After stepping into the lunar base again, Zhao Yu breathed a sigh of relief. He always felt uneasy when staying on the spacecraft.
"Sir, welcome back!"
Uncle Da took the other nine androids and stood at the entrance of the base to greet them.
Zhao Yu smiled, chatted with a few people for a while, and then went straight to the base control room.
According to the list given by Uncle Da, consume all the more than 25,000 technology points in hand.
[Base: Level 1]
【Experience:/】
[Experience points are full, do you want to upgrade?]
"Yes!"
【Upgrade successful!】
[Base: Level 2]
【Experience:/】
[Note: A movable sub-base can be added to the current level]
The location of the sub-base was already planned, and Zhao Yu directly chose a mothership parked on the moon as the sub-base.
In this way, even if the lunar base is destroyed, there will still be a mothership that can continue the system technology.
After reaching the second level, all seven basic sciences that were originally stuck at 1.99 and could not be upgraded have become upgradeable.
Zhao Yu checked and found that the cost of upgrading the seven basic sciences had increased to 0.01 hundred science and technology points per upgrade.
If the 7 basic sciences are to be upgraded to 2.99, a total of 70,000 technology points are needed.
Correspondingly, the experience points required to upgrade from a level 2 base to a level 3 base have also increased, becoming 200,000.
Zhao Yu took a brief look and then opened the redemption list, wanting to see the technology points required for particle black holes, but after searching around, he didn't find any.
"It should be that the level of the seven basic sciences is too low..."
The upgrade of the base level to level 2 only means that he can redeem all technologies below 2.99 through technology points, but the prerequisites for each technology still exist.
Taking another look at the technology points on hand, there were only 300 points left. Zhao Yu thought for a moment and found the recently redeemed life science products.
After asking the system one by one, after deducting the upgrade costs of various types of research institutes, a total of about 15,000 technology points can be returned.
"Fifteen thousand technology points are enough for the time being..."
Zhao Yu left the control room and planned to discuss with Uncle Da how to upgrade next to maximize the benefits.
……
"The Pangu civilization has an orbital defense circle around Mars, all composed of base points equipped with laser systems..."
"Before we break this defensive circle, we cannot directly attack Blue Star..."
"Therefore, the early goal should be to break through this layer of defense..."
Near Pluto, on the Moro mothership, many captains held their own battle plans and started discussions with Moro.
"The laser defense system is one of the few methods that can withstand the attacks of a Level 2 civilization with the technological level of a Level 1 civilization..."
"The advantages are obvious. It reacts at the speed of light and cannot break through until the energy is exhausted..."
"The shortcomings are also obvious. As long as the energy of the base point is exhausted, the defense system will be destroyed..."
"A comprehensive attack is not advisable, it requires too much energy..."
"So, I suggest that before the fleet sets off, launch a large-scale attack on the Hellfire Point to consume the energy of all the base points in this area..."
On the three-dimensional star map, the Pluto point is to the left of the midline between Pluto and Blue Star. It will coincide with the midline in about 25 Earth days, which is the shortest distance for the Moro fleet to rush to the first line of defense.
"When our fleet arrives, the energy of the base point where the Hellfire Point is located will be almost exhausted. We can take this opportunity to defeat it in one fell swoop..."
"As long as this layer of defense is broken and a few shuttle ships are sent in, the war will be over!"
Moro held the simulator at the side and kept pressing the button. The results of each simulation were a complete victory. The biggest loss was only five shuttle ships.
"Okay, let's follow this tactic!"
Moro pushed away the simulator, stood up, and said energetically: "Seth, Milo has done a good job in detecting the enemy. I will serve as the commander and deputy commander of this vanguard army..."
"Lead the 2nd, 4th, 5th, 8th, 9th, and 10th fleets to fight at Hellfire Point..."
"In view of the long distance between the front line and the mother ship and the inconvenience of communication, you are granted the power to adapt to changes and decide on your own combat operations without notification..."
