"Did it work? That's great. ”

Hao Yu just shouted in surprise here, and Guo Huitong's surprised voice came from not far away.

When Guo Huitong approached, Hao Yu immediately pulled her, with a happy face, and walked towards the place where a pile of rubble was piled up, seeing that the smoke and dust had not dispersed, he waved his hand to stir up a strong wind, blowing the smoke and dust into the distance, and after standing in front of the gravel pile, Hao Yu was like offering a treasure, and said to the girl next to him: "Now, you and me, find an exit, if my previous induction is not wrong, the way out is within this range." ”

Hao Yu stretched out his hand and drew a small circle above the gravel pile, enclosing a range.

"Hmm!"

Smiling sweetly at Hao Yu, Guo Huitong nodded, and then leaned out of his soul consciousness and sensed the range that Hao Yu had just delineated.

"Found it! There's an energy node here, huh? How did the energy node move its location? underground?"

It was only a minute, Hao Yu and Guo Huitong on the side looked at each other and smiled, and the two of them pointed at a place within the range that Hao Yu had circled before, but soon! Hao Yu frowned again.

Whoa!

Sensing the fluctuating aura of the energy node flashed under the gravel, Hao Yu waved his hand and swept a large pile of stones in front of him, and swept them aside, and when he followed the energy fluctuation induction, Hao Yu found that the energy node seemed to be underground, and there was exactly the position where the long stone block stood before.

"Down here, dig up and see. ”

Guo Huitong also sensed the breath, without waiting for Hao Yu to make a move, the girl took the lead, only to see the energy breath in her hand flashed, and a convenient shovel appeared, only to hear a crisp sound, the shovel in Guo Huitong's hand, shoveled down against the ground, but only brought up a little smoke and dust, which made Guo Huitong very angry, she was already impatient, grabbed the steel shovel, lifted it high, and shoveled it to the ground again, ding! This time the crisp sound was louder, and the smoke and dust stirred up more, but it still failed to shovel into the ground.

When the smoke and dust cleared a little, Guo Huitong and Hao Yu both widened their eyes and showed surprise, they saw that the steel shovel in Guo Huitong's hand was missing a large piece, which was damaged during the previous shoveling operation and the collision with the ground.

"How can this ground be so hard? Could it be that the ground in this secret space is different from the ground on Earth? I'll try again. ”

Guo Huitong said in surprise, stepped out, came to a place about ten meters away from the mountain, used the broken shovel in his hand, against a piece of ground with grass and trees, and another shovel, only to listen to the sound, the steel shovel was very easy, and the shovel went into the ground, because the girl used too much force, the entire shovel body, all into the ground, leaving only the stainless steel shovel handle still exposed.

"Only this little piece of ground is extremely hard. After trying several more places, Hao Yu looked at the dark ground under his feet and said.

Under the long stone before, a piece of ground the size of a zhang was dark, Hao Yu tried to bombard it with his fist, and found that this small piece of ground was actually harder than the previous black stone.

Next! The two of them continued to attack this small piece of ground, what sharp blades stabbed, what shells bombarded, and even equipped with combat mechs to attack the ground, in short, they tried all the methods they could think of, and finally! Hao Yu and Guo Huitong sat on the ground discouraged, panting, full of helplessness, looking at the small piece of ground, shaking their heads and sighing.

"How about we dig out this piece of ground in its entirety?" After resting for a while, Guo Huitong suddenly said such a terrible idea.

At first, Hao Yu was really stunned, but soon, he accepted the idea, so the two of them let go and started to dig outside the edge of the dark ground, not to mention! It was quite smooth, the progress was gratifying, it only took about half an hour, and the two of them dug out a big hole more than ten meters deep on the periphery of the dark and hard ground, but they still couldn't see the end of the dark stone.

"It's endless, it's all dug so deep, why is it still this annoying color?"

Guo Huitong, who was angry, shook his hand at the dark stone is palm, in addition to knocking down a piece of soil, even the fragments of the dark stone failed to fall a piece, but his hand was slightly painful, Guo Huitong had to continue to dig down.

This digging took more than an hour, and when he dug to a depth of more than 30 meters, he found that what he saw was still dark, so Hao Yu decided to slow down for a while: "It's not a way to dig like this, Huitong! Let's take a rest first." ”

"Then I'll call Yu Ting and them, there are many people and great strength, we are tired of digging, change them. ”

Hao Yu didn't have time to say anything, Guo Huitong flew out of the deep pit, and flew towards the place where Fu Yuting and the three of them were practicing in retreat.

Jumping to the ground and sitting cross-legged on the dark stone, Hao Yu tried to sense it, and soon found that the energy fluctuation similar to the energy node was about a meter under his feet.

"Two seniors, this kind of stone, does it have to be my physical strength to reach the emperor level before I can break it?" Hao Yu suddenly remembered to ask the two ancient predecessors of the Soul Refining Ding Crystal Soul Tower for advice.

Soul Refining Ding's words were always so unkind: "Since you thought of it, why don't you hurry up and practice?" ”

On this night, sitting in the cabin, looking at the glimmer outside the porthole, Hao Yu sighed and said: "If you want to raise your physical strength to the emperor level, how easy is it......? Well, wait, I can also use the demonic energy stored in the dantian, why did I forget about it?"

With the support of the massive amount of demonic energy in the dantian, Hao Yu's cultivation of refining the body bones went very smoothly, but it was inevitable that he would be overwhelmed by the powerful pain, many times! Hao Yu opened his eyes from the pain and sweating profusely.

At the suggestion of Guo Huitong, the four of them continued to dig down, after a few days of fighting, they only dug to a depth of nearly fifty meters, to this depth, the four of them found that it was really difficult to dig down, often spending an hour, not necessarily able to dig an inch deep, not to mention, the digging tools are constantly destroyed.

"Don't dig it! It's so hard, it's clear that it's a pit for us, hmph! I'm tired of Miss Ben, it's up to Hao Yu, I hope he can successfully improve his physical strength. ”

At noon on the fourth day, Guo Huitong chose to give up, as for Fu Yuting and the three of them, they were already tired enough and were resting.
