Mill Institute, underground man-made portal.

This time, the entire Mill Research Institute did not hold any kind of farewell ceremony like the first time, and after completing the final mission confirmation, the Hades and Gong Piqing jumped into the abyss-like portal in front of them without hesitation.

After the two jumped into it, the staff in charge of controlling the portal immediately destroyed the rune structure on the portal, and the portal that they had been debugging for a long time was completely destroyed in an instant.

And if this scene seems to outsiders, it is as if the Mill Institute prepared a trap for the Hades and the World Tree, and when they were sent to the Demon Realm, they closed the portal as soon as possible and left them in the Demon Realm forever.

But in fact, they are also forced to do so, because when the portal is opened, there will be strong energy fluctuations on both the earth and in the country of machines, and this energy fluctuation is powerful and special, and even their "abnormal energy detectors" can clearly detect it, since this is the case, then those lords and mages in the demon world can naturally detect it easily.

They opened the portal in order to send Hades and Gong Piqing away from the earth, which means that from then on, there is only a ghost left in their Mill Research Institute, and the earth has suddenly become two major lords and a hidden Xiguan Renai Research Institute as their opponents, if they leak the news that Gong Piqing and the Hades were sent to the demon world, the two lords and the Xiguan Renai Research Institute will attack them together, and the ghost will be almost impossible to deal with.

If the time progress of the Earth and the Demon Realm were the same, their safety factor should be greater, but now that Hades and Gong Piqing have both jumped into the portal, a second behind the portal may mean that the Earth World has passed an hour or more.

In other words, if it seemed to Hades and Gong Piqing that their mission went smoothly and it only took a day or less to get the Endless Energy Device, by the time they happily returned with the Endless Energy Device, they might have spent nearly a month on Earth.

According to their previous calculations, a day in the Demon Realm is really comparable to a month on Earth.

Although the mission of Hades and Gong Piqing seems to be quite difficult, it is not a survival challenge for them who remain on Earth.

If Gong Piqing and Hades spent three days in the Land of Machines to get the Endless Energy Device, and by the time they returned, three months had already passed on Earth, and their Mill Research Institute had now entered the stage of complete energy exhaustion, and even most of the electricity needed at present needed to be supplied by hand-cranked generators, it was hard to imagine how they would spend these three months or even longer in this context......

The sound of the portal closing and the sound of the surrounding machinery echoing through the huge underground space, and finally the virus was recovered into a fixed container, and all the electrical equipment stopped working in order to reduce the current power consumption as much as possible, and even took out the candles and matches that had been prepared in advance......

After everything underground was engulfed in darkness, an equally dark figure jumped in front of the old man and the commander's team, and with the help of the candle flame in the hands of the staff behind them, they saw the long knife behind the figure, which was a ghost.

"Why didn't you send them all?" The old man recognized the ghost, so he was not frightened by his assassin-like attire for a while.

The ghost smiled bitterly, "I said goodbye last night, I don't know if they saw me today, anyway, when they came out this morning, I was still sleeping." ”

The old man smiled, "Oh? How did you know you were leaving today? An early farewell? Didn't drink anything? ”

The ghost laughed, "One by one, they were already tired and dizzy, if they drank again, I am afraid that they would not be able to walk today, so it is okay, let them feel that I didn't wake up, so I left without worrying about my heart, with the strength of the two of them, they should return safely like last time." ”

"You called them peace last time?" At this moment, a commander standing behind the old man looked at the ghost in surprise and said, "Do you know what they both experienced in the Machine Nation last time, according to their mission descriptions? ”

The ghost scratched its head, "I think I heard you say it, but I forgot about it...... Maybe my brain has been broken, and my memory hasn't been very good since I came back from the country of extreme cold......

"If they hadn't deliberately exaggerated the enemy's abilities, they would have killed two lord-level monsters in the Land of Machines! Their mission files are still in the archives! The senior commander said.

The ghost snapped his fingers, "Oh, I remember! Seems like a mysterious killer and a giant, right? They were all at the lord level, and it was quite tricky to listen to what they said, but in the end, they were killed by them and returned safely. ”

At the end, the ghost laughed, "They don't seem to be the kind of people who will brag about how good their enemies are and then hint at how good they are, but if I'm not mistaken, it seems that the World Tree erupted later to save the Hades, right?" When they returned, the Immortal was unconscious, and the World Tree had a half-dragon-like mutation. ”

The three heads of departments nodded at the same time, "That's right. ”

"It seems that you are right not to let them go to that tower, they fought a total of two floors in that tower, and they encountered two lord-level bosses, and the outbreak of the world tree is almost incomprehensible, so it can basically be said that there is a lord-level boss on each floor of that tower, and I don't know how many such bosses there are in the entire country of machines."

The ghost said worriedly, "I wish I woke up one day and saw them coming back safely with the Endless Energy Device, instead of them coming back in disgrace and saying, 'Hey brothers, I've got good news and bad news, the bad news is that we didn't get the Endless Energy Device but the good news is that we blew up the Nation of Machines.......'"

His words soothed the already frozen air, and the commanders laughed one after another, and at the same time, the staff in front had basically finished the finishing work and were about to pack up and leave.

"Let's go, it's going to close soon, and hopefully...... I'll never use it again. The old man said, beckoning to the commanders and ghosts behind him.

Then the group turned around and walked towards the darkness behind them with the help of the candle's faint light source.

But it was precisely because of the dim light that none of them noticed that the inconspicuous figure had once again dived into the never-ending darkness behind them after they had left.

As the ghost listened to their footsteps fade away, he returned to the edge of the well, standing in the same position where he had stood.

Time seemed to be pulled back to the past by his behavior, at that time, the entire underground space was brightly lit, and countless headlights illuminated the portal in the middle like the stage of a concert, and the four of them stood at the edge of the four directions of the portal, they were the actors who were about to perform on stage.

Yes, at that time, nothing had happened yet, everything had not yet come, they knew that it was a murderous mission, but they still jumped in without hesitation, four super soldiers, four squads, without exception.

In fact, at that time, why was they not afraid in their hearts? It's just that under so many eyes, the fear in their hearts has been infinitely reduced, just because with so many team members behind them, their self-esteem does not allow them to be afraid.

This well is even more significant to the ghost than the other three super soldiers, because out of the four squads, only his squad, except for him, has been wiped out.

Once upon a time, the Ghost never shed a tear, not even in the Land of the Dead against the Immortal Legion's tens of millions of troops, even when alone against the elite forces of the Immortal Legion in the deadly illusion created by the dragon.

But today, he really shed tears, he didn't have wine, not even a substitute for wine to honor the warriors who had left their lives forever in the land of extreme cold.

So he had to use tears to make wine, sacrifice and farewell.

"The Demon Realm is very dangerous, no matter which country it is, you are all more capable than me...... May you have a safe journey on this trip, and I don't want to destroy the demon world, but only my brothers can ...... Triumphant return ......"

He muttered softly, slowly closing his eyes, letting the darkness engulf his emaciated figure.

"Ghosts? Phantom! You're not in there! Suddenly there was a shout from behind him, presumably because he hadn't followed him and was discovered.

"Oh! I'm here! He hurriedly shouted.

"Hurry up! It's going to be locked down soon! ”

"It's coming!" He shouted, running towards the exit at an almost teleportation speed, and what he had left behind was also the best and most tragic time of his life......
