Although the magical eagle could not see the specific origin of the master hidden in Xu Feng's body, it could see what his weakness was.

Brother Shen Diao predicted it well. That guy was the Blood Demon Holy Envoy, a disciple of the Blood Demon Ancestor. He helped the Blood Demon Ancestor come here to investigate the abnormalities that had happened in the Jiangdu area a few days ago. The Blood Demon Ancestor was worried that the heavens and earth would appear in Jiangdu, and the Blood Demon Saint Envoy was his capable disciple.

The Blood Demon Ancestor has always practiced evil ways. For example, they cruelly absorbed the blood of ordinary people to practice.

However, their way of using blood and worshipping laws is essentially different from the Western blood clans. Among the Western blood clans, including vampires, they will directly suck blood and directly use the blood to act as their food and source of power. If there is no blood, including the blood of animals, it is like humans without food.

However, although the Blood Demon Ancestor is also very interested in blood, it is not used to suck it, but to practice it. Therefore, the Blood Demon Ancestor Ancestor's use of blood is actually even more terrifying, because the blood clan created the special abilities that are many times more than mortals, such as strength, hearing and vision, etc. However, after the Blood Demon Ancestor's Ancestor obtains blood, it can evolve into a power that destroys the world. The Blood Clan and the Blood Demon are not comparable at all.

The common point between the two is their sensitivity to blood. When they see fresh blood, they will become very excited, greedy, and have an uncontrollable attraction.

At this time, the fake Xu Feng showed this strangeness, and he saw a greedy look in his eyes, and he shone with his saliva, swallowing his saliva, and he wanted to go over to check it out.

All of this was naturally arranged by Xu Lang according to the arrangement of Brother Shen Diao. He ordered his subordinates to collect a large amount of blood, which were all stolen from the hospital's blood bank. According to the "Seven Stars Nail Corpse" formation taught to him by Brother Shen Diao, it was divided into seven positions and seven small blood piles, and these seven small blood piles showed a unique shape, like the "Big Dipper", or this is the origin of this formation.

Not only that, with blood stains as the outline and blood stains as the line, the "Big Dipper" are connected together to form a formation button that is closely linked to each other.

All formations have a place where the power is most concentrated, which is the location of the "array eye". The array eye of the "Seven Stars Nail Corpse" is located in the middle of the connection between the two stars at the beginning and the end. If the "Big Dipper" is really regarded as a spoon, the position of the array eye is exactly 1.681 to 1, and this ratio is exactly one of the greatest discoveries of human science - the golden ratio.

Of course, Brother Shen Diao is just a carving after all, an animal. No matter how strong his language ability is, he may not be able to tell Xu Lang the exact proportional value, and this value was just developed by Xu Lang.

It was strange that Brother Shen Diao told Xu Lang that the eye of the formation was located on the middle line between the two stars at the end of the Big Dipper. Xu Lang immediately drew a shape diagram of the Big Dipper in his mind and linked the two stars together. He was surprised to find that in fact, this middle point, in terms of the shape and size of the entire "spoon", exactly conformed to the "golden ratio", which made him a little excited.

When people describe beautiful women, they often say that having a devilish figure and golden ratio means that the length ratio of a woman's legs and upper body conforms to the golden ratio. If the ratio of the upper and lower parts of the nose at the entire face conforms to the golden ratio, it is a standard golden ratio face, which is also a standard beauty. Perhaps Xu Lang has too many beauties, so he has such a deep and sensitive impression of the number of golden ratio.

Human science and ancient formations actually collided with sparks of wisdom at this moment, which made Xu Lang magically understand its true meaning by Xu Lang. By chance, he took the fake Xu Feng next to him and came to the eye of the "Seven Star Nail Corpse" formation.

In an instant, the seven stars of the entire "Big Dipper" and the blood lines connecting the seven blood piles flashed with red light. At this moment, the false Xu Feng's resistance to the blood under his feet and around him became weaker. He really had the urge to appear immediately and absorb the blood.

However, the Blood Demon Saint Envoy was not an ordinary person. He seemed to realize it quickly that this was a trap. He seemed to have fallen into the formation of Xu Lang. He hurriedly escaped, but he was stunned to find that his feet could not leave the ground at all. Not only that, just under his feet, it seemed that a pair of hands grabbed his ankles with an irresistible force and wanted to pull him below the ground, which surprised him.

The fake Xu Feng looked at Xu Lang in amazement and said angrily: "Ah, little brat, what have you done to me?"

The Blood Demon Saint Envoy did not know that the location under his feet was exactly where the eye of the "Seven Star Nail Corpse" formation was located, and it was the core of his strength. It would be strange if he could escape from here without his true body.

When Xu Lang saw that the formation had indeed taken effect, he couldn't help but say coldly: "Hmph, you are indeed fake. What kind of thing are you? Why don't you show up quickly!"

The Blood Demon Saint Envoy finally verified his guess. Xu Lang really tried it on him. Although he didn't know what kind of formation he was in, he also knew that this formation was very powerful. If he didn't withdraw in time, he might hurt his soul.

What the Blood Demon Saint Envoy didn't know is that the power of the seven-star nail corpse formation is not only the "seven stars" but the "nail". This is the most critical link of the entire formation. This link naturally requires Xu Lang to complete it in person.

Xu Lang jumped up and flew up and down according to the instructions of Brother Shen Diao. His palms were hitting violently towards the ground. With loud noises, fire lights were like nailing a piece of paper into the wall with nails. Xu Lang's power of true energy was like "nails", and he nailed the "paper" to the ground with force, and the "paper" here was fake Xu Feng.

Fake Xu Feng soon discovered that not only his feet could not leave the ground, but also his hands were difficult to stretch.

After watching Xu Lang's exquisite layout, the blood lights around him were filled with the sky, which made him even more attractive to the Blood Demon Saint Envoy.
