"Da!"

With a soft sound, the handle of the Tiger Spirit Knife in Zhou Yulong's hand split in two, revealing two scrolls that I don't know what kind of leather they were made of. One of the scrolls was engraved with the ancient characters of "Bamen Dunjia" in Chinese, while the other was engraved with some Japanese characters. These two scrolls should be the [Ninja Secret Record] and the [Eight Doors Dunjia Technique] that Izana said.

"You just gave me the scroll, aren't you worried that I won't keep my promise?"

Playing with the scroll in his hand, Zhou Yulong stretched out his right hand, incorporated the two scrolls into his body, and then looked at Izana, whose breath was getting weaker and weaker, and asked, "After all, you are already a dying person, even if I don't keep my promise, you can't do anything about me, right?" ”

"So what?"

Hearing Zhou Yulong's words, Izana smiled hard and said, "People die like lights go out, I just do what I can, as for what happens after my death, what do I do... Besides, I know you're not going to let Hirohito go..."

"It seems that after letting go of hatred, your mind is much clearer."

Seeing the smile on Izana's face, Zhou Yulong smiled slightly, nodded and said, "Okay, I promise you, I will definitely kill them." Anyway... That's what I was going to do. ”

"In that case... Then I can rest assured..."

Hearing Zhou Yulong's words, a hint of relief appeared on Izana's face. At this moment, the power of the angel potion was finally exhausted, and it could no longer support Izana's completely collapsed body. Soon, the aura on Izana's body became weaker and weaker, and then completely disappeared.

"A man who has been imprisoned all his life by hatred... It's sad..."

Looking at Izana, who had a look of relief on his face until death, Zhou Yulong sighed softly. A person has been instilled with the concept of hatred by his elders since he was a child, and you can imagine how painful his life is. But now everything has nothing to do with him, all he has to do is find the so-called Hirohito and kill him.

"Buzz!"

However, just as Zhou Yulong stood up and was about to leave, an extremely thin buzz suddenly came into his ears. Then he suddenly felt a chill all over his body as if he had fallen into an ice cellar, and a deadly sense of crisis began to slowly become strong in his heart.

"That's not right!"

Although he didn't know what was going on, that instinctive sense of crisis made Zhou Yulong uncontrollable and on guard.

"Buzz-buzz!"

"Ahh

"Flax falls!"

Just when Zhou Yulong was on guard, the humming sound gradually became clearer and clearer. At the same time, bursts of terrible screams and screams came from not far away. Hearing the screams of these RB people, the uneasiness in Zhou Yulong's heart became more and more obvious.

The people who let out these screams should be the ninja soldiers who had evacuated not far away, but their strength was not bad, and their endurance was extremely strong. So, what happened to make them let out this unhuman wail?

"Buzz-buzz!"

The mournful wails didn't last long, and as the strange hum grew louder, the wails began to fade away. Soon, Zhou Yulong discovered a strange thing, that is, those distant corpses actually began to tremble slightly.

"Zombies?"

Seeing that the corpses of those ninja soldiers on the ground in the distance began to tremble, Zhou Yulong's eyes sharpened, and he once again condensed the sword of Langnookis and stopped in front of him, and he was fully guarded.

"Bang bang bang!"

However, to Zhou Yulong's surprise, those corpses did not undergo any corpse changes, but after trembling violently, they exploded violently like an over-inflated balloon, turning into countless blood rain and flesh and shooting out in all directions.

"Bang bang!"

With a burst of dense popping sounds, the corpses of the ninja soldiers in Zhou Yulong's distance all exploded, and the coverage became wider and wider. In less than a second, those exploding corpses went from being thousands of meters away from Zhou Yulong to less than a hundred meters away from Zhou Yulong. At the same time, an invisible force also swept through Zhou Yulong's body in an instant.

At the moment when the invisible power swept through Zhou Yulong's body, he suddenly felt the muscles in his whole body begin to tremble violently, and at the same time, the humming sound also became sharp and piercing from far to near.

"Hmph..."

In the midst of the continuous humming sound, Zhou Yulong only felt that the muscles in his whole body seemed to tremble with those humming sounds, and gradually felt broken. At the same time, there were also bursts of sharp pain inside his body, and this severe pain made Zhou Yulong have to snort, and then began to observe his body.

"My body... Unexpectedly... Crashing?! ”

Under the internal vision, Zhou Yulong was horrified to find that the blood vessels and internal organs in his body were actually like the muscles on his body surface, and they continued to tremble with the sound of those buzzing sounds, and the trembling amplitude became more and more intense, and even some weak blood vessels and internal organs began to appear dense cracks, and they were about to completely collapse.

"How is this possible!"

Finding that his body began to gradually disintegrate, a trace of horror appeared on Zhou Yulong's face. You must know that although he converted his metal body into a physical body after Izana's death to avoid wasting energy, even his physical body is far stronger than ordinary steel alloys. However, even the strength of this body gradually disintegrated under the strange hum, and you can imagine how terrifying the destructive power of this strange hum was.

"It's... Sonic weapons?! ”

Feeling that his body was constantly disintegrating under the influence of that strange hum, Zhou Yulong's eyes froze, and a terrible thought suddenly appeared in his heart. As far as he knew, there was nothing other than the legendary sonic weapon that could possess such destructive power and coverage.

Regarding sonic weapons, Zhou Yulong still has a certain understanding. He had seen a record of a tragic incident in France. In April 1986, on the outskirts of Marseille, 20 people lost consciousness while working indoors and 10 in the fields. In a few seconds, they were reduced to bloody corpses. Autopsies found that all of them died of ruptured cerebral blood vessels. It was later confirmed that this was an experimental accident. At that time, the French Ministry of Defense was conducting a sonic weapon test 16 kilometers away from the incident site, and as a result, the infrasonic waves rushed out of the laboratory, killing all living creatures within a radius of tens of kilometers.

And judging from the strange buzzing and corpse explosion in front of them, these RB people are only afraid that it is very likely that they have used sonic weapons!

Thinking of this, Zhou Yulong couldn't help but take a deep breath and reactivate the metal mimicry ability to transform his body into a metal body. In this case, it will be difficult for those so-called sonic weapons to hurt him again.

However, Zhou Yulong didn't know that the sonic weapon used by the RB people this time was not at the same level as the so-called sonic weapon before, and even if he had a metal body, he might not be able to protect his own safety.

"Increase the output of [Raven Tengu]..."

Seeing that Zhou Yulong was safe and sound under the cover of infrasound, the sturdy old man standing on the top of the building in the distance squinted his eyes slightly, and then said in an indifferent voice: "I don't believe it, his body is really King Kong's incorruptible body!" ”
