On February 16, 1176, after several days of trekking through mountains and rivers, Yan Tielong and the others finally arrived at the Thunder Lion mercenary stronghold yesterday.

Facing Yan Tielong's team of tens of thousands, Yan Luo Lei Shi was very curious about how much he earned last time? This time, the number of people almost doubled.

Of course, Yan Tielong did not tell the second brother how much money he made truthfully, but the profit value that Yan Tielong told also made Yan Luo Lei Shi very envious.

However, Yan Luo Lei Shi began to worry that Yan Tielong would choose to run the business, regardless of the development of the stronghold, after all, the base that Yan Tielong wanted was still occupied by a large group of green skins, and the profits of the running business were very attractive even to Yan Luo Lei Lion.

Yan Tielong faced the worries of the second brother of Jieyi, and he said that he would focus on developing the stronghold after running the business this time.

Of course, in order to convince the second brother of Jieyi, Yan Tielong took a hundred dark elf girls to the stronghold to deal with the green skins in the stronghold.

At half past nine, Yan Tielong and nearly 100 of them came to the stronghold circled on the map.

Looking down from the top of the hill to a stronghold still occupied by the Greenskins, Sicilia made it clear that this area was indeed a good location for a future town, but also pointed out that there was no terrain barrier in such a place, and the future city would be easy to attack and difficult to defend.

Yan Tielong agrees with Sicilia's evaluation, after all, this area is a rare plain in the green road, and there is no favorable terrain around it as a barrier.

The other mercenary groups are all looking for mines, while mining, while creating fortifications, just like the stronghold of the Thunder Lion Mercenary Group, there is only one exit, and the others are covered by mountains, so it is easy to defend and difficult to attack, even if millions of green skins cannot be attacked, but the weakness is that it is easy to be surrounded to death, so the Thunder Lion Mercenary Group will dig tunnels just in case.

As for the lack of a defensive barrier, Yan Tielong said that he could just build a barrier by himself.

When the Yanluo Lei Lion who came from the side heard that Yan Tielong wanted to make a barrier, he was curious about how to make a barrier, you must know that it costs a lot of money to build a barrier in the plain, after all, this is a green-skinned continent that is easy to be attacked by greenskins.

Yan Tielong didn't say anything, but led everyone down the mountain to the plain to start cleaning up the green skin, and soon cleared a blank area, and then Yan Tielong and the dark elf girl carried the seeds from the carriage and began to plant.

Seeing that Yan Tielong was busy planting, he didn't know what Yan Tielong was planting, but he said that what Yan Tielong planted would become the rations of the green skin.

Hearing the reminder of the second brother, Yan Tielong asked the dark elf girl on the side to make a demonstration.

A girl from the dark elf clan on the side heard Yan Tielong's story, she threw a seed at the green skin that was close to them, and when the seed touched the ground, the seed quickly grew into a devouring grass, and the devouring grass swallowed the green skin around her.

Seeing that the devouring grass that had grown eight like man-eating flower heads continued to devour the green skin, the Yanluo Lei Lion asked Yan Tielong on the side, would the plant attack indiscriminately?

Yan Tielong said that devouring grass would indeed attack indiscriminately for them, but the dark elf clan had a way to control those devouring grasses, and also said that swallowing grass alone could not block the green skin, so he also planted other poisonous plants as subsidies, and when it was completed, he would build a wall to isolate these dangerous plant areas, so that there would be artificial natural hazards.

After listening to Yan Tielong's plans for the future, Yan Luo Lei Shi raised a concern, which was that someone would set fire to plants in the future, and when the time came, it would be a fire that burned the man-made barrier.

As for Yan Luo Lei Lion's worries, Sicilia, who followed Yan Tielong, replied that these seeds were the continuous research results of their dark elves, and they lived underground, and some places were close to the ground flames, so they had already studied plants that could withstand fire and even absorb flames.

Some people may ask why the dark elves don't plant the underworld after they want to grow fire-absorbing plants and fire-resistant plants, so that there is no need to be afraid of any Earth Flame Demons.

In fact, the dark elves are not without consideration, but these plants have a fatal flaw, this disadvantage is that they like sunlight, if they don't have enough sunlight, they will die quickly, and only a small natural city in the bottom world can keep these plants alive.

One might think that the Dwarven Mirror City does not use the principle of mirror refraction to shine the sunlight from the surface into the ground, and the elves cannot have this method.

Of course, both the dark elves and the fallen elves have thought of this method, but the refraction method of Jingyang City is actually a method with a very high maintenance cost, generally speaking, it is close to the surface, but in this way, the cold on the surface will make the elves and plants unbearable, after all, the elves don't want the dwarves to use wine and fire to drive away the cold.

