After Zhao Hai had finished refining all the talismans, he placed the talismans in the holes he had dug earlier. He placed them at a certain angle and was extremely careful even when he was placing them. He did not let anyone else do it.

While he was refining the talismans, Zhao Hai carved a large pile of stone tablets. These stone tablets were all engraved with talismans. They were not big, each of them less than the size of a palm. There was a small hole on each of them, which could be used to thread a rope.

These array plates were all carved by Zhao Hai during his rest at night. Hu Yuan and the rest did not know why Zhao Hai wanted to do these things, so they did not ask.

It took Zhao Hai a few days to place all the talismans into the hole he had dug. There were a total of 365 talismans, and he could not make the slightest mistake in the angle. After adjusting the angle, he immediately had people bury the talismans, preventing anyone from touching them.

Five days later, Zhao Hai had finally buried all the talismans. He was only missing the last talisman. It was the largest of all the talismans, and it was buried in a very strange place. Zhao Hai had dug a cave at the highest peak of Demon Island. The cave went nearly 100 meters deep before he put the talisman in. On top of the talisman, there was a piece of golden crystal that looked very beautiful.

The Golden crystal was the traction crystal. It was grown on the small tree in the palace of nature. Now that it had ripened, Zhao Hai took it out to use. After all, the small tree could still grow more.

Originally, Zhao Hai wanted to use the ginkgo tree King as the energy source for the entire formation. However, the natural energy emitted by the ginkgo tree was still limited. It would take a long time before it could meet the requirements of the formation. If he used the ginkgo tree as the energy source now, the defensive capabilities of the mountain-protecting formation would be greatly reduced. Therefore, Zhao Hai chose the traction crystal in the end. Using the traction crystal as the energy source would greatly enhance the defensive capabilities of the mountain-protecting formation. The most important thing was that it could also speed up the growth of the ginkgo tree, allowing the plants and animals in Plant City to absorb more natural energy.

After Zhao Hai put the array into the pit and adjusted its position, he activated the array. As soon as the array was activated, all the array talismans in the entire plant City suddenly lit up. Then, the people in Plant City felt a pressure. This pressure covered them all at once, making them unable to move.

When Zhao Hai saw this situation, he nodded in satisfaction. Then, he picked up the stone cards and gave one to everyone. He had them tie a rope and wear it on their bodies.

When they received the stone cards, they felt the pressure on their bodies disappear. They finally understood why Zhao Hai wanted to make these stone cards. At the same time, they were even more curious about the magic array. They did not expect the magic array to be so powerful. Without the stone cards, they could not even move in the magic array.

After distributing all the stone cards, everyone started working again. Zhao Hai, on the other hand, returned to the cave. He needed a good rest. The past few days had worn him out.

Zhao Hai had just entered the cave to rest when Hu Yuan walked in. Zhao Hai quickly asked Hu Yuan to sit. After Hu Yuan sat down, he looked at Zhao Hai and said in a deep voice, " "He Cao, how much longer do you need to finish setting up the formation on this Island?"

Zhao Hai thought for a moment and said in a deep voice, " it will take about a month. Now, only the defensive array in Plant City has been set up. I want to set up some other arrays in other places on the island. These arrays can be offensive arrays. If you don't have a passage token, you will definitely be attacked by these arrays. &Quot;

Hu Yuan nodded and said, " okay, get those magic arrays done as soon as possible. Then I will call out a few kids and let them learn these magic arrays from you. This thing is too magical. Oh right, I just took a look. The magic array you used in Plant City doesn't seem to be any of the magic arrays in the book, right? "

Zhao Hai nodded, " &Quot; yes, it's not the magic array in the book. I researched it myself in the giant sword. In fact, to learn these magic arrays, the most important thing is to learn the magic array talismans. Magic array talismans are like the words we use, and magic arrays are like articles. When we use magic array talismans to arrange magic arrays, it's like a person writing a list of words. The same words, but the articles written by each person are different. The words are combined in different order. I spent more than a year studying these magic arrays at the giant sword, and I did a lot of experiments to understand this principle. So, the most important thing to learn about magic arrays is not to be afraid of destroying things, because if you don't assemble a magic array well, it may cause an explosion, and the power is very great."

When Hu Yuan heard Zhao Hai, he was stunned. Then, he nodded and said, &Quot; so that's how it is. Good, very good. After you've set up the magic array, you can teach them the magic symbols and let them study it on their own. &Quot;
