But not being able to clearly feel it doesn't mean that there isn't, although the improvement is very weak, but Lin Cheng is still keenly aware that the fire crystal still has an impact on the improvement of spiritual power, but now he has not found the key because his research on the fire crystal is not thorough enough.

Looking at the giant turtle shell lying motionless on the ground, Lin Cheng frowned, and quickly thought about which part of the other party to cut from in his mind, he honestly didn't have any research on the turtle, except that the other party's carapace was inherently extremely hard, he didn't know its specific structure and weaknesses at all.

"Twitter!"

Suddenly, just as Lin Cheng was frowning and thinking, the giant rat leader who had been hiding in his pocket suddenly screamed twice, and when he heard the cry of the giant rat leader, Lin Cheng remembered that he had almost forgotten the 'culprit' that caused all this in front of him!

"What's it called? Retract and be honest, don't accidentally get killed by a rock for a while, you don't know which rock! ”

Gently patting the head of the giant rat leader, Lin Cheng casually scolded it, and then continued to observe the giant tortoise to find its weakness.

But the leader of the giant rat seemed to be eager to tell him something at this time, seeing that Lin Cheng ignored him, it scratched its ears and cheeks anxiously, and after a while, it saw that a bright light suddenly flashed in its rat eyes, as if it thought of something, jumped out of Lin Cheng's pocket directly, and rushed towards the transparent frost in front!

"Eh, what the hell do you want to do, don't you see that I'm busy?"

Feeling the sudden lightness of his pocket, Lin Cheng, who was carefully observing the details of the giant tortoise's body, frowned suddenly, and looked at the leader of the giant rat who rushed to the transparent frost and chirped something, and asked it impatiently.

But the leader of the giant rat ignored Lin Cheng's attitude, and raised his small paw towards the giant tortoise's carapace, as if he wanted to tell Lin Cheng something, but because he couldn't speak, it chattered for a long time, and Lin Cheng didn't understand what it was trying to say.

Seeing that his physical strength was about to be exhausted again, Lin Cheng, whose face was pale, forcibly held on to the dizziness in his mind, felt out an energy bean, and was about to throw it into his mouth, when he glanced at the giant tortoise below along the claws of the giant rat leader, but was suddenly stunned!

Due to the reason that his vision was blocked just now, Lin Cheng didn't see clearly where the giant rat leader was referring to, and thought that it was only referring to the carapace of the giant tortoise's abdomen, but when he raised his head and changed the position to look again, he suddenly found that the giant rat leader was not referring to the carapace at all, but the thin gap between the upper and lower carapaces of the giant tortoise!

The color of this gap is almost exactly the same as the carapace on the back of the giant tortoise, and the light of this abyss is too poor, he didn't find this detail after fighting with the other party for a long time just now, but because the two sides are now in a 'truce', and his position is higher, he noticed this thin gap!

Seeing that Lin Cheng finally understood what he meant, the giant rat leader nodded excitedly, and then pecked his upper again, signaling him to act quickly without further ado.

Looking at the momentum of the giant rat leader who was eager to roll up his sleeves and go up by himself, Lin Cheng shook his head a little funny, bent down and put it in his pocket, and then his eyes lit up, and the ice wings that controlled the ice armor warrior flashed violently, and flew towards the giant turtle below!

And the giant tortoise, whose head and feet were all retracted into the turtle shell, did not know that the only weakness on his body had been seen through by the mouse that he didn't pay attention to at all, and the old god was still in the carapace where he was located, and he couldn't help himself anyway.

But with the sound of a breaking wind into the tortoise shell, the giant tortoise suddenly felt a little hairy in his heart, and the experience of living for many years made it faintly feel that something bad was going to happen, but because of the trust in his own carapace, although it felt a little bad in its heart, it still had no intention of sticking out its head to take a look.

But as the saying goes, sticking out the head is a knife, and shrinking the head is also a knife.

The giant tortoise has never heard this old saying of Huaguo, and naturally he doesn't know how serious the consequences will be if he keeps shrinking like this!

"Knock ......"

With a heavy landing sound, Lin Cheng manipulated the ice armor warrior to land steadily beside the giant tortoise, looked up at the giant tortoise that still didn't move, and a sneer suddenly crossed the corner of his mouth, and at the same time, he raised the ice crystal giant sword in his hand and stabbed towards the gap under the giant tortoise's shell!

"Ding!"

A sword stabbed down, and the scene that Lin Cheng expected did not appear, and the sharp tip of the sword was against that gap, and it was no longer able to pierce half a point!

"Could it be a mistake?"

Feeling the heavy resistance from the blade, Lin Cheng frowned slightly, and looked down at the giant rat leader, but the giant rat leader was not hit at all at this time, staring at a pair of rat eyes urging Lin Cheng to continue to move.

Thinking that the other party had really not cheated himself since he cooperated with this guy, Lin Cheng nodded, and after slowly retracting the ice crystal giant sword, his arm stabbed forward again, stabbing towards the place he had just stabbed for the second time!

"Roar!!

With Lin Cheng's second stabbing attack, the giant turtle in the carapace finally couldn't help but let out a painful roar, hearing this roar, Lin Cheng was not surprised, and pressed the sharp sword against the gap, and then his arm suddenly forced, controlling the sharp sword to slash in one direction!

"Nourish...... Boom! ”

The sharp tip of the sword made a piercing roar under the friction with the gap, and along with the roar, there was a dazzling spark, and under the slash of the giant ice armor warrior with all his might, the giant turtle let out a violent cry of pain again, and its head suddenly drilled out of the tortoiseshell!

Seeing that the giant tortoise stretched out its head so easily, Lin Cheng became more and more excited in his heart, and after splitting the huge rock summoned by the giant tortoise twice, he grabbed the hilt of the sword with both hands and launched an attack towards that gap for the third time!

"Poof!"

Finally, Zai Lin Cheng stabbed towards the same landing point for the third time, this time he no longer felt the previous barrier, and the huge ice crystal giant sword body instantly sank into the giant tortoise's body!

"Whew!!"

As the ice crystal giant sword pierced into its body, the giant turtle's mouth suddenly let out an earth-shattering and violent howl, and its huge body rushed wildly in the abyss!

"Boom, boom, boom!"

Because the giant tortoise's body was larger than the ice armor warrior, under the crazy collision of the giant tortoise, Lin Cheng, who didn't want to abandon the sword, could only control the ice armor warrior to hold on to the hilt of the sword, and his body was involuntarily hit by the giant tortoise rushing left and right, and it didn't take long for Lin Cheng in the kung fu ice armor warrior to feel that his head was about to be shaken.
