Three days later, February 12.

White light like a sword, cutting through the night.

It's dawning.

Hong Fan woke up from his stupor.

The warmth brought by Pei Yuan Dan and the cold feeling of Jiao meat still remain in the nerves.

After a few nights of penance, he was already familiar with the strange veins of true qi.

With the help of two precious resources, the cultivation speed increased to four months.

It's just that this high speed is not sustainable.

The two Pei Yuan Dan and half a catty of Jiao meat given by Hong Li are only enough for ordinary people to use for half a month.

In the Yanliu Gongsha world, Hong Fan forced a bowl of water to be flat, and he had to give a five-fold discount.

Yesterday, he went to consult Qiude, and learned that the cost of this little thing was about a hundred taels of silver.

That is to say, the full efficiency is full, ordinary people need 2,400 taels a year, and Hong Fan himself needs 4,800 taels.

It's outrageous.

Even if the clan is willing to pay this money, Hong Pan, who is far away in Xijing, may not have the channels to collect enough goods.

Outside the window, the rooster sang for the third time.

The orange-red morning light illuminated the window lattice.

Hong Fan sat down, picked up a thread book from the bedside, and turned to the pages of the book in his memory.

In addition to practicing martial arts, he borrowed a lot of books from the instrumental supervisor, most of which were idle books and miscellaneous conversations.

But in these books, there is the outline of Dahua.

After the human race was protected by the ancestral dragon, it multiplied and lived in the current Dahua Dynasty, with a population of more than 100 million.

Considering that the household registration census of the imperial court is lagging behind and extensive, counting the hidden households and slaves, it is not too much to add tens of millions of the actual population.

With this population, coupled with the prevalence of martial arts, the number of martial artists is naturally very large.

In the official propaganda caliber of the Zhangwu Academy, Dahua claims to have a million penetrating martial artists, and its hard power exceeds that of any alien race in the Eight Desolations.

However, the situation is very different.

According to Wen Zhongguan, including the three major vassal states, the total number of warriors and above will never reach 100,000.

In other words, even if Hong Fan's cultivation is not one in a thousand, at least it is one in a thousand.

When you reach this cultivation, you can be prosperous in any city and county, and you also have the basic ability to protect yourself.

Half of the book was finished, and it was already dawn.

Hong Fan changed his clothes, hastily had breakfast, and went straight to the southeast gate.

The spring cold is not yet gone.

The wind blew intermittently, like a cold hand on the face.

Hong Fan hadn't been out of the city for a long time.

No chaperones, no carriages.

He hiked alone with a hood on his head, and met Taishan for the first time after the beginning of spring.

There are still scattered remnants of snow on the top of the mountain, like a simple jacket.

But from the mountainside down, it has been covered with a long skirt that makes people feel happy at a glance.

In the uninhabited col, Hong Fan found a low tree that did not fit in and began to practice the new killing method.

Fire Cloud Palm.

Yan Liujin ran under the urging of his will, gathered in the palm of his hand along the three yang meridians, and then turned into invisible fire energy, surging out.

Ten meters away, the branches and leaves of the dwarf trees were scattered in the sky, and they were burned into charcoal before they hit the ground.

On the front of the trunk, the bark burns and crackles.

Just like the soldering iron hand, the killing methods that Yanliugong is matched with are not difficult to learn, it is nothing more than luck gathering, release from the body, and so on.

But the real effort lies in temperature and speed.

Like when Hong Sheng faced off against Gong Pengyun, he turned his hand and blasted out of the fire cloud palm in the strong confrontation, Hong Fan was far from being able to do it.

After half an hour of practicing the Flame Flow Killing Method, it was the turn of the Sand World.

A month and a half has passed, and Hong Fan's focus on the same three topics:

Sand Mayfly V1.3;

Scorching Sand V0.8;

Power Glider V1.7.

It's just that the progress has changed from "feasibility study" to "optimization experiment".

Among the various applications of sand flow, the sand mayfly was one of the first killer moves that Hong Fan realized.

And the first two lives he captured after crossing over—the two wolf greens that Jiang Youcai was in charge of—died under the simplified version of this trick.

Imagine, within tens of meters around Hong Fan's body, the sand and fog are rolling and scattering.

Whenever an enemy enters, whether it is long scales or heavy armor, it will be pursued by an endless and pervasive stream of sand, clogging the five orifices and eroding the internal organs.

If this move is successful, not only is it almost invincible in the same realm, but it can also quickly kill or subdue a large number of enemies with a low true element consumption, which can be called a battlefield harvester.

According to Hong Fan's own estimates, if the complete body sand mayfly is included in the "Musashi" of the Zhangwu Academy, even if it does not enter the first grade, at least it is a second grade ceiling.

