"Brother Feng, since you said you could not kill this tree, my strength was far inferior to you. In this way, I would have no way to kill this tree. Then, we were trapped like this." Wang Gongnan said to Brother Feng with a confused look.

"Master, you are not as smart as me. You are more wise. You must be able to come up with a way to deal with this demon tree." Hearing Wang Gongnan's words, Brother Feng immediately said.

"So good, please help me analyze it. In addition to the earth fire that can cause damage to this tree, what other means do I have to deal with this tree?" Wang Gongnan asked Brother Feng.

"Honor, to be honest, many magic weapons cannot be used in this tree body. For example, the two spaces in your hand cannot be smashed out. So I think you really have no other way to deal with this tree except for earth fire." Brother Feng knew that he was discussing ways to deal with this tree at this time. He had to tell the truth and say whatever he thought of, so he said to Wang Gongnan bluntly.

"Very good, then now we can be sure that with a single method, we can't deal with this tree. So if several methods are superimposed, will there be a way?" Wang Gongnan said.

"Several ways to superimpose? If it were me, I could peck with my mouth, scratch with my feet, and burn with fire. If this was outside, it would really bring harm to this demon tree. But now we are trapped in the heart of this tree, and the fire is burning without air to help burn, then I can only be like a little borer, just like a flea on Lao Tie's body, which can't bring any pain to it, let alone hurt it." Brother Feng said.

"If I were outside, what I could cause damage to this tree is to use two spaces to smash and earth fire. Of course, my current Qingfeng sword can also cut off some wooden blocks, but the tree is so huge, it would be useless to use the Qingfeng sword." Wang Gongnan said.

"Then, the head of the family said that he wanted to use the superposition method to deal with this tree, but he still couldn't find a way. Alas, fire was originally the nemesis of wood. Now we both have fire, but we can't do it with this tree. I'm really cowardly." After much discussion, it seemed that we were still returning to the topic at the beginning. Brother Feng said disappointedly.

"Haha, Brother Feng, don't be discouraged. After discussing with you, I feel more and more a little surprised." However, Wang Gongnan said with a smile.

"Ha! Master of the family, you are really amazing. Please tell me what is the solution? Is it useful?" Brother Feng asked immediately excitedly.

"Haha, of course you have to work hard. Aren't we discussing the superposition method just now? I'm going to use my earth fire to burn this tree with the fire you sprayed. Because fire is the nemesis of wood, dry fire, how can there be no reason to burn it out?" Wang Gongnan said with a smile.

"But, didn't the head of the family say before that there is no air here, so the fire cannot burn this tree? Ah! I'm so stupid, ha! I thought that the head of the family has a red and purple-clothed world, and there is air inside. As long as the air inside is drawn out, the fire here can burn!" After hearing Wang Gongnan's words, Brother Feng said with a puzzled expression at first, but suddenly he was shocked and shouted happily.

"Okay, your method is really good. Just as you said, I will lead out the air in the red and purple world." Wang Gongnan nodded and said.

"Head of the family, you obviously came up with this method, but why did I come up with it?" Brother Feng asked in confusion.

"Haha, Brother Feng, don't worry about these things. You said it just now, that's what you thought of. There is still a difficulty now. We have to make a space here first before setting the fire. How about it? Do you have the confidence to make a space here?" Wang Gongnan said with a smile.

"Master, this is easy. Please let me go. I will peck my mouth and grab my feet. I will soon create a space." Brother Feng said.

"Okay, big!" The palace nodded and shouted, causing the dog-qi killing cage to grow rapidly. When the dog-qi killing cage was moved in one direction by inexplicable force, the palace-nan issued an order to the dog-qi killing cage to stop moving, but it did not follow the palace-nan's instructions. This time, it accepted the palace-nan's instructions.

"Kaku..." Immediately, the dog-fury cage made a sound, and then the fence on the cage became larger and longer, and the gap between the fences also widened.

However, in the gap between the fences, something wooden squeezed in.

"Ga, I'll peck!" Brother Feng immediately let out a strange cry, pecking at the wooden thing in the gap in a fence.

"Crack..." Immediately, it tore off a wooden strip two meters long and one foot wide and thick from here.

"Ga, head of the family, the position is too narrow and it is hard to use force, so I can only pull off so much at once." Looking at the torn wooden strips, Brother Feng said to Wang Gongnan very embarrassedly.

"You can pull so much off in one go, all depends on your mouth strength, and you control the force and don't hurt my cage. You are doing a good job. OK, keep going." Wang Gongnan praised Brother Feng.

"Okay, ga!" Hearing Wang Gongnan's praise, Brother Feng felt a little relieved, and immediately responded, pecked at the gaps between the fences, and pulled off a piece of wooden strip of the same size as before.

