At this moment, the entrance and exit of the base are already crowded with a large number of black demons, and through the pictures taken by the scouts from high altitudes, the appearance of the entrance and exit of the base cannot be seen at all.

In an instant, the low-altitude pottery wolves began to dive downward, releasing ice picks with thick arms when they were about two hundred meters away from the black demons on the ground.

The ice pick that hit the black slayer suddenly burst into a cloud of cold mist, causing the black sage to be temporarily frozen due to the attack, and a thin and transparent layer of ice condensed on its body.

At the same time, most of the Black Demons blasted a thunderstorm at the swooping Taowolf.

One after another, golden thunderstorm balls of light rose into the air, hitting the Tao Wolf who was still diving, and exploded into clusters of golden flames.

Nearly half of the thunderstorms accurately hit the potterwolf, causing the potterwolf to either be displaced by the bombardment or retreat, and those thunderstorms that did not hit the potterwolf also affected the potterwolf pack with a shockwave.

A sea of fire began to burn in the low altitude above the entrance and exit of the base, and the black demons on the ground seemed to have suffered frost, flashing from time to time with patches of cold ice emitting a pale blue light.

Chen Feng saw that they were fighting more and more fiercely through the surveillance footage displayed on the monitoring wall, and speculated about the outcome of their battle.

According to the news sent back by the scouts on the investigation of the black devil and the pottery wolf at this time, the combat power value of the black devil is slightly higher than that of the pottery wolf, although it does not use the ability to fly, but the number is much more than that of the pottery wolf, so it is inferred that it may be the pottery wolf's side that suffers.

However, half an hour has passed, and the number of black demons entering the base every minute is gradually decreasing, because the fierce battle between the black demons and the pottery wolf blocked the entrance and exit of the base, making it difficult for the black demons themselves to enter, but until now, not a single pottery wolf has entered the base.

After another half an hour, there was no more black fire at the entrance and exit of the base, and there was only a fierce battle above the entrance and exit of the base.

Chen Feng thought to himself that if they didn't fight a victory, I was afraid that no ghost would be able to enter this base again, and he didn't know if this was a good thing or a bad thing, so he chatted with Ma Yuanliang about their battle in the communication.

Ma Yuanliang in the communication said indifferently: "Let them fight, it is best for them to lose both."

Chen Feng analyzed while observing the picture in the monitoring window: "This is unlikely."

"How?"

"They've been fighting for so long, and few ghosts have died, and they don't seem to use all their strength."

"Didn't use all your strength?"

"Yes."

Ma Yuanliang in the communication video looked down at the surveillance there, and saw the fierce attacks between Heisha and Tao Wolf, so he didn't think that they were using all their strength, so he asked Chen Feng how he could see that those ghosts were not using all their strength.

Chen Feng analyzed: "If they really use all their strength, then their casualties should not be just that, I feel that their purpose is not to kill the other party, but to fight for the entrance and exit of the base."

"In that case, they're pretty friendly with their companions." Ma Yuanliang commented.

Chen Feng nodded, and then said, "But in this case, the time for all of them to enter the stone chamber group will be delayed, I don't know if it will affect our plan."

"It's okay, don't pay attention to them, we just do what we have to do, and ......" Ma Yuanliang reminded: "Pay attention to the exploration outside the defense area, and see if there are any other black demons or pottery wolves entering our defense area, as well as other types of ghosts."

"Yes, I've arranged it."

For this reason, Chen Feng used communications to contact the reconnaissance team that had gone to the defense area to investigate the situation and asked them about the situation there.

There were a total of three reconnaissance teams that carried out reconnaissance operations outside the defense area, one was west of Yangchong County, the other was east of Shantong County, and one was near Ningxian City.

The reconnaissance team located in the west of Yangchong County has detected the black demons that are still waking up on the ice, the density is very sparse, and of course there are not many in number, that is, occasionally you can see only the black demons coming out of the ice and then rushing to Yangchong County.

The situation is the same in the east of Shantong County, where it generally looks like there are not many pottery wolves in the wild.

The calmest place is in Ninham City, and I haven't seen any movement of the winged snake there from beginning to end.

Chen Feng quickly turned his attention to the battle at the entrance and exit of the base, observing the battle between the Black Demon and the Winged Serpent, trying to find the comprehension of the Yuan Technique from their battle.

Until midnight, Wang Yi rushed back from the material storage area, got some supper, gave Chen Feng a copy, and saw the battle at the entrance and exit of the base on the monitoring wall.

Wang Yi couldn't help but ask Chen Feng, "What's the situation?"

"Black Devil and Tao Wolf are fighting each other." Chen Feng took the bowl and chopsticks and ate a few bites of noodles, and continued: "When the Tao Wolf rushed to the top of the entrance and exit of the base, the black steam was entering, and then the two sides fought, and in the end, no one on either side could enter the entrance and exit of the base."

"How long have they been fighting?"

Chen Feng raised three fingers as he enjoyed his food.

"Three hours?"

"Three hours and ten minutes."

"Oh." Wang Yi kneaded his chin with his hands and thought deeply against the monitoring wall.

Chen Feng then said, "Guess how many of them died in this battle in total."

Wang Yi looked at the fierce battle screen on the screen and said, "According to their way of playing, they will have to die out about tens of thousands."

Chen Feng shook his head.

Wang Yi asked, "More or less?"

"That's a lot."

"Thousands?" Wang Yi himself didn't believe that it would be thousands.

Chen Feng shook his head again.

Wang Yi was stunned and said, "Is it a hundred?"

"Maybe it's not even a few hundred, and according to the scouts' scouts, they rarely see Tao Wolf and Black Devil die in battle."

Chen Feng then added to his previous analysis of those ghosts, believing that they would not kill their kind, except in special circumstances.

Wang Yi said thoughtfully: "Feelings are like this."

"Well, whether they fight or not won't have much impact on us, it's just that the departure time of our second echelon may be a little later." Chen Feng saw Wang Yi walking back and forth, and then asked, "What, are you worried that the second echelon will leave too late?"

"No, I just wondered if we should go and have some fun."

"Huh?"

Wang Yi explained: "When those ghosts are almost there, I think there will not be much left of their Yuan Power at that time, and it is time to train the combat ability of our team by pulling a team of ghost soldiers there to clear the field."

"No kidding, even if they don't have much yuan power left, their number is tens of millions, how many ghost soldiers can you pull out, thousands? Ten thousand? ”

Wang Yi said indifferently: "The quantity is not important, the important quality, in terms of the ability of our ghost soldiers, there should be no danger, it's a big deal to run back when the time comes."
