Sanyuzhu walked through the city of Jakarta in flames, barely mad.

Now the whole city of Jakarta is full of burning buildings, and the captured Dutch soldiers pointed out the important buildings in the city one by one, and without exception, all of them were burned in flames.

"These dog mongrels!" Sanyu Zhu said angrily: "Go and inform the fleet to go to Bull City, you must not let these Dutch escape from Bull City to Calcutta." ”

Receiving the order, the herald quickly rushed to the coast, where he used the flag to inform Thunder of the situation in the city.

"These Europeans still have some skills." After reading the meaning of the flag, Yue Yun said with a calm face.

Thunder's face was rather ugly, and according to the Empire's reward system for foreign wars, the spoils of war were a very important indicator.

Now they get a burned and messy city, and they suffer a big loss.

And although this attack was as successful as ever, the number of soldiers they lost was increased by multiple compared to the previous battles.

The deep trenches also provided a lot of protection for the Dutch soldiers.

"One thousand and three casualties, the soldiers can't share a copper plate, and my commander will be in vain, General Yue, please be sure to lead us to Bull City in advance, I must not let go of this group of bastards." Lei Ming said.

Although he was accustomed to seeing death on the battlefield, he was really uncomfortable with so many casualties, and now he was only fighting against 20,000 Dutch and miscellaneous natives, and if he faced the battlefield of Calcutta, the casualty figure would probably double.

Yue Yun could feel the thunderous rage, and it was obvious that the Dutch had provoked him.

"That's no problem, with the speed of an ironclad ship, I'm sure we'll be able to get to Bull City ahead of them." Yue Yun said.

Boer was a straight line distance for the Dutch army on land, but for the navy they needed to make a big detour to reach it, after all, the coastline was not straight, and at the speed of a sail warship, they might not be able to reach it in advance.

But the ironclad ship will definitely be able to accomplish this task when sailing at full strength.

"Thank you." Lei Ming said through gritted teeth.

……

Qingzhou.

After the hand-cranked telephones were officially connected, the Telecommunications Department began to install telephones in Qingzhou for the official offices of the Imperial Palace and the Outer Palace.

According to the requirements of the Cabinet, in the former Qingzhou, telephone communication between various departments of the imperial court should be realized to improve the efficiency of handling government affairs.

While the telephone made significant progress, Lin Wentao's mechanical research institute also came with good news.

"Your Majesty, this is the first prototype car we made using an internal combustion engine."

Lin Wentao in the machinery factory pointed to the classic car in front of him with an excited expression, since the internal combustion engine technology has matured, they have launched various applications of the internal combustion engine.

In addition to diesel engines for drilling, they put the application of internal combustion engines to sports machinery on the agenda in accordance with the requirements of the five-year plan.

So they first set their sights on the animal-powered harvesters that were being used in the Empire, and according to the institutional drawings, they gave these agricultural machines a heart for an internal combustion engine.

After the application of the harvester was expanded, they built a manned car according to the drawings provided by Xiao Ming, which was the classic car in front of them.

Xiao Ming walked to the classic car, the shape of this classic car is basically similar to the shape of the first generation of cars in Europe in the 19th century.

In fact, it's not that he doesn't understand a more perfect shape, but with the current industrial technology, Qingzhou's industry is not able to manufacture a car shell with modern craftsmanship.

So by all accounts, he honestly used the old-fashioned Beetle shell.

"How fast can this car go?" Xiao Ming asked with a little excitement, after so many years, he finally ushered in the embarrassment of not needing to ride a horse and going out in a carriage.

On the other hand, with a car, his safety when going out will be greatly improved.

"Back to the emperor, the speed of this car has reached sixty kilometers per hour." Lin Wentao said.

"Sixty kilometers?" Xiao Ming had a heavy smile on his face, he was already very satisfied with this speed, after all, the speed of the world's first car at that time was only one hour and fifteen kilometers per hour.

However, the difference is that Xiao Ming gave Lin Wentao a mature internal combustion engine technology, and he also used purified gasoline, so this car exploded the first car in all aspects and reached the level of an improved car.

Qian Dafu said with a smile: "At a speed of sixty per hour, wouldn't you be able to run more than a thousand kilometers on this day?" ”

"That's natural, but you need to bring enough fuel, and the Empire probably can't afford to use gasoline like that at the moment." Lin Wentao's words were filled with regret.

So far, no progress has been made in the drilling of oil wells, and the drilling has been more difficult than anyone expected.

There is no oil field, which means that the car is also fake, which is the reason why Lin Wentao sighed.

Xiao Ming naturally understood what Lin Wentao meant, he still overestimated the current technical level of the empire, and the Daqing Oilfield was already difficult to exploit, so it was normal that there would be no progress for such a long time.

According to records, during World War II, Japan also tried to find the Daqing oil field, but drilling stopped after reaching about 800 meters, because Japan did not have the technology to drill deeper rock formations at that time.

The real depth of Daqing Oilfield is about 1,300, so whether the oil can be successfully recovered or not is essentially a drilling technology.

The fundamental of drilling technology is the problem of drill bits, now with diesel engines, the power is solved, and the strength of the drill bit must not reach such a deep rock layer.

After all, drilling oil wells requires a special oil drill bit, and he can give a drill bit design drawing, but the material problem still needs to be experimented with many parties.

So he is a little helpless about the current problem, because no one is sure when this oil field will be successfully exploited.

If the oil field cannot be used because of technical problems, he can only find a way from overseas, after all, his drilling technology cannot conquer Daqing, which is thousands of meters deep, but it is still very simple to exploit oil wells on the land of the Middle East.

The most important thing is that after mastering the mature ironclad technology, the cost of sea transportation is greatly reduced, and it is not very far from the Middle East to the empire at the speed of ironclads, and the cost of transporting oil is very low.

"At present, the empire is fighting a war in the South Seas, and if it goes well, the route to Persia and the Ottoman Empire will be completely opened, and then the empire will be able to establish diplomatic relations with Persia and the Ottomans and buy their oil cheaply, so that the machinery equipped with the internal combustion engine will be able to run." Xiao Ming said, and at the same time, he became more and more determined to monopolize the idea of oil.

It was really uncomfortable to be poor in oil, and in addition to Persia and the Ottomans, he had to completely occupy Siberia, after all, there was also a big oil field there.