"Ga!" It screamed again, and pecked at the place where the wooden strips were torn off by itself, but the wooden strips torn off this time were actually smaller than the two before, and Brother Feng couldn't help but be stunned.

"Brother Feng, don't be alone. It's not that you don't have enough strength, it's that there is not enough space there. The power you use cannot achieve the expected effect. Don't stop, look, once you stop, the wood there is growing by itself." Wang Gongnan said immediately.

"Okay, I'll peck!" After hearing Wang Gongnan's words, Brother Feng stopped hesitating and pecked "dongdongdongdongdong". For a while, long wooden strips kept rushing into the dog-fury cage, and even the bed was filled with wood.

"Catch it!" Wang Gongnan immediately had an idea and collected all the wooden strips and wooden Xiao that Brother Feng pecked out into the red and purple-clothed world.

"Master, let me go out. Now my neck is no longer reachable." After a while, Brother Feng said to Wang Gongnan.

"Okay, let go of your spiritual consciousness at any time. Once something is wrong, I will take you back into the cage." Wang Gongnan replied, and then a thought arose, Brother Feng came out of the cage, his body was in a small space pecked out by it. It shrank its body, and it was just enough for it to be stunned.

"Ga, I'll peck!" When my body came here, Brother Feng immediately shouted, pecked at the wood in front of him, and tore off a long strip.

"Cover!" Seeing Brother Feng tearing off a long piece of wood, Wang Gongnan immediately had an idea, put the wood into a cage, and then received it into the red and purple world.

"Dongdongdongdongdong..." With a sound, wooden strips drilled into the dog-fuelled cage, and Brother Feng slowly stood up straight.

"Ga, very good, I've used my mouth and feet now!" After a while, Brother Feng said excitedly, then spread his wings slightly, pecked forward, and grabbed his feet under him. Suddenly, the wood chips here were flying, making it too late for Wang Gongnan to collect them.

However, as long as the royal palace sends an order, the dog-qi killing cage can be collected by himself, so now the wooden strips that Brother Feng has torn off can enter the dog-qi killing cage very smoothly. When the wooden strips reach the dog-qi killing cage, they will automatically pile up, which makes it convenient for the royal palace to collect.

In this way, not long after, Brother Feng dug out a tree hole space several meters in square meters here.

"Brother Feng, enough, ready to set fire." Wang Gongnan said to Brother Feng.

"Okay, after digging such a big hole, the tree has no reaction at all. It's really a dead tree." Brother Feng retreated to the dog-your-killing cage and said.

"Haha, it's not that it doesn't feel it, but that Lao Hong and Lao Tie must be attacking it crazy at this time. Compared to the large number of branches and leaves falling and the roots being broken in pieces, it is so huge. What are the injuries you cause to it?" Wang Gongnan said with a smile.

"Oh, too, hey, I'm narcissistic again." Brother Feng said embarrassedly.

"Okay, Brother Feng, you set the fire. I will take out space from the red and purple world now." Wang Gongnan said.

"Okay, I'll squirt!" Brother Feng responded and immediately sprayed forward with a sip of fire.

"Coax!" The fire spurted forward, and immediately blew out a stream of wind from the gap of the dog-fury cage. Following the fire spurted out by Brother Feng, the fire was blown forward and immediately hit the tree wall in front and started to burn.

"Boom..." Immediately, the sound of firewood burning sounded here.

"Brother Feng, come in, fire!" Wang Gongnan immediately let Brother Feng enter the dog-qi killing cage, and he also released the earth fire.

The two fires burned from both sides separately. When the two fires burned to the wood, the wood did not catch fire immediately. Instead, the two fires were too strong and the temperature was too high, so the wood in the place where the fire was roasted immediately turned into black coke. Then, under the contact of the wind blowing out of the dog-qi killing cage, the black coke immediately braised.

Only then did Brother Feng understand why using fire to burn things requires air.

If there is no air here burning with fire, the wood here will soon be charred by high temperature, and then it will become a hard charred wall, which will not expand at all in front of you. Instead, it will be very troublesome to expand again.

When firewood is burned, of course there is smoke and waste gas. Wang Gongnan draws air from the red and purple world to the dog energy killing cage, and then lets the cage blow the air to the fire, and the exhaust gas generated by the combustion quickly pounces on the dog energy killing cage.

Wang Gongnan could not let the waste gas enter the cage. He knew that the waste gas contained a lot of carbon monoxide, which was very poisonous and killed people faster than corpse poison.

"Out!" Immediately, it put the space in its left hand out of the dog energy killing cage and opened the exit of the space. In this way, the waste gas and ashes generated will automatically pour into the space.
