As Mu Chen thought, the difficulty increased quickly.

That night, a group of bats the size of a basketball flew into the house in the darkness of the night, and their attack was very peculiar, that is, they squeaked around the house.

This time it was a sonic attack, and Liu Ruyan really didn't have the means to deal with it, so she had no choice but to block her ears, and then quietly took a bow and arrow to aim at the window.

It's not quite right to say that it is a window, because this is the attack port left by Mu Chen in advance, which is suitable for long-range weapons.

Hundreds of arrows are shot every day, and today's Liu Ruyan can easily aim without the need for precision.

"Squeak......

With a long sound, one bat fell to the ground, and the rest of the bats instantly scattered and flew towards the forest.

was shot two more by Liu Ruyan.

However, shortly after Liu Ruyan fell asleep, he was woken up by a bat again.

"I'm xxxx, you're xxx......" Liu Ruyan scolded the swear words that needed to be silenced for the first time, and then picked up the guy and went out to fight.

This night, Liu Ruyan did not rest well, although he did not go out with dark circles under his eyes, but his mental state was not good enough, and if he fought, it would inevitably be dangerous.

And monsters also appeared in the forest, and their size increased, Liu Ruyan took a look at it and began to slaughter.

However, she was measured and did not go deeper, and went back to catch up on sleep by noon, and began to upgrade the psionic shelter in the afternoon.

In order to get a good night's sleep, she also spent a lot of money, and most of the resources of more than a dozen backpacks were consumed.

Then the first-level psionic shelter was built, and Mu Chen was still restricted and could only make cyan grades.

But it doesn't matter, he has the power of the Ice Calamity, and at the beginning, the fourth and fifth levels could compete with the sixth level of strength, as long as the strength level was high enough, the level could not be limited.

With Mu Chen's understanding of psionic energy, even if there were many mistakes and omissions, there was no problem with low-level utilization.

So, from time to time, someone's exclamation sounded in the room: "Wow! This bed ...... Outrageous, automatically adjust the temperature? How, isn't this the function of the building after the second level? ”

"Shhh This pot can be cooked perfectly, and the food produced will randomly add an extra effect. ”

"Huh?! What's going on with this basement, how is it similar to a small square, and a piece of land?! ”

"Automated defense system? Delivers a beam strike every ten days, with an attack of 1000 for three seconds. ”

"Energy barrier, sound out?"

Liu Ruyan felt that she was not as shocked as she is today.

Forgive her for being a hillbilly, really, really outrageous.

Is this shelter really just a cyan grade?

Although the energy barrier consumes a blue spirit core every hour it is opened, although the beam strike takes ten days to recharge, although the farm in the basement needs to be replenished with various resources on a regular basis.

However, Liu Ruyan is sure that this is definitely not the ability that a cyan grade should have.

In addition, she was keenly aware of the characteristics of the building, sacrificing some functions and focusing on a few key abilities.

Psionic energy shelters all functions such as automatic ventilation, expelling toxic gases, cooling, and heating up, and now only the bed has this ability.

The intelligent control system can automatically plant, harvest, fertilize, cook and clean automatically, and also automatically make some props, and now all are castrated into an automatic defense system, just leaving the offensive and defensive parts.

This time, no matter how sluggish she was, she thought of a possibility: "Since last night, I have encountered bloodthirsty bats, and the monsters in the forest have been strengthened. ”

"This is obviously different from what the instructor said, and the shelter made today is in this situation, and my system is helping me!"

She was in an affirmative tone, not a question.

It was hot outside, and she lay down on the bed and began to think: "When I entered here, the props I made at the beginning were far beyond the standard. ”

"There were a few times when the props I made were just ordinary, and that was because I set my own conditions."

"So, the system has been helping me from the beginning."

"Why? Is the system self-aware, or is my system itself special? Or am I special? ”

Liu Ruyan was puzzled, but it did not prevent her from receiving the system's early warning, and at the same time, she also had to change her future survival strategy.

"Prepare today, try to go down the mine as early as possible, according to the rules, if I'm not at home, creatures other than the boss won't come to destroy."

When it comes to doing it, Liu Ruyan takes her backpack to cut down trees, she wants to make torches, she has never been to the core of the forest so far, and it is no surprise that the mine is over there.

Thanks to the power of psionic equipment, you only need to bring a few bags with you to go down to the mine, containing food and pickaxes, and when the food is almost finished, it is time to go home.

The reason why Liu Ruyan chose to go to the mine in summer is naturally because the surface is hot, and the underground is cool.

Her intentions were good, until the next day she found the cave from the dead trees in the center of the forest, and when she actually entered the mine, she felt like she was thinking too much.

Lots of big rats here!

This fierce woman who is not afraid of snakes and all kinds of fierce beasts is afraid of mice.

To be precise, it's not that I'm afraid, but that I feel disgusting.

Mu Chen noticed this, and rarely remembered that this was still a girl, according to her biological age, Liu Ruyan was only 16 years old.

