43   The system is upgraded again

Inside the base.

Mo Shi sneaked back to the corpseyard.

With his strength, Lao Li and Kaixin naturally could not find out that he had secretly gone out.

He returned to the room and took off his color-changing camouflage uniform.

As soon as he turned around, he threw himself on the bed.

His head was swollen.

Feeling dizzy.

For half an hour, use the mental power with high intensity.

His mind power has been overdrawn.

Mind power is not like physical strength.

Exhausted physical strength and recovery potion.

The mind is exhausted, but no medicine can be restored.

Moreover, if you have exhausted your energy, you can recover after a night of sleep even if you don’t have the recovery potion.

However, the mental power is exhausted, but it takes a long time to recover slowly.

He smiled bitterly.

However, he is still very satisfied with his current strength.

One person's power can cover up a million corpses.

I just ask who else in this world can do it?

And he has not yet shown all his strength.

But he did not relax because of this.

The appearance of that beautiful zombie made him alert.

The strength of the beautiful zombie is obviously much stronger than that of ordinary mutant zombies.

Then there are likely to be more powerful mutant zombies.

So I still have to continue to sign in and become stronger.

Faced with those mutated zombies, I not only have to be able to kill them.

Instead, crush them.

Just as I thought of this, the sound of the system in my mind suddenly rang out.

【The system can be upgraded, please ask if it is upgraded immediately】

Mo Shi was happy when he heard this.

Whatever you want is what you want.

It seems that the last time I was after killing a large number of zombies, the system was upgraded.

This time it's still the same.

He immediately said without hesitation:

"upgrade."

【The upgrade takes 12 hours, and during the upgrade, it is impossible to sign in.】

The system reminds.

Then the upgrade began.

Twelve hours later, it was around three o'clock in the night.

The sound of the system suddenly rang out again.

However, Mo Shi had already calculated that the upgrade was completed and was waiting for this moment.

【Upgrade successfully!】

[Reward: 5 brain cell recovery agents.]

[Reward: 10 enhanced Titan Dragon gene enhancer.]

[Reward: 10 pieces of recovery potion.]

[Reward: 5 brain cell enhancers.]

[Reward: 1,000 bloodthirsty corpse-killing knives.]

Seeing these rewards, Mo Shi couldn't help but smile again.

These are all things that I need most now.

When he had a thought, he took out a brain cell recovery potion from his backpack.

This brain cell recovery agent is dark red.

Like the color of wine.

oral.

He opened his mouth and swallowed it.

The next moment, I felt the swelling and pain in my head disappearing quickly.

In just five minutes, I felt refreshed.

He was delighted.

The system's reward this time is considered conscience.

Put away the remaining four brain cells recovery agents.

Then, the enhanced version of the Titan Dragon gene enhancer and brain cell enhancer were injected into them all.

Now I feel that both the mind power and the strength of my body are much stronger.

His strength should be able to break through soon.

After this high intensity of use of mind power, the mind power has been greatly enhanced.

And now these 5 brain cell enhancers have been injected.

His mental power has been greatly enhanced.

This made him feel full of confidence.

At the same time, the system sounds came again:

【1: System backpack expansion. Each grid of the system backpack can store up to 10 items of the same item.】

[2: Sign in to the designated reward system. Killing zombies can obtain evolution points. Evolution points can be used to exchange for the opportunity to redeem the specified reward. Note: When specifying rewards, you can ignore the location. You can only specify rewards that have appeared in the system.]

[3: Event reward mechanism. After checking in for a specific event, you can get relevant rewards.]

There is a little more upgraded content.

For Mo Shi, who is afraid of trouble, he looks a little overwhelmed.

After reading it several times, I almost understood the meaning of the system.

[Backpack expansion] Needless to say.

Now after upgrading, each grid can hold 10 same items.

It can hold up to 1,000 items.

This is better than a personal warehouse.

[Specified sign-in reward], which means that you only need to kill zombies and obtain evolution points.

You can use these evolution points to exchange for the opportunity to specify rewards.

You will get whatever reward you want.

This is quite practical.

[Event Reward Mechanism] means that you can also get related rewards when doing things.

This is easy to understand.

For example, if you sign in after killing the zombies, you can get rewards related to the zombies.

...

It was three o'clock in the night.

Mo Shi quietly left the corpse farm and crossed the base wall.

Come to the abandoned city outside the base.
