After hearing what Holmes said, Du Yuqi couldn't help but nodded slightly:

"That makes a lot of sense!"

Holmes continued:

"So, my friend re-entered the Imperial Test Site and began to try living here. Then, he actually found a drug that could neutralize and excrete the heavy metal elements in his body."

Having said that, Holmes glanced around and said:

"Those are the aquatic plants growing around us! And some fish that grow in the water! These creatures grow in the water that contains special ingredients, but they don't have any related special ingredients in their bodies. This means they must have some way to remove the special ingredients in the water. My friend has been eating reed buds and young leaves of calamus for many years. After one month, his condition stabilized, and after half a year, all the heavy metal elements in his body were cleared."

After hearing what Holmes said, Du Yuqi pondered:

"If that's the case, we can actually eat some of these plants and fish occasionally. Even if we don't drink the water here, we still have to breathe. The water vapor we inhale will inevitably be absorbed, so we can't rule out the possibility that some harmful substances will seep into the body. Although the amount ingested is definitely small and won't make people sick, it is still a hidden danger. What's more, if we want to find blue compound algae, we have to go into the water and come into direct contact with this polluted water source!"

The next step is to look for the blue compound algae. There are not many of this algae, and it will not grow in deep and fast-flowing water. It is more like the pitcher plant on land. The Venus flytrap, a "carnivorous" plant, can paralyze small fish and shrimps in the water with its whisker-like stingers drifting in the water, and then trap and eat them.

So if you want to find this thing, you can only paddle a rubber boat and go to the shore or swamp, and this must be an area with more small fish and shrimps. Fortunately, this thing has a distinctive feature, which is that it is a distinct blue color, which can be said to be very advantageous in identification.

In this situation, the group naturally split up to improve efficiency. Since they were all operating in the water network area, they would jump into the water if they saw something was wrong, so safety was not too important.

Du Yuqi then paddled in one direction. After about two kilometers, he said hello to his companions and started to head towards the nearby tributary. Then he saw that the tributary in front made a big U-shaped bend. Obviously, there was a piece of land surrounded by rivers on three sides.

The terrain here is originally very low-lying, forming a silted river beach. A large number of green plants such as water lilies grow here, and the water flows quite gently. Du Yuqi also saw several waterfowl similar to kingfishers standing motionless on the lotus leaves, closely observing the conditions on the water surface. Once there is a situation, they will suddenly fly over to catch fish. This shows that there are many fish and shrimps here. At the same time, just as Du Yuqi rowed closer, he heard a few "plop" sounds of falling into the water. It should be the sound of startled frogs diving, which is completely consistent with the growth environment of blue complex algae. Therefore, Du Yuqi was immediately delighted and rowed towards the river bay.

It is definitely not possible to row fast in the river bend at this time, but Du Yuqi was rowing alone and identifying plants at the same time, so he did not need to go very fast. Soon after he rowed in, his eyes lit up and he found a flash of emerald blue underwater. He looked carefully and immediately found that there was a jellyfish-like plant below, with long tentacles, slowly floating in the direction of the water flow. It was parasitic on the stem of a plant similar to a water lily, and its shape was quite strange.

After looking carefully, he found that among these floating tentacles, there were many dead small fish and shrimps, entangled together into a ball, just like the remains of insects on a spider web. After seeing this thing, Du Yuqi immediately knew that he must have found the real owner, so he took out a fishing net, scooped it up, and then put it into the bucket that had been prepared long ago.

However, such a good start does not mean a great harvest. After walking around the river beach, Du Yuqi was sad to find that he had only found this one blue complex algae. He shook his aching neck and found that almost three hours had passed. He was a little hungry. The kayak was wet and small, so he simply paddled ashore and found a large rock to sit on. Then he opened three bowls of instant rice in one go to prepare for lunch.

While waiting for the instant rice to heat up, Du Yuqi observed the surrounding environment and found that the scenery was really nice, very quiet and unique. Coupled with the faint mist, it felt like he had arrived in the misty Jiangnan on Earth. But who knew that there was a murderous intention lurking here?

He couldn't help but think of one more thing at this moment. It seemed easy to catch the blue algae at this moment, but the next goal was to get the chip. The difficulty of doing this could be said to be ten times greater than this. The key was that Duize's sister still needed the chip to save her life. It was really embarrassing. Fortunately, the Empire Test Field was in turmoil now. Although Du Yuqi didn't know why, the more muddy the water here was, the easier it would be for him and his gang to fish in troubled waters. He could only pray silently in his heart for more people to come.

Then Du Yuqi started to eat the rice, one box after another, and a bowl of seaweed egg drop soup, blowing on it while drinking. But at this moment, he suddenly felt something was wrong, as if the surroundings suddenly became quiet, the croaking of frogs, the chirping of birds, and the chirping of insects seemed to have disappeared! Only the sound of the river running gently could be heard!

"What's going on!" Du Yuqi stood up suddenly, the Soul Rift Blade was unsheathed, not only that, he also held the Bone of Hess in his left hand. This left sheath and right blade look may seem non-mainstream, but it is actually his strongest state.

Then, a quick shaking was seen in the bushes a few dozen meters away, and then a blood-red cat demon slowly emerged from it, with fierce eyes. After looking at Du Yuqi, it even raised its right paw and licked it, and then slowly approached. It was the ferocious and bloodthirsty cat demon! !

At this time, Du Yuqi could escape immediately by jumping into the river, but he was also worried because the water on the riverbed behind him was flowing slowly, almost as slow as a lotus pond. If he jumped in, the water would be at most up to his waist, and he would be stuck in the mud. What if Holmes' information was wrong, or if this bloodthirsty cat demon did not take the usual route and was not afraid of water and jumped down, then Du Yuqi would be extremely passive.

More importantly, Du Yuqi was also somewhat proud at this time. Even though others described this place as very dangerous, it would be too embarrassing for him to flee in panic just because of a bloodthirsty cat demon!

Suddenly, the bloodthirsty cat demon fell forward, then jumped up in an instant and pounced towards Du Yuqi. When it was halfway out, the pads on its claws suddenly retracted, revealing its terrifying claws.

After seeing this guy's claws, Du Yuqi had a new understanding of the wounds on those unlucky guys! Because the claws of this bloodthirsty cat demon are too abnormal, sharp as hooks, up to ten centimeters long, and there are a lot of jagged sharp spikes on the edges of the claws, shining with a sharp metallic luster.

Not only that, even when the claws scratched in the air, a faint blue-black mist would be left behind, as if the weapon was enchanted. The difference was that this should be the biological instinct of the bloodthirsty cat demon after it mutated, which can be called a natural enchantment!

At this time, the bloodthirsty cat demon pounced at an incredibly fast speed. Du Yuqi did not dare to use any skills. He could only dodge to the side as quickly as possible and swing his sword to slash back. The bloodthirsty cat demon twisted its body in the air, and its sharp claws collided head-on with Du Yuqi's Soul-Splitting Blade in the air. There was a clanging sound of metal colliding, and Du Yuqi's weapon that was slashing towards its waist was knocked away.

However, after the bloodthirsty cat demon landed on the ground, the long hair on its back suddenly stood up and made a stabbing motion. It was obviously enraged, and it let out an angry cry. Du Yuqi also noticed that the claw that collided head-on with the Rift Soul Blade had begun to bleed.

"Can you use my weapon just because you want to?" Du Yuqi sneered in his heart.
