Soon, a rusty big iron door appeared in front of Liu Yundong, and a large old iron lock was added to the top of the iron door, and the lock was still rusted on the left and right three layers, and it was estimated that it would be difficult to open it even if the key was found.

The iron gate was covered with dust and cobwebs, and a wooden plaque with several Japanese kana (letters) written in red paint was hung from the iron gate.

Maybe due to time, the handwriting looks like it has been discolored, but the content is still legible, because Liu Yundong had taken Japanese when he was in school, so these kana should not be difficult for him.

"Water Supplies and Epidemic Prevention Department? I'm Cao! Isn't this a bacteriological research institute for children's eggs in Japan? Liu Yundong glanced at the plaque on the gate, and after seeing the meaning, he added to his hatred for this ghost clan.

The heart said that even if he fought for his life today, he would let the souls of this group of murderous demons fly away, which was a death task that Liu Yundong gave himself.

But what about the iron gate in front of you? Look, the thickness of this iron door is at least about one centimeter, and it is also double-layered.

"Invincible Wall Piercing!" Liu Yundong thought of it in a flash.

That's right, he is now a four-star Daoist, and the invincible wall-piercing technique is exactly what a four-star Daoist can control.

It is said in the Blue Book that every time a person at the level of a Taoist breaks through, he will add a technique to the original foundation. For example, when he was in one star, he understood the connotation of the blinding method, and when he was in two stars, he figured out the essence of the martial art "Baguazhang".

Then by analogy, three stars can use the invincible wall piercing technique, and the four-star level should be able to cultivate the five ghosts.

Thinking of this, he suddenly laughed a little narcissistic thief, he was so smart, such a difficult problem was solved by him in three or two clicks.

"Help!" The sad cry for help sounded again, Liu Yundong didn't have time to think more, and quickly urged his mind to run the spell, and with a whoosh, he only felt a huge inertia swarming towards him, and in the next second, he was inside the iron gate.

But at the same time, the ghost king inside also smelled a trace of unusual smell, it was from the opponent's smell, in a hurry, he didn't care about the prey in front of the good meal, and immediately sent his walking corpses to fight to meet him, while he was making all preparations in the back.

"Suzu! Bell! Bell! Bell"

"Not good!"

During the march, the soul bell on Liu Yundong's waist trembled and made a high-decibel crisp sound, and the seal letter in his arms also trembled. Frightened, he quickly stopped and subconsciously took a step back.

Just as he was looking around, he found that the originally flat ground in front of him was unexpectedly rising upward, and a large mound of earth slowly appeared after a while.

Liu Yundong hurriedly took out the yellow talisman and waited for it, because through the perception of the four-star Taoist master, he was shocked to find that under the mound was a group of thoughtless and bloodthirsty walking corpses.

After the mound broke, as expected, one by one, Muna's guys came out of the mound.

"Yo?" After all the walking corpses came out, Liu Yundong raised his sword eyebrows and smiled playfully, because he had seen this group of guys, it was the small group of headless soldiers who had just returned from patrolling the mountains outside.

Looking at the group of fierce guys in front of him, Liu Yundong became relaxed, because these headless soldiers were puppets at best, and they were a little fierce, but their movements were much slower.

Playing dead is not a piece of cake for them, looking at the walking corpses getting closer and closer, Liu Yundong suddenly burst out, and with a few neat turns, he pasted the yellow talisman in his hand on the bodies of all the walking corpses.

As soon as the clouds flowed, the headless soldiers who had been labeled with yellow charms all fell to the ground and convulsed.

Liu Yundong used his ordinary spirit finger to press a little hard at them, and the flames rose up, accompanied by a strong smell of burnt rotten meat, and more than a dozen unlucky walking corpses turned into roasted sweet potatoes one by one, but the taste was a little worse.

When the last vestige of the headless soldier's flesh was incinerated, a dozen milky white "Zhu Yuan" the size of cherries appeared on the charred ground.

Liu Yundong couldn't help but be overjoyed, and hurriedly closed his eyes to absorb more than a dozen "Zhu Yuan" into his body, and after Zhu Yuan finished absorbing, he stretched out comfortably.

If you want to say that the powerful ghost Zhu Yuan has been absorbed before, but it is the first time he has seen so many Zhu Yuan. Although the level of these Zhu Yuan is not high, the advantage in quantity is also commendable.

In fact, this kind of thing is divided into three levels, and every ghost clan has it in its body, not only in the ghost clan, but also in the demon clan.

It's just that the color is different, if you say these walking corpses, they are cherry-sized milky white, and they belong to the lowest-level Zhu Yuan ranks.

Further up the ladder is grape-sized and pink, and the highest grade is reddish and egg-sized. And the Zhu Yuan of the demon clan is mostly black, which is only the difference in size, but its purity is not comparable to that of the ghost clan at all.

After packing up a little ghost, Liu Yundong continued to walk forward.

When he opened the second door, he was greeted by a long and narrow corridor, flanked by wooden doors with signs for each department written in standard Japanese.

The floors were concrete, dusty, peeled walls, mottled moss, and it was clear that no one had been here for a long time.

A cold wind blew, and the smell of formalin potion soaked in corpses wafted in the air. Admittedly, this is supposed to be the laboratory of all evil bacteria.

Imagine that the jars and jars, some reagent bottles, a few alcohol lamps, and a hellish operating table should be like this.

However, Liu Yundong did not choose to open any of the doors, because he really could not bear to see any information about the time when the hateful devils tortured the Chinese.

At the end of the corridor there is an iron door, half smaller than the one in front, but it is tightly closed, and the words "Prison is heavy, idlers are not allowed to enter" are written in large white letters.

After stopping for a moment and listening carefully, there seemed to be thousands of unjust souls whimpering and pouring out inside the iron gate.

But I don't know why they were locked in it for the rest of their lives, so that they couldn't escape from the demon's hands until they died, and they were still suffering inhuman torture in this dark place.

Liu Yundong rubbed his hands, it was obvious that he was already a little impatient, no matter what method was used, this iron door must be opened today, otherwise he would be too sorry for the sentence "I am Chinese".

But at this time, the soul bell in his waist rang again, the decibel was even bigger than the last time, and the seal in his arms was more like it was about to jump out.

No need to guess, there must be a big one.
