Because the glyph is activated for the first time, the big glyph only costs 20,000 XP, while the small glyph only costs 10,000 XP.

However, in the future, the experience value consumed will be doubled every time you change it, so Wang Chen will not easily change the glyph unless it is absolutely necessary in the future, lest because of too many modifications, the glyph will not only not be able to become his own help, but will become his own burden.

"No. 4, can I still use the exchange function to exchange for any skills to improve my strength?" Wang Chen looked at the 350,000 experience points in Super Brain No. 4 and asked No. 4.

He also learned to be obedient, and wanted to spend all his experience points, so as not to think of asking No. 4 for help every time like before.

"The host must wait until the experience consumption reaches 2 million before they can get a second chance to exchange skills and directly improve their skills." However, this time No. 4's answer made him a little disappointed.

However, since this is the case, there is no need to keep these experience points, so although Big Stupid Bear can't directly contact the alien corpse for the time being, and he doesn't do anything when defending the city, he still spent 70480 experience points to increase Big Stupid Bear's level to level 28.

Because it is estimated that the situation will be more difficult tonight, and if something happens, the big stupid bear can play some role, at least it can be used as a meat shield, right?

However, Wang Chen decided to hunt as many corpses as possible at night, and scrape together 1 million experience points as soon as possible so that he could exchange a special biological space for the big stupid bear, lest it lose its life when the situation develops beyond control.

Although his relationship with Big Stupid Bear is completely incomparable to Bai Xue, he has been together for more than a month, and if he can save his life, he will definitely do his best.

After all, his soul consciousness came from the earth, and he couldn't directly let his combat partner who had been with him for more than a month be sent to death so cold-blooded and ruthless, even though this combat partner was just a pet.

After raising the level of Big Stupid Bear, Wang Chen thought about it and sent Xu Cheng a water milk, in addition to Dong Hua's face, he did this mainly to consolidate the relationship between them, if Xu Cheng could survive this time, he would definitely spare no effort in the technical support of the secret base

Since about nine o'clock in the morning, the sound of missile explosions outside the base has not stopped, and it is obvious that the airships of the Central Continent base have been destroying the alien corpses as much as possible to relieve the pressure of defending the city of the desert green boat base.

Since the government ~ government of the Desert Green Boat Base may issue the latest order at any time, Wang Chen did not dare to transfer his consciousness to the earth, so he did not rest well this day. Fortunately, with the current attributes of his body, even if he doesn't rest for a day and a night, it won't have the slightest effect.

At four o'clock in the afternoon, Wang Chen and Jiang Weiyong received the latest order from the base government ~ government, saying that they were asked to go to the defense area of the second squad yesterday to assist in defense. Seeing the latest dispatch Wang Chen, it was nothing, but Jiang Weiyong began to greet the family members of the leaders of the base government~ mansion.

There is no doubt that the most difficult position to defend right now is definitely the defense zone they are going to. Because the second squad has been almost completely wiped out, the personnel stationed there now will definitely not be those well-trained soldiers, but a group of ordinary evolutionaries as a reserve.

"You don't have to be too pessimistic, if it is as you said, that section of the city wall will definitely not be able to hold it, so the base government ~ government must have other arrangements, otherwise there is no point in defending the city at all." Wang Chen looked at Jiang Weiyong, who was usually very peaceful, and scolded his mother there, and couldn't help but comfort him with amusement.

Maybe he felt that what Wang Chen said had some truth, or maybe he didn't want to arouse Wang Chen's disgust, Jiang Weiyong smiled embarrassedly after listening to Wang Chen's words, picked up Jiang Weijia and followed Wang Chen and walked towards the Xicheng city wall.

After Wang Chen and his entourage arrived at the city wall to be garrisoned, they found that the jungle outside the base had almost completely disappeared, and there were flames and smoke from trees everywhere.

And the empty space outside the city wall that was originally occupied by alien corpses, at this time, only a few alien corpses were scattered under the root of the wall, tirelessly doing the useless work of attacking the city wall.

The rest of the people who had already arrived at the city walls looked at the smoke and fire around the base, and the few corpses left under the walls, and thought that the crisis at the base had been resolved, and almost everyone except the military was ecstatic to celebrate the aftermath of the disaster.

Wang Chenzou frowned and smelled the strange air mixed with the smell of meat, scorching smell, and thick smoke, and looked at the crowd of people who were celebrating with the crown, but a haze flashed in his heart.

Things will definitely not be so simple, if the crisis is really lifted, the base government ~ government will not be so laborious to transfer them to the city wall, and all the soldiers look like they are in full battle, so the alien corpses will inevitably continue to attack the city tonight, and the offensive is not necessarily weaker than yesterday.

What really worries Wang Chen is that now the natural barrier of the jungle outside the base has actually been destroyed by the humans themselves, if there are so many alien corpses attacking the city tonight and last night, it is likely that there will be more piles of alien corpses formed during the siege.

And because there is no barrier from those dense trees in the jungle, the support of the alien corpses will definitely be faster, and the attack will definitely be more fierce during the siege.

"I hope that the support force of the Middle-earth base can cut off the follow-up troops of the alien corpse, otherwise it will be really difficult to hold the base tonight." Wang Chen thought gloomily in his heart.

As time passed, more and more alien corpses came out of the jungle full of flames and smoke outside the base, and the number of charred corpses under the city walls also increased.

By the time the blood moon rose two hours later, the clearing had been covered with a thick layer of charred corpses, and at this time, those who were celebrating on the city wall finally understood that the battle against the alien corpses was not over, and they all slowly fell silent.

Soon after the blood moon rose, the incessant snoring of strange corpses could be heard in the thick smoke to the west of the base, and Wang Chen used the Eagle Eye Technique, which was already able to see the situation ten kilometers away, in the direction from which the sound came from.

I saw that ten kilometers away, a dense tide of corpses with almost no gaps continued to pour towards the base, leaving no grass everywhere they went, and even the original huge trees were brittle due to the fire, and they were directly hit by the third-order giant corpses mixed in the corpse tide - the saboteurs.

The flames and smoke in the jungle vanished at a speed visible to the naked eye, replaced by a tide of corpses with no visible edges.

Soon the corpse tide appeared in the field of vision of everyone on the city wall, watching the corpse tide surging towards the base in such an unstoppable posture, almost everyone's faces became a little pale, and even Wang Chen's face became very solemn. (PS: It's just late, sorry!) ）