"The remaining 3rd, 6th, and 7th fleets, with full firepower, attack the Hellfire Point..."
"Industrial ships and resource ships go to Pluto to carry out logistics supply work..."
"Now, I announce that the operation to destroy civilization in the solar system has officially started!"
"Start the war!"
Following Moro's order, the entire fleet completely moved.
After being fully prepared, dozens of warships jumped out and flew towards the line of fire.
The remaining battle fleets dispersed, pointed out the muzzles of cannons of different calibers, aimed at the line of fire, and launched an attack.
……
"Sir, something big happened!"
At the lunar base, Zhao Yu had just completed the transaction with Yue'an City and recovered 15,000 technology points. He was about to go to the control room to redeem technology when he was stopped by Uncle Da.
"What's wrong?!"
"The Moro fleet launched an attack on us!"
"What?!"
Uncle Da appeared with a gravitational wave detector and said: "More than sixty Moro warships have left Pluto and are heading towards the first line of defense..."
"In addition, the dozens of warships left behind released a large number of attacks on our first line of defense..."
"They actually took action so quickly!!!"
The spacecraft on Jupiter was captured before, and the Moro fleet did not take action for many days in a row, which made Zhao Yu think that the other party might not take action in the short term.
Who knows, it didn't take long for the attack to come, and it would go all out as soon as it started.
"They did not directly attack the base point area where the Eighth Military Base is located, but attacked the defense line where the Fifth Military Base is located..."
"According to calculations, they want to consume the energy of the defense line where the fifth military base is located. When the more than 60 warships arrive, they will break through..."
The star map shows that when the enemy warships arrive 25 days later, the defense line where the fifth military base is located is exactly at the center line of Hellfire, which is the shortest distance.

"Can we defend against the first wave of attacks?"
"Yes, but judging from their appearance, the attack should not be interrupted within these 25 days..."
"It only takes 15 days for the energy replenishment speed of the fifth military base to be unable to keep up with the consumption speed..."
"At that time, the resident warships of the fifth military base must be used..."
"But the battleships we stayed there were designed in the early stages. Most of them are destroyers, battleships, etc. There are only a hundred frigates that can really withstand attacks..."
Zhao Yu quickly asked: "Is it too late to send the frigate from the base over now?"
"Within enough time, with full firepower, the frigates will be able to arrive at the front line in about four days..." Uncle Da nodded, but soon became worried: "The enemy still has sixty approaching warships that have not opened fire. Once
Upon arrival, if there is a sudden outbreak, our defense line will easily fall..."
"How many frigates are there in our base now?!"
"After the arrival of the Moro fleet, the base began to explode. In the early stage, various types of warships were produced in proportion. Later, after it was discovered that only frigates could effectively defend, they began to produce frigates alone..."
"The total number of existing frigates in the base is about 150,000..."
"Send everyone over to support the fifth military base. Be sure to hold the first line of defense!"
"Yes!"
After Uncle Da finished speaking, he added: "Sir, the first line of defense is far away from us. The round-trip communication time is close to 15 minutes. It is inconvenient to command. I suggest sending someone over to supervise the battle..."
"Who do you think is appropriate to send?"
"Li Zongheng, he has been the security director of the base for a long time and has rich experience. He should be qualified for the job..."
"Okay, then let Li Zongheng go and take charge of the fifth military base!"
Uncle Da then said: "Sir, some of the resources reserved by our base are not enough to make frigates. We need to obtain them from Blue Star..."
The moon base currently reserves more than 5 billion blue moon coins equivalent resources. If all of them are used to build destroyers, battleships, and transport ships, it will be no problem to build 500,000 ships.
However, some of the rare earths needed to build frigates can only be obtained from Blue Star, and the reserves of rare earths are about to be exhausted.
"Then mobilize resources from Blue Star. Don't worry about whether they will be discovered by the Blue Star people. Send all Xiaotian out to exploit resources with all their strength to ensure that the frigate production line cannot be stopped..."
"The longer we last in this battle, the greater our chance of turning defeat into victory..."
