I can infinitely synthesize more advanced items

With a movement of Song Ping's body, he passed through the barriers of time and space.

There is an endless nothingness around the body, even a vacuum does not exist, and time and space are completely chaotic here.

Time and space are turbulent, and in the void, there are terrifying thought fluctuations criss-crossing here and there from time to time, making Song Ping shaken.

After nearly 1 minute, Song Ping returned to the Continent of the Gods.

This is the first time he did not pass through the gate of another world, but only used the space coordinates to travel between the two worlds.

Compared with shuttling through the gate of another world, directly crossing the turbulent flow of time and space consumes more time and consumes a lot of power.

Consuming time and more power is the next best thing.

With Song Ping's current strength, it is still a little bit reluctant to travel through the turbulent flow of time and space. If he hadn't kept the spatial coordinates of the Continent of Gods in his heart, he would have been lost in the turbulent flow of time and space and exiled in the endless void.

That is definitely more frightening than death.

Not to mention that there are many powerful alien demons in the turbulent time and space.

If not necessary, Song Ping decided to continue to use the gate of another world for a while, and wait until his strength became stronger, at least after he had full confidence, it would not be too late to travel through the void physically.

After returning to the Emerald City, Song Ping immediately issued an order to collect limestone from all over the world.

The development of the Internet has allowed the orders of the State Department to be quickly conveyed to all parts of the world in a short period of time.

And also thanks to the development of the Internet, the speed of knowledge dissemination has become unprecedentedly fast. Limestone, an important material in the construction industry, has begun to be used more and more important all over the world. Lime factories are constantly being established around the world. .

So it is naturally easier to collect.

After all, it was an order from Yanhuang Kingdom, and Yanhuang Kingdom didn't ask for it in vain, but bought it at a price higher than the market price.

If he behaves well, maybe he can get a favor from Yanhuang Kingdom, or at least get a good impression.

So the countries in the world are naturally very active.

Just over an hour later, replies came from all over the world one after another.

Send the collected quantity and the location to the State Affairs Office of Yanhuang State, and then the State Office will send the location coordinates to Song Ping.

Song Ping teleported there directly.

With Song Ping's ability, going to any place in the Continent of the Gods is just a thought.

This method greatly saves the time and manpower required for road transportation.

Song Ping kept collecting from place to place.

After spending more than an hour, Song Ping ran more than 400 collection points, and finally collected more than 42141417 kilograms of limestone.

The materials for synthesizing a sky-filling stone are enough.

(Directional Synthesis: Sky Mending Stone)
(Material fit: 75%)

(Material compatibility is higher, and the additional consumption is reduced by 1.5 times)
(Materials required: To synthesize a sky-replenishing stone, limestone*42141417 catties is required, and the lifespan consumes 470 billion years)
(Tip 1: Improve the purity of the item, or increase the grade of the material, which can improve the compatibility of the material)

(Reminder 2: The sky-filling stone is a special item, and the number of synthesis is determined by the consumable materials)

……

(Synthesized successfully)
(Heaven-replenishing stone: one of the ancient artifacts in the prehistoric world, refined by the Nuwa family, has the effect of bringing the dead back to life, repairing the incompleteness of the sky and the earth, and has infinite power. Note: There are 36501 pieces in total, and this sky-replenishing stone is only one of them , unable to play the true function of the ancient artifact, but still infinitely useful)
……

(Reminder: The number of synthesis times has reached the upgrade standard)

(whether to upgrade the system)
(Hint: upgrade requires 1000 billion years of lifespan)
Emerald City, the Chamber of Secrets in the Shrine.

A round stone exuding a hazy white light was suspended in front of Song Ping, only the size of a pebble, but exuding infinite mystery.

Because it was synthesized by Song Ping, this sky-replenishing stone has automatically recognized its owner, and has a close relationship with Song Ping.

Just synthesizing a sky-replenishing stone consumes a lot of resources.

Even with Song Ping's current ability, it is very difficult to synthesize a complete set of sky-replenishing stones.

Song Ping couldn't help being a little uncertain.

According to legend, Nuwa used [-] sky-patching stones to mend the sky.

I don't know if this one sky-replenishing stone is enough.

But in any case, since they are all synthesized, it is natural to try them first.

In addition to synthesizing the sky-replenishing stone, Song Ping was even more pleasantly surprised that after waiting for so long, the synthesis system could finally be upgraded again.

Along the way, the synthesis system has always been the root of Song Ping's ability to become so powerful.

(upgrade)
(Consumed 1000 billion years of life, upgraded successfully)

(Current system level: Level [-])

(Add new features: knowledge synthesis, directional search)

Song Ping got a lot of information from the system feedback.

In an instant, he understood the role of the two new functions.

Song Ping couldn't help but be overjoyed.

Knowledge synthesis, which allows him to synthesize book knowledge.

Although he was able to synthesize very powerful items before, he was still unable to synthesize books.

Song Ping once speculated that perhaps after the system is upgraded, the ability to synthesize books may be increased.

Now the system really did not disappoint him.

However, what makes Song Ping a little regretful is that although the new function of book synthesis is enabled, it is still subject to great restrictions.

It cannot be synthesized indefinitely.

Synthesis will be limited by the world Song Ping is currently in, and only knowledge that has existed in this world can be synthesized.

This is indeed a pity, otherwise, Song Ping would have synthesized a large amount of knowledge beyond Yanhuang Kingdom's current knowledge, allowing the Continent of the Gods to develop crazily at an explosive speed.

But now that it is restricted, this idea can only be given up.

Now the level of scientific and technological development of Yanhuang Kingdom has reached the most advanced level in the world. Relying on the current four-level synthesis ability, it is impossible to forcibly synthesize higher-level knowledge.

However, Song Ping only had some regrets.

The system has reached level four at present, but there is definitely room for further improvement, and the potential is still endless.

And another new feature, directional search.

This function is very practical, allowing Song Ping to collect synthetic items with the highest matching materials within the range of his divine sense.

And with Song Ping's current divine sense coverage, as far as the Mosa world is concerned, it can instantly cover the entire world.

The same goes for Evolution Continent and Gods Continent.

That is to say, in the future, Song Ping will no longer have to try various materials one by one to select items with a high degree of material fit, but can directly search the entire world through the system.

The upgrade of the system to level [-] was a pleasant surprise for Song Ping.

Taking the Sky-Bending Stone back to the other-dimensional space, Song Ping passed through the gate of another world, returned to the world of Mosa, and appeared on the street of a city.

Immediately, Song Ping's figure quickly blurred and disappeared.

Pedestrians came and went on the street, but none of them seemed to notice this scene.
