I am doing scientific research in Douluo

Zheng Zhan, the chief referee of this competition, is a powerful ninth-level defense system soul instructor.This was Xu Ling and others' impression of the referee, but Xu Ling and others did not expect that Zheng Zhan, who had a very high status in the Sun Moon Empire, was a member of the Empire's worship hall.

Moreover, Zheng Zhan is a strong man, he only recognizes the country, not people, so he was not involved in the internal struggle of the Sun Moon Empire.In addition to surviving, he was also appreciated and trusted by the crippled prince.

That's why Zheng Zhan was entrusted with a heavy responsibility by that prince. In addition to serving as the chief referee of this competition, he usually also serves as the security inspection of the treasury!

After knowing this, Xu Ling quickly entered the information for Zheng Zhan to go to the treasury for inspection.So Zheng Zhan entered the small courtyard that was investigated by Xu Ling and others before, and was strictly guarded. After entering the locked house, he even closed the door.

Everyone was speechless about this cautious attitude, but everyone can see it anyway, and there is no difference, but they are just lamenting the professionalism of this referee.

After Zheng Zhan came in, he opened the cabinet door, and inserted a purple key into the upper hinge on the left side of the cabinet.Suddenly, there was a slight cracking sound.The back panel at the back of the cabinet was slowly opened horizontally, revealing a door with a faint light shining inside.

Then Zheng Zhan entered it calmly.After entering, there is a corridor, which actually gives people a very spacious feeling. The corridor is not directly downward, but goes straight forward, surrounded by thick stone walls, all of which are more than one meter thick, even if it is Huo Yuhao, They all find it difficult to directly pass through such a thick barrier.

About ten meters ahead, three doors appeared in front of you.On each door, there are buttons for ten numbers from zero to nine, and a keyhole.

Just when the referee came to these three doors, suddenly, accompanied by a burst of rattling, small holes appeared in the surrounding walls.Ice-cold metal soul guide ray tubes poked out from inside.All angles sealed off all possible dodge space.

Everyone exclaimed, but Zheng Zhan was calm and calm, without any surprise, as if he had already gotten used to it.

"It seems that this is to seal off all the spaces that can be avoided, so that people cannot dodge. Apart from entering the correct number and key, there is probably no other way to open and deal with the current scene." Xu Ling said, Zheng Zhan Action has already begun.

Zheng Zhan entered the password three, seven, four, five, one, six, nine... on the left door.

"Wocao, it's so long, how can I remember it!" Xu Sanshi muttered involuntarily.

Xu Ling quickly squeezed Xu Sanshi's mouth to shut him up. Huo Yuhao is currently concentrating on recording, so don't let Xu Sanshi disturb Huo Yuhao!

Soon after entering sixteen numbers, Zheng Zhan took out the yellow key, went in and out of the door, and turned left for two and a half weeks.

Clang, clang, clang..."

After three soft beeps, the door popped out three inches, and the previously opened soul guide ray holes were also closed.

"Hey——" As if some pressure had been released, the door bounced open.

Jiang Nannan couldn't help admiring: "What a delicate soul tool setup. But this level, if you don't know it in advance, it will be very difficult to pass."

Xu Ling smiled and said: "It's not a big deal, I guess there will be more powerful ones in the future! After all, this level of protection can only be aimed at soul masters below the soul emperor. The real strong can break through with brute force. You have also seen the extent of these organs. We must be cautious when entering this time! If we make a mistake, we don’t have the strength of Title Douluo to forcibly break in, and forcibly breaking in is not in line with our purpose this time!”

At this time, Zheng Zhan also walked to the front and entered the portal.After entering the portal, everyone was surprised to find that it turned out to be a closed space of about [-] square meters without any passages.

But soon, Zheng Zhan took action. In the seemingly sealed room, he knocked on three yellow square bricks on the left wall, three times for the first brick, five times for the second brick, and once for the third brick. .

Suddenly, the airtight room shook slightly, and the door they had entered before slowly closed.A halo of yellow light glows around the top.

Then the airtight room vibrated slightly, and there seemed to be some slight weightlessness.

"This is..., descending?" Wang Dong'er asked.

Xu Ling nodded and replied: "This place has a higher defense than Mingde Hall, and it is [-] meters deep underground. Within a radius of several kilometers, I guess there are all kinds of soul guides at the time of departure. If If you don’t need an elevator to enter, even a nine-level custom-installed soul-guided cannonball probably won’t be able to blow up the defense above!”

It lasted about 20 seconds, and with the vibration of the large elevator again, it slowly stopped.

A voice came from outside the elevator.

"Hey, Supervisor Zheng, why are you here? Could it be that you want to get some kind of soul tool?" A man came up and nodded and bowed towards Zheng Zhan.

"Supervisor Zheng, we didn't neglect our duties. We just had some food and some wine, so we can't miss anything!" A man came out from behind, but he held a bottle in his hand, although he said He just drank a little wine, but seeing the man's flushed face, he must have been drunk a long time ago.

However, Zheng Zhan obviously didn't mean to meddle in other people's business, he just gave a few words of advice, asked for the key from the two, and said that he would continue to check down.

After the keys of the two of them were there, Zheng Zhan walked along the passage on the left, but the way he walked seemed to have changed a little, the pace became much smaller, Huo Yuhao guessed that it should not exceed two feet, otherwise the mechanism would probably be triggered.

Zheng Zhan walked to a gate along the left side.This door is very tall.It is about four meters high and three meters wide.There is no decoration on it, just a hazard symbol.A three-fork keyhole, and a password button with the place above.

Zheng Zhan inserted the key first, but Zheng Zhan fiddled with the key for a long time before inserting it. Huo Yuhao looked carefully, and it was clear that he was reassembling a new key. He used three keys and put them together before inserting them.It seems to be the keys from the previous levels, and a new key that Li Chong put together with a black key!

Insert the three keys, and then enter the password again.This time, there were as many as 32 passwords.Huo Yuhao was concentrating on recording again.

After entering the password, the door opened with a rattling sound.A faint metallic smell has come out from inside.

Xu Ling and the others only saw a super-large warehouse, which could not be seen at a glance. Inside were large boxes placed in different positions, but there was a strong metallic atmosphere, so there was no need to investigate at all. Xu Ling and the others You know, these are all rare metals!

But as soon as Xu Ling and the others took a look, their soul power was exhausted, and they immediately fell into a coma.

The people outside found that the illusion seemed to have been dispelled. Except for the referee, no matter whether it was Ming Yuzong or Tangmen, all the contestants collapsed on the ground and fell into a coma.

In fact, when the game started, everyone noticed something unusual.

The people who didn't know the truth at first only saw a flash of colorful halo, and the competition platform disappeared in an instant, but after a few seconds, they could clearly see a few people again, but they were all motionless. Even the referee is like this.

Some high-ranking soul masters have already seen that Tangmen should be using illusion-like skills, so they didn't bother the people on the stage, and planned to wait for them to wake up from the illusion.

As for the claim that the chief referee also entered the illusion, everyone felt that the chief referee was afraid of destroying the illusion released by Tang Men and others, which would lead to the unfairness of the match, so they did not forcefully break through.

It seems that everyone's self-strategy is doing well!It saves the explanation of several people in Tangmen.
