Three days, just three days, Li Fei and Nangong Yuntian set off day and night, without stopping on the way, and finally stepped into the Dulong Cave area, which was only more than ten miles away from Dulong Cave.

Li Fei's heart was still filled with haze. He did not relax for a moment and continued to rush back to Dulong Cave without stopping. There was his most important sister Xiaorou, Luo Yu, a stupid and cute woman, as well as many subordinates who had high expectations for him, as well as the people. Unconsciously, Li Fei was involved in too much concern. He was no longer an orphan who had no relatives in his previous life. He had things that he needed to protect with his life.

Become stronger, become stronger endlessly. Only when you become stronger can no one dare to get involved in your anger. Only in this way can you have enough strength to protect everything you care about.

A few hours later, Li Fei finally saw from afar, the huge unique and familiar mountain in Dulong Cave, and then came close to it and found the entrance of the huge crack passage. There was no guard guarding him. His face couldn't help but sank. He looked at Nangong Yuntian and saw a hint of worry in the other party's eyes.

Li Fei took a deep breath and quickly walked into the crack passage. When he arrived at the dangerous area of ​​the passage red line sensing, the bead in his arms that controlled the entry and exit of Dulong Cave emitted bursts of purple light. In less than a moment, the slender and dangerous energy red lines dissipated one by one, and after Li Fei and the others passed, they returned to their original state again.

Nangong Yuntian, who had heard of Dulong Cave many times before, has a very unique defense system left by ancient civilization. Today, I finally saw it. Just based on the defense ability of the mechanism just now, it is estimated that there is no bead control. Even with their previous full strength of Xuanling Guard, it is difficult to pose any threat to this place. He couldn't help but ease the atmosphere and said, "Li Fei, don't worry too much. As long as this line of defense is there, Keith's strength will not cause any threat."

Li Fei shook his head and did not respond. If this was the case alone, he certainly had no worries, but if the character Harloris appeared and walked with Case, things would become mysterious.

Although after occupying Dulong Cave, he also made a series of investigations and found that there were only 3 beads that controlled Dulong Cave in Harloris's hands, which had all fallen into his hands at this moment, but who is really sure whether Harloris had left a hand.

After passing through the red line light energy area, turning to the right for dozens of meters, then passing a straight angle lightly. This is the last straight channel of nearly 300 meters. This channel directly penetrates into the first area of ​​the martial arts training ground. With Li Fei's modified eyesight, he can even clearly see some scenes in the martial arts training ground.

At this moment, this straight passage of nearly 300 meters is no longer as clean as before. On the two stone walls, there are still some remaining blood stains. Although it seems that someone has cleaned up again, the smell of blood that has not yet dissipated remains.

Nangong Yuntian also saw this situation. With his wisdom, it is naturally not difficult to react. What happened to Dulong Cave at this moment.

"Dingdeng..." Li Fei walked through the passage in a few seconds and walked forward to the martial arts training ground.

Nangong Yuntian, who was following behind, looked at Li Fei's back with a look of surprise. When did the physical strength of the demon maker also have this speed?

It seems that Li Fei is just a freak!

"Who..." Li Fei was just about to walk out of the end of the passage, but he heard a loud shout.

Li Fei was relieved when he heard this shout. Because he heard that the shout was nothing else, and the master was Wang Xi, the commander of the guard team. Not long after, looking through the passage, Wang Xi and many members of the guard team appeared at the martial arts field, each holding weapons, staring at the passage as if facing a great enemy.

In the straight passage, looking forward, Li Fei had already seen some scenes in the martial arts training ground. At this moment, the four steel carving castles built on both sides of the passage entrance had already emerged from thick fire. Although the degree of damage was serious, it was not compromised.

However, this is enough to prove that there was actually a battle in Dulong Cave, but from the situation where the Iron Carving Fortress had not been destroyed and Wang Xi's shout, Li Fei couldn't help but feel a little calm. It seems that even though the Cases found a way to pass the red-line light body area of ​​the crack channel, they did not have the ability to break through the Dulong Cave from the narrow passage.

"It's me..." Li Fei responded, and then walked out of the passage with Nangong Yuntian and came to the martial arts training ground.

"Sir? It's you, you finally came back!" Wang Xi shouted in surprise, and his tone seemed to be unbelievable.

"Lord." The guards also shouted, looking very excited.

Li Fei did not reply. He looked around and glanced at the venue one by one, calling out luck in his heart. Fortunately, after talking to Carosia and the others about the appearance fee for the demon soldiers at the banquet, he obtained a large number of 7-star crystals, he remotely controlled the interstellar base from a long distance, and once again produced 120 units of interstellar troops, and issued them to the martial arts training ground to garrison. Otherwise, if these 120 star soldiers were not stationed in the martial arts training ground, Li Fei would not dare to imagine whether he could survive the attack by relying solely on the interstellar troops in the eight celestial castles on the martial arts training ground.

Wang Xi's face looked much haggard. Not only him, but more than a hundred members of the guards present were also full of fatigue. However, due to Li Fei's return, they were all full of excitement and excitement.

Around the surroundings, there are also 120 interstellar infantry produced by Li Fei, one of which is quite common. It seems that the narrow and long terrain unique to the passage is not beneficial to the shooting of more than a hundred interstellar soldiers, so their attacks can only damage the four celestial forts away from the passage.

Moreover, because there are more than a hundred interstellar troops, they are stationed at 24 hours a day and do not need to rest at all, even if Case wants to play a raid, there is no way.

Li Fei nodded and gestured to everyone, and then said in a deep voice: "Thank you for your hard work, but at this moment I want to know what happened. All the senior management followed me into the third area."

After saying that, he summoned 12 engineers from the space grid, heading to four already burning and smoking castles, and began to repair them.
