(Yesterday 7 tips, a total of 361 times, 72.2 more.) A total of 245 monthly passes were issued, and 12.25 more. Yesterday's increase was ×1, the cumulative increase was ×9, and the accumulated debt owed: 75.45 more...... (Yesterday's plus more miscalculation))

The hot air balloon flew at a high altitude for more than two hours before Murong Shan began to control the hot air balloon to land slowly.

However, there are many people around who are excited and want to experience it.

People were so enthusiastic that Xiaozhu Xiaoyue was a little frightened and had to ask Zhang Hao. Zhang Hao nodded, but after the test just now, the hot air balloon can only carry five people at a time, and one person needs to be left to control the hot air balloon, so it can only carry four passengers at a time.

Zhang Hao looked at the crowd scrambling and smiled faintly. The hot air balloon was originally intended for public commercial use.

In this world of cultivation, the military value of hot air balloons is difficult to reflect for the time being, the speed is slow, and the defense is almost non-existent. In contrast, the commercial prospects are a little greater.

Of course, Zhang Hao doesn't mind selling hot air balloons to various countries and using them for military purposes - as long as you buy them, we can produce them, and we will also take care of the training.

Zhang Hao watched it for a while and left with Zhou Xueyao, there are more things to do. Since the hot air balloon has succeeded, Zhang Hao doesn't need to worry about the airship or anything next. The internal combustion engine is also in the final testing phase, and the power system of the airship is also easy to solve.

And even if there is no internal combustion engine, the speed of the airship is already slow, the air resistance is relatively small, and it can be propelled by spells or formations - maybe faster than the internal combustion engine.

Because of the above reasons, Zhang Hao was not prepared to use the hot air balloon as military equipment. However, the original plan of hot air balloon research was to explore the high altitude, and the aura above the altitude of 20,000 zhang began to thin out.

Zhang Hao and the elites of Dayang Group are eager to understand - this is also one of the priorities of the next step. Only by figuring out what the aura is going on can we better practice, especially better understand what kind of realm the transformation period is and what kind of existence the immortal qi is!

After Zhang Hao and Zhou Xueyao went back, Zhou Xueyao went straight to his research base. Now, Fairy Zhou has built the framework of the periodic table - perhaps a little imperfect, Zhou Xueyao is even more eager to know what this world is made of.

And the new field of chemistry, combined with her own alchemy knowledge, etc., also made Zhou Xueyao more and more excited, and she faintly felt that she seemed to have touched the core of this world.

Scientific research, especially the kind that advances rapidly and keeps getting closer to the source, is addictive!

The exploration of the origin of the world, the pursuit of truth, is the most intoxicating.

Zhang Hao inspected the production base, port, etc., and everything satisfied Zhang Hao.

Today's port is already prosperous, although the Xuanzhen Sect lost four steel warships, and the Ocean Group sold two more to the country of Canglan, but now there are still seven steel warships coming and going in the port.

However, in the past three months, because of the need to build a new dock and so on, the Ocean Group has not produced new warships. However, in the dock, there are already five 10,000-ton (Iron Duke class) warships, which have entered the outfitting stage, and it is expected that at most a month, the Ocean Group will add five more steel warships.

However, these five steel battleships have already been booked. Two ships of Dayang Group, two ships of Xuanzhenjiao, and one ship of Liu Xinyu.

In addition, there is a 20,000-ton battleship, which is in production.

Liu Xinyu paid with the wealth he had scavenged from various countries, while the Xuanzhen Sect was at a loss, and the three steel warships that had already been lost could only be paid out of his own pocket. In other words, the 10 warships originally booked by the Xuanzhen Sect are now 7 places left.

Three months have passed, and the Xuanzhen Sect is still in distress - the impact of what happened at the beginning is so great that now technology is blooming everywhere, and the Loose Sect has it. The advantage that suddenly appeared in the Xuanzhen Sect before suddenly disappeared again.

But this has nothing to do with Zhang Hao, at least now Zhang Hao doesn't care about these things. Anyway, the benefits of belonging to the Ocean Group have already been obtained.

Recently, there has been a big explosion of industry and commerce in the West of the whole fertile continent, but if you want to develop industry and commerce rapidly, you need to buy machinery and equipment, especially machine tools, from the Ocean Group. Although it is only a simple machine, it is not easy to make a good one. In particular, the steam turbine driven by the spirit stone, which must be used for machine tools, is still only produced by Dayang Group.

