As the crisp cracking sound of the rune sounded, Lin Feng also stabbed the dark cross sword into the heart of the Split Plains Tiger at the same time, of course, this scorching heat also made Lin Feng let go of the hands that were clutching the dark cross sword, and the whole person could not resist this attack and was shot away.

"Wow......!"

Yang Tian finally roared for a long time, and the Split Plains Tiger finally collapsed, splashing dust and dirt, as for Lin Feng, who was lying on the side and pouring himself with healing potions, he was also resting.

The rune fragments on his body fell to the ground when he stood up, and the silver-white runes had lost their due use, even if Lin Feng took it back, it would be used as fuel at most.

Walked over and took the dark cross sword back, it was still hot but it could still bear it, and after pulling it out, a little golden blood flowed out of the heart wound of this ripping tiger, which was quickly covered by blood red, and this golden blood was carefully put into a bottle by Lin Feng and put it in his backpack.

This kind of thing is of great use to the core of science and technology, and of course it is also very useful to Lin Feng himself, it is a powerful healing prop, if there is enough amount, it can even permanently increase an attribute and resistance, but for now, it is still an item to make powerful props.

The corpse of this Rippping Plains Tiger is also not easy to handle, and according to its last roar, many wild beasts will soon gather in this place, or if you leave quickly, Lin Feng may be torn to pieces by the fierce beasts that have driven over, and a corpse will be eaten properly.

Grabbing the tail of the Rippland Tiger and dragging it, although the appearance looks very large, it seems that most of the blood in the body has flowed out, and some of it has been burned, and it is not very heavy to drag.

Lin Feng, who was racing against time, seemed to have burst out of his potential, this pulling speed was much faster, and his luck was also very good, he didn't encounter any fierce beasts blocking his way along the way.

Throwing the corpse of the Ripping Plains Tiger into a small river, if you want to let the smell of blood continue to drift, it will definitely attract beasts, whether it is strong or weak, as long as it is a beast, it needs to fight, and Lin Feng is now wearing a color on his body, although the fish scale soft armor ensures that he will not be fatally injured, it is useless.

Now the battle is dragging out time, and when the time comes, once there are more beasts that have come for a long time, they will still not be able to escape the palm of the beast's hand, and the result will not change much.

This is also the reason why Lin Feng threw the corpse of the Split Plains Tiger into the river, a little less smell of blood can delay for a longer time, there is no doubt that this Split Plains Tiger can at least unlock some powerful things, and it took more than ten seconds to drag it up.

Because it was filled with water, the corpse became heavy, and after looking at the smoke that still hadn't disappeared, Lin Feng could at least judge that the general direction was not wrong, but it took a lot more time and strength to do so, and after looking at the sun, there was already the idea of falling.

It was already afternoon when Lin Feng came, and after such a long time, it was evening, and he felt normal, but he was afraid that he hadn't returned to the cave before the sun set.

If it was like this, the beast that only came out at night outside would definitely be interested in teaching him to be a good man, suddenly the sky was wrapped in darkness, and bats also came out of the cave to feed, but the huge number made Lin Feng a little frightened.

Fortunately, these bats are not vampire bats, otherwise the Split Plains Tiger that passed just now in a circle would have turned into a Split Plains Dead Tiger, which also made Lin Feng speed up his actions.

The blue-purple light was a little faint in front, and the bonfire had been extinguished and lost the ability to guide the way, but the light of the altar still made Lin Feng excited, and it was not far away to see this light.

The obscured sky was finally returned by bats, and a bright moon had appeared in the sky, although the sun still had a red glow, but it was almost gone, and it didn't last long.

Sitting directly next to the bonfire, the night of this isolated island has not yet reached the coldest time, the corpse of this Split Plains Tiger was put into the cave, Lin Feng did not dare to light the fire casually, this would expel the fierce beast but also attract the fierce beast, and seal the entrance of the cave with some branches and weeds.

You can't even emit the light at the heart of the technology, or nothing will happen.

The entire Rift Plains Tiger was made into two identical bone altars, of course, the flames of this altar were reddish and the energy input was relatively strong, as for the tiger skin, it was willfully turned into a sleeping bag by Lin Feng, and it didn't matter if it was really useful.

As for the horn that made a strange horn, it was only useful to attract tigers, and the tigers didn't listen to the call, but it was one of the few things that could bring out a copy.

I don't know what the principle is based on, this Split Plains Tiger left Lin Feng with a piece of flesh, and the other blood and flesh have become a special creature, it seems that because the whole appearance made of the blood and flesh of the Split Plains Tiger is also a bit biased towards the appearance of a tiger.

A strange creature has no attack power, but it can help Lin Feng open up this cave, after all, if you put three altars, you can occupy most of the space in the cave, and you should also get a creature that can help expand the space, if you have enough flesh and blood, you can pinch out anything.

There is not much wisdom and so much flesh and blood can only make one, the most precious drops of golden blood of the Rippling Tiger were poured directly on the core of science and technology, and the original white light became golden yellow, this is the core of science and technology, but it does not mean that you can only play the industrial technology side.

Enough energy and resources can support it to make a lot of things with different biases, of course, only the pure technology side can have a complete C-level props to be manufactured, as for the others, they are all incomplete, that is, there are no resources in the early stage, and there is a little need for some garbage in the back.

However, Lin Feng, who not only has no resources and no time, but is dying, and developing pure technology is dying, and making these things that are a bit nondescript on the mysterious side consumes the least resources and is the most useful for Lin Feng.

As for the full tech side? Forgive Lin Feng for not having the ability to do it.

When he can get this thing in the game, then the complete technology side props will appear in his hands, anyway, there is no such possibility now.

The golden light emitted was not only unlocking things, but also knowing that Lin Feng's focus was constantly modifying the data, and after absorbing all the golden blood, the entire technology core had some special fiery red textures spreading on it.
