Without the endless energy source of blood marrow, Li Qing's sustained combat power has been greatly affected.

His extraordinary skills can no longer be squandered as wantonly as before. Each transcendent skill can only be activated three times a day. The primary charge, which can only consume physical strength, is a skill that cannot be lightly fired.

Although the Nightmare Demon Body is powerful, it can only be used once a day. After the five-minute duration, you will fall into a weakened state with 50% reduction in all attributes. Therefore, it can only be used as the most powerful killer feature, and it must be used with caution.

If he just goes head-to-head with the strong, his current ability is enough. With the Nightmare Demon Body and extraordinary skills, it is not a problem to kill the strong people in the middle of the Pillar Kingdom. The strong people in the high and even extreme sections of the Pillar Country can also play a dozen. Who wins and who loses, you will know after fighting.

But although he has a strong ability to fight alone, if it is a big battle with thousands of troops, it is far from enough.

After all, his regular combat power was only close to the thirteenth-level Black Knight. Even if he was stronger than an ordinary combat rank of the same rank, if he only used his conventional combat power to fight the enemy, he would be able to fight against a fifteenth-level combat rank in the sky.

Therefore, Li Qing must find a way to improve his conventional combat power.

And the method that can improve the conventional combat power, in addition to the superb martial arts that need to be honed for a long time, is Chu Lingfeng's Dan Dao system.

Chu Lingfeng cultivated the true qi vortex, and there was true qi running in the dantian. On the surface, she only has an eighth-level strength, but when she invokes her true qi and blesses her whole body, her combat power can increase by leaps and bounds.

With the blessing of True Qi, she can improve her strength, physique, agility, and perception in an all-round way.

And that's just regular combat power. True Qi can also be used to activate transcendent skills, but it is much larger than the consumption of the amplification attribute.

And the recovery speed of True Qi is also amazingly fast.

The amplification attribute will continue to consume true qi, but at the same time, it will also continuously absorb the heaven and earth aura in the void to make up for the consumption.

Although it is impossible to compare the replenishment speed during the battle with the consumption speed, as long as he does not use the extraordinary skill that consumes a lot of true qi, with Chu Lingfeng's current true qi strength, he will continue to fight for seven or eight hours without stopping, and the true qi will be consumed.

After that, you only need to meditate for three or four hours to replenish the true qi in the dantian.

In terms of explosiveness, Chu Lingfeng is far inferior to Li Qing. But in terms of combat endurance, Chu Lingfeng is far above Li Qing.

If Li Qing continued to fight without stopping, and he couldn't plunder enough energy enhancement attributes to recover his physical strength, even if he only fought in a regular way, he could only hold on for three or four hours at most, and his physical strength would be exhausted.

Therefore, Li Qing had long wanted to learn Dan Dao cultivation from Chu Lingfeng, firstly, to enhance his soul power, and secondly, to cultivate his true qi and enhance his long-lasting combat power.

During the two-day voyage to Zhongshan Island, Li Qing had already asked Chu Lingfeng for advice on the cultivation method of Dan Dao meditation. While at sea, Li Qing practiced martial arts during the day and meditated at night, and soon achieved results.

Li Qingyuan thought that Dan Dao meditation was very difficult, and he was afraid that it would be difficult for him to get started.

But to his surprise, his Black Knight combat state was unexpectedly suitable for meditation.

In the combat state, in the killing mode, he will not have any distracting thoughts in his head, and even all his emotions have disappeared completely, his thinking is extremely pure, extremely rational, and calm to the point of almost coldness.

After deciding that the goal was meditation and turning on the battle mode, he entered a deep meditation state without any effort.

He has great strength in his own right, and his vision is far greater than before. With the body of a strong person, carrying out basic cultivation will have the effect of getting twice the result with half the effort. And his perception is many times stronger than that of his combat position at the same level. If you have a strong perception, you will have a strong mental strength. With strong mental power, meditation is twice the result with half the effort.

The two of them get twice the result with half the effort, coupled with the black knight's combat state with a pure mind and distracting thoughts, so that Li Qing has completed the basic meditation in only two nights during the sea voyage.

I was busy preparing for the battle last night, which delayed my cultivation. Today, the strong enemy is pressing, and Li Qing wants to take advantage of this pressure to sharpen his guns in battle, open up the inner and outer diaphragms, draw qi into the body, and cultivate true qi.

Outside the bunker, there was a lot of gunfire. Shells often smashed on the pillbox where Li Qing was located, making a dull roar and shaking down clouds of dust.

Li Qing was completely forgetful and unmoved.

After completing the basic meditation, he was able to perceive the state of the aura of the outside world.

