After descending from the airport wharf, Lu Chengfeng walked about three kilometers of road, and then smoothly entered Kaiyang City.

As the capital of the Lanwu Empire, the prosperity of Kaiyang naturally does not need to be mentioned. Even though Lu Chengfeng had experienced the heyday of Chaoge City back then, and seeing the current Kaiyang, he couldn't help but spend half a day walking around. After appreciating the customs of the Western Continent, he found the Alchemy Union according to the instructions.

In addition to the headquarters of the All-Continent Alchemist Association located in the Tian Yuan Empire, the Alchemy Guild of the Lanwu Empire was already the top-ranked alchemist organization in the western part of the continent. There are many talented people here, and there are no less than five pharmacists who are qualified to be called grandmasters. There are all kinds of magic potions, and even the most knowledgeable magician may not be able to break them in one bite.

Lu Chengfeng only walked around the exhibition hall of the Alchemy Guild and saw thousands of potions. These potions are so beautiful that they have different effects: they can speed up wound healing, help Dou Qi progress, apply specific curses, and even have the ultimate potion that instantly restores all of Dou Qi - the source of power!

Just such a small bottle of dark blue potion, the price tag is as high as six million gold coins.

At this price, even the prince of the empire back then couldn't help but smack his lips when he saw it. With 60,000 gold coins in his hand, he couldn't even buy a drop of this bottle of power. Fortunately, he was very self-aware, and after stopping and looking at it twice, he quickly left, and began to choose the potions that he could really use.

Qi Gathering Pill!

This is a potion that can speed up the cultivation of Dou Qi, which is just right for Lu Chengfeng at the moment. As early as 1,200 years ago, its formula was already very mature. Although the effect is not too significant, the price is 400 gold coins per bottle, but it has one of the biggest advantages, that is, the effect is mild, and the side effects are very small. Even if it is taken continuously, it will not develop resistance, and it will not leave any hidden dangers.

Taking into account his financial resources and rank, the Qi Gathering Pill is actually the best choice.

The best effect of this potion is to take five bottles per month. In this way, it is 2,000 gold a month. In line with the idea of being prepared, Lu Chengfeng generously threw away a year's order and directly spent 24,000 gold coins. Coupled with some other commonly used medicines purchased, Lu Chengfeng spent a total of 30,000 yuan!

The 60,000 gold coins that had just arrived were half less in a blink of an eye.

As a former prince, Lu Chengfeng obviously has no psychological barriers to spending money. A large amount of gold coins were scattered in exchange for an accelerated increase in strength, which was very necessary for him now. After all, the strength of the third order was too low, so that he who was once quasi-ninth order did not have the slightest sense of security.

After completing the initial purchase, Lu Chengfeng found an inn to live in. One is to settle down temporarily, and the other is to prepare to consider the matter of forging lightsabers.

It's not easy to forge a lightsaber.

A qualified lightsaber is generally composed of three main parts: first, the elemental gem/magic core that can store energy and withstand the impact of the enemy's fighting energy, second, there must be a continuous excitation circuit, and third, there must be materials that can stabilize the accumulation and withstand light energy. All three are indispensable.

Continuous excitation circuit, this Lu Chengfeng is not worried.

As a former lightsaber royalty, he has enough classic circuit designs in his head. All he needed to do was find a craftsman who could forge it, and he could take out the excitation circuit.

The real difficulty is the energy storage gems and the materials that concentrate light energy.

Without the former, there would be no lightsabers. Without the latter, the energies excited will quickly escape. If the materials of these two materials do not meet the requirements, the forged lightsaber will be greatly less powerful, or the energy consumption will be greatly increased. It may be that before a battle is over, the lightsaber is already dim and unusable.

The reason why the lightsaber genre will be obliterated by history is largely related to the demanding materials for forging.

An energy storage gem, even if it is only suitable for the most ordinary third-order lightsaber, will cost at least five or six thousand gold after processing. Demon cores are cheaper, but the energy purity in most magic cores is not high, and the energy they can hold is limited. Therefore, unless it is particularly suitable, it is still the first choice of energy storage gemstones. Since Lu Chengfeng was forging a lightsaber for himself, he must have gone straight to the best lightsaber that a third-order swordsman could get. In this case, just for the storage of gems, he would be prepared to spend one or two thousand gold!

In addition, materials suitable for accumulating light energy are also extremely expensive.

If you count the cost of other auxiliary materials and the forging itself, such a lightsaber will cost at least thirty or forty thousand gold coins!

The cost is too great.

Compared to this price, in the Suo Lan Workshop, which represents the highest smelting technique in the mainland, it only costs 3,000 gold coins to buy a good Taidao. If it's 5,000 gold coins, you can get a qualified greatsword. If you spend 10,000 gold coins, you can even customize a sophisticated weapon with magic amplification!

Knowing this price comparison, it is not difficult to explain why the lightsaber once withdrew from history.

