After carefully observing for a while, Yang Yi handed the telescope to Shen Chengwen next to him. When Shen Cheng heard it clearly, Yang Yi quietly retreated.

The two of them lay in ambush in a depression outside the plain, and not far in front of them was the crater on the outskirts of the plain. On the highest peak, with dazzling lights, a group of officers and soldiers of the Lei Ling clan were in full swing, and the defense formula based on the mountain was beginning to take shape.

Soon, Shen Chengwen also retreated to the bottom of the depression.

Although the depression is not very deep, it is large enough to hold hundreds of people, and it is large enough to block the enemy's view.

Inside the depression, there were dozens of officers and soldiers of the special investigation team. They are the elite of the special investigation team, all of them are human warriors, and they all have two origin energy converters, but only one is an S-level origin energy converter, that is, the one sent by Yang Yi, and their strength is a little worse than Shen Chengwen. It's just that they all have rich experience in actual combat, and they are determined, and they are definitely no worse than the enemy's officers when they really want to fight.

As before, Yang Yi and the others did not use the Origin Energy Converter, and they were all wearing protective suits. In order not to be detected by the enemy, they also reduced the power of the protective suit to a minimum, that is, only maintained the temperature and provided oxygen, and all other functions were turned off, because electromagnetic radiation could also be detected by the enemy.

When Shen Chengwen retreated, Yang Yi had already gathered the officers and soldiers.

The situation is clear at a glance, within ten kilometers of the vicinity, there is only this one under construction, and the enemy's construction progress is amazingly fast. Yang Yi and the others arrived four hours ago, when the foundation had only been laid. Although they had long heard that the engineering force of the Lei Ling Clan Legion was very powerful, most of the construction work had been completed in just a few hours, and Yang Yi and the others were still extremely shocked.

Obviously, it's not just here.

Before they came over, Yang Yi and they knew. After the Lei Ling Legion entered the Weeping Plains, they first built a tall tower in the center of the plain, which was the legion's command tower, and then began to build fortifications on the crater on the outskirts of the plain. According to Yang Yi and the others' understanding, this is the standard procedure for the Lei Ling Clan Legion to build a fortress-level military camp. As expected, there are fortifications every ten kilometers or so on the crater. Even if there are only three corps of engineering troops. At the current pace of construction, the defense line can be built in about 10 days. With the fortifications to rely on, and the heavy weapons sent by the ship, the three Thunderling Clan legions were able to hold the barracks. At that time, not to mention that Yang Yi only has twenty legions in his hands, and he has no heavy weapons to attack the fortification, even if he has more troops, he may not be able to take down this fortress. To put it bluntly, just let the legions of the Lei Ling clan establish a defensive line. Even the Silicon Charm army commanded by the War Emperor could only sigh with admiration.

It's definitely not an option.

Of course, Yang Yi and the others came here not only to observe the enemy's situation, but also to look for opportunities.

"Obviously, the Lei Ling Clan Legion is preparing to stay here for a long time, and judging from the way the outer defense line is laid out, the enemy intends to control the entire Weeping Plains." Yang Yi drew a circle on the ground. "The area of the plain is huge. Enough to garrison hundreds of legions, even if it is conservatively estimated. Accommodating a hundred legions is no problem. From this, it can be concluded that the enemy did not just settle here temporarily, but must have made long-term plans. ”

"Also, judging by the speed of construction of the outer defensive line, I am afraid that the enemy's large forces will arrive soon, no later than ten days at the latest." Shen Chengwen added.

Yang Yi nodded slightly. "When the enemy's large forces arrive, we can't do anything without even a hundred legions," he said. In other words, if you want to fight, it's just a matter of a few days. It can't be delayed any longer. It's just that how to fight, we have to figure it out. ”

"What else is there to say about that?" Shen Cheng looked at Yang Yi incomprehensibly.

Yang Yi smiled faintly and didn't say anything.

"Since we have come here, the enemy's large forces have not arrived, and the enemy does not know that we are here, and the precautions are very lax. If nothing else, we have been here for four hours, and we have not found any enemy patrols, even the troops that had been on guard near the fortifications have withdrawn. Shen Chengwen paused slightly, and then said, "Destroy that fortification, and the enemy's alert troops will rush over." Even if you can't beat it, you can only retreat, and you can force the enemy to strengthen your defenses, which will naturally slow down the construction of fortifications. As expected, the enemy's large forces would not arrive until the camp was fully established. Of course, it will definitely be no problem to take out a few engineers with our strength. ”

"And then?"

"And then what?" Shen Cheng looked at Yang Yi incomprehensibly.

"Do you think that after being attacked, the commander of the Thunderling Legion will think that the Silicon Phantom Alliance did it?

"This ......"