Before he began his Dan Dao meditation cultivation, he could only perceive the existence of heaven and earth aura, and could not see the specific details. And now, in his perceptual perspective, the aura that is invisible to the naked eye is a colorful point of light.

Those points of light are lively, soft, dignified, or intense, bright and warm, or dark and cold...... Each point of light represents the aura of a certain attribute - or "element".

Spiritual light points filled the air, everywhere. They are like little elves, floating in the air, constantly moving, waiting for people to guide them to capture them and construct them into extraordinary powers.

Li Qing is now trying to introduce them into his body with perception.

He turned his perception into an invisible tentacle of spiritual power, touching those points of spiritual light.

The aura point of light is not a living being, and it will not escape his capture. He quickly caught many spiritual energy points, introduced them into his body, pulled them into the meridians, and guided them to circulate in the meridians with the Dan Dao Heart Method.

This step is not difficult. Because Li Qing originally had an extraordinary physique, the Strength Seed in his heart would also guide the aura into the Strength Seed on its own, constituting his extraordinary skill. Therefore, Reiki is not exclusive to him.

The difficulty lies in how to condense the spiritual energy into true qi and leave it in the dantian.

His Strength Seed is a direct introduction of Spiritual Qi into the heart, and it is processed into an extraordinary skill in the Strength Seed. The enhancement of his attributes was also done by the strength of the seed. The Strength Seed processes the extraordinary energy he has taken from him into energy that strengthens his attributes, improving his various attributes. Li Qing himself was not subjectively involved in this process.

Although the force quantity seed has become a part of Li Qing's body, Li Qing only knows the operation of the force quantity seed but does not know the reason.

It's as if everyone has a digestive system, but no one is actively involved in the functioning of the digestive system. Even if we know how the digestive system works, ordinary people cannot actively manipulate the digestive system to digest food, convert energy, and eliminate residues with subjective consciousness.

The dantian and meridians can also be regarded as a digestive system. Spiritual energy is introduced, circulated and digested in the meridians, forming true qi, which enters the dantian for storage. Excess impurities are discharged in the second half of the cycle.

This is the process of digestion of Reiki.

It's just that this process requires Li Qing to take the initiative to participate and guide.

At first, the digestion of Reiki did not go well. After Li Qing easily introduced the aura into his body and entered the meridian circulation, the aura disappeared quickly. The formless and qualitative aura can easily escape from the meridians and be scattered.

Li Qing was not discouraged and continued to concentrate on cultivating.

He constantly draws qi into his body, incorporating aura into the meridians and circulating. In the process, the aura continued to escape, but after his unremitting efforts, finally some of the aura remained in the meridians and was guided by him to circulate.

After running in the meridians for a while, the impurities in the aura were refined, forming a more pure and condensed energy. After the most lu, he entered the dantian, and under the guidance of Li Qing, he stayed in the dantian, forming a very subtle true qi vortex.

The True Qi Vortex was extremely small, only one-tenth the size of a needle tip. It looks like it could dissipate at any moment.

Li Qing didn't dare to be careless, and persistently introduced qi into his body, condensed his true qi, introduced it into the dantian, and joined the whirlpool of true qi. The True Qi Vortex continued to grow and gradually stabilized. When it grows to the size of a pinpoint, it finally stabilizes. Without Li Qing's deliberate guidance, he can also operate on his own in his dantian and exist stably.

At this point, Li Qing's second "Strength Seed" has finally taken shape.

Since then, he has had two "power seeds" and two power cores.

Although this second Strength Seed was still very weak, as long as he persevered in irrigating and cultivating unremittingly, one day, the seed would grow into a towering tree.

"Li Qing, the Amaterasu Army is going to attack!"

The figure flashed at the gate of the bunker, and Chu Lingfeng, who was dressed in cyan battle armor, walked in, and said quickly: "Our open-air batteries have all been knocked out by the Amaterasu fleet, and the Amaterasu fleet is still suppressing and shooting us. Amaterasu landed five kilometers north of the port and set up a camp within two hours. Now an army of 3,000 men has set out from the camp and is heading for the port. With the speed of the Amaterasu Army, you can attack in a maximum of ten minutes! ”

If it is an ordinary army, even if it is acted on a rapid march, a distance of five kilometers, it will take a long time. But the army of this worldly realm, the weakest ordinary soldiers, also has the strength of first-class warriors. The artillerymen generally have the strength of three or four levels, and they can run fast when pushing the artillery.

With the strength of the army of this world, it only takes ten minutes to cover a distance of five kilometers by maintaining a formation and marching in full gear.

