After Zhou Qing left, Jiang Feng stopped moving his hands. Although he appeared quite calm just now, in fact, no one would remain calm if they suddenly knew that they would face such a powerful enemy!

"Are there any problems with the rune refinement and multi-layer distribution?" Jiang Feng asked the flower fairy who was carefully recording the data.

"It's basically completed. It's a pity that we didn't attack the rune, otherwise the Huanglong Group would be nothing but trash!" The flower fairy looked up at Jiang Feng and said unconvincedly.

"Uh, let's get these done first!"

Jiang Feng also hoped to find an attack rune, but it was impossible to find one at the moment, and their current interpretation of the rune was still at the most superficial level.

"Well, but setting up a large force field that can protect the entire castle requires a huge amount of energy. How should we solve this problem?" The flower fairy thought of the last question. Their current plan is to set up a large defensive force field above the castle. This is also the confidence of Jiang Feng!

"I will control the turtle to provide energy." Jiang Feng had also thought about this problem. The simplest way is to let the turtle charge energy, otherwise it would be impossible to do it by relying on manpower even if you die of exhaustion!

"Well, let's start the preparations now! Humph, when it's done, let's see who can beat us!" The flower fairy waved her fist and said fiercely.

"Well, you go prepare the rune drawing, and I'll go purify the secret gold!" Jiang Feng knew that time was running out, and he had to hurry up to complete this task, otherwise he was not sure whether the castle could withstand the large-scale attack from the enemy in the future!

"good!"

This time, Jiang Feng was going to create a rune force field that wouldn't follow the previous method. The secret gold would become the carrier of the runes, becoming the runes themselves, and then melt into the metal of the castle. And even though it was a castle, the other ancillary buildings also needed to be covered by the force field to truly protect it.

With the castle as the center, the layout of the runes needs to be strictly designed. Some runes also need to be arranged on other buildings and city walls, and then connected into a whole through secret gold. Finally, all the rune force fields are concentrated to increase the overall defense of the castle by dozens or even dozens of times!

The entire process began with drawing runes on the original building's surface. Jiang Feng then manipulated the secret gold to form the runes according to the shapes of the runes, melting them into the metal walls. Finally, all the runes were connected together through secret gold circuits. He also established a central hub within the castle to control the operation of the runes, where energy crystals would provide the energy for the entire rune formation to operate!

Except for the castle and the city walls, other buildings will only have runes painted on the top. However, in order to maintain confidentiality and facilitate work, Jiang Feng still notified all irrelevant personnel to stay indoors and not go out at will.

Then the flower fairy began to draw runes on the metal surface of the castle. Because she could easily control the blood forest, she could land anywhere in the air. She could move freely throughout the castle as if flying, so she completed this work very quickly.

Jiang Feng carried a large amount of secret gold with him after her. He and the Flower Fairy also figured out some of the properties of this metal. For example, the purity problem will affect the efficiency of the rune. When the purity of the secret gold is very low, cracks or even breaks will occur when transmitting supernatural energy. High purity can not only avoid these problems, but also improve the efficiency of the rune operation.

Jiang Feng used his metal ability to continuously purify the secret gold. When the purity reached the requirement, he turned it into a one-centimeter-thick metal sheet and covered the runes drawn by the flower fairy. Finally, he melted it into the metal wall in the shape of the runes without any error.

The entire castle has the highest defense level. Jiang Feng and the Flower Fairy used multi-layer rune methods to enhance the defense here, so he and the Flower Fairy did the same work here three times in total!

After the castle was completed, Jiang Feng and she began to draw runes on the city walls. This part is also very important, and can be run independently when necessary, effectively reducing energy loss while playing the greatest role in battle.

The city wall is divided into four sections, and the layout of the runes is the same. The last part is the layout of the tops of other buildings. This part is mainly a defensive force field. The runes are single but the area is the largest!

The last step is to use secret gold to connect all the runes into a whole and connect them to the control room inside the castle. Jiang Feng has prepared several energy crystals. These energy crystals are also controlled by mechanical devices to start and shut down. Jiang Feng set two states, one controlled by Anna and the other manually!

There is a secret gold line under the energy crystal device that is directly connected to the turtle's shell. Jiang Feng can use it to control the turtle's energy charging. Otherwise, it would be impossible to meet such a large consumption by relying on manpower.

After all the runes and connection parts were completed, Jiang Feng began to let the turtle charge the energy crystal.

Soon, under the influx of the turtle's huge supernatural energy, several energy crystals as big as its head quickly turned red and bright, and all the energy crystals were saturated with supernatural energy.

"Okay, stop!"

Upon seeing this, Jiang Feng immediately asked the turtle to stop. If it continued charging, the energy crystal would explode!

"Oh, I'm so hungry!"

After hearing Jiang Feng's order, the turtle stopped charging, but the consumption made it a little hungry again.

"Oh my god! Forget it, let's test the effect first!" Jiang Feng almost fainted when he heard its emotional fluctuations. Does this guy want to eat the zombies to extinction?

"Zhou Qing! Hand out some of the stolen weapons!" Jiang Feng turned on the communicator and said to Zhou Qing.

"Okay, but what do you want this for, Brother Jiang?"
