Xuanyuan's sword turned into a streamer of light and stabbed towards the target.

As a fourth-order spiritual weapon, there is no doubt about the power of the Xuanyuan Sword, it has already helped Lin Feng kill many enemies, so Lin Feng is very confident in this sword, even if this iron-backed drilling mountain beast awakens the iron wall ability, but Lin Feng does not believe that the iron wall ability can even protect the chrysanthemum/flower.

But the result was that Lin Feng was dumbfounded, because when the Xuanyuan Sword stabbed the iron-backed Diamond Mountain Beast Chrysanthemum/Flower, that position seemed to be suddenly stimulated, and it closed tightly, actually jamming the Xuanyuan Sword.

Stuck...

Lin Feng didn't dare to look at everything he saw, the fourth-order spirit weapon Xuanyuan Sword could actually be stuck when it generated huge kinetic energy at super high speed...

Lin Feng hurriedly raised his hand and made a move to summon the Xuanyuan Sword back, he seemed to smell the disgusting smell on the Xuanyuan Sword, of course, this was actually just his psychological effect.

What made Lin Feng even more speechless was that this iron-backed Drill Mountain Beast didn't even make the move to look back, because its size was too huge, and the Xuanyuan Sword hadn't really pierced just now, and this kind of damage smaller than scratching was directly ignored by it.

"This is the Iron Wall ability?" Lin Feng exclaimed in surprise.

Xiao Zhi said in Lin Feng's mind: "Yes, host, this is the Iron Wall ability, this awakening ability can make the whole body without the slightest weakness, so no matter whether the host is a thorn chrysanthemum/flower or a piercing eye, in fact, the result is the same, if there is no power beyond the iron wall defense, then theoretically speaking, the creature with the iron wall ability will not suffer any damage." ”

"It's a great ability. Lin Feng was amazed, thought for a while and said: "The iron wall only works on the whole body, right? So what about the stomach, it shouldn't work, right? If it can even work in the stomach, then it's really convincing." ”

"The host, the whole body includes the stomach..."

"Uh, Nima..."Lin Feng was completely speechless, feeling that this iron wall ability was a bit too much.

Of course, Lin Feng will not be reconciled, he still has hole cards that he has not used.

Because Lin Feng is not an ant, the iron-backed drill beast will not take the initiative to eat him, when Lin Feng does not exist, so Lin Feng has enough opportunity to experiment, he tried a few more times with the Xuanyuan sword, and found that no matter how thorny, it really can't pierce the surface of the iron-backed drill beast's body, and the body of the iron-backed drill beast is really the same as the iron-cast one.

The Xuanyuan sword couldn't pierce in, so Lin Feng used the Jindan True Fire, and then found that the Jindan True Fire had a little effect, but it was just a little, if it was usual, the Jindan True Fire would not burn anything, even if it was a sea area, as long as a Jindan True Fire went down, it would slowly burn that domain dry, but the Jindan True Fire burned on the surface of the body of the iron-backed Drill Mountain Beast, and the effect was very weak, as if it would be extinguished at any time, and Lin Feng needed to use the spiritual power in his body to maintain it.

Lin Feng burned the Ironback Drill Mountain Beast with the Jindan True Fire for a few minutes before burning off a piece of skin the size of a palm on the surface of the Ironback Drill Mountain Beast, such an injury was like a human being picking off a layer of dead skin for the huge Ironback Drill Mountain Beast, and it had no effect at all.

This effect made Lin Feng directly furious, and a phantom appeared behind his head, and Lin Feng directly opened the realm of immortality.

As soon as the immortal realm was activated, the iron-backed diamond beast that was eating ants and eating happily seemed to have a feeling, it stopped eating ants, turned its head and looked left and right curiously, but because Lin Feng was in its tail, it didn't see it, and then this guy also had a big heart, and continued to eat ants.

Lin Feng, who had opened the realm of immortality, re-sacrificed the Xuanyuan Sword, just took the sword, kicked it on the ground, and stabbed it towards the abdomen of the iron-backed Drill Mountain Beast with the sword.

"I don't believe even this can't hurt you. Lin Feng said fiercely.

The moment the tip of the sword touched the abdomen of the iron-backed drill-mountain beast, Lin Feng felt a layer of force coming from the tip of the sword, this layer of force was like a membrane, Lin Feng knew that this must be the iron-backed drill-mountain beast's iron-walled defensive power, the original Lin Feng's helpless power did not play a role this time, and the tip of the sword directly pierced the membrane.

"Damn..."

Lin Feng only had to shout to lean, and even the sword entered its body directly from the abdomen of the iron-backed mountain beast, and the stinky blood slashed its head and covered its face.

"Huh...," the iron-backed beast roared.

Although Lin Feng's body size was like a needle compared to it, even if it was a needle pierced into the body, it would definitely feel pain, not to mention that Lin Feng had used a great force just now, and this power took Lin Feng to rampage through the body of the iron-backed drill-mountain beast, and some intestines and blood vessels in the iron-backed drill-mountain beast's body were pierced.

The iron-backed beast that felt the pain no longer wanted to eat the ants, it felt the pain, but it didn't know what was happening, so it became furious, scratching its claws, flicking its tail wildly, and swaying its head from side to side, and the ant's nest was suddenly shattered by it.

At this time, Lin Feng, who was in its belly, asked Xiao Zhi repeatedly, "Can you collect this guy's elemental bloodline now?"

"Yes, it's already available. ”

"Okay, that's charged. ”

As Lin Feng's words fell, a huge warm current entered Lin Feng's body in the palm of his hand, and then disappeared.

"Whew!!" The Ironback Drill Mountain Beast let out a more earth-shattering cry than before, and the Lin Feng in its body could not see it, and the scale armor on the surface of the Ironback Drill Mountain Beast at this time had become dull, as if it had suddenly changed from a young man to an old man, this was because its elemental bloodline was extracted by the system, and the iron wall ability it possessed also disappeared.

Lin Feng didn't know what was going on, but he felt that where the Xuanyuan Sword passed, the blocking power in front of him became extremely small, so just in an instant, Lin Feng felt a light in front of him, it turned out that he had already drilled out of the body of the iron-backed drill mountain beast again, but when he went in, Lin Feng drilled in from the abdomen, and when he came out, it was from the back, which was equivalent to drilling a hole directly into the iron-backed drill mountain beast.

The aura in Lin Feng's body in the air shook, and the blood stains on his body were scattered, and when he looked back at the appearance of the iron-backed drilling beast, Lin Feng was stunned: "Is this guy so unscrupulous, why does it look like he is about to hang up?"

"Host, its elemental bloodline has been taken away, and its strength is not one in a hundred, in addition, it is estimated that it has lived for a long time, relying on the elemental bloodline to maintain a strong vitality, and now that the elemental bloodline has been taken away, it has directly entered the mourning period. ”

"Oh, I see, I thought I killed it. ”

Just now, the majestic iron-backed diamond beast was lying on the ground at the moment, and it was difficult to move its body, some ants had climbed onto its body, gnawing its flesh and blood, just now the iron-backed diamond beast devoured ants, and now it is a swarm of ants devouring it, it is really feng shui in turn.

But this is the law of the jungle, the weak eat the strong, just now the ants are weaker than the iron-backed driller, so they can only become food, and now, the iron-backed driller beast has become weaker, and it can only become food.
