Casting spells permanently increases magic power, and my holy light increases by 10 billion

"Captain, the situation seems to be getting serious. The monsters in the east are getting higher and higher in level, and they are charging in an organized manner. There is even a group of special ranged attackers harassing our healers."

"The casualties are getting higher and higher. At this rate, if we want to hold the second front, we may have to pay with human lives! Many people have already thought about retreating."

Listening to the report on the casualties, Zheng Tian's face was very serious. He really wanted to keep all these monsters in the abyss, but he didn't want to fill them with human lives.

The high-level explorers themselves are more valuable than each other, and the explorers who are willing to come to defend the front line of the abyss are a group of people with faith.

If they are allowed to fill the battlefield with their lives, it would be better to simply abandon the front line and fight guerrilla warfare later.

"How many teams are there behind us to support us?" Zheng Tian asked the messenger.

"There are already more than a thousand people coming to support us, and there will be hundreds more coming later. However, the level of those coming later will be slightly lower, because of the level difference between them and the monsters, the main people holding the front line are those professionals above level 70."

In the abyss, the advantage brought by a high-level professional is very obvious, so basically most teams will have a core to build the team.

After learning about the situation in the abyss, these high-level professionals came here as soon as possible. Although the subsequent teams are willing, they are actually below level 60, and basically will not be of much help to the front line. At most, they will have an advantage in treatment.

"Boss! The support from Mianyang City will arrive in more than two hours. The leader is Luo Cheng. There are 20 people in total, 3 of them are level 79, and the rest are above level 70."

Another person came to pass on the information.

But at this time, Zheng Tian was sensing the battlefield.

He felt more and more dangerous. The Lord BOSS in the distance was getting closer and closer. I'm afraid it won't last two hours and will get close to the battle line.

"Notify each team that if the pressure is too great, slowly start to retreat behind the abyss!"

"The pressure to defend the second front is too great. We will slowly move to the first front, where we have more advantages. In addition, notify all cities to prepare for defense!"

Finally, Zheng Tian issued an order to gradually retreat.

Although fighting in the abyss will block all monsters in the abyss and prevent the battle from spreading to Blue Star, the pressure is getting greater and greater.

If we don't retreat slowly, I'm afraid that many people's psychological defenses will gradually collapse.

The best way now is to retreat to the initial defense line outside the abyss.

The initial direction is the area that took the longest time to build. The battlefield is on the native Blue Star. Although there will be many free monsters escaping when defending against monsters there, it is attacking below from above the cave, occupying the advantage of the terrain and reducing the damage to personnel. The support behind will be less and less visible to the naked eye, and Zheng Tian must be prepared in advance!!......

Following Zheng Tian's order, the teams on the front line breathed a sigh of relief and began to retreat slowly.

The beast tide was endless, and God knew where so many monsters suddenly appeared. Under the pressure of these monsters, even the teams on the front line occasionally had"deserters" who gave up guarding the abyss, thinking that the entrance to the abyss could no longer be defended.

Fortunately, the initial first line of defense could still be used, and many teams were quickly integrated and exchanged.

Zheng Tian personally joined the battle and stabilized the beast tide for a short time.

Time passed little by little, and there were intermittent replenishments and losses of personnel.

At this time, Lu Chen finally arrived at the front line of the abyss.

Looking at the battle at the entrance of the abyss in the distance, Lu Chen was not as worried as he imagined. Instead, he felt a long-lost sense of familiarity.

"The Bazhong Abyss."

Lu Chen looked at the entrance to the abyss in the distance, and a sense of familiarity arose spontaneously. In his previous life, he had stayed in this abyss for more than ten years. He had come to this entrance hundreds of times and witnessed the changes and development of the Bazhong Abyss with his own eyes.

"We have actually reached the entrance of the abyss. Is the pressure in the abyss so great in the early stage?" Lu Chen was a little emotional.

Because from the perspective of later generations, the Bazhong Grottoes should actually be a relatively small abyss.

The strongest abyss lord inside should be around level 95, belonging to the level of a C-level civilization.

In later generations, as people gradually understood the abyss, they actually discovered that these abysses have"civilization" attributes.

Some advanced abyss worlds even have their own writing!!

In the post-abyss era, people even found that some abysses have the breath of otherworldly civilizations.

Therefore, after a comprehensive assessment, everyone also tacitly divided the abyss into multiple levels, which are probably C-level civilization.、B、A、S、SS、SSS is classified like this.

This is not a classification on the data panel, but a human definition. Because the abysses are at least level 50 or above, the lowest level of abyss is rated C.

The Bazhong Grotto is a type of C-level abyss. In other words, in the entire Sichuan Plain, three of the four abysses are actually C-level abysses, and only the abyss to the west of Rongcheng is a B-level abyss, which has been invaded by Blue Star.

"But it is understandable. After all, the Abyss Era has just begun, so it is normal to feel pressure to defend."

After Lu Chen approached, he saw that many teams were seriously defending monsters and trying their best to protect their homes.

This made him look serious.

Even though these ancestors were of average strength, at this moment, it was indeed their lives that created the glory of the future generations.

If it were not for the pioneer corps that continued to fight, human civilization would probably still be scattered all over the Blue Star.

After observing the battle for a while, Lu Chen could feel that the current situation seemed to be more dangerous. The monsters that rushed out now alone had already put a lot of pressure on these teams. If another lord came out, I am afraid that the outermost layer would be breached.

Although Lu Chen did not plan to rush to the front line, the damage reduction at level 45 was too much, and he could not cause effective output.

But if If it was just a healing, Lu Chen felt that he should be able to help them.

So, Lu Chen quickly came to the recruitment office of the Pioneer Corps.

Because there are many teams coming from cities to support.

So you need to report here specifically, and then assign teams.

The largest team on the data panel is a 40-person team.

In later generations, special props were used to build a 100-person team, and generally the gain can be maximized in the team.

Lu Chen felt that with his current strength, it would be best to get a position in Cheng Nan or Zheng Tian’s team to maximize his healing advantage.

But unfortunately, after Lu Chen sent a message to Cheng Nan, Cheng Nan was very busy and had not responded to him yet.

Lu Chen had to join the battlefield in his personal capacity first and talk about it later.