"That's right, the Silicon Charm Army is near here, and the commander of the Lei Ling Clan Legion may not know the truth, but as long as the battle report is sent back, the Wanluo War Emperor will know that it is not Kutum's Silicon Charm Legion that is attacking the Lei Ling Clan Legion here, but us, the Legion of the Human Federation." Yang Yi let out a long breath and said, "If Emperor Wanluo is ruthless and concludes that it is us, he will immediately withdraw the three legions and then destroy the Slag Star." When the time comes, even if we are lucky enough to escape, we will definitely not be able to stop the Thunder Clan's fleet from leaving. What's more, if the Wanluo War Emperor were a little smarter, he would block the Slag Star and use us to threaten the Star Soul Empress. Don't forget, the Star Soul Empress formed an alliance with the Human Federation through me. When the time comes, the Star Soul Empress will inevitably compromise with the Wanluo War Emperor. Even if the Wanluo War Emperor is not smart enough, or for some other reason, such as not knowing that it is us who is hiding on the Slag Star, he will let the large army arrive on time. We can't even defeat three Thunderling legions, so why should we fight hundreds of legions? ”

"Do you mean we don't do anything?"

"Of course not, if you don't do it now, you're waiting for death."

"So what to do?"

Yang Yi let out a long breath and said, "Actually, your idea is not wrong. The priority was to try to slow down the construction of the enemy's camps. To put it bluntly, as long as this camp is completed, even if the large army of the Lei Ling Clan does not arrive, those three legions can make us pay a heavy price. It's just that we can't attack directly. The battle begins, and regardless of the outcome, we will be discovered by the enemy. ”

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

"We arrived at the right time, and the enemy was lax." Yang Yi glanced at the officers and soldiers around him. "It's not too late, let's do it now."

"How?"

"What is this place?"

Shen Chengwen was slightly stunned, not quite understanding what Yang Yi meant.

"This is Slag, and we've figured out the inner workings of this planet. If there is an earthquake and it happens to be near the Weeping Plains, even if it is a coincidence, the enemy may not be suspicious. You know, this planet has long been hollowed out, and the geological structure is very unstable. Yang Yi smiled faintly and said, "As long as the intensity of the earthquake is high enough, it is not just a fortification that will be damaged." ”

At this moment, Shen Cheng understood when he heard it, and the other officers and soldiers also understood.

Yang Yi didn't ramble anymore and stood up first.

It's just that before Shen Cheng could get up, Yang Yi pressed his hand.

"What's wrong?"

"The others stay here, let's go up and have a look."

Shen Cheng was stunned for a moment, but then thought that Yang Yi was extremely sensitive to original energy fluctuations, and he must have discovered something, so he followed.

Soon, the two returned to the location where they had been lurking.

On the mountain peaks in the distance, the lights are still bright, and there are still many engineering officers and soldiers of the Lei Ling clan who are busy, but they are not the same as before.

After carefully observing for a while, Yang Yi let out a sigh.

"What did you find?"

"There is an officer here, the original energy fluctuation is extremely obvious, and the other engineering officers and soldiers have been organized, it should be an officer of the engineering unit."

"How high-ranking officer?"

"That guy has an advanced Primal Converter, at least AAA-class, maybe S-class." Yang Yi looked at Shen Chengwen, "With an Origin Energy Converter of this level, it should at least be a mid-level officer, right?" ”

Shen Chengwen nodded and said, "If it's a mid-level officer, then this guy must be a veteran, maybe he has been in the Lei Ling Clan Legion for hundreds of years, and he may even have participated in the last Greenwich War." Otherwise, the most you have is a Class A Origin Converter. ”

"Are you sure?"

"At least in the last war, the Lei Ling Clan didn't have enough S-class Origin Energy Converters, and they were only distributed to generals, and it was difficult for mid-level officers to obtain."

"Perhaps, that guy is the commander of the engineering troops."

"It's possible." Shen Chengwen paused slightly, and then said, "There are only three legions here, and we have not found any heavy engineering equipment, so it is very likely that these engineers are the engineering troops of the legion." In this case, their commander would definitely be a mid-ranking officer. ”

"In other words, he is in charge of the construction of the entire camp?"

"If he's the commander, he's definitely in charge."

"So, does he know why he built this camp?"

"This ......" Shen Chengwen hesitated a little before he said, "It shouldn't be clear, he is only responsible for the construction of the project, so he only needs to know what kind of camp to build, and what is the purpose of building the camp, obviously it has nothing to do with him, and the commander above will not tell him." ”

"At least he knows the specifics of this camp."

Shen Chengwen nodded and said, "Not only does he know, but only he knows." To put it simply, he knew better than anyone else in the Legion how big the camp was once it was built, and how the various facilities were deployed. If you want to figure out the layout of this camp, you have to capture him alive. ”

"Looks like we're going to have to plan it well."

"Capture him alive?" Shen Cheng was stunned for a moment, and looked at Yang Yi in disbelief.

"He only has an S-class Origin Energy Converter at most, and he is an engineer, and his combat power is not too strong, you won't have confidence in yourself, right?"

Shen Chengwen rolled his eyes, and was speechless at Yang Yi's words.

It's not that he doesn't have confidence in himself, but it's not easy to capture alive a Lei Ling clan officer with an S-class Origin Energy Converter, even if it's just an officer of the engineering army. (To be continued.) )
