"By the way, sir, there is another very important thing. When we made this spaceship, the material we used was only a common alloy among the class IV metals. If you have further requirements for the safety of the spaceship, I suggest you replace the material."

"Oh?" Fang jueyu forgot one thing. The spacecraft should not only be fast, but also its safety must be guaranteed. Naturally, the selection of materials is also very important.

"Host, this is much more important than a weapon," Xiaoyi also warned. "You know, if the spacecraft is strong enough, under the strong kinetic energy, it itself can become an invincible weapon. Whether it is a meteorite, a planet or a warship, it will be undamaged if it is directly hit head-on!"

"It makes sense. If the spaceship is strong enough, it will save money for weapons!"

"What is the strongest material you can use here?" Fang jueyu asked.

"It's kamner tungsten, sir," replied effara. "The metal we used was brent."

Host, this is kamna tungsten gold. It is one of the strongest metals in class IV metals. It can resist the temperature of supernova explosion. Even those who surpass it need to attack it with all their strength for several times to destroy it. It is at least 20 times stronger than this Bulun alloy. "

"Then use this one!" Fang jueyu said without even thinking about it.

"Yes, sir. What metal do you want to use as the mixed material with kamner tungsten?"

"No, just use a single kamna tungsten gold!"

"Ah?" Alfa was stunned.

"What's the matter? Is there a problem?" Fang jueyu asked.

Alfa didn't know how to explain to Fang jueyu for a while. As one of the most solid four grade metals, the price of Kamla tungsten gold is unimaginable. This metal is sold in units of ram, which is converted into the unit of the earth. 1 ram is equivalent to about 1.27 grams.

In general, even if some guests want to use this kamna tungsten gold, it is also made into an alloy with other metals. Generally, it is very luxurious to add 1%. Most people mix three or more kinds of alloys, which can not only ensure the strength, but also not so expensive.

Because kamna tungsten gold is a very special metal, it has the maximum strength and hardness only at 100% purity. Therefore, if the spacecraft is completely made of this material, even if the spacecraft rushes up against the exploding star, it will be undamaged.

However, this is not a model or a car. This is a spaceship. According to the density of kamna tungsten, if this silver wing demon uses 100% kamna tungsten, the required materials will be at least 20000 tons!

The strength and rarity of kamna metal naturally determine its extraordinary price. The price of kamna tungsten gold per ram has reached 200000 cosmic dollars. According to the minimum consumption of 20000 tons, this cost exceeds 2000 trillion cosmic dollars, but it is more than ten times higher than the price of spacecraft!

"Do you need to think again, sir?" With this series of figures, Alfa also made some amazing comments at a time. Ordinary material upgrades, up to 20 trillion ~ 30 trillion cosmic coins, are enough. 200 trillion can almost reach the top configuration of this silver wing demon.

But I'm afraid the person who plays like this is the first one in the world. The whole spacecraft is made of kamna tungsten gold. The spacecraft itself can almost be equivalent to an exquisite handicraft.

"Don't think about it, just follow what I said!"

"But Sir, the process of kamna tungsten gold is more complex, and because it is also a relatively rare metal, we can't take out so much inventory of 20000 tons of kamna tungsten gold for the time being. We may need to negotiate with our partners. I'm afraid you can't pick up the goods directly today."

"How long do you need?" Fang jueyu asked. Naturally, he didn't intend to drive the spacecraft away today.

There are two and a half years before the wormhole appears, and one year and five months before the cosmic slave Expo. If you can get the spacecraft within a year, there will be no problem.

"Sir, because it is customized, it will take about 0.8 cosmic years for our factory to reassemble and design."

"That's about eight months," Fang jueyu immediately converted, and there was no time.

"OK, let's arrange according to the configuration we just said. I'll pick up the goods in a cosmic year."

"Yes, sir. Please tell me your address and contact information. Then we can arrange delivery for you immediately."

"Oh, no need for this. I'm connected to your internal network through the space-time store. I'll deliver it through the space-time store at that time!"

"Space time store!" Alfa's eyes widened. Unexpectedly, this person was connected through the space-time store. She thought it was connected to the company's internal network through the space network. If this person can afford the space-time store, it doesn't seem so difficult to spend so much money to customize a spaceship.

"Sir, according to the regulations, if it is a customized spacecraft, you need to pay a 20% deposit first," Alfa said awkwardly. "But we don't have the materials you need, so you also need to bear the deposit required for the cost of that material, so you need to pay a deposit of 433 trillion cosmic dollars first. Look at this..."

"OK, I don't have the habit of paying the deposit. Just pay it all at once!" Fang jueyu took out the transparent card. "Can the card of cosmic bank be used directly here?"

"Don't worry, sir. Our virtual world is very well built. You just need to tell me your bank account. We can directly verify our identity here." Said alfa.

For ordinary people, their bank accounts are based on Star regions or star regions. There are still many inconveniences in consumption. Only the account of cosmic bank can be consumed in all cosmic civilizations.

However, the threshold of cosmic bank is also very high. Generally, assets are not qualified to open an account in cosmic bank. If you want to have a lowest level one-star account in cosmic bank, the required assets must exceed 10 trillion cosmic coins. Not everyone has such a huge deposit.

But alfa has also received many rich people and seen the savings card of cosmic bank, but this transparent card is the first time.

Without hesitation, she immediately took the identity checker, 2000 trillion cosmic coins, a one-time payment, which was a huge list. She made a lot of money just from the Commission.

Fang jueyu told Alfa his account number, and then a ray of light scanned Fang jueyu's personal information from that instrument.

"The appearance is consistent, the gene sequence is consistent, the personal account information is consistent, and the identity is confirmed. Mr. Fang jueyu, the owner of the nine level account of cosmic bank."

"Level 9 account!" The instrument in Alfa's hand almost fell off. She couldn't imagine that Fang jueyu had a level 9 account in the cosmic bank! Even the largest shareholder of their aribald company has only seven level accounts.

No wonder this big guy blinked and bought a spaceship with a price of more than 2000 trillion yuan. This money is not even a fart in people's eyes!

Soon, this sum of money was transferred to the account of aribird company, which once again confirmed Fang jueyu's identity. This account is really true and valid.

Looking at Fang jueyu's face, Alfa's heart was suddenly ready to move.
