The few silver high-level skills that were exchanged before were upgraded to the full level, allowing Xiang En to obtain a large number of skill points.

After seeing the horror of the trolls, Xiang En did not flinch, and there were countless skills in the talent book, including many skills with magical effects.

He only had a few basic skills around him when he just left the academy, and he didn't have much time to brush up on skill proficiency and gain more skills when he was on the run.

But now he can brush up on skill proficiency!

With more than forty skill points, it is not a problem to change five or six silver skills.

In the face of murderous trolls, adding a life-saving skill is definitely needed, and then a buff, a debuff, a spell that increases endurance, and finally a control.

The exchange is for Silver Advanced skills, each of which costs 8 skill points.

Regeneration: Consumes 3%~20% mana to restore some of the mutilated limbs.

Earth Elemental Blessing: Consumes 10% mana, causing the target to receive Earth Elemental Blessing, gaining a 12% increase in strength, and reducing damage taken by 10% for 15 minutes.

Spirit Shelter: Consumes 5% mana, increases the target's energy by 2%, and increases mana absorption efficiency by 120% for 3 minutes.

Disease-ridden: Consumes 8% of mana to make the target dizzy, weak, diarrhea and bleeding, etc., and the effect of group casting is halved for 3 minutes.

Silence Field: Consumes 15% of mana, cutting off the target's mana sensing within a 5-meter diameter area, causing the target's mana to drain at a rate of 1% per second, within a radius of 300 meters, for 15 seconds.

Five silver advanced skills, six skill points remaining, and two bronze skills were exchanged for two bronze skills from Xiang Eun.

Flashing + weakness.

Flashing interferes with vision, weakens and inflicts a debuff of -3% on all stats to enemies.

All the skill points are consumed, if it is more stable, Xiang En can wait for the proficiency of these seven skills to be fully completed, and then exchange for a lot of new skills.

In addition, you can also increase the magic content and the upper limit of mental power underground, and when you reach the gold level, you can exchange gold-level skills, and then you can fight against the trolls, and the chances of winning are even greater.

Xiang En thinks so and does so.

The food stored in the tunnels, including the rats waiting to be fed, was enough to get him to the gold level and go out.

At that time, Xiang En's magic and skills can be greatly improved, and there is almost no need to worry about the threat of trolls.

Every day, Xiang En releases migratory birds in the morning to check on the trolls' living conditions.

Trolls know how to farm, they have also fed large tribes, frost trolls live in high mountains and hilly terrain all year round, and the crops they bring are very special, Xiang Eun's eyes immediately glowed green when he saw it.

The trolls' crop is actually potatoes!

Potatoes are so big that they are exaggerated.

Originally, Xiang En was not sure if the things that looked like potatoes and were the size of papayas were potatoes, until Xiang En watched as the troll cut a potato into pieces and buried it in the soil.

The huge potatoes and beef are a pot of potato beef stew.

One more reason to deal with the trolls!

And so, they hid underground, and the trolls planted potatoes, raised yaks, and built houses on the estates.

Trolls have been under constant pressure to survive, and have become extra industrious, cutting down trees after planting potatoes.

After cutting down the trees, they built walls and wooden huts in the style of trolls.

Xiang En's several acres of land that they have cultivated have been reused by the trolls, and the little leader of the trolls who is responsible for planting potatoes is very happy, the cultivated fields have no weeds, and the fertility is okay, and they can be used directly to grow potatoes with a little tidying.

The canals built in the backyard provide them with a steady source of water, and some of the corn stalks piled up on the ground are also very popular with the yaks.

Everything left here is like a gift from the ancestral spirits, giving them a perfect territory.

The only downside is that the usable area of the manor is a bit small, and the trolls' "huts" are very large.

At first, all the trolls were able to sleep on the floor, but after a large amount of wood was transported into the manor, they realized that the manor was still a little small.

They were all living in caves before, and it didn't really matter if they squeezed it, but the troll leader Darusa was now a little inflated.

Now they live in the forest, and a large area around them belongs to their tribe, can you believe it?

Build!

Every troll builds a wooden house!

The forest land is abundant, and there is no need to endure the cold temperatures, and if you don't enjoy it now, Darusa is afraid that she will not have the opportunity to enjoy it in the future.

Darusa's vision skipped over the reclaimed fields and saw the remains of the human structure that stood tall, and the more he looked at it, the more he felt that it was an eyesore, and with a wave of his hand, he asked his men to tear down the rest of the bar, making room for the construction of the troll hut.

While taking care to protect the forbidden vine totem in the middle of the house, the trolls took wooden sticks and stone axes and struck them, and in a few moments, the last two sturdies of the house collapsed!

The scene is like the Mediterranean shaving off the insistence on both sides and completely turning into a bald head.

The trolls began to clear the rubble, and it happened that there was a large pit on the outskirts of the manor where corpses were burned, and the trolls enlarged the pit a little, and the construction waste piled up directly in the pit.

Some of the useful things in the house were collected by the trolls and used as decorations.

These human gadgets are much more delicate than the bones they polish!

The work of clearing the rubble of the building was so miserable for the trolls that it was enough to stuff all the trolls' houses and collapse, and the falling waste took the trolls five days to dispose of before they could clean it up.

They weren't very good at it, and their manpower was limited, and the other trolls had to continue building huts and walls, with only a dozen trolls and a few troll children clearing the rubble.

Darousa didn't pay much attention to clearing the ruins, as the leader of the Frost Troll Clan, all he had to do was keep himself in shape, and lead his men to victory and fruits when fighting or hunting.

Just as Darusa and several other masters of the Frost Troll Clan were training on the outskirts of the manor, a troll walked up quickly and interrupted them.

"Chief, we've found a hole in the ground under the human house!"

"Holes?"

Darusa looked puzzled, thought for a moment with his mostly muscular head, and then shook his head, deciding to go and see for himself.

Led by the trolls who reported the news, they walked through the remaining part of the uncleaned building debris, pushed aside a few trolls who were watching seriously, and saw the entrance to the cave that had been opened.

The cave in the ground is also the basement.

No trolls have dared to go in and check it out yet, and they are all waiting for the leader Darusa to decide.

When the troll wizard who was watching the bustle saw Darusa coming, he immediately said, "I have already probed with magic, and there is no normal life in it." ”

Normal life, of course, refers to creatures with flesh and blood that have not turned into zombie beasts.

Zombie beasts that can't be detected by spells looking for normal creatures are abnormal lifeforms.
