Three days later, a crisp sound came from the system:

[Drop~'Initially build your own territory' task is completed, and 10 world coins and 5 diamonds are rewarded]

【Get: World Coin*10】

【Get: Diamond * 5】

"5 diamonds! Enough for me to make something good"

Originally, if it were only 5 diamonds, Chen Jin would definitely make himself a diamond helmet so that when he came out of the ground, he would not be afraid of being killed by touching his head.

but!

"We have to get a diamond pickaxe first and take out the medicine from Future Ren Pharmaceutical Company."

The last time I had a bad diamond pickaxe, which was not hard enough, Chen Jin decided to use 3 diamonds to make a [real diamond pickaxe]

【Ding ~ New Mission】

【Task: Further understanding of zombies】

[Requirement: With your own ability, kill 5 arbitrary evolution zombies with your own hands and remove their energy crystal cores]

【Task Reward: 10 World Coins, Obsidian*5】

【Current progress: 0/5】

[Task description: Zombies have begun to adapt to this world and have begun terrible mutations to figure out their mutated energy sources]

"The tasks released by the system are quite logical. This is to fight with the evolutionary zombies and obtain spoils. Then... how to use this energy crystal core, which is the blood crystal?"

Shen Jin tried it, and even the iron sword could not break the crystal.

"Does it really take care of it if you really have to eat it? But... it won't get stuck in your throat so hard?"

"By the way!"

Shen Jin pinched the crystal core the size of a soybean in his hand and came to the [Synthetic Platform].

A brand new and durable iron sword was put on it, and then the blood crystal was placed on it.

A new iron sword appeared on the right.

"Sure enough! It can be synthesized!"

【Iron Sword (Energy Strengthened)】

【Durability: 1500/1500】

【Energy: 500/500】

[Features: Use the zombie energy crystal core to attach to the surface of the iron sword, adding energy attributes, greatly enhancing lethality, and will be restored to an ordinary iron sword after the energy is exhausted]

【Enchant: None】

Raise the brand new iron sword, with blood-colored breath on the surface, with a hazy feeling of energy standpoint.

Just like an ordinary thing suddenly becomes a magic weapon!

"Good guy, this temperament has improved a little bit."

Shen Jin took it and popped a stone into the ground, slashed it with a sword.

Blood shines on the iron sword, cutting the stone into a great gap.

"Ha! It's not penetrated? But if you have this kind of sharpness and a little more strength, you can cut through it!"

The weapon is sharp enough, but the strength is not enough.

Look at the weapon's durability and energy have dropped by 1 point.

"After 500 swords, you will be restored to ordinary iron swords."

Chen Jin used another blood crystal to synthesize an enhanced iron sword again, leaving it for Yang Ao to use at critical moments.

Take out 3 large pieces of diamonds from the package, sink them into the synthesis table, and combine them with two iron rods to synthesize the complete version of [Diamond Pickaxe]

【Diamond Pickaxe】

【Durability: 5000/5000】

【Features: The pickaxe made of the hardest natural material - diamond, there are few items in the world that it cannot destroy]

【Enchant: None】

The durability has been greatly improved, which also makes Chen Jin relieved. If he digs 1,500 times and then scraps it, this diamond pickaxe would be too luxurious.

"This mission rewards Obsidian, so I will make an enchantment platform and attach durability III to the diamond pickaxe. The durability is probably doubled!"

Chen Jin put the blood crystal and diamond pickaxe on the synthesis platform.

No response...

After trying the shovel, the iron axe is the same, and it cannot be synthesized at all.

"It seems that this blood crystal can only strengthen weapons... Does the system imply that I want to hunt more zombies?"

"Hehe...I don't want to eat Ning's trick! I'll hide and let others kill~"

As for the remaining two diamonds, Shen Jin just stayed for use as an enchantment platform.

Chen Jin made a room for Yang Aoxin next door.

When he opened the door, he found that Yang Ao was exercising on a treadmill.

Ashamed...

This is the exercise equipment made by Chen Jin himself, but every day he dug the ground to collect supplies and became a dog, so he kept it in the bedroom to eat dust.

But whenever night comes,

Even if you are tired, Shen Jin will take time to exercise your Qilin arm.

In order to throw, bounce, throw, and lift things faster and more accurately.

So that we can live better!

After arming, the two went to the secret laboratory of Future Human Medicine again.

This time, Yang Ao learned his lesson and made an electric car from a farmer's home in "Crazy Dave's Back Garden". Although it was not folded, it was a bit broken.

But being able to ride by charging is always faster than one's own feet.

The two of them rode all the way, and it took only one hour to get outside the Alloy Beetle Shell Laboratory.

"alert!"

Shen Jin took out the real [diamond pickaxe] and hit it hard!

"Bang bang bang bang!"

The familiar crack finally appeared,

very good!

Sink into the corner of his mouth and raise it up.

Yang Ao looked at the iron handle in Chen Jin's hand, and the blue pickaxe in the transparent place, and couldn't help but sigh in his heart:

"The casting medium has been upgraded again. It seems that the soil-type superpowers that have sunk into the ground have made another breakthrough!

In just 4 days, the superpower can actually shake the helpless mysterious alloy last time!"

Soon, the two of them opened a pit at the bottom of the laboratory.

Chen Jin immediately blocked it with transparent glass, and the two of them looked inside through the holes of 1 square meter.

It's pitch black!

It seems that after the end of the world, there was also a power outage here, and as a secret laboratory, it was naturally completely buried underground and could not shine in at all natural light.

"Did your dad's laboratory still operate before the end of the world?"

"I don't know. I just came back from another place a few days before the outbreak of the end of the world."

"Well... the laboratory seal is so good. Is it possible to avoid this virus outbreak? Besides, your family who are engaged in medicine should have their own antivirus measures, right?"

Although Chen Jin has never seen a pharmaceutical company in reality, he has seen a lot in the movie.

For example...Resident Evil, Walking Dead, Avengers, etc.

Security and disinfection equipment are all advanced!

"Ahem...I'm here for the first time today."

(lll￢ω￢)

Shen Jin took the flashlight and shone it in a few circles.

Scattered experimental table, overturned reagent bottle, large instruments and...

Dried blood all over the ground!

"The people here are afraid..."
