A legion burst out at the beginning of the super card system

Although there are many zombies in the cable factory, there are very few evolved zombies. A few black iron three-star evolved zombies appeared, but they were all shot and killed by Yisuo and the other fours, contributing a few vitality cards.

Chu Mu got the vitality cards from the evolved zombies, and noticed that there were special cards in these vitality cards.

"Ding, I found a special card, an advanced card, do you want to use it?" The voice of the system prompt appeared in Chu Mu's mind.

"Use!" Chu Mu would not give up any chance to make himself stronger, he used the advanced card.

Chu Mu is now a three-star black iron, and if he advances, he will reach a four-star black iron, so his legion card will naturally become a four-star black iron, and the corresponding legion fighters will also be promoted.

"Ding! The host has used the advanced card, and the success rate is only 30.00%, but the host can choose to devour other vitality cards to increase the rate of advancement." The system's prompt sound appeared in Chu Mu's mind again.

Chu Mu was taken aback, he didn't expect that there is such a thing as a success rate for advanced cards.

In order to increase the success rate, Chu Mu endured the pain in his heart and devoured a few vitality cards that had not yet been identified.

"Ding! The host chose to devour other vitality cards to increase the success rate of advanced cards. Now the success rate of advanced cards has reached 70.00%. Do you want to advance?"

"Advanced." Chu Mu felt that the success rate of 70.00% was already very high, so he chose to advance.

"Advancement begins!"

After the system's notification tone, Chu Mu's body shone with light, but only Chu Mu could see the light, and no one else could see the light.

After the light shined, Chu Mu was promoted from three-star black iron to four-star black iron.

After Chu Mu was promoted to the black iron four-star, he checked his legion soldiers.

As the head of the legion, Hong Zhong was promoted to the Black Iron four-and-a-half-star, and the rest of the legion soldiers were also promoted to the Black Iron four-star, and their strength has been improved.

Chu Mu walked to the storage area of ​​the cable factory, saw that there were very few zombies in the storage area, and began to command the legion soldiers to wipe out the zombies,
Not long after, the zombies in the storage area were cleaned up, and Chu Mu ordered people to drive the truck in.

It's just that there is a problem that needs to be solved right now.

"These coils of steel cables are huge and heavy. How do we transport them onto the truck?" Chu Mu asked the veterans who followed.

"Xiao Chu, if we want to load these steel cables, we need to activate the spreader." A veteran pointed to a gantry in the storage area.

"Sling, do you know how to use it?" Chu Mu is considered a well-informed person, but he is really a layman on how to load steel cables.

"Xiao Chu, you underestimate us veterans. In our railway barracks, what kind of equipment has never been seen before. This is pediatrics."

The veteran who talked to Chu Mu is also a small leader. His name is Du Wei, and he works as a maintenance worker in the convoy, so he is very familiar with mechanical operations.

After some debugging, Du Wei has mastered the principle of the spreader, and operated the spreader to load the steel cable coil on the truck.

In a short time, the three vehicles loaded with enough steel cables, as long as the food and steel cables were transported back to the home of the Iron Soldiers, the task was considered completed.

"Who?" At this moment, Chu Mu suddenly noticed a man in black standing in a corner of the storage area.

"You guys are very strong, which base are you from?" The man in black had a loud voice, and his voice could be heard from far away.
