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

This scene is amazing.

Zhao Hao was shocked: "Sister, you Lan Xiang graduated?"

Neither foreign girl had heard of Lan Xiang's excavation technique and looked at Zhao Hao blankly.

Xiao Xia coughed twice awkwardly, touched Zhao Hao's arm gently, and whispered to literate him: "Boss, this is Anne's genetic locking ability."

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

"There are all kinds of strange things in the evolution world. I heard that Anne opened a S-level gene lock. The innate magical power attached to this gene lock is to open the door of the void and summon mysterious creatures..." Xiao Xia explained with a slight sound as if she was mosquito.

Zhao Hao suddenly realized and secretly observed his latest SS-level gene lock.

Logically speaking, SS-level goods should be more sharp than Qin Sheng's S-level Eternal Night Extraction and Annie's summoning technique.

However, his second gene lock is very special and it takes a while to figure it out.

Ten minutes later, the four earth-digging beasts suddenly turned into white lights and disappeared bizarrely.

"Why is it gone?" Xiao Xia asked with wide eyes.

"Sorry, the creatures I summoned lasted for up to ten minutes." Anne said a little apologetically.

"I dug more than 100 meters in ten minutes, which is already very powerful. I can't dig this far in ten days." Zhao Hao comforted him, and then said weakly: "Fang is not convenient to say, how many days does your summoning need to cool down?"

"It takes less than a few days, an hour." Anne was very straightforward and announced the secret of her genetic lock.

"Awesome!" Zhao Hao sincerely exclaimed. Such a powerful gene lock has a cooling time of only one hour, which is amazing. He remembers that Qin Sheng's eternal night withdrawal can only be used in the dark, and the cooling time is about twenty-four hours.

Following this idea, if you dig 150 meters per hour and summon ten times a day, it would be 1.5 kilometers. This excavation technology crushes Lan Xiang's girl, which really has the potential to dig a tunnel to save the world.

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

"If Dabai is here, just leave it to him." Scarlett patted the big white bear's head. The big white bear also shamelessly rubbed his head against the foreign girl's towering chest. The scene made people sigh that people were not as good as bears.

Zhao Hao suddenly realized and had a little more hope in his heart.

Speaking of tracking and defensive positions, a creature like bear is better than a hunting dog.

As we all know, bears have a sense of smell that is more than six times that of dogs.

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

And the mutated big white bear in front of us is obviously more awesome than the ordinary polar bear.

Originally, Zhao Hao's plan A was to evolve to the mutation level, and then wait until the Blood Charm Sword Demon was repaired, and he would return directly, fly out of the cave entrance, and fight out a bloody path. This is very risky. According to Xiao Xia, there were a large number of soldiers patrolling outside the mine, and there were snipers lurking in the dark. Even if they had flying combat equipment, they might be knocked down in the moment they took off.

Today I met two foreign girls. He had Plan B. If he could dig an exit in a secret place, it would be much easier to escape by then. Moreover, Zhao Hao had not given up on the flame crystal. That kind of thing was too widely used and valuable. He wanted to see if Annie could dig out a large wave of flame crystals.

Zhao Hao was about to discuss a cooperation plan with two foreign girls, but Scarlett suddenly covered his nose and said, "You two... don't blame me for being rude. You two are so smelly. Can you wash it?"

Hearing this, Xiaoxia was very embarrassed, and Zhao Hao was even more embarrassed.

Those who entered the mine were covered with dust for minutes. Zhao Hao and Xian Yuxia hid in this mine for more than a week, and the word "smashed and dirty face" could no longer describe them. In this mine, neither of them had taken a shower or even washed their faces. In addition, Zhao Hao had successfully evolved today and his body was detoxified, so he could not stand his own taste.

Xiao Xia said weakly: "Drinking water is so precious. We even drink water is a problem. How can we take a bath?"

Scarlett suddenly smiled: "This is simple, come with me."

As she said that, she had never jumped down the hole when she was there.

Zhao Hao and the others followed and found a tunnel dug out by hand. After walking along the tunnel for a while, there was a sound of dripping water coming from the rocky gap in front of them, groundwater seeping out of the rocky space in front of them, gathering together to form a puddle the size of a double bed.

"That's great!" Xiao Xia was ecstatic and rushed over and lay on the water, drinking the clear groundwater, and then recalled happily: "It's great, the minerals are quite rich, and there is a kind of peasant women's mountain spring to catch their feet."

"Ahem..." Scarlett coughed twice, and suddenly became gentle: "That... Actually, the water you just drank was from 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.

"You guys wash, I'll leave first." Scarlett said this, turned around and left.

Zhao Hao took out two plastic buckets from the Ice and Snow Fort, and then followed the water seepage in the rock formation, and soon filled two large buckets of water. After Xiao Xia finished washing, Zhao Hao jumped into the puddle and became fierce, and directly dyed the pool of water black...

He used a bucket to rinse the water that had just oozed out, and finally cleaned himself up thoroughly.

That night, the four of them held a simple consultation, nothing more than working together to find a way out. The so-called enemy is a friend, the person who was caught in the mine had a bad relationship with the Japanese Dog Legion, and the two sides quickly reached an evil end.

From then on, Annie was responsible for summoning the earth-digging beasts to dig holes, while Zhao Hao worked hard to refine the mutant crystals.

"Eat advanced mutant flesh and blood to improve 3 mutant genes..."

"Successfully refine primary mutant crystals and increase 1 point of mutant crystals..."

The fifth layer of evolution can be refined in one hour, and Zhao Hao can improve his genes very quickly. He can also slow down and find different mutant jerky meat from the storage ring to eat, betting on the smaller probability of eating meat to increase genes.

A few days later, the jerky increased by 20 points of mutant genes and never increased again.

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

Just as he was impatient to refine the 80th gene and trying to reach the full value of the mutant gene, a strange thought came.

"It cannot be refined, you need to understand..."

Zhao Hao was confused on the spot. What does it mean to be unable to refine it?

What does the so-called [need to understand] mean to understand?
