Red Mountain City further north, it will not take long to fly out of the nine-day realm into the vast void.

The speed of the flying boat is more than 1,000 kilometers per hour. It has just been more than six hours since the Winner Baowu incident last night. In other words, the flying boat may have only flown close to 8,000 kilometers.

If the flying boat kept flying north without changing its direction, it would definitely catch up.

Thinking of this, Zhang Tie no longer delays, and once again activates the invisible mirage, his whole person soars into the sky from the canopy of the tree, chasing like lightning in the direction that the owl saw the flying boat left.

When Zhang Tie left, he glanced behind him. A flying boat with the symbol of Wuhuang Temple just flew 500 kilometers away from Hongshan City. It is estimated that it will arrive at Hongshan City in a while. It seems to be Wu The master sent by the Emperor Temple finally arrived...

Zhang Tie was swiftly in the air, flying towards the north, slowly thinking about the flying boat that the owl saw in his mind again, and after magnifying the scene in his mind, he observed it carefully. At this time , That flying boat was Zhang Tie's only clue.

The flying boat that takes away the people in the Yin and Yang gate is the most common type of small flying boat in the world of skyscrapers. The length of the flying boat is only more than 100 meters. It is the most classic flying boat in the world of flying feathers. Whether the shape or performance has been tested in the world of skyscrapers, the manufacturing drawings of the flying boats are completely public in the world of skyscrapers. They can be manufactured in many places. The interior of the flying boats of the flying feather class may be manufactured according to different customer needs. There are some unique characteristics, but in terms of appearance, Feather-class flying boats are almost indistinguishable from each other. This is like the cars of a certain brand and model made by Taixia. The difference in appearance is almost non-existent. , And more importantly, there is no temple or family emblem or flag on that flying boat. Such flying boats can be found in every corner of the skyscraper. Above the sky, there is an average of one out of every five flying boats. A flying boat of flying feather class.

Even if Zhang Tie has the eye of lotus, it is impossible to find such a flying boat 8,000 kilometers away in the sky. The ability of Zhang Tie’s eye of lotus is not so exaggerated. Locking the target at 8000 kilometers away, if the flying boat has just flew away for an hour or two, and it is within 1000 kilometers, it may be possible, but the distance is too far and the time is too long, and it has exceeded Zhang Tie’s maximum ability, Zhang Tie used the eye of the lotus to see that within two thousand kilometers, there were as many flying boats in the sky as crucian carp crossing the river, each flying in different directions. This situation is like finding a needle in a haystack.

But it is not impossible to find a needle in a haystack. The most important point is to remember what the needle looks like so that you can have a goal.

Just like two leaves on a tree, they cannot be completely different or the same. The flying boat is the same. As long as it is a used flying boat, there must be some differences from other flying boats.

Fortunately, that owl has good vision at night. Although the Feather-class flying boat is the most common item, Zhang Tie still found it from the Feather-class flying boat with his extraordinary ability. Three subtle features that can be distinguished-

The first of these features is the fineness of the flying boat. The flying boat looks about 70% new, and the exterior is not painted. Only this feature can compare this flying boat with more than 60% of other flying feathers. Feizhou distinguished.

The second feature of that flying boat is that there are slight deviations in the exposed points of the metal universal mortise and tenon structure of the middle door of the flying boat. This deviation is a slight difference between the manufacturing process and the manual assembly process. Every flying boat has it, and it is difficult for ordinary people to detect it, but if you draw this slight deviation value with two diagonal lines of the middle hatch, the diagonal line becomes a coordinate. The angle deviation of the flying boat becomes an important factor. Characteristics.

The third characteristic of that flying boat is the port side position of the tail of the flying boat, and the friction marks caused by some not too obvious slight friction. The friction marks may be that the flying boat was accidentally unloading. There will be more or less abrasion marks on the unloading port of the tail of many flying boats caused by rubbing.

These are just three features that Zhang Tie found in a short time from the image of the owl’s mind. Although the eyesight of the owl is good, the details that can be seen at night are also limited. If you change it to Zhang In terms of iron, he only needs to take a look, not to mention three characteristics, that is, three hundred characteristics, he can find out, but at this moment, having these three characteristics is enough.

None of these three features will allow Zhang Tie to lock the flying boat, but when the three features are combined, the probability of Zhang Tie locking the flying boat is 90%. More than five, plus the corresponding time and space elements, it is almost 100%.

Zhang Tie flew towards the north in the air, but his brain was also turning rapidly. The map of the north of Jiutian Great Region appeared in Zhang Tie's head for the first time, and Zhang Tie was analyzing it quickly.

The direction of the flying boat is north, but the north is only a general direction. In these few hours, during the flight, the flying boat may adjust its flying direction at any time, but this adjustment cannot be a head turn, because if you turn your head, it will Fly back into the Martial Emperor Temple on the territory of the Nine Heavens Domain. Judging from the process of those people’s raid on the Yin and Yang Sect last night, the person who is the leader is by no means an idiot, and as long as that person is not an idiot, he will never Will make this kind of brain-dead decision to fly north and then turn to the south, because this decision is not a matter of misunderstanding, but a waste of time, so the first direction that flying boat left Hongshan City last night should be The general direction they are leaving.

But the northwest of Hongshan City and Jiutian Great Region is Wu Huangyu.

