The small soldiers on the frontier at the beginning killed Liu Ye, the Han God of War, and Lu Lingqi

To sum it up in one sentence: There are ghosts in this world!

According to Shen Hao, the so-called cold month refers to the last month of the year.

In this month, the yin energy in the heaven and earth is the heaviest. Whenever night falls, evil spirits will appear.

They are invisible and invisible, and once they are attacked, there is basically no solution. It can range from a serious illness to a life-threatening illness.

Wenxiu's literary spirit can effectively resist the invasion of evil spirits, but it can only resist.

Only warriors who have cultivated Qi and blood can completely eliminate them with the help of Qi and blood.

If you just want to achieve this level, ordinary soldier blood and general blood will definitely not work. It is estimated that you must at least start with Hou blood.

But there are probably not many people in the world who can refine their Qi and blood to this level.

Therefore, every cold month, all forces will enter the stage of self-cultivation and regeneration in a tacit understanding, and will not take the initiative to provoke war.

When the barbarians sent an army of 100,000 to attack the pass, they also made sure that the Han Dynasty would not make any major military mobilizations as the cold month approached.

Otherwise, even if you give them ten courages, they will not dare to attack the border with a large army. At most, they will send small groups of troops to harass them from time to time.

"It sounds like the door to hell is wide open." Liu Ye rubbed his chin thoughtfully.

Although he was a little surprised that evil spirits existed in this world, he was relieved after thinking about it carefully.

As the saying goes, if the lonely sun does not give birth, the lonely shade will not grow.

If there is a yang side to the world, there must be a yin side.

In Liu Ye's view, the so-called evil spirit should be just a special existence formed by condensation of a certain Yin attribute aura.

This can also be regarded as a way for heaven and earth to maintain balance. From time to time, some yin energy is released to neutralize the aura.

Humans are born in the Yang category, and if the two auras conflict, one of them will inevitably have problems.

Of course, this is just Liu Ye's personal understanding. As for whether it is consistent with the actual situation, he cannot guarantee it.

"But those aristocratic families should understand the hidden meaning."

The aristocratic family has a long heritage, and even the major cultivation systems are all from the hands of their ancestors. They must also have in-depth research on the so-called evil spirits.

"Back to the city!"

Liu Ye waved his hand and returned to Yanmen Pass with everyone and many trophies.

It’s still not appropriate to act rashly at this time. Let’s find out the details from Mr. Meng and the others first.

……

When he returned to Yanmen Pass, Liu Ye also discovered some abnormal phenomena.

It's not dark yet, every house has closed its doors and windows early, and there's not a single pedestrian in sight on the street.

Even the soldiers guarding the city were much fewer than usual, and they looked like they were ready to return to camp at any time.

Obviously, once it gets completely dark, Yanmen Pass will no longer be defended.

After all, no one dares to invade at this time of day.

Along the way, Liu Ye could smell the smell of blood from time to time.

After asking Shen Hao, he found out that this was black dog blood prepared by the people to ward off evil spirits.

"Good guy, is it popular in this world to use black dog blood to ward off evil spirits?" Liu Ye secretly claimed to be surprised.

Black dog blood is a yang thing, especially fresh black dog blood. The yang energy has not dispersed, so it can be used to deal with the evil spirits of yin attribute.

How effective it will be is unknown.

But since it can be passed down to this day, I think it will have miraculous effects.

After handing the trophies to the logistics office in exchange for military merit, everyone went back to their homes.

Seeing their impatient looks, Liu Ye couldn't help but shake his head and laugh.

Unexpectedly, this group of elite soldiers and generals who were not afraid of death on the battlefield were also afraid of the so-called evil spirits.

Sure enough, the unknown is the greatest terror!

Back in the courtyard, the sky had become dark.

A chilly air began to fill the air.

"Is this Yin Qi..."

With the help of his mental power, Liu Ye could "see" more wisps of black gas in the air, which gradually increased as time went by.

Whenever these black gases came close to three feet around him, they would automatically disintegrate and then re-condensate not far away.

