"Help?" Zhang Hao received the news from space, and when he looked closely, he suddenly couldn't cry or laugh, the landing module was blown away by the strong wind, and the corner of Zhang Hao's mouth twitched: You can't laugh, because the landing module of the Ocean Group was also blown away.

However, compared to the Hunter and its landing module, the landing module of the Ocean Group is a one-time one, and there is no need to think about returning later. Moreover, Dayang Group dispatches robots, so there is no need to worry about life and death.

But apparently, the crew of the Hunter is different, and they have to return.

After thinking about it, Zhang Hao said: "Let the robot find their location first and establish communication contact." Let's look at the actual situation. ”

"The cost ......," the secretary asked cautiously.

"Tell Dugu Junjie that if it's just a simple positioning, we'll earn favors. But if you need our help...... It depends, and the bill for our construction and launch of the Venus exploration rocket can be sent to them at most. ”

Secretary:......

Zhang Hao patted the secretary on the shoulder, "You have to think like this, because of this rescue, we have delayed our plan to explore Venus, and it has also affected the pace of the development of Tianyuan Star civilization." They have to make amends!"

Secretary:...... I was even more speechless.

As Bai Fengshan, who just graduated this year and was lucky to break through thousands of troops and was finally selected by Zhang Hao as his secretary, he was under tremendous pressure while enjoying the envy of others.

Every year, Beidou Academy will select the best one from among the graduates to become Zhang Hao's secretary for a period of one year, and then arrange the corresponding position according to performance, ability, and Boss Zhang's personal preferences.

Because of this alone, it is enough to make Beidou University the most well-known institution in the world. Not to mention that the teaching ability of Beidou Academy itself is also the best.

After a year, someone will be able to become a governor directly, someone will enter a scientific research institution to become a project leader, and of course someone will not be reused.

For example, the senior brother of the previous session is now only in charge of the World Congress Center; by the way, this World Congress Center is the old one, and in the old land of the Ocean Group, it is the small land in the west of the Fertile Earth Continent.

It is said that this senior brother was caught by Mr. Zhang for accepting bribes, which became the biggest joke in the history of Beidou Academy.

However, after a long time of contact, you will find that in fact, Mr. Zhang ...... For example, this time, this is obviously to pass on the financial pressure of the Dayang Group's research on the Venus exploration rocket.

No wonder Zhang Hao must have insisted on launching the Hunter rocket one after the other, it turned out that he was waiting for the other party here.

Also, the first time to explore Venus, it is directly a manned landing, and it is strange if there is no problem!

Bai Fengshan walked out and thought about it, and when he came to his small office, he immediately sent Zhang Hao's relevant reply to Dugu Junjie word for word.

Now, Dugu Junjie can be regarded as high-spirited, and he is the head of the space base jointly built by Dayang Group and ASEAN, and the Dawning space. As the bridgehead for the entire Tianyuan Star to enter space, the Dawning Base has a great influence on the current development of the entire space.

In other words, Dugu Junjie is now equivalent to the Governor of the Space Division!

Of course, it is impossible to completely have the final say. Dugu Junjie also has Shen Haiming under him, who is also directly responsible to Zhang Hao and the board of directors of Dayang Group, while the rest of the ASEAN countries also have their own representatives.

After Dugu Junjie received Zhang Hao's decision, he immediately gave Shen Haiming an order, and Shen Haiming gave an order to the Venus project team, and soon the news spread to Fang Hanle in Venus's outer space:

Dayang Group can rescue, and we will do our best to assist, but the rescue is not free, please confirm.

Five minutes later, the robot of the Ocean Group began to move, and according to the coordinates provided by Fang Hanle, it explored the wreckage site.

Just wait. It's not clear which robots will take how long to search for their targets, but it won't take days. With the cultivation of Shi Canghai and others, there is no problem at all in carrying it for ten days and half a month.

............

The Ocean Group is only simply concerned about things on Venus, and more energy, manpower, material and financial resources have been transferred to new projects: a series of space engineering construction.

The first project is the long-planned space cannon of the Ocean Group: the Super Rail Cannon.

Then there's the space factory, led by the Ocean Group and with the participation of all ASEAN parties, and of course, space mining. After several years of planning, related technologies, etc., finally matured.

And Zhang Hao, as well as Dugu Junjie, and even the entire ASEAN, are mainly focused on the space cannon. Of course, the space factory is important, but everyone knows the significance of the giant cannon. To fight the Red River civilization, you need powerful and unique space weapons.

Strong, needless to say, not strong enough to counter the threat of the Red River civilization.

And the characteristics are also very important. This involves the issue of the defense of weapons.

According to the materials translated by the Xuanhuang civilization, the main attack weapons in the space of the Xuanhuang civilization are energy cannons (related to aura and formations), laser cannons, particle cannons, and some 'super magic weapon' equipment, but these weapons may be powerful in attack, but they are also relatively easy to defend.