As a result, when industry and commerce broke out everywhere, Dayang Group's orders were also a bit reported, and orders for key equipment such as machine tools were scheduled until the end of the year. Even so, orders are still increasing.

In particular, the standards of the Ocean Group are also spreading rapidly.

The Ocean Group cultivated the market with a technology leak. Perhaps someone has already discovered the conspiracy of the Ocean Group, but it is no longer useful.

The technology has leaked, the market has matured, and it's too late to say anything.

After Zhang Hao inspected the port, he was ready to leave. But at this moment, I saw a few warships floating in the sea in the distance, in the south.

To be exact, there are three, and Zhang Hao can see at a glance that they are from the Ocean Group.

Zhang Hao suddenly frowned - the battleship only sailed south 8 days ago, and according to the past situation, it would take at least 20 days to return. Why did you come back so early?

And when they set off, there were four warships, and when they came back, there were only three left. The smallest, the battleship Zhiyuan, with a displacement of four thousand tons, disappeared.

A master flew from the battleship, and soon came to the port and saw Zhang Hao. Zhang Hao also saw each other and knew each other (Zhang Hao knew almost all the Yuan infancy of Dayang Group). Looking at the other party's hurried and embarrassed appearance, Zhang Hao frowned, "Ma Rong, what's the matter?"

Ma Rong opened his mouth, looked around, and whispered, "We met the mirage again." This time, the mirage actually gathered five, all of them in the god transformation stage. The Zhiyuan sank.

We almost ran out of shells. But the mirages have learned wisely, and they are hidden in the deep sea, and we can hardly do anything about it. ”

Zhang Hao's pupils contracted: "The worry finally happened." How's the people?"

Zhang Hao did not ask the battleship, but the person. Ma Rong's eyes flashed with warmth, as the Yuan Infant Period, one of the big reasons why they were willing to serve under Zhang Hao was that Zhang Hao did have an admirable side. When an accident happens, we don't ask about the damage, etc., but how the person is.

It seems like a simple thing, but the impact on the subordinates is immeasurable.

Ma Rong continued to whisper: "A dozen ordinary sailors have been lost. The rest is fine. ”

Zhang Hao sighed: "Don't make a noise about this matter for the time being, there is no need to create tension." You let everyone dock first, let everyone rest first.

Wait another month or so, wait for our new ships to be launched, and kill them!"

In the past, Zhang Hao, Dayang Group and Mirage have always maintained a tacit understanding - not to attack each other. Unexpectedly, after a few months, these beasts couldn't help it.

After a pause, Zhang Hao asked again, "What about Fu Yun who accompanied the ship this time?"

"A battleship was whipped by a mirage, and it leaked badly, and the keel on the left side was twisted, all supported by Fu Yun's predecessors. The other two warships were also damaged. ”

Zhang Hao took a deep breath, "Let the battleship go directly to the dock, don't dock." ”

After a while, the shore was still noisy. Although Zhang Hao didn't want to make a noise, the three battleships were so big that they couldn't hide it at all. Especially when you are closer, you can even see the ruined superstructure and the sunken armor side of the ship.

At first glance, there was a big war. And this kind of battle and explosion is noticeably different. Someone shouted on the spot: I have met the sea monster!

Some of the family members of the crew members were even more tense.

The battleship did not dock and went directly to the dock. The newly expanded dock is large, with five large bays – 30,000 tonnes and five small bays – 10,000 tonnes.

Zhang Hao personally inspected the situation of the battleship. The first battleship was almost a quarter sunken in the middle and left side, and the seven keels on the bottom of the ship were broken one and two twisted on the left side. Fortunately, the main keel is fine.

On the outside of the battleship, traces of a mirage's tail can also be seen, with the mark of scales. Zhang Hao looked at it and secretly said to himself, these sea monsters were really powerful and terrifying. What is the hardness of steel, Zhang Hao knows very well, can leave such a mark on steel, this mirage...... I'm afraid it's not the realm of the late stage of the gods, right?

Fu Yun finally came out, his face was a little pale, "The mirage that attacked us this time is about one hundred and fifty meters long, and it can only be contained by a large number of depth charge attacks. ”

Zhang Hao looked at the battleship, and his tone was very calm: "Let's rest for a month first, and try to restore this matter as much as possible." Next time, we're going to slay the dragon!"
