In one minute, the four digging beasts dug out an underground tunnel more than ten meters away.

This scene is a spectacle.

Zhao Hao was stunned for a while: "Eldest sister, you graduated from Lan Xiang, right?" ”

The two girls had never heard of Lan Xiang's excavation technique, and looked at Zhao Hao blankly.

Xiao Xia coughed twice in embarrassment, lightly touched Zhao Hao's arm, and whispered to him for literacy: "Boss, this is Annie's gene lock ability." ”

"Can the gene lock summon little monsters?" Zhao Hao was confused.

"There are all kinds of strange things in the evolutionary world, I heard that Anne has opened an S-class genetic lock, and this genetic lock comes with a natural supernatural ability, which is to open the door of the void and summon mysterious creatures......" Xiao Xia explained in a thin voice.

Zhao Hao was suddenly, secretly observing his newly developed SS-level gene lock.

It stands to reason that the SS-level goods should be sharper than Qin Sheng's S-level Eternal Night Withdrawal and Annie's summoning technique.

However, his second genetic lock is very special and will take a while to figure it out.

Ten minutes later, the four digging beasts suddenly turned into bursts of white light and disappeared mysteriously.

"Why not?" Xiao Xia asked with wide eyes.

"I'm sorry, but the creatures I summoned last up to ten minutes." Anne said apologetically.

"I dug more than 100 meters in ten minutes, which is already very powerful, and I can't dig so far in ten days." Zhao Hao comforted, and then said weakly: "It's inconvenient to say, you need a few days to cool down for this kind of summoning?" ”

"It's not a few days, it's an hour." Anne is upright and reveals the secret of her genetic lock.

"Awesome!" Zhao Hao sincerely admired, such a powerful gene lock, the cooldown time is only one hour, which can be called against the sky. He remembered that Qin Sheng's Eternal Night Withdrawal could only be used in the dark, and the cooldown time was about twenty-four hours.

According to this line of thought, if you dig 150 meters per hour and summon ten times a day, it will be 1.5 kilometers, and it is really possible for the girl who crushed Lan Xiang with this excavation technology to dig a tunnel to save the world.

Zhao Hao was very amused and asked, "The problem of digging a tunnel has been solved, but in which direction should we dig a hole?" ”

"There's Dabai, just leave it to him." Scarlett patted the head of the big white bear, and the big white bear also shamelessly rubbed his head against the towering chest of the foreign girl, and the picture was impressive.

Zhao Hao suddenly realized, and there was more hope in his heart.

When it comes to tracking and arguing, bears are better creatures than hounds.

It is well known that bears have more than six times the sense of smell than dogs.

Studies have shown that polar bears can track their prey up to 20 miles (32 kilometers) with their sense of smell.

And the mutant big white bear in front of him is obviously more awesome than ordinary polar bears.

Originally, Zhao Hao's plan A was to evolve to the mutation level, and then wait until the Blood Demon Sword Demon was repaired, return directly to the original way, fly out of the hole, and kill a blood path. This is very risky, according to Xiao Xia, there are a large number of soldiers patrolling outside the mine, and there are snipers lurking in the shadows, even if there is a flying suit, the moment it lifts off, it can be knocked down.

I met two foreign girls today, and he had a plan B, if he could dig an exit in a hidden place, it would be much easier to escape at that time. And Zhao Hao is not dead set on flame crystals, that kind of thing is too versatile and valuable, he wants to see if Annie can dig up a large wave of flame crystals.

Zhao Hao was about to discuss the cooperation plan with the two foreign girls, when Scarlett suddenly covered her nose and said, "You two ...... Don't blame me for being rude, you two are so stinky, can you go wash it? ”

Hearing this, Xiao Xia was embarrassed, and Zhao Hao was even more embarrassed.

The people who got into the pit were covered in dust every minute. And Zhao Hao and Xianyu Xia have been hiding in this pit for more than a week, and the four words of gray face can no longer describe them. In this pit, neither of them had ever bathed, not even their faces. Coupled with Zhao Hao's successful evolution today, his body has been detoxified in large quantities, and he himself can't stand his own taste.

Xiao Xia said weakly: "Drinking water is too precious, we even have a problem drinking water, how can we have water to take a bath?" ”

Scarlett suddenly smiled: "It's simple, follow me." ”

As she spoke, she jumped from the hole in the ground from which she had come.

Zhao Hao and the others followed and found that there was a tunnel dug by hand below. After walking along the tunnel for a while, there was a dripping sound in front of me, and I saw that in the gap in the rock in front of me, groundwater seeped out, and gathered together to form a puddle the size of a double bed.

"Great!" Xiao Xia was ecstatic, threw himself on the water, drank the clear groundwater, and then reminisced: "Yes, the minerals are quite rich, and there is a kind of peasant woman's spring." ”

"Ahem...... Scarlett coughed dryly, and suddenly became polite: "That...... Actually, the water you just drank was the ...... Anne and I took a shower yesterday."

"You said it earlier!"

Xiao Xia's face suddenly turned into a chrysanthemum, and she looked like she didn't believe in love.

Zhao Hao stood aside gloatingly, secretly admiring his wit.

"Wash it, I'll go first." Scarlett put down the words, turned and left.

Zhao Hao took out two plastic buckets from the Ice and Snow Castle, and quickly filled them with two large buckets of water where the rock formation seeped water. After Xiao Xia finished washing, Zhao Hao jumped into the puddle and came ruthlessly, directly dyeing all the pools of water black......

He rinsed with a bucket of water to catch the water that had just seeped out, and finally cleaned himself up completely.

That night, the four of them had a simple consultation, which was nothing more than working together to find a way out. The so-called enemy of the enemy is a friend, and the people who were caught in the pit had a bad relationship with the Higu Legion, and the two sides quickly reached an evil agreement.

From then on, Anne was responsible for summoning the earth diggers to dig holes, and Zhao Hao was doing his best to refine the mutation crystals.

"Eat high-grade mutant flesh and increase the ...... of mutant genes by 3"

"Successfully refining primary mutant crystals, increasing the ...... of mutant crystals by 1 point"

The fifth-layer evolution technique can refine five in an hour, and Zhao Hao's improvement genes are very fast. He could also slow down and look for different mutated jerky from the storage ring to eat, betting on the small probability that eating meat would increase genes.

After a few days, the jerky increased by 20 mutation genes and no longer grew.

Zhao Hao refined 79 primary mutation crystals, and his mutation gene reached 99 points.

Just as he was impatiently refining the 80th gene and trying to reach the full value of the mutated gene, a strange thought came.

"You can't refine it, you need to comprehend ......"

Zhao Hao was stunned on the spot, what does it mean that he can't refine?

What does the so-called "need to realize" refer to comprehending?
