Rushing into the rudimentary fortifications built by the girls, Firena immediately inflicted a wide range of slow healing and courage blessings on them, and the mercenaries breathed a sigh of relief, and then fell to the ground one by one, glad that they had escaped death.

Immediately afterwards, the leader who had commanded everyone before walked quickly in front of Qin Feng, and after giving him a simple greeting salute, he said gratefully:

"I am the temporary commander of several temporary adventure groups, Naskir, thank you very much for your help, His Royal Highness Qin Feng, and several noble ladies, on behalf of all the members of the adventure group today, I would like to offer my most sincere wishes to you!"

"Okay, Naskir, now that the kobolds' crisis has not passed, there is no need for so many useless etiquette, you quickly organize mercenaries, build a simple fortification as soon as possible, the wall of fire is about to be extinguished, I hope you can also do your best!"

Nodding quickly, Qin Feng waved the staff in his hand again after saying to Naskir, and cast a huge spatial blade on the kobolds who were constantly rushing frantically outside, and now that there was no obstacle from the mercenaries, everyone as magicians could wield their magic to their heart's content.

On the other hand, although he saw that the mercenaries were all shrunk into the wall of fire, the kobold king was obviously very angry, and he didn't intend to stop there, only to see the fighting spirit on his body surging towards the scepter in front of him again, and then let out a long roar towards the sky, followed by an earthy yellow halo, which spread around him again.

The earthy yellow halo was extremely fast, and it spread to the entire cave in a short time, but all the kobolds who came into contact with this halo were dyed with a layer of earthy yellow on their bodies again, and then the kobold king howled loudly:

"Capture those filthy humans alive, and the great Lord Soros will protect us!"

"The great Lord Soros will protect us!" The king, who followed him, howled, and then the kobolds, with red eyes, rushed straight towards Firena's location, fearless to death.

Of course, it was not easy for them to break through the defense line arranged by Firena and the others, with the efforts of more than forty silver-level mercenaries, a simple but decent small fortress was built at a speed visible to the naked eye, and Qin Feng also distributed the quite sophisticated spears in his own space to those mercenaries.

With a sophisticated spear, the mercenary's combat power is instantly multiplied, and using the gap in the fortress, it can also face those who although the yellow light film on the kobold's body can enhance a certain amount of physical and magical defense, but in the face of the class gap, this defense power is also very limited.

However, the advantage of kobolds is not in their sophistication, but in their sheer numbers, and although many kobolds have been wiped out, more kobolds are pouring out of the surrounding mines to join the besiegers.

With a huge advantage in numbers, the kobolds rushed out of the magical attack area where Emer and the others crossed and bravely rushed to the bottom of the rudimentary fortress built by Firena and the others, and several kobold generals tried to dismantle the simple fortifications, but fortunately, Matthew and the mercenaries arrived in time, which was considered to alleviate the urgent crisis.

"Rost is fooling you!"

Standing at the top of the fortress, Firena occasionally cast a soul whip on the kobolds below, and also threw a few third- and fourth-order magic scrolls at the kobolds at close range like throwing grenades.

Although there are many high-level magic scrolls given to her by the lich, they are more of them slightly ordinary low-level scrolls, of which the third to fifth orders occupy a large part, and now is the time to use this thing, and Firena naturally will not miss such a good opportunity to practice.

In this way, the kobolds were caught between the magic and the arrows at the top of the fortress, and the spears at the entrance, and although they could not move forward, they could not go any further.

"Raise your shield and move forward!" However, just as Firena and the others thought that this would be the end, the kobold king's guard outside the fortress came to the front line again, only to see him shout, and then in the eyes of everyone, standing upright with yellow shields on his face, and marching towards the line of defense that Firena and the others had built.

"When! While! While! "The sturdy shield with magical defense not only allowed the kobold guards to break through the attacks of elemental magic, but also caused the well-studded spears to slash a fiery spark when they hit them, leaving the kobolds behind the shield unscathed.

In fact, the kobolds' shield was far stronger than Firena had imagined, and some of the unsturdy spears poked at their backs and even broke in two, forcing the mercenaries to fetch new spears to use.

I saw that the kobolds with shields held those big shields and pressed firmly against the obstacles, and the kobolds behind them used these shields as cover, cutting down the obstacles that were used to cover the people from east to west.

Under their long knives, the simple fortress suddenly seemed crumbling.

"Oops, this fortress is about to fall! Quick, get back into the mines! Sensing a violent shaking beneath her, Firena threw a magic scroll outside, and seeing that the fortifications below were about to be destroyed, she shouted to Matthew:

"Matthew! You lead the shield warriors in the mercenaries to defend the entrance to the cave! If you really can't stand it, you can use the Treasure! ”

"I see, Senpai!" Hearing his master's order, Matthew hurriedly organized those shield warriors, guarded the mercenaries and Firena in the rear, and retreated into the mine.

When everyone in the rear retreated to the cave, Matthew thrust his shield into the hole, and when the kobolds were about to rush up, the magic in their bodies instantly poured out, and then they all converged on the shield.

"The imaginary treasure is suspected to be unfolded / The basis of human reason!"

As soon as Matthew's words fell, a holy light appeared in the center of Matthew's shield, and the white light became stronger and stronger, and in the next moment, a white light was suddenly outlined in mid-air, and the rays were connected with each other, and finally formed a wall of light, firmly blocking the exit of the mine, no matter how the outside attacked, this wall of light did not move.

......Seeing this scene, not only the mercenaries, but even Qin Feng and them couldn't help but be amazed and stunned, you must know that the attacks outside are so dense, and they can stand still under this kind of attack, which shows the terrible defense of Matthew, and at that moment, they left all their doubts about Matthew behind.

"Okay, that's one of Matthew's abilities, let's take advantage of the current stage and figure out how to deal with those kobolds!"