Seeing this situation, Liu Ye suddenly spread his restrained mental power to the surroundings.

Wherever it passes, the Yin energy subsides, as if there is an invisible force pushing it outward.

When the mental power spreads to a radius of 100 meters, it can no longer move forward.

This is not Liu Ye's limit, but suppressed by Yin Qi.

"receive."

Gathering his mental power again, the Yin Qi immediately gathered again and circulated around three feet around Liu Ye.

Obviously, like Wen Qi, mental power can only play a defensive role and cannot eliminate Yin Qi.

"Then how does qi and blood destroy yin qi?"

Thinking of this, Liu Ye completely absorbed the spiritual power surrounding his body into the sea of ​​consciousness.

The next second, the surrounding Yin Qi was like a fish smelling fishy smell, scrambling to squeeze into Liu Ye's body.

"Hi~"

Even with Liu Ye's physical condition, he couldn't help but shudder.

But then, as they seeped into the blood, like a mud cow entering the sea, they disappeared without a trace in an instant without making any waves.

Slowly, more and more Yin Qi gathered, and Liu Ye did not refuse anyone who came, destroying them all.

If you look down from above at this time, you can see three slowly rotating vortexes of Yin Qi.

The largest group came from Lufu, with a diameter of one kilometer.

Next is the small courtyard where Liu Ye is located, with a diameter of 500 meters.

The smallest one is Zhang Liao's mansion, which is only about 50 meters in diameter.

In addition, there are a lot of black air masses of different shades distributed throughout Yanmen Pass.

If you observe carefully, you will find that the stronger the qi and blood in the area, the higher the concentration of yin qi in the surrounding area. The main focus is a confrontation.

"I see."

After feeling it silently, Liu Ye probably understood the reason why the Yin Qi was gathering towards him.

If Yin Qi is regarded as the waste gas produced during the movement of heaven and earth, then these warriors with strong Qi and blood are equivalent to waste gas treatment plants.

This time of year is the time when heaven and earth deal with waste gas.

The stronger the qi and blood, the higher the efficiency of destroying yin qi, and the wider the range of attracting yin qi.

It is not difficult to imagine that if a city has a strong man with emperor blood or even dragon blood level, half of the Yin Qi will be absorbed by him.

In this way, the pressure on ordinary people will be much less.

However, this ability is only related to the quality of Qi and blood itself, and has nothing to do with the realm of cultivation.

This is why Lu Bu is obviously much stronger than Liu Ye, but the diameter of the Yin Qi vortex is only twice as large.

After all, Liu Ye's Qi and blood quality is only one level lower than Lu Bu's, and it only takes one blood transfusion to improve it, so the difference is very small.

As the Yin Qi continued to gather in the body, Liu Ye's Qi and blood were also being rapidly consumed.

However, the hematopoietic ability of golden bone is the best in the world. It is often replenished immediately after being consumed a little, so there is no need to worry about being exhausted by the yin energy.

"what?"

Suddenly, Liu Ye found that the quality of qi and blood in his body had strangely increased, almost one thousandth.

Don't underestimate this improvement.

His current Qi and blood quality has reached the limit of imperial blood.

If he relied on his own tempering to improve the quality of Qi and blood by one thousandth, it would be impossible without a few months of effort.

But now it only took an hour of absorbing the Yin Qi to do it.

This efficiency can almost catch up to one-tenth of the tempering speed of Dragon Blood Pill.

"It seems that even Heaven and Earth understand that you have to be paid for your work. This is much better than those black-hearted capitalists."

"I just don't know if there is an upper limit for this thing." Liu Ye thought secretly in his heart.

If you can continue to temper like this, in a month, you may be able to directly improve the quality of your qi and blood to the dragon blood level!

As for divine blood, Liu Ye didn't dare think about it.

Knowing that absorbing Yin Qi had the benefit, Liu Ye immediately got excited and wanted to suck in all the Yin Qi in the city.

It's a pity that this thing cannot be actively absorbed, and can only passively wait for the Yin Qi to penetrate into the body, which is very painful.

Soon, it was late at night, and the system prompt sounded on time.
