Returning to the stone chair, Lin Dong took out a stack of papers, which recorded his future arrangements for himself.

In his contemplation, he didn't notice that it was already dark outside, and a little hazy moonlight shone on his face, casting a silver glow on his face.

From the time he came to this world to the present, his cultivation has reached the ninth level, and his physical cultivation has also reached the peak of the first order, which is related to the too many spirit stones he has obtained.

Now his cultivation is still low, but his consumption is no less than that of a cultivator in the foundation building stage who has been promoted to the Jindan stage. One day he built a foundation, and he wanted to ascend to the golden pill, and the spirit stones needed were even more astronomical.

If he wants to ascend to Yuanying, he will cultivate his qi and determine that character, and the spirit stones needed alone will exhaust him. How to have a stable source of spirit stones has become the most important problem for him to solve now.

The Dongling shop is too small, and the innate restrictions make the Dongling shop not bring him enough spirit stones.

It seems that the only way to do this is to take the road of invention and creation. Lin Dong thought that when he first came, he had a plan to rely on the knowledge of his previous life to earn spirit stones, but because his strength was too weak and he didn't have a good direction, he could only keep it in his heart.

Now that he is a character on the battlefield, and with the care of Bu Hongchen, the Jindan period, he can be regarded as able to protect himself in terms of safety.

In addition, Mo Yu seems to have a lot of energy in Duobao Pavilion, so some things can be released through the channel of Duobao Pavilion.

If you want to do a big, long-term business, he now has the conditions to start, it depends on the meaning of Mo Yu and the Duobao Pavilion he represents.

"Qiu Xiao went to inform today, Mo Yu should be able to arrive tomorrow. I'll go get ready first. Lin Dong got up, and the small door at the back of the hall came to the refining room.

Behind the hall is a large open space, and beyond the cliff is a row of houses made of black stones.

There are ten rooms in the house, all of the same style, without windows, and only one door with a carved formation.

Each room has its own function, there are alchemists, there are refining tools, and there are cultivation rooms.

Lin Dong first opened the protective formation at the top of the peak in the clearing, and the black control jade slip sent out a black line under the impetus of mana, shooting straight at the center point of the formation on the ground. A yellowish mask protects the entire summit from within.

Looking left and right, this earth formation was a third-order, and it was able to block the three full-strength attacks of the Jindan cultivators, and he was very satisfied. What's even more satisfying is that this formation doesn't need spirit stones, as long as the high-level spirit veins under the East Spirit Peak are not exhausted, they can be maintained indefinitely.

The third room on the left hand is where the refining room is located, which has an earth fire vent and a first-order high-grade refining furnace that is a head above him.

These are free, standard for elite teams. Even the cave mansions of those team members at the peak waist are all the same configuration, but they are a little smaller.

Unlike when Lin Dong was in the Demon Slaying Domain, he had to go to a special place to refine a pill, and most importantly, he had to pay spirit stones.

I tried the earth fire first, and the high-grade earth fire is different, the fire color is pure white, and the temperature is extremely high. I sensed it with my spiritual sense, and there were very few impurities, and it was very stable.

Lin Dong had never done it before, and now of course he didn't want to refine any earth-shattering treasures.

He took out a few pieces of paper from the ring, and these were the three things he had designed.

The first sheet of paper is a barrel with two discs, in the form of a three-view used by a technician in the previous life. It is marked with dense numbers and various explanations. The annotation is written in Chinese with Arabic numerals, and in this world, only he understands what he writes.

This is a drawing of a telescope, and the limit of his telescope is that he can clearly see the faces of people two miles away. It's not that he doesn't have the ability to look further, it's that he is the customer of this telescope, and he is facing those first-order cultivators at the bottom of the immortal cultivation realm who have the most.

For a first-order cultivator, as long as he can see the movements within two miles, it is enough to hunt demon beasts or follow others.

After reading one and reading the next two, check the data for errors.

The other two are designed for physical cultivation, one is a bow and arrow, which is used for medium and short-range attacks. The other one is the bed crossbow, which is used for ranged attacks.

There are no two things in this world, why doesn't he know. However, these two things can make up for the lack of physical cultivation in the first order of long-range and medium-range attacks.

And on this battlefield of the three clans, if the physical cultivation has these two things, it is almost an insoluble existence.

Think of the all-metal crossbow arrows that are three feet long and arm thick, and if they are shot out in rows of marks, the scene is truly intoxicating.

The idea is good, but it is difficult to implement.

These body cultivators are all strong men, all of them have the strength of nearly a thousand catties, and this bow and arrow and bed crossbow should be designed to fit them and maximize their strength.

How much strength do modern talents have? One or two hundred is considered to be a great strength.

The design is a little difficult, the volume is much larger, and the more difficult thing is the material problem. This is a high-energy world, and it has a unique way of refining. How to combine the advantages of the two worlds and make a long-term thing is what Lin Dong wants most.

Now he doesn't know anything about refining weapons, and he can only temporarily supplement the relevant knowledge.

Fortunately, it's just a sample, and it has enough power to impress Duobao Pavilion.

After a brief look at the refining foundation, the first few steps were similar to the iron-making in the previous life.

Lin Dong patted his head, "That is, refining the ore, then refining and plasticizing it, and then there will be a formation." ”

You don't need a formation or anything, that's what Duobao Pavilion will worry about in the future, and now there are the first three steps.

A piece of ore the size of a table top was thrown into the refining furnace, and Lin Dong clapped his hands, "Start work." ”

A raging fire rose into the sky, scorching flames scorching at the bottom of the furnace.

Seeing that the refining furnace had reached the temperature, Lin Dongfa made a decisive move, and one by one illusory runes came out of his hand and submerged into the refining furnace.

The streaks on the furnace began to glow, and all the earth fire was sucked in by the array, and then burst out of the furnace mouth with a bang.

The pillar of fire flew directly onto the roof, separated from the middle under the effect of the roof formation, forming a fire curtain and returning to the furnace.

The fire curtain emitted a dazzling white light, causing Lin Dong's eyes to narrow slightly. At the same time, the high temperature seems to ignite the air in the room, and if you take a breath, it is like inhaling a fire.

The ore melts rapidly at high temperatures, eventually forming a furnace of blinding liquid with no visible color.

The law duel was struck again, and the furnace body shook, and all the liquid floated above the furnace. Accept the burning of the fire.

Lin Dong's hand movements became faster and faster, forming a hazy light and shadow. The resulting runes flew into the furnace like dense butterflies.

Now it is the refining stage, and the impurities in the liquid need to be removed as much as possible in a very short time.

The liquid begins to spin at a faster and faster speed. Some black impurities are constantly thrown out.

The speed of rotation reached a limit, and Lin Dong pushed his hands forward. The furnace fire quickly changed from white to transparent, and then it all retracted into the furnace.

A swirling mass of metallic liquid stood out of thin air.

Wiping the sweat from his forehead, the temperature here is too high.

The step of shaping is a lot easier, there is no way, spiritual sense and object exploration are the basic skills of cultivators.

With a movement of the psychic sense, a mass of liquid was separated. Then the liquid begins to stretch, deform.

Soon a cylinder appeared in front of Lin Dong.

The cylinder is still a little warm. I took it in front of my eyes and looked inside and out,

The control of the psychic sense was very precise, and according to his eyes, the surface of the cylinder, which was thick at the front and thin at the back, had a smooth surface and a graceful arc. No worse than the accuracy made with a machine tool.

Set this cylinder aside. Lin Dong made another bow and ten bows and arrows.
