The secret passage was already full of all kinds of traps, but because Zhao Yuan hadn't come in yet, it hadn't been activated.

The secret passage is not large, and can only accommodate one person with a cat on his waist. In such a situation, it is impossible to dodge the trap, so you can only resist it. Although the secret passage is not long, the number of traps hidden is extremely large, and those who believe in ant thieves will suffer heavy losses even if they are strong when they come here!

Zhao Yuan quickly caught up with Ying Ji, Bone Girl and the others, and they were getting together to discuss something. Zhao Yuan took a flashlight and shone it, and when he saw that there was still a road ahead, he asked, "What are you doing here, why don't you continue to walk inside?"

"I can't go. Ying Ji turned around and said, "The road ahead is blocked by an invisible energy, and we can't get through, we are trying to find a way." ”

"Oh?" Zhao Yuan remembered Li Chenghao's story at the beginning, knowing that this invisible door was most likely the door to the secret realm of immortals, he couldn't help but feel a burst of excitement in his heart, and hurriedly asked: "Can't you break through?"

Ying Ji shook her head and said, "Bai Mei and Li Chenghao tried just now, but they couldn't get through." This invisible energy is both powerful and weird, and will return all the power of the collision. If it weren't for Bai Mei and Li Chenghao, they would have to be injured!"

"That's it......" Zhao Yuan frowned slightly, and quickly thought of a way.

Hao Li said: "Just now Li Chenghao told us that the last time he was here, he also encountered this invisible energy gate, and he hit it several times, but he couldn't rush in. In the end, it was an earthquake that made this energy gate disappear......"

Cheng Haoyu took over the conversation and said, "Do we also have to simulate an earthquake to make this energy gate disappear?"

Ying Ji agreed: "This is also a solution. ”

"No, it won't. Zhao Yuan objected and said, "It's not that simple. At the beginning, the energy gate disappeared, mostly because the earthquake affected the dragon veins of Changbai Mountain, causing the earth qi to leak out, and the energy gate collapsed! With our strength, it is not difficult to simulate an earthquake, but the difficult thing is to let this earthquake affect the dragon veins of Changbai Mountain, so that the earth qi leaks out, and it just impacts the energy gate...... Maybe there is no in the energy gate, but the location of the entrance to the secret realm is exposed, so that the people of the ant thieves can find this place in advance!"

After pondering carefully, Hao Li said, "What Brother Zhao said makes sense, how can the entrance of the Immortal Secret Realm be opened by an earthquake?" There must be other reasons!"

After thinking about it for a while, Ying Ji and Cheng Haoyu also agreed with Zhao Yuan's statement.

After sighing, Ying Ji said, "Then what now? If this energy gate doesn't disappear, we won't be able to enter." ”

Cheng Haoyu put forward a suggestion: "Why don't we go outside and find a place to hide, and when the ant thieves arrive, follow them behind and follow them in? ”

Zhao Yuan's eyes lit up. Cheng Haoyu's words reminded him of the bottle of blood he had seized from the ant thief in Rongcheng a few days ago. According to the ant thief's confession at the time, this bottle of blood was the 'key' he made on the order of the queen ant. Could it be that it is used to open this invisible door?

Zhao Yuan hurriedly said: "You guys turn sideways, let me move to the front, maybe I can have a way to open this invisible energy door." ”

As soon as everyone heard this, they immediately complied, turned sideways one after another, and tried their best to stick their bodies against the rock wall of the secret passage, so that Zhao Yuan could squeeze through.

After a lot of tossing, Zhao Yuan finally squeezed to the front of the team, and as soon as he stretched out his hand, he felt something blocking the front, although he couldn't see Qi or see it with the naked eye, but it really existed. Once forced, it will bounce back, and the more force it uses, the stronger the force will bounce back. In such a situation, it is definitely not possible to break through, and you can only get yourself injured.

Zhao Yuan didn't rush to immediately use his heart and blood, but first asked the puppeteer to scan it and find a way to 'open the door'.

Soon, a large text appeared in front of his eyes.

According to the advice given by the puppeteer, if you want to 'open the door', you must either be strong enough to break this invisible energy gate, or use a variety of materials to make a spirit rune, and then draw different runes according to different secret realms, so as to master this invisible energy gate and be able to open and close it freely. In addition, there is another method, which is to use the evil method to corrode the energy gate, but the puppeteer did not list the specific method, but just said, 'This method is too ruthless and hurts the heavens and harmony, so it is not recommended to use it, let alone introduce it.'" ’

"It seems that the blood collected by the ant thieves should be this third method. Zhao Yuan muttered in his heart.

He couldn't use the first method because he didn't have enough strength. Although the second method can be used, there are not so many materials in hand now, and the ant thief's people have also arrived nearby, and they will soon touch here, so it is impossible for them to run back and gather enough materials to come over.

The only way that works is the third way. And in his hands, there is exactly the blood of the captured heart!

This thing is an evil thing made by the ant thief, and it would undoubtedly be quite good if it could be used to yin the ant thief! I believe that those who have been killed by the ant thief because of the blood of the soul are also happy to see such a thing.

It's a pity that the puppeteer didn't give a specific introduction to the third method, so how to use the blood of his heart and soul has to be explored by Zhao Yuan himself. Immediately, he opened the ring and took out the blood from his heart.

"Since it's the key, it must be used directly on the energy gate...... It doesn't matter, try it first, if it doesn't work, it will definitely bounce back by the energy gate, I just need to catch it with the bottle in time and don't let it spill. ”

After Zhao Yuan made up his mind, he uncorked the bottle and waved his hand to splash the blood in his heart towards the invisible energy gate in front of him.

The blood in the heart fell on the invisible energy gate, and it did not rebound back, but spread rapidly, and in the blink of an eye, there was originally only a drop of blood in the heart, and it spread into a large piece, covering the entire energy gate. At the same time, there was a harsh "snort" sound, as if strong acid was corroding things, and it also emitted a pungent stench.

"The blood in my heart is corroding the energy gate, it seems that I am lucky, I really made it work!" Zhao Yuan immediately judged the situation, and under the great joy, he hurriedly turned his head and ordered Ying Ji and the others: "Activate the trap in the secret passage, and when the energy gate is completely corroded, we can enter." ”