However, the ideal is beautiful, but the practice is difficult.

Sand fog and sand arrows are very mechanical and simple ways to kill.

For example, if you use a firearm and pull the trigger to let the bullet come out, you don't have to worry about the aftermath.

But sand mayflies are different.

It requires Hong Fan to maintain sensory locking and channel the sand flow, and to shoot at multiple targets, the required concentration is multiplied.

In addition, the speed and strength of the sand should not be slightly weaker.

When the Nine Paths are cultivated, Hong Fan's effective killing range is only three meters, and once this distance is exceeded, the fine operation will inevitably be deformed.

And now he is in the same vein, and within six meters, he can make the barren sand gather and scatter at will, like an arm.

In the shallow forest with shrubs, the wind and sand storms.

Eight newly caught mountain rats were released and rushed towards the outer wolves.

Then a stream of sand suddenly coalesced, dragging them back to the Juggernaut's feet.

Half an hour later, the sand fog cleared.

Hong Beom gasped.

The poor rats were on their bellies, their limbs still twitching.

Thoughtfully changing the training ground, Hong Fan started the next project.

Compared with the sand mayfly, the research and development progress of scorching sand is even lower.

The envisioned image should be a high-temperature sandstorm swept by the wave of the hand, sifting the enemy's flesh and skin and draining the blood.

Without a fully enclosed three-defense suit or an extremely strong physique, there are few conventional methods that can resist it.

When the palace family came to the door to learn, the beggar version of the scorching sand once burned Gong Zi'an's face.

However, after an hour of study, Hong Fan still did not make any breakthroughs.

The shot is 800 degrees high, but the effective distance is only three meters.

Not even powerful enough to kill a pig.

This is conceivable.

On Chinese New Year's Eve, the Cui family's iron flower is a good example.

Fifteen hundred degrees of molten iron was blasted into the air by a shirtless blacksmith with a flower stick, and when it fell, it had already solidified, and the surface was only warm.

The same goes for sand.

The contact area between the particles and the air is too large, and the higher the speed of movement, the faster the cooling will be, so that it falls into the dilemma of being unable to balance high temperature and high speed.

[If there is no qualitative change in Yanliu's true qi, no matter how much the technique is improved, I am afraid there will be no breakthrough. 】

Hong Fan thought of it, and the scene when Hong Jian killed Wan Guangji came to mind.

The energy is light and silent, surpassing the six roots and six dusts.

A little spark strikes, and the flame frenzy is transformed.

This difference between the heavens and the flames is by no means simply a physical high temperature.

Hong Fan pondered for a moment, took out a pen and paper to record the details of the test, and then temporarily sealed "Scorching Sand V0.9".

The final item of the trial was a powered glider.

Leaving the woodland, Hong Fan walked onto a cliff with a drop of more than 100 meters.

After he advanced to the Realm of Harmony, the strength of the sand-cast items increased further, and the newly designed glider was already very different from before.

After all, this is half of the old business before the crossing.

The cockpit is a fully enveloped pupa shape, integrated with the wings, and the viewing window can be opened and closed at will.

The wing was changed to a convex Clark Y airfoil for maximum lift.

Fuller flaps are installed at the wing roots, which increases the wing area without gaining weight, and the lift coefficient is increased by 130%.

The front part is reserved to open and close the air intake, and there is a honeycomb inflammatory flow heating chamber, as long as the driver's kidney is not deficient, the power is on call.

The center of gravity offset algorithm of the glider has been improved, and the ailerons and tail rudder are built on the fly to greatly optimize the handling......

It is no exaggeration to say that the best glider in the previous life did not have the performance of this V1.7 version of the "Power Sand Wing".

The maximum ceiling is 5,000 meters.

The afterburner has a top speed of 200 kilometers per hour.

The conventional wing load is six kilograms per square meter, which can be doubled in extreme cases......

Along the newly opened forest path, Hong Fan galloped wildly.

After one breath, it reaches a top speed of 80 kilometers per hour.

Wrapped in a huge mass of sand, he leaped out of the cliff and turned into a golden swimming fish.

Volleying into the void, racing at extreme speed.

The blue sky is above, and the forest sea is below.

Endless blues and greens spread into the distance, connecting with his gaze farther than the distance.

Hong Fan greedily looked at the scenery and felt the air flow rushing wildly by the edge of his hair.

This feeling is like walking on the road against a typhoon in a previous life.

But this time it's different.

[Because this time it's not the atmosphere running, it's me flying.] 】

It's late afternoon.

The fiery sunset sets the heavens and will set the earth on fire.

Hong Fan whistled wildly, gliding towards the roses of the sky, indulging in the freedom that was once reserved for birds.