Are those people from the Wuhuang Temple? Of course not. If the people from the Wuhuang Temple discover that the Yin-Yang Sect is hiding in Hongshan City, they will definitely send a master to conceal it, and then take the Yin-Yang Sect in an open manner without being so sneaky, let alone the Yin-Yang Sect. So many of the disciples were killed in that Baowu, at least they should be arrested. The more people that can be captured alive, the better. Only in this way can they show the power of the Wuhuang Temple, and what happened to the winner Baowu, no matter what Whether the Wuhuang Temple can finally discover the reality of Yin Yang Sect hiding in Hongshan City, this is all fighting the face of the Wuhuang Temple.

Therefore, although those people left northward, they would never go to Wuhuangyu.

In this way, the position of the flying boat at the moment is the left side of the fan-shaped area with a maximum angle of 110 degrees formed by two lines drawn with the origin of Hongshan City and a maximum distance of 8000 kilometers. A line of at most will only pass through the Dragon Emperor's Domain, and the line on the right of this fan-shaped area is at most parallel to the east of the Jiutian Domain, and will not go south...

Zhang Tie thought in his heart, the map of the Skyscraper that he imagined in his mind has become a holographic three-dimensional dynamic map. On the holographic three-dimensional map, to the north of Hongshan City, a huge trumpet-shaped fan-shaped area It has already turned yellow, and at the same time, with Zhang Tie’s thoughts, hundreds of flashing flying boat routes emerge from this yellow fan-shaped area, and those routes correspond to hundreds of destinations of varying distances. , For those destinations, there are various regions and mausoleums in the Skyscraper Realm. The distance ranges from 10,000 kilometers to hundreds of thousands of millions of kilometers. Since that flying boat has left the nine-day domain, it always finds a place to go back. And if you leave from this fan-shaped direction, the ultimate destination of that flying boat can only be one of those hundreds of targets.

Multiply the time that the flying boat leaves Hongshan City by the maximum speed of the flying boat and 70% of the maximum speed, and you will get a range of distance, which is placed on the hundreds of flying boat routes in that fan-shaped area. At the position of the bell mouth of the yellow fan-shaped area on the map of Zhang Tie’s Sea of ​​Knowledge, a more eye-catching oval red airspace appeared. The entire red area was about 8 million square kilometers.

If nothing happened to the moth, then the flying boat is now in this red airspace.

The red airspace that Zhang Tie visualizes in the sea of ​​consciousness continues to expand every second, showing the changes in that airspace over time. If a few more hours pass, the red The airspace of will become even greater, and the various variables that will be generated in it will also be more, but at this moment, this airspace has not exceeded the worst range for Zhang Tie.

Countless flying boats in the air were thrown behind him by Zhang Tie. Under a high speed of nearly 30,000 meters per second, Zhang Tie flew five to six thousand kilometers in just a few minutes, approaching what he had visualized in the sea of ​​knowledge. At the northern edge of the red oval airspace, when Zhang Tie reached this position, Zhang Tie changed his flight direction and stopped flying straight, but began to fly horizontally in a "z"-shaped posture.

For any air cavalry, you know that such a flying attitude is the basic tactical action to search for a fan-shaped airspace. If you search for a circular area, you need to use a spiral flying attitude. Such a flying attitude is equivalent to ploughing the airspace. The same plow came over again.

Zhang Tie was the ancestor of the air cavalry, and he compiled all the textbooks for the air cavalry. This kind of simple thing is naturally handy.

At this time, only Zhang Tie's terrifying flying speed and Lotus Eye could complete this seemingly impossible task of searching this vast airspace in a short time.

While Zhang Tie adopted a "z" posture, he traversed the red oval airspace in the sea of ​​consciousness at high speed, while scanning the flying boats in this airspace with his lotus eyes. .

Finally, just a few minutes later, a Feather-class flying boat that appeared more than 500 kilometers to the left of Zhang Tie's flight path entered Zhang Tie's sight.

Seeing the flying boat, Zhang Tie's eyes condensed, and the three features on the outside of the flying boat instantly matched. Zhang Tie moved directly towards the flying boat. When he flew hundreds of kilometers outside the flying boat, Zhang Tie's Lianhua's Eye brushed once again, and the flying boat instantly became transparent, and in the reinforced compartment at the bottom of the flying boat, Zhang Tie finally saw the captured members of the Yin Yang Sect.

Everyone in the Yin Yang Sect was in a coma, motionless, and locked up in different compartments. Among those people, Zhang Tie carefully distinguished and saw Ji in the same coma. Yuelan and Jiang Ruoxin, until this time, these two women were still wearing men's clothes.

Less than fifteen minutes after Zhang Tie left Hongshan City, he found Ji Yuelan and Jiang Ruoxin.

Seeing that the two women were still alive, Zhang Tiexuan's heart finally let go, and at the same time he proved that his judgment was completely correct. He had picked up the needle that fell into the sea.

The other people on the flying boat, I am afraid they would never dream of it. In this world, there is such a perverted person with such perverted ability. After they have left Hongshan City for one night, that person first flew from Dragon Emperor Realm to nine days. Da Yu, then it took less than half an hour to wipe out all traces of them from the vast airspace more than 8,000 kilometers away from Hongshan City. There were thousands of people coming and going. Locked in the flying boat-Nima, this is simply not human!

Zhang Tie’s figure flew to the top of the flying boat almost instantly, and his whole person was completely attached to the flying boat, observing the movement inside the flying boat, waiting for the opportunity to save people...