I have to say that when the system has a benefit, let him experience the joy of cultivation, he decided to investigate for a while, hoping that this girl can change from "host" to other identities in his eyes.

Mu Chen has no requirements for the environment, and if he has requirements, he can also transform them himself, but the girl can't, in addition to rats in the mine, there are also bats, and the bats that fly in the night come from the mine.

The cave was dark, but it was daytime, and the bats were inactive and hung upside down from the roof of the cave.

However, there are only creatures at the entrance of the cave, and after going deeper, there is nothing else on the roof of the cave except for the occasional droplet of water, and gazing at the cloak perfectly solves the problem of water seepage, so you don't have to worry about getting your clothes wet.

About 200 meters forward, there were some forks in the cave, which became narrow, but there were also ores, which grew very perfunctory, that is, a stone protruding from the stone wall, and when knocked out, the iron ore would fall.

There are also occasional copper and gold mines.

The least is the black gold mine, which belongs to a special spiritual material, and Mu Chen is confident that he can use it to create a purple weapon, but he doesn't know whether the will of the level agrees or not.

Mu Chen thought about everything, and Liu Ruyan ......

Bang dang!

Bang dang!

She was digging hard, eating barbecue when she was hungry, drinking water when she was thirsty, digging a hole when she was tired, and then making a makeshift shelter with minimal materials.

There is a universal system, she doesn't suffer much, it is mining every day, after four days in a row, she can't stand it, but it's not enough, especially crystal mines.

This thing was only mined on the fourth day, and when she got it, she unlocked a new recipe.

Seeing the crystal mine, Liu Ruyan was 100% sure that there was something wrong with her system, it was too strong.

Because the instructor said that the crystal mine needs the multi-functional mining tools dropped after the death of the boss in the fall to be mined, and the level of other tools made is not enough.

But here, it's easy to dig up, and there's nothing that doesn't have enough grades.

Mu Chen was a little more surprised than Liu Ruyan, the crystal mine unlocked various defense tower recipes, as long as the materials were enough, it was completely possible to turn survival into a tower defense game, and the monsters hung up before they got close.

The ore can be refined, Mu Chen used a large amount of ore to get a new power of fate, he added the two parts he originally had, and there are currently four parts, the change is not visible, it should be that the accumulation is not enough.

And after entering the new world, the power of fate has never been consumed, which means stability, but it is not a good thing, at least Mu Chen can't get new information.

It was now the 43rd day of entering the New World, and through Liu Ruyan, the host, Mu Chen had collected a lot of information.

First of all, the host is happy in the new world, but it is also nostalgic for the past, so Mu Chen captures the heart.

I know that many years ago, a place called the earth, suddenly all fantasies became real, and various civilizations were almost wiped out, but fortunately, the level of technology was enough, and I barely survived.

Later, some humans entered the fantasy world, and they gained power, and they invariably protected the remaining ordinary people.

Finally, there is the arrival of "mortal dust".

Mortal dust is the new world.

To enter it, you must first have a system, whether it is complete or incomplete, in short, with the system, you can be transported to the trial level, a total of three levels.

The first level is solo survival, and after passing it, you can open the profession.

The second level is multiplayer survival, allowing you to defend against foreign enemies together, and open the full attribute after passing.

The third level is a challenge, and you can enter the real mortal dust by passing it, which is a big world that integrates technology, spiritual energy and other systems.

You can adventure, treasure hunting, study, research, and in short, you can find everything inside.

And the power system of each person determines how far the future can go.

Mu Chen wanted to know how humans cultivated the system, but this was not something that Liu Ruyan could know.

After knowing that the second level was multi-person cooperation and that he would enter the mortal world in the future, Mu Chen remembered when he was still in the Star Sea World.

The snake man and the old man have both said that they may be allies in the future, and it seems that this is where they should be shipped.

But Mu Chen was really puzzled as to why the old man knew so much, while Mu Chen himself knew very little information.

At the end of the countdown, Mu Chen also devoured a large number of worlds, and he had studied it repeatedly recently, and there was no relevant content at all, but those plot pages, Mu Chen had collected a lot.

At present, the plot page cannot be obtained to the outside world, and Mu Chen cannot observe it.

In the entire sea of stars, Mu Chen felt that the plot page was the most special, the entire sea of stars had disappeared, only a few systems were still there, and other things were stored in the form of spiritual machines, and Mu Chen himself was a ball of spiritual machines.

However, the plot page is still a plot page inside the ice crystals.

In other words, they are of a very high level and should be Mu Chen's backup choice.

Now, Mu Chen hopes that Liu Ruyan will be more powerful, and bring more power of fate.

To this end, he is willing to create a suitable tool for the host.

For example, this time, the pickaxe is all to speed up the collection, but it is still an ordinary psionic pickaxe, and now there are other iron ores, which can be exchanged for more efficient.

It's just that this girl is too frugal, and sometimes thrift is not a virtue.

Suddenly, Mu Chen's inspiration flashed, and he seemed to have a new idea!
