The strongest undead system

574 The Heart of the Earth
"Sword Spirit, why am I feeling hotter and hotter?" Lin Yi frowned, and asked Sword Spirit, does this cave lead to the magma world deep underground?
The sword spirit replied: "Master, you have been crawling for half an hour. According to your speed, you have climbed at least several thousand meters in this cave. If you count the depth, it must be 2000 meters. At this depth It's normal for the temperature to be high."

Lin Yi recalled some geographical knowledge from his previous life, "Every time the ground is 100 meters deeper, it will rise by about 2000 degrees Celsius."These [-] meters, the temperature has risen by at least [-] degrees!
"No wonder." Lin Yi muttered, the terrifying depth of 2000 meters is enough to approach or see the magma in the earth.However, what surprised Lin Yi was that the deeper the ground, the harder the rock formation. Why did there appear a hole the same size as the entrance?

"Master, we'll be here soon." The sword spirit's voice rang in Lin Yi's heart, shaking Lin Yi's spirit.

Lin Yi was overjoyed and hurried down to climb down.

After about half a quarter of an hour, Lin Yi found that the road ahead had been blocked.The thing blocking the way is a very special kind of soil, from which Lin Yi can feel a great energy.

"Sword Spirit, the cave is blocked. I tried it, but I can't penetrate the soil at all, and I can't even hurt it!" Lin Yi was shocked. Just now, he even used the Dragon Slaying Saber , as sharp as a dragon-killing knife, but it can't destroy the soil.

The sword spirit emerged from the Dragon Slaughter Knife, its face was covered by a ball of light, and its body was almost transparent.

The sword spirit sensed the soil slightly, and then exclaimed to Lin Yi: "Boss, this soil is what I call treasure!"

"Oh?" Lin Yi raised his eyebrows, looked at the soil with some surprise, and said to Sword Spirit, "Sword Spirit, tell me about the origin of this thing?"

"Master, this is the heart of the earth!" Sword Spirit's tone revealed surprise.

"The heart of the earth was a very ordinary soil at the beginning. The formation method is similar to the rootless holy water I mentioned. It needs to absorb the aura of heaven and earth for a long time, even longer than the rootless holy water. It takes tens of thousands It takes years to form a soil the size of a person."

"Although this Heart of the Earth does not have the effect of life and death like the rootless holy water, it is much better than the rootless holy water in refining tools. When refining tools, just add a fingernail-sized heart of the earth to it , the attributes of the weapon or armor can be greatly improved! Its rarity is even enough to rank in the top [-] among the strange treasures of the Chaos Realm!"

"As long as there is a heart of the earth, there will be no heart of the earth for hundreds of miles, thousands of miles or even tens of thousands of miles."

"Since the Heart of the Earth was formed, it will continue to devour the ground below it, and slowly sink to the ground. A cave will be left where it passes. This kind of cave will never collapse, unless the Heart of the Earth sinks into the magma The cave will be destroyed by the blowout magma. I said why there is such a cave in this mine, it turns out that it is because of the existence of the heart of the earth."

Lin Yi curled his lips, and said, "Sword Spirit, just tell me whether the Heart of the Earth will help me or improve your strength?"

Without any hesitation, the sword spirit said to Lin Yi: "The Heart of the Earth has no effect on improving strength, so it is only useful to me. For you, Master, the role of the Heart of the Earth is to have a miraculous effect on refining weapons. As for other It is of no use at all.”

Lin Yi was not disappointed. Anyway, the heart of the earth can be absorbed by the sword spirit, which is the best situation.So Lin Yi said to Sword Spirit: "Sword Spirit, you have absorbed the heart of the earth."

"Thank you, Boss." Jian Ling immediately became happy, and it could be seen that Lin Yi gave up such a precious heart of the earth to Jian Ling, making it very grateful.

Lin Yi smiled lightly.

"By the way, boss, my current body is illusory, so I have to borrow your body."

"Come on." Lin Yi closed his eyes slightly, and agreed directly.

The sword spirit's mind slowly merged into Lin Yi's body, gaining control over Lin Yi's body.

Under the control of the sword spirit, Lin Yi's eyes suddenly opened without any emotional fluctuations.Raise your hands and gently place them on the surface of the heart of the earth...

"Boss, it's alright."

I don't know how long passed before the sword spirit's voice sounded.It was estimated that five or six hours had passed, and Lin Yi saw the sword spirit's thoughts exiting his body, so he immediately activated his thoughts and regained control of his body.

Lin Yi's eyes fell on the heart of the earth, which was about half left, and asked the sword spirit: "Sword spirit, why is there still the heart of the earth?"

"Because I have already absorbed the saturation, so I can't absorb the remaining heart of the earth. Master, I can absorb as much ore or natural treasures as I have. Once I absorb a certain ore, I can absorb it. If the power is saturated, I will never be able to absorb that kind of ore again." Sword Spirit explained to Lin Yi.

"This is a good habit." Lin Yi laughed, and did not pretend to refuse.

Then Lin Yi asked Sword Spirit: "Sword Spirit, if I remember correctly, you told me before that absorbing ore will increase your strength, right?"

The sword spirit laughed, it didn't understand Lin Yi's meaning, so the sword spirit said proudly: "Master, as long as my strength at this moment is below the strength of Xuanxian, I won't even try to touch you! Of course, this It's only protecting you."

Unexpectedly, after absorbing half of the energy of the heart of the earth, the sword spirit has the strength to compete with the masters of the earth immortal, which is a surprise.Although Lin Yi's strength has not improved, the improvement of Sword Spirit's strength is no different from that of Lin Yi.

"Master, take the remaining half of the Heart of the Earth. If you leave it here, it may sink into the magma someday." Sword Spirit said to Lin Yi.

Lin Yi nodded slightly, and then directly took the half of the heart of the earth into the system space.

"It has been detected that the host has obtained the Heart of the Earth. After testing by this system, the Heart of the Earth is not very useful to the host, so this system recommends that the host sell the Heart of the Earth in the system mall."

"Can I sell you the Heart of the Earth?" Lin Yi's eyes widened.

However, Lin Yi didn't hear the systematic answer, because after Lin Yi put away the Heart of the Earth, the cave in front of him began to loosen.

"Come on! The heart of the earth is gone, this cave is about to collapse! Master, go!" The anxious voice of the sword spirit rang in Lin Yi's heart.

Before the voice fell, the cave began to turmoil.The ore in front of Lin Yi directly opened a hole, and crimson hot magma flowed out!
"Fuck!"
