The moon hung high in the sky, and the midnight leaves seemed a little silent.

The current fire shadow building is composed of three floors. The third floor is mainly the fire shadow office and several conference rooms. The second floor is the place to store data and send and receive some emergency information.

For example, the emergency information transmitted by the messenger eagle is basically transmitted here, and then directly transmitted to Huoying through analysis.

The first floor is where all kinds of office workers work.

In the building, in addition to the fire shadow office, it belongs to the secret room deep in the reference room, which stores the most Ninja data.

Only Huoying or ninjas approved by Huoying can enter it to consult materials or learn ninja.

After entering the building, Fuyue went straight to the second floor, from the Yu Zhibo family to the Huoying office building. In order to prevent being found, Fuyue still walked on the ground and circled many buildings for nearly two minutes.

The invisibility of black fog can only last for five minutes at a time. After five minutes, kaleidoscope needs to be used again. Now kaleidoscope is a great loss to Fuyue every time it is used.

Light the ground under your feet and appear on the second floor silently.

Two footsteps appeared in Fuyue's ears from far to near. This was the patrolman inside the fire shadow building. The light of a flashlight appeared at the corner of the corridor, directly passed through Fuyue's body and shone on the wall behind him.

The corridor inside the Huoying building is not wide. Two people walk side by side, almost filling the whole corridor. Fuyue gently jumps up, clings his body to the roof, advances slowly, and crosses with two patrols.

The writer's eyes scanned around, and several ninjas hidden in the dark appeared in the writer's eyes.

The security situation inside the building is no secret to Muye's big family, and there are guards on patrol.

The Ninjas guarding inside the fire shadow building are divided into two teams. One team is responsible for patrolling in the open. Like these two ninjas, there are ninjas hiding in secret places to monitor.

Most of the bright ninjas are regular ninjas, with some guard members, while the dark ninjas are led by dark members.

Looking at the far away patrolmen, Fuyue jumped gently from the roof and turned the corner in front to the reference room. There were no ninjas stationed in the reference room, but the patrols were dense.

Fire, wind, earth, water, thunder, rain, grass ~ ~, the whole reference room is divided into multiple areas according to the situation of each country. Fuyue readily takes out a scroll from the Tuzi area and looks through it. It records the specific data of a place called Hongyan town in the land country.

From delicious food and snacks to local customs, there are detailed records, and there are recent intelligence supplements in the rear, including the recent large and small affairs in the town.

Fuyue believes that as long as he turns himself into a familiar face of Hongyan Town, he can completely disguise himself as a local resident of the town according to intelligence. This is also the most commonly used means for spies from all countries in the world.

Especially in villages and towns that have experienced war, some spies trained since childhood can completely disguise themselves as war orphans by keeping these materials in mind. This is also the reason why orphans outside can not be easily accepted by tolerance village. Even if they enter tolerance village, they will be under surveillance all year round.

Fuyue gently put the data on the bookshelf. Two ninjas with animal masks flashed into the reference room. This is the member of the dark Department responsible for dark surveillance, who conducted a routine inspection of the reference room.

The empty reference room has nothing suspicious except rows of bookshelves.

After the two dark parts disappeared, footsteps sounded again in the distance and gradually approached the reference room. Fuyue went directly to the reference room. The kaleidoscope opened again, and a black fog added to the original black fog to prolong the stealth time.

As Fuyue was about to make a move, two regular patrol ninjas gradually approached. Finally, they walked into the reference room, and flashlights continued to sweep every corner.

"Everything is normal. Let's go."

"OK."

The sound of footsteps faded away. For Fuyue, these patrols posed no threat except to delay him a little time.

He has come to the last room. The lock on the door is not complex. Open the lock and separate a shadow body. The body enters the secret room. The shadow body locks the lock, and then turns itself into a data scroll and hides it in the bookshelf.

Although the interior of the secret room is not large, it contains most of the top secret materials of Muye and many five element evasion techniques.

Although it can not be compared with the place where sealed books are collected, it is also enough to meet Fuyue's current needs.

The writing wheel eye sweeps through the secret room. Although it is in the dark, it can see the handwriting clearly.

Fuyue is not very interested in some top secret information. His understanding of the tolerance community even exceeds the shadow of each tolerance village. There is plenty of time to understand these top secret information in the future.

He went to the bookshelf where Tu Dun Ninja was collected and looked at the scroll above. Fu Yue narrowed his eyes. There were not many scrolls about Tu Dun either.

Fuyue took down a scroll that said the essence of the nature of the earth. It said that the author was an ape flying day chopper. However, Fuyue looked at the old and new degree of the scroll and had written it for at least four or five years.

The contents on the scroll may not be comprehensive, and there are even loopholes, but it is a good reference for today's Fuyue. The latest insights of the three generations should be in the Huoying office.

Fuyue began to see from the beginning of the scroll. These scrolls were not written in a short time. After years of accumulation, a little record was formed to form the current scroll.

And there are positive contents in front, and it will not be long before it begins to become uncertain.

Fuyue saw such a passage: Yanyin village inherits explosive Dun and molten Dun, earth mines form explosive Dun, and earth fire forms molten dun. In my opinion, earth fire can also form explosive Dun, because both fire and thunder have some violent nature, and the rage of fire should replace the rage of thunder. [the explosive Dun here is the mine fist of Shou, not Didala's detonating clay]

Then he denied the previous words in the rear: the fury of fire and thunder is completely different. Although they all have the nature of fury, fire is more inclined to the fury of combustion, and combustion needs another nature of fire, high temperature and heat.

Once the nature of high temperature and heat is released, the fire earth forms a melting Dun before it forms a blasting dun.

Fuyue doesn't know how long it takes between these two paragraphs, but he can feel that the three generations have greatly improved their understanding of the five element escape technique.

And there are many guesses about the blood following limit. Although they are all guesses, they can provide Fuyue with a lot of guesses.

Although the three generations of five element escape did not integrate the blood inheritance boundary, few people in the whole tolerance boundary can surpass his right in the achievement of five element escape, including many owners of blood inheritance boundary, who may not have a profound understanding in theory.

After all, many blood successors do not create their own blood, and then inherit it through blood. Once they wake up, they will be born.

PS: make up for yesterday's update. In addition, the black fog stealth in front may not be very clear. I'll explain it here.

Black fog is invisible after stealth. All objects covered by black fog can be invisible. In fact, this ability is very strong. You book friends might as well open your brain hole and imagine.
