The space-time mining vehicle rumbled to the bottom of the "Peace" diamond field, and he had already harvested half a cart full of diamonds, both large and small, and the digging depth was already hundreds of meters deeper than before.

Beside him, the other four miners also had a good harvest, but compared to the space-time miners, the armed miners mined significantly slower by half a beat.

However, as the depth of the mining deepened, the mining speed of the five mining vehicles decreased significantly, perhaps because there were more rocks at the bottom, which brought great difficulties to the mining work, but more and more diamonds were coming out of the mine, and each one was much larger than the upper layer.

However, I don't know why, but the driver of the five mining trucks found that some ice cubes appeared in the soil and rocks below, although they were all fine ice slags, but at this temperature, it was a bit surprising that ice cubes appeared here. And although this is the bottom of the cave, the temperature is not low at all, it is more than 30 degrees, but now, since the appearance of those ice slags, the drivers in the five mining vehicles obviously feel that the temperature has dropped a lot, about 278 degrees, at least four or five degrees lower than before.

This was a very strange phenomenon, but a few people didn't think much of it.

After all, this place used to be a frozen place, and there was nothing incredible about the appearance of ice slag, and they all thought that it was the outside temperature that did not affect the place, which caused some of the ice to not melt.

However, as they went deeper, the drivers inside the five mining vehicles discovered a strange phenomenon.

That is, the ice at the bottom of the mine has changed from the original ice slag to a large block of ice, and the temperature has dropped by about three degrees, which already makes people feel a little cool.

This strange phenomenon made the drivers inside the five mining vehicles frown.

The presence of ice cubes is not a good sign, which can greatly increase the difficulty of mining, and with ice cubes in the way, some small diamonds are even more difficult to spot.

There was no way, the five drivers could only cheer up and carefully control the mining vehicle to carry out the collection work, and try their best to avoid the impact of ice on the mining vehicle.

Fortunately, the mining process went smoothly and the ice did not have any impact.

However, this phenomenon lasted until ten minutes later.

With a "bang", the digging arm of a space-time mining vehicle slammed, as if it had touched something hard.

"Huh?"

The driver inside the space-time mining vehicle sighed softly and looked at a huge oval object on the control screen, his eyes full of surprise.

"What is this? I can't even punch through the drill......"

With that, he immediately manipulated his robotic arm to dig up the dirt and rocks around the oval and move it to the ground.

Opening the door, the driver walked straight down.

Suddenly, a chill hit, he couldn't help but shiver, said "It's cold", and walked towards the oval object excavated by the space-time mining vehicle.

When he got closer, the driver was surprised to find that it was actually a metal jar with various intricate patterns on it. Although it was covered in dirt and looked dirty, it couldn't hide the beautiful lines and golden color of the oval jar's surface.

"It's a strange thing."

With that, the driver glanced around, then greeted the drivers of the other four mining trucks, and dragged the oval-shaped jar back to the ground of the "Peace" diamond field with the runaway mining vehicle.

"Wash it off!"

When he saw this oval-shaped jar, Lu Wu's expression suddenly became solemn, and in a blur, he felt as if he had seen this thing somewhere.

If you think about it, isn't there an oval-shaped jar of about the same size and style in the scientific research lab?

However, the jar was silver, and it seemed to be a petri dish, with an artificial girl in it.

Could it be that this jar is also a petri dish?

Under his command, Red Guard soldiers immediately brought clean water, and then quickly cleaned the soil from the top of the golden oval jar.

In an instant, Lu Wu was sure that this was indeed a petri dish!

I saw that under the sunlight, this petri dish emitted a layer of golden light, and the surface of the unknown metal, the striped road also seemed to come to life, and under Lu Wu's touch, a "buzzing" sound suddenly sounded.

Then, a layer of unknown metal on the surface of the petri dish instantly turned, and in a "bang" contraction, a transparent glass cover suddenly appeared on the surface of the petri dish.

"Sure enough!"

Lu Wu secretly said in his heart Sure enough, looking at the girl suspended in the cultivation liquid behind the transparent glass cover, he took a deep breath and felt that the commander would definitely like this.

And based on the appearance of this petri dish, it is not difficult to guess that this should be a pair with the silver petri dish in the scientific research laboratory, but for some unknown reason it appeared at the bottom of the "peace" diamond field.

If this is handed over to the commander, the latter will be very happy.

Thinking of this, he immediately ordered twenty rocket pilots to send this petri dish back to the floating island fortress and give it to the commander.

And just in case, he also sent the Defender bomber back as a transport plane.

Once loaded, twenty rocket pilots and maintainer bombers took off from the flat ground near the "Peace" diamond fields and headed for the Floating Island Fortress

Soon, the rocket pilots escorted the Defender bombers back to the floating island fortress.

In the main control room, Lu Ping, who was flirting with Yuriko, suddenly received a communication from several scientists in the scientific research room.

"What's wrong?"

Holding Yuriko, Lu Ping connected to the communicator.

As soon as he spoke, an excited voice came from the opposite side: "Your Excellency, commander, great discovery!" What a discovery! ”

The corners of Lu Ping's mouth twitched, these scientists, every time they are like this, there is no time to calm down.

"What discovery?"

Fortunately, the strength of these scientists is still quite powerful, and every time they take the initiative to inform themselves, there will definitely be something big, so Lu Ping went straight to the topic and asked.

"Your Excellency, do you remember the petri dish that was opened from the iron box? We found an identical one! To be precise, it was the mining forces who dug up an identical petri dish in the mine! ”

"What?!"

Lu Ping's eyes widened suddenly, and he asked in disbelief, "Are you sure?" ”

"Sure! Hurry up and take a look, this petri dish looks like it's about to open......"

"Okay, I'll go up right away."

Turning off the communicator, Lu Ping rubbed his temples, trying his best not to get too excited, and then looked at Yuriko and said, "Let's go, let's go up and have a look." ”

"Hmm." Yuriko nodded, and the two walked out together.
