Throughout the night, Lin Fei barely rested, accompanied only by the company of the troops he recruited and one battle after another.

Three hours after leaving the witch's hut, Lin Fei was lucky enough to find several resource treasure chests, and after scraping away the resources in these treasure chests, Lin Fei was finally able to build a second-level creature recruitment station.

The previous Claw Demon was a first-level creature, and the second-level creature was a lava iron demon, with a combat power of 10,300 points, but it was much stronger than the Claw Demon. After having second-level creatures, Lin Fei still didn't carry those clawed demons before, but because the distance was a little far, he didn't want to waste time going back to lead the troops, and if he let those clawed demons come by themselves, he was afraid that he would encounter wild creatures on the road and suffer unexpected losses.

Now, Lin Fei had reached an area very far away from the main statue, which was full of mountains and dense forests, but Lin Fei did not intend to continue forward, but turned north, preparing to return to the main statue in a large circle.

After marching north for a while, Lin Fei encountered some low-level troop recruitment stations, naturally, Lin Fei, who was now short of troops, wanted everything, and attacked and occupied all of them.

So a few hours later, Lin Fei brought more troops, but except for the Polar Bear Warrior and the Liukou, the others were all low-level troops with a combat power of 8,000 to 9,000.

Elite skeleton soldiers, ancient amphibious fishmen, the number of these two low-level troops is about four or five respectively, and when combined, it is also a large combat power.

It's just that what annoys Lin Fei is that these troop recruitment points are all distributed in various areas, and even if they occupy themselves, if they don't come in person, it will be difficult to continue to recruit troops.

Bypassing a large area of mountains and mountains, Lin Fei looked ahead, but his brows moved.

He saw a large brown rock.

This rock is by no means a natural formation. At least. The image of a giant monster's mouth is not natural. Looking closer, Lin Fei saw that there was a hole in this rock, which went straight underground.

"It's a lot like a passage!"

Lin Fei's heart moved. Just as he wanted to keep closer, he saw seven or eight huge 'Ancient Three-Headed Jiao Beasts' guarding the entrance of this passage.

This ancient three-headed Jiao Beast Lin Fei had seen before, and it was three at that time. Guarding a treasure chest, it was only after seeing the combat power of this ancient three-headed beast that Lin Fei carefully considered it and chose to give up.

Because the combat power of these monsters is as high as 25,000, three such monsters may be even more powerful than that one demon dragon, Lin Fei is not a fool, and now he has this little strength. Rushing up can only be sent to death.

The situation in front of him was the same, the three Lin Fei didn't dare to touch them, let alone these seven or eight.

"Yes. I can't afford to mess with it. You can always afford to hide! Lin Fei was extremely unwilling in his heart, the passage that seemed to lead to the underground world could definitely lead him into a new realm. It's just that he can't think about it now, unless he has enough strength in his hands to kill those seven or eight ancient three-headed beasts.

After marking the location of this underground entrance on the map, Lin Fei bypassed this place and continued to walk forward.

In front of it was a long and narrow valley, the ground was dry and cracked, and occasionally you could come across many dry bones of Bai Sensen, and the night wind blew through the bones, making a whining sound, and it was obvious that this was a barren valley of death.

After entering this canyon, Lin Fei encountered strange things.

He saw a street sign.

The sign was placed across the ground and read, 'Warning, Ancient Prison ahead, no further onwards!' '.

It was the first time Lin Fei had seen this kind of hint in the ancient battlefield, and after crossing this wooden card, Lin Fei was attacked by some skeleton soldiers who came out of the ground.

Fortunately, the combat power of these skeleton soldiers is not high, only about 8,000, but it is relatively easy to deal with with Lin Fei's current strength.

As he continued to move forward, Lin Fei encountered more and more ambushes, and most of the ambushers were undead skeletons crawling out of the sand.

The more this kind of attack, the more questions Lin Fei had in his heart, obviously, there was something important in front of him, otherwise it would be impossible to have so many ambushers.

So, Lin Fei did not retreat, but continued to move forward.

Finally, at the end of the valley, Lin Fei saw a black cell.

The cell was surrounded by iron bars on all sides, but inside was a dark shadow, and in front of the cell, there was a wooden sign that read 'Ancient Prison'.

Lin Fei knew that these were all suspicious formations in the mission world, and if he wanted to know the most authentic hints, he only needed to touch this cell with his own hand to know.

So Lin Fei did just that.

"After a long journey, you have reached such a Death Canyon, here, you found a hero imprisoned in an ancient prison, do you want to open the cage and release this hero?"

