After I cultivated immortality, I discussed the theory of lifespan with a long-lived spirit.

Chapter 147 Five Spirit Swords, Cooperation Method

Lin Er carefully examined the descriptions of the two sword techniques. The Greatsword Technique was powerful and could supplement his attack methods.

The Five Elements Sword Formation has stronger overall capabilities and can also be used to set up a continuous sword formation. He is currently lacking a protective formation, so this is a perfect opportunity to use it.

However, this supernatural power actually requires five spirit swords. He went to great lengths to ask his mother-in-law, Yasna, to forge just one spirit sword, let alone five.

Not to mention the materials and moonstones needed for forging the sword, even spirit stones would be required—probably two or three thousand spirit stones. This prerequisite is simply too difficult to meet; it's impossible to do it now.

Seeing this, Lin Er was more inclined to use the Greatsword Technique, since he could use it right now.

At this moment, Illulian said, "If you choose the second swordsmanship, I can give you some enchanted swords as payment for your help last time."

"Sister, you don't need to be so polite."

Lin Er quickly waved his hand. He couldn't help but take another look at the detailed introduction of the Five Elements Sword Formation and found that it was possible to achieve the same effect without a spirit sword. Ordinary magic tools could also achieve the same effect, but the protective power would be weaker.

Something is better than nothing; the sword formation can be gradually strengthened later.

Of course, this is definitely not because Ilulian gave me the enchanted sword for free.

Lin Er then said, "Sister, I'll choose this sword technique. But I want to choose the attributes of the enchanted sword myself."

"That's no problem."

Ilulian readily agreed.

After Lin Er made his choice, a jade slip appeared in his hand. He didn't use it immediately, but instead said, "Sister, I'm going to see Elder Eliya. Could you help me show the way?"

"Alright, but what do you want with the elder?"

"Ilulian asked curiously."

"Let's make a deal."

Lin Er replied.

The two headed towards the tree fortress.

Lin Er encountered several elves along the way. Although they still greeted him, they were much colder than they had been a few days ago.

Lin Er felt much more at ease; otherwise, as before, the elves would have invited him to drink tea, and he would have found it hard to refuse their hospitality.

Ilulian explained in a low voice, "Everyone knows that you threatened the elders with the fertility magic stone to release Auntie from the dungeon, so that's why they did this."

Lin'er had repaired the fertility magic stone, and his reputation within the clan could have been even better. Ilulian sighed inwardly.

Lin Er suddenly asked, "Sister, do you also think I didn't do well?"

Ilulian paused for a moment, then slowly replied, "You are Flora's close friend, and I respect your decision."

Lin Er smiled slightly and said, "Sister, we've arrived."

Ilulian snapped out of her daze and quickly went to inform them before leading Lin'er into the tree fortress.

This time, Lin Er was quite familiar with the place and quickly met Elder Elia, who was sitting at the tea table, writing something.

After Lin'er entered the room, Elder Eliya slowly raised her head and said, "Lin'er, you use your teleportation spell quite frequently."

"This is all thanks to the teleportation ring the elder gave me."

Lin Er replied.

Elder Elia hesitated for a moment, then asked, "Are you still able to teleport? I'd like to ask you to help me purchase some things."

Although she also knows teleportation, it consumes a lot of magic power and cannot be accurately located, so she cannot use it at will.

Upon hearing this, Lin Er took out his magic pouch, from which he retrieved a stack of parchment pages, saying, "Elder, you should need these things, right? I brought them from Watchtower City."

After saying that, he took out many blank pages and some household items from inside.

Elijah's eyes lit up. Her clan could also make these things, but it would take a lot of time, especially the parchment.

Trading with other tribes in the Elf Forest requires precious magical materials, which are not worthwhile in some cases. Therefore, the most cost-effective way is to purchase them from human settlements.

However, since we are currently in a period of tidal fluctuations and it is not easy to go out, this matter has been put on hold.

Elijah's expression also turned somewhat strange. She had only learned two days ago that the warehouse was short of supplies, and Lin Er's arrival just happened to bring the lacking supplies. What a coincidence!

Seeing Elder Elia's expression, Lin Er explained, "Flora told me about this before I left last time, so I brought some with me when I came back."

"That child is quite thoughtful," Elijah couldn't help but smile, and continued, "What do you want to exchange?"

"Inferior magic stones," Lin Er replied, adding, "I wonder how much these can be exchanged for."

Elijah immediately had Ilulian come over to take inventory. The supplies purchased this time were not many, costing only a little over two hundred coins, with parchment being the largest expense.

After Ilulian finished counting, Elder Elia nodded and said, "These things are going up in price now, so I won't take advantage of you. How about four thousand low-quality magic stones in total?"

This price exceeded Lin Er's expectations and was much more cost-effective than acquiring it in Watchtower City.

Lin Er nodded and said, "It was just a small favor. If the elder wants more, I can bring some more next time."

"Thank you, this is more than enough." Elder Eliya waved her hand and said, "Judging from your expression, you still want to trade inferior magic stones?"

"Yes." Lin Er nodded and asked, "What does the elder want to purchase? If I can do it, I will definitely not refuse."

Elijah looked up at Lin Er and shook her head.

"Our clan only needs mature magical plants now, such as Galegrass, but I guess it's not easy for you to get them in Watchtower City, since Galegrass is usually very expensive."

"Is this for Sister Ilullian and Flora?"

Lin Er asked.

Flora had searched for this magical plant before when she was in the Misty Forest.

Elijah nodded and said, "You seem quite concerned about those sisters. Many elves in our clan need this magical plant. Although Galegrass grows quickly and we've planted quite a bit, the quantity is still not enough."

Lin Er fell into deep thought. He remembered that spiritual energy had a ripening effect on magical plants, and if he planted a batch near the spirit-gathering array, the effect should be quite good.

Since the Spirit Gathering Array cannot absorb wind elements, a large amount of wind elements will accumulate nearby. Now that we have the Gale Grass, it won't be wasted.

"Elder, if I provide a batch of Gale Grass, what price are you willing to offer?"

"You want low-quality magic stones, right? I can offer at least a thousand low-quality magic stones for a mature Galegrass. If it's of good quality, I can raise the price."

A single Gale Grass can sell for one hundred spirit stones; such a price is simply irresistible.

"Elder, it's settled then." Lin Er suddenly remembered something, paused, and said awkwardly, "Elder, I wonder if you could provide me with some Gale Grass seeds?"

Elijah asked doubtfully, "Are you planning to plant them near Watchtower City? These seeds need to be planted in a place rich in elemental power, and it will take at least six months for them to begin to grow."

"I'm going to trade the seeds for it."

Lin Er replied.

"OK."

Elijah immediately gave Lin Er a seed bag containing ten Galegrass seeds.

She then added, "I'm not giving these seeds away for free; I want to ask you a favor."

"Please speak, Elder."

Lin Er immediately perked up his ears.

Elia glanced at Ilulian and waved to her.

Illusion understood perfectly and withdrew voluntarily.

After seeing her leave, Elia continued, "Lin'er, when you return to Watchtower this time, I'd like you to take Ilulian with you."
