Two days passed in the blink of an eye, and the nearly one million zombie corpses at the gate of the camp were basically disposed of, and the entire camp gradually returned to normal.

And Yang Yifei also accompanied Tao Duoer in the room for two days, in these two days, Yang Yifei was completely in a state of not eating, drinking, sleepless, and even his body never moved, Li Mengqi and Xuan Yuran didn't pay attention to talking to him, and they didn't look at the food they sent, just sat quietly on the edge of the bed, looking at Tao Duoer lying in the ice coffin stupidly.

Every day, a team member will come to freeze Tao Duoer's ice coffin, otherwise the ice coffin will melt, so the temperature in the room is basically kept at about minus 10 degrees.

Although the game system is temporarily lost, fortunately, the physical fitness is still much stronger than that of ordinary people, otherwise the low temperature in the room alone is enough to make an ordinary person freeze to death, let alone not eat or drink.

But even if he didn't freeze to death, Yang Yifei's condition was not much better, his hair and eyebrows were frozen, and his whole face was completely blue and purple, if he didn't still breathe, he would be no different from a dead person.

Li Mengqi and Xuan Yuran, who were outside the room, looked at Yang Yifei's appearance, unspeakably distressed, and the two girls also wanted to accompany Yang Yifei and Tao Duoer in the room, but Yang Yifei only let the team members who froze the ice coffin every day go in, and in desperation, the two women could only stay outside the room with Li Mingjie and others.

Regarding Yang Yifei's situation at this time, the two daughters and Li Mingjie and others did not have the slightest solution, Yang Yifei was heartbroken, and could only rely on Yang Yifei to come out by himself......

Suddenly, I saw Yang Yifei in the room, the ice cubes on his hair and eyebrows, which had been frozen, exploded, his blue and purple face returned to normal, and a force returned to his body again, and the game system was updated!!

Standing up and moving his somewhat stiff body, Yang Yifei looked at Tao Duo'er in the ice coffin and said softly: "Duo'er, Brother Yifei is going to do business, I will come to see you often, you have to be obedient!" With that, he turned around and opened the door and walked out. There are still many things waiting for him to do, and a lot of responsibility is weighing on him!

"One Fly!"

"Fly!"

"Fat plane!"

As soon as "......" saw Yang Yifei, Li Mengqi and the others who were guarding outside suddenly stood up, their faces full of worry.

Looking at the familiar faces in front of him, Yang Yifei said softly: "I'm back!" ”

Just such a soft sentence made the two girls cry with joy, and also made Ma Quan, who originally regarded Yang Yifei as a god, excited, because the god of war who regarded millions of zombies as nothing, and killed mutant beasts like chopping melons and vegetables, came back!!

After gobbling up the food of ten people and telling the two girls not to disturb, Yang Yifei sat on the sofa and turned on the game system that he loved and hated.

As soon as I opened the game system, a prompt sounded: "The player has reached the advanced requirements, do you choose to advance, yes or no?" ”

After choosing yes without hesitation, the system prompt sounded again: "Congratulations to the player for successfully advancing to the current level of level 4 and level 0." After the player successfully buys the price, he can get 100 fixed points and 1000 free attribute points for each level upgrade! ”

Hearing this prompt, Yang Yifei was so shocked that he almost fell directly from the sofa, after this advancement, it was really terrifying, 100 fixed points per level, and 1000 free attribute points, how could he not scare him?

Putting aside the distracting thoughts in his mind, Yang Yifei opened his attribute panel: Name: Yang Yifei

Level: Level 0 of the Fourth Order

Strength: 1091

Dexterity: 1465

Mental Power: 468

Stamina: 478

Talent Skills: Eye of Detection (not advanced), Intermediate Berserk (advanced) Sword Slash (current level: 1, proficiency 10000/10000, this skill can be upgraded, not advanced) Beast Trapping (can capture beasts as pets, the higher the level of the beast, the lower the success rate, this skill cannot be advanced) Electric Shock (current level 1, proficiency 10000/10000, this skill can be upgraded, cannot be advanced) Sky Dance (this skill cannot be upgraded, cannot be advanced) Intermediate armed color domineering (this skill can be advanced, Cannot be upgraded)

Upgrade XP: 0/5 billion

Free Attribute Points: 50.