Of course, Yan Tielong didn't know at this time, after he learned that all the plants he and the dark elf girls planted were frozen to death, they naturally cultivated cold-resistant and fire-resistant varieties, but these are all later words.

Watching the dark elf girls use natural magic and potions to spawn various plants to form barriers, Yan Tielong and the others didn't just watch, they kept killing the green skins that broke into the dangerous range.

It was noon soon, and the dark elf girls' magic power and potions were consumed, but they also planted a plant defense barrier of three hundred square meters.

While the Dark Elf Girl was enjoying lunch, Yan Tielong found a Green-skinned Horned Beast Leader and several thousand greenskins through Xiao Yin, and he wanted to try to see if the plant barrier could block the Green-skinned Horntooth Beast Leader.

Of course, Yan Tielong was also worried that too much greenskin would destroy the three-hundred-square-meter plant barrier, so Yan Tielong led a green-skinned horned tooth beast leader and a hundred green-skinned horned tooth beasts.

Since Yan Tielong was first coated with a special scent potion by the dark elf girls, this also allowed Yan Tielong to enter the plant barrier that had just been formed and not be attacked by plants, but chasing Yan Tielong's green skin was not so good, when they entered the plant area ten meters, the vines in the plant area actually took the initiative to attack.

Soon more than a dozen green-skinned corneas were killed by the vines, and the remaining greenskins entered the plant barrier, at this time a large number of plants launched an attack on the greenskins, and soon most of the greenskinned corneas were solved by the plants, but only the greenskinned horned tooth beast commander continued to attack the surrounding plants as if nothing happened.

Yan Tielong, who had already arrived in the safety zone, asked Sixilia beside him, those plants could really solve the Green-skinned Horntooth Beast Leader, after all, even his Black Dragon Blade had to charge up to break the Green-skinned Horntooth Beast's Leader Bone Armor.

Hearing Yan Tielong's inquiry, Sicilia was very confident that vines and grass devouring grass alone could not harm the Green-skinned Horntooth Leader, but the Phantom Eater and the parasitic dandelion in the plant area could solve the Green-skinned Horntooth Leader.

After listening to Sisilia's story, Yan Tielong saw that the green-skinned horned beast leader was constantly glued to the parasitic dandelion like white cotton, and Yan Tielong also found that the green-skinned horned beast leader's movements were slowing down.

When the dark elf girl finished eating the food, the green-skinned horned beast leader continued to cut down the surrounding vines, and the three hundred square meters of plant barrier was also cut down.

Finally, I saw the Green-skinned Horned Beast Leader fall to the ground with all his strength, and those dark elf girls rushed to the Green-skinned Horntooth Leader who fell to the ground.

Seeing those dark elves in action, Yan Tielong was a little worried that those dark elf sisters would also be parasitic dandelions.

However, Yan Tielong quickly thought that all those plants were planted by those dark elf sisters, and thought that they had a way to deal with those plants.

And just as Yan Tielong thought, Sicilia told Yan Tielong that those parasitic dandelion seeds that have turned green have been filled with energy, and the energy of the green parasitic dandelion seeds is injected into those dying plants, then those plant injuries will quickly recover and strengthen the plants.

At the same time, Sicilia sighed and said that if the dark elves could master the purple elves' parasitic dandelion seed potion technique, they would be able to make an amethyst universal recovery potion suitable for creatures.

Through the system, Yan Tielong understood that the Amethyst Universal Recovery Elixir is powerful, and the Amethyst Universal Recovery Elixir can restore 10% of its own physical strength, magic power, and fighting energy, and at the same time, it will continue to recover 1% and detoxify and detoxify the curse every second for ten minutes, and the most important thing is that there are no side effects.

Originally, Yan Tielong wanted to learn to make an amethyst universal elixir, but the system told Yan Tielong that even if Yan Tielong mastered the formula of the amethyst universal elixir, he could not make it, and having an amethyst universal elixir required the special ability of the purple gold elf clan to make it, which means that the amethyst universal recovery elixir is an exclusive elixir for the purple elves.

Yan Tielong still found a lot of parasitic dandelion elixirs from the system, but the effect was incomparable to the amethyst universal recovery elixir, and those elixirs with parasitic dandelion as the main ingredient only had two effects at most.

Seeing those parasitic dandelion formulas in the system, Yan Tielong couldn't help but spend a lot of points to change, after all, Yan Tielong thought that there would be no shortage of parasitic dandelion seeds as a raw material in the future.

Yan Tielong, who had recovered from the system, asked Cicilia for some parasitic dandelion seeds that had been full of energy, and he wanted to do some experiments.

For Yan Tielong's begging for the parasitic dandelion that had been full of energy, Sicilia was very generous, and she asked the sisters she collected to get a trace for Yan Tielong.
