Global Catastrophe: I Am Cultivating Immortals in the Refuge

　　 "Seven hundred point upgrade points, which is still a hundred points away from raising the level of the refuge. It seems that you can only upgrade the scientific research base."

　　 Chen Nuo sat on the sofa and pondered a little, and finally called up the system upgrade equipment panel and chose to upgrade the scientific research base.

　　 "Ding, you consume 400 points to upgrade and upgrade the scientific research base, and the area of ​​the scientific research base remains the same!"

　　 When the words of the system appeared, Chen Nuo had already taken the elevator to the third floor.

　　 "Scientific research, tune out all the things you can make at the moment." Chen Nuo directly ordered.

　　 In seven days, the second wave of disasters will come.

　　 Tens of thousands of underground core beasts will gush out of the pits created by planetary debris.

　　 By then, human beings will be reduced to food and lifesaving has become beyond the expectations of ordinary citizens.

　　 However, Chen Nuo knew that if he was hiding in the refuge, he could definitely survive the second wave of liquidation.

　　 But, it also means that he has no chance with a large number of upgrade points.

　　 Once he gives up these upgrade points, then his refuge can only stay at the current level.

　　 After all, as far as the current situation is concerned, the daily upgrade points are no longer enough to upgrade the refuge.

　　 So, he wants to make weapons!

　　 Make weapons that can kill the beasts at the core of the underground!

　　 thoughtfully, he looked at the various technological weapons and equipment projected on the center console.

　　……

　　 Gatlin: It takes five catties of iron, five catties of copper, and an energy spar to make!

　　 Grenade: It takes a pound of iron and a pound of copper to make!

　　Cannon: It takes fifty catties of iron, fifty catties of copper, and two energy spars to make!

　　Tank: One hundred catties of iron, one hundred catties of copper, and ten energy spars are needed to make!

　　 Cannon shells: It takes one catty of iron and ten catties of gunpowder to make!

　　 Tank shells: It takes five catties of iron, five catties of copper, and twenty catties of gunpowder to make!

　　……

　　 At this time, many powerful weapons have been added to the weapons that the research institute can make.

　　 lists such as: tank, cannon, Gatling.

　　These are powerful weapons against the beasts of the core underground!

　　 At least, the power of the tank is still very huge, as long as you don't encounter thick-skinned monsters, it should be easy to solve.

　　 It’s just that these things needed...

　　 Chen Nuo frowned, but made up his mind.

　　 Within seven days, a tank or cannon must be made.

　　 At least, then you can kill monsters to get upgrade points.

　　 While thinking like this, he also discovered the value of "energy spar".

　　 "System, I want to exchange 100 upgrade points for ten energy spars!" He immediately ordered.

　　 This is necessary, at least, if you are currently making a tank, the energy spar is necessary.

　　 "Ding, you spent 100 upgrade points to buy ten energy spars! They are now stored in the material warehouse of the scientific research base!"

　　 Hearing this, Chen Nuo nodded, and then continued to watch the technology that the scientific research base can currently produce.

　　 Among them, there are still some things that interest him.

　　 For example, one of them is called Mecha Armor. This is an armor similar to an armored warrior, but rather bulky, just like the first-generation Iron Man.

　　 It’s just that, although it’s cumbersome, it’s still necessary to wait until one’s own strength can fight without relying on any weapons.

　　 can make others not recognize him after all.

　　 Otherwise, if you are recognized, God knows what crazy behavior humans will do?

　　 So, this naturally made it into Chen Nuo's list of must-orders in the future.

　　 Secondly, there are other lethal weapons that also made Chen Nuo's eyes shine.

　　 And what excites Chen Nuo the most is because he discovered that after the scientific research base has been upgraded, the unmanned reconnaissance aircraft and unmanned fighter aircraft he previously purchased can be upgraded!

　　 Unmanned reconnaissance aircraft: Upgrade requires an energy spar. After the upgrade, the size of the unmanned reconnaissance aircraft is reduced by one-tenth, and the control system is upgraded to set route mode!

　　 Unmanned Fighter: The upgrade requires one catty of iron, 0.1 catty of pure gold, and an energy spar. After the upgrade, the launching mechanism is added, and the control mechanism is upgraded to automatic attack mode!

　　 Seeing this, Chen Nuo's pupils couldn't help but enlarge.

　　 "0.1 catty of pure gold..." However, while excited, he was silent a little bit.

　　 "How much gold does 0.1 catty of pure gold need to refine?" he asked.

　　 "One catty of gold can produce 0.1 catty of pure gold!" Chen Nuo nodded his head because of the scientific research answer.

　　 "How many materials are left in the material warehouse? List them for me." Chen Nuo ordered.

　　 As soon as the voice fell, the light curtain on the center console changed the picture.

　　 "A total of 5.5 catties of copper, 10.6 catties of iron, 2.6 catties of gold, and 1.38 catties of masonry!"

　　 At the same time, scientific research also responded.

　　 Chen Nuo nodded and started to ponder.

　　 "It seems that tomorrow I will be out of the door to get some resources." After pondering, he raised his head and said:

　　 "By the way, make me a desert eagle."

　　Because I have to go out, I have to have self-defense weapons, but the artillery pistol is obviously not the first choice.

　　 After all, after going out, he faced people, not monsters.

　　 As soon as the voice fell, the robotic arms in the scientific research base began to operate busy.

　　 "There are still two hundred upgrade points left, what are they used for?" Chen Nuo pondered as he walked to the first floor.

　　 However, after thinking about it, he decided to go to bed first and make plans tomorrow.

　　 At night, he slept peacefully.

　　 But the people outside did not have his mentality.

　　 And, UU reading www.uukanshu. com If the people outside knew that he had been so "easy" and "chill" these seven days, they were afraid they would be suicidal.

　　……

　　 At this time, it was located in an underground refuge in Huaxia Emperor City.

　　 This is the refuge of the government headquarters.

　　 Because the ground headquarters disappeared, they moved here.

　　 Together, naturally there are people from the space agency.

　　 After all, they must always pay attention to the planetary debris.

　　 At this time, when the vibration and roar disappeared, everyone was a little excited and puzzled.

　　 Until, the people from the space agency passed the news.

　　 Then, everyone was neatly relieved.

　　 "This sudden disaster finally disappeared!"

　　 "Fuck! It's liberated!"

　　 "The disaster... is over!"

　　 "We were rescued!"

　　 "God Sun Di! Drink all night tonight! I'm a treat!"

　　 The whole command post cheered.

　　Some people even burst into tears.

　　 There are also people who have lost their loved ones in the disaster, so they are silent in an extremely uncomfortable feeling.

　　 You know, for these seven days, everyone was in awe.

　　 Now, the feeling of relief in their hearts can even be imagined.

　　 But soon, everyone fell silent.

　　 They started to work.

　　 They want to re-access the entire Huaxia circuit, and then send the message to all places in Huaxia.

　　 Let everyone know that the disaster... is over!

　　 At the same time, they also began to quickly restore the entire Huaxia system that was paralyzed by the disaster.

　　 After all, the loss this time is extremely heavy!