When he saw that it would take as much as 5 billion experience to upgrade to the fourth order level 1, Yang Yifei directly burst into foul language: "Nima, it's really a cheat......

However, before Yang Yifei finished speaking, the system prompt sounded again: "The player's skill "Intermediate Berserk" has reached the advanced requirements, and the advanced requires 10 million gold coins, players please choose whether to advance, yes/no? ”

Hearing this prompt, the haze just now disappeared in an instant, and the rage can be said to be completely Yang Yifei's bottom-of-the-box skill, and now that he can advance, he will be more sure to destroy all the zombies!

Of course, the 10 million gold coins also made Yang Yifei's heart twitch completely, and he didn't know if he had so many gold coins to advance. I opened my backpack a little weakly and looked at the gold coin number in the bottom corner: 22.9 million.

Looking at this number, Yang Yifei was relieved, and without hesitation, Yang Yifei directly clicked Yes.

The system prompt sounds: "Congratulations to the player for successfully advancing the "Intermediate Rage" skill ......"

Hearing the prompt that the advancement was successful, Yang Yifei couldn't wait to look at the advanced successful skill: "Ultimate Rage: The player opens this skill, all attributes are increased by 1000%, the duration is three minutes, the cooldown time is seven days, the skill is over, all attributes are reduced by 100%, the duration is 6 hours, this skill has reached the highest level, it cannot be advanced, it cannot be upgraded, and the required level is level 5." ”

"Hiss......" After reading the skill introduction, Yang Yifei directly gasped, and all attributes were increased by 10 times, which is completely the rhythm of heaven! He didn't expect that there would be such a big change after advancing to "Ultimate Fury".

After all, it used to be seven days of cooldown, and there were 48 hours of weakness, but now the cooldown time has become one day, and the most important thing is that the sequelae have been shortened to 6 hours, which is the most important thing.

Yang Yifei didn't know, the surprise was far more than that, because the system prompt rang again: "The player's skill "Sword Slash" proficiency has reached the upgrade requirement, and the upgrade requires 1 million gold coins, does the player choose to upgrade, yes/no? ”

"The player's skill "Electric Shock" has reached the upgrade requirement, and the upgrade requires 1 million gold coins, does the player choose to upgrade, yes/no? ”

Without any hesitation at all, Yang Yifei directly clicked yes, 10 million gold coins were spent, do you still care about these two million!

"Congratulations to the player for successfully upgrading the "Sword Slash", the current level is 2......"

"Congratulations to the player for successfully upgrading the "Electric Shock Technique", and the current level is 2......"

Yang Yifei hurriedly turned his attention to the two skills that were successfully upgraded: Skill Name: Sword Slash, this skill is a long-range attack skill, which needs to be equipped with a weapon (emitting sword qi with a weapon in his hand, the effective killing distance is 30 meters, the mental power is consumed by 10 points, the cooldown time is 5 seconds, it can be upgraded, it can be upgraded to level 3, the current level is level 2, this skill needs to be equipped with weapons, the level requires three levels, and the current proficiency is 0/100000. ）

"Skill Name:"Lightning Strike Technique", a single long-range attack skill, requires a weapon (can instantly summon a lightning bolt to attack the enemy, there is a 10% chance to paralyze the enemy, the attack range is 30 meters, consumes 15 points of mental power, the cooldown time is 2 seconds, the skill can be upgraded, the current level is 2, the proficiency is 0/100000, and it cannot be advanced)

"Uh......" After reading the introduction, Yang Yifei was completely stunned by the successive surprises at this time, the harvest of this advance was too great, but at the same time, Yang Yifei's heart was also dark, and he thought of the scene where Tao Duoer stood in front of him again.

"If these skills had been upgraded earlier, I would have been able to easily kill Zhang Pengjie, and Duo'er would not have died to save me!" Yang Yifei lowered his head and muttered......

And just as Yang Yifei was immersed in surprise and gloom, at the same time, three figures were coming in the direction of the camp at an unimaginable speed!!
