The medium through which sound travels is not only air, but also in liquid solids, in other words, any substance other than a vacuum can transmit sound.

The reason why the Hundred Miles of Blood Charm Flame Burning Sky was able to block the Black Dragon God's sonic attack was mainly because it burned all the air and formed a vacuum for a short time.

However, the only thing that the Hundred Miles Blood Charm can control is air, but it can't restrict the sound from spreading in the trunk of the Evil Gu Tree, so it stands to reason that we should be able to hear some sounds from the side of the trunk.

Even if the trunk of the Evil Gu Tree was a substance that was not conducive to sound transmission, judging from the sound wave intensity of the Black Dragon God, even if it couldn't pass down decent words, at least it could pass down some simple vibration sounds, but in fact, there was no sound at all.

Looking at the black dragon god roaring in the air, my eyes unconsciously became fascinated, because I saw the flaws of the black dragon god.

From the appearance of the black dragon god and flew to the top of our heads, he just kept roaring to intimidate us, so that we kept resisting, but the black dragon god himself did not carry out any attacks, even the sound waves were controlled by him, and did not come into contact with the body of the unjust Gu tree, which is not in line with the personality of the black dragon god at all, you must know that the black dragon god is a demon alienated by resentment, cruel and ruthless by nature, how could he catch up with us but delay in making a move.

There was only one possibility, and that was that the Black Dragon God couldn't do it, or rather, he didn't dare to do it.

In this way, the Black Dragon God is not unscrupulous about the Unjust Gu Tree, even if he can use the Unjust Gu Tree Forest as a nest to live in, but in fact, he does not dare to provoke the Unjust Gu Tree, and the relationship with the Unjust Gu Tree is a mutual check and balance.

The Unjust Gu Tree knew that he would not be able to defeat the Black Dragon God before he completely evolved into the Gu King, so he would turn a blind eye to the Black Dragon God, and the Black Dragon God also knew that if he fought with the Unjust Gu Tree, it would definitely be the result of endless death, and even if he could destroy the Unjust Gu Tree, he would have to pay a great price, so he didn't dare to provoke the Unjust Gu Tree easily.

This kind of psychology of being afraid of the wolf with a hemp pole has only appeared in the current situation, the black dragon god can fly over the unjust Gu tree, but the unjust Gu tree will not devour the energy and soul in his shadow, while the black dragon god can only roar in the air but does not dare to carry out the slightest attack on the unjust Gu tree, otherwise they will destroy each other's unspoken rules, and it will definitely be a battle of life and death after breaking the peace.

Burst.

At this time, Baili Blood Charm spurted out a mouthful of blood again, and her pale face made the skin transparent, and even the blood vessels inside could be seen.

Seeing that the Baili Blood Demon was about to carve the Burning Sky Rune again, I hurriedly grabbed her hand, and then said, "Don't resist, I'll send you into the Seven-Star Array." ”

"No, I'm leaving, who can help you block the Black Dragon God's sonic attack?" Baili Blood Charm hurriedly shook her head, stubbornly wanting to continue to portray the Burning Sky Rune, I grabbed her hand: "I discovered the weakness of the Black Dragon God, but she is too strong, I can't counterattack you here, otherwise it will hurt you." ”

"But in this forest of unjust Gu trees, you will be sucked into a dry corpse alone." Baili Blood Charm shook his head again and again.

I lowered my head and whispered in her ear: "Baili Blood Charm, I'll be fine, if you delay any longer, there will really be something." ”

Baili Blood Charm was stunned for a moment, and finally nodded, I held her and shrouded her with my heart, and then took her into the Seven Star Array.

"Yanjing, Junwu, fast forward to the Seven Stars Array." Sent in the hundred miles of blood charm, I immediately said hello to Yan Jing Junwen, and then included the two of them in the seven-star array.

"Brother Xu Shan, sister-in-law of the green leaves, I can only let you go in a little more now, and I will send you out when you pass through this unjust Gu forest."

Xu Shan nodded heavily: "Okay, I can't help with Luye, and we don't need to point out the direction now, you can send us in." ”

With a turn of thought, Xu Shan and the green leaves were also taken in by me, and now that the star position is full, I turned my head to look at Baili Xueji, Baili Xueji's face was pale supporting the ice, but he still smiled at me and said: "Qin Ling, you don't have to worry about me, I can accompany you to the last moment, I am already very satisfied." ”

Against the Black Dragon God, I don't have time to take care of myself, once I do it, Baili Xueji will definitely have a dead end if she is not in the Seven Star Array, so Baili Xueji will say such a goodbye word.

"Xue Ji, what are you talking about, hurry up and relax, I'll send you into the Seven-Star Array." I hurriedly pulled Baili Xueji, and then my mind moved, and I heard a loud bang, and the gravel mountain god was released by me, and at the same time, Baili Xueji was also included in the seven-star array by me.

The peak of the Broken Stone Mountain God is thousands of meters high, and after I released him, I stood directly above the kilometer, just staying under the Black Dragon God, and before he could react, he punched out, because the preparation time was too short, I didn't even use Tianmu, and the fist of all my strength had already hit the Black Dragon God's stomach.

Boom, the huge body in front of the black dragon god was knocked out by my punch, I could clearly hear the sound of flesh breaking, on the landing point of my fist, it was covered with spider web-like cracks, black blood and water flowed out of it, and I knew that the more serious injury was not in the flesh, but in the inside.

I got the power of the dragon's horn, and the penetration of the power increased to a terrifying level, and a punch in the cave collapsed the entire dragon's horn land, leaving only a crack on the outside.

The skin and scale armor of the black dragon god are extremely hard, if it was before, at most, the power was hard to hit it, and a blood hole was made, although it was terrifying to look at the wound, but the huge body of the black dragon god, the blood hole dozens of meters deep may not have hurt the muscles and bones, but now it is different, the power of the dragon horns penetrated the flesh of the scale armor, and the power penetrated the deepest part of the force, and this punch did not make the internal organs of the black dragon god hurt.

Roar.

The black dragon god was beaten by my punch and screamed, and his body was like a huge mountain, twisting and falling in the air, and the power that filled it made the heavens and the earth change color, and the rumbling did not know whether it was the wind or the thunder.

"Qin Ling, I can't do it anymore." The Broken Stone Mountain God roared at this time, because his huge body was pressing on hundreds of Wronged Gu Trees at the moment, and one by one the Wronged Gu Trees were crushed to a clicking sound, and many of the tree trunks had already begun to crack, making a crackling sound.

The Broken Stone Mountain God is the only Mountain God in the Blood Prison, and it is unimaginable how heavy the body is, even the Broken Stone Mountain God himself has no way to move, and these unjust Gu Trees can hold the Broken Stone Mountain without being crushed.

But the gravel mountain god didn't feel good either.
