On the Seven Towers

Tasia chose the west side of the stone path according to the direction pointed by Xiao Chen. Xiao Chen also followed their direction. One of them was on the ground and three of them were underground. However, Tasia and the others only had to move along the stone path, but Xiao Chen had to climb over various obstacles, some of which were houses and some of which were gardens. Sometimes it was necessary to bypass enemy sentries and even camps where large groups of troops gathered. Xiao Chen remained invisible, and at the same time used the flying technique on himself, trying to keep the distance between him and Tasia and the others within a range where they could communicate clearly.

"Wait a minute! We have a door here!" Tasia said.

"Door? Is it blocking the stone path?" Xiao Chen asked.

In front of Tasia and the others is a square stone door, which completely blocks the stone path in front. The door rises from below, and you can see that there are half-finger-wide gaps on the ceiling and both sides. , allowing the magic lines that make up the magic circle to pass through, but people will be unable to move forward.

"Let me try the crystal stone just now." Tasia took out the crystal stone that opened the door before and placed it on the stone door, but the magic circle on the door flickered for a moment and then dimmed again. "That crystal stone No stone can open this door."

"It's not surprising. This should be a blocking door to prevent enemies from running to important places through these magic passages. The stone you stole may just be the key to certain areas. Marquis Baldini should put the keys in different areas The key is given to the person in charge of the corresponding location," Xiao Chen said.

"What should we do? Do we need to take a detour? We have encountered several forked roads in front of us, but we have been running westward and have not explored those roads." Tasia said.

"I guess those passages will also have such partitions. I even suspect that this may be the defense of the node. Maybe behind the door is the node we are looking for." Xiao Chen raised his head and looked around carefully, and found that it was no longer far from the city wall. Far away, he bypassed a house in front of him and saw a faint light beam about a hundred meters ahead, leading to the sky and shooting directly at the shield in the air. The light beam and the shield were connected together as if they were pillars supporting the shield dome. The color of this light beam is very light, and its color is consistent with the shield in the sky. If it weren't for the sky getting dark now, Xiao Chen would have run closer again. You won't notice it at all. The emission point of the light beam seemed to be behind a few houses in front.

Xiao Chen said: "I seem to have found a suspected node on the ground. It is not far from the edge of the city. There is a light pillar connected to the shield from the ground. Maybe under this light pillar, you are going to The place to look for. By the way, isn't Elena good at negative energy magic? I remember that there is a corrosion spell that has the effect of turning fossils into mud. Can it be used on that door? "

Elena slapped the door, and there was a dull sound. The door didn't seem to be very thick. She said, "Let me try."

Elena's hands danced in the air, and then a dark purple light ball appeared in her hands. She pressed the light ball against the door. The stone made a hissing sound when it encountered the light ball, as if it was composed of some kind of light ball. The internal structure is falling apart. But a few seconds later, a thin light yellow light curtain suddenly lit up on the door. The light curtain forcefully pushed out the negative energy released by Elena, and there was only a dent one centimeter deep on the stone door. hole, and then Elena's magic can no longer harm the stone door.

"Light yellow energy shield? Can't reach the stone gate behind the shield?" Xiao Chen said after listening to Elena's report, "I suspect this is the same thing as the city protective shield outside. Once someone hurts the stone gate, it will Will activate the shield to protect the stone gate."

"We have tried several magics, but none can break this shield. Only dispersion magic will have some effect, but it can only slightly weaken the shield when the magic is released. I cannot continue to cast dispersion magic." Tasia said.

Xiao Chen said: "Let Xiaobai give it a try!"

Xiaobai understood what Xiao Chen meant. It flew to the stone gate and flew along the stone gate from top to bottom, as if feeling the distribution of magic energy. Finally, it chose to fly to the bottom of the stone door, coiled itself into a circle, and attached itself to the shield.

Both Tasia and Elena felt a wave of magic. Xiaobai's small body was like a black hole, not only absorbing the magic power of the shield all over the door, but also cutting off the magic power replenished from the ground.

Xiaobai shouted at Elena, meaning to speed up the time!

Elena continued to use corrosive magic. It took her about a minute to corrode a hole the size of a fist. After cleaning up the dust in the small hole, she looked into the hole and saw a short passage behind it. At the end of the passage is a room with a large magic circle on the ground. Perhaps because of the protection of the stone door, there is no manpower in the room behind the stone door. "I think we found the place," she said.

Elena continued to use corrosive magic to make holes in the door, and connected the holes into a circle. But when she finished drilling four or five holes, Xiaobai flew up from underneath. As soon as it left, the shield of the stone door came back and wrapped the entire door inside again. Elena had to stop. Next action.

At this time, Xiaobai was flying staggeringly like a drunkard who was full of wine. He twisted in the air for a while, then burped, and a golden magic crystal popped out of his mouth. Tasia picked up the magic crystal from the ground and found that it was a top-grade magic crystal in good condition. Weiwei input mental power into it, and a pale golden shield actually opened in front of her, which was exactly the same as the shield on the door at this time.

"Oh my god! Xiaobai actually has the ability to turn the absorbed energy into magic crystal!" Tasia said.

"Master Kona told me that this is Xiaobai's way of dealing with the overflowing energy after absorbing it," Xiao Chen said.

"Then isn't it just a magic crystal making machine?" Tasia said.

"Don't you notice that Xiaobai looks tired? This must be very difficult for him," Elena said.

Xiaobai nodded. It was obvious that his energy was not just right. But after spitting out the magic crystal, it was able to absorb magic power again. It consciously coiled up into a ball again and stuck it to the door.

Elena and Xiaobai worked together, and it took about half an hour to finally cut out a circle with a diameter of less than one meter in the middle of the stone door. Elena and Tasia used their strength together to push the fallen stone slab to the ground, and an entrance large enough for people to pass appeared in front of them.

But just when they were about to get in, a voice came from behind: "You, who are you!"
