Among them, what Lin Yuan wanted to improve first was naturally the strength of Yuansha.

Lin Yuan let the amber button-shaped source sand on his sleeves turn into a vortex of flowing sand under his feet, and then threw one spiritual crystal after another into the vortex of flowing sand formed by the source sand.

The strength of the source sand also continues to increase with the consumption of spiritual energy crystals.

When Lin Yuan threw the 209th spiritual crystal into the flowing sand vortex, the source sand was successfully upgraded to the level of Diamond Level One Fantasy Second Transformation.

A stream of sand arose in the vortex of quicksand in front of Lin Yuan, and the sand flows intertwined in mid-air.

All of these sand flows are composed of guard sand, which is also the most flexible part of the source sand.

Lin Yuan looked and found that the guard sand had changed a lot at this time.

If the previous Kinwei Sand was just sand grains with clearer color, then the Kinwei Sand at this time has turned into almost transparent crystals.

These crystals have no color, but they seem to be able to contain any metallic spiritual material in time.

It is like putting metal spiritual materials into the Guardian Sand, and the Guardian Sand can obtain the characteristics of the metal spiritual materials by refining and extracting them.

Although the quicksand vortex did not expand outward under Lin Yuan's control, the downward force of the quicksand vortex was thousands of times greater than before.

The current vortex of quicksand can bury an ordinary diamond-level tenth-grade spiritual creature in just a few minutes.

After being promoted to the second level of Diamond Stage Fantasy, Source Sand still focuses on control ability, and its attack ability can only be regarded as a younger brother compared to the control ability.

However, if the life trapped in the sand sea sinks 300 meters underground, it will not be easy to survive under the huge high pressure from all directions.

What's more, there are killer moves brought by exclusive characteristics in the sand sea.

At this time, Yuansha had already made a request to Lin Yuan.

Request Lin Yuan to choose an exclusive characteristic and strengthen it.

Source Sand, as a special source item, is different from ordinary source items and spiritual objects.

After the source sand is upgraded to a higher rank, no new level will appear. Instead, you need to choose to strengthen any one of the exclusive characteristics of the gold-swallowing type and the sand and gravel spiritual absorption type.

This time, Lin Yuan did the same as last time and still gave up the exclusive characteristic of strengthening the source sand, which is the sand grains absorbing spiritual energy.

After choosing to upgrade the source sand from the gold level to the diamond level, the two opportunities to enhance the exclusive characteristics are all given to the exclusive characteristic of gold swallowing type.

One of these two opportunities Lin Yuan had increased the types of metals that could be swallowed by the Gold Swallowing Transformation.

One of the opportunities adds the exclusive feature of swallowing gold and transforming it into a certain shape.

At this point, the evolution of source sand has been completed.

However, Lin Yuan did not immediately strengthen other spiritual objects, but continued to issue commands to the source sand.

Let Yuansha spit out all the copper-grade metal spiritual material manganese and iron that it had previously swallowed.

Upon hearing Lin Yuan's instructions, neatly shaped ferromanganese continued to precipitate from the vortex of quicksand.

Lin Yuan collected the source sand as he spit it out. After a while, Lin Yuan had put all the manganese iron spit out by the source sand into a platinum-level soul-trapping box.

Although the metallic properties of ferromanganese are very suitable for source sand, as the rank of source sand increases, the opponents it faces become increasingly powerful.

The use of the copper-grade metal spiritual material ferromanganese is becoming less and less.

Therefore, allowing the source sand to devour manganese iron would be equivalent to wasting the types of metal spiritual materials that the source sand can devour due to its unique characteristic of devouring gold and transforming into a new shape.

Lin Yuan already had plans for the metallic spiritual materials that the source sand would devour after it advanced.

Prior to this, Lin Yuan had already prepared the metal spiritual materials that would transform into gold that would be needed for Yuansha to advance to the diamond stage.

One of them is radium-uranium steel.

In addition to being strong, radium-uranium steel is also very sharp.

When spiritual craftsmen are carving some metal spiritual materials, they often choose polished radium-uranium steel to make the blade of the carving knife.

Therefore, Lin Yuan thought it would be most appropriate to use radium-uranium steel instead of manganese iron to make a chain sword.

Although replacing ferromanganese with radium-uranium steel will make the source sand grains lose that file-like sharpness.

But the strength of radium-uranium steel also increases the strength of the sand, making it more difficult for objects trapped in the sand sea to break free.

As the types of metals swallowed by the source sand increase, the offensiveness of the entire sand sea can be enhanced by adding new metals.

Lin Yuan took out the platinum-grade metal spiritual material Red Lotus Soft Gold that he had asked Ting Ting to collect for more than a month.

Although Red Lotus Soft Gold is a platinum-grade metal spiritual material, it is definitely rarer than diamond-grade metal spiritual materials.

Because the platinum-grade metal spiritual material Red Lotus Soft Gold has only been found in level five underground dimension cracks, it is considered a specialty of level five underground dimension cracks.

In order to help Lin Yuan find the ten cubic meters of Red Lotus Soft Gold, Ling Ting spent almost all of the income from the sale of luxury goods by Ling Lu Chamber of Commerce.

There is no wrong version in the 1619 book forum!

When you hold a whole piece of Red Lotus Soft Gold in your hand, it looks like a ball of soft liquid metal with a red halo on it.

This liquid metal is somewhere between transparent and opaque.

As the soft red lotus gold changes shape, the red halo on the surface will flow rapidly.

The flowing halo is like a red lotus blooming on the soft red gold.

This is why Red Lotus Soft Gold got its name.

Although the Red Lotus Soft Gold seems harmless in its soft state, when the Red Lotus Soft Gold is stretched into filaments.

The red lotus soft gold infused with spiritual energy is the needle with the strongest piercing performance in the world.

After the source sand has swallowed up the red lotus soft gold through its exclusive gold-swallowing property, it can precipitate red lotus soft gold like silk threads in various parts of the sand sea at any time.

The silk-like red lotus soft gold that penetrates into the spiritual energy is the killer lurking in the sea of ​​sand.

In the absence of spiritual energy, the filaments of red lotus and soft gold intertwined together can also form a solid net that can be continuously extended.

Can cooperate with sand sea to attack or bind.

At the same time, Red Lotus Soft Gold is highly corrosive and toxic. When living things come into contact with Red Lotus Soft Gold.

Red Lotus Soft Gold will leave scarlet scars like red lotus on objects.

Red Lotus scars are essentially tiny rashes caused by the skin being contaminated by the toxins of Red Lotus Soft Gold.

The toxicity of Red Lotus Soft Gold will cause the target to lose their mind and become insane in severe pain.

The toxin also stimulates the tear glands, causing the target's eyes to shed tears uncontrollably and blurring vision.

Once this poison infects an enemy target, it is very likely to cause one of the enemy to go crazy and attack indiscriminately around.

When facing multiple enemies, it is like having an extra idiot teammate.

Watching that after the source sand swallowed a large amount of radium-uranium steel, it swallowed up ten cubic meters of the metal spiritual material red lotus soft gold.

Lin Yuan felt that the sand grains that had obtained some of the soft gold properties of the Red Lotus would cause anyone with a strong will to scream in pain if they stepped on them.

I would also shed inexplicable tears, as if I was crying out of fear.