In the later period, the Xuanhuang civilization also seemed to have developed technologies such as electromagnetic cannons, but not much actual combat information was found. It can be assumed that this technology has not been developed.

As for the Ocean Group, it is the electromagnetic rail cannon that comes up.

Compared with those laser cannons, particle cannons, etc., rail guns have many disadvantages: bulky, long energy storage time, slow flight speed, high cost, need for special projectiles, and the system is susceptible to electromagnetic interference, maintenance troubles, etc.

But there is one characteristic that makes the rail gun stand out, that is: powerful to brutal destructive power! Powerful to resist, purely physical limit kinetic energy!

No matter what kind of defense, once you are hit by the rail cannon, you can only pray that your defense is strong enough. Because for the time being, there is no second way except to carry it hard.

Unlike lasers, particles, and the like, it's enough to get some kind of defensive coating.

Not long ago, the experimental model of the rail cannon tested by the Dayang Group on the ground was a great success, so the Dayang Group will now try to build a larger and more powerful starry sky cannon in space.

Even the drawings of the giant cannon have been circulating in a small area. In space, the relevant personnel in ASEAN can basically see the drawings.

For example, Liu Xinhai, the crown prince of the country of Qixia and Zhang Hao's eldest son, lay in front of the drawings at this time and watched quietly, and then listened attentively to the discussion next to him.

To build the Starry Sky Cannon, you need strong engineering construction capabilities. At present, only the first construction group of Dayang Group has the ability to build such projects.

The first construction group of the Dayang Group was formally established in the last five years, but its predecessor was Zhang Yueshan, the director of the Engineering and Construction Department of the Dayang Group, and Zhang Yueshan was responsible for the 'land bridge' that connected the West of the Fertile Continent and the Turbulent Continent at the beginning.

Later, Zhang Yueshan was responsible for the port construction, urban planning, transportation planning covering the entire Chentu Continent, and even the construction planning of the space center of the Dayang Group. Even the construction drawings of the Dawning space base have Zhang Yueshan's signature.

There are too many talents in Dayang Group, but they have rarely received attention from the outside world before, because everyone is more concerned about spiritual matters.

It was only recently that the rest of the parties finally noticed these talents. When the Xuanhuang Group was unable to build a space center and could only rent the space base of the Dayang Group, everyone finally woke up.

Now, the technical design and drawing of the rail cannon are completed by Ge Dong and relevant scientific researchers. However, the specific construction and construction need to be transferred to Zhang Yueshan and the First Construction Group.

With the help of Ge Dong and other scientific researchers, Zhang Yueshan led his technical team to discuss for half a month, and finally finalized the construction plan. At this time, the feasibility study drawings provided by Ge Dong and others have been changed beyond recognition.

The space environment is very different from the terrestrial environment, and gravity, magnetic fields, temperature, cooling means of equipment, power supply methods, construction equipment and technology, and environment all need to be carefully demonstrated.

Fortunately, the team of Dayang Group has rich technology, and half a month later, the railgun project at the level of the Star Giant Cannon finally began.

Thanks to the fact that the Aurora space base itself is a fully functional space factory, it is much easier to build the rail gun. However, even if it is much simpler, the construction of the starry sky cannon is still the most challenging super project at present.

The first is the core component of the rail gun: the guide rail.

The guide rail is also a bracket, which needs to be used as a gliding track for the rail gun on the one hand, and a support structure for the coil on the other hand;

The design length of the Star Cannon is 80 kilometers, and the design goal is to accelerate a special shell weighing 50 kilograms to a speed of 500 kilometers per second.

According to the arguments of the technical personnel and military personnel of the Dayang Group, only when this speed is reached can it be regarded as a starry sky weapon! Only at this speed can the enemy be unable to react.

In fact, the speed of 500 kilometers per second is still pitifully slow in the space environment. Thinking about the speed of light at 300,000 kilometers makes people feel a sense of powerlessness from the heart.

Half a month later, when the robot on Venus finally found Shi Canghai and the three of them, Zhang Hao had already arrived in space to personally observe the craziest engineering construction in the history of Dayang Group.

Standing in the void, surrounded by the Dawning space base, Zhang Hao saw the magnificent scene of the construction of the project.

The Aurora space base has reached the scale of 1,000 meters, with a central main height/thickness of 400 meters, and is a veritable space city. However, most of the city is made of steel shelves, and seventy percent of the area belongs to the factory area!

At this time, the factory area is building the core component of the rail gun: the electromagnetic guide rail.

In order to achieve the effect of magnetic levitation, the guide rail of the rail gun adopts a triangular structure, or a three-phase structure, which corresponds to the current main power generation technology and three-phase electric technology of Dayang Group, which can improve the capacity of the rail gun to the limit.

However, it is extremely technically difficult to do so. Compared to the double guide rail, the technical difficulty has increased by an order of magnitude.

