Approaching the fortress, Yang Yi felt the faint fluctuation of Origin Energy.

After coming to this area, Yang Yi never felt the fluctuation of the original energy. Since no Primordial Converter is used, it is impossible to determine how much Primordial Energy is in this area. After discovering the fortress, Yang Yi thought that maybe the original energy in this area had already been consumed. Although theoretically, the original energy will not disappear, any form of energy will eventually be converted into original energy, and as long as there are appropriate tools and methods, the original energy can be converted into other forms of energy, but in a confined space, the original energy will eventually be converted into some unknown energy, that is, disappear. In addition, no Primal Energy Converter can operate well for a long time without Primal Energy, not even a Hallow, so Primal Converters will constantly consume Primal Energy to speed up the process.

Obviously, the fluctuations in the Origin Energy inside the fortress are by no means a natural phenomenon.

Thinking of the previous incident, that is, Arlington relied on the escape pod to enter a state of hibernation, and relied on the extra origin energy obtained by the "Energy Black Domain" to survive for 100,000 years, Yang Yi had to believe that the original energy fluctuations in the fortress must be directly related to a powerful, perhaps the War Emperor.

If Arlington can find a way to survive for 100,000 years, then the War Emperor, who is much stronger than him, will definitely be able to do it too.

Thinking of this, Yang Yi stopped outside the fortress.

"What's wrong?" Lin Feng asked in a low voice. Like Yang Yi, after coming here, Lin Feng had a very strange feeling and was always cautious. Now, Yang Yi was so nervous, even if he didn't say much, Lin Feng immediately raised his vigilance.

Yang Yi shook his head slightly, beckoning Shen Chengwen and Yujiao over.

Although there are no anomalies in the fortress other than the original energy fluctuations, and there are no dangers. But Yang Yi didn't take it lightly, so he didn't blindly take everyone into the fortress.

"Go in?" Shen Chengwen couldn't pay attention to it. Although his ability to perceive the Origin was not as good as Yang Yi's, he also sensed the fluctuations of the Origin Energy inside the fortress.

"This should be the place." Yang Yi glanced at everyone before saying, "The key to leaving here should be in an overlapping space, as long as I get close enough, I can find this overlapping space." And go in and find the key. It's just that this fortress is certainly not simple. ”

"So what to do?" Yujiao was obviously a little anxious.

"You can't go in, can you?" Lin Feng also asked.

"Now that we're here, we have to go in whatever it's inside, we just don't need to go on an adventure together."

"No way!" Lin Feng immediately understood what Yang Yi meant, and immediately objected.

"What's not to do? Hear me finish. Yang Yi glanced at Lin Feng and said, "It won't be long before Jackson and the 'Tianjiao' will arrive, even if there is no accident." We don't have to go back the way we came, we'll leave here later, so someone has to stay and answer us. ”

Lin Feng gritted his teeth, looked at Shen Chengwen, and then turned his gaze to Yujiao.

"I've handed over the 'Tianjiao' to you, and you're in complete control, don't try to keep me outside."

Yang Yi pressed his hand and said, "Secondly." We don't know what's in there, and we don't know what to expect. I don't know how long it will take to find the key to get out of here, so the people who stay behind will have to answer not only Jackson and them, but also me if necessary. ”

"Anyway, I'm not going to stay outside." Yujiao said again.

Yang Yi sighed secretly and looked at Lin Feng and Shen Chengwen.

"Okay, I'll stay outside." Shen Cheng pursed his lips when he heard this. Although I am reluctant, I can't deal with two women.

Yang Yi nodded slightly and looked at Lin Feng.

"Anyway, I'll wait for you to come out." Lin Feng didn't believe Yang Yi, nor was he worried about what would happen to Yang Yi if he stayed alone with Yujiao. Instead, he was worried that Yang Yi would be in danger. It's just that Lin Feng also knows that if Yang Yi encounters danger inside the fortress, she may not be able to help even if she follows up, and it is better to stay outside, at least when Yang Yi escapes.

Nodding at Lin Feng, indicating that he understood what Lin Feng meant, Yang Yi looked at Yujiao again.

"Don't look at me, I started talking, I ......"

"You stay outside, too."

As soon as Yang Yi said this, Yujiao became anxious.

"Don't mess around!" Without waiting for Yu Jiao to speak, Yang Yi said again, "After leaving here, we still have to rely on the Yu family's eyeliner in various places, and we can't get there safely by relying on a few of us, so you must not have the slightest mistake, and you can't go in with me to take risks." ”

"But ......"

"Nothing." Yang Yi sighed secretly, and said, "If I can find the key over there, I can also find the key here." Judging from the situation over there, the key is hidden in an overlapping space. The strongest beings of the Galactic Alliance didn't find overlapping space, so maybe the War Emperor here didn't find overlapping space either. As long as I find overlapping space, I can hide in even if I encounter danger. What if you follow me in and encounter danger, let me be distracted and take care of you, or leave you behind? Yujiao, it's not that I look down on you, it's that I can't do it with two things. You just stay outside and wait for me to come out, and then we will leave this hellish place together. ”

Yujiao originally wanted to say something, but finally held back.

