The black fairy paper crane, fluttering its wings, and adding the wish power of a whole wish power bead, can only fly more than a mile away. Pen % fun % Pavilion www.biquge.info

And from the place where Lin Ye was to the Li Mansion, it was five or six miles away, if you counted the size of one or two miles in the Li Mansion, it would take at least seven or eight miles of distance from the Immortal Paper Crane Fei Ge to be able to complete Lin Ye's monitoring needs.

"What should I do? My current soul power can't exert the wish power on the fairy paper crane at all. ”

Looking at the upgraded fairy paper crane in front of him, Lin Ye fell into distress. Although the speed of his Heavenly Soul cultivation is not slow, it is still relatively difficult to quickly improve to the point where he can apply two or even three Wish Power Beads to the Immortal Paper Crane in a short period of time, and it will take at least a month or two to reach the realm of night travel.

"The production of the fairy paper crane is very simple, once it has my essence blood as a guide, it can fly around the range around my essence blood, otherwise if it flies out of this range, it will not feel my position at all, and it will not be able to fly back. The second is to have the power of desire as the driving force of flight, the more power of willingness, the farther it will sense my location. But now, since I can't think about the power of willingness, I can only consider other methods......"

Picking up this fairy paper crane, Lin Ye pondered, "Otherwise, I will secretly go to the periphery of the Li Mansion, and then release the fairy paper crane, in this way, the entire Li Mansion should be within the flight range of the fairy paper crane." ”

This idea was just proposed, but it was immediately rejected by Lin Ye.

"No! It's curfew at night, and it's almost all the guards patrolling outside. If I sneak out, I'll probably be discovered. Besides, today, the Seventh Prince Chen Xi inspected our Yuanfeng City, I am afraid that the guards of the curfew will be even stricter. ”

Thinking of this, Lin Ye dispelled this thought. However, this thought inspired Lin Ye, and an inspiration suddenly moved in his mind, recalling a strange story of "Beacon Tower" recorded in "Persona of Boqing".

This anecdote says that in ancient times, the martial arts and immortal paths of the human race were still only in the toddler stage, and many spells and supernatural powers had not yet appeared. In particular, only a few people can master some magic powers that can be transmitted for thousands of miles, and it is very difficult to transmit messages over long distances, and they can often only be transmitted by post stations and post soldiers. As a result, messaging is untimely and insecure.

Especially on the border of the country, at that time, within the entire territory of the human race, not only were monsters rampant, but also divided into many small countries, and conquest and invasion between various countries were almost commonplace. Therefore, in order to convey the news of the enemy's invasion in a timely manner, many small countries that were divided at that time built beacons on the edge of their borders. Once an enemy army or sign of an invasion is detected, the guards of the outermost beacon will light the wolf smoke on the beacon and pass it out one by one.

In this way, even in the capital thousands of miles away, the king in power can receive the news of the invasion of foreign enemies in time, and also use the beacon fire to send a message to meet the enemy.

The ancient "beacon tower" is no longer needed and does not exist in today's Great Qin Wu Kingdom, but the role of this beacon tower reminded Lin Ye of his immortal paper crane. There seemed to be a slight connection between the two, and Lin Ye pondered, could he also use the method of the beacon tower to unite many immortal paper cranes to achieve the purpose of expanding the detection distance of immortal paper cranes?

"The beacon is constantly transmitting messages through wolf smoke that can be seen from a long distance, and each of my fairy cranes must rely on my essence blood to sense the location. Although there are similarities between the two, they are ...... But one thing is fundamentally different. The beacons are all the same, and many can be built at intervals. But I don't have the skills, every fairy paper crane must rely on sensing my breath to determine the position and direction, I can't put myself there every mile away, right?"

Thinking carefully about the principle of this beacon, Lin Ye always felt that it was just a little bit short, and he could come up with an appropriate way. He looked at the fairy paper crane, and then at the finger that he had just pricked out with a needle, and suddenly he had an idea, patted his head and smiled:

"Haha! Why is my brain so inflexible? Although I am a person who lacks skills, the fairy paper crane only senses my breath, and I can completely replace myself with essence blood. As long as I put a fairy paper crane every other mile, and put a drop of my essence blood on the body of the fairy paper crane, isn't it equivalent to a 'beacon tower'?"

Thinking of this method, Lin Ye said dry and dry, and immediately folded ten immortal paper cranes in one go, according to Fang Cai's method, each immortal paper crane consumed a wish power bead, and a drop of his essence blood was dropped. Then, in addition, Lin Feng stored a drop of his own essence blood on the five immortal paper cranes in them, which was used as a "beacon tower" for the positioning of other immortal paper cranes.

In this way, Lin Ye was now equivalent to making eleven immortal paper cranes, and five of them had an extra drop of essence blood on their bodies for positioning their breath.

"That's it, it's up to you whether this method works or not. The first fairy paper crane, go to ......"

Lin Ye's Heavenly Soul gave the order, and the first immortal paper crane that was a beacon tower fluttered its wings, flew out of the window, and flew directly towards the direction where the Li Mansion was located in the south.

"Okay! The first beacon tower is already in place, and the second fairy paper crane is going to ......."

Although Lin Ye's cultivation is too low now, the refined Immortal Paper Crane cannot sense everything around the Immortal Paper Crane in real time, and can only be sensed from the Immortal Paper Crane at once after the Immortal Paper Crane flies back. However, he could still faintly feel a hint of the situation in the vicinity of the Immortal Paper Crane, as well as giving a rough order to the Immortal Paper Crane.

The second fairy paper crane also flew out, and the distance it flew out of one mile was still within Lin Ye's control and feeling, and then after crossing the fairy paper crane that was the first beacon tower, Lin Ye's mind suddenly lost the position sense of this fairy paper crane. Because this immortal paper crane had already flown out of the sensing range between it and Lin Ye, but just a moment later, Lin Ye immediately sensed its location through the first beacon tower that was used as a beacon tower.