Looking at the prompt, Lin Fei was slightly stunned, what was a 'hero', Lin Fei could guess how much. And the prompt that appeared next also confirmed Lin Fei's guess.

"Heroes are a very special 'unit' that can learn magic, equip strategic items, lead troops to fight in the north and south, and at the same time can help you collect resources and recruit troops!"

Seeing this prompt, Lin Fei's eyes lit up. At that moment, he chose to release the hero without hesitation, and soon, a virtual panel appeared in front of Lin Fei.

On this virtual panel, there are actually six cards, each with an avatar and a large introduction.

Lin Fei was curious, so he naturally looked carefully. The six cards feature the heads of six heroes, male and female, with different appearances and names. And the most obvious thing is the color of the name.

There are three that are white, two green, and one blue.

And after a closer look, Lin Fei finally understood what this meant, these six cards represent six heroes, and one must be chosen after the six cards are scrambled and flipped.

In other words, it all depends on luck.

Naturally, the abilities of the six heroes are high and low, and the one with the white name is the most common hero, with average ability and no skills. Green is a well-made hero with higher abilities than the white normal, carrying a passive strategic skill. The blue hero is an excellent hero who carries a passive strategic skill and an active skill.

Naturally, there are not these three qualities of heroes, and above the blue excellence is the purple perfect quality and the more advanced golden legendary quality.

It's just that it is clear that there are no heroes of the latter two qualities in this prison.

After the rules were clarified, Lin Fei chose to prepare to draw, and saw that the six cards representing the hero flipped over, and then quickly changed positions. This speed was so fast that it was impossible to see it at all, and after the six cards changed for a moment, they stopped, waiting for Lin Fei to choose.

Lin Fei didn't know which hero these six cards with the same touch on the back represented, if he wanted to choose, he was simply trying his luck, and since this was the case, Lin Fei didn't plan to think about it, but he chose one by feeling.

Suddenly, the card flipped over.

Lin Fei saw that his luck could only be average, and he didn't choose that blue quality hero, but only chose a green one.

"Green is green, it's better than white, and it's a hero from white!" Lin Fei comforted himself, and the next moment, the virtual panel disappeared, and then he saw that the originally solid and gloomy prison fence began to turn into puffs of black smoke and disappear, and then a middle-aged man in armor walked over.

"My lord, Carlos pledges his allegiance to you!"

Obviously, this middle-aged man is called Carlos, a down-and-out knight with a combat power of 9800 and carries a passive skill called 'Basic Tactics'.

Basic tactics that can be used to control the opponent's troops that are effective against the enemy, and use the terrain to fight.

With this hero, Lin Fei is quite satisfied, because the troop recruitment points he attacked along the road can be recruited by Carlos, and at the same time, Carlos can also lead troops to explore new areas and help him collect resources.

Lin Fei didn't know if the other two contractors had gotten a hero, but no matter what, as long as they got a hero, they would obviously have a great advantage.

And Lin Fei also knew that the main statue could also create a place to recruit heroes, called a 'tavern', but the construction of the tavern required 1500 units of gold and 20 units of wood, Lin Fei had not built it yet, and if he recruited heroes in the tavern, he would also need 2500 units of gold, so it can be said that it is easy to build but difficult to recruit.

Lin Fei didn't know the specific situation, but obviously, if he invested all his resources in building a tavern and recruiting heroes from the beginning, it would definitely take a long time, and it would definitely outweigh the losses, so Lin Fei didn't choose to build the tavern first.

Next, Lin Fei thought of a good tactic, but he handed over all his troops to Carlos, including the Celestial Stone Shield and the Celestial Stone Sword. Carlos's passive skill basic tactics can greatly exert the power of the troops, so Lin Fei feels that it is more suitable to lead the troops to extricate themselves from the new area.

As for Lin Fei himself, because of his excellent mobility, he is more suitable for recruiting scattered troops.

In this way, Lin Fei can give full play to the advantage of his speed, and a few hours later, Lin Fei once again brought a large number of troops in his hand, including super water element, polar bear warriors and some low-level troops, and Carlos also captured some resource points in a row, and his strength slowly accumulated and became stronger and stronger.

Time passed quickly, and soon the sky began to brighten, and the next day Lin Fei returned to the main statue base and built some buildings with the resources at hand. And the batch of claw demons and lava iron demons produced before, Lin Fei also carried them all, anyway, the main statue has a defensive wall, and he is not afraid of other enemies attacking in the short term.

In this way, the strength in Lin Fei's hands has reached a very considerable level, and if the troops carried by Carlos are combined into one, it is not impossible to capture the recruitment center of some high-level creatures.
