However, this was just Li Mu's speculation, he didn't have any evidence, and there didn't seem to be anything in the school now that was worth using so much power from the other party. Li Mu thought about it and didn't tell the other party his guess.

At night, the campus fell into a rare silence, and Li Mu had been keeping an eye on the dynamics of the patrol team in the communication channel, but nothing happened until the sun was about to rise.

"Haha, great, those rats in the dark are really afraid of us!" The patrol team said excitedly, finally their all-night efforts were not in vain.

Unfortunately, the good times did not last long, and just when everyone was rejoicing in this victory, a huge explosion sounded from all sides of the school.

Fortunately, Li Mu activated a lot of defensive trap cards before falling asleep, and there is a very powerful place compared to the spell card, that is, the trap card will be automatically operated as long as it is activated, and Li Mu does not need to bother. Moreover, Li Mu's trap cards also use energy-saving modules, which consume less energy and energy before they are activated, and Li Mu's energy-saving modules can be almost non-consuming for twenty-four hours.

The explosion occurred from Li Mu's dormitory next door, and when the blast wave approached Li Mu's warning range, his trap card attack was powerless and automatically opened to stop the explosion. In fact, even if this trap card is invalid, Li Mu has also prepared other kinds of mystery and trap cards, and safety is still very important to Li Mu.

"What's going on!" Hong Tianbao didn't sleep much all night, and when he heard the explosion, he reacted immediately, and then came to Li Mu's room.

"It seems that we underestimated each other, they don't know when they planted a time bomb in the school, the reason why they didn't show up last night was not because they were afraid of us, but because they had already prepared an attack plan......" Li Mu had 10,000 alpacas running over in his heart, and these people did not play cards according to the routine.

"It seems that they have to take the initiative, otherwise who knows what tricks they will use next time." Li Mu looked at the classmates who were blown into minced meat in the dormitory next door, and he was also very angry in his heart. Although these people have an average relationship with Li Mu, they have been together for a few months, and these people have not done anything wrong at all, they are just innocent victims.

"Is it going to be over...... Hong Tianbao said in disbelief, recalling what the thin man said yesterday, and now he is very scared.

Li Mu and Chu Yun quickly changed their clothes and gathered the team, now there are casualties everywhere in the school, they must rescue these wounded first. Li Mu and Chu Yun's team was lucky, there were not many people affected last night, the two brigades together were incapacitated and the chief engineer was only nine people, Li Mu reorganized them, and then took out twenty one-star silver cards for rapid healing and handed them over.

It's not that Li Mu is stingy, his cards are too complicated, and there are only a few high-level healing cards in total, so he naturally keeps them for his own use, and it is already very conscientious to be able to provide so many scarce healing cards for free.

"You still follow the squad to rescue the wounded, each squad has a treatment card, you take turns to use this treatment card to save mental energy, serious injuries are treated as minor injuries, and minor injuries are left alone. I discussed with others just now, our two teams are responsible for Building 1 to Building 5, and you are responsible for one building for every four teams......" Li Mu directly arranged for Chu Yun's team, but Chu Yun and everyone had no opinion, and quickly took Li Mu's card and started to act.

The buildings of this world are much stronger than those of the earth, and these Black Cross people don't know much about the structure of buildings, so although they planted a lot of bombs, they didn't blow up the building, otherwise things wouldn't be so simple.

After Li Mu arranged everyone, he went back to the dormitory alone to replenish the cards, and the cards he wanted to make this time were more special.

Card Name: Fountain of Life (Warcraft)

Star Rating: Two-Star Gold Card

Type: Building Card

Attributes: Fee 2 / Attack 0 / Resistance 10

Skills: 1. Healing, drinking the Fountain of Life will heal the wounded.

Notes: 1. The fountain expires after ten minutes of leaving the fountain, and the fountain of life consumes one durability every ten minutes of existence.

2. The Fountain of Life produces spring water based on energy card consumption. ”

This is Li Mu's first time making a building card, originally he wanted to make a base in the League of Legends, but that seems to be too shocking, or this spring of life is reliable. Looking at the attributes of the cards, Li Mu made two more fountains of life and rushed to the rescue site, this time the rescue Li Mu Their primary goal is to save the lives of the wounded, and then the school and the federation will have a headache.

"Hey, in fact, if it weren't for the clash that happened yesterday, Hu Dong and the others wouldn't have been so hindered, maybe they would have found a bomb in the dormitory." Li Mu thought so in his heart.

According to what Huang Zhenbo said yesterday, most of those black crosses were individual actions, so this large-scale explosion is likely to be ambushed by the Grim Reaper team a long time ago. Those who went it alone must have been warned by the Reaper team that they didn't act last night.

"You're Anna in second grade, aren't you?" Li Mu saw a girl wearing a gold-trimmed nun dress treating the wounded with a healing card, and recognized the other party's identity at a glance. After all, such a lavish nun dress is only used by the money-worshipping church.

"Huh? You are...... Li Mu? Anna wiped the sweat from her forehead after treating a wounded person, and there were many wounded people who were carried down and waiting for the ambulance, and Anna and several other trainees simply did not have time to treat them.

"This one is for you, the efficiency is high. You tell them to move the wounded from the dormitories in the neighborhood, and I'm going to the other side. Li Mu handed the card to Anna and left, leaving Anna at a loss to stand in place.

"It's ...... Fountain of Life? Anna looked at the name of the card with some confusion, it sounded like a card like a healing potion, but this kind of card is usually consumable, and it is not as good as a healing spell card in the current situation.

"Wait, this is a building card? Building cards with healing effects?! Anna's eyes widened when she saw the card's attributes.

This kind of card is actually similar in this world, for example, Chu Yun's environment card has an attack effect, and Li Mu's card just changes the site and environment into a well-shaped building, and the effect is to restore life.

What Li Mu didn't know was that this kind of card was very rare, usually only the elite units in the army were eligible to use it, and most ordinary people didn't even know that there were such cards.

Suspiciously, Anna inserted the card into her card instrument, and then picked an empty spot to summon the Fountain of Life.

"So big!" Anna watched as the fountain of life, which was more than five meters in diameter, fell into a stupora again, and the blue liquid was constantly bubbling from the spring, and the mere smell of it made Anna feel refreshed.