Hearing Chu Lingfeng's voice, Li Qing finally woke up from the fighting state. He opened his eyes, the scarlet pupils flashed red, Huo Di stood up, picked up the dragon tooth treasure knife, and strode towards the door.

Walking out of the bunker, Li Qing looked around, only to see that the fort was filled with gunsmoke and fires broke out. The ground was littered with iron balls and rubble, and there were bloody stumps everywhere. When I looked up, I could see that the sky was still raining down.

The Amaterasu fleet did not stop shelling after knocking on the open batteries of the harbor fortress. Although the defenders in the fort had taken refuge in bunkers and the effect of the Amaterasu's artillery bombardment had been greatly reduced, the Amaterasu fleet was still suppressing the firing pressure all the time to cover the attack of the land division.

The Imperial defenders hid in bunkers, certainly not afraid of the shelling of the Amaterasu fleet. But Amaterasu's land division was about to attack, and the Imperial defenders always had to get out of cover and prepare for defense. At that time, we will have to continue to endure the raining shells.

Chu Lingfeng stood beside Li Qing, looked at the groups of cannonballs falling from the sky, and said, "Although there are many fully enclosed bunkers in the fortress, there are also many open-air defense lines. Those open-air defense lines can't be ignored, otherwise the Amaterasu Army will rush in directly. But this time, the soldiers had to withstand the shells of the Amaterasu fleet and exchange fire with the Amaterasu army. The situation is not in our favor! ”

According to Chu Lingfeng's estimates, unless the two armies are close to within twenty meters, the Amaterasu fleet will always be able to provide artillery support for the land division. Amaterasu's fleet is fierce, and if the Imperial defenders fight Amaterasu under artillery fire, they will surely suffer heavy casualties.

"Then let the Amaterasu Army come in and fight them in street battles."

As he spoke, Li Qing walked up to a fully enclosed artillery fortress on the north wall, looked out through the cannon window, and saw that the black pressure was pressed against the Amaterasu land division, which was pressing towards the fortress with a rapid march, and it was only less than four kilometers away from the fortress, and within a few minutes, it could be put into battle.

"Only by putting the Amaterasu Army in and forming a melee can the Amaterasu's firepower superiority be neutralized." Li Qing continued: "The terrain in the fortress is complex, and the Amaterasu army will be forced to disperse after coming in, while the officers and men of our army are familiar with the terrain and can form a local strength advantage in the movement. In this way, the strength advantage of the Amaterasu army can also be partially offset. So, they have to be put in! ”

Although Li Qing does not know how to command, he still knows the basic concepts.

Abandoning the outer defensive line and putting the Amaterasu army into the fortress to fight street battles was the only way to offset the Amaterasu's superiority in firepower and strength. Otherwise, with the artillery fire of the Amaterasu fleet guarding the open-air defense line, with the number of defenders in the fort of less than 3,000 people, I am afraid that it will be exhausted in less than half a day.

"Pass my order, abandon all the outer defense lines, and let the Amaterasu Army in to fight!" Li Qing looked back at Chu Lingfeng, and a cruel smile flashed in his red pupils: "I'm going to turn this fortress into a meat grinder and drain the blood of the Tianzhao Army!" ”

Chu Lingfeng simply responded, left the fort, and gave the order.

At the top of the mountain, Su Su saw that the imperial soldiers in the bunkers of the outer defense line of the fortress under the mountain had come out of the bunkers and quickly retreated to the inside of the fortress in the rain of cannons, and couldn't help but nod slightly.

If Li Qing had not given the order to abandon the outer defense line, Su Su would have given the same order when the Amaterasu army attacked.

The Amaterasu Army's superiority in firepower and strength was too great, and the gains of holding the outer defense line outweighed the losses. Only by fighting in the streets can the Imperial defenders have a slight advantage.

The 3,000 Tianzhao army marched to a distance of 200 meters north of the fortress before stopping the whole group.

While the Amaterasu Army was in formation, a total of thirty guns were rolled out of the gap in the formation and lined up on the north side of the fort. In front of each cannon, there are two heavy-armored wrestlers holding tower shields to cover them. The gunners, under the cover of shield-wielding wrestlers, moved quickly to reload the medicine bags and shells.

Five more Xiyi people in white robes and holding long staff walked to the front of the battle, surrounded by a group of heavily armored and shield-wielding wrestlers. Every white-robed Xiyi is guarded by at least ten shield-wielding wrestlers.

"Magician?"

Seeing the five white-robed Xiyi people, a strange smile appeared on the corner of Li Qing's mouth, and he strode out of this fully enclosed fortification, and walked to the highest point of the north city wall.
