"Commander, the tech points are already needed to level up, do you want to upgrade?" The adjutant's hologram appeared in front of Lin Chen and asked. She always does this when no one is around, and Lin Chen doesn't say anything, because there is always a sense of déjà vu of a sci-fi blockbuster.

"Level up!" Lin Chen is looking forward to what new technologies will be unlocked after the system upgrade.

"Ding, consume 100 technology points, the "Armada System" has been upgraded to level 3, and the next level is required: 200 technology points."

"Ding, congratulations on completing the main quest, whether you have started to strengthen your body." The voice of the system sounded in his mind, and Lin Chen was overjoyed in his heart, he had waited too long for this moment.

"Start strengthening!"

As the voice fell, Lin Chen felt as if a liquid was pouring down from his head, contrary to the first time, this reinforcement gave him a feeling of coldness, he couldn't help but shiver when he was frozen, his teeth kept colliding, and the extreme cold made him very uncomfortable.

He really wanted to pass out at this time, but his consciousness was extremely awake at this moment, and as time passed, his brain became more and more awake, and the fatigue that had made him a little groggy was also swept away, and he was indeed extremely happy after the pain.

This is the more powerful power he is after.

However, the imaginary muscles swelled, and the dirt that was discharged still did not appear, and it felt like nothing had changed, as if it had not been strengthened.

"Xiaoya, you can explain to me, didn't you say last time that there will be changes after you are promoted to the F rank? What's going on here? Lin Chen can clearly feel that there is only one muscle in his abdomen, he has read a lot of novels, which one of the protagonists strengthens the muscles that are not toned, and makes the girl blush and shy, how did he get to himself This is a sick look?

"Do you really want to say it?" Xiao Ya's tone was a little hesitant.

"Say!"

"You're not going to be angry, are you?" Xiao Ya still asked cautiously.

"Say, I'm not going to be angry!" Lin Chen was already impatient, when did this elf grind like Meng Shuhua

"Oh well! I'll tell you. In fact, the enhancement of the system is different from the kind of enhancement you think, the enhancement that the host thinks belongs to genetic evolution, and the genes that are close to perfection will allow humans to have great strength, but this method has a limit, the genes of the earthlings are not perfect, and the combat effectiveness of the perfect gene warriors cannot even reach the F level, and there are two ways to continue to improve the strength at this time. First, the replacement of the body, which is a simple and crude way, but it is very risky. The second is to inject nano cells, and replace the cells with nano cells one by one without affecting the body's functions, so as to achieve the effect of strengthening. Xiaoya explained.

"So you mean that my body is already full of what you said?" The shock in Lin Chen's heart didn't even know how big it was, he didn't dare to think about replacing cells, so his cells were replaced, what was he now? He asked tremblingly, "I...... Can it still be considered human? ”

"Of course it's human, you can rest assured that nanocells will not affect your life, and instruments on earth can't even detect the existence of nanocells." Xiao Ya tried her best to explain to Lin Chen, after all, if one was not good, Lin Chen would give up accepting the reinforcement. Finally, he added: "Even if you want to do something shameful, it won't have any effect, you will have what you should have." ”

Hearing Xiao Ya say this, Lin Chen's mood was much better, yes, even if his body changed? Since the technology on the earth can't discover the existence of nanocells, then just live a normal life, why do you want so much?

Lin Chen couldn't help but want to slap himself, being smart was mistaken by being smart!

"Ding, there is a new scientific research project, please check it out for yourself."

"Ding, there is a new task, please open it and view it by yourself."

The voice of the system kept coming from his head, making Lin Chen overjoyed.

"Open the R&D center."

"Yes, a lot of technology has been unlocked, so the strength will be greatly increased." Lin Chen nodded, quite satisfied.

"Commander." The adjutant's voice came suddenly.

"What's the matter?"

"As planned, the reconnaissance ship sent by the US imperialists has been surrounding the open and has not entered for a long time, and the ore under the sea has basically been collected." The adjutant said.

"Haha, that's good." Lin Chen couldn't help but smile, the last time he sank the ore ship and put the two people back, it was actually for a purpose, not only Lin Chen was playful, but the most important thing was to deal with the next reconnaissance, the two people who escaped after this life and death crisis will definitely have a fear of the fleet, and they will describe the fleet as very powerful, the mining company will definitely have scruples, dare not go deep, and apply to the US imperialist for fleet protection, which has bought Lin Chen a lot of time to collect ore, otherwise the ore ship will sink, the other party will definitely investigate, as long as it is in this sea area, You will find these submarines, and it will be very troublesome to continue collecting them.

"Any other good news?"

"Not for now, but there's bad news." The adjutant said.

"What's the bad news?" Lin Chen frowned slightly, looked at the adjutant and asked.

"Because of the ore ship incident, the number of energy refining plants is increasing, although they are all built in sparsely populated places, but after a long time, they are easy to find." The adjutant said.

After listening to the adjutant's answer, Lin Chen was silent for a while, this matter is very important and must not be taken lightly.

"What about the polar regions? Can it be built? Lin Chen pointed to the two ends of the map, which were the South Pole and the North Pole. These places are rarely visited and much safer than the high seas.

"Yes, and according to the system analysis, the amount of mineral deposits in the polar regions is very significant and can be used for collection operations." The adjutant replied. Then he added: "I think building a base in the Antarctic would be more secluded than the Arctic." ”

"Since you've said so, let's choose Antarctica, where the temperature won't affect our fleet, right?" Lin Chen asked, he was worried that the low temperature would make it difficult for the fleet to move an inch.

"Don't worry, it's not enough to stop the fleet." The adjutant's answer was full of confidence.