Yang Yi said it very clearly, even if it was more tactful, Yujiao could hear it, she was a drag.

Shaking his head with a wry smile, Yang Yi didn't pay any attention to Yujiao anymore, and said to Shen Chengwen: "Old Shen, wait and gather all the officers and soldiers of the squadron." If something happens, get out of here and go to Jackson on the other side of the passage, and don't take any chances. ”

Shen Chengwen nodded slightly, indicating that he understood what Yang Yi meant, and then retreated.

"Don't talk about it." Seeing Yang Yi looking at him, Lin Feng sighed secretly and said, "I have a sense of proportion, and I know what to do." No matter what happens, I'll wait for you to come out. Of course, I am confident that you will return to me safely as you have always been. ”

Yang Yi smiled reluctantly, as soon as Lin Feng said this, he really didn't know what to say.

"Go ahead, don't waste time."

"I'll be back, definitely, and then we'll get out of here."

Lin Feng nodded, didn't talk to Yang Yi anymore, and turned around to find Shen Chengwen.

Yang Yi didn't delay any longer, of course he knew Lin Feng's thoughts, and he also knew that as long as he was still here, even if he found a way to leave this confined space, Lin Feng would not leave him. It's just that Yang Yi didn't feel sad, because he knew that the key had to be found.

Ready, Yang Yi flew towards the fortress.

The fortress was huge, but it was not airtight, and there were gaps everywhere.

It didn't take much effort for Yang Yi to find a passage into the interior of the fortress.

After entering the fortress, Yang Yi called Xiao Budian out. Although Yang Yi's ability to perceive the original energy is very strong, it is still a little worse than Xiao Budian. You know, Xiao Budian relies on the instinct of predator, and the blue-blooded wolf is born with a keen instinct for the original energy.

Obviously, looking for an overlapping space in this bizarrely large fortress, Yang Yi alone is not enough, and the ability of the small one can come in handy.

As Yang Yi expected, the fortress was composed of hundreds of warships, large and small. It's just that Yang Yi didn't expect that these warships only constituted the outermost layer of the fortress, that is, forming a hollow shell, and inside the fortress was another world.

A huge space with many stone pillars that resemble mountain peaks.

Thinking about it carefully, Yang Yi felt that there was nothing strange.

This fortress was too big for all the warships that had been imprisoned here to gather together, and it would not be able to form a solid fortress. Besides, this is the fortress of the Emperor of War, and there must be a space specially prepared for the Emperor of War inside, not one that is crammed to the brim.

As for the Warlords, Warlords, and Silicon Warriors who came here with the Warlord, they all obviously lived outside, that is, in the shell made of warships.

"Little one, do you feel it?"

"Wow!"

Hearing the barking of the dog, Yang Yi was slightly stunned, and reached out to pat Xiao Budian's head. "Say you're a dog, but you really think of yourself as a dog? You are the blue-blooded wolf, the royal family of silicon beasts, the most powerful silicon beast. ”

"Woo ......"

"You ......"

Yang Yi was a little speechless, and when he raised his hand, Xiao Budian ran away.

Since the change in his body, Xiao Budian is smarter than before and can understand what Yang Yi said. If one day, Xiao Budian suddenly spoke, Yang Yi would not be surprised. You must know that the intelligence of adult blue-blooded wolves is very high, even ordinary silicon-based intelligent creatures cannot be compared with them, but the growth cycle of blue-blooded wolves is too long, and very few can reach adulthood, so blue-blooded wolves have not been able to evolve into intelligent civilizations.

Yang Yi didn't chase after Xiao Budian, but looked up at the mountain peak in front of him.

This fortress is equivalent to an asteroid, and the space inside the fortress is also very huge, at least tens of kilometers, and those crisscrossing stalagmites are as short as a few kilometers, and the long ones lead from one end to the other. It's just that none of this makes Yang Yi feel strange.

Here, there is gravity, and it is outward-facing gravity.

Even if the mass of the fortress is huge enough to generate gravity, it should be inward-facing gravity, i.e., pointing towards the center of the fortress, not outward.

Obviously, this phenomenon that violates the fundamental theorems of physics does not arise naturally.

After staring at the "peak" in front of him for a while, Yang Yi walked over.

In this inner space, there is not only an outward gravity, but also a bright light source, just at the center point, emitting a light as dazzling as sunlight. Although he could use the ability of the soldiers to fly over, Yang Yi did not consume a lot of original energy.

It was just a light source, and Yang Yi couldn't see its internal structure clearly when he stood on the ground.

Climbing a mountain several kilometers high is not a difficult task for Yang Yi. (To be continued......)