Moreover, what makes Lu Chengfeng even more troublesome is that it is not 1,200 years ago now. At the moment when the lightsaber school is declining, even if he clearly knows the process and method of lightsaber forging, which blacksmith has the ability to succeed and forge it for him at one time?

After thinking about it for a long time, Lu Chengfeng didn't come up with any brilliant ideas, so he could only practice it and come step by step.

Materials that accumulate light energy can be collected by yourself. Energy Storage Gems, which can be purchased through the Auction House or the Mercenary Guild. As for the master who can forge a lightsaber, this can only be contacted by Lu Chengfeng himself. If it really doesn't work, after preparing the materials, Lu Chengfeng will leave for the Suo Lan workshop in the Northern Barbarian Territory. Although it was far away from the Lanwu Empire, he would definitely be able to find a top-level blacksmith grandmaster there.

With this decision, Lu Chengfeng found that he needed to stay in Kaiyang for a while.

For this city, which was built after the fall of the Tianfeng Empire, Lu Chengfeng did not have any special feelings. The fragments of memory are only a few transactions with the Truman Chamber of Commerce. But judging from the current situation, it is necessary for Lu Chengfeng to stay here for a while.

Although his predecessor was the little baron of Tian Yuan, he had no fiefdom and no reason, and he had nothing to do when he went back. Here, Kaiyang is the top city in mainland China, with a population of millions. Even if the city lord of Changyuan City wanted to send someone to deal with him, he didn't know how much effort it would take to find his traces.

After his fighting spirit was promoted to the fourth order and the lightsaber was in his hands, Lu Chengfeng no longer needed to be afraid of the black wolf bandits and the subordinates of the city lord of Changyuan City.

In the next two days, Lu Chengfeng began to frequent the mercenary union and taverns in Kaiyang. Here, he can get a lot of information and get a clearer picture of the world 1200 years later. At the same time, he can also learn about the distribution and production of nearby monsters, and take the opportunity to issue a task to purchase high-quality energy storage gems. With a two-pronged approach, Lu Chengfeng soon discovered a good material - the bone meal of the fluorescent cat demon.

This material, produced from the third-order demonic beast fluorescent cat demon, is often found in the endless forest on the west side of Kaiyang.

The bone meal of the fluorescent cat demon has good performance, which can effectively gather the energy excited by the lightsaber. Moreover, the fur of the fluorescent cat demon itself is also very popular, and the mercenary guild has the task of buying a large amount of money. Ten whole furs, worth a thousand gold coins!

Although Lu Chengfeng still has 30,000 gold coins on his body now, he can squander them for a while, but it is obviously not a long-term solution to sit and eat empty. If you do it easily, it is still very cost-effective to have 1,000 gold coins in your account.

It looks like a good plan, but the gathering place of the fluorescent cat demon is in the Endless Forest, which is not a safe place. A large number of short, tan-skinned kobolds haunt it. This gregarious monster with a cowardly and brutal tendency will often launch insidious attacks on outsiders in hordes. Around there, there were tribes of minotaurs who had been driven from the defense line of Lunyu Pass in the south.

Those big guys with strong physiques who were strong enough to compete with a fourth-order swordsman with their physical strength alone were enough to make any third-order swordsman despair.

Even some adventurers who form a team may not return if they are not careful.

For the possible risks of this trip, Lu Chengfeng has also made sufficient preparations. After spending fifty gold coins to buy a detailed map and the distribution of the Minotaur tribes, he picked up his freshly repaired sword and walked out of the west gate of Kaiyang in an ordinary caravan.

From here, continue thirty kilometers west and you'll find the Endless Forest.

No one knows the size of this vast forest. Danger and wealth coexist in it, there are countless terrifying fourth-order and fifth-order demonic beasts, and they can produce all kinds of rich resources. What's more, legend has it that in the deepest part of the forest, there is a kingdom abandoned by the Spirit people during the Blood Moon Catastrophe. After the forest fire ten years ago, the last group of guardians of the Spirit Clan also disappeared, and the remnants of the Spirit Clan have become uninhabited ruins.

From then until now, countless swordsmen like Lu Chengfeng have ventured into the forest, hoping to make discoveries.

Although ninety percent of adventurers fail, there are occasional adventurers who find something valuable and get rich overnight. Under their stimulus, such exploration has not stopped since ten years ago. Those businessmen who met by chance, only when Lu Chengfeng was also one of them, didn't think much about it at all.

In fact, Lu Chengfeng was just borrowing them to cover up his tracks. As they approached the Endless Forest, the two sides parted ways.

The endless forest in summer is rainy, and there is a faint smell of decay in the air. The thick fallen leaves and unknown moss on the ground are full of water, and they are one foot deep and one foot shallow, and they make a fluttering sound when they walk up.

This terrain gives Lu Chengfeng a familiar feeling.
