But Yu Shu's sacrifice created a good opportunity for Tian Yong.

After the giant rat removed a paw from him, Tian Yong felt light.

Ignoring the pain in his left shoulder, he leaned sideways slightly, and forced the gap between himself and the giant rat.

Then he stared intently, found his target, gritted his teeth and kicked Yu Shu's knife, and stabbed the entire scimitar into the stomach of the giant rat, causing the giant rat to pause for a short time.

Golden opportunity!

Tian Yong let out an angry roar, pressed his head against the giant rat's chin, let the giant rat scratch indiscriminately on his back, and the knife in his right hand struggled into the belly of the giant rat, and then the whole body desperately drilled into the back of the giant rat's body, and cut a long cut in the abdomen of the giant rat with his knife.

As a result of disembowelment, all the organs in the rat's stomach lost their support and fell down one after another.

And Tian Yong naturally suffered under it, with two gray-white intestines hanging on his body, and the whole person was also dyed into a bloody person.

After the giant rat was hit hard, its blood-red eyes quickly lost focus and gradually dimmed, and finally struggled a few times, lying on Tian Yong's body and no longer moving, and died.

"Hah...... Ha ...... "Tian Yong relaxed at this time, only to feel pain everywhere on his body, multiple muscle strains, especially the arm with the knife, just now in order to kill the giant rat in one fell swoop, the arm was out of strength, so that it is still trembling.

At this time, he didn't even have the strength to push away the giant rat on his body.

"Look, the barrier is fading!" A surprised voice came from afar, "We can finally get out of trouble!" ”

"Great, I can finally get out of this hellish place, that rat is so scary, I don't want to stay in this place for a moment."

"By the way, don't we have to worry about those two people? They're still struggling with the rat, don't they have to save them? ”

"Whoever told them to provoke the rat whether they live or die."

"But they're here to save us......"

"You're stupid, aren't they trying to save themselves? What's more, if you don't have a diamond, don't take on the porcelain work, you have to be sent to death, who is to blame. ”

"Yes, yes, let's take care of ourselves, let's take a walk, run for our lives first."

Looking at the source of the sound, Tian Yong saw that the blue barrier was rapidly fading at a speed visible to the naked eye, and it disappeared after a while.

And as the barrier disappeared, those who had fled before rushed outside, lest they were slowing down.

For a while, the scene was very chaotic.

"Ahem...... "None of the people turned their heads to look at the two of them who were fighting the giant rat to save everyone. Seeing this, Tian Yong couldn't help but be angry, and coughed without taking a breath.

"I'm really blind, how did I save these guys, a group of white-eyed wolves, they didn't even look at it, they only cared about themselves and ran away, if Yu Shu was still awake, he should have fainted again."

Tian Yong was a little embarrassed and a little helpless, but the matter had come to this, and he didn't want to say anything, he just wanted to push the giant rat on his body away first, and he was pressed underneath all the time, a little out of breath.

"Hey, weird, what is this?" Tian Yong noticed something unusual.

Underneath the giant rat, beside himself, there was a small dark black thing.

Tian Yong looked at it intently, and it was actually a heart.

The ground under the giant rat was covered with rat blood, but the heart was not stained with the slightest blood, which was very magical.

The heart seemed to be alive, beating again and again, and it was surrounded by a pale golden mist, which set off its extraordinary.

"What the hell." Tian Yong muttered, he was very sure that there was nothing there before the giant rat died.

Even if he missed something, he could still find such a strange thing, but now that such a black heart suddenly appeared, it was indeed a little weird.

Tian Yong reached out to grab the heart, and just as his fingertips touched the black heart, a thought suddenly flashed in his mind, it was a piece of information.

"The Heart of Black Iron, a first-level key, can be used to activate life force, increase a certain amount of life energy, and can also be used to heal wounds. Note that after the first swallow, there will be 12 hours of slumber time for the activation of the life force, and 6 hours of slumber time for each subsequent use of the key. ”

"Heal the wound!"

Tian Yong didn't understand what the previous information meant, but in the end, Tian Yong was very clear about this effect.

His eyes were fiery as he stared at the black iron heart in his hand, and he was about to use it on his body, when he suddenly stopped again, and turned his head to look at Yu Shu, who was breathing weaker and weaker in a coma beside him.

Tian Yong hesitated for a while, making a tangled choice in his heart, and the effect of the heart of black iron made him very excited.

In the end, he seemed to have made up his mind, and spit out a heavy breath of turbidity, as if he wanted to spit out the unhappiness in his heart, and then looked at Yu Shu in a complicated way, and said to himself: "I, Tian Yong, have all shortcomings, and the biggest shortcoming is that I don't like to owe others." Boy, if it weren't for the fact that you saved my life before you, I wouldn't be willing to give it to you. Alas, this time it's all cheap. But ah, I hope the effect of this Black Iron Heart is strong enough, or I'll cry to death. ”

After speaking, he broke Yu Shu's mouth with his hand and stuffed the heart of black iron into it.

After doing this, Tian Yong took a small rest, so that his weakened arm relaxed a little.

Then, after gaining some strength in his arm, he pushed the giant rat's corpse to the side so that he could crawl out from under it on his side.

However, in the process, his injured shoulder on the other side inevitably bumped, and when he crawled out from underneath, a little bead of sweat was leaking from the pain on his head.

After crawling out from under the giant rat, Tian Yong began to think about his next plan.

Tian Yong knew that after the fierce battle with the giant rat, this place had long been in shambles, and the loud noise made during the previous battle must have already been spread.

Coupled with the strong smell of blood here, if there are monsters similar to giant rats around, then they will definitely be lured over, and the two of them will only become their food in their stomachs at that time.

"It's not easy to stay here, but ......"

Tian Yong smiled bitterly.

He also knows his physical condition, if he just walks by himself, he can still walk, after all, he is just out of strength, just take a break.

But what about Yu Shu, can you leave it here? Tian Yong couldn't do it.

Not to mention that Yu Shu did not give up on himself at the moment of his crisis, it is even more impossible for him to give up on him at this time, and Tian Yong has also fed Yu Shu the heart of black iron, if he wants to go alone, why should he give Yu Shu to eat? Isn't that a waste!

However, Tian Yong has already lost an arm, and he can't take Yu Shu with him on his own, not because he doesn't want to, but because he can't do it.

Just as Tian Yong was having a headache about this, suddenly a timid female voice came into his ears from behind him, and her voice was full of panic: "Excuse me, do you need help?" ”

"Who?!"
