Mu Lan already made a triple layer around the castle when she created another one around the island. Each layer was stronger than the last one and in between the layers, there was no wind. It meant that there was no gas either, as a result, if there was any living being in between the layers, it would die in lack of oxygen.

Of course, Mrs. Li didn't know that. But she guessed another thing. She asked aloud, "How come this castle is being protected? Don't tell me there is someone in the castle helping you out. Another Cobra? Those b****ds! They are helping you! It's not that you have the power but it's them. I'll crush you right in front of them and then I'll attack them."

"You sure have a big dream. Careful what you wish for." Mu Lan smirked. Her red eyes glowed.

Mrs. Li screamed, "You think you can defeat me? Take this!" She used more of her power and let hundreds of snakes come out and attack Mu Lan from everywhere. At that same time, she used thousands of snakes to strike the castle.

Mu Lan created a layer around her so that the blood of the snakes couldn't splatter on her body. She looked behind to see the situation of the castle and her eyes widened. The snakes were trying their best to cut through the barrier she put around the castle. Those who were entering were dying in less than five minutes but they still followed their orders.

'Wait a second!' Mu Lan started to think, 'The snake consumes 5.12 ml of oxygen with each breath or 0.077 liters per minute. Therefore, the snake would live for around 4 minutes and 15 seconds, which is around 1/125,000th of a year. The space between the layers was one meter long. And the fastest snake in the world is also one of the deadliest. The Black Mamba (Dendroaspis polylepis) can move at speeds of up to 12.5 miles per hour (5.5 meters per second). If this goes on, the Black Mamba will enter the castle compound and its bite can kill a human being in less than 30 minutes! My rice balls!'

She finished around hundreds of snakes but they kept coming. She sweated while shoving them while growing her barrier. In the meantime, she widened the first layer of the castle and removed the second layer. She narrowed down the first layer close to the castle. At this rate, the plants in between the first and second barriers would stay alive since she let the carbon dioxide go through the space. However, if there was an animal or bird, they wouldn't survive. But the space was only 1,200 meters wide and the Back Mamba could move 5.5 meters per second and they could live without oxygen for 4 minutes and 15 minutes (255 seconds). That meant, in 255 seconds they would move 1,402.5 meters. The space between the barrier wasn't enough to stop the Back Mamba. They could still enter through the first barrier if they used the same force to enter the second barrier.

The atmosphere was getting colder in each second. The sky was getting darker as the dark clouds covered the sun. Mu Lan could hear loud thunders. She knew that thunder and lightning storm had started. She couldn't see the sky because the snakes were all over her barrier. Those hiss hiss sound of the snakes making her bones go numb. It was much scarier experiencing the situation than hearing or reading stories. It was more nerve-wracking than a movie.

Suddenly Mu Lan had an idea. She contacted Carlo through telepathy, "Carl, do you hear me?"

Carlo anxiously answered, "I can. What's going on? We can't see you. There are too many snakes to see you."

"I'm going to use my power to close all the windows and doors now. Move away from the window." Mu Lan said.

Carlo screamed, "What? Why? We can't just stay here inside and let you do all the work. What about you? Why don't you come inside? It's too dangerous there-"

He was cut off by Mu Lan when she used the wind to close the doors and windows. Since it was a castle, the windows and doors were heavier. This castle could be used as a fort to protect those who were inside from the enemies who were outside.

All of a sudden, she found the flaw in her plan. The plants were inhaling carbon dioxide and exhaling the oxygen. The snakes could still live. She saw hundreds of them dying to let five to six snakes enter the second barrier. The whole island looked bloody. She closed her eyes and gritted her teeth. She couldn't help but curse Mrs. Li. 'That witch! Does she want to eliminate the snake clan from the world?' Her blue veins popped up.

She took a deep breath and controlled her anger. She contacted Carlo through telepathy again. "Carl, can you tell Antonio to control the ocean. I don't think I can hold it any longer. There are too many snakes to handle. Not only that, these snakes are too stubborn to back down. They will reach you soon."

Carlo already started sweating. He already moved away from the living room long ago. He didn't want to make Mu Liang and the four kids get scared. He was in the corridor, going to the basement. He said, "I will contact him right away." He asked Antonio, "Can you help her by controlling the water?"

Antonio was in the submarine base. He said, "I cannot do that. There are lots of snakes. I can see vipers. Thanks to the little baby's barrier, they cannot enter the castle. I'll stay here and watch these devils."

Mu Lan heard their conversation and asked, "What about the water lines? I can't stop the skinny snakes."

"I already closed the main water line long ago. Not a single snake can enter inside the castle." Pedro also joined them.
