Could it be that the big iron wall in front of him is exactly what the system stated in the tenth mission?

But although he discovered this metal wall, he still hadn't discovered his real secret.

As for what's inside the iron wall, I still don't know at all.

Does this count as completing the task?

Or is it that the system's mission is to let itself just find this one wall?

All of a sudden, Lin Yi's heart began to revolve, and many thoughts popped up at the first time, which made him puzzled.

He never imagined that the tenth system task would be completed in such a confused way.

Although it was said that I came here this time to complete this task, I never thought it would be so simple.

After all, in his impression, this system task is much more difficult each time than the previous one.

That is to say, the difficulty is gradually accumulated.

Because of this, this tenth system task is also the last system task required for the upgrade, which is definitely not an easy task for Lin Yi to think about.

It is precisely because of this that he has made plans to fight for a long time.

It is no exaggeration to say that Lin Yi has already planned to stay here for another month.

It's just that surprises often come so quickly.

Or, the old saying since ancient times, inadvertently inserted willows and willows.

Who would have thought that the secret of the moon in the tenth system mission was actually digging so many hundred meters into the ground?

Of course, if you think about it from another angle, then Lin Yi feels that this task is not easy.

After all, if a normal person's thinking is, wouldn't he think about digging through the moon?

I don't even think about drilling holes in the moon for no reason.

It is like the base that I built before. Although the foundation is very deep, it has only reached more than 200 meters, and it has stopped.

In such a deep situation, no abnormality was found, and according to normal people's thinking, they would not continue to dig.

And this time, I don't know what Lin Yi thought, but he started digging under the crater, which made him discover the secret at the first time.

Otherwise, digging 400 meters down the ground for no reason, I am afraid this is definitely not something Lin Yi can do in a short time.

After all, digging such a deep hole is of no value to Lin Yi.

Of course, it's all due to coincidence or luck. All in all, Lin Yi's tenth system mission has been completed.

This also gave him a long sigh of relief, and at the same time, he quickly recalled the words that the system just said in his mind.

The system is asking itself whether to turn on the upgrade and whether to upgrade the system to the third level.

For the current Lin Yi, this question can be answered with just thinking about it.

Just kidding, for more than a year, I have been racking my brains and trying my best to complete these ten tasks.

Now that the tasks have been completed, can it be said that he will leave the system unupgraded for no reason?

So why did you do this before?

Did you eat enough to support yourself, or did you lack a string in your mind?

Because of this, Lin Yi immediately gave the system an answer:

"Upgrade! Upgrade now!"

And after getting this answer from Lin Yi, the system also sounded a prompt sound in his mind for the first time.

[Master selection detected, system upgrade starts now.

The system upgrade is in progress, please do not interrupt the system during the upgrade, do not talk to the system!

The system is shutting down, please wait. . .

The system shutdown has been completed, and the unlock upgrade is in progress. . .

The new plane system module of the system is being loaded, and the loading of the new system module has been completed. . .

Ding, the system upgrade is complete.

Accompanied by this series of beeps, Lin Yi's heart couldn't help beating violently.

Just kidding, it would be a lie to say that you are not nervous. Who knows what changes will occur after this system is upgraded? Who knows if it will cancel the ability that he originally had before?

Of course, Lin Yi was vaguely certain of this in his heart. After all, the system upgrade will only get better and better, and it is impossible to regress.

That is to say, when the system upgrade is completed, there is a high probability that its ability to decompose and rebuild will not be canceled.

But at the same time, Lin Yi still has a concern, that is, if the system is really upgraded to the third level, because the system upgrade ability becomes stronger, the previous ability of decomposition and reconstruction will be judged as some incompetent ability. So delete it, then you will have no place to cry.

Another point is that although this system has been with him for a long time, to be honest, Lin Yi has not figured out what the principle of this thing is~www.mtlnovel.com~What is going on? .

It is precisely because of this that he really cannot be sure whether the upgrade this time is a blessing or a curse.

When he shouted for the upgrade, he actually had some regrets in his heart.

If it is really not the system you want after the upgrade, then you really have nowhere to regret it.

Instead, it is better to let the system stay at the second level, which is enough for its own use.

It's not that Lin Yi is timid.

To give a simple example, if the system has its own thinking ability after the system upgrade, or if the system was originally a lurking system, only after he is strong enough, he will obliterate the host and dominate the world on his own. In all words, then it can be said that he was the first victim.

It may be an exaggeration to say this, but it is not impossible to think about it.

After all, the appearance of the system is inherently unreasonable. Who can guarantee that it is not something created by a human with a higher level of civilization than himself, and then thrown to himself?

Of course, this is pessimism, and it does not mean that there will be such an outcome.

Because of this, Lin Yi's heart was so uneasy.

Time passed by minute by minute. When Lin Yi heard that the system upgrade was completed, his spirit jumped immediately. After hearing the two words, his body trembled subconsciously.

Immediately afterwards, he began to perceive whether his body was any different, whether there was any change.

Fortunately, after some self-examination, he did not find any abnormality. He was still the same self before, and there was nothing strange about himself.

So, he immediately asked the system in his mind:

[To be continued. . . .
