Because since the enemy army was able to suck the five of them in at the same time without any resistance, it proved that the difference in strength between the two sides was too great, to the extent that it was incomparable. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

After realizing the huge difference in strength between the two sides, they didn't intend to make those senseless resistances, especially Shen Huo knew that he couldn't die yet, he had to be patient and wait for the opportunity to pass on the news he learned to Duan Rui through the communication jade slip.

To the surprise of the five of them, just as they were waiting for the enemy to arrive, the black vortex closed automatically, and the five of them sat in the space-time tunnel as if they had been forgotten.

Soon, Shen Huo realized that this space-time tunnel was very likely to operate autonomously, and it was very likely that it would be opened every once in a while to draw space power from the outside world and continuously improve itself with the help of the spatial stability of the spatial structure cornerstone.

After realizing this, the mood of the five people instantly relaxed a lot, and they still had the opportunity to discover more secrets of the enemy army without being discovered, they were not afraid of death, but hoped that their sacrifice could bring back enough information for the legion.

Realizing that they hadn't been exposed, the five set off again, and they had to determine what the space-time tunnel was and where it was connected at the other end.

It is impossible for the enemy army to be idle and bored to build an underground space-time tunnel to play, and seeing the other party's efforts to hide this space-time tunnel, you can know that there is definitely a big conspiracy hidden here.

The five of them sneaked and ran along the space-time tunnel for a long time, and just when they felt that they were already a little tired, a powerful inexplicable force suddenly appeared on the surface of their bodies, and then they found that their bodies were constantly moving backwards in the space-time tunnel.

The process is not fast, but it is not slow, in short, the five of them even have a sense of time and space, and when everything is over, they find that they are no longer where they used to be.

Because there weren't many references in the space-time tunnel, they couldn't figure out how far away they had been transferred, and they couldn't figure out if the time node they were at was the same moment before the previous mutation occurred.

The confused five people had no choice but to continue sneaking, and in the process they finally realized the difference, and after experiencing a black vortex to absorb external energy, the five people walked in the space tunnel, and they could clearly feel that the current space-time tunnel was more stable than before, and the feeling of walking in it was becoming more and more obvious.

Sure enough, this space tunnel is gradually drawing strength from the outside world for self-improvement, and the diameter of the space tunnel has also increased by nearly one meter compared to before, and the space power is becoming more and more perfect and stable, which is simply the rhythm of continuous evolution towards the perfect space tunnel.

"Can you roughly estimate how much time has elapsed between the tunnel change just now and the last time there was a black whirlpool?" After Duan Rui figured out the experience of Shen Huo and the five people, the previous speculation in his heart was also more verified.

The energy of the space elements contained in the outer soil layer and the energy in the cornerstone of the space structure are being regularly absorbed and assimilated by this space-time tunnel, and it is believed that it will not be long before it can evolve to the point of near-perfection, when this space-time tunnel will be able to continuously dissipate under the noses of the coalition forces and input a large number of enemy back main forces to the battlefield.

And what scared Duan Rui the most was that he didn't know where this space-time tunnel was going, and in addition to being able to teleport troops, it could also randomly teleport a few ninth-level demon beasts into the stronghold without warning.

If this is really the case, the Terran coalition will definitely have no time to react, and when the top combat power in the coalition army arrives on the battlefield, the main force of the coalition army may have already collapsed in the face of absolute strength and has been completely conquered.

What's more, this stronghold is not too far from the place where their Volunteer Legion is guarding, if the space-time tunnel is really completed, their stronghold will definitely be the first to be attacked and persecuted, which is something he absolutely cannot accept, so Duan Rui's first reaction is to destroy this space tunnel and destroy the enemy's plan.

Shen Huo and the five of them glanced at each other and shook their heads helplessly at Duan Rui, saying that the time flow in this space tunnel was fast and slow, and they couldn't figure out how long it had been since they came in, so they couldn't estimate how this operation cycle should be calculated.

"I think the energy cycle of this space tunnel is likely to be related to the speed of energy consumption it draws from the foundation of the space structure, have you noticed that this space tunnel has just absorbed energy once and is now rapidly fusing that part of the energy. ”

"And when we first came in before, there was much more energy in the space tunnel than now, that is to say, the missing part of the energy is constantly improving the space tunnel in front of us, and when this part of the energy is completely consumed, it is likely that the space tunnel will draw new energy from the outside world again. Seeing Duan Rui's pensive expression, Elder Su reminded.

Elder Su's martial arts skills are very special, not only can he reduce the sound wave and compress it into all the surrounding energy, but also can transmit it to the ears of multiple targets at the same time, so Duan Rui and his party all heard Elder Su's transmission.

"Hmm! When Elder Su said this, I think this is very likely, just now we did feel that the energy was rapidly depleting during our journey, but after absorbing it just now, the energy in the space tunnel has become abundant again. After listening to Elder Su's words, Shen Huo's eyes lit up, and he gestured to everyone.

"Well, it seems that this possibility is indeed very high, the enemy deliberately built this space tunnel under this remote stronghold, the purpose should be to prevent the high-level of the Terran coalition from discovering the existence of this space tunnel, so there must be a bigger secret hidden behind this. Duan Rui nodded and said to everyone.

The space tunnel is built underground, and the space energy absorbed is derived from the elemental energy in the soil layer and the space energy absorbed by the cornerstone of the space structure from the natural world, if these means are built on the ground, the speed of self-improvement of the space tunnel can be increased several times compared with the current one, but the enemy army deliberately seeks the near and far and builds it underground, and its ambition and purpose have to be carefully figured out.

"So we must not sit idly by, we must leave here before the end of this space-time tunnel self-improvement and send the news back to the coalition headquarters to inform the higher-ups that we must eradicate this hidden danger before the enemy reacts. Duan Rui continued to express his opinions.

Everyone nodded in agreement with Duan Rui's statement, and the action has risen from the unilateral action of the Volunteer Legion at the beginning to a mutual game between the two armies, and the demon beast army wants to trap the Terran coalition army, and they will never agree......
