And the giant tower was cut in the position but was unscathed.

"What?"
Black Rosa looked at her face with horror. This is her strongest blow. Although it can’t compare with her spell method, if direct attack is the most powerful one, even the strong in the same order can’t easily pick it up.
However, such a powerful move can’t hurt this giant tower. What is it like?
Yu Guihai was also very surprised at this time. Black Rosa’s power of this blow is not small compared to his ability to blow it with one hand. This kind of attack can’t shake the giant tower, so I’m afraid this giant tower is not everything.
In particular, he didn’t feel the forbidden power from this giant tower, which means that this giant tower may be hard-resisted by its own material against an attack by a strong person at the peak of the true Tao.
So what is this material that is so hard?
Yu Guihai thought for a while and raised his hand. A wave of terror came out from his fingertips and a bright cone of light quickly formed.
"Is this the master’s strength?"
Black Rosa sensed this wave, and her eyes suddenly shrank, and her eyes flashed with horror. Yu Guihai was an understatement, and with a blow, it far exceeded her strongest trick.
At this time, she became more white about the gap between her own return to the sea and her face became more respectful.
Yu Guihai ignored Black Rosa. He kept condensing his fingertip light cone. When the light cone was condensed to the strongest, it suddenly spiraled and launched. The light cone suddenly exploded on the wall of the giant tower like a disease.
Rumble ~ ~ ~
A deafening horror ring suddenly gave a terrorist impact, which swept out from the explosion point and swept away the chaotic gas around and blew it into the distance.
But when they looked forward to looking at the giant tower, they found that it was still unscathed.
"This …"
Yu Guihai has some words. This thing is too hard. He can directly kill the peak of the true Tao, but he can also break the giant tower with a trace of oil skin.
"This is impossible!"
I return to the sea to think that it makes sense to say that the black Rosa method breaks the giant tower. After all, she is a weak person in the peak level of the true Tao and is good at incantation.
But he can’t hurt the giant tower with his own hands, so there is a problem.
Yu Guihai does not deny that there is such a hard substance in the world, but it must be rare and rarer than a treasure. He denies that he is lucky enough to meet it casually.
He guessed that nine times out of ten there was another mystery about the giant tower.
Yu Guihai thought for a moment and suddenly looked up and his eyes flashed slightly, then he stepped towards the giant tower.
"Master, be careful!" Black Rosa worry wake up way
"Never mind you stay where you are," Yu Guihai said casually.
He soon came to the giant tower and reached out to carefully touch the rough graininess on the surface of the giant tower, as if he had touched an ordinary rough wall and did not perceive the power to prohibit the fluctuation.
"How strange! Is there any root perception power here? "
Yu Guihai’s eyebrows are wrinkled and his face is puzzled. He can’t detect it in some hidden way, just like blue fat skin, but he didn’t find any fluctuation after touching it with his own hands.
The wall of this huge tower is like a really ordinary boulder.
"What the hell is going on?"
I have some anxiety in my heart, and my hand strength unconsciously increases.
"Huh?" Yu Guihai’s face suddenly flashed a trace of surprise. He hurried to focus on his specialty and saw a clear handprint on the wall.
He quickly and suddenly reached out and poked his finger on the wall of the giant tower and immediately poked in and poked out four deep holes.
Then suddenly I grabbed a big stone from the wall.
Yu Guihai then used various means to test the stone for a long time before he looked up and his face was suddenly enlightened.
"That’s so!"
At this time, he finally figured out the secret of the material of the giant tower. The stone body of the giant tower is very hard. Although the boulder in his hand is like cement, it is difficult to shake the strong roots. For example, Black Rosa came and tried it. Her fingers were punctured and no stone powder was caught.
However, this stone is not hard, but its resistance to non-physical forces, that is to say, this stone has extremely strong spell resistance and yuanshen resistance.
If the spell, the truth, the realm and the powerful method cause damage, and the psychic exploration is also the same, only a powerful physical body or entity spirit treasure can cause damage to it.
"Rosa, you try attacking Lingbao directly," Yu Guihai said.
"Yes!" Black Rosa stretched out her hand, and a machete was sharper than a machete, and suddenly everything went towards the giant tower.
Sniff ~ ~ ~
A machete cut into the huge tower with a light sound and went deep enough to continue.
"What is this?" Black Rosa asked curiously.
Her attack power this time is not high or low, far less than the previous trick, but it has caused the effect of the previous trick.
"The material of this giant tower is very resistant to special spells, and it can be isolated from the spirit, so it can detect its parts, but this stone material is soft and can be physically attacked and hurt," Yu Guihai explained lightly
"So that’s it!" Black Rosa understood the particularity of the stone, but it created a new puzzle.
"This material is soft? ?”
She looked at her machete and then at Yu Guihai’s hands, like mud balls, pinching stones and suddenly being autistic.
"It seems that we can go in."
Yu Guihai gave me a relaxed smile.
With that, he raised his hand and dug towards the front digging position.
