The lowest price of the system is 5,000 units of crystal refining once, and almost all sellers are listed at this price, and the sales information is as high as tens of billions.

"Buy two R&D opportunities!" Qin Xuan decisively ordered!

Blue Fox: Friendly reminder, there may be mistakes in the master's current operation, and we only need to specialize in one technology, and we don't need to be proficient in everything!

Blue Fox: The saved money can be used to buy energy, or to buy equipment, and the effect is the greatest!

Qin Xuan said with a faint smile: "Just keep buying, this is a super scientific research and exploration base, not Qin Fang's war fortress!"

Blue Fox: Purchased two R&D opportunities at the lowest price, consuming 5,000 units of crystal refining!

"Dutu, toot!" Qin Xuan had just made a successful purchase here, and a large wave of news came one after another.

Qin Fang's message came from the chat bar: "Brother Qin Xuan, you are crazy, how can you find someone else to buy the R&D opportunity, you should buy it from me, I still have 19 idle opportunities, I can sell them all to you!"

Qin Xuan just responded by giving her a smiley face, and he didn't know what to say.

Qin Fang's super technology was just the development of a super weapon system, and nothing else was studied.

She is now level 200, and she only has one super technology, and the remaining 19 research opportunities are all useless.

After perfunctory Qin Fang, Qin Xuan directly clicked on the research and development options, and developed the other two super technologies!

Blue Fox: The super technology has been developed, and the interface has been automatically closed!

Blue Fox: Here's a quasi-super tech!

This time, the options have been changed from three to six.

They are: Composite Memory Armor technology, which has excellent defense performance, can automatically repair damaged parts, and greatly improves the endurance of mechanical warriors!

"R&D!"

Blue Fox: Consume 1,000 units of crystal refining to successfully develop composite memory armor technology!

The Blue Flame Jet Engine, when assembled, can make all our combat units have the ability to fly at high speeds, and the maneuverability is greatly enhanced!

"R&D!"

Blue Fox: Consume 1,000 units of crystal refining to successfully develop the Blue Flame Jet Engine!

Doomsday War Song Score, which can be released in the state of war, increases the robot's attack power by 30%, attack frequency by 20%, and lasts for 24 hours!

"R&D!"

Blue Fox: Consume 1,000 units of crystal refining to successfully develop the Doomsday Battle Song score!

The field medical cabin technology can activate the robot's medical care program after wearing, and the robot can automatically implement battlefield rescue services, greatly improving our army's continuous combat capability!

"R&D!"

Blue Fox: Consume 1,000 units of crystal refining to successfully develop the field medical pod technology!

Grim Reaper's Roar Group Battle Stunt, Group Attack Skill, can stack mechanical attacks in an orderly manner, single damage explosion, and a steady stream of group attack damage!

Note: Unleashing this skill consumes a lot of energy, so choose carefully!

"R&D!"

Blue Fox: Are you sure you want to develop this?

Qin Xuan nodded in response: "Of course, research and development immediately!"

Blue Fox: Consume 2000 units of crystal refining, and the Grim Reaper's Roar skill has been successfully developed!

The mobile charging reactor can provide automatic charging services for robots within 3000 meters, and it is a must-have artifact for skill units!

"R&D!"

Blue Fox: Consume 2000 units of crystal refining to successfully develop a mobile charged reactor!

In addition to these super technologies, there are also a large number of advanced technologies, ordinary technologies, within the Tech Sphere.

However, at this time, Qin Xuan's money had already been spent, and he couldn't toss it if he wanted to.

After the money was spent, Qin Xuan withdrew from the R&D interface.

During this period of time, there were as many as 4,500 pieces of information about Qin Fang and their family.

Qin Fang: Uncle Qin Xuan, are you crazy, I can provide you with a mature R&D routine, you can develop my sister according to my template, I guarantee that she will be able to have half of my combat power in the future, although she has already embarked on the wrong path!

Qin Hu: Brother, you don't understand our mechanical clan at all, we are very grateful to you for spending all your money on the blue fox, but this is too wasteful!

Moran: I think the future of the Blue Fox is dark!

Qin Xuan also responded with a message: My science and technology ball is a scientific research base type, and I myself am also very passionate about science, of course I have to be fresh!

Qin Fang: Do you know that if you do this, it will seriously affect the combat efficiency of robots!

"My tech ball makes a level 200 robot, and it only costs 0.01 units to refine crystals!"

"Your technology ball, now to create a level 12 robot, it will cost 0.5 units of crystal refining!"

Qin Fang: Oh my God, one of your robots costs 50 times as much as mine, but I only need one robot to be able to defeat all your robots, and even directly urge your technology ball matrix!

"My energy efficiency is 1,578 times higher than yours, you know ......"

Qin Xuan gave the high-end technology of the science ball in the face, and the robot that the technology ball factory came with an energy shield, a first aid kit, a laser weapon, and skills, all of which required a lot of energy to produce.

Naturally, the cost of production is high, and Qin Fang thinks that it is too cost-effective.

Qin Xuan smiled faintly and said, "I'm a scientific research base, you can't always talk about war!"

Qin Fang: The direction of scientific and technological development of the mechanical clan is to improve combat effectiveness, do you understand?

Qin Hu: Okay Fangfang, you are now 200 years old, you have to compare with other people's level 12 science and technology balls, this is inaccurate, let my brother develop freely!

After the team chatted and suppressed Qin Fang's sentence, Qin Hu also sent a private message to Qin Xuan!

"Fangfang's IQ level has just begun to evolve, don't mind, brother!"

Qin Xuan immediately sent Qin Hu an expression of "angry praise".

It is said that Qin Fang thinks that Qin Xuan has "played the blue fox into a waste", and Qin Xuan also thinks that Qin Fang is a "big waste".

At level 199, you can't beat the mother queen of level 195, can this be considered strong?

After spending all the refining crystals and finishing the advanced scientific research of the science and technology ball, Qin Xuan breathed a long sigh of relief, and planned to return to find Sai Xishi to have a good "fun".

But at this time, he saw Sai Xi Shi walking out of the hall of the City Lord's Mansion with a sad face.

"Husband, you're back, I have a few bad news to tell you!"

"What's the bad news?" Qin Xuan asked curiously, "Maybe I can help you turn the bad news into good news!"

Sai Xi Shi glanced at Qin Xuan, and said in a coquettish voice: "I just sent back the news that our fish-man material procurement team was intercepted and killed by the elephant trunk man!"

"What?" Qin Xuan suddenly frowned, "Are those elephant trunk people crazy, let's go buy their ore, don't we give them mountains?"

"Those guys have taken a fancy to our storage ring, and the combat effectiveness of the fish-man warriors is too weak, so they naturally become fat sheep in their eyes!"