But there are also more benefits. During the firing of the rail gun, the projectile is always suspended in the magnetic field without friction. The trajectory can even be slightly adjusted by a computer, as long as the magnetic field in one area is strengthened as it approaches the exit.

However, in order to produce such a near-perfect rail gun, it needs deep industrial technology to support it. At this time, in space, a feast of technology has begun.

The nano-tungsten steel powder sent from the ground is smelted in space, and the nano-cermet sintering technology developed by the Dayang Group is used to cast the guide rails little by little in the gravity-free environment of space.

The design length of the guide rail is 80 kilometers, there is no splicing, and it is a hollow structure - the solid structure is of course better, but the cost is too great.

I only saw that in space, the electromagnetic furnace driven by the nuclear power plant sintered tons and tons of nano-tungsten steel powder at high temperature and high pressure, and finally formed a singular material with both ceramic and metal color - nano-tungsten steel ceramics!

The metallic luster is cold, with the characteristic black-gray color of tungsten steel, while the color of the ceramic, similar to the luster of jade, is warm and translucent.

The super tube, with a diameter of up to 50 meters and a wall thickness of 30 centimeters, extends little by little in space, and is surrounded by laser measurement technology to ensure that the accuracy of the guide rail is controlled within 1mm. Because the magnetic levitation technology is used, the accuracy requirements of the guide rail can be slightly lower.

However, Zhang Hao soon found Zhang Yueshan, who was in charge of the construction of the project: the accuracy of 1mm may be enough, but we have to be strict with ourselves;

For every 1 filament, or 0.01 mm, the accuracy increases, the worker's salary increases by 1%;

When the accuracy exceeds 0.1 mm, for every 0.01 mm of accuracy improved, the salary will increase by 2%;

Above 0.2 mm, the salary increases by 3%, and so on. If the accuracy is greatly improved, the construction period can be extended;

Of course, if the accuracy is less than 1mm, the direct fine is 10%, less than 1.2mm, the fine is 50%, and if the accuracy is less than 1.3mm, the relevant responsible person will be replaced.

The stick and the carrot fell at the same time, and the enthusiasm of the staff was immediately mobilized.

The spacecraft shuttles between heaven and earth, transporting materials, the staff is busy and cautious, in the silent space, countless people are sweating, and from time to time, a laser brushes the surface of the guide rail, polishing the surface of the guide rail to almost absolute perfection.

There are even technicians who directly touch the cooled rails with their hands. The human hand is the most sophisticated machine in the world, and a trained person can feel the most subtle differences. Then, the skilled workers will use kraft paper and ultra-fine tungsten steel powder to polish the guide rails by hand little by little.

The production of guide rails is very slow, mainly because tungsten steel powder can not keep up, and the production process does not allow the slightest error. The current rail cannon carries the hope of the entire Tian Yuan Star.

However, when everyone was still looking at the crazy project of Dayang Group with shocking eyes, Zhang Hao's heart was twitching: overestimating the production capacity of Dayang Group.

At present, the new tungsten steel powder production line is still under construction, and it will take at least half a year to put into operation, and the current production line and production technology, the cost price of tungsten steel powder is still very high!

The cost of this nano-tungsten steel powder was once sold as a nano-level spiritual material, and the market price was calculated by grams, and the highest market value was as high as 10 spiritual yuan per gram - this is because of recent technological advances.

If Dayang Group uses it itself, of course, it does not need to be so high-purity, but the cost price is also about 10 yuan per gram. And if it is sent to space, the cost per gram is as high as 14 yuan. Counting the wages of the workers and various expenses, the actual cost of the rails of the Star Rail Gun is as high as 16 yuan per gram.

The rail cannon has a guide rail of 80 kilometers long, a diameter of 50 meters, and a wall thickness of 30 centimeters, and the inside of the guide rail is reinforced by raised fins. The design mass of one guide rail is 24 million tons!

According to the cost of 16 yuan per gram, this time the cost of the guide rail gun alone is as high as 100 billion yuan.

It can be imagined what kind of blood is in the heart of Boss Zhang Hao. Fortunately, new technologies are breaking through, and this time the construction of the starry sky cannon has also received a lot of support from all sides in ASEAN. Even the Xuanhuang Group and Hetu World have considerable support in order to obtain technology.

A super project, first of all, is also a super capital bonfire - a grand event to burn money.

This lasted for more than half a month, and Zhang Hao was also relieved when he saw that the project was progressing smoothly. In any case, technology is more important than wealth in the current environment.

No, Zhang Hao is still heartbroken, the person in charge of the Asgard Space Base, Ao Qiushuang from Guanghan Palace, came in and asked the Dawning Space Base for help again: The 10 people trapped on Venus are in urgent need of rescue. And now there is only the Ocean Group with rescue technology.

"Ten people, isn't it three?" Zhang Hao was dumbfounded, what were the other seven doing.
