Zhao Yu stood at the observation point of the base, picked up a telescope through the glass and looked into space.
In the lens, four spacecraft are arranged in a square formation, heading towards the orbit of the moon.
"Finally here..."
Zhao Yu thought that he would get the technology points after the deal was negotiated. Who knows, he waited and waited but didn't get it. Only then did he understand that the deal would not be completed until the other party's resources arrived.
For him, the original intention of trading watches is to obtain the technology points returned by the title of 'Mysterious Merchant', which is a one-time thing.
Trading watches with the Earth is just a one-time transaction, but if you invest in building a factory on the Earth, you will continue to receive resources.
Under Zhao Yu's gaze, the four cargo-carrying spacecraft slowly landed on the lunar surface, landing exactly where White Rabbit 9 left.
That was the transaction place agreed upon by both parties. A large number of Xiaotians were already on standby. The moment the spacecraft landed, the shield was turned on.
……
United Earth Defense Agency.
For the first time making a deal with aliens, all the staff of the newly established Defense Agency were on standby, keeping an eye on the situation of the four spacecraft.
On the spacecraft, there are not only the resources required for this transaction, but also various detection equipment.
Regarding Xiaotian's jammer, various countries have already recruited experts and held numerous meetings.
Many conjectures and methods have been put forward, and this time it can be used as a test.
Looking at the various measures they proposed, can you bypass the jammer and continue working?!
"All data are good, the spacecraft is landing..."
"Successful landing, all detectors turned on!"
"Opening completed..."
"The next step is to see if it can work!"
Not far in front of Colonel Chu, there was a row of sixteen screens, connected to four equipment on the spacecraft, ready to use various methods to try to bypass the jammer.
Wow!
As soon as he finished speaking, the sixteen devices in front of him went dark in an instant.
"It's all dark?!"
Colonel Chu frowned. Judging from this, these sixteen tests all failed.
Alien shielding technology is more powerful than they imagined and requires more in-depth research.
It was not only him who was frustrated, but also the experts and scholars who established these experimental methods. They were all very sad.
"Is it possible that the equipment is malfunctioning?!"
"Impossible, stop thinking about it. This is the trading point with aliens on the moon. Apart from the shield, there is no other possibility..."
One minute later, the sixteen screens returned to normal.
In the spaceship, all resources disappeared, replaced by 10,000 watches placed in four spacecrafts.
"Everything is gone, only the watch is left..."
"The transaction is completed, let's control the spacecraft and return..."
On the moon, after Xiaotian moved the resources away, Zhao Yu received technology points rewarded by the system.
Including the remaining unused ones in the past few days, Zhao Yu now has a total of 1,150 technology points.
"We can build a spaceship!"
Zhao Yu got the technology points and went straight to the control room, intending to build the dual-core power system spaceship worth 500 technology points.
After finding the nuclear-powered and magnetic dual-core spacecraft, Zhao Yu clicked on the exchange, but unexpectedly he got a prompt.
[This exchange requires first redeeming a ‘dish-shaped spaceship’ and a ‘U-shaped nuclear-powered spaceship’.]
"There are preconditions, and sure enough..."
Zhao Yu has encountered redemption items that require prerequisites before, which is not surprising.
He currently has 1150 technology points, the saucer-shaped spaceship is worth 400 technology points, and the U-shaped nuclear-powered spaceship is worth 450 technology points.
With the money on hand, he could buy it all, but he wanted to spend 500 technology points first to exchange for the gravitational lens.
Gravitational lensing is the upper limit of detection methods that can be redeemed by a level 1 base. It can detect everything through gravitational waves. Whether it is a natural celestial body or an artificial celestial body, as long as it has mass, it can be discovered by the gravitational lens.
After thinking about it, Zhao Yu pulled up the list of gravitational lenses and clicked on redeem.
[The gravitational lens was successfully purchased and consumed 450 technology points.]
Zhao Yu picked a place, set up the production line, and then turned to look at the spacecraft.
With 700 technology points remaining, only one of the two spaceships can be produced.
Zhao Yu thought for a while, copied the detailed data of the two spacecrafts, left the control room, and found the housekeeper.
"If it only moves between the earth and the moon, the saucer-shaped spacecraft will be faster..."
"If you want to install additional weapons, the U-shaped spacecraft can install more without damaging the power system..."
Zhao Yu was startled for a moment and said: "Will adding weapons to the saucer-shaped spacecraft affect its speed?!"
"Yes, the volume of the saucer-shaped spacecraft is much smaller than that of the U-shaped spacecraft. In order to increase the magnetic power, the entire spacecraft frame uses a special structure. Adding weapons will inevitably destroy this structure and eventually lead to a decrease in speed..."
"The U-shaped spacecraft is powered by a nuclear fusion reactor. Although the power system alone occupies one-third of the spacecraft, the remaining two-thirds can be arbitrarily equipped with weapons without affecting the power...
”
"What about the speed?"
"The maximum speed of the saucer-shaped spacecraft inside the planet is Mach 100, and it decays after leaving the planet. The fastest round trip between the earth and the moon only takes 4 and a half hours..."
"The U-shaped spacecraft has two power modes. The speed of conventional nuclear power in the universe is about Mach 50. Inside the planet, affected by air friction, there will be a slight decrease..."
"In addition to conventional power, the U-shaped spacecraft is also equipped with a nuclear pulse propulsion method, which can provide an extreme flight of 200 times the speed of sound for no more than 10 minutes at a time..."
"What will happen if it exceeds 10 seconds?" Zhao Yu asked curiously.
"It's going to explode!"
The advantages and disadvantages of the two spaceships were explained, and Zhao Yu began to consider them.
His current purpose in building a spaceship is to build a factory on Earth and take a sneak peek around the Earth.
From this point of view, it is obvious that a saucer-shaped spacecraft is more suitable. It uses magnetic power and is noiseless whether it is starting or flying.
Looking back at the U-shaped spaceship, it is obviously more suitable to modify it into a battleship equipped with weapons systems.
"Then this saucer-shaped spacecraft has no way to install weapons?"
"Yes!"
"You can build a sonic weapon production line and assemble it on a saucer-shaped spacecraft..."
"How powerful is it?!"
"The force caused to the building is very small, almost non-existent. At most, it will shatter the glass..."
"But it is fatal to living things. The specific data will not be known until it is built and tested..."
After chatting with the housekeeper for a while, Zhao Yu gradually came up with an idea.
As long as there is no problem with safety, first build a production line for the saucer-shaped spacecraft, and then install a sonic weapon system on the spacecraft.
As for the U-shaped nuclear-powered spaceship, wait for another ten days to save up the technology points and then get it.
Redemption completed.
After deducting 400 technology points to exchange for the saucer-shaped spaceship production line, another 50 technology points were deducted to build the sonic system.
In the end, Zhao Yu has 200 technology points left. According to the growth rate of 24 technology points per day, in another 10 days and 10 hours, it will be enough to exchange for the production line of the U-shaped nuclear-powered spaceship.
"Sir, Xiaotian has successfully received resources from the earth. Do you want to build them all into star destroyer cannons?!"
