mao Wenlong went to find Hong Chengchou to discuss with Adou's urgent report.

The old man is very leisurely now, and since the rescue is over, the academy has returned to its usual tranquility. Xin Wei, the dean, does everything himself, and he, Hong Chengchou, can only give him ideas when Xin Wei can't make up his mind or is confused.

Hong Chengchou, who was idle, began to be interested in those strange inventions in the academy. Those who were previously known as non-professional crafts, after playing their role, Hong Chengchou completely changed his original paranoid views.

When Mao Wenlong found Hong Chengchou, the old man was fiddling with some copper pipes that were very smooth. These pipes are used in the biogas digester to connect the biogas.

Weihaiwei is a place near the sea, and there are no mountains here and there is not so much wood to cut and burn. The emergence of this biogas has brought great convenience to the college, not only does it not have so much pollution, but also solves the problem of fire.

The entire academy has now completely used biogas, but unfortunately it is not possible to apply biogas to the whole of Weihaiwei. Because copper pipes are used, in order to popularize biogas, a large amount of copper ore will inevitably be needed for forging.

Judging from the amount of copper ore currently mined in the Ming Dynasty, it is far from meeting the demand. Hong Chengchou was very concerned about this beneficial livelihood demand, and at the behest of those craftsmen, Hong Chengchou was ready to propose to Mao Wenlong to bring copper ore from the sea.

said Cao Cao, Cao Cao arrived, Hong Chengchou was just about to go to find Mao Wenlong, but he didn't think that Mao Wenlong would take the initiative to find him. It's just that Mao Wenlong's face is wrong, and his gloomy face means that Mao Wenlong is unhappy at the moment.

Holding back the urgent needs in his heart, Hong Chengchou asked curiously: "Is there something on the heart of the chief soldier?" ”

Mao Wenlong sat sullenly opposite Hong Chengchou and said: "The Ming Dynasty has come through ups and downs and experienced many ups and downs. I thought that now was the beginning of a prosperous era, but unexpectedly, natural disasters and man-made disasters continued, alas......"

A long sigh expressed Mao Wenlong's helplessness, but Hong Chengchou rolled his eyes, thinking that Mao Wenlong was bothering something? It turned out that he was just coming to complain to himself. Without so many concerns, Hong Chengchou was not interested in listening to Mao Wenlong's complaints, he said with a serious face: "Chief soldier, you can't rush those things, it's better to put them aside." If there are some urgent solutions in front of them, the general soldiers may wish to sum them up. ”

Mao Wenlong frowned, now he was most afraid of hearing any more bad news. Looking at Hong Chengchou's expression, it seems that he has something to discuss with himself!

"What do you want to discuss, sir?" Mao Wenlong sat up straight and became serious.

Seeing that the cold winter is coming, only the academy in Weihaiwei uses biogas, and the people in other places are still having headaches for the firewood for the winter. The old man thought that if this biogas could be popularized, it would definitely benefit more than the north. Hong Chengchou talked with admiration.

"Spreading the ...... biogas"

Mao Wenlong was stunned for a moment, then shrugged his shoulders and said with a wry smile: "Sir, don't you know that the application of biogas is currently inseparable from copper pipes." However, the current copper mining in the Ming Dynasty was completely insufficient to support the popularization of biogas. ”

"These old men naturally understand, so they discussed with the general soldier to see if they could transport copper ore to Daming from other places on the sea. Wouldn't that solve the problem of our lack of copper mines? Hong Chengchou said as a matter of course.
